Description

The invention relates to a magazine for boring bars and / or Pipework on rock drilling machines, according to the preamble of Claim 1 and a corresponding rock drilling machine.

In known magazines, which are attached directly to the drill carriage are usually linear or revolver magazines. she require relatively little space and hardly disturb the overview. The the necessary changing device can be simple and therefore little be built prone to failure. In DE-PS 40 30 525 a Linear magazine suggested that the side of the drill carriage is attached, and the tools (boring bars or piping) are arranged in a row in the magazine. To be changed moved the tools in the magazine and then the whole thing Move magazine to work. However, this is relative to move large masses, and the changing process is time consuming.

DE-OS 37 38 116 shows a revolver magazine on one side the drill carriage, while on the other side the Exchange device with clamping device and transverse displacement is arranged. This means that no additional magazine can be attached there become. The number of on the scope of such a revolver magazine tools to be accommodated, as with the former Linear magazine, however limited.

Magazines for a larger number of boring bars on one or both sides of the drilling site are essentially only at installed drilling sites, e.g. B. derrick, known here Experience has shown that space requirements play a subordinate role.

In US 3,895,677 the extensive magazine is in front of the Drilling site, and the boring bars are using a crane system Gripping pliers brought from the magazine to the work site.

DE OS 3 614 199 shows magazines next to a drilling mast that can be rotated around a vertical axis, in a longitudinal axis is slidable and provided with an adjustable arm.

In addition to a large space requirement, however, the construction effort is considerably.

The invention is therefore based on the object, magazines for Inclusion of boring bars and / or piping and a associated changeover device to create, at a high Number of storage spaces and a simple changing facility takes up little space and directly on the drill carriage can be arranged.

This object of the invention is achieved with a magazine Features of claim 1 solved.

Appropriate configurations are the subject of the dependent Expectations. The magazine and the are preferred Exchange device placed next to the drill carriage, so that the Drilled directly to the drilling site using the shortest and straightest route can be.

Since one side of the drill carriage is usually free of attachments, while the other side with lines for the supply of the Drill head and the flushing device is partially installed on one side the magazine runs wide while it is on the other side is kept narrower for optimal use of space can be.

Since more boring bars are generally required than Piping, the narrower magazine can accommodate this are used, with the design of the storage spaces in Magazine and the changing device of the larger diameter of the Piping must be taken into account. For mounting the individual boring bars and piping in the magazine is on the ground fixed spigot and a movable one on the ceiling of the magazine Pin arranged as a latch. The movable pin is standing under spring load. The boring bar or the Piping through the changing device so far raised that the movable pin is held up in a rest. At the Inserting a tool is done by lifting it further Latch unlocked. When lowering the tool into the pin on the floor, the movable pin is relieved by the spring load pressed down and the tool held in the magazine. To one simple movement of the changing device with corresponding stops for the respective positioning received, the storage locations are preferably arranged in Longitudinal and transverse rows.

The changing device has a gripping device for receiving the boring bars or the piping. This must be followed by the tool recording, during transport and at the drilling site hold until it is on the rotary drive of the drill head and Coupling part is added. To bring in and out the Tools on fixed and movable spigot, balancing Height differences between the magazine and drill carriage and that To allow insertion into the coupling part is the Height of the gripping device on the changing device appropriate. This is preferably done by adjusting the height, which is operated by a hydraulic cylinder. For the respective limit of the stroke movement are limit switches as Pressure switch and provided as a touch switch.

For lateral movement of the gripping device and the These are height adjustments within the magazine area preferably arranged on a carriage, which in a over the Width of the magazine extending cross rail is movable and is driven by a rack and a gear motor. There are stops on the individual for positioning Rows provided in conjunction with a counter or Let the button control the relevant row. The cross rail in turn is attached to one of the carriages Guide rail laterally displaceable around the gripping device from the side of the magazine into the drilling points. The shift takes place between two end positions and can be carried out via a hydraulic cylinder.

The guide rail is preferably attached to a carriage, which runs lengthways along the magazine and the Gripping device in the individual transverse rows from which the Tool must be picked up or set. The longitudinal car runs in Rails, preferably on the long sides of the magazine are arranged to the largest possible distance from each other receive. For proper movement in the longitudinal direction preferably provided spindle drives on the rails preferably synchronous with one another via angular gears and shafts are connected to avoid jamming in the guides. Limit switches, Counters or one that starts at the stored tools Stop bar are provided.

Because the guide rail moves within the magazine and so that its length is fixed, it is sufficient for a wide one Magazine to get to the drilling site. With a narrow one Magazine it may be necessary to use it as a telescopic rail to train. The gripping device is advantageously by two in Distance from each other arranged jaw pairs, the synchronized by means of a common shaft and through one hydraulic cylinder each can be actuated. Because of the different dimensions, especially in diameter, from Boring bars and piping, it is therefore appropriate to have a magazine for the boring bars and a magazine for the piping to execute.

For quick mounting and dismounting or changing the magazine with the changing device are preferred between the Mounting frame on the drill carriage and, if necessary, with a Side support is attached to the frame of the chassis, and the Magazine frame detachable connections arranged. Likewise, for the simple attachment and removal or replacement of the bearing part detachable in the magazine between this and the magazine frame Connections may be provided. When training the detachable Connections and connections as quick connectors are reduced also the effort involved in mounting and dismounting.

To improve the introduction of the coupling points on the magazine or the bearing parts in the pockets of the quick couplings these are preferably with laterally widening upwards Provide guide surfaces. A particularly secure attachment of the Magazine, especially when there are high boring bars were spatially distributed with the arrangement of at least three Quick couplings.

For the rapid mounting and dismounting of magazines on the Construction site mostly used cranes on the drill carriage. For safe attachment of the load lifting devices are therefore at the Top of the magazines are preferably attached with eyelets. A Reduction of effort can also be achieved by arranging a Coupling point can be reached in the pivot point of a side support. This is easily accessible and therefore useful with the Equip locking device.

The boring bars or piping are preferably in one closely arranged, ordered bundles arranged in the magazine, whereby for Recording for removal and insertion into the magazine Hub traverse can be provided. It can when changing the same dimension the bundle alone or when changing the Dimension the bundle together with the top retainer can be replaced quickly in one operation. The Bundle with the individual boring bars or piping formed by a lower locking pin plate at one end and an upper perforated plate, the hole diameter of which is somewhat larger than the tool diameter and the one closure of the holes the upper side for holding. After that The closure is simply pulled back in and the Perforated plate lifted by a lifting device in order to upper holding device until the next replacement there to be held.

In such a change process with the upper one Retaining device in the lifting traverse is this before Removed from the lifting beam and then unlocked with the frame locked the changing device. The lower locking pin plate is preferred here after changing from the lifting beam unlocked and locked to the frame of the changing device.

The bundle provided with boring bars or piping will thus by a lower locking pin plate and an upper one Perforated plate with inserted lock and by several Drawbars held together in a compact form as a unit. For horizontal transport and storage are appropriate, if necessary, removable towing eyes are attached. The Locking pin plate and possibly also the bearing plate for the Holding bolts of the holding device are preferred with interchangeable locking and retaining pins if necessary holes, their hole patterns for different Tool diameters are suitable. The locking pins of the lower one Locking pin plate and the lower ends of the retaining bolts Holding devices are to adapt to the respective Tool diameter and the shape of the tool ends adapted. The Locking on the upper perforated plate can preferably be done by Slidable locking bars for two rows of tools be formed.

The frame of the changing device is on the outside Introduction of the bundle of tools in the lifting crossbeam necessary area preferably designed open. The lifting traverse is for installing, removing and changing the bundle alone, possibly also the upper holding device on one side also openly trained. With the appropriate design of the Hubtraverse can the frame of the changing device in its the upper part on its outside, however, also remain closed. For reasons of standardization and simple construction of Exchange device as well as size and arrangement of the bundles of Boring bars or tubing should change the fixtures on both sides of the drill carriage have the same dimensions, or be formed in mirror image.

To ensure that the boring bars and / or are in perfect order Ensuring piping (tools) in the magazine is one Control designed so that when occupying the exchange place Tool closest to the magazine and when clearing the the most distant storage location is approached. In the Delivery and return of tools is for the Operator safety and collision prevention Check the free space between the changing device and the Place of use through light barrier or a closed grille expedient, as well as monitoring the distance between the drill head and coupling part by checking the lifting height of the drill head Position transmitter.

After a tool has been delivered to the place of use the drill head is moved onto the tool, and a Position detector indicates the opening and retrieval of the Gripping device free. The gripping device then returns to the Exchange position back. Will another tool on the The next tool is needed command from the magazine. For feasibility a return is in addition to checking the free space an occupancy detector is arranged there at the change position. Is the place is occupied and the withdrawal of a tool prepared, the one in the change position is prepared Tool stored in the magazine and the gripping device brought back.

Before the delivery of a tool to the The drilling or operating point is the change position through a Tool. This ensures that the delivery can be done quickly, the tool does not have to come out of the Magazine can be fetched, so it is ready to go in the Exchange position. The exchange position can also be the Be the parking position of the gripping device. It stands outside the actual storage space of the magazine and does not prevent the Change the bearing part or the bundle of tools.

The preferably provided lifting movement of the gripping device serves once snapping the tools into and out of the Holding device of the magazine. In addition to the Zero position further height positions can be approached. The one and Exit from the magazine is only in the Zero position. When storing a tool takes place at Reaching the storage position, lifting to the highest position, to unlock the locking pin. After that is lowered to the entry into the retaining bolt on the Retaining bolt plate. After loosening the gripping device and The gripping device then moves back to the zero position in the change position.

When picking up a tool, the gripping device moves in the Zero position in the magazine, grips in this position Tool, lift it up until the retaining pin clicks into place returns to the zero position and returns with the tool the exchange place back.

When delivering a tool from the exchange place to the After reaching the drilling point, the gripping device moves Working position down until the tool is in the Coupling point located tool is inserted. Now he can Drill head lowered to the top of the tool and and in whose sleeve is screwed in. Now the command to Opening and return of the gripping device are given. she drives back to zero height before going to the exchange place returns. The control of the transverse and longitudinal movement of the Gripping device is preferably carried out by an electronic Coordinate control via stepper motors with counter and Route change.

The above described in connection with the magazines, particularly advantageous method has the advantage that the Drill mount with a double drill head only when delivering one Double shot is needed and therefore little time when changing for the actual drilling is neglected because the assembly the shots by means of the changing devices of the magazines during the actual drilling time in a standby position outside of the drilling area.

Even when dismantling, a double shot from the carriage in the Ready position and the double drilling head immediately used again to get the next double shot, while the exchange devices the individual shots in the Bring back magazines. Only individual returns Linkage shots by means of the changing device in the above described magazine is also possible. To carry out the The procedure is expedient, both magazines approximately the same height next to the drill carriage and the Height movement of the change device for the pipe shot down and that for the boom shot upwards by more than to train half the length of the boom.

Because of the generally smaller dimension narrower version of the magazine for the boom sections can the standby position between this and the Drill mount can be arranged. The location of the standby position in the longitudinal direction should preferably be in front of the area of Free space of the double drilling head and at the height of the Change position can be arranged in the magazines.

The appropriate horizontal arrangement of the magazines and one swiveling changing device on the frame of the Rock drill on both sides of the free space Transport position of the drill carriage relieved in an advantageous In addition, the mast, its storage and the lifting cylinders. Of the The mast and its storage therefore do not need to be reinforced or stronger be interpreted. Likewise, the lifting cylinders are not additional claimed.

The changing device removes the horizontal in the magazine stored tools, grips them and then swivels around one horizontal axis in the inclined position or in the vertical of the Drill carriage. After a lateral movement to the location of the The drilling site passes the tool to the drilling device. The Storage from the drilling site in the magazine takes place in reverse order. This can be done by a corresponding Arrangement of magazine, changing device and swivel axis be achieved in the extension of the Swivel axis of the drill carriage is located. This simplifies the Synchronization of the changing device with the drill carriage.

The changing device is preferably on a swivel arm arranged, which is moved by its own lifting cylinder. At the horizontal part of the swivel arm is an adjustable on it Longitudinal carriage arranged in which the transverse guide can be moved is stored in which the cross carriage for a gripping or Pliers telescope is arranged transversely. At the end of The gripping pliers, which hold the tools, are arranged in the pliers removed from the magazine. To move in side by side The pliers telescope on the lateral guide is the storage location laterally adjustable. Acting among themselves lying bins is done by moving the Gripping pliers in the pliers telescope.

Another can be used to swing out to the side to the drilling point Leadership on the transverse guide may be provided on the carriage on the Swivel arm is arranged. After gripping a tool, This is done by lifting and cross-conveying to a standby position Swing the swivel arm up until the tool is parallel to the Mast of the drill carriage lies. There the swivel arm with the Mast, if necessary, be locked. By extending the The tool on the gripping pliers and the Plier telescope moves to the drilling site, where the drilling head Tool takes over.

The exchange device either moves into one Ready position for removing a tool to the side or returns to the magazine by lowering the swivel arm Ready position for delivery of a tool. The magazines are thus stored in a stable manner on the frame of the Rock drilling machine and can be removed from lifting eyes become. Since the exchange device after swiveling the Drill mount in the horizontal transport position over the height of the Rock drilling machine and the magazine protrudes through it Another rotation from the transfer position is preferred after be brought into the transport space below.

A convenient solution for the arrangement of the movement paths Changing device results in a version with Guide rods and roles by summarizing each two axes of motion on two double carriages. The longitudinal carriage on the horizontal part of the lifting arm has another Roller arrangement for the cross adjustment, the cross carriage for the Transverse movement of the gripping tongs another roller arrangement for the vertical movement of the pliers guide.
