Description
Technical field
The present invention is the floating ring of imbedded steel pipe corrosion detector probe that imbedded steel pipe corrosion detects, and relates to measurement and the piping system technical field of measuring magnetic variable, thickness linear dimension.
Background technology
For guaranteeing steel buried pipeline security of operation, generally all to regularly do online corrosion and detect with the tube inner corrosion detecting device to pipeline.But because long distance pipeline has pipe fittings such as a lot of elbows, threeway, circuit block valve at a station spacing interior conduit, detecting device is not moving linearly in pipeline, the distance of the relative detecting device axle of the probe on the ring is not to immobilize, by these positions the time, detector probe just has bigger skew radially.Present detecting device such as circuitously only depend on probe spring to regulate to this situation, in fact the radiai adjustment of probe spring is very limited, the adjusting when it can only satisfy welding bead tends to damage probe like this.
Summary of the invention
The objective of the invention is to invent a kind of energy carries out the steel pipe corrosion detection smoothly, safely by pipeline floating ring of imbedded steel pipe corrosion detector probe.
The present invention realizes that the technology path of above-mentioned purpose is that the ring that will probe be installed floats.As shown in Figure 1 and Figure 2, will be placed in exactly between the outer floating ring 2 of axis body 4 and the axis body 4 and be connected by a plurality of linkworks 3.Specifically be floating ring 2 with axis body 4 between be connected by 3～6 linkworks 3, linkwork 3 is made up of connecting rod 7, bracket I 5, bracket I I13, sleeve pipe I11, sleeve pipe II12, spherical plain bearing rod end 6, screw 9 and nut 8, connecting rod 7 two ends respectively connect a spherical plain bearing rod end 6 by nut 8, the spherical plain bearing rod end 6 of connecting rod 7 one ends is positioned on the bracket I 5 by screw 9, and the spherical plain bearing rod end 6 of connecting rod 7 other ends is positioned on the bracket I I13 by screw 9.
Bracket I 5 (see figure 3)s of linkwork 3 wherein are " E " shape structure, at its bottom fixed orifice are arranged, and the top occupies the hole of passing behind the screw 9 covers one sleeve pipe I11, and there is the screw that cooperates with screw 9 in the middle layer.
The bracket I I13 of linkwork 3 is a bathtub construction, at last ledge the hole of wearing screw 9 is arranged, and following ledge and top margin hole opposite position have screw, and bottom land has the hole that is connected with floating ring.
The connecting rod 7 of linkwork 3 has the pipeline section of the right side, levogyrate inner thread for two ends.
The screw 9 of linkwork 3 is a socket head cap screw.
The screw rod of the spherical plain bearing rod end 6 of linkwork 3 is worn screw 9 holes for the center has ball is contained in the bowl and bowl is connected the again right side, sinistral external thread.
The connected mode of connecting rod 7 and spherical plain bearing rod end 6 is that the spiro rod section of two right sides, left-handed spherical plain bearing rod end 6 screws on respectively behind the nut that matches 8 again that the two ends from connecting rod 7 are screwed into.
Spherical plain bearing rod end 6 inserts from the hole that occupies of bracket I 5, bracket I I13 respectively for overlapped packing rings 10 and sleeve pipe I11 by screw 9 after with the connected mode of bracket I 5, bracket I I13, after respectively filling up a sleeve pipe II12, the both sides of spherical plain bearing rod end 6 pass in the lump by screw 9, the screw thread of last screw 9 terminations is screwed into following screw, with spherical plain bearing rod end 6 location.
Sleeve pipe II12 is thick tube wall and with spherical plain bearing rod end 6 contact jaws edging is being arranged.
In a single day the linkwork 3 of this kind structure can be regulated the front and back position of probe by connecting rod 7, and can be by nut 8 location after regulating; Spherical plain bearing rod end 6 then not only has around the rotation of screw 9 with bracket I 5 bracket I I13, also because of the edging of spherical plain bearing rod end 6 and sleeve pipe II12, can make connecting rod 7 do low-angle rotation in the vertical direction of above-mentioned rotation.This just can satisfy the actual needs of pipe internal detector.
As seen, the present invention can pass through to press various pipe fittings, the pipeline section on the standard design pipeline smoothly, safely, and can guarantee to detect integrality, the accuracy of data.
