Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
Fig. 2 shows the structure chart of the control appliance for pile tube pumping cloth system according to the embodiment of the present invention, and wherein said pile tube pumping cloth system can comprise the concrete pump set, pipe pile mould and pipe pile mould conveying arrangement as shown in Figure 1.As shown in Figure 2, this control appliance 500 can comprise: receiver 501, for receiving concrete actual weight signal when described the concrete pump set one-stroke terminates in described pipe pile mould and the actual travel distance signal of described pipe pile mould conveying arrangement during this stroke; And controller 502, the actual weight that during calculating described one-stroke for the concrete actual weight in described pipe pile mould when terminating according to received concrete actual weight and front one-stroke, described pipe pile mould inner concrete increases; The actual weight increased according to described concrete and described actual travel distance calculate the concrete actual weight of unit length in described pipe pile mould; The travel speed of described pipe pile mould conveying arrangement during the lower one-stroke of described the concrete pump set is adjusted according to the actual weight of the concrete actual weight of described unit length, the concrete theoretical weight of unit length and described concrete increase.
Term described above " stroke " refers to oil cylinder piston in the concrete pump set and/or the process of concrete cylinder piston from original position to final position, and after completing one-stroke, oil cylinder piston and/or concrete cylinder piston commutate, and then carry out lower one-stroke.
The concrete theoretical weight of unit length recited above can be default, also can be to determine based on the predetermined travel speed of oil cylinder piston stroke in described the concrete pump set and described pipe pile mould conveying arrangement.In this case, described receiver 501 is also for receiving oil cylinder piston stroke signal in described the concrete pump set; And the concrete theoretical weight of described unit length also determined by described controller 502 for the time needed for the predetermined travel speed of described oil cylinder piston stroke, described pipe pile mould conveying arrangement and described one-stroke.The concrete theoretical weight of the unit length determined in this way is more accurate, goes for different the concrete pump sets.
Particularly, controller 502 is after receiving oil cylinder piston stroke signal, it can calculate the volume of concrete V of the concrete pump set output according to piston stroke, then according to this volume V, pump volumetric efficiency K and concrete density ρ, the weight concrete G of the concrete pump set output is calculated by following equation:
G=V × K × ρ equation (1)
Time t needed for the concrete pump set one-stroke is certain, and pipe pile mould conveying arrangement has a predetermined traveling speed v
0(desired ride speed), according to this predetermined traveling speed v
0the operating range S of pipe pile mould conveying arrangement during can drawing one-stroke with the time t needed for one-stroke.That is, during one-stroke, pipe pile mould conveying arrangement travels S rice, and pipe pile mould pumping installations carries the concrete (weight is G) of coming all to be distributed in the scope of S rice in pipe pile mould.Controller 502 can obtain the concrete theoretical weight of unit length according to the weight concrete G as above calculated and described operating range S.
Once determine the concrete theoretical weight of unit length, during whole cloth, the concrete theoretical weight of this unit length is constant.
The actual weight specifically describing controller 502 and how increase according to the concrete actual weight of described unit length, the concrete theoretical weight of unit length and described concrete is adjusted the method for the travel speed of described pipe pile mould conveying arrangement below.
First, controller 502 after the concrete actual weight calculating unit length in pipe pile mould, its weight concrete difference Δ g that can draw under described unit length according to the concrete theoretical weight of unit length.Such as, suppose that the concrete theoretical weight G1 of unit length is 1kg/m.After one-stroke terminates, controller 502 determines that the actual weight g that pipe pile mould inner concrete increases is 0.9kg, and the actual travel distance of pipe pile mould conveying arrangement is 1m, and therefore, it can determine that the concrete actual weight G2 of unit length is 0.9kg/m.Thus, controller 502 can according to the concrete actual weight G2 of the concrete theoretical weight G1 of described unit length and described unit length, and the weight concrete difference Δ g calculating under described unit length (1m) is 0.1kg.
After drawing weight difference Δ g, controller 502 according to the concrete theoretical weight G1 of this weight difference Δ g and described unit length, can calculate the range difference Δ L between the theoretical operating range of described pipe pile mould conveying arrangement during described one-stroke and actual travel distance.Still for above-mentioned example, controller 502 can draw range difference Δ L=Δ g/G1=0.1kg/1kg/m=0.1m.
The weight concrete that the actual weight g that described concrete increases by described controller 502 ought to export as one-stroke under the concrete pump set.Such as, in the examples described above, g=0.9kg, therefore, the concrete pump set during lower one-stroke given tacit consent to by controller 502 only can carry the concrete of 0.9kg.Thus, controller 502 can further based on the theoretical operating range L1 of concrete theoretical weight G1 calculating described pipe pile mould conveying arrangement during lower one-stroke of described unit length.Still for above-mentioned example, controller 502 can draw L1=g/G1=0.9kg/1kg/m=0.9m.
During obtaining range difference Δ L and described lower one-stroke described pipe pile mould conveying arrangement theoretical operating range L1 after, controller 502 can calculate the actual travel distance L2 of described pipe pile mould conveying arrangement during lower one-stroke, wherein Δ L=L1-L2.Still for above-mentioned example, controller 502 can draw L2=L1-Δ L=0.9m-0.1m=0.8m.
Afterwards, controller 502 just time t needed for the actual travel distance L2 of pipe pile mould conveying arrangement described during described lower one-stroke and described one-stroke can calculate the travel speed v of described pipe pile mould conveying arrangement during lower one-stroke, i.e. v=L2/t.Still for above-mentioned example, suppose the time t=1s needed for one-stroke, controller 502 can draw v=L2/t=0.8m/1s=0.8m/s.
The speed of the pipe pile mould conveying device during the lower one-stroke of the concrete pump set is adjusted to calculated travel speed by controller 502, such as 0.8m/s.
Thus, the travel speed of pipe pile mould conveying arrangement during the actual weight that can increase according to pipe pile mould inner concrete during this stroke and the actual travel distance of pipe pile mould conveying arrangement revise stroke next time, reduce the difference between concrete actual weight and theoretical weight, thus ensure that cloth is even.In addition, the concrete actual weight in pipe pile mould records after one-stroke terminates, and therefore, avoids because in concrete delivery service, conveyance conduit vibration, on the impact of measuring, makes metering more accurate.

Because the concrete pump set is after completing one-stroke, oil cylinder piston wherein and/or concrete cylinder piston commutate, and after completing commutation, continue pumping (namely starting lower one-stroke).When commutating, the concrete pump set is instantaneous to be exported without concrete.Weight sensor 700 detects just in the meantime, instead of detects in real time, therefore prevents the conveyance conduit vibration caused because of concrete conveyance on the impact of metering, makes measurement result more accurate.
As mentioned above, the concrete theoretical weight of unit length can be default, also can be to determine based on the predetermined travel speed of oil cylinder piston stroke in described the concrete pump set and described pipe pile mould conveying arrangement.In this case, described control system can also comprise: device for detecting distance of travel 800, for detecting the stroke of oil cylinder piston in the concrete pump set, for the concrete theoretical weight under control appliance determination unit length.
