Further, as shown in Figure 1, described pedestal 1 comprises: parallel leading flank 10 and trailing flank 16, and left surface 12 and the right flank 14 of the vertical described leading flank of difference and trailing flank, the number of described the first hydraulic actuating cylinder 31 is two, be symmetricly set on the right side of described left surface 12 left sides and described right flank 14, described the first hydraulic actuating cylinder 31 is hinged on the described pedestal 1, and each described first hydraulic actuating cylinder connects a described holding part.Left surface 12 and right flank 14 tilt to intersect with end face 18 respectively, in order to be that the first hydraulic actuating cylinder 31 is connected slot milling by adapter shaft 39 with holding part 3, left surface 12 and right flank 14 intersect vertically with end face 18 respectively else if, then can make whole pipeline clamping body of tool long-pending huge, and be unfavorable for promoting holding part 3.
Further, described pipeline clamping device also comprises the second hydraulic actuating cylinder 51 that drives described tight lock part, described the second hydraulic actuating cylinder 51 is arranged on the described pedestal 1 and with described slide block 5 and is connected, can smooth drive by the second hydraulic actuating cylinder 51, can apply the required thrust of locking.
Further, as shown in Figure 1 to Figure 3, holding part 3 can own clamping pipeline, also can cooperate common clamping pipeline with pedestal 1.Described clamp has circular arc gripper jaw 35, the leading flank of described pedestal and trailing flank all have arc gripper edge 15, better, the utility model adopts described grasping part to be formed by described circular arc gripper jaw 35 and described arc gripper edge 15, like this, can take full advantage of the mechanism of pedestal, can make pedestal bear more Clamping force.Wherein, described arc gripper edge 15 is positioned at the top of described grasping part, so that pipeline is come in and gone out from the bottom.Described holding part is a pair of clamp, and described pedestal 1 and described clamp form the grasping part in grip tube road.
Described clamp is provided with the screens section 37 that locks with described slide block, as shown in Figure 5, described screens section 37 has the stressed place 371 of vertical described chute 5 length directions, be positioned at locked position at described slide block 5, the described screens of 5 pairs of described slide blocks section 37 is spacing, 5 pairs of described stressed places 471 of described slide block apply the clamping force that stops described clamp to rotate, vertical described chute 5 length directions of described clamping force.
As shown in Figure 6, stressed place 371 can be for bearing surface or stressed stupefied or stress point, and better, the utility model adopts stressed place 371 to be bearing surface, like this stability under loading, and force dispersion.Be positioned at locked position at described slide block 5, main stressed of clamp is the bearing force F2 at pipeline 7 applied pressure F1,5 pairs of stressed places 371 of slide block and the bearing force N of 33 pairs of clamps of hinge, in addition, relatively above-mentioned each power of the gravity of clamp itself can be ignored, therefore, for the ease of analyzing, the gravity of clamp itself no longer counts consideration.In pressure F1, bearing force F2 and bearing force N, bearing force N is directed to pedestal and provides, the pressure F1 of pipeline passes on the pedestal, provide by pedestal, bearing force F2 derives from the dragging track face along its length of chute 50, the length direction of the perpendicular direction chute 50 of bearing force F2 that is to say that bearing force F2 also provides by pedestal.After locking, pressure F1, bearing force (coupling mechanism force) F2 that clamp is suffered and bearing force N are directly or indirectly from pedestal, with the first hydraulic actuating cylinder 31 and the second hydraulic actuating cylinder 51, no longer include relation.With the first hydraulic actuating cylinder 31 and the second hydraulic actuating cylinder 51 just in driving the process clamp clamping pipe and that promote slider locking, applied thrust, Deng locking finish after, just no longer need to be from the thrust of the first hydraulic actuating cylinder 31 and the second hydraulic actuating cylinder 51, so, after the locking, stop can not affecting locking to the second hydraulic actuating cylinder 51 fuel feeding, the problem that clamp is decontroled can not occur, because, the power F2 of locking is from chute 50 dragging track faces, but not from the second hydraulic actuating cylinder 51, after the locking, stop the first hydraulic actuating cylinder 31 fuel feeding, the problem that clamp is decontroled can not occur.
As shown in Figure 3, further, described hinge 33 is positioned on the extended line of described chute 50, like this, can guarantee when the second hydraulic actuating cylinder 51 promotes slide blocks 5 and is pushed against on the clamp, and the moment of torsion of the second hydraulic actuating cylinder 51 that clamp is suffered is less or be zero, keeps stable.Described screens section 37 is block or draw-in groove, and block or draw-in groove can both have the bearing surface that cooperates screens with slide block 5.What the utility model adopted in an embodiment is block.
Further, the number of described chute 50 is four, and described the first hydraulic actuating cylinder 31 also is four, and described chute is separately positioned on described leading flank and the trailing flank, and each side is provided with two symmetrical chutes.Like this, can disperse bearing force (coupling mechanism force) F2, alleviate the stressed of single chute.
Further, the thrust of described the first hydraulic actuating cylinder 31 and stroke are greater than thrust output and the stroke of described the second hydraulic actuating cylinder 51.That is to say that the first hydraulic actuating cylinder 31 is large hydraulic actuating cylinder, the second hydraulic actuating cylinder 51 is small cylinder, like this, and can reasonable coordination clamping and locking.
Further, as shown in Figure 4, the utility model provides another kind of locking effect better locking mechanism.This structure is with structure main difference among Fig. 3: be provided with the spring 6 that is connected with described slide block 5 in the described chute 50, described spring 6 is positioned at the described hinge of described chute 50 middle distances 33 end far away.For example, among Fig. 4, spring 6 is between the top and slide block 5 of chute, and spring 6 is generally pressure spring, also can be tension spring in some situation.Spring 6 one ends are fixed on the top of chute, spring 6 other ends are fixed on the slide block 5, other places, identical with the example structure of Fig. 3, for example, slide block 5 still is connected with the second hydraulic actuating cylinder 51, and the second hydraulic actuating cylinder 51 still can drive slide block 5 and slide, just for the convenience of view, the second hydraulic actuating cylinder 51 is not shown.
This locking mechanism with spring can store the part thrust of the second hydraulic actuating cylinder 51 and have the function that buffering is replied, and can regulate coupling mechanism force F2.The more important thing is, when required F2 is larger, chute 50 or slide block 5 might produce distortion, at this moment, the original coupling mechanism force F2 that is provided by chute is provided alone to be difficult to provide all coupling mechanism forces in the situation of chute distortion, the appearance of spring 6 then provides the scheme that overcomes this problem, and spring 6 can also provide along the pressure of the length direction of chute 50 or pulling force, more is conducive to locking.Also have; slide block 5 is owing to are connected connection with spring; even the second hydraulic actuating cylinder 51 breaks down or ruptures, need not the second hydraulic actuating cylinder 51 applied thrusts, slide block 5 can be subject to pulling force or the pressure of spring 6; thereby can normally slide into locked position; block screens section 37, realize locking, thereby; spring 6 can also in some cases, realize separately driving the function that slip reaches locked position.
Further, the utility model also provides a kind of Pipeline lift method, described Pipeline lift method comprises: drive holding part 3 with the first hydraulic actuating cylinder 31 and rotate and clamping pipe 7, then drive tight lock part, stop described holding part 3 to rotate, then promote described pipeline and in lifting, stop described the first hydraulic actuating cylinder fuel feeding, like this, the first hydraulic actuating cylinder stressed burden that alleviates hydraulic efficiency pressure system hardly in lifting.
As shown in Figure 7, working process of the present utility model is as follows: at first (with large hydraulic actuating cylinder (the first hydraulic actuating cylinder 31) retraction) guarantees that clamp is in open mode → close up clamp (claw) clamping pipe 7 → usefulness small cylinder (the second hydraulic actuating cylinder 51) promotion slide block 5 with large hydraulic actuating cylinder (the first hydraulic actuating cylinder 31) to tighten screens sections 37.When pipeline being promoted behind the chucking, institute is stressed passes to slide block 5 by clamp (claw) and pass to pedestal 1 again for it, so each hydraulic actuating cylinder is not subjected to the impact of thrust or pulling force again.
The scope in holder's prodigiosin grip tube of the present utility model road is 200mm-305mm (8 inches-12 inches).If adapt to the pipeline clamping of more size, only need pedestal and clamp are slightly changed.
The utlity model has following advantage: 1, this clamping device symmetrical configuration is stressed even.2, this clamping device is when clamping pipe, and clamped condition is pinned in the gripping mechanism action; In the Pipeline lift process, hoisting force is delivered on the pedestal, and hydraulic actuating cylinder is stressed hardly.Namely realize the function of clamping device, alleviated again the burden of hydraulic efficiency pressure system.
The above only is the schematic specific embodiment of the utility model, is not to limit scope of the present utility model.For each component part of the present utility model can make up under the condition of not conflicting mutually; any those skilled in the art; the equivalent variations of having done under the prerequisite that does not break away from design of the present utility model and principle and modification all should belong to the scope that the utility model is protected.
