The clamping assembly 5 comprises a fixed shaft 51, clamping jaws 52 located on both sides of the fixed shaft 51 and a driving mechanism 53, the clamping jaws 52 are hingedly connected to the fixed shaft 51, the driving mechanism 53 can drive the clamping jaws 52 to rotate around the axis of the fixed shaft 51 to realize the opening and closing of the clamping jaws 52 and realize the clamping operation of the pipeline.

[0049] In an embodiment, first, the pipe laying device is moved to the position where the pipe is to be laid by the moving assembly 2, then the support legs 22 are activated to increase the grip of the support assembly 1 with the ground, and the stability of the pipe laying device when in contact with the ground is improved. Then, the counterweight is installed in the counterweight assembly 3, further increasing the stability of the pipe laying device relative to the ground, to prevent the support assembly 1 from tipping over when lifting the pipe. Then, the coarse adjustment telescopic rod 41 of the adjusting assembly 4 is extended to move the clamping assembly 5 to the position where the pipe is clamped, and the driving mechanism 53 of the clamping assembly 5 drives the clamping jaw 52 to open to clamp the pipe. After the clamping assembly 5 clamps the pipe, the coarse adjustment telescopic rod 41 is retracted to lift the pipe. The adjusting assembly 4 moves along the lifting beam 12 towards the trench to move the pipe above the trench. Finally, the coarse adjustment telescopic rod 41 is extended to move the pipe to the trench, and the fine adjustment assembly 42 is extended to increase the range of motion of the pipe, facilitating the butt joint installation between the pipe and the pipe.

[0050] It should be noted that when the fine adjustment assembly 42 adjusts the pipe, the adjusting block 421 releases the steel wire rope 425 to make the limiting block 422 disengage from the mounting seat 423, that is, the adjusting block 421 pulls the clamping assembly 5 fixed to the mounting seat 423 through the steel wire rope 425, that is, the clamping assembly 5 is lifted through the steel wire rope 425, and lifting the clamping assembly 5 through the steel wire rope 425 can maintain a larger range of motion of the clamping assembly 5, which is more conducive to the installation and butt joint of the pipe. Second, the adjusting block 421 releases the steel wire rope 425 to gradually disengage the circular table column 424 of the mounting seat 423 from the circular table groove 4221 of the limiting block 422, and when the circular table column 424 disengages from the circular table groove 4221, the range of motion of the circular table column 424 gradually increases, that is, the range of motion of the clamping assembly 5 in the state of being lifted through the steel wire rope 425 is adjusted by adjusting the release length of the steel wire rope 425, so that the clamping assembly 5 can maintain an appropriate range of motion, neither too small to make it difficult to adjust the position of the pipe, nor too large to make it difficult to realize the butt joint of the pipe. The relative position between the circular table groove 4221 and the circular table column 424 is adjusted through the steel wire rope 425, and then the clamping assembly 5 maintains an appropriate range of motion, which is helpful to realize the installation and butt joint of the pipe.

[0051] Preferably, the adjusting block 421 comprises a shell 4211, a collection roller 4212 located in the shell 4211, and an adjusting handle 4213 for driving the collection roller 4212 to rotate, and the shell 4211 is provided with a rope hole 4214 at the bottom, one end of the steel wire rope 425 is wound around the collection roller 4212, and the other end is fixed to the circular table column 424. The adjusting handle 4213 adjusts the contraction and release of the steel wire rope 425 by rotating the collection roller 4212.

[0052] In an embodiment, when the fine adjustment assembly 42 is adjusted, the worker rotates the adjustment handle 4213, and the corresponding collecting roller 4212 rotates to release or collect the steel wire rope 425, so as to adjust the vertical height of the mounting seat 423 and the clamping assembly 5 fixed to the mounting seat 423. One end of the steel wire rope 425 is wound to the collecting roller 4212, and the other end is fixedly connected to the circular column 424 through the rope hole 4214. The length of the steel wire rope 425 is adjusted, as shown in the figure, the circular column 424 moves downward in the vertical direction, the gap between the circular column 424 and the circular groove 4221 increases, the circular column 424 has a shaking space in the circular groove 4221, and therefore, the clamping assembly 5 can shake within the limitation of the circular groove 4221, so as to facilitate the laying and installation of the pipeline. Figure 11

[0053] Preferably, the bottom of the limiting block 422 and the bottom of the limiting groove 4231 are provided with the matching rounded corners 4222, so as to facilitate the matching butt joint between the limiting block 422 and the limiting groove 4231. The height of the limiting block 422 is H, and the depth of the limiting groove 4231 is h, and 10h<H. The depth of the limiting groove 4231 is limited, so as to reduce the hindering of the limiting groove 4231 to the free movement of the clamping assembly 5.

[0054] In an embodiment, the bottom of the limiting block 422 is provided with the rounded corner 4222, which is helpful for the downward insertion of the limiting block 422 into the limiting groove 4231. The limiting groove 4231 is provided with the rounded corner 4222 matched with the limiting block 422, so as to facilitate the accurate butt joint between the limiting groove 4231 and the limiting block 422. The depth of the limiting groove 4231 is not too deep. The depth of the limiting groove 4231 will hinder the shaking degree of the circular column 424 in the process of disengaging the limiting block 422 from the limiting groove 4231. That is, when the limiting block 422 is still located in the limiting groove 4231, the circular column 424 cannot shake in the horizontal direction relative to the circular groove 4221 when the steel wire rope 425 is elongated and the circular column 424 is disengaged from the circular groove 4221. Therefore, the height of the limiting groove 4231 is limited, so as to reduce the influence of the limiting groove 4231 on the movement range of the clamping assembly 5.

[0055] Preferably, the driving mechanism 53 comprises a positioning block 531 fixed between the two clamping jaws 52, an adjustment rotating shaft 532 penetrating through the positioning block 531 and being rotationally connected with the positioning block 531, and a rotating handle 533 mounted to the end of the adjustment rotating shaft 532.

The rotating handle 533 is twisted to realize the opening and closing operation of the two clamping jaws 52.​

[0056] In an embodiment, the handle 533 is screwed in a forward direction to drive the adjusting shaft 532 to rotate in a forward direction. Since the adjusting shaft 532 is screwed with the connecting block 522 and the center of the adjusting shaft 532 is rotationally limited with the positioning block 531, when the adjusting shaft 532 rotates, the two connecting blocks 522 will move away from the positioning block 531 relative to the adjusting shaft 532, thereby driving the clamping pieces 521 on both sides of the positioning block 531 to present an open state. Similarly, the handle 533 is screwed in a reverse direction to move the clamping jaw 52 to present a closed or clamping state.

[0057] Preferably, the clamping assembly 5 further comprises a safety rope 54 fixed to the side wall of the clamping jaw 52, and a safety sleeve 541 fixed to the clamping jaw 52 and matched with the safety rope 54.

[0058] In an embodiment, when the clamping assembly 5 clamps the pipeline, the coarse adjustment telescopic rod 41 is retracted to lift one end of the pipeline, and then the safety rope 54 is installed on the clamping jaw 52 by passing the bottom of the pipeline to prevent the pipeline from falling directly to the ground when it is separated from the clamping jaw 52, thereby playing a safety protection role.

[0060] In an embodiment, after the moving wheel 21 drives the pipeline laying device to move to the pipeline laying area, the hydraulic cylinder 222 drives the support disc 221 to move downward to support the pipeline laying device, and at this time, the pipeline laying device abuts against the ground through the support disc 221. The support leg 22 has the same principle as the existing support device around the crane and is used to support and stabilize the pipeline laying device.

[0061] Preferably, the counterweight assembly 3 is located on the side of the support frame 11 away from the clamping assembly 5 to prevent the support assembly 1 from tilting. The counterweight assembly 3 comprises a sliding seat 32 slidingly installed on the support frame 11, a counterweight box 33 fixed to the side of the sliding seat 32, and a bearing block 34 installed on the bottom of the sliding seat 32. The height of the bearing block 34 is greater than the length of the maximum compression amount of the elastic member 31, and the bearing block 34 is provided to prevent the elastic member 31 from being damaged when the counterweight assembly 3 is in action.

When the pipeline laying device needs hoisting operation, the counterweight is added to the counterweight assembly 3, and the counterweight assembly 3 extrudes the elastic member 31 under the action of the counterweight to abut the counterweight box 33 to the ground. In order to prevent the elastic member 31 before the sliding seat 32 and the moving plate 23 from being crushed, a bearing block 34 is arranged before the sliding seat 32 and the moving plate 23 to prevent the elastic member 31 from being crushed.

[0063] Preferably, a waterproof layer is attached to the inside of the counterweight box 33, and a valve 331 is arranged at the bottom of the counterweight box 33. The counterweight of the support assembly 1 can be realized by the way of water injection, which is convenient and fast.
