According to the actual length of the pipeline, the winding mechanism 6 is adjusted to engage with the distance adjusting mechanism 10. Start the winding mechanism 6, and the winding mechanism 6 can drive the distance adjusting mechanism 10 to work. The distance adjusting mechanism 10 can drive the two steel wire ropes 7 to approach or move away from each other through the outward pushing mechanism 9 and the winding mechanism 6, so as to drive the two bearing mechanisms 8 to approach or move away from each other. After the adjustment is completed, the winding mechanism 6 is adjusted to the reset position. If it is convenient to move the device directly above the pipeline, then put the two bearing mechanisms 8 on the pipeline and rotate the control end of the bearing mechanism 8 to press the pipeline tightly. Start the winding mechanism 6, and the winding mechanism 6 can wind the steel wire rope 7, so as to drive the pipeline on the bearing mechanism 8 to move upward. If it is not convenient to move the device directly above the pipeline, then place the device near the pipeline, hoist the bearing mechanism 8 to above the platform 3 through the winding mechanism 6, turn on the outward pushing mechanism 9, and the outward pushing mechanism 9 can push the bearing mechanism 8 outward for a certain distance through the steel wire rope 7, and then lower the bearing mechanism 8 to fix the pipeline. After the bearing mechanism 8 fixes the pipeline, turn on the winding mechanism 6 to wind the steel wire rope 7. After raising the pipeline on the bearing mechanism 8 to an appropriate height, move the device through the moving wheels 2.

[0036] As Figure 3 As shown, as a preferred embodiment of the present invention, the driving assembly 62 includes: a first power member 621 fixedly installed on one of the support plates 4, a connecting plate 622 fixedly connected to the output shaft of the first power member 621, a threaded rod 623 rotatably arranged on the connecting plate 622, and a guide rod 624 fixed to the connecting plate 622 on one side of the threaded rod 623; a rotating block 625 rotatably installed on the protective cover 61, the end of the threaded rod 623 away from the connecting plate 622 is rotatably connected to the rotating block 625, the end of the guide rod 624 away from the connecting plate 622 is fixedly connected to the rotating block 625, and a turning handle 626 for controlling its rotation is fixed on the threaded rod 623; a sleeve 627 sleeved on the guide rod 624 and threadedly connected to the threaded rod 623, and a first gear 628 that can be meshed with the second gear 63 is fixed on the sleeve 627.

[0037] When hoisting a pipeline, after the pipeline is fixed to the carrying mechanism 8, the first power member 621 is turned on. The output shaft of the first power member 621 drives the connecting plate 622 to rotate, thereby driving the first gear 628 to rotate through the threaded rod 623 and the guide rod 624. The rotation of the first gear 628 drives the second gear 63 to rotate, the second gear 63 drives the hexagonal rod 64 to rotate, and thus drives the winding drum 65 to rotate.

[0039] When fixing the pipeline, place the pipeline on the lower arc plate 83, rotate the handle 84, the handle 84 drives the driving bevel gear 85 to rotate, the driving bevel gear 85 drives the driven bevel gear 87 and the threaded cylinder 86 to rotate. When the threaded cylinder 86 rotates, the threaded column 88 can push the upper arc plate 89 and the stabilizing sleeve 811 to move downward along the stabilizing column 810. When the upper arc plate 89 moves downward, the pipeline on the lower arc plate 83 can be pressed and fixed.

[0041] As Figure 5As shown, as a preferred embodiment of the present invention, the power assembly 92 includes: a dust cover 921 fixedly installed on the support cover 91. A second power member 922 installed on the support cover 91 is provided inside the dust cover 921. The output shaft of the second power member 922 is fixedly connected to a driving gear 923. The driving gear 923 meshes with a driven gear 924 rotatably installed on the support cover 91.

A guiding rod 927 is fixedly connected to the inner wall of the support cover 91 at both ends. A guiding sleeve 928 fixedly connected to the rack 926 is sleeved on the guiding rod 927. An output gear 929 is rotatably installed inside the support cover 91 and meshes with the rack 926. The rotating shaft of the output gear 929 is fixedly connected to the shaft rod 93.

[0042] If the device is not convenient to move directly above the pipeline, then turn on the second power member 922. The second power member 922 is specifically a motor. The output shaft of the second power member 922 drives the driving gear 923 to rotate. The driving gear 923 drives the driven gear 924 and the lead screw 925 to rotate. When the lead screw 925 rotates, the rack 926 and the guiding sleeve 928 can slide along the guiding rod 927. The movement of the rack 926 drives the rotation of the output gear 929. When the output gear 929 rotates, it can drive the shaft rod 93 to rotate, thereby driving the pulley 96 on the extension plate 94 to turn outwards. Thus, the load-bearing mechanism 8 can be driven to move outwards through the steel wire rope 7, and then it is convenient to fix the pipeline.

[0043] As Figure 1 、 Figure 2 and Figure 6 As shown, as a preferred embodiment of the present invention, the distance adjustment mechanism 10 includes: a lead screw 101 rotatably connected to the two support plates 4 at both ends.

The thread directions of the lead screw 101 on both sides of the partition 103 are opposite. A threaded block 104 is threadedly sleeved on the lead screw 101 and distributed on both sides of the partition 103. A first collar 105 is fixedly arranged on the threaded block 104. The winding drum 65 is rotatably arranged inside the first collar 105. A sleeve 106 has one end hinged to the first collar 105. A sleeve rod 107 is slidably arranged on the sleeve 106. A second collar 108 is hinged on the sleeve rod 107. The pulley 96 is rotatably arranged inside the second collar 108.

[0044] Embodiment 2 A shock-absorbing pipeline hoisting method for a thermal power plant provided by an embodiment of the present invention includes: When adjusting the distance between the two bearing mechanisms 8, first drive the extrapolation mechanism 9 through the drive assembly 62. The extrapolation mechanism 9 drives the two bearing mechanisms 8 to approach or move away from each other through the distance adjustment mechanism 10, so as to realize the adjustment of the distance between the two bearing mechanisms 8, and then make the device adapt to pipes of different lengths.

[0045] Specifically, when adjusting the distance between the two bearing mechanisms 8, first rotate the handle 626. The handle 626 drives the threaded rod 623 to rotate. When the threaded rod 623 rotates, the bushing 627 can drive the first gear 628 to slide along the guide rod 624 until the first gear 628 meshes with the third gear 102. Then turn on the first power member 621. The output shaft of the first power member 621 drives the first gear 628 to rotate, thereby driving the third gear 102 and the lead screw 101 to rotate. When the lead screw 101 rotates, the threaded block 104 can drive the two first collars 105 to approach or move away from each other. When the two first collars 105 approach or move away from each other, they can drive the two second collars 108 to approach or move away from each other through the sleeve 106 and the sleeve rod 107, thereby driving the two winding drums 65 and the pulleys 96 to approach or move away from each other. Thus, the two bearing mechanisms 8 can be driven to approach or move away from each other through the steel wire rope 7, so as to realize the adjustment of the distance between the two bearing mechanisms 8, and then the device can be made to adapt to pipes of different lengths.
