[0037] Furthermore, the side wall of the fixed ring 314 is hinged to one end of the movable rod 315, and the other end of the movable rod 315 is hinged to the top of the clamp arm 319.

[0038] When the device is working (or in use), the hydraulic telescopic arm 4 is driven by the hydraulic telescopic rod 2 to move up and down. When hoisting is required, the electromagnet 312 is energized so that the electromagnet 312 generates magnetic force to adsorb the metal block 311, so that the metal block 311 drives the slider 39 to descend, so that the slider 39 drives the pawl 38 to release the meshing with the ratchet 36, so that the ratchet 36 releases the one-way limit, and the worm 32 is driven to rotate by the starting motor 34, so that the worm 32 drives the worm wheel 33 to rotate, and the rotation of the worm wheel 33 drives the main cable 35 to release the line. , so that the end of the main cable 35 drops due to gravity and is fixed by a lifting ring.

When moving, the top of the arm 319 will squeeze the top of the retaining tube 317, so that the retaining tube 317 is squeezed and descends, and the retaining tube 317 drives the sealing plate 322 to descend, so that the bottom gap of the through tube 321 leaks out, and the curing liquid inside the through tube 321 flows out and flows to the rubber clamp 323 and the main cable 35 to be coated through the rubber clamp 323, so that the main cable 35 can be cured during the ascent to prevent it from oxidation, and the curing liquid can be transported to the through tube 321 through the delivery pipe 320, so as to ensure the liquid level of the curing liquid in the through tube 321.
