[0042] The connecting rope 7 is but not limited to a steel wire rope.

[0043] In some embodiments, the crossbar 3 is movably connected to the frame 1 via a plug-in rod 301. A plurality of plug-in rods 301 are fixed to the crossbar 3, and the plug-in rods 301 are arranged perpendicular to the crossbar 3. A receiving tube 2 corresponding to the plug-in rod 301 is fixed to the frame 1, and the plug-in rod 301 is movably connected to the inner side of the receiving tube 2. One of the plug-in rods 301 has a plurality of limiting holes 1 304 formed therein, and the plurality of limiting holes 1 304 are evenly arranged along the length of the plug-in rod 301. The receiving tube 2 has a limiting hole 201 corresponding to the limiting hole 1 304.

The limiting pin 9 limits the plug-in rod 301. By adjusting the distance between the two crossbars 3, it is suitable for hoisting insulated pipes 6 of different lengths to be hoisted.

[0044] There are three connecting rods 301. The connecting rods 301 on both sides are longer, and the middle connecting rod 301 is shorter. A limiting hole 304 is opened on the middle connecting rod 301. The middle connecting rods 301 of the two cross bars 3 are located in a receiving tube 2, and the connecting rods 301 on both sides of the two cross bars 3 are staggered.

[0045] In other embodiments, the crossbar 3 is movably connected to the frame 1 through a slide rail and slider 5 assembly.

[0046] In some embodiments, the slider 5 is movably connected to the crossbar 3 via a vertical rod 502. The slider 5 is fixedly provided with a vertical rod 502 at its lower end. The diameter of the vertical rod 502 matches the width of the slider 5, facilitating removal and installation of the slider 5. The crossbar 3 is provided with a strip-shaped hole 303 that matches the vertical rod 502, and the vertical rod 502 is installed inside the strip-shaped hole 303. A connecting seat 503 is fixedly provided at the lower end of the vertical rod 502, and a connecting hole is formed in the connecting seat 503. The connecting seat 503 is connected to the connecting rope 7 via a connecting member 8. The connecting member 8 includes two connecting plates, which are connected by a connecting shaft 801. There are two connecting shafts 801, one connected to each end of the connecting plate.

When the crossbar 3 needs to be moved, the slider 5 is moved upward until the stopper rod 302 is disengaged from the through-hole 501. Moving the slider 5 changes the distance between the two sliders 5, thereby adjusting the distance between the two hooks 4. This is suitable for hanging insulated pipes 6 with different outer diameters.

[0047] In other embodiments, the slider 5 is movably connected to the crossbar 3 via a plug-in rod 301 .

A threaded hole corresponding to the rubber pad 404 is opened on the vertical plate with the mounting shaft 402, and an adjusting bolt 403 is threadedly connected to the threaded hole. A handle 405 is fixed on the upper end of the adjusting bolt 403, and a rubber block 406 is provided on the lower end of the adjusting bolt 403. The rubber pad 404 and the rubber block 406 prevent scratches on the insulated pipe 6 to be hoisted. By rotating the adjusting bolt 403, the distance between the rubber block 406 and the rubber pad 404 can be adjusted, which is suitable for insulated pipes with different wall thicknesses.

[0049] In other embodiments, the hook 4 comprises a U-shaped plate ordinary hook.

[0050] Working process:

[0051] Adjust the distance between the two cross bars 3 according to the length of the insulated pipe 6 to be hoisted, adjust the distance between the two sliders 5 according to the outer diameter of the core pipe of the insulated pipe 6 to be hoisted, adjust the distance between the rubber block 406 and the rubber pad 404 according to the wall thickness of the core pipe of the insulated pipe 6 to be hoisted, and then align the opening of the U-shaped plate with the side wall of the core pipe and insert it. Multiple insulated pipes 6 to be hoisted can be hoisted at one time. By adjusting the distance between adjacent sliders 5, the distance between adjacent adjustment sliders 5 is greater than the outer diameter of the insulated pipe 6 to be hoisted, which can prevent the middle insulated pipe from being squeezed during the hoisting process, thereby preventing damage to the insulation layer of the insulation pipe.
