The sleeve 25 and the first screw 24 are slidably connected. A nut 214 is threadedly connected to the surface of the first screw 24, and the nut 214 is internally rotatably connected to the limiting block 213, the limit block 213 is fixedly connected to the sleeve 25, a rope 27 is wound around the surface of the sleeve 25, one end of the rope 27 is fixedly connected to the sleeve 25, the end of the rope 27 away from the sleeve 25 passes through the protective plate 22 and is fixedly connected to the hook 29, a limit ring 211 is arranged above the load-bearing platform 21, four hook rings 216 are symmetrically fixedly connected to the surface of the limit ring 211, the hook 29 is inserted into the inside of the hook ring 216, the surface of the hook 29 is fixedly connected to the limit pad 210, and the inside of the limit ring 211 is rotatably connected to the positioning ring 28.

[0036] In this embodiment: let the operator stand at the center of the upper surface of the load-bearing platform 21, pull the four hooks 29, so that the hooks 29 are hung inside the hook ring 216, and then apply force to the force rod 11, so that the lifting module 12 lifts the load-bearing platform 21 until it reaches an appropriate height. When the operator needs to turn his body, the positioning ring 28 will rotate inside the limiting ring 211 with the rotation of the body. When walking is required, the rope 27 on one side will be stretched, and the sleeve 25 connected to the rope 27 will rotate and slide on the surface of the first screw 24. The sleeve 25 will pull the nut 214, and the nut 214 will rotate on the surface of the first screw 24 until it is stretched to an appropriate length.

[0037] It should be noted that when use is completed, the hook 29 is taken out from the inside of the hook ring 216 , and when the rope 27 is retracted, the limiting pad 210 will be limited by the wear-resistant tube 212 to prevent the hook 29 from entering the inside of the limiting groove 23 .

[0038] Going further:

[0039] In an optional embodiment, a positioning groove 26 is formed on the surface of the sleeve 25 , and the rope 27 is positioned inside the positioning groove 26 .

[0040] In this embodiment, due to the limitation of the rope 27 by the positioning groove 26 , the positioning groove 26 will be pressed into the interior of the rope 27 to achieve the retraction of the rope 27 .

[0041] Going further:

[0042] In an optional embodiment, a wear-resistant cylinder 212 is sleeved on the surface of the rope 27 , the wear-resistant cylinder 212 is slidably connected to the rope 27 , and the wear-resistant cylinder 212 is fixedly connected to the protective plate 22 .

[0043] In this embodiment, when the rope 27 slides back and forth, the wear-resistant tube 212 has no edges or corners due to its shape, which reduces the wear of the rope 27 and prolongs its service life.

[0044] Going further:

[0045] In an optional embodiment, a spring volute 215 is disposed inside the limiting groove 23 , and two ends of the spring volute 215 are fixedly connected to the first screw rod 24 and the protective plate 22 , respectively.

[0046] In this embodiment: when the operator walks back to the original position, the spring volute 215 will drive the first screw 24 to rotate due to the elastic potential energy, the nut 214 threadedly connected to the first screw 24 will rotate to the original position, and the sleeve 25 rotatably connected to the nut 214 through the limit block 213 will be pulled.

[0047] Going further:

[0048] In an optional embodiment, it further includes a positioning component 3 disposed on the surface of the positioning ring 28;

[0049] The positioning assembly 3 includes four fixed blocks 31 evenly fixedly connected to the surface of the positioning ring 28, the internal thread of the fixed block 31 is connected to the second screw 33, one end of the second screw 33 is rotatably connected to the extrusion block 32, the extrusion block 32 and the fixed block 31 are slidably connected, and the adjacent sides of the four extrusion blocks 32 are fixedly connected to the sponge pads 34.

[0050] In this embodiment: the lifting device body 1 is used to put the positioning ring 28 on the operator, and then the second screw 33 is rotated. The second screw 33 will rotate inside the fixed block 31 and move toward the center of the positioning ring 28. The extrusion block 32 rotatably connected to the second screw 33 will slide on the surface of the fixed block 31 toward the center of the positioning ring 28 until the sponge pad 34 contacts the body of the worker, and the sponge pad 34 will be squeezed until the positioning ring 28 is limited on the operator.

[0051] The working principle and use process of the utility model are as follows: the lifting device body 1 needs to be used, the positioning ring 28 is placed on the operator, and then the second screw 33 is rotated. The second screw 33 will rotate inside the fixed block 31 and move toward the center of the positioning ring 28. The extrusion block 32 connected to the second screw 33 will slide on the surface of the fixed block 31 toward the center of the positioning ring 28 until the sponge pad 34 contacts the body of the worker, and the sponge pad 34 will be squeezed until the positioning ring 28 is limited on the operator. Let the operator stand at the center of the upper surface of the load-bearing platform 21, pull the four hooks 29, so that the hooks 29 are hung inside the hook ring 216, and then apply force to the force rod 11 to make the lifting module 12 lift the load-bearing platform 21 until it is raised to an appropriate height. When the operator needs to turn his body, the positioned ring 28 will rotate inside the limiting ring 211 with the rotation of the body. When walking is required, the rope 27 on one side will be stretched The sleeve 25 connected to the rope 27 will rotate and slide on the surface of the first screw 24, the sleeve 25 will pull the nut 214, and the nut 214 will rotate on the surface of the first screw 24 until it is stretched to a suitable length. When the operator walks back to the original position, the spring volute 215 will drive the first screw 24 to rotate due to elastic potential energy, and the nut 214 threadedly connected to the first screw 24 will rotate to the original position, and the sleeve 25 rotatably connected to the nut 214 through the limit block 213 will be pulled. Because the positioning groove 26 limits the rope 27, the positioning groove 26 will be pressed into the inside of the rope 27 to realize the retraction of the rope 27. When the rope 27 slides back and forth, the wear-resistant tube 212 has no edges and corners due to its shape, which reduces the wear of the rope 27 and extends its life. When use is completed, the hook 29 is taken out from the inside of the hook ring 216. When the rope 27 is retracted, the limiting pad 210 will be limited by the wear-resistant tube 212 to prevent the hook 29 from entering the inside of the limiting groove 23.
