[0030] An upper support frame 4, the upper support frame 4 is fixedly connected to the adjacent ends of the two triangular support frames 2;

[0031] The lifting mechanism includes a slide rail 6, a rope 7, a hook 8, a cross slot 9, a transmission box 10, a fixed plate 13, a rope winding wheel 14, a servo motor 18, a cross slider 19, two springs 21 and two limit rods 22, wherein the slide rail 6 is provided with two groups, the two slide rails 6 are fixedly connected to the surface of the upper support frame 4, the fixed plate 13 is fixedly connected to one side end of one of the triangular support frames 2, the transmission box 10 is arranged on the lower side of the upper support frame 4, the cross slider 19 is fixedly connected to one side end of the transmission box 10, the cross slot 9 is opened at one side end of one of the triangular support frames 2, and the cross slider 19 is fixedly connected to one side end of the transmission box 10. It is slidably connected in the cross groove 9, the rope winding wheel 14 is arranged in the fixed plate 13, the servo motor 18 is fixedly connected to one side end of the fixed plate 13, the rope winding wheel 14 is fixedly connected to the output shaft of the servo motor 18, the rope 7 is located in the two slide rails 6, the hook 8 is fixedly connected to one side end of the rope 7, the slide rail 6 is wound around the surface of the rope winding wheel 14, the two limit rods 22 are fixedly connected between the upper and lower inner walls of the cross groove 9, the two springs 21 are respectively sleeved on the circumferential surfaces of the two limit rods 22, and the two springs 21 are fixedly connected to the close ends of the cross slider 19 and the lower inner wall of the cross groove 9.

[0032] In a specific embodiment of the utility model, there are four groups of springs 21 and limit rods 22 in the device, which are used in pairs. There are two groups of cross sliders 19 and cross slots 9 to maintain the stability of the transmission box 10. The transmission box 10 is bound to the hook 8 by a wire rope. The rope 7 can drive the transmission box 10 to move up and down. A roller is provided inside the slide rail 6. The transmission rope 7 through the slide rail 6 can lift the transmission box 10 to play a role in positioning and steering. A person stands in the transmission box 10 and starts the servo motor 18. The rope winding wheel 14 starts to work and wraps the rope 7 around its surface. When the transmission box 10 moves, the cross slider 19 moves upward in the cross slot 9 to play a role in limiting.

When the transmission box 10 descends, its weight will exert pressure on the spring 21, and the transmission box 10 automatically descends to prevent the transmission box 10 from shaking, maintaining its stable movement and safety, and controlling the winding of the rope 7 to make the transmission box 10 slide up and down. When the predetermined lifting height is reached or a stop command is received, the servo motor 18 stops working, and the rope winding wheel 14 slows down until it stops rotating. The transmission box 10 maintains the current position, ensuring the safety of personnel and equipment, facilitating personnel's high-altitude work, and at the same time improving stability, preventing it from shaking, and protecting personnel safety.

[0033] For details, please refer to Figure 5A bottom plate 15 is fixedly connected to the adjacent ends of the two bottom frames 1 , and four counterweights 16 are fixedly connected to the upper ends of the bottom plates 15 .

[0034] In this embodiment: the bottom plate 15 is used for placement, and the counterweight block 16 is used to provide additional stability when the transmission box 10 is working, so that during the lifting process, the weight of the counterweight block 16 helps to balance the center of gravity, reduce shaking, and ensure the stability of the lifting process.

[0035] For details, please refer to Figure 5 A second hollow groove 20 is formed at one side end of the two triangular support frames 2 , and support columns 17 are provided in the two second hollow grooves 20 . The transmission box 10 is located at the upper end of the support columns 17 .

[0036] In this embodiment: two support columns 17 are provided, which are inserted into the second hollow groove 20 to support the transmission box 10. The transmission box 10 is located at the upper end of the support columns 17. This arrangement can ensure that the transmission box 10 is in a stable and safe position when stopped.

[0037] For details, please refer to Figure 1-Figure 3 The lower ends of the two base frames 1 are fixedly connected with universal wheels 3, and the universal wheels 3 are provided with brake components.

[0038] In this embodiment: the universal wheel 3 has a freely rotatable axle, and the base frame 1 moves along different angles without changing the direction. A brake assembly is provided inside the universal wheel 3 to provide a locking effect when it is necessary to limit the position of the base frame 1.

[0039] For details, please refer to Figure 1 , the tripod support frame 2 is a solid core structure.

[0040] In this embodiment: the triangular support frame 2 adopts a solid core structure to provide higher structural strength and stability, ensuring that the triangular support frame 2 will not be deformed or damaged when bearing weight and external loads.

[0041] For details, please refer to Figure 1-Figure 2 A support plate 5 is fixedly connected to the adjacent ends of the upper support frame 4 and the triangular support frame 2 .

[0042] In this embodiment: the support plate 5 can provide a supporting effect, so that the connection between the upper support frame 4 and the triangular support frame 2 is stable and does not break, thereby playing a protective role.

[0043] For details, please refer to Figure 1 A first hollow groove 11 is formed on the lower inner wall of the transmission box 10 .

[0044] In this embodiment, the first hollow groove 11 can be used to reduce the weight of the transmission box 10, and the dust in the transmission box 10 can be cleaned out through the first hollow groove 11, thereby improving convenience.

[0045] For details, please refer to Figure 1-Figure 5 A plurality of trapezoidal support frames 12 are fixedly connected to the adjacent ends of the two triangular support frames 2, and the material of the trapezoidal support frames 12 is stainless steel.

[0046] In this embodiment: a plurality of trapezoidal support frames 12 increase the stability and load-bearing capacity of the lifting equipment. The trapezoidal support frames 12 are made of stainless steel to improve the corrosion resistance and durability of the support frames. The trapezoidal support frames 12 can also be used as ladders to facilitate personnel to enter the transmission box 10.

[0047] The working principle and use process of the utility model are as follows: after the servo motor 18 is started, the rope winding wheel 14 starts to work. After the rope 7 is wound, the transmission box 10 moves upward. At the same time, the elastic force of the spring 21 will be released during the rising process, resulting in a slight up and down amplitude to prevent the equipment from breaking and play a buffering effect. The limit rod 22 is used to limit the cross slider 19, and the limit of the cross slider 19 is strengthened, so that the transmission box 10 can rise stably and will not shake left and right when rising or falling. When the transmission box 10 descends, its weight will put pressure on the spring 21, and the transmission box 10 automatically descends. When the predetermined lifting height is reached or a stop command is received, the servo motor 18 stops working, the rope winding wheel 14 slows down until it stops rotating, and the transmission box 10 maintains the current position to ensure the safety of personnel and equipment and facilitate personnel to work at high altitude. At any time, if an emergency occurs, the operator can immediately cut off the power supply, the servo motor 18 stops working immediately, the rope winding wheel 14 stops rotating, and the lifting mechanism maintains the current state to ensure the safety of personnel and equipment.

[0048] The electronic components and modules used in the content of this utility model can all be parts commonly used in the market that can realize the specific functions in this case, and the specific models and sizes can be selected and adjusted according to actual needs.
