[0002] In actual production, since some production unit processing equipment is relatively tall and large, when maintaining and replacing mechanical parts of mechanical equipment at high altitude, maintenance personnel need to perform high-altitude hoisting operations, which are difficult and dangerous. In cold rolling pickling and rolling units, continuous annealing units, and galvanizing units, the height of larger equipment such as rolling mills, temper mills, and skin pass mills reaches more than ten meters. It is very difficult to maintain and replace the mechanical parts at the top of these equipment. Maintenance personnel need to work at high altitude several meters above the ground. Due to the lack of a standing place and working suspended in the air, problems such as great operation difficulty, high danger, and low efficiency are caused. To solve the above problems, it is necessary to design a convenient, simple-structured, economical and practical tool mainly used for disassembling and assembling parts at high altitude of rolling mills, temper mills, and skin pass mills in production units.

[0014] In order to make the purposes, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments. Obviously, the described embodiments are a small part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0015] A tool for conveniently disassembling and assembling parts at high altitudes, comprising a hydraulic jack, a working platform 1, support rods 4 and cross braces 5. The hydraulic jack is fixedly installed on the working platform 1. The hydraulic jack includes a hydraulic lifting column 3, a hydraulic jack controller 2 and hydraulic oil pipes 6. The hydraulic jack controller 2 is connected to the hydraulic lifting column 3 through the hydraulic oil pipes 6. Four support rods 4 are provided under the working platform 1, which are respectively fixed at the four corners of the bottom surface of the working platform 1, perpendicular to and firmly connected to the lower surface of the working platform 1. Cross braces 5 are arranged between the support rods 4. The number of cross braces 5 is more than one. The cross braces 5 are vertically connected to the support rods 4 to connect the support rods 4 into one body.

[0016] The working platform 1 is a rectangular flat plate made of high-strength steel plate.

[0017] The bottom surface of the hydraulic lifting column 3 is provided with a magnetic attraction structure, and the hydraulic lifting column 3 is adsorbed at any position on the upper surface of the working platform 1 through the magnetic attraction structure.

[0018] Each support rod 4 is composed of more than one section of high-strength aluminum pipe. The diameter of each section of high-strength aluminum pipe gradually increases from top to bottom, and the upper section of high-strength aluminum pipe is inserted into the lower section of high-strength aluminum pipe. Each section of high-strength aluminum pipe is provided with a self-locking structure.

[0019] The cross braces 5 are square aluminum pipes. Each cross brace 5 is installed at the top of each section of high-strength aluminum pipe. Every four cross braces 5 form a group, which are horizontally aligned in sequence and connected end to end to form a rectangle.

[0020] In practical applications, the whole device is vertically placed on the ground or the equipment platform. The hydraulic lifting column 3 can be placed at any suitable position on the working platform 1 and adsorbed on the upper surface of the working platform 1 through the magnetic attraction structure to ensure that the hydraulic lifting column 3 does not slide during use. The support rods 4 are composed of multiple sections of high-strength aluminum pipes, and the upper section of high-strength aluminum pipe can be completely inserted into the lower section of high-strength aluminum pipe to realize the telescopic folding and adjustable length of the support rods. Each section of high-strength aluminum rod will be self-locked after being fully extended to ensure the fixed length of the support rods. In actual use, the total length of the support rods 4 can be adjusted according to needs. When adjusting, the four support rods 4 will keep synchronous telescoping to ensure the same length of the support rods 4. The cross braces 5 connected to the support rods 4 can ensure that the four support rods 4 are connected into one body, improving the strength and stability of the whole device. After the whole device is placed, the cross braces 5 will be used as a ladder for maintenance personnel. The maintenance personnel can climb up stepping on the cross braces 5 and stand on the cross braces 5 to operate the hydraulic jack controller 2 on the working platform 1 for maintenance operations.

[0021] An embodiment of the present utility model is as follows:

[0022] Such as Figure 3, when replacing the leveling mill screwdown device in the cold rolling continuous annealing unit, after adjusting the height of the support rod 4, place the device directly below the leveling mill screwdown device 8 inside the leveling mill frame 7. The maintenance personnel climb up by stepping on the support rod 4 and rely on the working platform 1 to disassemble and assemble the leveling mill screwdown device 8. Since the leveling mill screwdown device 8 is relatively heavy and cannot be lifted by manpower, the hydraulic lifting column 3 of the hydraulic jack on the working platform 1 can be used to lift and lower the leveling mill screwdown device 8, facilitating the quick completion of the disassembly and assembly work of the leveling mill screwdown device 8.
