DETAILED DESCRIPTION

[0023] See also Figure 1-4 , a hanger for maintenance of electromechanical equipment for urban rail transit, comprising a support frame 1, wherein a limiting mechanism 2 is arranged inside the support frame 1;

[0024] The limiting mechanism 2 includes two support seats 201, each of which is slidably connected to the inside of the support frame 1. Two adjustment blocks 3 are slidably connected to the inside of each support seat 201. The front and back of the support frame 1 are fixedly connected to two connecting blocks 4. Each adjusting block 3 is rotatably connected to the inside of the connecting block 4. By utilizing the cooperation between the adjusting block 3 and the connecting block 4, the height of the support frame 1 can be conveniently adjusted. The adjusting block 3 can exert force on the connecting block 4 during the movement, thereby driving the support frame 1 to rise, thereby increasing the functionality of the device.

[0025] Each adjusting block 3 is slidably connected to two fixing bolts 6 inside, and each support seat 201 has two groups of threaded holes 5 arranged at equal distances on the upper surface. Each group of fixing bolts 6 is threadedly connected to one group of threaded holes 5. The fixing bolts 6 can effectively fix the position of the adjusting block 3 after adjustment, avoiding the situation where the support frame 1 drops due to the adjustment block 3 moving again after adjustment, thereby increasing safety when using the device.

[0026] Two support blocks 202 are fixedly connected to the upper surface of the support frame 1, and the interiors of the two support blocks 202 are rotatably connected together with a wire rope assembly 204. The right end of the wire rope assembly 204 is fixedly connected to a servo motor 203, and the bottom surface of the servo motor 203 is fixedly connected to the upper surface of the support frame 1. The bottom surface of each support seat 201 is fixedly connected to two connecting columns 7, and the interior of each connecting column 7 is rotatably connected to a moving wheel 8. By utilizing the cooperation of the connecting column 7 and the moving wheel 8, the support seat 201 can be moved or changed in direction while moving, which can be achieved through the connection relationship between the connecting column 7 and the moving wheel 8.

[0027] The bottom end of the wire rope assembly 204 passes through the support frame 1 and is fixedly connected to a hook 205. The outer surface of the wire rope assembly 204 is fixedly connected to a limiting column 206. The outer surface of the wire rope assembly 204 is sleeved with an auxiliary bearing 9, and the auxiliary bearing 9 is embedded in one of the support blocks 202. The auxiliary bearing 9 can effectively reduce the friction generated by the wire rope assembly 204 during rotation, making the wire rope assembly 204 more sensitive during rotation, and can also reduce the wear of the wire rope assembly 204 and increase the service life of the wire rope assembly 204.

[0028] Two auxiliary blocks 207 are fixedly connected to the inner wall of the support frame 1, and a rotating motor 208 is fixedly connected to the upper surface of each auxiliary block 207. The output end of the power of each rotating motor 208 is fixedly connected to a threaded rod 209. The bottom end of each threaded rod 209 penetrates the auxiliary block 207 and extends to the interior of the auxiliary block 207. The outer surface of each threaded rod 209 is sleeved with a rotating bearing 10, and each rotating bearing 10 is embedded in the interior of the auxiliary block 207. The rotating bearing 10 can effectively reduce the friction generated by the threaded rod 209 during rotation, making the threaded rod 209 more sensitive during rotation. At the same time, it can also reduce the wear rate of the threaded rod 209 and increase the service life of the threaded rod 209.

[0029] The outer surface of each threaded rod 209 is threadedly connected with a moving block 210, and each moving block 210 is slidably connected to the inside of the auxiliary block 207. The side of the two moving blocks 210 that are close to each other is fixedly connected with a firm block 211, and the inner wall of each firm block 211 is fixedly connected with a hydraulic rod 212. The telescopic end of each hydraulic rod 212 is fixedly connected to a limiting tube 213. The side of the two moving blocks 210 that are away from each other is fixedly connected with a stabilizing block 11, and each stabilizing block 11 is slidably connected to the inside of the auxiliary block 207. The stabilizing block 11 can move simultaneously with the moving block 210, and use its own friction with the auxiliary block 207 during the movement to improve the stability of the moving block 210 during movement, thereby increasing the stability of the device.

[0030] The working principle of the utility model is as follows: when in use, firstly, the servo motor 203, the rotating motor 208 and the hydraulic rod 212 are powered on, and the support seat 201 and the support frame 1 are moved to a suitable position through the cooperation of the connecting column 7 and the moving wheel 8. When it is necessary to lift the electromechanical equipment, the servo motor 203 is started, and then the wire rope assembly 204 is rotated forward, so that the hook 205 is lowered, and then the hook 205 passes through the electromechanical equipment to be lifted, and then the wire rope assembly 204 is reversed by the servo motor 203 to make the hook 205 rise. When it is necessary to limit the electromechanical equipment, the two rotating motors 208 are started, and then the two threaded rods 209 are rotated forward or reversed, so that the moving block 210 drives the fixing block 211 inside the auxiliary block 207 Move up and down, so that the limit tube 213 moves at the same time. When the limit tube 213 is parallel to the limit column 206, the rotation of the motor 208 can be stopped, and then the hydraulic rod 212 is started, so that the limit tube 213 moves outward, and then the limit column 206 is wrapped and the position of the limit column 206 is limited, thereby limiting the position of the electromechanical equipment to prevent the electromechanical equipment from shaking during maintenance, effectively increasing the safety of the device when in use, when it is necessary to adjust the height of the support frame 1, rotate the two fixing bolts 6 to separate them from the adjusting block 3, and then move the adjusting block 3, so that the connecting block 4 drives the support frame 1 to rise, and when it is adjusted to the appropriate position, the fixing bolts 6 are screwed into one of the sets of threaded holes 5, which effectively improves the use effect of the device.

[0031] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
