The transfer platform 2 is also provided with a handrail 22 for facilitating the movement of the push device.

[0027] The lifting device 3 is arranged between the mobile mechanism 1 and the transfer platform 2 to lift the transfer platform 2. The lifting device 3 includes a folding bracket 31 connected between the mobile mechanism 1 and the transfer platform 2 and a hydraulic component 32 driving the folding bracket 31 to extend or shorten. Specifically, the mobile mechanism 1 is a plurality of universal wheels arranged at the bottom of the lifting device 3.

[0028] The clamping mechanism 4 is arranged on the transfer platform 2 to clamp the circuit breaker, and includes a fixed block 41, a sliding block 42, and a driving assembly 43. The fixed block 41 is arranged on the right side of the transfer platform 2; the sliding block 42 is arranged on the left side of the transfer platform 2 relative to the fixed block 41, and moves back and forth in the direction of approaching or moving away from the fixed block 41, and a clamping space for the circuit breaker to enter and clamp is formed between the two; the driving assembly 43 is connected to the sliding block 42 and drives it to move back and forth so that the circuit breaker is clamped between the fixed block 41 and the sliding block 42. The circuit breaker is clamped on the transfer platform 2 to improve the safety of the circuit breaker during transportation.

[0029] The driving assembly 43 includes a rack 431, a ratchet 432, a cam 433 and a driving motor 434. The rack 431 is connected to the sliding block 42 perpendicular to the moving direction of the circuit breaker and can move with it on the transfer platform 2; the ratchet 432 cooperates with the rack 431 to limit the unidirectional movement of the rack 431; the cam 433 is rotatably arranged on the transfer platform 2, and the ratchet 432 is rotatably connected to the cam 433; the driving motor 434 is connected to the cam 433 and drives it to rotate. The driving motor 434 is eccentrically connected to the ratchet 432 on the cam 433, driving the ratchet 432 to reciprocate on the rack 431 to drive the rack 431 to slide in one direction. Specifically, the tooth shape of the rack 431 is inclined in the right direction, one end of the ratchet 432 is arranged on the cam 433, and the other end is inclined to the left and clamped on the rack 431, which can contact the right side of the tooth shape of the rack 431 and push the rack 431 to slide. Furthermore, the transfer platform 2 is provided with a mounting platform 435 protruding outward, and a rack 431, a pawl 432, a cam 433 and a driving motor 434 are arranged on the mounting platform 435. The sliding block 42 moves on the mounting platform 435 and is connected to the rack 431. The other end extends to the transfer platform 2. The mounting platform 435 is provided with a plurality of buttons 436 for controlling the start and stop of the driving motor 434.

[0030] Two laser emitters 5 are provided, which are respectively arranged on the fixed block 41 and the sliding block 42, and arranged along the moving direction of the circuit breaker. The laser is irradiated in the horizontal direction to locate the width of the clamping space so as to be aligned with the position of the circuit breaker installation cabinet. Irradiating the circuit breaker installation cabinet to determine the position of the circuit breaker and align it with the installation position makes it easier to push the circuit breaker into the power cabinet, which can effectively improve work efficiency.

[0031] The observation mechanism 6 is located near the side of the sliding block 42 and is arranged between the edge of the transfer platform 2 and the sliding block 42. The observation mechanism 6 includes a support rod 61 and a reflector 62. The support rod 61 is arranged vertically on the transfer platform 2; the reflector 62 is arranged on the support rod 61 and the mirror surface is arranged perpendicular to the moving direction of the circuit breaker and the mirror surface faces the inner side of the transfer platform 2. When the circuit breaker needs to be installed in the power cabinet, the observation mechanism 6 allows the staff to observe the relative position of the operating trolley and the circuit breaker installation cabinet and the position of the laser emitter 5 when operating the operating trolley to move, so as to avoid the problem of blocking the field of vision due to the large size of the circuit breaker, so that the laser emitter 5 needs to be repeatedly confirmed when adjusting the position of the operating trolley.

[0032] The limit mechanism 7 is arranged on the transfer platform 2 and is located on the same side of the transfer platform 2 as the laser emitter 5, and includes a proximity switch 71 arranged opposite to the moving direction of the circuit breaker and a warning light 72 connected to the proximity switch 71 and lit according to the feedback signal of the proximity switch 71. The laser emitter 5 is in the same direction as the proximity switch 71. By monitoring the position of the circuit breaker through the proximity switch 71, even if a single person is operating, it is possible to quickly know whether the circuit breaker has been completely moved to the transfer platform 2, thereby avoiding accidents caused by the circuit breaker not being completely moved to the transfer platform 2.

[0033] When disassembling the circuit breaker, first disassemble the connection between the circuit breaker and the power cabinet, then move the operating trolley to the front of the power cabinet, align the fixed block 41 on the right side with the right side of the power cabinet outlet and bring the operating trolley close to the power cabinet, then pull the circuit breaker out of the power cabinet and move it to the operating trolley. The position of the circuit breaker is monitored by the proximity switch 71. When the circuit breaker is against the proximity switch 71, it means that it has been completely moved to the transfer platform 2. Then operate the button 436 on the mounting platform 435 to control the drive motor 434 to work, drive the sliding block 42 to move in the direction close to the circuit breaker until it clamps the circuit breaker with the fixed block 41. At this time, the circuit breaker is fixed and can be transferred to other places for maintenance, inspection or replacement.

[0034] After maintenance, inspection or replacement of the circuit breaker, the circuit breaker needs to be reinstalled into the power cabinet. At this time, the circuit breaker is transported to the front of the power cabinet by the operating trolley, and the laser transmitter 5 is turned on. The staff pushes the operating trolley to move behind the operating trolley while observing the indicator mark of the laser transmitter 5 on the power cabinet through the observation mechanism 6, adjusts the operating trolley to a suitable position and pushes the operating trolley close to the power cabinet to align the circuit breaker with the power cabinet. At this time, the driving sliding block 42 is away from the circuit breaker, and the circuit breaker can be pushed into the power cabinet for installation. The installation is efficient and fast, and there is no need to repeatedly correct the position of the operating trolley. Even one person can quickly complete the transportation and installation of the circuit breaker, which is very practical.

[0035] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of implementation of the present utility model. That is, equivalent changes and modifications made according to the scope of the patent application of the present utility model and the contents of the specification should still fall within the scope covered by the patent of the present utility model.
