Description

Technical Field

[0001] The invention relates to a switch cabinet circuit breaker transfer trolley, belonging to the technical field of supporting production, maintenance and installation of substation switch cabinet control equipment. Background Art

[0002] The substation switch cabinet is a high-voltage heavy-duty control equipment. During the switching operation of the 10kV line power outage in the station, the circuit breaker needs to be manually pulled from the inside of the cabinet to the outside of the cabinet. After the maintenance work is completed outside the cabinet, it is pushed from the outside of the cabinet to the inside of the cabinet for power transmission. After the existing trolley pulls the circuit breaker onto the maintenance vehicle, the circuit breaker must be transferred together with the trolley if it is to be transferred. When encountering on-site operations such as 10kV bus power outages, a large number of circuit breakers need to be pulled outside the cabinet, so a large number of trolleys need to be prepared. And because the circuit breaker is heavy and has a high center of gravity, there is a risk of tipping over when the road surface is uneven during the transfer process.

[0003] There are two different widths of 10kv circuit breakers with different sizes and weights. When replacing the circuit breakers, two different trolleys are needed for transfer, and the transfer process is relatively troublesome.

[0004] The existing traditional switch cabinet circuit breaker transfer cart simply realizes the transfer of circuit breakers. The circuit breaker needs to be removed from the cart by other auxiliary tools to be unloaded from the ground. In addition, the existing cart is fixed to the tray as a whole, and there is no function to adjust the position of the tray separately. When installing the circuit breaker, it is extremely difficult to align the circuit breaker with the switch cabinet because it is too heavy. Summary of the invention

[0005] According to the problem described in the background, the problem to be solved by the present invention is: to provide a switch cabinet circuit breaker transfer trolley, which solves the problem proposed in the above technical background that the existing transfer trolley has no lifting structure, cannot be placed on the ground and cannot be taken out, cannot be adjusted horizontally, has a risk of tipping over, is difficult to align, and in the process of pulling out the circuit breaker for loading, the locking hook on the trolley tray will detach from the switch cabinet, causing the trolley to back up and not be able to pull up the tray, and there is a risk of the circuit breaker falling to the ground.

[0058] The pallet is positioned and installed on the trolley body through the pallet sleeve and the support shaft, and the overall transfer trolley is aligned with the switch cabinet. The motor 201 is operated to adjust the height position of the lifting support platform 3, and the horizontal and height positions of the movable frame 311 and the support shaft 309 are fine-tuned so that the positioning pin 404 of the pallet is inserted into the special hole on the switch cabinet. The anti-mistaken lock tongue hanging mechanism 5 is operated to make the lock tongue 507 effectively hang with the locking hole of the switch cabinet, and the circuit breaker is pulled out from the front to the pallet and fixed. The anti-mistaken lock tongue hanging mechanism 5 is operated to detach from the switch cabinet. The motor 201 is reversed to lower the pallet to prevent instability due to excessive center of gravity, and the transfer trolley is pushed to the designated position. The circuit breaker and the pallet are placed on the ground together, and the transfer trolley is withdrawn.

[0059] Circuit breaker installation process:

[0060] The transfer trolley carrying the circuit breaker rises to the approximate position of the switch cabinet, and fine-tunes the horizontal and height positions of the movable frame 311 and the support shaft 309. After alignment, the trolley is pushed forward again so that the positioning pin 404 of the tray is inserted into the special hole on the switch cabinet, and the anti-mistake lock tongue hanging mechanism 5 is operated to effectively hang the lock tongue 507 with the locking hole of the switch cabinet, and then the circuit breaker is pushed into the switch cabinet, and the trolley is pushed out to complete the transfer of the circuit breaker.
