Embodiment Construction
[0021] Such as Figure 1~4 As shown, a transfer trolley for a circuit breaker in a central switch cabinet includes a frame 1, four casters 2 are provided on the bottom side of the frame 1, and a bracket for carrying a circuit breaker is provided in front of the frame 1 3. The vehicle frame 1 is provided with a lifting drive mechanism for moving the bracket 3 up and down. The lifting drive mechanism includes a steel wire rope 4, a fixed pulley 5, a winding wheel 6 and an automatic wire take-up device 11. The bracket 1 One side of the bracket is connected to the winding wheel 6 through a steel wire rope 4 around a certain pulley 5, and the other side of the bracket is connected to the automatic wire take-up device 11 through another steel wire rope 4 around another fixed pulley 5. 1 and bracket 3 is provided with a lifting guide mechanism. The following briefly introduces the existing automatic wire take-up device 11: when the winding wheel 6 retracts a steel wire rope 4, the a...

The invention relates to a central-positioned switch cabinet circuit breaker transfer cart, which comprises a cart frame; four foot wheels are arranged at the bottom side of the cart frame; a bracket used for bearing a circuit breaker is arranged in the front side of the bracket; one side of the bracket is connected with a winding wheel through a steel wire rope bypassing a fixed pulley; the winding wheel is driven by a hand crank or a motor to rotate; the other side of the bracket is connected with an automatic take-up device through another steel wire rope bypassing another fixed pulley; and a lifting guide mechanism is arranged between the cart frame and the bracket. The central-positioned switch cabinet circuit breaker transfer cart can be used for fast adjusting the height position of the circuit breaker through the vertically lifting bracket, thereby enabling the height position of the circuit breaker to be flush with the mounting position of the switch cabinet, the fast installation of the circuit breaker is favored, the labor intensity of installation personnel is reduced, and the mounting efficiency of the circuit breaker is improved.
Description
technical field [0001] The invention relates to a transfer trolley for a circuit breaker in a central switch cabinet. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions, and can close, carry and break current under abnormal circuit conditions within a specified time. Generally, after the circuit breaker is transported to the installation site, the circuit breaker is lifted to the transfer trolley by manual lifting or handling, and then the circuit breaker is sent into the switch cabinet by the transfer trolley, which has high labor intensity for the installers and high installation cost of the circuit breaker. High and low installation efficiency and other shortcomings. Contents of the invention [0003] The present invention makes improvements to the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the present invention is to...
