Rail-mounted circuit breaker operation trolley

Abstract

The invention discloses a rail-mounted circuit breaker operation trolley, which is characterized in that a transfer trolley is firstly aligned with an inlet of a circuit breaker chamber, then the transfer trolley transfers out two rails located in sliding grooves, the rails are pulled to the needed extending length, the rails are in lap joint with a bottom plate of the circuit breaker chamber, thetwo rails are adjusted to be aligned with walking wheels on a circuit breaker, and then the circuit breaker is dragged to an object bearing table along the rails. Firstly, the object bearing table and the bottom plate of the circuit breaker chamber are connected into a load bearing main body through the two rails, when the circuit breaker is dragged to the object bearing table of the transfer trolley from the circuit breaker chamber, the transfer trolley is stressed uniformly, the transfer trolley is stable and not prone to overturning, and the carrying efficiency is improved; and secondly, the distance between the two rails can be adjusted to adapt to circuit breakers of various specifications.

Description

technical field [0001] The invention generally relates to the technical field of electric power maintenance, and in particular to a trolley for operating a rail-type circuit breaker. Background technique [0002] Cart type circuit breakers are widely used in power grid equipment such as substations. There are many types and complex brands. Although they are roughly the same in principle, there are differences in their size and structure. Most of the tools for transfer and operation of circuit breakers in the existing market are It is a transfer trolley, with a fixed frame and a transfer platform. When the circuit breaker needs to exit and enter the circuit breaker room, the circuit breaker needs to be pulled out manually, and transferred to the transfer trolley with the rollers on the chassis of the circuit breaker. During the transfer process, the transfer trolley needs to be aligned with the entrance of the circuit breaker room. When the circuit breaker is dragged from the...

[0002] Cart type circuit breakers are widely used in power grid equipment such as substations. There are many types and complex brands. Although they are roughly the same in principle, there are differences in their size and structure. Most of the tools for transfer and operation of circuit breakers in the existing market are It is a transfer trolley, with a fixed frame and a transfer platform. When the circuit breaker needs to exit and enter the circuit breaker room, the circuit breaker needs to be pulled out manually, and transferred to the transfer trolley with the rollers on the chassis of the circuit breaker. In the process of transfer, it is necessary to align the transfer trolley with the entrance of the circuit breaker room. When dragging the circuit breaker from the circuit breaker room to the transfer trolley, misalignment and the overturning of the trolley are prone to occur.
