Abstract

The invention provides a circuit breaker energy storage spring auxiliary dismounting and mounting device, and solves the technical problems that in the prior art, when an energy storage spring is dismounted and mounted, at least two workers are needed to cooperate with each other for completion, and the operation is inconvenient. The device comprises a connecting arm, an upper fixing device and alower fixing device, wherein the upper fixing device and the lower fixing device are used for fixing the upper end and the lower end of the energy storage spring respectively, the upper fixing deviceand the lower fixing device are both connected to the connecting arm, and the distance between the upper fixing device and the lower fixing device is adaptive to the height of the energy storage spring. The device is used for dismounting and mounting of the circuit breaker energy storage spring, only one worker is needed for completion, and the device is convenient and safe.

Description

technical field [0001] The invention relates to an auxiliary assembly and disassembly device, in particular to an auxiliary assembly and disassembly device for an energy storage spring of a circuit breaker. Background technique [0002] Common faults of circuit breakers include burnt closing coil and energy storage motor damage. When encountering these faults, it is often necessary to replace the damaged parts. When replacing parts, it is almost necessary to remove the energy storage spring. Replacement of parts. The installation of the energy storage spring is to connect its upper and lower ends to the circuit breaker respectively, and the energy storage spring is always in a stretched state; when dismantling, it is also removed from the upper and lower ends of the energy storage spring; When storing the energy spring, because the energy storage spring is in a stretched state, the moment the elastic force is released when it is removed, it may pinch the hands of the staff ...
