AI Technical Summary
The existing circuit breakers are installed at a high position, requiring the cover to be removed before maintenance or installation can be carried out, which increases the difficulty and fatigue risk of working at height and affects work efficiency.
Design a device for removing the end cover of a circuit breaker, including an end seat assembly, a main telescopic hydraulic cylinder, a moving seat assembly, and a cover removal assembly. Through coordinated work, it can achieve mechanized disassembly operations at long distances and multiple angles. It uses a suction cup to provide a stable support base, ensuring the overall stability and safety of the device.
It achieves safety and efficiency in high-altitude operations, reduces the difficulty and risk of falls, improves work efficiency, and ensures disassembly accuracy and stability.
