AI Technical Summary

Technical Problem

Traditional methods of disassembling pins, such as gas cutting and hammering, can damage the pin and surrounding components, resulting in high spare parts consumption and making them unusable after repair.

Method used

The system employs a combination of a lifting platform, connecting components, and hydraulic cylinders. The hydraulic system drives the scissor lift and connecting components to achieve non-destructive disassembly of the pin shaft. Detachable connectors and limit cylinders ensure the stability and precision of the disassembly process.

Benefits of technology

It enables the disassembly of the pin shaft without damage or with minimal damage, reduces the frequency of spare parts replacement, improves disassembly efficiency and equipment maintenance efficiency, and reduces maintenance costs.

Abstract

This application discloses a disassembly device for disassembling the pin of a sector section of a continuous casting machine. The sector section includes an upper frame and a lower frame, which are hinged together by a pin parallel to the casting roll of the continuous casting machine. The disassembly device includes: a lifting vehicle, comprising a vehicle body, a hydraulic station, and a scissor lift, both of which are mounted on the vehicle body; a hydraulic cylinder with a piston rod, the cylinder body of which is mounted on the lifting platform of the scissor lift; the hydraulic cylinder is connected to the hydraulic station via an oil pipe; and a connecting assembly, including a first connector and a second connector, which are detachably connected. The first connector is connected to the piston rod, and the second connector is welded to the end face of the pin. The hydraulic station, the scissor lift, and the pin are arranged sequentially along the axial direction of the pin, with the end of the piston rod away from the cylinder body extending out of the lifting vehicle along the axial direction of the pin.
