AI Technical Summary

Technical Problem

The skip experiences severe wear during loading due to material impact on the bottom and during unloading, resulting in thinner side plates, reduced strength, and risks of wear and tear. Furthermore, the existing cushioning rubber has a short service life, and the joint bearings suffer from uneven stress, leading to a short service life and a large overall maintenance workload.

Method used

Design a movable straight-rail type bucket gate, which uses steel plates welded into a box-shaped bottom, installs buffer wood and wear-resistant lining plates, and uses spherical bearings to connect the lifting lugs and the pivot to improve impact resistance, and achieves stable movement of the bucket gate through the pivot and spherical bearings.

Benefits of technology

It improves the wear resistance and service life of the skip gate, reduces the failure rate, and enhances the stability and reliability of skip operation.

Abstract

The utility model belongs to the technical field of mine hoisting system equipment, concretely relates to a movable straight rail type skip door to solve the problem of the poor wear resistance of skip door side plate, short service life, high failure rate of skip door, poor stability and reliability of skip operation. The utility model is welded into the box type structure by the steel sheet, the grid shaped rib plate is welded at the bottom of the box, the deformation is ensured when the material impact, the buffer wood and the lining plate are successively installed at the top of the bottom, the skip door side plate is installed at both sides of the bottom, the lining plate and the skip door side plate are all the wear -resisting steel sheet of composite structure, the wear resistance is good, and the buffer wood plays a certain buffer reducing effect to the impact potential energy of the material, the utility model structure is simple, the impact resistance is good, makes the failure rate of skip door reduce, effectively improves the stability and reliability of skip operation.
