AI Technical Summary

Technical Problem

When loading and unloading heavy hydraulic support trucks, the operation is difficult and safe, and the loading and unloading process is not fast enough to meet the rapid loading and unloading needs of heavy hydraulic support above 80 tons.

Method used

A directional excitation shovel assembly mechanism of a hydraulic support truck is designed. By setting up an excitation box on the shovel plate, the excitation force is used to reduce the friction between the base of the hydraulic support and the shovel plate. Through the vibration absorber and chain lifting mechanism, the traction and excitation force of the vehicle are used to realize the shovel installation and self-unloading of the hydraulic support.

Benefits of technology

This technology reduces the operation difficulty of the hydraulic support loading and unloading process, improves the safety of the loading and unloading process, and realizes the rapid loading and unloading of heavy hydraulic support above 80 tons, meeting the rapid handling needs of heavy hydraulic support.

Abstract

The present invention provides a directional vibration shoveling mechanism for a hydraulic support transport vehicle for coal mines, which belongs to the technical field of underground transport vehicles in coal mines, and includes a shovel board, a boom, a vibration box, a vibration absorber and a chain lifting mechanism; the top of the boom is provided with a hinged piece for being hinged with the front part of a U-shaped frame, and the bottom end is hinged with the front end of the shovel board; the vibration box is provided on the boom, and is used to apply a vibration force to the boom and the shovel board; the vibration absorber is connected to the boom and the front part of the U-shaped frame, and is used to absorb the vibration force generated by the vibration box on the U-shaped frame, and at the same time limit the swing angle of the boom; two groups of chain lifting mechanisms are symmetrically arranged, including a lifting chain and a chain retracting assembly; the chain retracting assembly is arranged on the side wing of the U-shaped frame; the lifting chain passes through the side wing of the U-shaped frame, the bottom end is connected with the shovel board, and the top end is connected with the chain retracting assembly. The mechanism not only retains the advantage of the stable process of transporting the hydraulic support in the bottom-sealed shovel board bearing mode, but also reduces the operational difficulty of the hydraulic support loading and unloading process, and improves the safety of the loading and unloading process.
