AI Technical Summary

Technical Problem

Existing tunneling machines require a large amount of space to turn around inside the tunnel, have complex equipment structures, long construction periods, and high costs.

Method used

By laying lateral and turning tracks inside the tunnel and utilizing the existing tunneling machine receiving frame and hydraulic cylinders, and by modifying the receiving frame and installing guide blocks, the tunneling machine can be turned around inside the tunnel, simplifying the equipment structure and reducing reliance on additional power systems.

Benefits of technology

The ability to turn the tunneling machine around in confined spaces reduces construction costs, simplifies equipment structure, reduces reliance on large hoisting equipment, and improves construction efficiency.

Abstract

本发明属于掘进设备领域，具体提供一种掘进机调头方法及装置。该方法包括①在洞口处布置横移轨道，在横移轨道上设置接收架；②掘进机从第一线出洞后移走至接收架上，将接收架顶起，在接收架底部安装可沿横移轨道移动的横移导向块；③步进驱动接收架沿横移轨道移动，直至调头轨道上方；④将接收架顶起，拆除横移导向块，在接收架底部安装调头机构；⑤步进驱动接收架沿调头轨道移动调头；⑥将接收架顶起，安装横移导向块，步进驱动接收架沿横移轨道移动至第二线始发位。该装置用于实施上述方法。本发明基于现有的掘进机接收架进行改造，在洞室中铺设轨道，用简易的液压缸、导向块等驱动掘进机完成调头，降低成本。
