Frame device for lifting and transporting tunneling head-on temporary bracket, and operation method

Abstract

The invention particularly discloses a frame device for lifting and transporting a tunneling head-on temporary bracket, and an operation method. The frame device comprises a hydraulic self-moving system, a frame loading trolley for moving the temporary bracket back and forth, and a bracket lifting assistance system for lifting the temporary bracket, wherein the frame loading trolley is arranged on a bracket at the top of the hydraulic self-moving system, and driven by a traction system; the bracket lifting assistance system is fixed on the bracket at the top of the hydraulic self-moving system and on a slide shoe base at the bottom of the hydraulic self-moving system; a main function of the hydraulic self-moving system is that the device moves forwards with roadway tunneling; the frame loading trolley and the traction system move the temporary bracket from the back of a machine to the front of the machine; and the bracket lifting assistance system provides assistance for lifting of the temporary bracket. According to the device, an enough space is arranged at the lower part of the device to satisfy operation of the tunneling machine and operators of the tunneling machine, and layout of ventilation, dust removal and pipeline facilities, so that exposure operation of roadway support is avoided.

Description

[0001] technical field [0002] The invention relates to a frame device and an operation method used for the lifting and moving of a head-on temporary support for excavation. Background technique [0003] Support is required after the excavation of the underground project. In order to protect the surrounding rock from falling and collapsing during the support operation, temporary support must be provided first so that the operators can work under reliable support. [0004] There are mainly five types of temporary support methods for existing underground engineering excavation construction: [0005] 1. The traditional temporary support methods include suspension rings, steel pipes (or rails, profiled steels), etc., that is, through the front channel steel pipes, etc., add roof protection materials on them, and wedge between the rear end of the steel pipes and the roof, and the The front end is raised to protect the roof. [0006] 2. Airborne joist roof protection method of ...

AI Technical Summary

Problems solved by technology

The device cooperates with the matching temporary support, which solves the problem of the front erection, rear retraction, forward movement to the front of the machine and erection of the temporary support in the excavation work, as well as the parallel operation problem of the permanent support of the roadway and the cutting of the roadheader.
