Tunnel excavation staggered type supporting device

Abstract

The invention provides a tunnel excavation staggered type supporting device, which solves the problems in prior art of lagging supporting means, difficulty in moving, operation at a halt state, low efficiency and the like. The tunnel excavation staggered type supporting device comprises a hydraulic stand column as a support and a beam frame consisting of transverse beams and vertical beams. According to the technical main points, the beam frame comprises a girder frame and a secondary beam frame; auxiliary anchoring rod devices are arranged at the side parts of an auxiliary front beam and an auxiliary back beam; the front end of a main front vertical beam is hinged with a front beam assembly; a moving hydraulic cylinder is hinged between the main front beam and the auxiliary back beam; and the hydraulic stand column moves synchronously by means of assembling with a connecting rod together. The tunnel excavation staggered type supporting device provided by the invention has the advantages of reasonable structural design, stable supporting and moving, convenience in dismounting and maintenance, and high security and reliability. The tunnel excavation staggered type supporting device is entirely suitable for field and in-time support using conditions, can mechanically support an ejector plate which is just exposed to a tunnel excavation working face in time, can assist tunnel permanent supporting operations, such as an auxiliary screen, an anchoring rod and the like, and cover the continuous operation through a comprehensive mechanical excavator, so that the supporting quality and the excavation operation efficiency of the ejector plate of a tunnel can be obviously improved.

Description

technical field [0001] The invention relates to a support device for roadway excavation in mining, in particular to a staggered support device for roadway excavation that adopts mechanized means and a fully mechanized excavator for timely support on site, and is mainly used for roadway excavation Timely mechanized support for the newly exposed roof, auxiliary net laying and bolting, etc., and the cover mechanized excavator realizes continuous support operations in a certain area of ​​the roadway. It belongs to the field of mining machinery manufacturing and application. Background technique [0002] In the current mining, especially in the underground mining of coal mines, the tunneling operation of the roadway is a prerequisite for all other operations. With the widespread use of comprehensive mechanized roadheaders (referred to as "mechanized roadheaders"), the efficiency of roadway excavation has been greatly improved compared with the traditional "drilling and blasting"...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a roadway excavation staggered support device, which solves the problems in the prior art such as backward support means, difficulty in moving frames, need to stop operations, and low efficiency. It is stable, easy to load and unload and maintain, safe and reliable, fully conforms to the conditions of use for timely support on site, better meets the requirements of supporting operations for underground roadway support and fully mechanized excavators, and realizes timely mechanization of the newly exposed roof on the roadway excavation face Supporting, it can assist the roadway permanent support operations such as net laying and bolting, and protect the fully mechanized excavator to achieve continuous operation
