Abstract

The invention discloses a telescopic top beam connecting rod type temporary support bracket and a support method. The temporary support bracket adopted includes a front frame and a rear frame. The main structures of the front frame and the rear frame are the same, and both sides The longitudinal frame is composed of two cross beams. The front part of the longitudinal frame is connected by a hydraulic column, and the rear part is connected by a four-bar linkage; so that the longitudinal frame forms a stable plane structure; when the tunnel is temporarily supported, two sets of The above-mentioned telescopic top beam connecting rod type temporary support support is used for support; the longitudinal frame structure is stable, which is safe for tunneling construction; through sequential operation of more than two sets of temporary support supports, the safety of the tunneling working face can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technology of temporary support for roadway excavation working face. Background technique [0002] At present, the temporary support forms used in the underground excavation working face include "wearing hat point column" support, front probing beam support and temporary support bracket. The closest technique to the present invention is the use of temporary support brackets. Chinese patent 201420137745.8 discloses a top beam telescopic excavation work face temporary support bracket, which includes a four-column front frame and a four-column rear frame, and two moving jacks are arranged between the front frame and the rear frame; The main structure of the rear frame is composed of two longitudinal frames connected with two beams; the longitudinal frame includes a top frame, a base and side columns on both sides, and the side columns are telescopic hydraulic columns; It is pulled on the base of the front frame and the rear ...
