Abstract

The invention discloses a temporary supporting bracket with telescopic top beams and connecting rods and a supporting method. The temporary supporting bracket comprises a front bracket and a rear bracket, wherein the front bracket and the rear bracket have the same main structure and are respectively composed of longitudinal frames on the two sides and two cross beams, the front parts of the longitudinal frames are connected through one hydraulic stand column, and the rear parts of the longitudinal frames are connected through a four-connecting rod mechanism; the longitudinal frames form a stable planar structure; when tunneling roadways need to be supported temporarily, two temporary supporting brackets with the telescopic top beams and the connecting rods are adopted for supporting; the longitudinal frames are stable in structure, and the safety of tunneling construction is guaranteed; by operating two or more temporary supporting brackets in order, the safety of the tunneling work 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 ...
