Embodiment Construction

[0040] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0041] Such as figure 1 , figure 2 , image 3 As shown, the support cover type staggered sliding temporary support bracket of the present invention includes two four-column frame bodies and hydraulic systems with the same structure; A three-dimensional frame composed of two longitudinal bottom beams 1 and four telescopic columns 2; wherein:

[0042] Two four-column frames are arranged front and back, respectively called the front frame and the rear frame. A push-pull cylinder 6 is arranged between the bottom beam 1 of the front frame and the rear frame, forming a front-pull and rear-push combined frame; Through the hydraulic system, the two four-column frames can be raised and lowered and can push and pull each other, so that the combined frame can move forward with the advancement of the working surface;

[0043] The beam 7 is also provi...

Abstract

The invention discloses a support-shield-type cross-slip temporary support bracket and a support method thereof. The temporary bracket comprises two four-column bracket bodies with the same structure and a hydraulic system; the four-column bracket bodies are arranged front and back, push-pull oil cylinders are arranged between bottom beams of the front bracket body and bottom beams of the back bracket body, and then a front-pull back-push combined bracket body is formed; cross beams are provided with at least two pairs of jacks, each pair of the jacks are provided with short cross beams, and each short cross beam can rise and fall alone to achieve supporting on partial top plates. When temporary support on an excavation roadway is performed, one group serves as an external group, the other group serves as an internal group, the width of the internal group is smaller than that of the external group, the internal group can enter the external group and penetrate through the external group, therefore, the external group and the internal group achieve transposition and independently move, and the purposes that the temporary support bracket moves flexibly in actual application and can be supported on most of the top plates when the exploded top plates are not flat or the top plates are not a complete plane are achieved.

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 201310022580.X discloses a self-moving temporary support hydraulic support for excavation working face and its support method, which includes a four-column front frame, a four-column rear frame and a hydraulic system; the front frame and the rear frame They are all composed of two longitudinal top beams, two longitudinal bottom beams and four telescopic columns. There are multiple cross beams on the two longitudinal top beams to form the top frame supporting the top plate. The four-column front frame and rear frame Nested together to fo...
