Embodiment Construction

[0016] The implementation of the present invention will be described in detail below with examples, so as to fully understand and implement the implementation process of how the present invention uses technical means to solve technical problems and achieve technical effects.

[0017] Such as figure 1 and figure 2 As shown, a kind of foldable advanced support of the present invention comprises a middle beam 1, and both ends of the middle beam 1 can be folded to be provided with side beams 5, and the lower sides of both side beams 5 are provided with at least one telescopic column 6 .

[0018] When a kind of foldable leading support of the present invention is supported under normal conditions, the two side beams 5 are in the open state, and the column 6 (the column is a telescopic column, and the expansion and contraction is completed by the hydraulic cylinder provided at the bottom) is in the extended state. state. With the advancement of the working surface, when it is ne...

Abstract

The invention discloses a folding forepoling. The folding forepoling comprises a middle beam, edge beams are arranged at the two ends of the middle beam in a foldable mode, and at least one telescopic stand column is arranged on the lower side of each edge beam. According to the folding forepoling, the problems that along with advancing of a working face in a roadway, when existing supporting equipment is used for moving in a manual operation mode, the working intensity is large, and the efficiency is low are solved.

Description

technical field [0001] The invention belongs to the technical field of coal mine support equipment, and in particular relates to a foldable advance support. Background technique [0002] Under the coal mine, support equipment is needed to support the top of the roadway, and the width of the support equipment is generally slightly smaller than the width of the mine road. [0003] The roadway advance support equipment or lag support equipment usually adopts the form of one-beam four-column support. As the working face advances, it needs to be moved forward. However, the current support equipment can only be used because it is fixed together as a whole. The manual handling method completes the movement and sends it to the designated location for continued support. This operation method is not only labor-intensive, but also inefficient. Contents of the invention [0004] The purpose of the present invention is to provide a foldable advance support, which solves the problems o...
