A longitudinal self-moving forepoling

Abstract

The utility model discloses a kind of longitudinal formula self-moving advanced support, including telescopic column, roof beam, slide rail and push-pull cylinder, the quantity of telescopic column is multiple, each telescopic column is vertically arranged, multiple telescopic columns are sequentially arranged along the length direction of slide rail, the top of each telescopic column is equipped with roof beam, roof beam is equipped with slide, slide rail is through slide and is slidably connected with roof beam;The quantity of push-pull cylinder is multiple, push-pull cylinder is set one by one with roof beam, each push-pull cylinder is arranged along the length direction of slide rail, one end of push-pull cylinder is hinged with roof beam, the other end of push-pull cylinder is connected with slide rail.The technical effect reached is as follows: by the mode of grouping control, self-moving along the length direction of slide rail can be realized, the whole device structure is simple, small, can be applicable to various roadway, and the universality is strong, original roadway support is not damaged in moving process, and still can realize stable supporting effect in moving process, more safe and reliable, can effectively guarantee on-site operation safety.
