Problems solved by technology

At present, domestic mines in this section generally adopt single pillar + π-shaped beam or forward-moving forward support for support. The former has low work efficiency and mechanization; Repeated support of the roof is not conducive to the safety management and maintenance of the roof, and it is easy to cause the roof to be broken. Both support methods have obvious disadvantages

Abstract

The invention provides a self-moving advanced bracket. The self-moving advanced bracket comprises a top beam, a base, a bottom plate, columns, side pushing jacks and supporting jacks, wherein the topbeam is a of a box-type structure, a horizontal connecting plate is connected to the two sides of the top beam in an upward mode; the top beam is connected to the upper ends of the two columns, the base is connected to the lower ends of the two columns, two cylindrical cavities are horizontally formed in the two ends of the interior of the base, and the two side pushing jacks are correspondingly installed in the cavities; the bottom plate is an L-shaped plate, the horizontal plate is arranged below the base, and the bottom plate is connected with the base through the side pushing jacks to forma side pushing mechanism; two of the four supporting jacks arranged on each side are correspondingly arranged on the both sides of the base, the upper ends of the supporting jacks are connected belowthe connecting plate of the base, and a fixing seat is connected to the lower ends of the supporting jacks. The self-moving advanced bracket has simple structure, easy manufacturing, and convenient operation and use; the side movement of the device is realized by using a self-moving mechanism, the device is pulled and moved to the front end of a advanced segment by using traction equipment such as a winch, the aim of no repeated supporting of the advanced bracket is realized, and the management level of a roadway roof is improved.

Description

Technical field [0001] The invention relates to a supporting equipment in a coal mine, in particular to a supporting equipment in the leading area of ​​the return airway of a fully mechanized mining face in a coal mine. Background technique [0002] According to the requirements of the "Coal Mine Safety Regulations": all safety exits and roadway connections in coal mining face must be strengthened within the range of influence of the advanced pressure, and the length of the reinforced roadway must not be less than 20m; comprehensive mechanized coal mining face, within this range The height of the roadway shall not be less than 1.8m. For other coal mining faces, the height of the roadway within this range shall not be less than 1.6m. At present, domestic mines generally use single pillar + π beam or step forward type of advanced support support in this section. The former has low work efficiency and mechanization; the latter is simple and convenient to operate, but this support me...
