Hydraulic bracket for end of comprehensive mechanized filling coal face

Abstract

The invention relates to a hydraulic bracket for the end of a comprehensive mechanized filling coal face. The bracket comprises top beams, an upright post, a connecting rod mechanism, a head sliding oil cylinder and bases, wherein the connecting rod mechanism is reversely supported on the lower part of a front top beam; a scraper conveyor head installing and moving space is reserved and the head sliding oil cylinder is arranged on a middle base; a pushing device is arranged below a rear front beam jack and comprises a case fixed on a rear base; a sliding block and a sliding block pushing oil cylinder for pushing the sliding block to horizontally move are arranged in the case; the sliding block is hinged with a telescopic pushing oil cylinder; the lower part of the telescopic pushing oil cylinder is connected with a tamping adjustment jack of which the base is hinged to the lower part of the sliding block; the front part of the telescopic pushing oil cylinder is provided with a vibration generator; the head of the vibration generator is provided with a pushing plate direction adjusting oil cylinder and a pushing plate; the pushing plate is an arc plate with a small upper part and alarge lower part; and the arc surface of the pushing plate is provided with a nail-shaped compaction block. The bracket can realize the advance support and full cross section dense filling of the endof a fully mechanized mining face, and matched equipment movement simultaneously, and overcomes the defects at the end of the conventional filling working face.

Description

technical field [0001] The invention relates to a hydraulic support at the end of a working face, in particular to a hydraulic support suitable for simultaneous support and filling at the end of a mine comprehensive mechanized filling coal mining working face. Background technique [0002] In recent years, the fully mechanized mining and filling technology has developed rapidly, and the application of electro-hydraulic control hydraulic supports has greatly improved the level of coal mining technology. However, cross top beams and single pillars are still used for maintenance at the end of the comprehensive mechanized filling coal mining face. The requirements for strengthening the support method and the lengthening of the support distance make it difficult for the shearer to enter the tail of the transporter every time. It is necessary for the end maintenance workers to do the preparatory work in advance, that is, withdraw the single hydraulic prop and metal cross beam near...

AI Technical Summary

Problems solved by technology

Especially for some mines where the gangue at the end of the comprehensive mechanized filling coal mining face still uses traditional manual processing during the gangue filling process, the filling effect at the end is not ideal and the operation is slow, which affects the overall filling effect. Therefore, in solving the aforementioned problems Under the background, there is an urgent need for a machine that meets the effective support of the end and realizes the dense filling of the end gangue.
