Problems solved by technology

Since the current filling method is to use manual methods to buckle the baffles one by one in the gob to form a long overall filling template, and then fill with the mixture, the labor intensity of the workers is high, the baffle

Abstract

The invention discloses a filling template bracket, which comprises a single hydraulic support post, a filling pipe, a base, a push hydraulic cylinder, a bottom support, hydraulic upright posts, an adjusting frame and a sealing rubber plate, wherein two hydraulic upright posts are arranged on two inner sides of a bottom support frame; the push hydraulic cylinder is horizontally arranged in the middle of the bottom support; the bottom of the push hydraulic cylinder is connected and fixed with the bottom support; a piston head of the push hydraulic cylinder is connected with the base; the single hydraulic support post is vertically arranged in the middle of the base; the bottom side of the single hydraulic support post is provided with the filling pipe; the sealing rubber plate and the adjusting frame are fixed at the upper end of each hydraulic upright post; a baffle plate is fixed on the bottom support on the outer side of the bottom of the hydraulic upright post; and the single hydraulic support post, the push hydraulic cylinder and the hydraulic upright posts are connected to a hydraulic operation valve. The automatic degree of the hydraulic control of the filling template bracket is high, a supporting requirement and the sealing requirement of the filling material can be met, working efficiency is improved and the labor intensity of workers is lowered.

Description

Technical field: [0001] The invention relates to a filling formwork support for filling the mined-out area under the mine. Background technique: [0002] Coal mining under villages, under buildings, and under water bodies is commonly referred to as "three under" coal mining in mining engineering, which is a technical problem in coal seam mining. The "three-down" coal mining technology mainly includes three forms: strip mining, room-and-pillar mining, and filling mining, while filling mining is called "green mining" and is the main development direction today. The current "three-down" coal mining Most of the technology adopts the filling mining method, which can extract all the coal, and fill the coal gangue and construction waste into the goaf, effectively preventing ground subsidence. Filling mining first uses coal mining equipment to extract coal, and then fills the goaf with mixture. After the gob is filled with mixture and forms support strength, coal mining equipment i...
