Filling supporting partition board bracket

Abstract

The invention provides a filling supporting partition board bracket which comprises a protective side, a top beam, an upright, a four-rod mechanism and a base, wherein a front connecting bar and a back connecting bar are hinged on the base, and the upper end of the upper connecting bar is hinged on the top beam; the hydraulic bracket is also provided with a back top beam and a back base; the front end of the back top beam, the back end of the top beam and the upper end of the upper connecting bar are hinged with each other by pin shafts; two sides of the back top beam are hinged with upper side baffles; and two sides of the back base are hinged with lower side baffles. The filling supporting partition board bracket is provided with the upper and the lower side baffles; a gob is enclosed by the upper and the lower side baffles into a small area together with upper and lower baffles of a baffle bracket; and high water or concrete is filled from a slurry filling hole to implement filling operation; therefore, the filling supporting partition board bracket has the advantages of convenience for filling operation, high efficiency and realization of supporting integrated with extracting and filling; the front end of the back top beam, the back end of the top beam and the upper end of the upper connecting bar are hinged with each other by the pin shafts to form a structure with three coincided hinging points; and the upper connecting bar cannot be moved during the top beam or the back top beam is lifted in a swinging way so that the stability of the supporting bracket is assured and the problem of caving or gangue leakage of the top plate is avoided.

Description

technical field [0001] The invention relates to support equipment for comprehensive mechanized coal mining working faces in coal mines, in particular to hydraulic supports, in particular to a support for filling and supporting partitions. Background technique [0002] With the shortage of energy, the pace of coal mining in my country is accelerating day by day, and more and more mines are facing the problem of resource depletion. In order to solve the problem of "three downs" coal pressure. my country has adopted various technical measures such as traditional strip mining, relocation of villages, and filling mining to liberate the "three-down" coal pressing and increase the coal recovery rate. However, with the increase of mining depth, the increase of village relocation costs and the improvement of filling technology, filling mining technology has become a trend of vigorous development. At present, water-sand filling and wind filling are generally used for backfilling gobs...
