Problems solved by technology

[0003] The object of the present invention is to provide a gangue filling support bracket. The gangue filling support bracket needs to solve the problem that the upper link of the filling bracket in the prior art is hinged to the rear part of the top beam, which causes the structure of the bracket to rise and fall. Unstable, prone to roof collapse or leakage of gangue, resulting in production safety accidents, and the technical problem that the scraper conveyor is fixed on the tail beam, which is inconvenient to adjust the gangue conveying path

Embodiment Construction

[0015] The present invention will be described in further detail below through embodiments in conjunction with the accompanying drawings.

[0016] Such as figure 1 , figure 2 and image 3 As shown, in the present embodiment, including the protection side 1, the top beam 3, the column 17, the four-bar mechanism, the base 19, the scraper conveyor and the compacting mechanism, a telescopic beam 25 is built in the front end of the top beam 3 along the front and rear direction, A telescopic beam jack 26 is hinged between the telescopic beam 25 and the top beam 3, and the guard 1 is hinged at the front end of the telescopic beam 25. By arranging the telescopic beam, the supporting range of the support can be enlarged. Side protection jack 2, front link 15 and rear link 14 are hinged on base 19, the upper end of upper link 16 is hinged on top beam 3, upper link 16, front link 15, rear link 14 and base 19 Mutually hinged to form a four-bar linkage mechanism, wherein the hydraulic ...

Abstract

The invention relates to a waste filling supporting bracket. The waste filling supporting bracket comprises a protective side, a top beam, an upright post, a four-rod mechanism, a base, a scraper conveyer and tamping mechanisms, wherein the hydraulic support is provided with a rear top beam; the front end of the rear top beam, the rear end of the top beam and the upper end of an upper connecting rod are hinged through a hinge pin; a rear upright post is arranged between the middle part of the rear top beam and the base; the rear part of the rear top beam is provided with a chute along the traverse direction; a rear slipping way is arranged in the chute; the rear end of the base is hinged with a waste baffle seat; and the tamping mechanisms are hinged on the waste baffle seat. In the wastefilling supporting bracket, the front end of the rear top beam, the rear end of the top beam and the upper end of the upper connecting rod are hinged through the hinge pin to form a structure of which three hinging points are superposed; the upper connecting rod cannot be moved when the top beam or the rear top beam is swung, lifted or put down, the stable structure of the supporting bracket is ensured, and the problem of top plate caving or waste rock leakage is solved. The waste baffle seat at the rear end of the base is provided with the two tamping mechanisms, fillers are more compactly filled, the overall strength of the fillers is improved, and the deformation of the earth surface is effectively controlled.

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 gangue filling support supports. 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. Water-sand fi...
