Abstract
The utility model discloses and fly cash radical occlusion device in a kind of large tilt angle compound mining timbering machine road, it is the gear cash case that a hinged sagging bottom surface is uncovered below fully mechanized mining supporter two back timber front ends, a hinged telescopic oil cylinder below the longeron of top beam rear end, telescopic oil cylinder hydraulic circuit is connected with fully mechanized mining supporter control valve, and the post alive of telescopic oil cylinder is hinged with gear cash case again; Pass oil cylinder gear cash case internal fixtion two, the hydraulic circuit passing oil cylinder is connected with fully mechanized mining supporter control valve, and the push rod of passing oil cylinder installs waste rock board, makes waste rock board stretch out from gear cash case when the push rod of passing oil cylinder stretches out downwards.When work plane personnel need ingress engine road to construct, by operation fully mechanized mining supporter control valve, gear cash case is opened to hang by telescopic oil cylinder, and pass oil cylinder and released in gear cash case by waste rock board, formation is blocked; By in waste rock board income gear cash case after using, finally gear cash case is recovered on back timber, ensure that the safety in production of fully-mechanized mining working.
Description
Technical field
The utility model relates to underground coal mine fully mechanized mining supporter.
Background technology
At present, underground coal mine coal-face, is equipped with the hydraulic support of not unit-frame type.Due to work plane adopt dark large, inclination angle is large, pressure is large, complicated geological, roof cracking, very easily flies cash phenomenon, brings very big potential safety hazard to work plane safe working.Because personnel need frequent ingress engine road to carry out safeguarding the work such as top board, generally blocking by manually installing shelter, not only there is very large potential safety hazard, and labour intensity is large, efficiency is low.
Summary of the invention
For solving the existing deficiency manually installing shelter on fully mechanized mining supporter, the utility model designs and flies cash radical occlusion device in a kind of large tilt angle compound mining timbering machine road.
Technical scheme is, cash radical occlusion device is flown in a kind of large tilt angle compound mining timbering machine road, it is characterized in that, it is below by hanger and the sagging gear cash case of pin hinges one in fully mechanized mining supporter two back timber front ends, at the longeron of fully mechanized mining supporter top beam rear end below by hanger and pin hinges telescopic oil cylinder, telescopic oil cylinder hydraulic circuit is connected with fully mechanized mining supporter control valve, and the post alive of telescopic oil cylinder is hinged with gear cash case again, makes gear cash case pack up or sagging under the effect of telescopic oil cylinder; Above-mentioned gear cash case bottom surface is uncovered, oil cylinder is passed gear cash case internal fixtion two, the hydraulic circuit passing oil cylinder is connected with fully mechanized mining supporter control valve, and the push rod of passing oil cylinder installs waste rock board, makes waste rock board stretch out from gear cash case when the push rod of passing oil cylinder stretches out downwards; Gear cash case is sagging and waste rock board stretches out downwards time, shelter from fully mechanized mining supporter machine road, thus prevent flying cash and enter work plane.
Above-mentioned gear cash case is formed by the Plate Welding that 16mm is thick, and width is 1000mm, height 900mm, thickness 100mm.
The above-mentioned waste rock board of above-mentioned gear cash case adopts the steel plate that 20mm is thick to make, and width is 880mm, height 900mm.
When needing to widen gear cash width according to scene, can in the processing of above-mentioned gear cash case two side periphery screw, connect belt strip or the steel plate of one fixed width in gear cash case both sides with bolt.
When work plane personnel need ingress engine road to construct, by operation fully mechanized mining supporter control valve, gear cash case is opened to hang by telescopic oil cylinder, and pass oil cylinder and released in gear cash case by waste rock board, formation is blocked; By in waste rock board income gear cash case after using, finally gear cash case is recovered on back timber.
The utility model solves the anti-cash that flies in fully-mechanized mining working personnel machine road and to hurt sb.'s feelings problem, ensure that the safety in production of fully-mechanized mining working.Adopt mechanical type radical occlusion device simultaneously, not only solve personnel's ingress engine road and beat the potential safety hazard and labour intensity problem of blocking, and shorten greatly and block the time of installing, improve production efficiency, effectively reduce cost of production.

Fig. 2 is the lateral view of embodiment, there is shown telescopic oil cylinder.
In figure: 1-back timber, 2-first pin, 3-keeps off cash case, and 4-passes oil cylinder, 5-waste rock board, 6-telescopic oil cylinder, 7-second pin, 8-longeron
Detailed description of the invention
Cash radical occlusion device is flown in large tilt angle compound mining timbering machine road as shown in Figure 1-2, it is below by hanger and the hinged sagging gear cash case 3 of the first pin 2 in fully mechanized mining supporter two back timber 1 front ends, at the longeron 8 of fully mechanized mining supporter top beam rear end below by hanger and the hinged telescopic oil cylinder 6 of the second pin 7, telescopic oil cylinder 6 hydraulic circuit is connected with fully mechanized mining supporter control valve, the post alive of telescopic oil cylinder 6 is hinged with gear cash case 3 again, makes gear cash case 3 pack up or sagging under the effect of telescopic oil cylinder 6; Above-mentioned gear cash case 6 bottom surface is uncovered, oil cylinder 4 is passed gear cash case 6 internal fixtion two, the hydraulic circuit passing oil cylinder 4 is connected with fully mechanized mining supporter control valve, and the push rod of passing oil cylinder 4 installs waste rock board 5, makes waste rock board 5 stretch out from gear cash case when the push rod of passing oil cylinder 4 stretches out downwards; Gear cash case 3 is sagging and waste rock board 5 stretches out downwards time, shelter from fully mechanized mining supporter machine road, thus prevent flying cash and enter work plane.
Above-mentioned gear cash case 3 is formed by the Plate Welding that 16mm is thick, and width is 1000mm, height 900mm, thickness 100mm.
The steel plate that above-mentioned waste rock board 5 adopts 20mm thick makes, and width is 880mm, height 900mm.
When needing to widen gear cash width according to scene, can in the processing of above-mentioned gear cash case 3 liang of side peripheries screw, connect belt strip or the steel plate of one fixed width in gear cash case 3 both sides with bolt.
