Description
Technical Field
The utility model relates to a steeply-inclined working face coal conveying channel telescopic waste rock blocking device.
Background
The steeply inclined coal seam which is already discovered in China has a wide distribution area, about 20 percent of the reserves which are already discovered belong to the steeply inclined coal seam, and the southwest area is concentrated to about 80 percent. Coal is a non-renewable resource, and only a steeply inclined comprehensive mechanized coal mining method is adopted in order to efficiently mine and solve mining conditions of low mechanization degree, low working efficiency, high labor intensity, low safety coefficient and the like. In a steep dip fully mechanized mining face, when a coal mining machine and a scraper machine need to be overhauled, an overhaul person needs to enter a coal conveying channel, and the dip angle is large and exceeds the self-sliding angle of coal gangue, the coal gangue of a rib can stride down at any time and fly and flee downwards along the coal conveying channel, and the overhaul personnel of equipment is seriously threatened. Therefore, during maintenance, the flying gangue in the coal conveying channel can be blocked only by using a single body, a net and a steel wire rope, and the mode is high in labor intensity; secondly, due to the large inclination angle, the operator is very difficult to stand, and needs to hold the steel wire rope with one hand and operate with the other hand, which is extremely unsafe; thirdly, the efficiency is low, and the normal production time is seriously influenced.
Disclosure of Invention
The utility model aims at: overcome prior art not enough, provide a scalable fender cash device of steeply-inclined working face fortune coal passageway, utilize hydraulic control, realize the fender cash effect of fortune coal passageway, raise the efficiency when guaranteeing maintainer safety.
The utility model discloses technical scheme realizes like this: a retractable waste rock blocking device for a coal conveying channel of a steep inclined working surface mainly comprises a primary waste rock blocking device, a supporting jack, a secondary waste rock blocking device, a retractable jack, a waste rock blocking device connecting seat, a supporting jack fixing pin, a retractable jack fixing pin and a waste rock blocking device hinge pin. The connecting seat of the waste rock blocking device and the fixing seat of the supporting jack are respectively welded on the left side and the right side of the top beam under the coal conveying channel just opposite to the top beam of the support. The primary waste rock blocking device is hinged with a connecting seat of the waste rock blocking device welded on the top beam of the bracket. The bottom end of the supporting jack cylinder is hinged with a supporting jack fixing seat welded on the top beam of the support, and the end of the piston rod of the supporting jack is hinged with a supporting jack fixing lug plate welded on the primary waste rock blocking device. The bottom end of the telescopic jack cylinder is hinged with a telescopic jack fixing lug plate welded on the primary waste rock blocking device, and the piston rod end of the telescopic jack is hinged with a telescopic jack fixing lug seat welded on the secondary waste rock blocking device. The support jacks are used for stretching and retracting to drive the primary waste rock blocking device to open and fold, and the telescopic jacks are used for stretching and retracting to drive the secondary waste rock blocking device to freely stretch and retract so as to adapt to the waste rock blocking requirements of different heights of the support. The utility model provides a pair of scalable fender cash device of steeply-inclined working face fortune coal passageway is installed on working face hydraulic support as required segmentation, should keep off the cash device for withdrawing fold condition when the coal-winning machine cuts coal, when needs are overhauld, opens this fender cash device, provides safe space for the maintainer.
