Description
Technical field
The utility model relates to a kind of underground work protector, specifically a kind of elevating conveyor tail hydraulic lock safety device.
Background technology
Fully-mechanized mining working reprints tail place charging aperture, because mobility is strong herein, if when scraper plate head groove overlaps not spacing with reprinting tail, the coarse coal produced when coal-winning machine walks to herein, wall caving will be deposited in herein, make personnel current inconvenient, cleaning is wasted time and energy, and sometimes also needs hand-holing to blow out etc. could clear up.If when scraper plate head groove and reprinting tail overlap and leave certain distance, although there is a change for the better in coal amount alluvial herein, but pedestrian has certain potential safety hazard to time herein, will cause the accident just in case slip, it is therefore a difficult problem for each ore deposit fully-mechanized mining working puzzlement herein always.
Summary of the invention
The purpose of this utility model is to solve above-mentioned problems of the prior art, and provides a kind of elevating conveyor tail hydraulic lock safety device.
The utility model is achieved by the following technical solution:
A kind of elevating conveyor tail hydraulic lock safety device, is characterized in that: comprise top protection, side protection and hydraulic system; Described top protection comprises cover plate, is hinged with first telescopic jack vertically arranged respectively, has the side plate vertically arranged in the bottom-hinged of another relative side at the two ends, bottom of a wherein side of cover plate; Described side protection comprises front apron and backboard, and forward and backward baffle plate is positioned at same plane and leaves distance therebetween; The lateral wall of front apron is provided with fence rail, and fence rail can front apron slide anteroposterior relatively, position front apron lateral wall being positioned at fence rail front end is also provided with horizontally disposed second telescopic jack, the piston rod end of the second telescopic jack and the forward end of fence rail hinged; The lateral wall of backboard is provided with roll guard, and roll guard can backboard slide anteroposterior relatively; Top protection in two the first telescopic jack be separately fixed at side protection on front apron and backboard on; Hydraulic system is for controlling stretching out or regaining of the first telescopic jack and the second telescopic jack.
During use, front apron is fixed in crusher side walls, and after scrapper conveyor moves forward, fence rail is in retracted state, and roll guard is in the state of stretching out; After elevating conveyor moves forward, fence rail is in the state of stretching out, and roll guard is in retracted state.Its advantage is: under normal circumstances; scrapper conveyor head is a little more than elevating conveyor base plate; but when being subject to the impact of geographical position condition; when scrapper conveyor head is more higher than elevating conveyor base plate degree; hydraulic system can be operated by two first telescopic jack jack-up; cover plate, also along with rise, well protects elevating conveyor tail hydraulic lock device.
Further, the part on the side of cover plate between two first hydraulic jack is evenly equipped with some root guard chains.After cover plate rises, the blank stayed after cover plate rises just filled up by some root guard chains, still can play closed effect.
The utility model device is successfully developed, and through on-the-spot investigation environment, thoroughly understand coal mining process, careful survey calculation, deliberate repeatedly, human oriented design, absorption advise in many ways, final design produces a whole set of elevating conveyor tail hydraulic lock safety device.This device fully achieves reprints tail charging aperture automatic telescopic function, in practice, have received good effect.
The utility model device assembles simple, easy to operate, safe and reliable, practical, to further enhance reprinting tail place security protection, not only can eliminate safe hidden trouble, but also far infrared rays can be replaced block people's device, become " hard protection " from original " soft protection ", greatly lower accident rate, has broad application prospects and promotional value very widely.
