Description
Technical field
The utility model relates to channel of coal mining working surface dust trapping device used, is specially extension type and passes watering dust trapping device.
Background technology
Coal dust is one of large disaster of mine five, it pollutes underground air, reduce down-hole visibility, have an impact to miner is healthy, easily cause anthraco-silicosis, may blast under certain condition, also can cause the damage of down-hole mechanical, equipment, precision instrument, reduce service life of equipment, so the coal dust control of down-hole has just become vital task.Underground coal mine getting working face generally adopts Dust collecting net to carry out catching dirt, Dust collecting net generally has door case type Dust collecting net and curtain-type Dust collecting net, and door case type Dust collecting net easily damages when pedestrian or driving, does not have the effect of depositing dust, and need often maintenance, curtain-type Dust collecting net needs when pedestrian frequently to lift up, and causes catching dirt effect and greatly reduces, while starting wire side, gather superincumbent coal dust in a large number to drop, cause secondary pollution, pedestrian is also very inconvenient, and often damages.
Summary of the invention
The utility model catches dirt weak effect to solve existing Dust collecting net; Need the problem of often keeping in repair and mobile Dust collecting net workload is large, provide extension type and pass watering dust trapping device.
The utility model adopts following technical scheme to realize: extension type passes watering dust trapping device, the pulley track comprising left Dust collecting net, right Dust collecting net and be fixed on face roof, pulley track is provided with left chain wheel and right pulley, the lower end of the connecting rod of left chain wheel and the frame top of left Dust collecting net are rotationally connected, the lower end of the connecting rod of right pulley and the frame top of right Dust collecting net are rotationally connected, left side and the right side of the frame bottom of left Dust collecting net are respectively equipped with universal wheel, and left side and the right side of the bottom of the frame of right Dust collecting net are respectively equipped with universal wheel.
When having pedestrian or vehicle passes through, rotate left Dust collecting net and right Dust collecting net, left Dust collecting net and right Dust collecting net respectively with the connecting rod of left chain wheel and right pulley for axle rotates, after left Dust collecting net and right Dust collecting net all rotate 90 degree, push left Dust collecting net and right Dust collecting net to two ends respectively again, pedestrian or vehicle just by; If when minority individual or dilly pass through, left Dust collecting net or right Dust collecting net only can be rotated, minority individual or dilly can be made to pass through.
Above-mentioned extension type passes watering dust trapping device, and pulley track is provided with water curtain; During the shower nozzle water spray of water curtain, water smoke grain, under distinguished and admirable effect, can be trickled down on the wire side of left Dust collecting net and right Dust collecting net uniformly, water smoke grain from top to bottom flows at the online integrated globule, form online the effect that moisture film plays " down-hole mouth mask ", can better purify distinguished and admirable, effective depositing dust.
Above-mentioned extension type passes watering dust trapping device, the top of the frame of left Dust collecting net 1 and right Dust collecting net 2 and bottom are all provided with sleeve pipe, slide in sleeve pipe and be inserted with sliding tube, Dust collecting net is connected with, along with the passing of work plane, when replacing position is carried out to dust trapping device between two sliding tubes, due to the difference of drift section, the sliding bar of left Dust collecting net and right Dust collecting net upper and lower side frame can be regulated, make Dust collecting net cover whole section, thus play better dust-laying effect.
The beneficial effects of the utility model are:
1) by rotating and pass left Dust collecting net and right Dust collecting net facilitates people's car to pass through, reduce and damage, and pulley guide rails installs water curtain, when shower nozzle spray water, good formation one moisture film on wire side, reaches good dust-laying effect; Be applicable to coal mine underground tunneling roadway, stope return aircourse;
2) conveniently moving, reaches installation site by passing can be directly to, thus reduces workload;
3) old cheap, fitting operation is simple, practical, without the need to being equipped with special messenger's operation, and greatly reducing the replacing number of times of Dust collecting net, improve dust-proof effect.
4) cover tunneling boring, during each replacing position, tunneling boring can be reached according to the size adjustment expansion link of drift section and cover, improve dust-proof effect.
