Background technology
Driving face in coal mine often uses scraper-trough conveyer as main conveyance, and in order to improve ventilation system, part scraper-trough conveyer needs by air door body of wall.At projecting mine, need a kind of for preventing job site once there is the device that coal and gas prominent or gas explosion accident cause hazard scope to expand.At present, dead-wind-proof device installed by the scraper-trough conveyer of most protrusion-dispelling air door, but there is the shortcomings such as device complexity, fragile, manual operation sensitivity is low, the problem avoided greater disaster under can not effectively solving wind current control situation, need to research and develop novel protrusion-dispelling air door scraper-trough conveyer dead-wind-proof device, to meet mine safety production need of work.
Therefore, it is simple, easy to operate to produce a kind of structure, work and operational efficiency high, safety factor is high, and sensitive reliable protrusion-dispelling air door scraper-trough conveyer dead-wind-proof device, has market prospects widely.
Summary of the invention
For the deficiencies in the prior art, the utility model provide a kind of structure simple, easy to operate, work and operational efficiency is high, safety factor is high, sensitive reliable protrusion-dispelling air door scraper-trough conveyer dead-wind-proof device, to reach when mine generation gas explosion or coal and gas prominent accident, the toxic and harmful generation adverse currents such as gas can be stoped in time, effective control disaster area, guarantees mine safety production.
The technical solution of the utility model is achieved in that a kind of protrusion-dispelling air door scraper-trough conveyer dead-wind-proof device, comprise scraper-trough conveyer and scraper-trough conveyer cover, verge board is fixedly mounted on scraper-trough conveyer cover front end by the first tumbler, fixed mount one end is fixed on above scraper-trough conveyer cover, the fixed mount other end is connected with driver plate by the second tumbler, driver plate is connected with transmission rail, on the embedded connecting rod with being arranged on below fixed mount of transmission rail, anti-reverse plate one end is connected with scraper-trough conveyer cover by the 3rd tumbler, and the anti-reverse plate other end is hung on connecting rod by connection cord.
The length of described verge board is not less than the height in scraper-trough conveyer hole, and verge board is the platy structure that can rotate along with the first tumbler.
Described driver plate upper end is connected with one end of fixed mount by the second tumbler, and driver plate lower end is connected with transmission rail, and transmission rail can along with driver plate swing, and driver plate is the platy structure that can rotate along with the second tumbler.
Described anti-reverse plate one end is movably arranged on above scraper-trough conveyer cover by the 3rd tumbler, and the anti-reverse plate other end is connected with the bottom of connecting rod by connection cord, and the length of anti-reverse plate is not less than scraper-trough conveyer hole height.
The utility model has following good effect: first, this product structure is simple, easy to operate, verge board is fixedly mounted on scraper-trough conveyer cover front end by the first tumbler, fixed mount one end is fixed on above scraper-trough conveyer cover, the fixed mount other end is connected with driver plate by the second tumbler, driver plate is connected with transmission rail, on the embedded connecting rod with being arranged on below fixed mount of transmission rail, anti-reverse plate one end is connected with scraper-trough conveyer cover by the 3rd tumbler, and the anti-reverse plate other end hangs on connecting rod by connection cord; Utilize lever principle, overcome the defect of existing scraper-trough conveyer dead-wind-proof device; When mine generation coal and gas prominent or gas explosion accident, the toxic and harmful generation adverse currents such as gas can be stoped in time, effectively control disaster area, guarantee mine safety production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of protrusion-dispelling air door scraper-trough conveyer dead-wind-proof device, comprise scraper-trough conveyer 1 and scraper-trough conveyer cover 2, verge board 3 is fixedly mounted on scraper-trough conveyer cover 2 front end by the first tumbler 11, fixed mount 5 one end is fixed on above scraper-trough conveyer cover 2, fixed mount 5 other end is connected with driver plate 7 by the second tumbler 13, driver plate 7 is connected with transmission rail 8, on the embedded connecting rod 6 with being arranged on below fixed mount 5 of transmission rail 8, anti-reverse plate 10 one end is connected with scraper-trough conveyer cover 2 by the 3rd tumbler 12, and anti-reverse plate 10 other end is hung on connecting rod 6 by connection cord 9.
The length of described verge board 3 is not less than the height in scraper-trough conveyer hole, and verge board 3 is the platy structures that can rotate along with the first tumbler 11.Described driver plate 7 upper end is connected with one end of fixed mount 5 by the second tumbler 13, driver plate 7 lower end is connected with transmission rail 8, transmission rail 8 can along with driver plate 7 swing, and driver plate 7 is the platy structures that can rotate along with the second tumbler 13.Described anti-reverse plate 10 one end is movably arranged on above scraper-trough conveyer cover 2 by the 3rd tumbler 12, and anti-reverse plate 10 other end is connected by the bottom of connection cord 9 with connecting rod 6, and the length of anti-reverse plate 10 is not less than scraper-trough conveyer hole height.
Verge board 3 lower end rides on scraper-trough conveyer under gravity, and verge board 3 is partial to forward wind direction, along with coal stream height swing above scraper-trough conveyer, can keep off tight scraper-trough conveyer hole all the time, prevents that forward is distinguished and admirable to be leaked out by scraper-trough conveyer hole.Counter blow flow path direction is partial to by anti-reverse plate 10.
When mine generation coal and gas prominent or explosion time, powerful air-flow or shock wave promote driver plate 7 and rotate, driver plate 7 drives transmission rail 8 to promote connection cord 9, connection cord 9 departs from connecting rod 6, anti-reverse plate 10 falls to keeping off tight scraper-trough conveyer hole, and then stops that the toxic and harmfuls such as tunnel gas are spread to protrusion-dispelling air door 4 opposite side by scraper-trough conveyer hole.The toxic and harmful generation adverse currents such as gas can be stoped in time, effectively control disaster area, guarantee mine safety production.
