Abstract
The utility model discloses a dust suppression hydraulic bracket for a fully mechanized coal mining face. The dust suppression hydraulic bracket comprises a bottom plate which is paved in a coal mining roadway, wherein a base is arranged on the bottom plate, the base is connected with a tail beam which is slantwise arranged via a first hydraulic connecting rod and a second hydraulic connecting rod, the other end of the tail beam is connected with a top beam which is horizontally arranged, a front beam is hinged to the front end of the top beam, a third hydraulic connecting rod is arranged on the bottom plate, and the upper end of the third hydraulic connecting rod is hinged to the lower surface of the top beam; a plurality of first nozzles are uniformly arranged on the lower surface and the two side surfaces of the top beam, a first storage tank which is used for storing dust suppression liquid is arranged in the base, a high-pressure pump is arranged in the first storage tank, and a plurality of first nozzles are connected with a pipeline of the high-pressure pump. Through the adoption of the dust suppression hydraulic bracket, the dust suppression efficiency is improved, and the adverse degree of the working environment of workers is reduced.
Description
Technical field
The utility model relates to a kind of depositing dust hydraulic support for fully-mechanized mining working.
Background technology
Along with the continuous innovation of driving face technology and improving constantly of comprehensive mechanization degree, when downhole production ability improves greatly, thereby the adverse circumstances such as the dust, noise, high temperature in operation place are constantly upgraded, the especially harm of work plane dust.Survey factually, in the situation that not adopting any dust prevention, the dust concentration that tunneling working face is met head on is 1200-1500mg/m
3, individually up to 3000mg/m
3left and right.Dust concentration is too high, easily causes gas and dust explosion accident, and the safe and efficient production of coal mining enterprise in serious threat, and causes huge economic loss.In addition, workers with long time, in high concentrate dust operation place, is easily suffered from professional pneumoconiosis.The number that pneumoconiosis is suffered from by coal enterprise accounts for the half that pneumoconiosis total number of persons is suffered from by China, brings very large misery to patient and family members.
Utility model content
In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of depositing dust hydraulic support for fully-mechanized mining working, to improve depositing dust efficiency, reduces the severe degree of the working environment of workers.
For solving the problems of the technologies described above, the utility model scheme comprises:
A kind of depositing dust hydraulic support for fully-mechanized mining working, it comprises the base plate for being laid on coal cutting roadway, wherein, on described base plate, be provided with base, described base is connected with the tail boom being in tilted layout by the first hydraulic connecting rod, the second hydraulic connecting rod, and the other end of tail boom is connected with the back timber of horizontal arrangement, and described back timber front end is hinged with front-axle beam, on described base plate, be provided with the 3rd hydraulic connecting rod, described the 3rd hydraulic connecting rod upper end is hinged on described back timber soffit, the soffit of described back timber, multiple the first nozzles on two sides, are evenly arranged, in described base, be provided with the first storage box for storing depositing dust liquid, in described the first storage box, be provided with a high-pressure pump, multiple the first nozzles are connected with described high-pressure pump pipeline, on described high-pressure pump, be provided with an electric-controlled switch, on the soffit of described back timber, be provided with one for controlling the dust inductor of described electric-controlled switch operation, described dust inductor is connected with described electric-controlled switch circuit, in described tail boom, be provided with the second storage box for storing depositing dust liquid, described the second storage box is connected with described the first storage box pipeline, on pipeline between described the second storage box and described the first storage box, be provided with electromagnetic valve.
Described depositing dust hydraulic support, wherein, described front-axle beam is triangle front-axle beam, has been evenly arranged multiple second nozzles on its inclined-plane, multiple second nozzles are all connected with described high-pressure pump pipeline.
A kind of depositing dust hydraulic support for fully-mechanized mining working that the utility model provides, on back timber, arrange multiple nozzles, and directly the first storage box, the second storage box are arranged in depositing dust hydraulic support, save cloth tube space, in the time that dust inductor detects in coal cutting roadway that dust concentration is too high, dust inductor control electric-controlled switch makes high-pressure pump work, depositing dust in the first storage box is also sprayed away and carries out depositing dust from nozzle, improve depositing dust efficiency, reduced the severe degree of the working environment of workers.
