Abstract
The utility model relates to a coal mine underground pressure-resistant air door belonging to the field of coal mine underground roadway air doors. The coal mine underground pressure-resistant air door comprises an air door body, wherein the air door body is arranged in the middle of a wall body; and the air door is technically characterized in that the rigid wall body adopts a rigid structure, the air door body is arranged in the middle of the rigid wall body, and a circle of soft texture of sealing layers is arranged in the middle of the wall body. After improvement to the prior art, the structure of the rigid wall body is changed aiming at the characteristic of large pressure of the deeper roadway, the sealing buffer layer is additionally arranged, and the structure conforms to the environment characteristics of the coal mine roadway, therefore, the air door has the advantages of simple structure, easy implementation, easy maintenance and prevention of air leakage.
Description
Technical field
The utility model belongs to underworkings air door field, colliery, is specifically related to withstand voltage air door under a kind of coal mine.
Background technology
Air door is one of facility of coal mining enterprise's downhole production indispensability, mostly the body of wall of present air door is to adopt rigid structures, air door is installed in the middle of the rigidity body of wall then, the technician finds the extension along with the tunnel, the influence of the relation of being adopted, the mine internal pressure also increases gradually, distortion is serious behind the rigidity body of wall of prior art and the air door pressurized, cause extremely easily leaking out, and be difficult to maintenance, produce to enterprise and bring very big potential safety hazard, this problem of final result how, ensure the ordinary production of enterprise, eliminate the potential safety hazard in the manufacturing process, become the problem of technician's research.
The utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, provides a kind of simple in structure, easy to implement, for ease of maintenaince, and withstand voltage air door under the coal mine that is difficult for leaking out.
For achieving the above object, the utility model is achieved through the following technical solutions:
Be withstand voltage air door under a kind of coal mine, comprise the air door body, the air door body is arranged in the middle of the body of wall, and the present technique main points are that the rigidity body of wall is a rigid structures, and the air door body is arranged in the middle of the rigidity body of wall, and the soft sealant of a circle quality is set in the middle of body of wall.
The thickness of described sealant is 300～500 millimeters.
The utility model is after carrying out above-mentioned improvement to prior art, owing to be at the dark big characteristics of Tunnel Pressure, changed the structure of rigidity body of wall, increased the sealing cushion coat, and this structure meets the environmental quality in colliery tunnel more, therefore has simple in structure, easy to implement, for ease of maintenaince, be difficult for the advantage of leaking out.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1: mounting structure schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, withstand voltage air door under this coal mine comprises air door body 3, air door body 3 is arranged in the middle of the body of wall, the present technique main points are that body of wall is a rigid structures 2,4, and air door body 3 is arranged in the middle of the rigidity body of wall 2,4, and the soft sealant 1 of a circle quality is set in the middle of rigidity body of wall 2,4.
The thickness of described sealant 1 is 300～500 millimeters.
Like this,,,, also just ensured the sealing of air door body 3, air leakage phenomena can not occur in the rigidity body of wall 2 basic prototypes that keep because the protection of the soft sealant of quality 1 is arranged even if the distortion of a little appears in rigidity body of wall 4 pressurizeds.Even occurred little leaking out a little on the body of wall, also can handle by the mode of simply wiping one's face, so just solved the various deficiencies that exist in the prior art substantially.
The utility model is after carrying out above-mentioned improvement to prior art, owing to be for the dark big characteristics of Tunnel Pressure, changed the structure of rigidity body of wall, increased the sealing cushion, and this structure meets the environmental quality in colliery tunnel more, therefore has simple in structure, easy to implement, for ease of maintenaince, be difficult for the advantage of leaking out.
Claims (2)
