Abstract
The invention relates to a crush-resistant and anti-deformation underground roadway air door. The crush-resistant and anti-deformation underground roadway air door comprises a door leaf, a door frame, a door frame sleeve and a door leaf sleeve. The door frame sleeve is arranged on the outer side of the portion, making contact with a roadway, of the door frame. The door leaf sleeve is arranged at the lower end of the door leaf. The door frame sleeve and the door leaf sleeve are both a hollow cuboid rubber sleeve and can be pressed to deform easily, the air door is protected, and the air door is prevented from being pressed and deforming. The crush-resistant and anti-deformation underground roadway air door has the advantages that structural design is reasonable, installation is easy, the underground roadway air door can be prevented from deforming, normal opening of the air door is guaranteed, and maintaining and air door replacing frequency is reduced.
Description
Technical field:
The present invention relates to a kind of underworkings air door, particularly a kind of resistance to compression anti-deformation underworkings air door.
Background technology:
Because underworkings air door is arranged in the tunnel of very dark down-hole, pressure-bearing is comparatively large, although metal door anti-pressure ability is large, usually can generating portion or overall deformation, and affect the normal unlatching of air door.Maintenance or to change air door not only difficult, and impact is normal produces.
Summary of the invention:
The object of the invention is to solve the problem, a kind of resistance to compression anti-deformation underworkings air door that can prevent underworkings air door generation deformation is provided.
For achieving the above object, the technical solution used in the present invention is:
A kind of resistance to compression anti-deformation underworkings air door, comprise door leaf, doorframe, Door frame and door leaf cover, the outside contacted with tunnel at doorframe is provided with Door frame, is provided with door leaf cover in door leaf lower end.
Described Door frame is hollow cuboid rubber sleeve, is provided with bayonet socket in the side of Door frame, for blocking doorframe, forms a whole with doorframe.
Described door leaf cover is hollow cuboid rubber sleeve, being provided with bayonet socket, for blocking the lower end of door leaf, forming a whole with door leaf on the top of door leaf cover, and door leaf cover is inner is provided with several and dividing plates of consistency of thickness parallel with lower surface.
The invention has the beneficial effects as follows, reasonable in design, install easily, underworkings air door generation deformation can be prevented, ensure the normal unlatching of air door, reduce the number of times keeping in repair and change air door.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of Door frame.
Fig. 3 is the structural representation of door leaf cover.
In figure: 1 doorframe, 2 Door frames, 3 door leafs, 4 door leaf covers, 5 bayonet sockets, 6 lower surfaces, 7 dividing plates, 8 tunnels.
Detailed description of the invention:
As Figure 1-3, a kind of resistance to compression anti-deformation underworkings air door, comprise doorframe (1), Door frame (2), door leaf (3) and door leaf cover (4), the outside contacted with tunnel (8) at doorframe (1) is provided with Door frame (2), is provided with door leaf cover (4) in door leaf (3) lower end.Door frame (2) is hollow cuboid rubber sleeve, is provided with bayonet socket (5) in the side of Door frame (2), for blocking doorframe (1), forms a whole with doorframe (1).Door leaf cover (4) is hollow cuboid rubber sleeve, bayonet socket (5) is provided with on the top of door leaf cover (4), for blocking the lower end of door leaf (3), form a whole with door leaf (3), door leaf cover (4) inside is provided with several and dividing plates of consistency of thickness (7) parallel with lower surface (6).Door frame (2) contacts with tunnel (8) in the outside of doorframe (1); when tunnel (8) generation deformation extrudes anti-deformation underworkings air door; because Door frame (2) and door leaf cover (4) are hollow cuboid rubber sleeve; toughness is large; good springiness; easy compressive deformation, protection doorframe (1) and door leaf (3), prevent doorframe (1) and door leaf (3) to be extruded distortion.When door leaf cover (4) pressurized contacts tight with lane, door leaf (3) switch difficulty, keep the normal unlatching of door leaf (3) by excision door leaf cover (4) bottom part, reduce the number of times of maintenance and replacing air door.
