The utility model provides an air door deformation back problem of leaking out, guarantee air door integrality, guarantee the effective amount of wind of working face.
Description
Technical Field
The utility model relates to a mining air door field, in particular to resistance to deformation non-pressure air door.
Background
Along with the extension of mine and the continuous deepening of exploitation degree of depth, the influence that the non-pressure air door in the pit in colliery received the roof pressure causes the air door to warp, receives the influence that the bottom plate is bloated to cause the air door to warp, causes the inside air leakage of mine, leads to the effective amount of wind of working face to reduce. At present, the coal mine underground air door cannot be used after being deformed, only the air door can be replaced again, and the effective air quantity of a working face cannot be timely and effectively guaranteed.
SUMMERY OF THE UTILITY MODEL
For the problem of the effective amount of wind of the unable working face of assurance after solving among the prior art air door deformation, the utility model provides a resistance to deformation non-pressure air door.
The technical scheme of the utility model is realized like this:
a deformation-resistant pressureless damper comprising: the bottom end of each air door is provided with one elastic mechanism, and the side part of each air door close to the top end of the air door is provided with one elastic mechanism; any set of elastic mechanism comprises an upper support plate, a lower support plate and one or more than one spring in a vertical compression state, all the springs are vertically fixed between the upper support plate and the lower support plate, and the upper support plate and the lower support plate are connected with the air door.
Preferably, the upper support plate and the lower support plate are both provided with angle irons.
Preferably, two springs are arranged between the upper support plate and the lower support plate.
Preferably, the resilient means at the bottom end of each damper is located offset from the axis of the damper.
Preferably, the resilient means on the side of each damper near its top end is located offset to the jaw of the damper.
Preferably, the top of the air door is provided with a flame-retardant rubber cushion.
The utility model has the advantages that: the utility model discloses a resistance to deformation non-pressure air door receives the roof plate and comes the pressure influence or the bottom plate is heaved back non-pressure air door along with removing at the non-pressure air door roof, and four sets of elastic mechanism bear the partial pressure influence, guarantee the air door integrality, guarantee the effective amount of wind of working face.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.
Fig. 1 is a schematic structural view of a deformation-resistant non-pressure air door of the present invention;
fig. 2 is a schematic structural view of the elastic mechanism shown in fig. 1.
In the figure:
1. an elastic mechanism; 2. a damper; 3. a flame-retardant rubber cushion; 11. an upper support plate; 12. a lower support plate; 13. a spring.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Example (b): a deformation-resistant pressureless damper comprising: at least four sets of elastic mechanisms 1, wherein the bottom end of each air door 2 is provided with one set of elastic mechanism, and the side part of each air door close to the top end thereof is provided with one set of elastic mechanism; any set of elastic mechanism 1 comprises an upper support plate 11, a lower support plate 12 and one or more than one spring 13 in a vertical compression state, wherein all the springs 13 are vertically fixed between the upper support plate and the lower support plate, and the upper support plate and the lower support plate are connected with the air door. The upper support plate and the lower support plate can be connected with the air door by adopting welding, bolt connection and other modes.
The upper supporting plate 11 and the lower supporting plate 12 are both set to be angle irons, so that the spring is easily connected, the air door is also easily connected, materials are easily obtained from the angle irons, and the structure is stable. Two springs are arranged between the upper support plate and the lower support plate, and balance is facilitated.
The elastic mechanism at the bottom end of each air door 2 is biased to the door shaft of the air door. And the elastic mechanism on the side part of each air door close to the top end of each air door is biased to the door jaw of the air door. The top of the air door is provided with a flame-retardant rubber cushion 3.
The sinking amount of the top plate of the non-pressure air door after being influenced by the coming pressure or the swelling amount of the bottom plate does not exceed 200mm, the top frame of the sinking air door of the top plate is also sunk along with the top frame under the influence of the pressure of the covered rock stratum, then an elastic mechanism on the air door deforms, the upper part of the air door is compressed, and the integrity of the upper part of the air door can be effectively ensured; when the bottom plate swells, the lower support plate elastic mechanism at the bottom of the door leaf of the air door also moves upwards along with the bottom plate, so that the integrity of the lower part of the door leaf is ensured.
After the non-pressure air door receives pressure influence, the door jaw department of two air doors is that the bottom of closing the department and air door of air door receives the influence, and the elastic mechanism who is close to the air door top bears partial pressure, and the elastic mechanism of air door bottom shares partial pressure, guarantees that the air door is complete, can effectually avoid reducing the effective amount of wind of working face.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
