Abstract
The utility model provides an air door for mines. The air door comprises a door frame and a door board which are made of wooden boards and metal materials wrapped outside the wooden boards. The door board is wrapped by galvanized iron to form a seamless structure, so that air leakage is prevented well. Angle iron is wrapped on reinforcement beams of the door frame and the door board, so that strength of the door frame and the door board is improved well, and service life of the door frame and the door board is prolonged. In addition, a perspective window made of organic glass is arranged on the air door, so that people can observe situations without opening the air door, opening times of the air door are reduced, and service life of the air door is indirectly prolonged.
Description
Technical field
The utility model relates to ventilation equipment under a kind of coal mine, is specifically related to a kind of mine air door.
Background technology
In order to ensure the healthy of operating personnel, need aerating oxygen also to get rid of pernicious gas and coal dust under the coal mine before the coal mine operation, so the down-hole is equipped with ventilation system, guaranteeing has wind circulation continuously, and distinguished and admirablely also must reach certain requirement.But in order to prevent distinguished and admirable short circuit, also need isolation in the coal mine roadway, also will make things convenient for the current of people and state, so in coal mine roadway, be provided with air door.Air door is the ventilation equipment of coal mine operation, advancing, between the returnairshaft or advance, in the connection roadway between the return airway, both satisfied the needs of pedestrian and driving, playing again and cut off distinguished and admirablely, prevents the effect of distinguished and admirable short circuit.The coal mine lower wind door generally is no less than twice, and this twice air door can not be opened simultaneously, otherwise will cause distinguished and admirable short circuit, causes the accident of " an anti-threeway ".
The air door that uses at present is to be processed by wood materials mostly, and promptly the wooden boards with different in width is spliced, and scribbles pitch on its surface.Moist and have in the mine that etchant gas exists, air door is prone to be corroded and damages or distortion; After air door used a period of time, owing to the impact force of doorframe to door leaf, the crack appearred in door leaf wood board splicing place easily, causes and leaks out; It is short that air door has application life, shortcomings such as use cost height.Air door one damages or distortion and cause to leak out the ventilation quality is descended, thereby makes deficiency in draught in the tunnel, causes security incident easily.
The utility model content
The utility model will solve above-mentioned deficiency exactly, and a kind of mine air door is provided, and reaches to improve its intensity, expanded service life, and prevents the purpose of leaking out.
In order to reach above-mentioned effect, the utility model provides a kind of mine air door, comprises doorframe and door-plate, and said doorframe, door-plate are made up of wooden boards and the metal material that is wrapped in the wooden boards outside.
In order further to strengthen the intensity of door-plate, be provided with stiffening girder with the centre, said reinforcement deck-siding 400mm around the said door-plate.
Because door-plate is wrapped with metal material by timber and processes; Do not have the slit, check the situation on air door opposite for ease, be provided with the perspective window in the middle of the said door-plate; Said perspective window is processed by machine glass, and the size of perspective window is that 400mm * 300mm, height flush with ordinary people's sight line and be advisable.
In order to reduce use cost, said metal material is iron or galvanized iron, wrap up iron on the stiffening girder of general doorframe and door-plate, and the galvanized iron of door-plate parcel gets final product.
The beneficial effect of the utility model is: the galvanized iron of door-plate parcel constitutes jointless structure, has prevented well to leak out; Wrap up angle bar on the stiffening girder of doorframe and door-plate, improved its intensity well, prolong its application life; And on air door, be provided with the perspective window of processing by organic glass, and can not beat the situation that air door just can be observed the opposite, reduced the number of times of opening of air door, the useful life that has prolonged air door indirectly.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the utility model structural representation;
Among the figure: the 1-doorframe, the 2-door-plate, the 3-stiffening girder, 4-has an X-rayed window.
The specific embodiment
A kind of mine air door as shown in Figure 1 comprises doorframe 1 and door-plate 2, and said doorframe 1, door-plate 2 are made up of wooden boards and the iron that is wrapped in the wooden boards outside.Be provided with stiffening girder 3 with the centre, said stiffening girder 3 wide 400mm around the said door-plate 2.Be provided with perspective window 4 in the middle of the said door-plate 2, said perspective window 4 is processed by machine glass, and the size of perspective window 4 is that 400mm * 300mm, height flush with ordinary people's sight line and be advisable.
Stiffening girder in the utility model on doorframe and the door-plate all wraps up one deck angle bar, strengthens its intensity; And the galvanized iron of door-plate parcel one deck, the power when the minimizing door-plate is opened an account when strengthening intensity.Because door-plate is wrapped with iron by timber and processes, there is not the slit, both strengthened the intensity of door-plate, prevented well again to leak out; Wrap up angle bar on the stiffening girder of doorframe and door-plate, improve its intensity of worker well, prolong its application life; The convenience situation of checking the air door opposite; And on air door, be provided with the perspective window of processing by organic glass; The size of perspective window is that 400mm * 300mm, height flush with ordinary people's sight line and be advisable; Just can observe the situation on opposite not playing air door, reduce the number of times of opening of air door, the useful life that has prolonged air door indirectly.
Above embodiment is not limited only to the protection domain of the utility model, and all are based on the basic thought of the utility model and the protection domain that all belongs to the utility model of making amendment or changing.
