Abstract
The utility model relates to a new interlocking composite air door concerned air door arranged in underground crossheading. The keys points of the utility model are as bellow: a composite air door is formed by embedding a smaller air door at the middle of a bigger air door, the rotary shaft available in the opening of the smaller air door is positioned on the doorframe of the bigger air door and shares the same bearing as the rotary shaft of the bigger air door, meanwhile, the two ends of an interlocking rope are fixed at one air-door opening near side of the door-plate of the smaller air door, thus, whether the smaller air door or the entire group of composite air doors in one group of composite air doors are opened, the other group of composite air doors (no matter is the bigger air door or the smaller air door) will be in an interlocking closed state. The utility model has a novel design and easy to use and really realizes the requirements presented in Safety Regulations of Coal Mine for the interlocking of two air doors of forward direction in the crossheading of mines.
Description
One, technical field
The utility model relates to the air door of installing in the connection roadway of a kind of down-hole.
Two, background technology
In the Safety of Coal Mine Production process of reality, for satisfying connection roadway pedestrian under the coal mine, vehicle passes through, the needs of main equipment transportation, particularly to satisfy the needs of picture by large-sized objects such as fully mechanized mining supporters, the specification of the air door of installing in the connection roadway of down-hole must be enough big, present mine large-scale mine about 4 squares particularly at the air door area of installing with connection roadway, about 300 kilograms of weight, the structure of the interlocking air door of prior art is that the strong wind door is fixed on the air door doorframe by its door-hinge, interlocking rope two ends are separately fixed on the door-plate of the big air door of twice forward near a side of opening air door, and by being fixed on guide securement point realization interlock on the wall.The interlock of big air door is to realize by the regular length of interlocking rope (when together big door opening, the maximum tension length of interlocking rope when the big air door in another road is closed).Since the air door thickness requirement, the just increase of the deadweight that causes air door undoubtedly, the difficulty of door opening., add that again the distinguished and admirable blast active force that imposes on the forward air door in some connection roadway place, down-hole is bigger, often cause personnel to open very difficulty or do not open at all.
Three, summary of the invention
Key issue to be solved in the utility model is a kind of novel interlocking combination air door of design, to overcome the problem that prior art exists, realizes making up air door and interlocks simultaneously, satisfies the needs of safety in production.
Implementation procedure of the present utility model is such:
In order to realize that making up air door interlocks simultaneously, satisfy the needs of safety in production, embedded little air door promptly constitutes the combination air door to the utility model in the centre of big air door, axis of rotation during little door opening be set on the doorframe of big air door and and the rotating shaft coaxle of big air door, simultaneously, the two ends of interlocking rope are fixed on the little air door door-plate near a side of opening air door, like this, no matter working as one group of combination air door little door opening wherein still is one group of combination door opening, and another group combination air door (no matter being big air door or little air door) then is in the interlocking closure state.
Good effect of the present utility model is: modern design, and easy to use, really realized the requirement of twice forward air door interlocking in " safety regulations in coal mine " mine connection roadway.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Five, the specific embodiment
As shown in drawings, the utility model is embedded little air door 5 in the centre of big air door 1, promptly constitutes the combination air door, and the area of little air door 5 accounts for 2/5 of big air door 1 area, can satisfy personnel and pass through needs; Axis of rotation when little air door 5 is opened be set on the doorframe of big air door 1 and and the axis of rotation 3 of big air door coaxial; Simultaneously, the interlocking rope air door fixed point 6 at the two ends of interlocking rope 2 is separately fixed on two little air door 5 door-plates near a side of opening air door, and by being fixed on guide securement point 4 realization interlocks on the wall.Like this, no matter working as one group of combination air door little door opening wherein still is one group of combination door opening, and another group combination air door (no matter being big air door or little air door) then is in the interlocking closure state.
When having only personnel to pass through, then only need to open little air door 5, need not open big air door 1, like this, the deadweight that personnel open air door has reduced, and simultaneously, acts on the malleation of opening on the air door and has also reduced, and the resistance that personnel open air door greatly reduces; As main equipment, when object need pass through, then open little air door 5 earlier, reduce to open the deadweight and the distinguished and admirable malleation that acts on the big air door of big air door, reduce the resistance of opening big air door, open big air door then, at this moment the resistance of opening big air door greatly reduces, and personnel have fundamentally solved by opening the difficulty of air door or the problem of not opening.
Claims (1)
1, a kind of novel interlocking combination air door is characterized in that: the embedded little air door (5) in the centre of big air door (1), promptly constitute the combination air door, and the axis of rotation (3) when little air door (5) is opened is coaxial with the axis of rotation (3) of air door (1) greatly; Simultaneously, the interlocking rope air door fixed point (6) at the two ends of the rope (2) of will interlocking is separately fixed at a close side of opening air door on two little air doors (5) door-plate, and by being fixed on guide securement point (4) realization interlock on the wall.
