Description
Technical field
The utility model relates to the coal mine lower wind door, is specially a kind of comprehensive safety and ensures damper system.
Background technology
In the tunnel under the coal mine, the effect of air door is to regulate air intake flow in the tunnel, dilution pernicious gas, and pernicious gas must not be transfinited, and guarantees downhole safety production.Air door is simultaneously again can guarantor's car current and do not make mine car damage air door.The twice air door can not be opened simultaneously, otherwise can cause distinguished and admirable short circuit, the accident that causes gas density to exceed standard even blast.Air door is the important device that coal mine downhole safety is produced, and generally there is mechanical type in the system that the control air door opens and closes, fluid pressure type, and vapour-pressure type, electrodynamic type etc., function ratio is more single.Although these air door control systems can play control action, still there are some security hidden troubles, the air door problem of leaking out for example lacks and opens and closes air door prompting warning function or the like.
Summary of the invention
Also there is the problem of potential safety hazard in damper system and provides a kind of comprehensive safety to ensure damper system the utility model in the prior art in order to solve.
The utility model is realized by following technical scheme, a kind of comprehensive safety ensures damper system, comprise twice air door at least, hydraulic locking device is installed mutually between the air door, wherein two of the per pass air door door body joints are that seam cooperates, and the fitting face place is provided with weather strip, is provided with weather strip between the doorframe of door body, and two door body tops of air door connect by quadric chain, be connected with backguy on a door body therein, backguy is provided with weight, is provided with pulley on doorframe, and pulley is walked around in backguy, be connected with backguy on the car lug before air door, backguy is connected with weight, is provided with the voice light alarming device above doorframe, and trigger switch is housed on door.
Compared with prior art, the utility model has at first used conventional hydraulic locking device, and when one air door opened, the lock cylinder of this device can firmly be inserted another road air door dead, had only after the air door of opening is closed again, and lock cylinder withdrawal air door just can be opened.Adopt seam to add the design of weather strip between the door body of air door and the doorframe, make appearance seem cleaner and tidier, and can thoroughly solve the problem of leaking out.Door body connected mode adopts four-bar linkage structure, realizes the stressed mutual balance that two air doors are fanned by wind-force conversion system internal force, becomes traditional unidirectional unlatching and is incorgruous unlatching, and it is easier to open.Air door is connected with weight, and after air door was opened, under the situation that the people does not initiatively close, air door was subjected to the pulling force of weight and can closes automatically, has avoided forgetting and has closed the door, the situation that Men Buhui closes automatically.And weight is connected with car arrester, and when air door was opened, car arrester was put down, and after door was closed, weight fell, and car arrester rises, and guarantees that the safety of door is not clashed into.Acoustic-optic alarm can also report to the state of operator's door at any time, in time closes the door to remind the operator.
In a word, the utility model has adopted four connecting rod thrust balancing devices, hydraulic locking device, and acoustic-optic alarm, the comprehensive insurance system of car arrester blocking device makes the air door more perfect functions, and easy to operate, safety factor is higher.
