Description
Technical field
The utility model relates to a kind of interlock, particularly a kind of Air Throttle in Mine Pit interlocking self-closing device.
Background technology
At present, good air ambient and safety in production are arranged in the mine for the colliery, there are large-scale ventilation equipment to blow by force to the down-hole at coal mine well port, the wind that send has been full of whole mine, in order to reduce artificial air-supply loss, in the tunnel under the coal mine, air door is installed, for fear of the air-supply loss, make Air escape branch and cause potential safety hazard, described every place air door to be two roads, the passing rules at two sects can only be one gate open row opening wherein, another sect is for being necessary for closed condition, behind the first air door, open another road air door when current, last sect one is decided to be to be closed.
Because air door is under the effect of blast, have certain pressure, during by air door, two sects do not have interlock function, cause easily two roads to be opened simultaneously, make Air escape branch and cause potential safety hazard, have affected normal production.
The utility model content
The purpose of this utility model is that a kind of Air Throttle in Mine Pit interlocking self-closing device will be provided, and when solving by air door, two sects do not have interlock function, cause easily two roads to be opened simultaneously, makes Air escape branch and causes potential safety hazard, has affected normal production problem.
The purpose of this utility model is achieved in that this lock self-closing device comprises: release handle, closer, dead lock, air door, transition pulley, turnover pulley, emergent handle and wire rope;
Be connected with door closer at air door and doorframe rotating shaft end, open end at air door and doorframe and be connected with release handle and dead lock, air door with are connected the dead lock of air door and connect by wire rope, be connected with transition pulley and turnover pulley in the wire rope tracks, be connected with emergent handle at the rear portion of dead lock by wire rope.
Described release handle comprises: forward handle, oppositely shake hands, shake hands cross bar, pinch roller montant, pinch roller, cross bar axle sleeve and mounting base; Be connected with the cross bar axle sleeve at mounting base, the handle cross bar between two joint cross bar axle sleeves is connected with the forward handle; End at the handle cross bar is connected with reverse handle; The other end at the handle cross bar is bent with the pinch roller montant, is connected with pinch roller in the end of pinch roller montant.
Described reverse handle and forward handle have greater than 30 °, less than 90 ° angles; Described reverse handle and the end that is connected of handle cross bar have greater than 90 °, less than 180 ° angles.
Described closer comprises: front support, front support axle, connecting rod, the axis of the piston, piston, Compress Spring, piston bush, installing plate and bonnet; The front end of connecting rod is hinged by front support axle and front support, the rear end of connecting rod is by the axis of the piston and piston hinge, and piston is positioned at piston bush, is connected with bonnet in the bottom of piston bush, in the piston bush between bonnet and piston Compress Spring is arranged, be externally connected with installing plate at piston bush.
Described dead lock comprises: jack base, latch tongue, locating slot, set screw, latch storehouse, bolt axle, back-moving spring, rear stifled, axle pulling eye and mount pad; Stifled after the rear end in latch storehouse is connected with, rear stifled center is porose; Rear end at the latch tongue is connected with bolt axle, is socketed with back-moving spring at bolt axle, and bolt axle is positioned at the latch storehouse, and the rear end passes from rear stifled hole, at the afterbody of bolt axle the axle pulling eye is arranged; At the latch tongue locating slot is arranged, the front end in the latch storehouse has set screw, and set screw is positioned at the position of locating slot; Jack base is positioned at an end of latch tongue.
Beneficial effect: owing to adopted such scheme, this air door interlocking self-closing device, be that the identical device of two covers is installed in respectively on the twice air door, the twice air door all can utilize the release handle, open arbitrary road air door, after arbitrary road air door is opened, can under the effect of closer, air door be closed, be separately installed with dead lock at two sects, two dead locks are connected by wire rope, and after the installation, the latch tongue of each dead lock all is in open mode, when any one air door opened, under the effect of wire rope and dead lock, the air door that the latch tongue of another dead lock is not opened another road is locked, after the air door of opening is closed, the latch tongue that automatically restores to two dead locks all is in open mode, has realized the function that self interlocking is self-closing; When the twice air door all by locked and can't open air door the time, the emergent handle of pulling just can be opened air door.
Described release handle increases the arm of force according to the mechanics principle of lever and reduces pulling force, acts on the pinch roller by rotating shaft, and forward handle and is oppositely shaken hands, pinch roller of two common uses of handle, during the pulling handle, pinch roller rolls at doorframe, greatly reduces the frictional force of pinch roller and doorframe; Because the effect of lever can be used very little strength, just air door can be opened, overcome the monolateral unlatching of air door and the pressure difficult situation of opening the door greatly,
Described closer, when air door is opened, the connecting rod pushing piston, air line distance between the bonnet of piston bottom end and piston bush bottom is shortened, and piston is shifted, Compress Spring distortion generation elastic potential energy, the size that air door is opened is directly proportional with elastic force, it is larger to be that air door is opened, and elastic force is then larger, and elastic potential energy is larger, otherwise then less, when decontroling air door, the Compress Spring distortion is restored, and elastic potential energy discharges pushing piston and connecting rod is closed air door, displacement and the elastic force of closing are inversely proportional to, the displacement of namely closing is larger, and then elastic force is less, is conducive to reduce the collision of air door.
Described dead lock is made of back-moving spring, latch tongue, latch storehouse and jack base, respectively fill a cover at the twice air door, the logical wire rope interlocking of two cover dead locks connects, when the latch tongue is subject to external force, automatically being retracted into latch storehouse Zhong Men is opened, under the effect of back-moving spring, another road air door is then by locked.
Solved when the air door, two sects do not have interlock function, cause easily twice to be opened simultaneously, make Air escape branch and cause potential safety hazard, have affected normal production problem, have reached the purpose of this utility model.
Advantage: this self-closing interlock is simple in structure, can automatically be implemented between the twice air door to interlock, and when one air door opened, another road wind was inevitable locked, easy to use.Utilize the contractility of spring to automatically reset, solved because the pedestrian leaves air door and opened wide, and the major safety risks that cause Air escape branch to consist of make ventilation system stable, reliable.This release pull handle arrangement is simple, easy for installation, can use very little strength, just air door can be opened.
