Description
Technical field
The utility model relates to the automatic blocking between twice air door and anti-collision device under a kind of coal mine.
Background technology
Under coal mine, when mine car soon arrives air door, staff opens air door in advance, after mine car passes through, then closes air door.Sometimes the air door that do not have enough time to open, mine car just arrives direct bumping air door, also have mine car through after, close not in time air door, easily cause security incident.When one air door opened, another road air door is likely also opened, and air quantity will flow in a large number along tunnel the place ahead, air quantity runs off, and causes other tunnel air feeds not enough, affects the air feed of other work planes, field personnel's life security can not get ensureing, greatly dangerous.
Summary of the invention
Dangerous in order to overcome manual control switch's air door, the defect being prone to accidents, the utility model provides a kind of mine air door automatic blocking and anti-collision device, and this mine air door automatic blocking and anti-collision device can make air door safety switch, stop the generation of accident.
The technical solution of the utility model is: this mine air door automatic blocking and anti-collision device comprise twice automatic ventilation door locking device and air door anti-collision device, twice automatic ventilation door locking device comprises A air door and B air door, one end of A wire rope and A air door are fixedly linked, and the other end of A wire rope changes direction through A fixed pulley and is fixedly linked with the sliding tube that is positioned at the A air door interlocking mechanism of the middle side near tunnel of twice air door; One end of B wire rope and B air door are fixedly linked, and the other end of B wire rope changes direction through B fixed pulley and is fixedly linked with the sliding tube that is positioned at the B air door interlocking mechanism of the middle side near tunnel of twice air door; Interlocking mechanism has two groups of slide mechanisms and a fan-shaped turnover panel, the sliding tube of slide mechanism is arranged in stationary pipes, two integrally welded slide mechanisms are vertically fixed on floor, fan-shaped turnover panel is arranged on centre position directly over two slide mechanisms, fan-shaped turnover panel is being fixed near circle centre position, and the fixed point of take can rotate as fulcrum.
The stressed A sliding tube that pulls of A wire rope when A door opening, A sliding tube takes up fan-shaped turnover panel to the upset of B sliding tube, and the sliding tube of restriction B slide mechanism cannot be pulled out, and B air door cannot be opened.After A air door is closed, A wire rope is no longer stressed, and A sliding tube sets back.During B door opening, coupled B wire rope pulls fan-shaped turnover panel upset, is restricting the unlatching of A air door.
Air door anti-collision device comprises choker rod, one end and the air door of choker rod are movably connected, the other end of choker rod and one end of connecting rod are movably connected, the other end of connecting rod and one end of steering spindle are movably connected, the other end of steering spindle and one end of drive rod are movably connected, the other end of drive rod and one end of middle fork are movably connected, the center of middle fork is provided with axis of rotation, one end of middle fork is movably connected through left lever and left car arrester, left car arrester is pressed on left track, the other end of middle fork is movably connected through right pull bar and right car arrester, right car arrester is pressed on right track.
Choker rod is the linkage of car arrester and air door, and the Push And Release of air door provides power to car arrester, and its power is to be delivered on car arrester by choker rod.While opening air door, choker rod is stressed to be tightened up, and by connecting rod and steering spindle, is delivered on drive rod and left and right pull bar, middle fork moves round about because being subject to the inside thrust in both sides, left and right car arrester is separated to track two outsides respectively, de-orbits, and mine car is current.When air door is closed, choker rod is stressed to be pushed back, and middle fork returns to original position under the effect of left and right pull bar, and car arrester backs on track, and stops mine car current.Normal condition lower wind door is in closed condition, and car arrester keeps blocked state.While opening air door, car arrester de-orbits, and mine car is current.
Advantage of the present utility model: between twice air door, automatic blocking guarantees ventilation safety, prevents the short circuit of ventilating, reduces air quantity and runs off, and can effectively ensure ventilation safety.Air door anti-collision device is to form locking between air door and track, and the open and close of air door and the interlock of the car arrester on track protect air door to prevent from clashing into effectively, reduce potential safety hazard.
Between twice air door, carry out automatic blocking, assurance twice air door can only be opened together, and after one air door opened, another road air door cannot be opened, and air quantity can not flow forward in a large number, reduces air quantity and runs off.For preventing mine car bumping air door, air door and car arrester mutual linking, during door opening, mine car is current; When air door is closed, car arrester stops mine car current, and protection air door, prevents mine car bumping air door.
Effectively control air quantity, prevent that air quantity runs off, safeguard work face air quantity is rationally supplied.In door opening, mine car is current, and when air door is closed, car arrester stops mine car operation, prevents mine car bumping air door.
(1) twice air door is realized automatic blocking, and reasonable distribution air quantity supply improves the utilization rate of air feed system, avoids the security incident brought because of air quantity skewness, also reduces unnecessary air feed waste simultaneously.Prevent that mine car bumping air door device from being to guarantee that air door is injury-free, the safety of protection ventilation equipment, extends air door application life, reduces the generation of underground ventilating accident, guarantees mine safety production.
(2) this device does not relate to power supply, energy-saving safe, and power resources rely on the suffered slide force of the Push And Release of air door completely, failure rate is low, a little repair, the hidden danger rate of reduction ventilation accident, for ensureing mine ventilation safety, the raising work plane effective time plays an important role.
(3) reasonable in design, easy enforcement simple for production, installation, maintenance is convenient, and handling safety is reliable, has practicality.
