Abstract
The utility model provides an air door protection and interlocking tank car gear device which is safe, reliable and capable of avoiding ventilation accidents. The air door protection and interlocking tank car gear device comprises a track, an air door, two tank car gears, steel wire ropes and springs, wherein a tank car runs on the track, the air door controls air flow in an underground mine, the two tank car gears are used for controlling passage of the tank car and are located on the front portion and the rear portion of the air door respectively, the steel wire ropes are used for being connected with the air door, the front tank car gear and the rear tank car gear, and the springs are used for controlling the tank car gears to reset. The track penetrates through the center of the air door. The air door can be opened or closed in the mode that the steel wire ropes drive the front tank car gear and the rear tank car gear to be opened or closed. According to the air door protection and interlocking tank car gear device, when the tank car needs to pass through the air door, the air door must be opened manually before the tank car passes through the air door; as a result, expenses for air door maintenance, caused after the air door is damaged due to collision with the tank car are avoided, air flow disconnection, ventilation system disorder, transfinite gas and ventilation accidents caused after the air door is damaged due to collision are avoided, the safety factor of mine ventilation is improved, and considerable economic benefit and social benefit are obtained.
Description
Technical field
The utility model relates to a kind of throttle setting, and especially a kind of air door is protected chain tank latch device.
Background technology
When down-hole has mine car to pass through air door in the past, often there is manually not opening air door, directly clash into open air door with mine car, cause air door being damaged in varying degrees, increase air door maintenance cost, when serious, cause Air escape branch, ventilation system disorder, the generation of induced draught accident increases the dangerous coefficient of mine, gently gas exceeding limit, and heavy ore deposit is ruined people and is died.
Utility model content
The utility model provides a kind of air door safe and reliable, that avoid ventilation accident to occur to protect chain tank latch device.
Realize a kind of air door of the utility model object and protect chain tank latch device, comprise for air door distinguished and admirable under the track of tank car operation, control well, for what control that tank car passes through and be positioned at two tank shelves before and after air door, the spring for connecting the wire rope of air door and former and later two tank shelves and resetting for controlling tank shelves; Described track is through the center of air door; The opening and closing of described air door, can drive by wire rope the opening and closing of former and later two tank shelves.
On described track, by pressing guidance tape to be fixed with iron plate, on described iron plate, be fixed with pulley, for changing the transmission direction of wire rope.
Described track is provided with the sleeper for supporting track, and described sleeper is fixed in orbit by railway spike.
Described sleeper is provided with fixed pulley, for setting up wire rope.
Described tank shelves are screwed on track.
A kind of air door of the present utility model protects the beneficial effect of chain tank latch device as follows:
A kind of air door of the present utility model is protected chain tank latch device; the essential artificial air door of opening when tank car need to pass through air door; vehicle could pass through; avoid the air door maintenance cost causing after tank car impact damage air door, the Air escape branch causing after avoiding air door to break, ventilation system disorder; gas exceeding limit; the generation of ventilation accident, has improved mine ventilation safety factor, has considerable economic benefit and social benefit.
Accompanying drawing explanation
Fig. 1 is the structural representation that a kind of air door of the present utility model is protected chain tank latch device.
The specific embodiment
As shown in Figure 1, a kind of air door of the present utility model is protected chain tank latch device, comprises for air door 2 distinguished and admirable under the track 1 of tank car operation, control well, for controlling two tank shelves 11 that are positioned at air door 2 front and back that tank car passes through, the spring for connecting the wire rope 6 of air door 2 and former and later two tank shelves 11 and resetting for controlling tank shelves 11; Described track 1 is through the center of air door 2; The opening and closing of described air door 2, can drive by wire rope 6 opening and closing of former and later two tank shelves 11.
On described track 1, by pressing guidance tape 3 to be fixed with iron plate 4, on described iron plate 4, be fixed with pulley 8, for changing the transmission direction of wire rope 6.
Described track 1 is provided with the sleeper 5 for supporting track 1, and described sleeper 5 is fixed on track 1 by railway spike 14.Described sleeper 5 is provided with fixed pulley 7, for setting up wire rope 6.Described tank shelves 11 are fixed on track 1 by screw 13.
A kind of air door of the present utility model protects the operating principle of chain tank latch device as follows:
In the time will opening air door 2 (ventilation equipment), tank car could pass through.When air door 2 is closed, the state of tank shelves 11 in stoping tank car to pass through, now tank car cannot pass through; When air door 2 is opened, air door 2 pulls wire rope 6, and wire rope 6 arrives air door 2 former and later two tank shelves 11 by pulley 8 by force transmission, thereby air door 2 former and later two tank shelves 11 are opened simultaneously round about, now completes tank car process.In the time that air door 2 is closed, under the effect of the spring of tank shelves 11 bottoms in elastic potential energy, become kinetic energy, thereby make air door 2 front and back tank shelves 11 in closure state, (state that stops tank car to pass through) now tank car cannot pass through again.
Track 1 center between tank shelves 11 and air door 2 adds top sheave 8, tank shelves 11 bottoms are fixedly connected with wire rope 6, finally by a series of pulley, wire rope 6 is installed on air door 2, opens or closes to control opening and closure of air door 2 former and later two tank shelves 11 thereby form air door 2.
Embodiment recited above is described preferred embodiment of the present utility model; not scope of the present utility model is limited; design under spiritual prerequisite not departing from the utility model; various distortion and improvement that the common engineers and technicians in this area make technical solutions of the utility model, all should fall in the definite protection domain of claims of the present utility model.
