Description
Technical field
The utility model relates to a kind of mining device, is specially a kind of door latch type pneumatic air door interlock.
Background technology
Known, according to " safety regulations in coal mine " the 109th, 118 relevant regulations: underground air door must be reliable, and mainly advance, between the returnairshaft and mainly advance, the air door of connection roadway must be interlocked between the return airway.
For ensureing that the down-hole ventilation system is stable, underground air door generally is provided with twice at least, guarantee under the situation that has pedestrian and vehicle to pass through, have at least one air door to be in closed condition, thereby prevent that the twice air door from opening simultaneously, distinguished and admirable short circuit taking place, cause the down-hole with the calm or gentle breeze in wind place, causes the ventilation safety accident.
But in actual underground work, owing to personnel walking with transportation is frequent and by reasons such as air door personnel ventilation safety poor consciousness, twice air door phenomenon may take place to open simultaneously, is practical, the effective way that prevents to open simultaneously the twice air door so air door is carried out interlocking.At present, what people generally used is chain, pneumatic interlock of mechanical type and electromagnetic chain device, the mechanical type interlock is chain to the air door implementation by pulley and lever, and this structural reliability is poor, locking is insensitive, fixed installation inconvenience such as the chain middle pulley that uses, wire rope; The electromagnetic chain device then needs to buy finished product, and price is higher, and the economic benefit of promoting the use of is not high; Pneumatic interlock is to realize the air door interlocking by the compressed air of down-hole as stretching of dynamic Control cylinder, though its good reliability, but because cylinder is unidirectional, there is not gas-returning devices, when opening air door, noise is big, and cylinder is fixed in the base plate, and it is big, difficult in maintenance that labour intensity is installed.So press for a kind of good reliability, convenient, the long-lived air door interlock of installation, maintenance.
Summary of the invention
There are defectives such as poor reliability, installation, maintenance inconvenience in the utility model in order to solve existing machinery formula interlock, pneumatic interlock and electromagnetic chain device, and a kind of door latch type pneumatic air door interlock is provided.
The utility model is to adopt following technical scheme to realize: door latch type pneumatic air door interlock, comprise the cylinder that is separately positioned on twice air door door leaf I, the II side, be provided with in the cylinder that an end and cylinder are fixed, the other end and stretch out the fixing spring of piston rod of cylinder, be provided with lock ring on the air door doorframe and with the corresponding position of piston rod; Also comprise the two-bit triplet stroke valve on the rear side doorframe that is separately positioned on air door door leaf I, II and doorframe hinged place, wherein the two-bit triplet stroke valve on one air door is connected the gas tube that also is provided with stack and is connected with compressed gas source on the two-bit triplet stroke valve by appendix with cylinder on another road air door.Two-bit triplet stroke valve described in the utility model is a kind of gas circuit conducting whether pneumatic element that is used to control for existing known products, and its internal construction and operating principle are that those of ordinary skill in the art knows, and described cylinder also is a known products.The utility model utilizes two-bit triplet stroke valve as the gas circuit control element, single-acting formula cylinder is as the executive component of blocking device, under the normal condition, the twice air door all is in closed condition, under the effect of two-bit triplet stroke valve, two cylinders are communicated with source of the gas, and piston rod overcomes spring force under gas pressure, be in contraction state; When opening wherein any one air door, be fixed on two-bit triplet stroke valve on this air door doorframe and move transposition along with opening of air door, blocking-up is attached thereto the logical cylinder gas transmission gas circuit that is fixed on another road door leaf, piston rod in the cylinder stretches out under the effect of spring force, insert in the supporting lock ring that is fixed on the corresponding doorframe, realize locking; After the air door that is opened is closed, the two-bit triplet stroke valve that is fixed on this air door resets, recovery is attached thereto the logical cylinder gas transmission gas circuit that is fixed on another road air door, and the piston rod in the cylinder overcomes spring force and is in compressive state, air door unlocking once more under the effect of air pressure.Like this, just realize coal-face twice air door is carried out the purpose of interlocking, guaranteed that the work plane unstable airflow is reliable, ensured production safety, and solid and reliable, be easy to safeguard, recycle the rate height.
Described appendix, stack and gas tube all adopt the PU pipe, and the PU pipe is existing known products.
Compared with prior art, the utility model adopts the cylinder be installed in respectively on the twice air door door leaf and the stroke valve arrangement on the doorframe, has the following advantages:
1, interlocking is sensitive reliable, can guarantee the reliable and stable of ventilation system, guarantees mine ventilation system safety;
2, small investment, quick and easy for installation;
3, noise is little, and appearance looks elegant can satisfy the requirement of safe mass standardization effort;
4, recruitment few, not fragile, be convenient to safeguard,
In a word, the utility model is simple in structure, reasonable in design, and result of use is good, and the air door applicable to each big mine laneway has certain popularization value.
