Abstract
The utility model relates to an inletting and returning contact lane double air door switch in a mine ventilating system, in particular to a mechanical interlocking device for mine air doors. The mechanical interlocking device for the mine air doors fixes two groups of same transmission chains (1) inside an installing box (2) respectively; each transmission chain (1) comprises a guide post (3), a guide pipe (4), a return spring (5) and a pull rod (6); the pull rod (6) is connected with the guide pipe (4) through the return spring (5); and two toothed locking blocks (7) which are meshed with each other interact with the two groups of transmission chains (1). The mechanical interlocking device for the mine air doors can restructure the conventional manual air doors, can open and interlock a front air door and a back air door, and can prevent the ventilating short circuit caused by synchronous opening of the two air doors.
Description
Technical field
The utility model relates in a kind of mine ventilation system, returns the compound air door switch of connection roadway, is specifically related to a kind of Air Throttle in Mine Pit mechanical interlock.
Technical background
Along with the construction of modernized mine, the relief damper of the mutual locking of door opening drops into ventilation system under the coal mine more before and after can realizing, can be divided into type hand and automatic type in the operation.Self closing door is undoubtedly the development trend of current mine construction, but the conventional manual air door is still current many mines at the transient mode with air door because of not receiving the restriction of power sources such as liquid, gas, electricity.Design a kind of Air Throttle in Mine Pit mechanical interlock
,Transform the conventional manual air door, door opening interlocking before and after realizing prevents that the twice air door from opening simultaneously to cause ventilation short circuit (leakage) that the system that influences normally moves, and is very significant.
Summary of the invention
The purpose of the utility model provides a kind of Air Throttle in Mine Pit mechanical interlock, can transform the conventional manual air door, and door opening interlocking before and after realizing prevents that the twice air door from opening simultaneously to cause ventilation short circuit (leakage).
The technical scheme that the utility model adopts is: the inside that the driving-chain 1 of two groups of identical centers symmetrical distributions is separately fixed at install bin 2; Described driving-chain 1 is made up of lead 3, guide pipe 4, back-moving spring 5 and pull bar 6; Pull bar 6 links to each other with guide pipe 4 through back-moving spring 5, and two intermeshing profile of tooth lock dogs 7 and two groups of centrosymmetric each other driving-chains 1 interact.
The utility model compared with prior art has following beneficial effect: 1) interlock function: head
Blow in door in opening process, and another road air door can't be opened.Only first open air door close put in place after, another road air door can be opened.2) self-closing function: under the situation that does not have operation, the twice air door is normally off because the effect of spring force is enclosed within doorframe.3) unlocking function: when mechanical breakdown or chance accident, move air door either side handgrip, wire rope takes off handle to be loosened, and can open the twice air door simultaneously.
Description of drawings
Fig. 1 is the structural representation of the utility model,
Fig. 2 is the utility model scheme of installation.
The specific embodiment
As shown in Figure 1; The Air Throttle in Mine Pit mechanical interlock is the inside that the driving-chain 1 that two groups of identical centers are symmetrically distributed is separately fixed at install bin 2; Described driving-chain 1 is made up of lead 3, guide pipe 4, back-moving spring 5 and pull bar 6; Pull bar 6 links to each other with guide pipe 4 through back-moving spring 5, and two intermeshing profile of tooth lock dogs 7 and two groups of centrosymmetric each other driving-chains 1 interact.
The course of work: do not having under the external force effect, lead 3, pull bar 6 all are in reset mode under the effect of spring 5, and can open wherein any sect this moment; Open moment when first air door 8, driving-chain 1 is started working, and lead 3, pull bar 6 are under the pulling force of first air door 8; Overcome spring 5 translations, up to opening first air door 8 fully, in this process; Flute profile lock dog 7 is under the stirring of pull bar 6, and dead axle rotates 90 °, accomplishes the locking to second air door 9; When second air door 9 close put in place after, lead 3 resets under the effect of spring 5, flute profile lock dog 7 is in no operation state, first air door, 8 automatic unlockings.
The Air Throttle in Mine Pit mechanical interlock on the top board before and after being installed between the air door, utilizes the manual pulling force that first opens air door to pass through wire rope with another road air door locking, and the twice air door must not be opened simultaneously, protects distinguished and admirable not by short circuit.This product not only is suitable for the manual air door of single fan, is applicable to the configuration of biparting manual air door simultaneously.This product can be used in the production of manual air door, and is also configurable in the mounted traditional air door of mine is transformed.This product can be used as the safety product of mine ventilation system, under the operation of routine, greatly reduces the potential safety hazard of mine ventilation.
Claims (2)
1. Air Throttle in Mine Pit mechanical interlock; Two groups of identical driving-chains (1) are separately fixed at the inside of install bin (2); It is characterized in that; Driving-chain (1) is made up of lead (3), guide pipe (4), back-moving spring (5) and pull bar (6), and pull bar (6) links to each other with guide pipe (4) through back-moving spring (5), and two intermeshing profile of tooth lock dogs (7) interact with two groups of centrosymmetric each other driving-chains (1).
2. Air Throttle in Mine Pit mechanical interlock according to claim 1 is characterized in that, two groups of identical driving-chains (1) are symmetrical set for mutual center.
