Description
Technical field
The utility model relates to Mechanical course fields, and in particular to a kind of air door mechanical locking device.
Background technique
Air door is one of essential facility in mine ventilation system, and the quality of air door locking largely determines
The quality of mine ventilation system, regulation in " safety regulations in coal mine " needed between main air entering and returning lane between air entering and returning well
The connection roadway used, it is necessary to install the positive air door and reverse throttle of twice locking.Air door closes not tight or cannot be latched,
It often results in twice air door to open simultaneously, so that Air escape branch, reduces the reliability and stability of ventilating system.If it happens exist
In main airway, not only can fan manufacture very big pressure, influence the service life of blower, can also be made due to abrupt pressure change
Side air door is closed suddenly, is easy to appear and is hurted sb.'s feelings or ruin an accident, and traditional throttle locking device uses weight-driven, often
The damage of appearance weight or wirerope break and air door are caused to be latched the problem of failing.
Utility model content
The utility model provides a kind of air door mechanical locking device, the shortcomings that overcome the prior art, the utility model
Eliminate the weight-driven that traditional throttle locking device uses so that entire throttle locking device is safer, prevent by
In weight damage and wirerope disconnected the problem of leading to air door locking failure.
In order to achieve the above objectives, the utility model adopts the following technical solution:
A kind of air door mechanical locking device, including the sleeve being separately mounted on two air doors, two sleeves are one end
The open structure of closing, the other end, and the closed end of two sleeves is oppositely arranged, is provided with tapered end in sleeve, the tapered end with
The keyhole cooperation being mounted on doorframe, and spring is provided between tapered end and the closed end of sleeve, the one end of tapered end towards spring
It is connected with traction rope, there are two pulley, the traction rope on two tapered ends is pierced by corresponding set for setting on the coal wall between two air doors
It is connected to respectively by two pulleys for adjusting the elastic silk column of traction rope behind the closed end of cylinder.
Further, shell is additionally provided on the coal wall between two air doors, the silk column is fixed in the housing.
Further, the traction rope is wirerope.
Compared with prior art, the utility model has technical effect beneficial below:
Firstly, the utility model eliminates the weight-driven that traditional throttle locking device uses, so that entire air door locking
Device is safer；Next strengthens the linkage effect of throttle locking device, by the cooperation of spring, tapered end and traction rope,
When one of air door is opened, another road air door is then voluntarily locked, and two pectinid doors is avoided to open simultaneously, and causes mine laneway distinguished and admirable short
Road solves weight damage that existing throttle locking device often occurs or wirerope is disconnected leads to asking for air door locking failure
Topic.
Detailed description of the invention
Fig. 1 is structure chart when air door mechanical locking device is in often receipts state；
Fig. 2 be air door mechanical locking device on one side be in normal receipts state, while be in structure chart when often putting state.
Wherein, 1, tapered end；2, spring；3, traction rope；4, sleeve；5, pulley；6, silk column；7, shell.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
Referring to Fig. 1 and Fig. 2, a kind of air door mechanical locking device, including the sleeve 4 being separately mounted on two air doors, two
A sleeve 4 is structure closed at one end, that the other end is open, and the closed end of two sleeves 4 is oppositely arranged, and is arranged in sleeve 4
There is tapered end 1, the tapered end 1 cooperates with the keyhole being mounted on doorframe, and is provided with bullet between tapered end 1 and the closed end of sleeve 4
Spring 2, tapered end 1 are connected with traction rope 3 towards one end of spring 2, pulley 5 there are two settings on the coal wall between two air doors, and two
Traction rope 3 on a tapered end 1 is pierced by behind the closed end of corresponding sleeve 4 to be connected to by two pulleys 5 for adjusting traction respectively
It restricts 3 elastic silk columns 6, shell 7 is additionally provided on the coal wall between two air doors, the silk column 6 is fixed in shell 7, described
Traction rope 3 is wirerope.
In use, traction rope 3 tenses when twice air door simultaneously closes off, spring 2 is in compressive state, lock in two tapered ends 1
First 1 is received in sleeve 4, and when opening wherein one of air door, traction rope 3 loosens, at the spring 2 in sleeve 4 on twice air door
In open configuration, tapered end 1 is stretched out from the open end of sleeve 4 to be cooperated with the keyhole on doorframe, and one of the air door that do not open is locked.
The utility model is described in further details With reference to embodiment:
The air door mechanical locking device of the utility model, which is used on underground air door, avoids two pectinid doors from opening simultaneously, and leads
A kind of device of mine laneway Air escape branch is caused, which is mounted on two door leafs of air door, controls by wirerope and spring 2
Tapered end 1 is used cooperatively with the keyhole being mounted on damper door frame achievees the effect that air door is latched；Usually two door leafs of air door are
It closes, air door mechanical locking device, which is in, at this time often receives state (Fig. 1), when wherein a pectinid door is opened, even with machinery
Locking device plays a role, and the tapered end 1 of two pectinid doors stretches out sleeve 4, and the tapered end 1 on the air door being not switched on enters the lock on doorframe
In eye, tapered end will not then enter in the keyhole on doorframe on the air door opened, thus realize the effect of another pectinid door locking,
Air door mechanical locking device becomes often to put state (Fig. 2) at this time.
The utility model eliminates the weight-driven that traditional throttle locking device uses, so that entire throttle locking device is more
Add safety；The linkage effect for strengthening throttle locking device simultaneously solves original air door by using interlock and is latched
There is weight damage and wirerope disconnected the problem of leading to air door locking failure in device.
In use, for spring 2 in compressive state, tapered end 1 is received in set in two sleeves 4 when twice air door simultaneously closes off
In cylinder 4, when opening one of air door, 4 inner spring 2 of sleeve is in open configuration, and tapered end 1 is stretched out of sleeve 4, is opened
The tapered end 1 of one of air door is stretched regardless of it, and another road the air door that do not open, and tapered end 1, which is stretched, has been inserted into keyhole on doorframe
It is interior, one of the air door that do not open is locked, allows suction side personnel to push away and does not open the door, to reach locking purpose, wirerope it is elastic
Silk column 6 by being mounted in the shell 7 among two air doors on coal wall is adjusted, and after twice air door simultaneously closes off, wirerope is drawn
Tightly, and 4 inner spring 2 of sleeve is drawn and arrives contraction state, tapered end 1 is recovered in sleeve 4 again.
