Abstract
The invention relates to a locking device for air doors. The locking device for air doors belongs to a safety device of mine ventilation doors. The locking device for air doors comprises a wire rope connected with the air doors, and the wire rope is arranged in an underground tunnel and behind a fixed pulley. A hanging pole is arranged at the end of the wire rope. The locking device for air doors is characterized in that two air doors connected with the hanging pole are arranged side-by-side in a limiting device and restrict the up-down movement of the hanging pole. A control valve is arranged at the upper part of the two hanging poles. A valve core of the control valve is pushed to the upper part of the other hanging pole and locks the hanging pole by the hanging pole which is pulled up. The locking device of air doors has the advantages of replacing a simple brake locking with a hanging bucket, utilizing the locking with hanging ropes and a broke valve.
Description
Technical field
The present invention relates to a kind of air door locking interlock, belong to a kind of safety means of mine ventilation air door.
Background technology
That applies at this stage is made up of chain rope, pulley, well-bucket to pull-type air door, and feature is that composition structure is simple, personnel
By when side pull open air door, opposite side realizes locking, but chain has certain preset space, and air door is in both sides simultaneously
During push-and-pull, a certain distance can be opened in both sides, and at this moment personnel are forced through and are possible to occur to squeeze hinder accident, there is safety
Hidden danger.
Content of the invention
The present invention relates to a kind of throttle locking device, solve existing air door potential safety hazard present in opening process.
For achieving the above object, the technical solution used in the present invention is：A kind of throttle locking device, including connection air door
Steel wire rope, steel wire rope sets the suspension rod of suspension around being located in end after setting pulley in tunnel, it is characterized in that, the connected steel wire of two air doors
Suspension rod on rope is disposed side by side in stopping means and limits suspension rod and moves in above-below direction, and described two suspension rods set one on top
Control valve, the valve element of control valve is pushed into another suspension rod top by this pull-up suspension rod after side suspension rod is pulled up and locks this suspension rod
Live.
As preferably levying be, described stopping means be fixing set the retainer ring that suspension rod runs through middle part spacing hole, each hangs
At least two groups of the retainer ring of bar, described retainer ring is fixed on frame plate, and frame plate is fixed in wall.
Further preferred, described control valve include can horizontal direction side by side is slided along suspension rod on suspension rod valve element,
Valve element two sides are provided with least two groups springs, and one end fixed spool side other end of one group of spring is fixed on the other frame plate of suspension rod
On, another group of spring is arranged symmetrically in valve element both sides with above-mentioned spring.
Further preferred, the side of described valve element is provided with chute, sets slip limit body in chute, and slip limit body is solid
Due to frame plate.
Preferably, described valve element sets round and smooth arcwall face, the side of valve element and arc with the contact site drift angle of suspension rod
The smooth excessive valve element inclined-plane in face, the medial surface top of described suspension rod sets suspension rod inclined-plane, between suspension rod inclined-plane and suspension rod top-side
It is connected by fillet.
It is an advantage of the current invention that：This device instead of on chain and simply brakes locking by well-bucket, but uses instead
Suspension rod and brake valve carry out locking.When side, air door is opened, and brake valve can be pushed on opposite side air door suspension rod by suspension rod, thus having
Suspension rod on the right side of effect locking, ensure that both sides air door can not be opened simultaneously, it is to avoid unsafe factor.Apply this transformation
Afterwards, air door locking potential safety hazard substantially reduces, do not occur personnel squeeze hinder accident, the personal safety to staff serves pole
Big protective effect, has reached Expected Results.
Brief description
Fig. 1 is the overall structure diagram of the present invention,
Fig. 2 is the structural representation of the control valve of the present invention.
Reference：
1 steel wire rope, 2 fixed pulley, 3 suspension rod, 4 control valve, 5 retainer ring, 6 spacing hole, 7 frame plate, 8 valve element, 9 spring, 10 chute 11 slip limit body
12 arcwall face, 13 valve element inclined-plane 14 suspension rod inclined-plane.
Specific embodiment
Throttle locking device as shown in Figure 1, including the steel wire rope 1 connecting air door, steel wire rope 1 is after fixed pulley 2 at end
End sets the suspension rod 3 of suspension, it is characterized in that, the suspension rod 3 on the connected steel wire rope of two air doors 1 is disposed side by side in stopping means and limits
Suspension rod 3 moves in above-below direction, and described two suspension rods 3 set a control valve 4 on top, and the valve element 8 of control valve 4 is in side suspension rod 3
After being pulled up by this pull-up suspension rod be pushed into another suspension rod top and by this suspension rod pin.
Stopping means is the fixing retainer ring 5 that suspension rod 3 runs through middle part spacing hole 6 that sets, the retainer ring 5 of each suspension rod 3 to
It is two groups less, described retainer ring 5 is fixed on frame plate 7, and frame plate 7 is fixed in wall.Control valve 4 includes can be on suspension rod 3
The valve element 8 sliding along suspension rod horizontal direction side by side, valve element 8 two sides are provided with least two groups springs 9, one end of one group of spring 9
The fixed spool 8 side other end is fixed on the other frame plate of suspension rod 3, and another group of spring 9 is symmetrical in valve element both sides with above-mentioned spring
Arrangement.
The side of valve element 8 is provided with chute 10, sets slip limit body 11 in chute 10, and slip limit body 11 is fixed on frame plate 7.
Valve element 8 sets round and smooth arcwall face 12, the side of valve element 8 and the smooth excessive valve of arcwall face 12 with the contact site drift angle of suspension rod 3
Core inclined-plane 13, the medial surface top of described suspension rod 3 sets suspension rod inclined-plane 14, passes through circle between suspension rod inclined-plane 14 and suspension rod 3 top-side
Angle is connected.
Working method
This device be instead of with suspension rod and brake valve on chain and simply brakes locking by well-bucket, and when side, air door is opened, wind
Door drives steel wire rope pull-up, and steel wire rope drives suspension rod to move upwards, and because suspension rod is located at the spacing in the hole of retainer ring, suspension rod can only
In above-below direction motion.During suspension rod pull-up, suspension rod inclined-plane is contacted with the arcwall face of valve element and by inward-facing for arc side
Square applying power, the effect due to slip limit body of valve element, valve element can pull up another Slideslip of suspension rod, and suspension rod inclined-plane continues
Arcwall face applying power to valve element, suspension rod chamfered transition to valve element contact of incline plane, until valve element is pushed on opposite side suspension rod
Side.Upper side due to opposite side suspension rod is hindered by valve element, and now another pectinid door can thoroughly be closed, even if to another fan
Air door exerts a force, and due to not having any space between valve element and suspension rod, steel wire rope does not have ductility yet, so another pectinid door is now
Can not open, even a little gap does not have yet.Avoiding problems the problem pushing air door by sheer good luck open of workman's presence.
The control valve clever structure of this structure setting, eliminates any redundancy seam bringing above suspension rod using pendulum
Gap.
