Abstract
The utility model relates to safety control equipment for underground air door in a coal mine, particularly an air door interlocking device which solves the problems that external power source is needed, components are not tightly matched, and the safety is bad, which exist in the prior art. The air door interlocking device comprises pulleys fixed on the wall of a tunnel, a pull rope which passes round the pulleys respectively and is connected to the air door, a swing pipe connected with the other end of the pull rope, and sleeve pipes for placing the swing pipe, wherein the two sleeve pipes are connected through a connecting plate, the corresponding position of the connecting plate, which is above the sleeve pipes, is provided with a shaft hole and a rotating shaft penetrates through an interlocking piece and penetrates through a shaft hole. The utility model has the advantages of simple structure, easy installation and no need of the external power source. When the sleeve pipes are buried underground, the complete equipment is firm and safe.
Description
Technical field
The utility model relates to a kind of coal mine lower wind door security control equipment, specifically is a kind of air door interlock.
Background technology
Under coal mine in the ventilation system, air door be cut off under the mine, outgoing airflow, but again can the current a kind of facility of guarantor's car.According to the ventilation safety quality specifications, one group of air door needs to install the twice air door at least, and people's car by the time can not open simultaneously.Mainly containing utilization in the prior art is the pneumatic door lock of power with the down-hole blast, is the electric locking of power with the down-hole power, equipment such as wheeled backguy locking.These equipment mostly need power sources such as extraneous wind or electricity, and utilizing pulley and backguy to push with the people is that powered device structurally takes backguy directly to be connected with air door, and major part all exists parts to cooperate defective tightness, the problem of poor stability.
Summary of the invention
The utility model is in order to solve the external power source that needs that exists in the prior art, and parts cooperate defective tightness, the problem of poor stability and a kind of air door interlock is provided.
The utility model is realized by following technical scheme, a kind of air door interlock, and it comprises the pulley that is fixed on the wall of tunnel, walks around pulley respectively and is connected in stay cord on the air door, is connected the swing pipe of the stay cord other end, places the sleeve pipe of swing pipe.Two sleeve pipes connect by junction plate, and the corresponding position that is higher than sleeve opening has axis hole on the junction plate, and rotating shaft is passed locking part and penetrated axis hole.
In actual the use, two air doors connect backguy respectively, and the length of adjusting stay cord the locking part opening is upwards when two air doors are closed.The sleeve pipe of two connections is imbedded the underground certain depth, stay cord was pulled when one of them air door was open, and swing pipe is pulled up, and stirred locking part simultaneously and turned to another side and block the another set of mouth of pipe, hindered the motion of another swing pipe, this moment, another air door then can not be opened.Otherwise, when another air door is opened, will limit the unlatching of last air door.
Compared with prior art, the utility model is simple in structure, and is easy for installation, need not external power source, sleeve pipe imbedded underground can make complete equipment more firm, safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
A kind of air door interlock is fixed with two groups at the top, tunnel, and every group has two fixed pulleys 1 respectively, twice air door 2 is installed in the mine laneway, is connected to stay cord 3 on each air door respectively, two fixed pulleys are walked around in backguy, the stay cord other end is connected to swing pipe 4, places the sleeve pipe 5 of swing pipe.Two sleeve pipes are by junction plate 6 welding, and the corresponding position that is higher than sleeve opening has axis hole on the junction plate, and rotating shaft is passed locking part 7 and penetrated axis hole.The doorframe of air door is passed in backguy.
Locking part 7 is the font, and locking part can be made of the vertical welding of two reinforcing bars.
The drift angle place cross-under of locking part has rotating shaft, and rotating shaft penetrates in junction plate 6 axis holes.
The underground in tunnel is imbedded in two sleeve pipe 5 bottoms, to play effect stable and that reinforce.
Claims (2)
1, a kind of air door interlock, it comprises the pulley (1) that is fixed on the wall of tunnel, walk around pulley respectively and be connected in stay cord (3) on the air door (2), be connected the swing pipe (4) of the stay cord other end, place the sleeve pipe (5) of swing pipe, it is characterized in that two sleeve pipes (5) connect by junction plate (6), corresponding sleeve pipe (5) position suitable for reading that is higher than has axis hole on the junction plate, and rotating shaft is passed locking part (7) and penetrated axis hole.
