Abstract
The invention discloses an automatic integral interlocking device for coal mine air doors. The automatic integral interlocking device for the coal mine air doors comprises an interlocking pin (1), spring seats (1a), bolts (1b), compression springs (2), an integral mounting rack (3), a lower portion (3a), an upper portion (3b), mounting holes (3c), sleeves (4), bolt guide holes (4a), long cylindrical counter weights (5), cones (5a), pulling rope bolt rings (6), pulley assemblies (7), pulling ropes (8) and a bolt assembly (9). The automatic integral interlocking device for the coal mine air doors can enable interlocking of two air doors to be reliable, can be used for a long time, and is simple in structure, particularly convenient to mount underground, suitable for various work sites and capable of guaranteeing normal working of a ventilation system.
Description
Technical field the present invention relates to the air door automatic integral interlocking device of ventilation system under a kind of coal mine
The underground air door in the present colliery of technical background for solve in positive and negative aweather two kinds of situations every wind commutation problem, the interlock that adopts is complicated, is difficult for installing, and works also unreliable, very easily cause the twice air door to open simultaneously and produce and leak out, destroyed the normal operation of ventilation system.
Summary of the invention the objective of the invention is: provide a kind of simple in structure, the interlocking reliable operation is easily installed, and can be guaranteed the air door automatic integral interlocking device that air door does not leak out.
Technical scheme of the present invention is: comprise interlocking device, compressing spring, the integral installation frame, sleeve, the long cylinder weight, pull rope bolt ring, pulley assembly, pull rope, the coal mine ventilation door automatic integral interlocking device that the bolt assembly forms, taper dead bolt (1b) about at 45 ° two of interlocking plunger (1) processing, be processed with a large spring base (1a) of ratio dead bolt (1b) diameter that compressing spring (2) is installed in the middle of it, a sleeve (4) vertically equidistantly respectively is welded on the both sides of integral installation frame (3), the upper inner of two sleeves (4) is processed with the dead bolt pilot hole (4a) of interlocking plunger (1), behind upper each the concentric compressing spring of suit (2) of two ends dead bolt (1b), the dead bolt on the left side (1b) be encased in movingly with one heart the dead bolt pilot hole (4a) of left side sleeve (4) inner after, again the dead bolt on the right (1b) is encased in the dead bolt pilot hole (4a) of the right sleeve (4) with one heart movingly inner.A vertical concentric long cylinder weight (5) movingly respectively is installed in the sleeve (4), and about 45 ° bullet (5a) of certain-length is processed in the upper end of long cylinder weight (5).The pull rope bolt ring (6) of length adjustable is installed in the middle of the bullet (5a) of long cylinder weight (5), the dead bolt (1a) on interlocking plunger (1) both sides is pushed up on the bullet (5a) that is pressed in long cylinder weight (5) movingly.The total length of interlocking plunger (1) is the twice that the inner side edge distance of two elongated cylinder weights (5) adds long cylinder weight (5) and sleeve (4) gap, adds the total length sum of safety locking.The bottom (3a) of integral installation frame (3), top (3b) fixedly mount with bolt assembly (9), pulley assembly (7) is installed on the top (3b), the center line of pulley assembly (7) and sleeve (4) are concentric, are processed with several installing holes (3c) on bottom (3a) and top (3b).
The invention has the beneficial effects as follows: can make twice air door interlocking reliable operation, can use for a long time, simple in structure, it is convenient especially to install in the down-hole, and applicable various working sites can guarantee the ventilation system normal operation.
Description of drawings Fig. 1 is that the A-A of the present invention Fig. 3 that another road air door is automatically locked when one door opening dissects front view; Fig. 2 is the schematic diagram that the present invention closes simultaneously at the twice air door; Fig. 3 is the left view of Fig. 1; Fig. 4 is the B place enlarged diagram among Fig. 1.
Part sequence number is as follows among the figure: interlocking plunger (1), spring base (1a), dead bolt (1b); Compressing spring (2); Integral installation frame (3), bottom (3a), top (3b), installing hole (3c); Sleeve (4), dead bolt pilot hole (4a); Long cylinder weight (5), bullet (5a); Pull rope bolt ring (6); Pulley assembly (7); Pull rope (8); Bolt assembly (9).
Specific embodiment the present invention such as Fig. 1,2,3, in 4 illustrated embodiments, respectively loading onto pull rope (8) on the pull rope bolt ring (6) in mounted the present invention, and the other end of two pull ropes (8) respectively contacts with air door, after opening such as Fig. 1 one sect, driving long cylinder weight (5) through pull rope (8) upwards rises, because the bullet (5a) of long cylinder weight (5) promotes the dead bolt (1b) of interlocking plunger (1) to one side, thereby makes the another side dead bolt (1b) of interlocking plunger (1) suppress the bullet (5a) of another long cylinder weight (5) and make another sect by automatic locking.
