Description
Technical field
The utility model relates to the automatic integral interlock device of air door of ventilation system under a kind of coal mine.
Technical background
At present the underground air door in colliery is in order to solve separated wind under the positive and negative aweather two kinds of situation problem that commutates; The interlock that is adopted is complicated, is difficult for installing, and it is also unreliable to work; Very easily cause the twice air door to open simultaneously and produce and leak out, destroyed the operate as normal of ventilation system.
Summary of the invention
The purpose of the utility model is: provide a kind of simple in structure, and the interlocking reliable operation, easy mounting, and can guarantee the automatic integral interlock device of air door that air door does not leak out.
The technical scheme of the utility model is: comprise the automatic integral interlock device of colliery air door that interlocking plunger, compressing spring, integral installation frame, sleeve, cylinders weight, pull rope bolt ring, pulley assembly, pull rope, bolt assembly are formed; Be processed into the taper dead bolt (1b) about 45 ° to two of interlocking plunger (1); Be processed with a big spring base (1a) of ratio dead bolt (1b) diameter that compressing spring (2) is installed wherein; The vertical equidistance sleeve (4) that 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 last each compressing spring of concentric suit (2) of two ends dead bolt (1b); After being encased in the dead bolt on the left side (1b) movingly dead bolt pilot hole (4a) lining of left side sleeve (4) with one heart, be encased in the dead bolt on the right (1b) movingly dead bolt pilot hole (4a) lining of the right sleeve (4) more with one heart.A vertical concentric cylinders 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 cylinders weight (5).The pull rope bolt ring (6) of adjustable length is installed in the middle of the bullet (5a) of cylinders weight (5), the dead bolt (1a) on interlocking plunger (1) both sides movingly roof pressure on the bullet (5a) of cylinders weight (5).The total length of interlocking plunger (1) is the twice that the inner side edge distance of two elongated cylinder weights (5) adds gap between cylinders weight (5) and the sleeve (4), adds the total length sum of safety locking.Bottom (3a), top (3b) of integral installation frame (3) 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 beneficial effect of the utility model is: 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, is suitable for various working sites, can guarantee the ventilation system operate as normal.
Description of drawings
Fig. 1 is that the A-A of the utility model Fig. 3 that another road air door is automatically locked when one door opening dissects front view; Fig. 2 is the sketch map that the utility model is closed at the twice air door simultaneously; 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); Cylinders weight (5), bullet (5a); Pull rope bolt ring (6); Pulley assembly (7); Pull rope (8); Bolt assembly (9).
The specific embodiment
In the utility model such as Fig. 1,2,3,4 illustrated embodiments; Be processed into the taper dead bolt (1b) about 45 ° to two of interlocking plunger (1); Be processed with a big spring base (1a) of ratio dead bolt (1b) diameter that compressing spring (2) is installed wherein; The vertical equidistance sleeve (4) that 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); After going up each compressing spring of concentric suit (2) to two ends dead bolt (1b), be encased in the dead bolt on the left side (1b) movingly dead bolt pilot hole (4a) lining of left side sleeve (4) with one heart after, be encased in the dead bolt on the right (1b) movingly dead bolt pilot hole (4a) lining of the right sleeve (4) more with one heart.A vertical concentric cylinders 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 cylinders weight (5).The pull rope bolt ring (6) of adjustable length is installed in the middle of the bullet (5a) of cylinders weight (5), the dead bolt (1a) on interlocking plunger (1) both sides movingly roof pressure on the bullet (5a) of cylinders weight (5).Bottom (3a), top (3b) of integral installation frame (3) 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).Respectively loading onto pull rope (8) on the pull rope bolt ring (6) on mounted the utility model; And the other end of two pull ropes (8) is respectively got in touch with air door; After opening like Fig. 1 one sect; Driving cylinders weight (5) through pull rope (8) upwards rises; Because the bullet (5a) of cylinders weight (5) promotes the dead bolt (1b) of interlocking plunger (1) to one side, thereby make the another side dead bolt (1b) of interlocking plunger (1) suppress the bullet (5a) of another cylinders weight (5) and another sect is pinned automatically.
