According to described mining parallel push-and-pull throttle, it is characterized in that: be fixedly connected with threshold between the described left and right door frame, threshold is positioned at the doorjamb lower end, has the chute that opening makes progress in the middle of the threshold, and described door leaf is slidingly connected in the chute.
According to described mining parallel push-and-pull throttle, it is characterized in that: described door leaf lower edge is connected with guide strip, and the chute of guide strip and described threshold is slidingly connected.
According to described mining parallel push-and-pull throttle, it is characterized in that: be connected with wire rope above the described door leaf, the other end of wire rope is connected with attached bob thing, and wire rope links to each other with door leaf, attached bob thing by hauling block.
According to described mining parallel push-and-pull throttle, it is characterized in that: the described Men Liangshang of hanging is hung with the described door leaf of two fans.
According to described mining parallel push-and-pull throttle, it is characterized in that: described door leaf edge is equipped with weather strip.
According to described mining parallel push-and-pull throttle, it is characterized in that: have form on the described door leaf.
Door leaf of the present invention changes the push-and-pull switching into by present flat opening, saved the occupation space of opening the door, and simple in structure, convenient maintenance and replacement, switch are convenient, have thoroughly solved under the coal mine problem of difficult because the too big air door of blast opens the door, and make the easy and convenient air door that passes through of pedestrian and vehicle.
Description of drawings
Fig. 1 is a structural representation of the present invention.
In the accompanying drawing:
1, hangs pulley 2, wire rope 3, door upper ledge 4, hauling block
5, hang a beam 6, doorjamb 7, threshold 8, door leaf
9, guide strip 10, weather strip 11, form 12, attached bob thing
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is further described:
A kind of mining parallel push-and-pull throttle, as shown in Figure 1, comprise a upper ledge 3, doorjamb 6 and door leaf 8, door upper ledge 3 is fixedlyed connected with doorjamb 6, on the door leaf 8 handle is installed, be fixedly connected with between the left and right door frame 6 and hang a beam 5, hang to slidely connect on the beam 5 and hang pulley 1, hang pulley and be hung with door leaf 81 time.Be fixedly connected with threshold 7 between the left and right door frame 6, threshold 7 is positioned at doorjamb 6 lower ends, has the chute that opening makes progress in the middle of the threshold 7, and door leaf 8 is slidingly connected in the chute.Door leaf 8 lower edges are connected with guide strip 9, and guide strip 9 is slidingly connected with the chute of threshold 7, can prevent the door leaf sideslip, indeformablely when guaranteeing that the door leaf obverse and reverse is subjected to external force and is subjected to blast do not open, and only just can open when door leaf is subjected to horizontally-sliding power.Be connected with wire rope 2 above the door leaf 8, the other end of wire rope 2 is connected with attached bob thing 12, and wire rope 2 links to each other with door leaf 8, attached bob thing 12 by hauling block 4.In the present embodiment, hang be hung with on the beam 5 two the fan door leafs 8.Door leaf 8 edges are equipped with weather strip 10.Have form 11 on the door leaf 8.
Embodiment recited above is described preferred implementation of the present invention; be not that design of the present invention and scope are limited; under the prerequisite that does not break away from design concept of the present invention; common engineers and technicians make technical scheme of the present invention in this area various modification and improvement; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection all is documented in claims.
Hang the effect that a beam 5 plays guide rail among the present invention.
Now because blast is too big, even if open the release window, it is still very difficult that people opens the door, and often just hits door with coal car as car through out-of-date workman, install this reality novel after, pedestrian or driving are very light through out-of-date air door switch, have solved the problem that it is difficult that the workman opens the door, and make workman and the vehicle pass through air door rapidly, improved operating efficiency, alleviated working strength of workers, prolonged the application life of air door, the while is simple in structure, installation and maintenance are convenient and swift.
When the present invention installs that door leaf is hidden in the door buttress, can avoid vehicular traffic to scratch like this.Perspective window on the door leaf, convenient under special circumstances situation of observing the inside and outside tunnel of air door.The wind comes from sealing effectiveness that keeps out the wind of this air door both forward and reverse directions is the same, does not need to install door for air reversing again, and installation and maintenance are convenient, reduced installation and maintenance intensity and cost, and this air door good sealing effect, and are elegant in appearance.
Door upper ledge, doorjamb among the present invention, hang a beam, threshold and make of channel-section steel or square tube (or shaped steel), the door leaf covering of the fan is made of 3mm steel plate or other sturdy material, form is opened in the door leaf middle and upper part, and the door leaf corner prevents to leak out with rubber moccasin or rubber strip sealing.Above hanging a beam, one group of pulley is installed, and is connected two pectinid doors, make two pectinid doors realize interlock, and switch is synchronous with seizing wire.Load onto at the other end of wire rope and to weigh down bucket, realize that air door opens after the pedestrian passes through, do not having to close automatically under the situation of external force (also can change spring into, to realize close the door automatically) weighing down bucket.
The present invention has been arranged, the wind comes from and reverse side all can not blow door leaf open when the wind comes from when the front, so do not need to be provided with reverse throttle, only this gets final product together again.
