Abstract
The invention relates to the technical field of mining equipment, in particular to a mining air door interlocking device. The mining air door interlocking device comprises two sleeves which are fixed together side by side, each sleeve is internally provided with a sliding block in a sleeving mode, the sliding blocks are matched with the sleeves, the upper portions of the two sliding blocks are connected with air door connection cables on the two sides respectively, a connection plate is arranged between the two sleeves, a swinging locking block is hinged to the connection plate, and the swinging locking block is connected with the connection plate through a hinge pin and swings around the hinge pin. The swinging locking block is big at the upper end and small at the lower end, and the width of the upper surface of the swinging locking block is larger than the minimum distance of the outer surfaces of the two sliding blocks. When the sliding block on one side is pulled out of the sleeve, the swinging locking block swings to the position above the sliding block on the other side. One-time interlocking of two air doors is effectively achieved, and to avoid the situation that the two air doors are opened at the same time and ensure normal ventilation to avoid air current short circuit, the installed two air doors shall be interlocked.
Description
Technical field
The present invention relates to mining equipment technical field, specifically, relate to a kind of mine air door interlock, be used for preventing two air doors from opening simultaneously, cause Air escape branch.
Background technology
Must install ventilation equipment to ensure that downhole safety produces, air door is the one of ventilation equipment, and it is arranged exclusively for underworkings pedestrian, driving, to prevent Air escape branch, it is ensured that when pedestrian, driving, do not affect the properly functioning of whole ventilating system.The main air door of general down-hole is two and cooperates and install and use, coordinate the twice air door installed not allow to open simultaneously, first open together when pedestrian or driving, another road is closed, after pedestrian or car pass through, after shutting this air door, just can open another road air door and pass through, so not result in Air escape branch.But the possibility opened while there are still artificially.In order to avoid twice air door is opened simultaneously, it is ensured that normally ventilate in order to avoid causing Air escape branch, it is necessary to realize the mutual locking of twice air door installed.Being respectively mounted blocking device on twice air door, when opening one air door, then another road automatic blocking, only after the air door opened is closed, another road air door could be opened.Therefore the interlock between air door has been invented.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, adapt to reality need, it is provided that a kind of mine air door interlock.
In order to realize the purpose of the present invention, the technical solution used in the present invention is:
A kind of mine air door interlock, including two sleeves being fixed together side by side, the slide block matched all it is set with in each sleeve, the top of two slide blocks is connected with the air door connecting strand of both sides respectively, it is provided with connecting plate between two sleeves, wobble lock block it is hinged with on described connecting plate, described wobble lock block is connected with connecting plate by bearing pin and swings around bearing pin, described wobble lock block is up big and down small and its upper surface width is more than the minimum range of two outside face thereof, when wherein the slide block of side pulls out in sleeve, wobble lock block be rocked to opposite side slide block top.
The bottom belt limited location boss of described slide block, described upper cartridge inwall is provided with a limited step, and the sliding stroke of described slide block is limited in sleeve by positive stop lug boss and limited step.
The lower section of described slide block is provided with returning pull-spring, and the upper end of described returning pull-spring is connected with the bottom of slide block, and lower end is connected with the crossbeam of sleeve bottom.
Described wobble lock block is funnel-form.
Two sleeves are connected and fixed by fixing transverse slat, and described fixing transverse slat is provided with several fixing holes, and the wooden partition side of described fixing transverse slat is additionally provided with two spacing clamps, are the spacing draw-in groove of two sleeves between the spacing clamp of said two.
Described fixing transverse slat includes upper and lower two groups.
The beneficial effects of the present invention is:
Effectively avoid the once locking mutually achieving twice air door, it is to avoid twice air door is opened simultaneously, it is ensured that normally ventilate in order to avoid causing Air escape branch, it is necessary to realize the mutual locking of twice air door installed.
