Description
Technical field
This utility model relates to mining equipment technical field, specifically, relates to a kind of mine air door interlock, uses
In preventing two air doors from opening simultaneously, cause Air escape branch.
Background technology
In order to ensure downhole safety produce ventilation equipment must be installed, air door is the one of ventilation equipment, it be exclusively for
Underworkings pedestrian, driving and arrange, to prevent Air escape branch, it is ensured that pedestrian, driving time, do not affect whole ventilating system
Properly functioning.The main air door of general down-hole is two and cooperates and install and use, and coordinates the twice air door installed not allow
Opening simultaneously, first open together when pedestrian or driving, another road is closed, and after pedestrian or car pass through, shuts this
After air door, just can open another road air door and pass through, so not result in Air escape branch.But beat while there are still artificially
The possibility opened.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 installation
The mutual locking of twice air door.Twice air door is respectively mounted blocking device, 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.

Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings:
See Fig. 1,2.
Embodiment one: see Fig. 1.
The utility model discloses a kind of mine air door interlock, including two sleeves being fixed together side by side 1, respectively
All being set with the slide block 2 matched in sleeve 1, the top of two slide blocks 2 is connected with the air door connecting strand 3 of both sides respectively, and two
Being provided with connecting plate 4 between individual sleeve 1, described connecting plate 4 is hinged with wobble lock block 5, described wobble lock block 5 passes through bearing pin
Being connected with connecting plate 4 and swing around bearing pin, described wobble lock block 5 is up big and down small and its upper surface width is more than outside two slide blocks
The minimum range on surface, when wherein the slide block of side pulls out in sleeve, wobble lock block be rocked to opposite side slide block upper
Side.In Fig. 1, the connecting strand 3 on the left side is connected with air door, not shown in air door figure, when air door is opened by air door directive wheel 12
Time, the slide block 2 on the left side is drawn out, and during pull-out, wobble lock block 5 is pushed up position shown in Fig. 1 by slide block 2, swings to the right,
The slide block 2 on right side is blocked so that it is can not pull out from sleeve 1 simultaneously.Owing to the length of air door connecting strand 3 is to beat according to air door
Length required during open and close conjunction is through measuring and calculating, and therefore, in this position, the air door on right side is limited in closed mode, no
Must open.
Described wobble lock block 5 is in funnel-form, and its lower surface is an inclined-plane, so, when slide block 2 skids off, it is possible to very
Backed down smoothly and make it swing to opposite side.
Two sleeves are connected and fixed by fixing transverse slat 6, and described fixing transverse slat 6 is provided with several fixing holes,
It is additionally provided with two spacing clamps 7 on the wooden partition side of described fixing transverse slat 6, is two sleeves between the spacing clamp of said two 7
Spacing draw-in groove.
Described fixing transverse slat 6 includes upper and lower two groups.
Embodiment two: see Fig. 2.
As one preferred embodiment, the bottom belt limited location boss 8 of described slide block 2, described upper cartridge inwall
Being provided with a limited step 9, the sliding stroke of described slide block is limited in sleeve 1 by positive stop lug boss 8 and limited step 9.So,
May insure that slide block 2 is not drawn out.
Alternatively preferred, the lower section of described slide block 2 is provided with returning pull-spring 10, the upper end of described returning pull-spring 10 with
The bottom of slide block 2 connects, and lower end is connected with the crossbeam 11 bottom sleeve 1.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
