Description
Technical field
The utility model relates to a kind of mine ventilation safety device, relates in particular to bank at the bottom of a kind of linked-type air door.
Background technology
In the ventilation system, air door is one of main ventilation equipment under the coal mine, and the passage that connects between the main air entering and returning lane must be installed the above air door facility of twice with the connection roadway that is connected the air entering and returning tunnel.At present, the air door sill that mine is used has rubber-sole bank and the husky ash of cement end bank etc., though the rubber-sole bank is Reusability repeatedly, but cost is higher, be unfavorable for carrying out of " two carry one falls " work, the compliance of the husky ash of cement end bank is bad, is easy to fragmentation after the collision of process object and winch rope rub back and forth, need often maintenance, again make, the Anti-air-leakage effect is undesirable.
No matter install and use the air door sill of which kind of material, the frequent switch of air door and the collision of vehicle have larger impact to the Anti-air-leakage effect of air door sill, if select improper or install and use safeguard not in place, all might cause larger leaking out, affect the ventilation quality of mine, be unfavorable for the safety in production of mine, even cause heavy economic losses for colliery enterprise.
Summary of the invention
The purpose of this utility model provides bank at the bottom of the good linked-type air door of a kind of result of use, and this air door sill can improve air door facility quality, reduces air door sill and leaks out, and improves effective of wind amount rate, guarantees the stable of ventilation system.
For achieving the above object, the technical solution adopted in the utility model is:
Bank at the bottom of a kind of linked-type air door comprises base, is hinged with end bank above the base, it is characterized in that: the base front side is fixedly connected with fixed head, the fixed head front end is hinged with connecting rod, and a connecting rod wherein end is hinged with the air door drive link, and the connecting rod other end is hinged with connecting rod; The air door drive link other end is fixedly connected with air door transmission hook, has perforation on the base, and the air door drive link passes in boring a hole, and air door transmission hook is positioned at the base rear side; The connecting rod other end and Di Kan are hinged and connected; Be fixedly connected with spring between fixed head rear end and the connecting rod front end or between fixed head rear end and the connecting rod other end.
According to bank at the bottom of the described linked-type air door, it is characterized in that: above the described base by bank of the hinged described end of folding.
According to bank at the bottom of the described linked-type air door, it is characterized in that: described connecting rod is hinged and connected by being connected iron block with bank of the described end.
The utility model and air door combine as a whole, during open air door, and the air door drivening rod, connecting rod drives end bank, makes end bank flat, and air door is opened, and pedestrian or vehicle can pass through.After pedestrian or vehicle passed through, connecting rod drove folding, made end bank hold up, and played the effect of air door sill.The utility model can prevent that air door from leaking out, and makes things convenient for again pedestrian and vehicle to pass through, and can improve the effective of wind amount rate of mine, and result of use is good.
Description of drawings
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is plan structure schematic diagram of the present utility model;
Fig. 3 is left TV structure schematic diagram of the present utility model.
In the accompanying drawing:
