Abstract
The invention provides a linked air door bottom threshold, which comprises a base, wherein a bottom threshold is hinged on the base, the front side of the base is fixedly connected with a fixing plate, the front end of the fixing plate is hinged with a connecting rod, one end of the connecting rod is hinged with an air door transmission rod, the other end of the connecting rod is hinged with a connecting rod, the other end of the air door transmission rod is fixedly connected with an air door transmission hook, a through hole is formed in the base, the air door transmission rod passes through the though hole, the air door transmission hook is positioned at the back side of the base, the other end of the connecting rod is hinged and connected with the bottom threshold, and a spring is fixedly connected between the back end of the fixing plate and the front end of the connecting rod or between the back end of the fixing plate and the other end of the connecting rod. The upper side of the base is hinged with the bottom threshold through a hinge. The connecting rod and the bottom threshold are hinged and connected through a connecting iron block. The linked air door bottom threshold is connected into a whole with an air door, when the air door is opened, the air door drives the connecting rod, and the connecting rod drives the bottom threshold, so the bottom threshold is flatly turned, the air door is opened, and pedestrians or vehicles can pass. After the pedestrians and the vehicles pass the air door, the connecting rod drives the hinge, so the bottom threshold stands up, and the air door bottom threshold effect is realized.
Description
Technical field
The present invention relates to a kind of mine ventilation safety device, relate in particular to bank at the bottom of a kind of linked-type air door.
Background technology
Under coal mine, in ventilation system, air door is one of main ventilation equipment, and the passage that connects between main air entering and returning lanes must be installed the above air door facility of twice with the connection roadway that is connected the air entering and returning tunnels.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, cause heavy economic losses even for colliery enterprise.
Summary of the invention
The purpose of this invention is to provide bank at the bottom of the good linked-type air door of a kind of result of use, 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 used in the present invention is:
Bank at the bottom of a kind of linked-type air door comprises base, is hinged with end bank above 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 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 connecting rod front end or between fixed head rear end and the connecting rod other end.
According to bank at the bottom of described linked-type air door, it is characterized in that: above described base by folding bank of the hinged described end.
According to bank at the bottom of 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 present invention 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 present invention can prevent that air door from leaking out, and facilitates again pedestrian and vehicle to pass through, and can improve the effective of wind amount rate of mine, and result of use is good.
