Abstract
The invention relates to a balance air door which is composed of two door leaves installed in a roadway, wherein the two door leaves are opened towards different directions; a door opening device for synchronously opening the two door leaves and a door closing device for automatically closing the door leaves are arranged on the door leaves; the door opening device consists of two air door curved arms and a balance rod, the air door curved arms are respectively installed at the same side of the two door leaves, and two ends of the balance rod are respectively hinged with the two air door curved arms; and the door closing device consists of a pulley block, a steel wire rope and a balance weight, one end of the steel wire rope is fixedly connected to the backside of the opening direction of one door leaf, the pulley block is pre-embedded in the roadway on the backside of the door leaf, the other end of the steel wire rope penetrates through the pulley block to be connected with the suspended balance weight, so that the balance air door provided by the invention can ensure that the two air leaves can be synchronously opened in place, and the corresponding balance weight is arranged to ensure that the air door can be closed automatically. Through using the balance air door, not only can the mine working and ventilation conditions be improved, but also a guarantee can be provided for the security and reliability of a mine ventilation system.
Description
Technical field
The invention of this reality relates to a kind of device of mining balance air door, is used for the incorgruous synchronous unlatching of air door.
Background technology
Mine ventilation is the next important link of coal mine, and reliable, the stable relation of air quantity is to the safety of mine, and air door is the indispensable ingredient in this link.
Mine air door is a kind of ventilation system under all big-and-middle-sized coal mine that is used for, and in actual use, the door opening difficulty occurred, and the serious problem of leaking out causes distinguished and admirable short circuit, directly influences the normal safe ventilation in down-hole.
Summary of the invention
The purpose of this invention is to provide a kind of balance air door, solved the problem of door opening difficulty, this device is solid reliable, multiple functional, installs simple, easy to maintenance.
The technical scheme that the present invention taked is: a kind of balance air door; Door leaf by being installed in the incorgruous unlatching of the fan of two in the tunnel is formed; The door opener and the closing device that is used for the auto-closing door leaf that are used for opening synchronously two fan door leafs are installed on door leaf; Said door opener is made up of two air door curved booms and a balancing pole, and said air door curved boom is installed in the homonymy of two fan door leafs respectively, and the two ends of balancing pole are hinged with two air door curved booms respectively; Said closing device is made up of assembly pulley, wire rope and counterweight, and an end of wire rope is fixedly connected on the back side of Yishanmen fan opening direction, on the tunnel at the door leaf back side, is embedded with assembly pulley, and the other end of wire rope passes assembly pulley, is connected with the counterweight of suspention.
Further, described assembly pulley is made up of second pulley that is fixed on the top, tunnel, makes first pulley of wire rope horizontal movement and is installed in the tunnel sidewall, wire rope is moved both vertically.。
A kind of balance air door provided by the invention; Can guarantee that two fan doors are incorgruous reaches the position synchronously, and is provided with corresponding counterweight, can close automatically to guarantee air door; Use this bascule not only to improve mine operation, ventilation condition, and assurance is provided for mine ventilation system safe and reliable.
Description of drawings
Fig. 1 is the structural representation of a kind of balance air door of the present invention.
