Abstract
The utility model relates to a balancing air door, which is composed of two door leaves arranged in a roadway, the two door leaves are opened towards different directions. A door opening device for opening the two door leaves synchronously and a door closing device for closing the door leaves automatically are arranged on the door leaves. The door opening device is composed of two air door curved booms and a balancing rod. The air door curved booms are arranged on the same sides of the two door leaves respectively, and two ends of the balancing rod are hinged to the two air door curved booms respectively. The door closing device is composed of a pulley group, a steel wire rope and a counter weight. One end of the steel wire rope is fixedly connected with the back of the opening direction of one door leaf, the pulley group is pre-embedded in the roadway of the back of the door leaves, and the other end of the steel wire rope penetrates through the pulley group to be connected with the suspended counter weight. The balancing air door can guarantee that the two door leaves can be opened in place towards different directions synchronously. The corresponding counter weight is arranged so as to guarantee that the air door can be closed automatically. The balancing device not only improves conditions for mine operation and ventilation but also provides guarantee for a safe and reliable mine ventilation system.
Description
Technical field
The utility model 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 the utility model provides a kind of balance air door, has solved the problem of door opening difficulty, and this device is solid reliable, multiple functional, installs simple, easy to maintenance.
The technical scheme that the utility model is taked is: 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.。
The balance air door that the utility model provides; 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.
