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 [0001] The invention relates to a device for a mine-used balance damper, which is used for synchronous opening of the dampers in different directions. Background technique [0002] Mine ventilation is a very important link in coal mines. The reliability and stability of the air volume is related to the safety of the mine, and the damper is an indispensable part of this link. [0003] Mine damper is a kind of underground ventilation system used in all large and medium-sized coal mines. In the actual use process, the damper is difficult to open and the air leakage is serious, resulting in a short circuit of the air flow, which directly affects the normal safe ventilation of the mine. Contents of the invention [0004] The object of the present invention is to provide a balance damper, which solves the problem of difficulty in opening the damper. The device is solid and reliable, has complete functions, is simple to install, and is convenient to maintain....
