Abstract

The invention provides an inflating air door, which comprises a door frame and a door body. The door frame is fixed in a roadway in the cross section direction of the roadway, and the top of the doorframe is fixed to a roof of the roadway; the left side and the right side of the door frame are connected with coal sides on the two sides of the roadway correspondingly; the door body is arranged onthe front side or the rear side of the door frame, and one edge of the door body is connected with one edge of the door frame; the door body comprises a first sealing piece and a second sealing piecewhich are prepared from light materials; and the edge of the first sealing piece and the edge of the second sealing piece are connected in a sealed mode, an inflating space is formed between the firstsealing piece and the second sealing piece, and the interior of the inflating space is used for being filled with gas. According to the inflating air door, the door body is prepared from the light materials, the middle of the door body is filled with the gas, and thus mounting and transporting are convenient.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to an inflatable damper. Background technique [0002] The damper is an important structure in the mine ventilation system. It is generally installed in the return air lane and the air intake lane. It can block the air flow, create conditions for the on-demand distribution of mine air flow, and at the same time provide convenience for pedestrians and transportation. With the advancement of science and technology, the types of dampers are also increasing. According to the power source, they can be divided into manual dampers, electric dampers, electronically controlled hydraulic dampers, and electronically controlled pneumatic dampers. These dampers are generally composed of a fixed door frame and a single or double door body installed on the door shaft. Except for the manual damper, other types of dampers also include a control system for controlling the opening or closing of the doo...
