Abstract

The invention provides a combined air door, which comprises a door frame, two oppositely opened door leaves arranged in the door frame, and a connecting rod mechanism used for driving the two door leaves to open to the opposite directions respectively, wherein each of the door leaves comprises two plank layers, and a windproof interlayer arranged between the plank layers, and the plank layers and the windproof interlayer are fixedly connected to form a whole body. According to the combined air door provided by the invention, through the windproof interlayer, air leak of the door leaves can be effectively prevented, and the door leaves are light and easy to be controlled to open and close, the combined air door is suitable for a large roadway, and can adapt to influence caused by deformation of the roadway.

Description

technical field [0001] The invention relates to the technical field of coal mine equipment manufacturing, in particular to a combined damper. Background technique [0002] The mine damper type is an important ventilation facility to ensure the stability of the coal mine underground ventilation system. It is used to block the flow of wind in the roadway, and at the same time to meet the passage of staff and coal mining equipment. [0003] The mine damper generally includes a door frame fixedly embedded on the roadway wall pile and a door leaf hinged on the door frame. In the prior art, the door leaf is generally an integrated structure such as iron or compressed material or a wooden board spliced ​​structure. [0004] figure 1 It is a schematic diagram of the door leaf structure assembled by planks in the prior art; figure 1 As shown, the door leaf includes a plurality of wooden planks 10 arranged in parallel, and the plurality of wooden planks 10 are combined to form a doo...
