Problems solved by technology
[0004] The purpose of the present invention is to provide a double anti-draft door that is convenient to control the air volume, so as to solve the problem that the currently used anti-draft door proposed in the above background technology cannot effectively control the air volume, is not convenient to use, and most of them are layered movable doors. When the mobile door body is severely deformed by the impact of the explosion, it cannot complete the isolation operation of the space on the front and rear sides of the lower frame, and cannot play a role in limiting the dangerous range.

The invention discloses a double anti-draft door which is convenient to control the air volume, which comprises a lower frame and a mounting plate. An installation cavity is reserved inside the lower frame, and a movable door body is mounted on the inside of the installation cavity. The upper end of the door body is provided with a connecting plate, and the inner side of the connecting plate is provided with a gear plate. The mounting plate is fixed on the top of the lower frame by welding, and the middle part of the mounting plate is equipped with a drive motor. The upper surface of the mounting plate The upper frame is fixed by welding, the inner end of the connecting rod is hingedly connected to the front and rear ends of the linkage plate, and the adjusting plate is hingedly connected to the outer end of the connecting rod. The double anti-draft door that is convenient to control the air volume can effectively control the air volume and is easy to use, and through the design of the double movable door body, the explosion mobile door body can be severely deformed when it is subjected to the impact of the explosion, and it can still complete the alignment of the front and rear sides of the lower frame The space isolation operation can effectively limit the dangerous range.
Description
technical field [0001] The invention relates to the technical field of anti-draft doors, in particular to a double anti-draft door which facilitates the control of air volume. Background technique [0002] The anti-sudden door is a kind of isolation equipment used to ensure the safety of operation in coal mining. The anti-sudden door can effectively reduce the problem of high-density accumulation of gas and reduce the occurrence of operational accidents. There are various anti-sudden doors currently used. But there are still deficiencies; [0003] For example, the anti-shock doors currently used cannot effectively control the air volume, are not convenient to use, and are mostly designed for layered movable doors. When the movable door body is severely deformed when it is impacted by an explosion, it cannot complete the isolation of the space on the front and rear sides of the lower frame. Therefore, the object of the present invention is to provide a double anti-draft door...
