Explosion-proof air door for mine
The invention discloses an anti-explosion air door for a mine. The anti-explosion air door comprises a door frame, an air door body, an auxiliary door plate, an electromagnetic attraction structure, two telescopic limiting structures and two reset parts. The door frame is slidably arranged in a mine laneway. The air door and the auxiliary door plate are rotationally connected with the door frame; the telescopic limiting structure comprises a limiting frame, a connecting lug and a sliding rod; placing grooves are formed in the two sides of the roadway, and the sliding rods are horizontally arranged in the placing grooves; the limiting frame penetrates through the outer side of the door frame and is fixedly connected with the connecting lugs. The limiting frame extends into the end of the door frame to clamp the side face of the air door. The connecting lug penetrates through the sliding rod and can obliquely slide in the length direction of the sliding rod; the reset piece is arranged in the roadway; the electromagnetic attraction structure is arranged on the outer side of the auxiliary door plate. According to the device, when explosion occurs in a roadway, the air door can be automatically opened for pressure relief, after explosion is finished, the air door can be automatically closed to be in a locked state, the air door is prevented from being damaged, the air door can be continuously used, it is guaranteed that the air door still has the function of partition ventilation subsequently, and the cost is reduced.
本申请公开了一种矿井用防爆风门，包括门框、风门、辅助门板、电磁吸合结构、两个伸缩限位结构和两个复位件；门框滑动设置于矿井巷道内；风门和辅助门板与门框转动连接；伸缩限位结构包括限位架、连接耳和滑杆；巷道两侧开设有放置槽，滑杆水平设置于放置槽中；限位架贯通门框外侧并与连接耳固定连接，限位架伸入门框的端部将风门侧面卡接；连接耳贯通滑杆，能够沿着滑杆的长度方向倾斜滑动；复位件设置于巷道内；电磁吸合结构设置于辅助门板外侧。本申请实现了巷道内发生爆炸时，风门能够自动打开进行泄压，在爆炸结束后，风门能够自动关闭至锁紧状态，避免了风门被损坏，风门能够继续使用，保证了后续仍然具有的隔断通风的功能，降低了成本。
