Compression-resistant door frame structure, underground roadway air door and mounting method
The invention provides a compression-resistant door frame structure, an underground roadway air door and an installation method, and relates to the technical field of coal mine underground roadway air doors. The compression-resistant door frame structure comprises a movable frame, an air door frame and a deformation-resistant structure; the air door frame is located in the first mounting cavity and movably connected with the guide groove in the depth direction of the guide groove, and a movable area is defined between the outer peripheral wall of the air door frame and the inner peripheral wall of the guide groove; the anti-deformation structure is mounted in the movable area, has a first critical state and a second critical state, and can be switched from the first critical state to the second critical state to generate elastic deformation when the movable door frame moves relative to the air door frame; the anti-deformation structure can be switched from the second critical state to the first critical state to rebound so as to drive the movable frame and the air door frame to reset. The device can deform when being subjected to external pressure, can automatically recover to the initial shape when the external pressure is released, and is good in structural stability.
本发明提供一种抗压门框结构、井下巷道风门和安装方法，涉及煤矿井下巷道风门技术领域，包括活动边框、风门门框和抗变形结构，活动边框围绕成型有第一安装腔且具有导向槽，风门门框位于第一安装腔内并与导向槽沿导向槽的深度方向可移动地相连，风门门框的外周壁与导向槽的内周壁间限定出活动区；抗变形结构安装于活动区且具有第一临界状态和第二临界状态，抗变形结构能够在活动门框相对风门门框移动时由第一临界状态切换至第二临界状态以发生弹性变形，抗变形结构能够由第二临界状态切换至第一临界状态回弹以驱动活动边框和风门门框复位。本发明能够在受到外部压力时发生形变，而在外部压力释放时又可自动恢复初始形状，结构稳定性好。
