Movable threshold of tunnel protective door
The invention discloses a movable doorsill of a tunnel protective door, and relates to the field of protective doors, the movable doorsill comprises a door frame and a door body, the lower part of the door frame is provided with a lifting groove and a movable doorsill, the lower part of the door frame is also provided with a transmission assembly, the transmission assembly comprises a first plug cylinder and a second plug cylinder, the lower part of the side wall of the door frame is provided with a mounting groove, and a first piston is slidably arranged in the first plug cylinder; a first contact block is arranged at one end of the first connecting rod, a second piston is slidably arranged in the second plug barrel, a second connecting rod is arranged on one side of the second piston, a second abutting block is arranged at one end of the second connecting rod, and the first plug barrel communicates with the second plug barrel through a connecting pipe. And hydraulic oil is arranged in a communicated space between the first plug barrel and the second plug barrel. Power is transmitted through hydraulic pressure, resistance caused to closing of the door body can be reduced, and the movable threshold can be adjusted after being abraded, so that the movable threshold does not sink after descending.
本发明公开了隧道防护门活动门槛，涉及防护门领域，包括门框和门体，门框的下部设有升降槽和活动门槛，门框的下部还设有传动组件，传动组件包括第一塞筒和第二塞筒，门框的侧壁下部设有安装槽，第一塞筒内滑动设置有第一活塞，第一连接杆的一端设有第一接触块，第二塞筒的内部滑动设置有第二活塞，第二活塞的一侧设有第二连接杆，第二连接杆的一端设有第二抵触块，第一塞筒和第二塞筒之间通过连接管连通，第一塞筒和第二塞筒之间连通的空间内设有液压油。本发明通过液压传递动力，能够降低给门体关闭造成的阻力，在活动门槛磨损后能够进行调节，使得活动门槛在下降后不会出现凹陷的情况。
