Tunnel protection door with automatic opening and closing function

Abstract

The invention discloses a tunnel protection door with an automatic opening and closing function, and belongs to the technical field of tunnel protection door related technologies. An electric switch assembly and an automatic door opening and closing device are arranged on a hand wheel lock corresponding to the tunnel protection door, the electric switch assembly is utilized to realize automatic opening and closing of the hand wheel lock, and a door body can be opened or closed by utilizing the automatic door opening and closing door device. Automatic opening and closing of the tunnel protection door are achieved through the cooperation of the electric switch assembly and the automatic door opening and closing device. The tunnel protection door with the automatic opening and closing function is simple in structure and can be remotely controlled, and the door body can be effectively and rapidly opened or closed. By setting the priority level sequence of opening and closing control over the protection door and arranging an anti-pinch assembly and an resistance-meeting rebounding assembly, the use safety of the protection door can be greatly improved, the difficulty of door body control is reduced, the time for emergency evacuation through the tunnel protection door is shortened, the escape efficiency is improved, the operation safety of a tunnel is guaranteed, and the tunnel protection door is good in application and popularization value.

Description

technical field [0001] The invention belongs to the related technical field of tunnel protective doors, and in particular relates to a tunnel protective door with automatic opening and closing functions. Background technique [0002] With the continuous development of my country's high-speed railways, more and more railway tunnels are used, and the mileage is getting longer and longer. During the operation of the tunnel, due to the relatively closed space in the tunnel, it is difficult to deal with a fire in the tunnel, and the evacuation and rescue work of personnel is more difficult than in non-tunnel sections. Therefore, evacuation passages are often added in the tunnel to ensure the efficiency of emergency evacuation, and corresponding tunnel protective doors are set to separate the evacuation passages and the train track area of ​​the tunnel. [0003] However, due to the large ratio of the cross-sectional area of ​​the train to the cross-sectional area of ​​the tunnel ...

AI Technical Summary

Problems solved by technology

Because the door body of the tunnel protective door is heavy, it is difficult to push and pull, time-consuming and laborious, and the locking of the handwheel lock needs the door body to be ready in place, so as to align the shrinkage hole and complete the locking; therefore, the existing tunnel protective door It is very cumbersome to open or close, and there are great limitations. Once an emergency occurs in the tunnel and emergency evacuation is required, because the opening and closing of the tunnel protective door takes a lot of time, the efficiency of escape will often be greatly reduced, resulting in unnecessary evacuation. The loss is also not conducive to the safe operation of the tunnel
