Problems solved by technology
[0003] However, due to the large ratio of the cross-sectional area of the train to the cross-sectional area of the tunnel when the train runs through the tunnel, and the length of the tunnel is often longer, the running speed of the train is faster, so that when the train runs in the tunnel, there will be relatively large The "piston effect" of large lateral wind pressure will produce continuous wind pressure on the tunnel protective doors on both sides of the tunnel. Under the action of long-term circulating wind pressure, the tunnel protective doors may be damaged by impact or fall off to the track The risk on the side brings hidden dangers to the safe operation of the tunnel, and also affects the normal storage of equipment in the tunnel
[0004] In the prior art, whether the working state of the tunnel protective door is abnormal is often found through the inspection and maintenance of the maintenance personnel. Although it can meet the needs of the normal use of the tunnel protective door to a certain extent, it often requires frequent inspections by the maintenance personnel to ensure The normal use of the tunnel protective door, which greatly increases the application cost of the tunnel protective door
At the same time, once the tunnel protective door suddenly fails or falls into the track area during the maintenance gap, it is difficult for the maintenance personnel to find out in time, and it is not easy to realize the accurate positioning of the abnormal tunnel protective door, and once the tunnel protective door falls to the track area, It is bound to cause potential safety hazards to the train traffic in the track area, easily lead to accidents, and thus adversely affect the safe operation of the tunnel

The invention discloses a dropping-off resisting device suitable for a tunnel protective door, and belongs to the relevant technical field of tunnel protective doors. Alarming assemblies composed of rollers, chains, traction motors, control modules and the like are arranged on a separating wall of one side of the back surface of the tunnel protective door; and the chains of the alarming assembliesare connected with the rollers and the back surface of the tunnel protective door correspondingly, the traction motors drive the rollers to rotate correspondingly, the controller modules can give analarm correspondingly when the tunnel protective door fails or drops off, the chains can pull the protective door from a tunnel track area, and safe motion and operation of the tunnel track area is ensured. According to the dropping-off resisting device suitable for the tunnel protective door, the structure is simple, the arrangement is simple and convenient, precise alarming when the tunnel protective door fails or drops off can be effectively realized, the tunnel protective door is prevented from dropping to the tunnel track area, rapid discovery and in-time overhaul when accidents occur tothe tunnel protective door are effectively realized, the safe motion and operation of the tunnel are ensured, the overhaul period is shortened, and the dropping-off resisting device has good application and prospect value.
Description
technical field [0001] The invention belongs to the related technical field of tunnel protective doors, and in particular relates to a fall prevention device suitable for tunnel protective doors. 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 passage and the train track area of the tunnel; in addition, communication, signal, power, etc. The storage door openings of the equipment are generally separated from the train track a...
