Description

A bridge height limiting device

technical field

The utility model relates to the technical field of bridge height limitation, in particular to a bridge height limitation device.

Background technique

A bridge refers to a building built for roads to cross natural or artificial obstacles. It is erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. A bridge generally consists of a superstructure, a substructure and ancillary structures. The superstructure mainly refers to the bridge span structure and support system; the substructure includes abutments, piers and foundations; , diversion engineering, etc.

Bridge height limit is the main measure to restrict large vehicles from passing through important bridge sections. Every year, important bridges are crushed due to unrestricted large vehicles, and then a lot of money is spent on maintaining bridges, which affects traffic.

And, at the entrances and exits of roads, bridges and tunnels where the height of vehicles needs to be limited, it is often necessary to set up vehicle height limit bars. Most of these vehicle height limit bars are designed and manufactured to limit specific heights, which can effectively improve the efficiency and quality of vehicle circulation. Avoid traffic accidents.

With the rapid development of the transportation industry, bridges across rivers and rivers have been erected one after another, shortening the distance between the rivers, lakes and seas, and greatly facilitating the communication and mutual assistance between the two sides; however, the limitations of existing bridges The height of the high pole is relatively fixed. While restricting the passage of super high vehicles, it also hinders special vehicles, such as fire trucks and sprinklers. Remove the height limit pole. At the same time, the height limit pole of the bridge is often touched and hit by the protrusions on the top of the vehicle. There is no guiding sliding structure on the surface of the height limit pole. .

Therefore, we need a bridge height-limiting device to solve the problem that the height-limiting rod cannot be quickly adjusted in height and disassembled, and the problem that it collides with the protrusion on the top of the vehicle and causes it to fall and injure pedestrians and vehicles.

For example, the existing patent notification number CN112081031A provides a bridge height limiting device, which adopts a buffer structure. Make the driver aware of the height limit pole, so as to stop driving and avoid collision with the fixed height limit pole to cause personal injury. When the vehicle leaves the moving pole, the pushing block moves to the bottom of the inclined slide rail under the action of weight, thereby driving the moving pole to move forward. Resetting is convenient for early warning of the next super-high vehicle; by setting a movable pole in front of the height-limiting pole, it can remind the driver of the unconscious super-high vehicle to reduce the occurrence of accidents, and through the buffer structure It can be cushioned when the moving rod is reset to avoid damage to the equipment caused by impact.

However, its device is only suitable for reminding the driver of an unconscious super-high vehicle to reduce the occurrence of accidents, and the buffer structure can be used for buffering when the moving rod is reset, so as to avoid damage to the equipment due to impact, and cannot prevent the height limit rod from being damaged. Collision with the protrusions on the top of the vehicle will cause it to fall and injure pedestrians and vehicles.

The existing bridge height limiting device cannot adjust the height of the height limiting rod according to actual use requirements, and it is inconvenient to quickly disassemble the height limiting rod. At the same time, the bridge height limiting rod is often touched and hit by the protrusions on the top of the vehicle. There is no guiding sliding structure on the surface, which may easily cause the height limit pole to fall and injure passers-by and vehicles, causing losses.
