Abstract

The present invention provides a road and bridge security height limiting device, which includes a first security mechanism, a second security mechanism, a first detection switch and a controller, and the second security mechanism and the first security mechanism are distributed forward and backward along the driving direction of the vehicle. The first security mechanism includes a first security bracket and a first deceleration mechanism, the first deceleration mechanism includes a pressure applying frame and a pressure applying mechanism, the second security mechanism includes a lifting mechanism, a moving deceleration pile and a clamping positioning mechanism, and the lifting mechanism includes a lifting plate And two groups of hoisting mechanisms, two groups of hoisting mechanisms all include fixed columns, drive motors, winches and wire ropes, and the mobile deceleration piles include triangular pile bodies, first buffer springs and buffer plates. The height limiting device not only has the function of height limiting, but also can effectively realize the deceleration of the vehicle once the vehicle collides with the height limiting device, and can realize the protection of the vehicle to the greatest extent, thereby avoiding serious consequences happened.

Description

technical field

[0001] The invention relates to a safety height limiting device for roads and bridges. Background technique

[0002] Elevation-limiting viaduct is a portal frame structure used at the entrance of bridges and tunnels to protect bridges and tunnels and prevent super-high vehicles from hitting bridges and tunnels and causing damage to bridges and tunnels; in addition, vehicles hitting bridges and tunnels It will also cause personal and property damage to the vehicle and driver. Most of the height limiters in the prior art are connected in the form of welding, that is, the height limiters are fixedly connected at the entrances of bridges and tunnels. In this way, once a large truck collides with the height limiter, it will cause serious damage to the vehicle. Injuring the vehicle driver and passengers will bring more serious consequences.
