Road limit elevated

Abstract

The invention discloses a road height limiting frame. The road height limiting frame comprises a first column 2 and a framework 3, a cross beam 1 is arranged between the first column 2 and the framework 3, one end of the cross beam 1 is rotatably connected with the first column 2, and the other end of the cross beam 1 is slidably connected to the framework 3; a swing plate 5 is rotatably connectedto a road through a first hinging point 4 and is located between the first column 2 and the framework 3, a first arc rack 6 with the first hinging point 4 being the center of the circle is arranged on the lower surface of the swing plate 5, and the swing plate 5 is provided with a balancing weight 7. The road height limiting frame has an obvious effect on vehicle speed reducing and can be repeatedly utilized.

Description

technical field [0001] The invention relates to a traffic facility device, in particular to a road height limiter. 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. Therefore, the basic requirements for the height limiter are: first, to ensure that super-high vehicles will not hit bridges and tunnels, and prevent vehicles from destroying bridges and tunnels; 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. Once a large truck collides with the height limiter, the large truck will deform the height limiter, resultin...

Problems solved by technology

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. Once a large truck collides with the height limiter, the large truck will deform the height limiter, resulting in Repair personnel need to replace a new height-limiting frame, that is, the height-limiting frame in the prior art cannot be reused, and the damage rate is high; the main reason for the high damage rate of the height-limiting frame is the deceleration effect of the height-limiting frame in the prior art on the vehicle Not obvious, that is, the height limiter in the prior art cannot effectively prevent the vehicle from stopping
