Abstract

The invention discloses an anti-collision self-resetting boundary frame for a bridge overpassing highway and railway, which comprises two bases, wherein upper ends of the two bases are respectively provided with a first guiding slot, and the first guiding slot is provided with a first guiding rod; two ends of the first guiding rod are respectively fixedly connected to opposite inner walls of the first guiding slot; a supporting column sleeves the first guiding rod; the supporting column is slidably connected with the first guiding rod; a first spring sleeves a part of the first guiding rod positioned between the supporting column and the inner wall of the first guiding slot; the supporting column is provided with a lifting device; the upper end of the lifting device is fixedly connected with a sliding block; a movable plate is disposed above the sliding block; a lower end of the movable plate is provided with a sliding slot matched with the sliding block; the sliding slot is provided with a second guiding rod; and the second guiding rod penetrates the sliding block and is fixedly connected to the inner wall of the sliding slot. The anti-collision self-resetting boundary frame for the bridge overpassing the highway and railway has the advantages of being simple in structure and strong in stopping an ultra-high car, so that traffic safety of the railway is better guaranteed.

Description

technical field [0001] The invention relates to the technical field of road limit elevated, in particular to an anti-collision self-resetting limit frame for overspan highway and railway bridges. Background technique [0002] The boundary frame is a structure that is set above the road to limit the height of passing vehicles in order to protect structures such as bridges and culverts in front. If the vehicle exceeds the allowable height of the bridge and culvert, all passing is prohibited. Most of the bridge protective frames currently in use are rigid structures, welded with section steel or steel pipes, and the boundary frame structure is very rigid. When a large vehicle exceeds the height of the boundary frame and collides with the boundary protection frame, effective deformation cannot occur. The huge impact force generated in an instant destroys the protective frame. If the limit frame structure is knocked down, it will cause a safety accident and threaten the safety o...
