Flexible height limiting mechanism capable of automatically rebounding and resetting

Abstract

The invention belongs to the field of height limiting devices, and particularly relates to a flexible height limiting mechanism capable of automatically rebounding and resetting, which comprises two sets of supporting columns, flange plates are fixedly welded to the bottoms of the two sets of supporting columns, and the flange plates are fixed to the ground through bolts. According to the flexible height limiting mechanism, the cross rod can rotate through disconnected equipment, so that when a vehicle impacts on the cross rod excessively, the cross rod can rotate, the vehicle cannot be subjected to large impact, the conditions of large damage and personnel injury are avoided, the cross rod can automatically reset after the vehicle passes through under the action of a spring. Meanwhile, when the disconnected cross rod is rushed open, the infrared transmitter and the infrared receiver are disconnected, so that an alarm is triggered, the loudspeaker sends out an alarm sound for warning, meanwhile, the camera can collect vehicle information and store data, and an over-high vehicle can be conveniently found to be responsibilities.

Description

technical field [0001] The invention relates to the technical field of height limiting devices, in particular to an automatic rebound reset flexible height limiting mechanism. Background technique [0002] There are roughly two types of height-limiting racks: fixed height-limiting racks and adjustable height-limiting racks. The fixed integrated height-limiting racks are one-time non-adjustable height-limiting racks that intercept vehicles by the rack itself. Passage must be lifted by external forces, such as cranes, etc. The fixed one-piece elevation limit is mainly used for the portal frame at the entrance of bridges, culverts, and tunnels. It is generally welded by steel structures and plays the role of protecting bridges, culverts, and tunnels; The signboard, marked with the number of limited height meters, is used to remind the vehicle. The adjustable height limit frame is divided into two types: manual height limit frame and electric height limit frame; the manual heigh...

Problems solved by technology

[0003] Most of the existing height-limiting mechanisms are fixed pillars supporting the cross-bar to limit the height, but some drivers will drive the vehicle against the height-limiting cross-bar without paying attention, and the vehicle has a certain impact force, thus Acting on the surface of the crossbar, the crossbar will scratch the vehicle, and at the same time, it is easy to cause harm to the people inside the vehicle, and it does not have the function of cushioning
