An adjustable height-limiting shelf on the road

Abstract

The invention discloses an adjustable height limiting rack on a road. The adjustable height limiting rack on the road comprises a road body; supporting columns are arranged on the two sides of the road body; a height limiting intercepting mechanism is arranged on the road body; slide grooves, intercepting plates, stopping blocks, sliding blocks, sliding mechanisms, fixing shafts and a height limiting rack are arranged on the height limiting intercepting mechanism; a lifting mechanism is arranged on the supporting columns; the lifting mechanism uses a transverse connecting plate, a stepping motor, a shaft coupling, fixed platforms, through holes, fixing bearings, a rotating shaft, take-up wheels, take-up grooves, wire outlet holes, lifting ropes and a protective housing; predication mechanisms are arranged in the supporting columns; the predication mechanisms use small grooves, infrared distancers, transparent protective glasses, LED display screens and height limiting information; an auxiliary mechanism is arranged on the external side of the transverse connecting plate; a controller is arranged on one side of the upper surface of the transverse connecting plate; and a remote controller is connected outside the controller. The adjustable height limiting rack on the road has the advantages of simple structure and strong practicability.

Description

technical field [0001] The invention relates to the field of road facilities, in particular to an adjustable height-limiting shelf on the road. Background technique [0002] At present, the common height limiters on the road generally use metal frames to limit the height of the vehicle, and they can be adjusted. Sometimes the driver does not notice the limited height limit ahead during driving, and drives the car directly past and collides. When the speed exceeds Fast times often cause loss of life and property, not only the driver will suffer greater injuries, but also cause harm to other people, there is a greater potential safety hazard, and after a collision, the overhead limiter will also be damaged to a certain extent, it is necessary to Carrying out repairs as a whole wastes manpower and material resources and increases road safety costs. Contents of the invention [0003] The purpose of the present invention is in order to solve the above-mentioned problem, has de...
