Municipal device for vehicles in specific width range to pass

Abstract

The invention belongs to the technical field of width limiting devices and particularly relates to a municipal device for vehicles in a specific width range to pass. The device comprises a fixed shell, a trigger mechanism and the like. A width limiting device in the device is provided with the trigger mechanism, a movement strip identifying vehicle speed is arranged in the mechanism, rapid advancing vehicles make the movement strip in the trigger mechanism swing around a hinge point at a certain angle, so that a rack connected with the movement strip and a gear in the trigger mechanism executeengagement work, two width limiting column mechanisms are in thin and high shapes from initial short and thick shapes, the distance between the two width limiting column mechanisms becomes wide frominitial narrow, and the rapid advancing vehicles safely pass through. Slowly advancing vehicles make a trigger block in the trigger mechanism swing at a certain angle, so that a rack connected with the trigger block is not engaged with the gear in the trigger mechanism, the trigger mechanism does not work, an energy storage mechanism does not work, the two width limiting column mechanisms are maintained in the short and thick shapes, and the purpose of making vehicles in a specific width range pass through is achieved.

Description

technical field [0001] The invention belongs to the technical field of width limiting devices, in particular to a device for passing vehicles within a specific width range used in municipal engineering. Background technique [0002] At present, the existing width-limiting devices mostly use cemented pier or plastic buckets to fill water, set a certain width and place it on the road, and when the vehicle passes by, it will limit the width of the passing vehicle; but when the driver is in the When driving at night, the warning strip on the width-limiting pier will lose its warning effect if it is exposed to the sun for a long time, so that the car will easily hit the width-limiting pier, and the speed will quickly hit the width-limiting pier set on the road. , will cause great bodily harm to the driver and passengers in the car; at the same time, even if the warning strip has a warning effect, the driver will feel tired after driving for a long time or the driver is distracted...

AI Technical Summary

Problems solved by technology

[0005] The problem to be solved by the present invention is to provide a device for passing vehicles within a specific width range used in municipal engineering, so as to overcome the problem that the width of the width limiting device in the prior art will limit the width of the vehicle when it is fast or slow. If a fast-moving vehicle hits the width limiting device, it will receive a great impact, which will cause great personal injury to the driver and passengers in the vehicle
