A width limiting device for small road section construction used in traffic engineering

Abstract

The invention provides a width-limiting device for construction of small road sections used in traffic engineering, which includes rollers, shock absorbers, square pipe sleeves, guide wheels and tight release rods; the peripheral outer wall of the semicircular water tank is arranged in a circular array There are four rectangular slots, where two quarters of the height of the four rectangular slots are supported and welded with a positioning plate with a central jack, and each of the four rectangular slots is slidably inserted with a roller support shaft; The upper support sleeve of the lower half of the support tube has two guide wheels arranged at intervals up and down; there is a positioning disc on the outer opening of the tube hole, which is screw-locked, and the position of the positioning disc and the center of the plug is equal. An I-shaped notch is provided; an I-shaped elastic block is provided at the tail end of the tight unloading lever. The setting of the guide wheel of the present invention can prevent the rubber tire on the guide wheel from being damaged when the vehicle accidentally touches the guide wheel. The exterior paint of the vehicle is scratched.

Description

technical field [0001] The invention belongs to the technical fields of engineering width limiting and road facilities, and more specifically relates to a width limiting device for small road section construction used in traffic engineering. Background technique [0002] During the construction of traffic engineering, part of the road needs to be occupied. After the occupation, the width of the remaining road is limited. When there are many vehicles entering at the same time, it is easy to cause road congestion and traffic accidents. Therefore, it is necessary to set up a width limiting device on the construction road section , through the width limiting device, only one vehicle can pass through at a time, reducing the flow entering at the same time, avoiding congestion, and reducing the occurrence of accidents. [0003] Combining with the prior art, the inventors of the present invention found that although the existing engineering width-limiting device can be used routinel...
