Automatic retracting and releasing device and method for traffic cone isolation belt

Abstract

The invention discloses an automatic retracting and releasing device and method for a traffic cone isolation belt, and belongs to the technical field of traffic safety. The device comprises a plurality of groups of automatic folding and unfolding units arranged along the driving direction and a control center. Each group of automatic retracting and releasing unit comprises a multi-stage hydrauliccylinder and a laser radar. When the multi-stage hydraulic cylinder is in a contraction state, each stage of oil cylinder is provided with an extending section on which a traffic cone is fixed. The multi-stage hydraulic cylinder is obliquely arranged relative to the roadside line in a contraction state. The laser radar is arranged in the center of the top of the tunnel, detects road surface pointcloud data and transmits the information to the control center, and the control center judges whether a fault occurs or not according to the received road surface point cloud data and transmits a judgment result to the multi-stage hydraulic cylinder to control the multi-stage hydraulic cylinder to stretch out or draw back. Automatic releasing of the traffic cone isolation belt is achieved, and potential safety hazards caused by manual arrangement are avoided. The response time is short, the layout is timely, and secondary accidents can be effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of traffic safety, in particular to a device and method for automatically retracting and retracting a traffic cone isolation belt. Background technique [0002] The high-speed tunnel section is an accident-prone section. When an accident occurs, it is often necessary to isolate the lane to prevent secondary accidents caused by high-speed vehicles passing by failing to detect dangerous situations in time. In order to temporarily separate lanes, it is usually necessary to place a large number of traffic cones to separate lanes and guide vehicles to another lane by placing traffic cones over a long distance. [0003] The existing technology is to arrange traffic cones manually, which not only has the defects of low efficiency and high potential safety hazards, but also because it takes a certain amount of time for the staff on the high-speed road section to arrive and arrange the scene, resulting in the inabili...
