Flexible connection safety set for highway maintenance operation transition area

Abstract

The invention discloses a flexible connection safety set for a highway maintenance operation transition area; the set comprises a dragging support, two drawing rope channels are formed in the dragging support, a first drawing rope is arranged in one drawing rope channel, and a second drawing rope is arranged in the other drawing rope channel. The first drawing rope and the second drawing rope are respectively released through a rope releasing mechanism; a plurality of first reflective cones are arranged on the first drawing rope at intervals, a second reflective cone is arranged at the tail part of the second drawing rope, and a connecting rope is connected between the first reflective cone and the second reflective cone; and a triangular transition area is formed among the first drawing rope, the second drawing rope, the connecting rope and the dragging support. According to the invention, the triangular transition area is formed at the tail part of the mobile operation construction vehicle, and the driving state of passing vehicles is adjusted in time in the triangular transition area, so that traffic accidents caused by construction operation are avoided, and the occurrence rate of safety accidents of mobile operation of lanes occupied by expressways is reduced.

Description

technical field [0001] The invention relates to the technical field of expressway maintenance operations, in particular to a soft-connection safety cover set in the transition zone of expressway maintenance operations. Background technique [0002] When carrying out mobile maintenance work on a highway with dense traffic and high speed, the maintenance work needs to occupy the lane for a long time, and the moving speed is very slow. Some vehicles may not be able to change lanes in time and the braking distance is not enough, and there may be problems of rear-end collision or scratching of mobile sign vehicles and construction vehicle equipment, which will cause greater safety hazards to maintenance and construction operations, and personal accidents may easily occur. [0003] And at present, when performing highway maintenance operations, it is necessary to manually place signs or reflective cones to achieve the function of prompting and warning. However, after a section of...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a soft-connected safety cover set in the transition area of ​​expressway maintenance work, to solve the problem that rear-end collision or scratching of moving sign vehicles and construction vehicle equipment are easy to occur during expressway maintenance work, and the need for Manual placement of sign boards or reflective cones increases the labor intensity of operators, so as to avoid the phenomenon of rear-end collision or scratching of mobile signage vehicles and construction vehicle equipment, and automatically realizes the placement of manual placement of signboards or reflective cones, reducing Labor intensity
