A safety warning device for highway bridge construction

Abstract

The invention discloses a safety warning device for road bridge construction, which relates to the technical field of road construction, and solves the problem that common warning signs are easily affected by the vibration of passing vehicles and are prone to unexpected situations. The general warning device does not have the function of auxiliary forced parking The problem. A safety warning device for highway bridge construction, comprising a base; the inner edges of the top on both sides of the base are fixed with side plates by bolts; the outer edges of the top on both sides of the base are fixed with guide rails by bolts, and the guide rails Two sets of sliders are slidably provided on the top; sliding vertical bars are provided in the middle of the guide rails through sliding blocks, and the tops of the sliding vertical bars are fixedly connected by connecting rods provided with bolts; idle wheels and side pulleys are provided for The warning device provides an auxiliary function of forced parking, and the rotation of the tires of the car can prevent the car from continuing to move through the idle wheel, and at the same time, it can stop the car with the shock absorption function of the concave frame.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a safety warning device for road bridge construction. Background technique [0002] With the development of national productivity, the country's construction of transportation facilities is gradually accelerating. In order to achieve the goal of modernization, the quality of roads and bridges is improving, and road repairs and bridge maintenance are being carried out all the time. In the process, it is necessary to use warning devices to notify pedestrians and vehicles. [0003] After retrieval, for example, the patent No. CN208328754U discloses a warning device for highway bridge construction, including a base, a support plate, a fixing plate, a mounting plate and an outer casing, a support plate is installed on one side of the top of the base, and the top of the base An outer sleeve is installed on the other side of the support plate, a battery box is installed on th...

Problems solved by technology

[0007] The purpose of the present invention is to provide a safety warning device for highway and bridge construction, to solve the problem that the currently used warning devices proposed in the above background technology mainly carry out early warning and interception of passing vehicles by setting obvious warning signs, and generally do not have the function of preventing accidents. , When maintaining a turning or inclined road section, the commonly used warning signs are easily affected by the vibration of passing vehicles and displaced. In many road sections, sudden braking may not be able to stop in time, and accidents are prone to occur. The general warning device does not have the problem of assisting forced parking.
