Rotatable windshield device for highway bridge

Abstract

The invention discloses a rotatable windshield device for highway bridges, which belongs to the technical field of traffic safety and solves the problem that the angle adjustment of the windshield in the existing device is inconvenient, and the windshield angle cannot be adjusted according to changes in seasons and weather. , which weakens the problem of windshield effect; its technical characteristics are: including a base, a support column and a windshield, the middle position of the upper surface of the base is fixed and welded with a support column, the upper part of the support column is sleeved with a bearing seat, and the bearing seat It is rotatably connected with the support column, and a torsion spring is installed at the bottom of the bearing seat; the outer surface of the bearing seat is fixedly connected with an external threaded sleeve with bolts, and the two side walls of the external threaded sleeve are fixed with welded windshields; the present invention can avoid The windshield breaks under the impact of strong cross winds, prolonging the service life of the windshield, and at the same time, it can enhance the gripping ability of the base when the wind speed is high, and enhance the stability of the base.

Description

technical field [0001] The invention relates to the technical field of traffic safety, in particular to a rotatable windshield device for highway bridges. Background technique [0002] When a car traveling at high speed is affected by the cross wind, it often induces a car accident; the cross wind has a greater impact on vans, large passenger cars, canvas vans and other box-shaped vehicles, because such vehicles have a higher overall center of gravity and a larger lateral area; Lightweight cars are also susceptible to crosswinds. In addition, the effect of crosswind is intensified with the increase of vehicle speed. The moment a car drives out of a tunnel, or when driving towards a bridge, high embankment, etc. that is penetrated by the wind, it will often be suddenly attacked by a strong cross wind. [0003] At present, at the bridge or tunnel exit, people install a windshield device to ensure the stability of the car during driving. Chinese patent CN207987795U discloses ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a rotatable windshield device for highway bridges, including a base, a supporting column and a windshield, the middle position of the upper surface of the base is fixed by welding the supporting column, and the upper part of the supporting column is sleeved with a bearing seat. The bearing seat is rotatably connected with the support column, and a torsion spring is installed at the bottom of the bearing seat, and the torsion spring is fixedly sleeved on the support column; the external surface of the bearing seat is fixedly connected with an external threaded sleeve, and the Welded windshields are fixed on both sides of the outer threaded sleeve to solve the problem that the angle adjustment of the windshield in the existing device is inconvenient, and the windshield angle cannot be adjusted according to seasons and weather changes, which weakens the windshield effect.
