Road traffic control device for highway bridge

Abstract

The invention provides a road traffic control device for a highway bridge, relates to the field of road traffic control, and solves the problems that only a shielding function can be realized, and other functions cannot be realized in the lifting process of a shielding fence. Although a damping device is arranged, the damping structure is single, the effect is poor, flow guiding after vehicle collision cannot be achieved, and damage to a main body part cannot be better relieved; and effective cooperation with the deceleration strip cannot be achieved, and overload alarm and automatic opening of the blocking fence are achieved. The road traffic control device for a highway bridge comprises a base structure, a first elastic deceleration strip and a second elastic deceleration strip. And a main body rod is connected to the base structure in a sliding manner. Due to the fact that the sponge block is attached to the connecting base and makes contact with the right end face of the main bodyrod, when the electric telescopic rod pushes the shielding fence to move upwards, the air suction opening formed in the net opening is in a wiping state under the action of the sponge block, and wiping of the air suction opening can be achieved when the shielding fence is opened.

Description

technical field [0001] The invention belongs to the technical field of road restriction, and more specifically relates to a road restriction device for highway bridges. Background technique [0002] The height limit device is to limit the height of the passing cars. It is generally installed at the entrance of the tunnel, the entrance of the bridge hole, etc., to prevent the over-high cars from entering, and to prevent the top of these cars from colliding with the top of the tunnel, the top of the bridge hole and other facilities. to the protective effect. [0003] For example, the application number: CN201811182372.5, the present invention provides a road traffic control device for highway bridges, including: buffer springs, rubber buffer blocks, traffic control rods, solar panels, weighing boards and geared motors; The inner side of the cover is provided with a deceleration motor, and the rotating shaft passes through the bearing upwards and is inserted into the bearing t...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a road restriction device for highway bridges to solve the existing problem that the shielding fence on the existing device can only realize the shielding function, and cannot be used in the lifting process of the shielding fence. In addition, the practicability is low; moreover, although the existing device is equipped with a shock absorber, on the one hand, the shock absorbing structure is single, and the effect is relatively poor; flow, can not better achieve the slowdown of the damage to the main part; finally, the existing device can not effectively cooperate with the speed bump to realize the overload alarm and automatically open the barrier
