Bridge passage restriction device

Abstract

The invention discloses a bridge passage restriction device. The bridge passage restriction device comprises a bridge deck; a middle column is built at the middle part of the bridge deck; edge columnsare built on the two sides of the bridge deck; arc edge plates are arranged on the external side surfaces of the edge columns; circular mounting cavities are formed between the edge plates and the edge columns; driving motors are mounted in the mounting cavities; reels sleeve output shafts of the driving motors; rotating pins are arranged at the top ends of the edge columns; supporting beams arepinned at the top ends of the edge columns through the rotating pins; connecting rods are welded at one ends, far away from the middle column, of the supporting beams; binding holes are formed in oneends, far away from the supporting beams, of the connecting rods; and a steel wire rope is bound on the binding holes. The bridge passage restriction device has the advantages that width restriction and height restriction effects can be simultaneously realized, the adjusting and mounting are more convenient, the passing of overhauling vehicles is made convenient, traffic congestion is reduced, andportal structures formed among the edge columns, the supporting beams and vertical columns are convenient for the passing of non-motor vehicles.

Description

technical field [0001] The invention relates to the technical field of bridge installations, in particular to a bridge traffic restriction device. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the bridge abutment; the auxiliary structures refer to the bridge head board, conical slope protection, ba...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a bridge traffic limiting device, which solves the problem that most of the current width limiting and height limiting devices are fixed installations, and when the maintenance vehicle needs to enter the bridge to consign the faulty vehicle or repair the bridge It cannot be stowed away in special circumstances, which may easily cause traffic jams
