Adjustable guardrail structure for bridge

Abstract

The invention relates to the field of guardrails, and especially relates to an adjustable guardrail structure for a bridge. The guardrail structure comprises guardrails vertically arranged on two sides of the bridge, each guardrail comprises stand columns located at the two ends of the guardrail, a limiting rod extending to the position below the liquid level is arranged at the bottom of each stand column located on the upstream, an obstacle sensing system is arranged between the two limiting rods, an upper cross beam fixedly connected to the upper ends of the two stand columns and a handrailassembly located below the upper cross beam are arranged between the two stand columns located on the downstream, each stand column is of a hollow structure, a vertical stud is rotatably sleeved witheach stand column and extends downwards to the position below the liquid level, the two sides of the handrail assembly are connected to the vertical studs in a screwed mode, a driving device for driving each vertical stud to rotate is arranged at the end part of the vertical stud, and the obstacle sensing system is electrically connected with the driving devices and used for controlling the guardrail assembly to ascend and descend movably. The guardrails can be automatically adjusted to descend according to the liquid level condition so as to intercept large garbage or waterweeds, and the problems that an original fixed guardrail is single in structure and few in function are solved.

Description

technical field [0001] The invention relates to the field of guardrails, in particular to an adjustable guardrail structure for bridges. Background technique [0002] There are often guardrails on both sides of the road surface of bridges for isolation and protection. Most of the bridges built on rivers or ponds in some scenic spots are set near the water and are relatively narrow, and the guardrails on them are all fixed and non-adjustable structures. The guardrail has a single structure and few functions, and the large flow of people in the scenic area is likely to cause garbage pollution to rivers or pools and lakes. Because the liquid surface around the bridge is easy to touch, it is more convenient to clean up. In view of this, we propose an adjustable guardrail for bridges. The structure is convenient for intercepting large garbage or aquatic plants on the liquid surface, so as to purify the water flow to a certain extent. Contents of the invention [0003] The pur...
