A cantilever bridge maintenance platform

Abstract

The invention belongs to the technical field of bridge detection and repair, and particularly relates to a cantilever type bridge repair and maintaining platform; the cantilever type bridge repair and maintaining platform includes a flaw detection device and a walking mechanism; the walking mechanism can move by using a steel pipe at the top part of a bridge cement guardrail as a track, and the flaw detection device is installed on the walking mechanism, and the flaw detection device is suspended at outside of the cement guardrail; a probe of the flaw detection device is just faced to the outer wall of the cement guardrail. By using the steel pipe at the top part of a bridge cement guardrail as the track, the flaw detection device can move along the guardrail automatically, thus the flaw detection device is not transported manually, and the normal traffic of road is not influenced.

Description

technical field [0001] The invention belongs to the technical field of bridge detection and maintenance, and in particular relates to a cantilever bridge maintenance platform. Background technique [0002] Vehicles sometimes collide with guardrails on viaducts and expressway bridges. Under normal circumstances, cracks on the inner side of the guardrail are easier to penetrate, and workers can see them during inspections, while cracks on the outer side are not easily found. In the prior art, when detecting these cracks, it is necessary to use a vehicle to transport the entire set of flaw detection equipment to the location where the impact occurred on the bridge for detection. This detection method will occupy the inner lane and cannot be carried out without closing the bridge deck. Inspection and repair. On the one hand, this detection method wastes manpower and material resources, and the efficiency of vehicle inspection is revealed. On the other hand, it will seriously af...

Problems solved by technology

In the prior art, when detecting these cracks, it is necessary to use a vehicle to transport the entire set of flaw detection equipment to the location where the impact occurred on the bridge for detection. This detection method will occupy the inner lane and cannot be carried out without closing the bridge deck. Inspection and Repair

On the one hand, this detection method wastes manpower and material resources, and the efficiency of vehicle inspection is revealed. On the other hand, it will seriously affect the normal traffic of the road and increase the traffic burden.
