A bridge detection device

Abstract

The invention provides a bridge detection device. A driving car and a driven car are connected with connection frames respectively; the bottom ends of the connection frames are fixedly connected with butt joint driving heads; each butt joint driving head is internally provided with a movable arm which can move transversely at the bottom of a bridge under the driving of the butt joint driving head; in opposite end parts of the two movable arms which are opposite to each other in the transverse direction, one end part is provided with a male head and the other opposite end part is provided with a female head; the two movable arms which are opposite to each other in the transverse direction are in butt joint and released by matching the male head with the female head respectively under the driving of the butt joint driving heads, and a pair of transverse guide rails are formed by the two movable arms which are opposite to each other in the transverse direction; and the transverse guide rails are provided with driving wheels at the two ends of a working walking platform respectively, and the working walking platform moves transversely on the transverse guide rails. When the device provided by the invention is used for overhauling the bridge, a working platform and a retractable arm are at a simply supported beam mechanical state, so that the safety of workers is effectively guaranteed and the device can automatically keep away from obstacles including piers and the like; and the device does not occupy a traffic lane, can work flexibly and conveniently, and has high construction efficiency and low production cost.

Description

technical field [0001] The invention belongs to the field of bridges and relates to bridge detection, in particular to a bridge detection device. Background technique [0002] Regular inspection of bridges is a condition for assessing the health status of bridges, understanding and controlling the occurrence and development of bridge diseases, formulating reasonable maintenance plans, prolonging the service life of bridges and ensuring the safety of bridges in service. The impact of bridge inspection vehicles on the safety of bridge inspection personnel, project cycle and traffic plays a decisive role. [0003] At present, the commonly used bridge inspection vehicles such as folding arm type, hanging basket type, and truss type are all in a cantilever state during work, and the stress conditions are harsh. In order to ensure the safety of inspectors, the structural size of the working device is often relatively large. At the same time, in order to prevent the rollover probl...
