Description

Rail type hanging basket walking device for bridge inspection vehicle

Technical Field

The utility model relates to a running gear field. More specifically, the utility model relates to a rail mounted hanging flower basket running gear for bridge inspection car.

Background

At present, in some bridge engineering, the traditional hanging basket traveling system for the upper beam of the bridge body still adopts the mode that I-shaped steel is connected onto a frame through bolts, and a hanging basket lifting system achieves the purpose of checking all parts of the upper beam by moving along the direction of a guide rail and lifting the hanging basket in a mode that rollers of a steel structure are placed on I-shaped steel guide rails. The conventional method has several disadvantages:

1) the roller wheels are placed on the I-shaped steel guide rails, the deviation of the roller wheels in the direction vertical to the guide rails can be limited through the wheel rims, but the tipping of the hanging basket system cannot be limited, and as the working environment of most bridge inspection vehicles is in a strong wind environment, a set of tipping prevention device must be added to the hanging basket lifting system.

2) The I-steel guide rail, the anti-tipping device and the roller are all made of steel structures, so that the weight of the whole hanging basket traveling system is increased, and the weight of a frame is also increased. The heavy inspection vehicle can improve energy consumption no matter adopting manual transmission or motor transmission undoubtedly.
