Intelligent external inspection and maintenance vehicle for rail beam of suspension monorail transit

Abstract

An intelligent external inspection and maintenance vehicle for a rail beam of suspension monorail transit aims to achieve the automatization, informatization and intellectualization of the external fault and defect inspection of the rail beam and provide working conditions for inspection and maintenance. The intelligent external inspection and maintenance vehicle comprises a vehicle body, a driving unit, an intelligent detection unit, a vehicle-driving control unit and a safety protection unit, wherein the driving unit consists of a power battery and suspension bogies; a suspension monorail beam inspection and maintenance platform is arranged at the rear part of the vehicle body; the vehicle body is equipped with sensor lifting and lowering supports, contour detectors, a lifting and lowering fence translational track, an inspection and maintenance work lifting and lowering platform, gauge detection laser sensors and corrosion detection cameras; the suspension monorail beam inspection and maintenance platform can move horizontally and vertically on the lifting and lowering fence translational track; the motion range of the suspension monorail beam inspection and maintenance platformcovers the left, right and lower sides of the rail beam for providing an inspection and maintenance platform capable of moving horizontally and vertically at the external of the rail beam; the contour detectors and the corrosion detection cameras of an intelligent detection system are mounted at the sensor lifting and lowering supports which is capable of moving vertically on both sides of the middle part of the vehicle body; the corrosion detection cameras are mounted at the outer side of the middle of the sensor lifting and lowering supports; and the contour detectors are mounted at the inner side of the middle and top of the sensor lifting and lowering supports.

Description

Technical field [0001] The invention relates to a suspended monorail transportation track, in particular to a suspension monorail transportation track beam external intelligent inspection and maintenance vehicle. Background technique [0002] The suspended monorail transportation system is a new type of transportation system with low investment, simple construction, short construction period, energy saving and environmental protection. So far, only Japan and Germany have actual operating lines, and there are no domestic operating lines. Different from the traditional urban rail transit system, the suspended monorail transit track beam is generally constructed overhead (generally about 11m above the ground), and the train is suspended below the track beam and the height above the ground is not less than 5m. Therefore, there are no inspection and maintenance equipment transportation conditions and work platforms inside and outside the track beam, and it is difficult for the staff t...

AI Technical Summary

Problems solved by technology

Due to the long-term exposure of the steel track beam to the natural environment, on the existing test line, there are often problems such as cracks, corrosion, loose bolts and poor sealing of the track beam joints on the outside of the track beam. It is necessary to use professional tools to clean the track Beams for manual maintenance
