An inspection vehicle for bridges with main cables and suspension cables

Abstract

The invention discloses a detecting vehicle for a main cable and suspension cable structure bridge, belongs to the field of bridge overhaul devices, and particularly relates to a cable bridge detecting vehicle. The detecting vehicle comprises a main beam, a leveling mechanism, an overhaul platform, clamping mechanisms capable of rising and falling, walking driving mechanisms and a control system. Two of the clamping mechanisms capable of rising and falling are fixedly connected with the front end and the rear end of the main beam respectively, and the other two clamping mechanisms in the middle are arranged between the clamping mechanisms at the front end and the rear end through the walking driving mechanisms and matched and connected with the main beam in a driving mode through the walking driving mechanisms. By controlling the clamping mechanisms at the front end and the rear end and the clamping mechanisms in the middle to clamp, release and lift a cable and controlling the walking driving mechanisms to correspondingly drive the relative movement between the clamping mechanisms in the middle and the main beam, the purpose that the main beam of the detecting vehicle walks along the bridge cable and walks over joint barriers of the cable through the clamping mechanisms is innovatively achieved, and the safe and stable working environment is provided for maintainers.

Description

technical field [0001] The invention relates to an inspection vehicle for bridges with a main cable plus suspension cable structure, belongs to the field of bridge maintenance equipment, and in particular relates to a cable bridge inspection vehicle. Background technique [0002] The bridge inspection vehicle is a special vehicle equipped with bridge inspection instruments and used for mobile inspection and maintenance operations. The inspection vehicle can safely and quickly bring inspectors into the working position and provide a movable operating platform for mobile inspection or maintenance. Operation. And the staff will not affect the traffic on the bridge deck when checking the work of the car. The main working objects of the inspection vehicle for cable bridges are main cables, saddles, suspension cables, pillars, etc. At present, the general cable maintenance equipment adopts a wheel structure in its running mode. The symmetrically arranged rolling wheels surroundi...

AI Technical Summary

Problems solved by technology

At present, the general cable maintenance equipment adopts a wheel structure in its running mode. The symmetrically arranged rolling wheels surrounding the cable are pushed back to squeeze the cable to form a frictional force that can support the weight of the entire system. At the same time, the pressed rolling wheel is driven by a motor. Rolling and climbing along the cable, because its rolling wheels surround the cable in the cross section, this kind of equipment can only walk on the cable without auxiliary structure. For the cable bridge with main cable and suspension cable structure, this equipment cannot cross the main bridge Cable and suspension cable nodes cannot walk normally on the main cable
