Work car for main cables of suspension bridge

Abstract

The invention relates to bridge maintenance equipment, in particular to a work car for main cables of a suspension bridge, which is used for maintaining the main cables of the suspension bridge. The work car for the main cables of the suspension bridge comprises a frame, wherein multiple walking wheels are arranged side by side on the bottom of the frame at intervals along the longitudinal direction; the frame is located on the main cables through the walking wheels and further can move along the main cables; the front part of the frame is provided with a hoisting device which provides power for walking; a basket connected with the frame by a hinging way is suspended on the frame; each walking wheel is installed on a lifting seat which can be lifted; and each lifting seat is driven to lift by a power device which is installed on the frame alone. During the walking process of the work car, when the walking wheels are lifted one by one, the frame can be caused to cross over attachment barriers on the main cables; in such a way, the construction difficulty is decreased and the maintenance efficiency is improved; in addition, the frame can be kept without inclination during the walking and maintenance processes through side roller wheels located on two sides of the frame and a correction device; and therefore, the maintenance is facilitated and the safety is improved.

Description

technical field [0001] The invention relates to bridge overhaul equipment, in particular to a suspension bridge main cable working vehicle used for overhauling the main cable of the suspension bridge. Background technique [0002] Suspension bridge is one of the main forms of super-long-span bridges. Compared with other structural bridges, suspension bridges can use less materials to complete relatively large spans, and the bridge deck is relatively higher. Temporary piers need to be built, which can be built on the surface of turbulent water, so it has become one of the preferred structures for modern bridge construction. [0003] The main cable is the main load-bearing component of the suspension bridge, and is generally made of high tensile strength steel (steel wire, steel strand, steel cable, etc.). The anti-corrosion maintenance of components is very important. The height difference of the main cable from the main tower of the bridge to the bridge deck is generally mo...

Problems solved by technology

[0003] The main cable is the main load-bearing component of the suspension bridge, and is generally made of high tensile strength steel (steel wire, steel strand, steel cable, etc.). The anti-corrosion maintenance of components is very important. The height difference of the main cable from the main tower of the bridge to the bridge deck is generally more than 100 meters.

At present, a working vehicle that can travel along the main cable is usually used for auxiliary maintenance work, but the existing main cable working vehicle is limited by its structure, and it is difficult to safely avoid the cable clips, intake and exhaust hoods, temperature and humidity sensors and other accessories on the main cable. objects, which increases the difficulty of maintenance; in addition, it is difficult to correct the deviation of the center of gravity caused by the external force during the operation of the work vehicle, which brings inconvenience to the operation and affects the safety.
