A horizontal telescopic ultra-wide bridge inspection vehicle

Abstract

The invention mainly discloses a horizontal telescopic ultra-span bridge inspection vehicle. Its technical proposal includes a vehicle body, a turning platen, a connecting rod oil cylinder, connecting rods and a truss as a whole. The vehicle body is provided with a large turntable. The inside of the large turntable is provided with a slideway, and the telescopic arm and the telescopic oil cylinder are arranged in the slideway, and the telescopic oil cylinder pushes the telescopic arm to move left and right in the slideway so as to push the turning table to move left and right. There is a bracket, and a counterweight is provided on the bracket, and the counterweight includes a counterweight oil cylinder and a counterweight, and a safety device is provided on the turning table, and the safety device includes a reel, wound on the reel safety rope and binder. The invention can realize the horizontal expansion and contraction of the whole truss, increase the spanning width, expand the use range of the bridge inspection vehicle, change the position of the counterweight center, improve the use performance of the inspection vehicle, and improve the operation safety of the bridge inspection vehicle.

Description

technical field [0001] The invention relates to the technical field of bridge detection, in particular to a horizontally telescopic super-wide bridge detection vehicle. Background technique [0002] At present, the sidewalk of domestic highway bridges is more than 3 meters wide, and many bridges are laid with pipes and lighting fixtures. Therefore, during bridge inspection and maintenance, the actual bridge inspection vehicle span width needs to be 4 meters or more. The main truss part of a general bridge inspection vehicle is composed of the whole truss, the car body, the turning platform, the large turntable and the counterweight. The distance between the car body and the whole truss is fixed, that is, its span width is designed to be constant. Under the structure, when pipes and lighting fixtures are laid outside the bridge, the spanning distance of the truss as a whole is not enough to extend the truss as a whole to the outside of the bridge, and the inspection vehicle c...

Problems solved by technology

The main truss part of a general bridge inspection vehicle is composed of the whole truss, the car body, the turning platform, the large turntable and the counterweight. The distance between the car body and the whole truss is fixed, that is, its span width is designed to be constant. Under the structure, when pipes and lighting fixtures are laid outside the bridge, and the overall spanning distance of the truss is not enough to extend the truss to the outside of the bridge, the inspection vehicle can hardly meet the actual requirements, so that it cannot carry out the inspection work by the way

Moreover, the counterweight in the existing testing vehicle is fixed, and affected by the counterweight, the center of gravity of the vehicle cannot be adjusted, and the use is limited

In addition, as a platform for high-altitude operations, the bridge inspection vehicle has extremely high requirements for operational safety. The current safety measures on the bridge inspection vehicle are not perfect, resulting in many casualties of inspectors. Once the working arm breaks, the inspectors will not have Therefore, it is urgent to improve the operating safety of bridge inspection vehicles to ensure the personal safety of inspectors
