Horizontally telescopic type super-span bridge detection vehicle

Abstract

The invention mainly discloses a horizontally telescopic type super-span bridge detection vehicle. According to the technical scheme, the horizontally telescopic type super-span bridge detection vehicle comprises a vehicle body, an overturning platform plate, a connecting rod oil cylinder, a connecting rod and an overall truss; a big rotating table is arranged on the vehicle body, a slideway is arranged in the big rotating table, a telescopic arm and a telescopic oil cylinder are arranged in the slideway, the telescopic oil cylinder pushes the telescopic arm to move left and right in the slideway, and therefore the overturning platform plate is pushed to move left and right; the big rotating table is further provided with a support, a counterweight device is arranged on the support and comprises a counterweight oil cylinder and a counterweight part, and a safety device is arranged on the overturning platform plate and comprises a reel, a safety rope wound on the reel and a binder. The horizontally telescopic type super-span bridge detection vehicle can achieve horizontal telescoping of the overall truss, increase the span, widen the application range of the bridge detection vehicle, change the centre-of-gravity position of a counterweight, improve the use performance of the detection vehicle and improve the operational safety of the bridge detection 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
