Problems solved by technology

[0004] The first type is the rubber wheel clip rail type walking device, which mainly relies on the friction force between the rubber wheel and the guide rail to realize the driving, and the driving force provided is far from enough, and it is impossible to walk on the arch bridge with a large curvature, resulting in its Very narrow range of applications
[0005] The second is the hydraulic walking device, which uses the telescopic movement of the hydraulic cylinder to make the walking device walk. This method obviously requires a complex hydraulic mechanism to provide power for operation, thereby increasing the weight of the entire device and causing the walking process Becomes slow and unstable, greatly reducing the detection efficiency of arch bridges
[0006] The third type is the gear-type walking device, which adopts the transmission mode of gear and rack meshing. This kind of device requires high assembly requirements, increases costs, and is prone to jumping teeth, causing safety accidents

Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing.

[0025] figure 1 A running gear 10 for an arch bridge according to the invention is schematically shown. The running device 10 includes a guide rail 2 fixedly arranged on the bottom surface of the arch bridge. Guide rail 2 extends along the arc direction of the arch bridge (see Figure 4 ). Guide rail 2 can be selected as I-beam or channel steel, but the present embodiment is selected as I-beam. The top surface of the I-beam is fixed on the bottom surface of the arch bridge, the bottom surface is used for fixing the chain 31, and the side has two grooves. The guide rail 2 can be fixed to the arch bridge with bolts pre-embedded in the arch bridge, so as to ensure the firmness and reliability of the connection between the two. Of course, other fixing methods can also be selected between the guide rail 2 and the arch bridge.

Abstract

The invention relates to a travelling device for an arch bridge. The travelling device comprises a guide rail and a moving unit. The guide rail is fixedly arranged on the bottom surface of the arch bridge. A chain is fixedly arranged at the bottom end of the guide rail. The moving unit is suspended on the guide rail through suspension mechanisms. Chain wheels and power sources are arranged on the moving unit. The power sources can drive the chain wheels to rotate on the chain, and the moving unit is enabled to move on the guide rail. The travelling device is simple in structure, convenient to produce, stable and reliable in operation and convenient to operate, popularize and apply.

Description

technical field [0001] The invention relates to a running device for an arch bridge. Background technique [0002] As we all know, the safety of arch bridges is always the key concern of construction personnel, supervisors and post-maintenance personnel. The safety performance of arch bridges should not be deficient in order to ensure that they can effectively carry the required load within the set range. Cracks and concrete failure of arch bridges are the most common problems in arch bridges. At present, walking devices are mainly used to carry inspection personnel or inspection devices to carry out detailed inspections at the bottom of arch bridges. [0003] Yet all there are many problems in existing several running gears, below several existing running gears are introduced. [0004] The first type is the rubber wheel clip rail type walking device, which mainly relies on the friction force between the rubber wheel and the guide rail to realize the driving, and the drivin...
