Walking driving and supporting device for bridge detection operating vehicle

Abstract

The invention discloses a walking driving and supporting device for a bridge detection operating vehicle. The walking driving and supporting device mainly comprises a bracket assembly, a hydraulic driving and bearing device, a driving wheel assembly and a driven wheel assembly, wherein the bracket assembly comprises a supporting bracket, a groove-shaped bracket and a groove-shaped wheel carrier; the groove-shaped wheel carrier is a groove-shaped frame with a downward notch; the hydraulic driving and bearing device mainly comprises a hydraulic motor, a supporting hydraulic oil cylinder, a bidirectional hydraulic lock, a motor control valve and an oil cylinder control valve; a driving wheel assembly is arranged on a left side inside the groove-shaped wheel carrier and mainly comprises a driving wheel hub, a driving wheel sleeve, a short shaft, an end cover and a planetary gear reducer; and the driven wheel assembly is arranged on a right side inside the groove-shaped wheel carrier and mainly comprises a driven wheel hub, a driven wheel shaft and a driven wheel sleeve. Supporting and stabilizing effects can be achieved, and driving force can be supplied to a movable machine needed byoperation. The walking driving and supporting device has high bearing rigidity, high bearing capability, high wear resistance, a simple structure and long service life, and is safe and reliable.

Description

technical field [0001] The invention relates to a traveling driving support device, in particular to a traveling driving and supporting device suitable for a bridge detection operation vehicle. Background technique [0002] In the process of bridge inspection, maintenance and reinforcement, the bridge inspection vehicle must have outriggers to ensure the stability and safety of the whole machine, and it is also necessary to realize the linear movement of the whole machine along the longitudinal direction of the bridge. At present, the outrigger device used in the bridge inspection vehicle mainly has the following problems: first, the locking performance of the oil cylinder used to retract and release the outrigger is poor, and it is easy to fall due to its own weight and vibration when walking, and The unsafe phenomenon of insufficient supporting force during operation; second, there is no self-propelled driving function, which makes it very inconvenient to move the machine ...

AI Technical Summary

Problems solved by technology

At present, the outrigger device used in the bridge inspection vehicle mainly has the following problems: first, the locking performance of the oil cylinder used to retract and release the outrigger is poor, and it is easy to fall due to its own weight and vibration when walking, and The unsafe phenomenon of insufficient supporting force during operation; second, there is no self-propelled driving function, which makes it very inconvenient to move the machine during the inspection operation; third, the material selection of the parts in contact with the ground is unreasonable, with weak bearing capacity and poor wear resistance; Fourth, the structural design does not consider the tribological requirements, and dust easily enters the friction pairs such as the bearings, which affects the service life and reliability
