Travelling mechanism of track inspection robot

Abstract

The invention discloses a travelling mechanism of a track inspection robot. The travelling mechanism comprises a track and a driving mechanism, the driving mechanism moves along the track, and the inspection robot is installed on the driving mechanism; the track comprises an aluminum profile and a chain which is arranged under the aluminum profile in parallel; the driving mechanism comprises suspension arms, a cross beam, a steady wheel set, a chain wheel, a driving motor and a steering device, a U-shaped structure is formed by the two suspension arms and the cross beam, the suspension arms make slideable contact with the aluminum profile through the steady wheel set, the chain wheel is horizontally arranged and rotationally connected with the cross beam, the chain wheel meshes with the chain, a torque input shaft of the chain is fixedly connected with a torque output shaft of the driving motor through a transmission belt, and the driving motor is fixedly connected with the cross beam.In the travelling mechanism, the standard industrial aluminum profile is used as the track, the chain is used as a path, the chain wheel is used as a driving wheel, and a chain-drive mode is adoptedso that precise positioning can be achieved, and turning and climbing can be easily achieved; the steering shaft is adopted as a steering knuckle so that the requirements for small-radius turning canbe met.

Description

technical field [0001] The invention relates to a robot walking mechanism, in particular to a track inspection robot walking mechanism. Background technique [0002] At present, robots are used more and more widely. In the occasions that have certain requirements for safety, more and more robots that walk along the track are used. Most of the currently used tracks follow the I-shaped track of the self-propelled conveying robot. There is a situation that the weight is large, the price is high, and it is difficult to realize a small radius turning. In places where equipment is dense, such as power rooms, it is difficult to meet actual needs. Therefore, it is necessary to develop a robot with low price, reliable walking and small turning radius. The prior art mainly advances by the self-friction of the driving wheel, or by the racks laid on the track, and advances through the meshing of the gears. [0003] The friction form is adopted because it relies on wheel friction, a...

Problems solved by technology

[0003] The friction method is used because it relies on wheel friction, and it is difficult to achieve precise positioning due to slippage

However, the form of rack and pinion will not slip, but it is not easy to turn and climb, and the cost of the rack is relatively high
