Problems solved by technology

[0005] However, at present, wheeled magnetic adsorption wall-climbing robots mostly rely on the speed difference between the two sides to achieve steering. When steering, a large steering space is required, and it cannot be very flexible and fast to perform small-scale steering, and it is prone to wheel slippage. It is not convenient when working in a space with limited area

Embodiment 1

[0024] figure 1 It is a structural diagram of a steering device of a wheeled magnetic adsorption wall-climbing robot, which includes a wheeled combined moving device 1 and a permanent magnetic adsorption device 2;

[0025] The wheeled combined mobile device 1 includes a chassis 11, and a central driving wheel 12 and four passive universal wheels 13 respectively mounted on the chassis 11. The central driving wheel 12 can be driven by a driving motor through a chain structure or a gear device. Drive, adjust the direction by turning the top gear of the central driving wheel 12; Steering and moving, four passive universal wheels 13 cooperate with the central drive wheel to make the steering flexible.

[0026] The permanent magnetic adsorption device 2 is installed on the chassis 11. It uses permanent magnet materials to adsorb the magnetically conductive wall surface in a non-contact manner. The magnet can be increased or decreased according to actual needs, and the utilization r...

Embodiment 2

[0032] The steering device of the above-mentioned wheeled magnetic adsorption wall-climbing robot is different from this embodiment in that the wheel hub of the central drive wheel is made of permanent magnet material, which increases the adsorption force between the robot and the wall and ensures that the central drive wheel and the wall are fully connected. Contact, control direction.

Embodiment 3

[0034] The difference between the steering device of the above-mentioned wheeled magnetic adsorption wall-climbing robot in this embodiment is that the wheel hub of the universal wheel is made of non-magnetic material, which makes it more flexible during the steering process.

Abstract

The invention discloses a steering device of a wheeled magnetic attraction wall-climbing robot. The steering device comprises a wheeled combined moving device and a permanent magnet attraction device. The wheeled combined moving device comprises a chassis, a center driving wheel and four driven universal wheels, wherein the center driving wheel and the driven universal wheels are installed on the chassis, the driven universal wheels can rotate freely by 360 degrees, and flexible steering can be achieved; the permanent magnet attraction device connected with the chassis through threads is made of a permanent magnet material and attracts a magnetic conductive wall in a non-contact mode. In this way, the wheeled combined moving device and the permanent magnet attraction device are combined to make the robot attracted to the wall through the permanent magnet attraction device, the center driving wheel drives the robot to walk, and meanwhile the universal wheels capable of rotating freely by 360 degrees improve the steering flexibility, so that steering is fast, and the steering area is small.

Description

technical field [0001] The invention relates to the field of magnetic adsorption technology, in particular to a steering device for a wheeled magnetic adsorption wall-climbing robot. Background technique [0002] The wall-climbing robot can replace humans to move flexibly on inclined and vertical surfaces, giant components, and even the top of the container, and complete certain tasks. Wall-climbing robots have broad application prospects in petrochemical, building cleaning, shipbuilding, fire fighting and other fields. [0003] The magnetic adsorption wall climbing robot is a branch of the wall climbing robot. Although it is limited to the application of the magnetic wall surface, it has the advantages of strong adsorption force, not limited by the unevenness or cracks of the wall surface, safety, stability and reliability. Extensive research and application. [0004] At present, the mobile modes of magnetic adsorption wall-climbing robots mainly include crawler type, leg...
