Embodiment Construction

[0032]When the robot advances, the third foot 9.1, the fourth foot 9.2, the fifth foot 10.1, the sixth foot 10.2, the fifteenth foot 15.1, the sixteenth foot 15.2, the seventeenth foot 16.1, and the eighteenth foot 16.2 are electrified. The electromagnet generates magnetic force and adsorbs to the inner wall of the pipeline, then the first leg 8.1, the second leg 8.2, the seventh leg 11.1, the eighth leg 11.2, the ninth leg 12.1, the tenth leg 12.2, the eleventh leg 13.1, and the twelfth leg 13.2, the thirteenth foot 14.1, the fourteenth foot 14.2, the nineteenth foot 17.1, and the twentieth foot 17.2 move forward under the drive of the motor, and when they reach the designated position, energize the electromagnet to absorb with the pipe wall. Three feet 9.1, fourth feet 9.2, fifth feet 10.1, sixth feet 10.2, fifteenth feet 15.1, sixteenth feet 15.2, seventeenth feet 16.1, and eighteenth feet 16.2. The spring is pulled back into the foot, and after completion, the motor revers...

Abstract

The invention discloses a nondestructive testing robot for pipes based on an electromagnetic principle, and belongs to the field of structural design. The nondestructive testing robot can adjust postures in real time to adapt to such conditions as pipe bending not beneficial to the climbing. The nondestructive testing robot is additionally provided with a magnetic absorbing device and a spherical connecting mechanism, so that the robot can climb in vertical pipes or bent pipes not beneficial to the climbing. The robot is stronger in pipe adaptability. The magnetic absorbing device is placed in a foot, and is connected with a spring; the spring is elongated and an electromagnet is absorbed on the pipe wall in electrification; and the spring is pulled back into the foot in power failure. Meanwhile, a flexible spring is mounted in the upper part in the foot, so that the foot has a certain adjusting capacity to adapt to the pipes with different diameters, and has a certain vibration reducing effect and obstacle crossing ability. When a leg is absorbed and fixed, the climbing action is finished by dint of relative actions of a body and the fixed leg. Through the absorption of the electromagnet, the electromagnet is absorbed on the pipe wall in electrification, the leg is fixed, and the body is advanced; and the electromagnet is pulled back into the leg by the spring in power failure, and the leg is movable.

Description

technical field [0001] The invention is a design of a crawling robot capable of completing non-destructive testing tasks under various pipeline shapes. It belongs to the field of structural design. Background technique [0002] Industrial piping systems have been widely used in fields such as metallurgy, petroleum, chemical industry and urban plumbing supply. The working environment of industrial pipelines is very harsh, and it is prone to corrosion, fatigue damage, or potential defects inside the pipeline to develop into damage and cause leakage accidents. The key to operation, in-service and on-line inspection of pipelines has become one of the important directions for the application and development of pipeline non-destructive testing technology. Therefore, the demand for pipeline inspection technology equipment is very urgent. However, the existing pipeline inspection robot relies on the guide wheels to control the steering and provide support. This design allows the...
