Abstract

The magnetofluid damping joint comprises an upper limb, a lower limb and a bowl-shaped middle joint, the upper limb comprises an upper cylinder and a lower sphere, a camera is installed at the top end of the upper cylinder, the lower sphere is located in the middle joint, an upper coil is arranged in an inner cavity of the lower sphere, and a lower coil is arranged in an inner cavity of the lower sphere. The bottom of the lower ball body is flexibly connected with the inner bottom wall of the middle joint through a spring, and an inner magnetorheological cavity filled with magnetorheological fluid is formed between the inner wall of the middle joint and the periphery of the lower ball body; the lower limb comprises an upper shell and a lower column body, the middle joint is located in the upper shell, an outer magnetorheological cavity filled with magnetorheological fluid is formed between the middle joint and the inner wall of the upper shell, the middle joint can rotate or be instantly fixed in the inner magnetorheological cavity and the outer magnetorheological cavity, an annular cavity is formed in the upper shell, a lower coil is arranged in the annular cavity, and the lower coil is connected with the lower column body. And the lower column body is mounted on the inspection robot main body.

Description

technical field [0001] The invention relates to the technical field of shock absorption for robots, in particular to a magnetic fluid shock absorption joint for a camera bracket of an inspection robot. Background technique [0002] The inspection robot uses a mobile robot as the carrier, and a camera, infrared thermal imager and other detection instruments as the load system. The device used to carry the camera is a pan-tilt, which can be lifted and lowered in a large range during the inspection process. At present, the inspection robot used in underground coal mines is different from the daily indoor and outdoor inspection robot. During the underground work, it will encounter harsh ground conditions, causing large vibrations in the main body of the inspection robot, which is then transmitted to the cloud platform The camera on the camera greatly affects the clarity of the image captured by the camera. Therefore, the changeable underground road conditions put forward higher...
