Problems solved by technology
[0002] The contact area between the electromagnetic adsorption device and the magnetic object is an important factor affecting the magnetic force of the electromagnetic adsorption device. If the contact area between the electromagnetic adsorption device and the magnetic object is too small, the adsorption performance of the electromagnetic adsorption device will be greatly reduced, which will seriously affect the electromagnetic adsorption device. For the use of equipment connected to the device, if necessary, it is necessary to increase the current of the electromagnetic adsorption device to increase the magnetic force of the electromagnetic adsorption device
[0003] Especially for detection equipment or crawling robots adsorbed on the wall of magnetically permeable circular pipes, refer to figure 1 , because the cross-section of the magnetically conductive circular pipe 1 is circular, and the existing electromagnetic adsorption device is mainly an electromagnetic chuck 2, the magnetic adsorption surface of the electromagnetic chuck is a plane, so the electromagnetic chuck cannot be adaptively increased to match the magnetically conductive circular shape. The contact area of the wall of the pipe makes the electromagnetic chuck and the wall of the magnetic circular pipe only in line contact, which will easily cause the detection equipment or crawling robot to fall. If the current of the electromagnetic chuck is increased, the electromagnetic chuck will be increased. Risk of overload burnout

The invention discloses a self-adaptive electromagnetic adsorption device which comprises a shell and at least two electromagnetic supporting legs, wherein at least two limiting chutes distributed left and right in a spaced manner are separately formed in the front and back side faces of the shell, and a guide pin provided with a spring in a sleeving manner is arranged in each limiting chute; eachelectromagnetic supporting leg is in spline connection to a rotating shaft and is rotatably connected between the front and back limiting chutes through a corresponding rotating shaft, and two end parts of each rotating shaft are in contact with the corresponding spring. As all the electromagnetic supporting legs are movably arranged, the position of each electromagnetic supporting leg driven bya magnetic force is adaptively adjusted when the self-adaptive electromagnetic adsorption device is close to a magnetoconductive round pipeline, so that each electromagnetic supporting leg can be in contact with the magnetoconductive round pipelines of different dimensional specifications to the maximum extent, and therefore, the magnetic force between the self-adaptive electromagnetic adsorptiondevice and the magnetoconductive round pipeline is improved.
