The utility model discloses a kind of universal coupling based on card column type telescopic cross axle, including card column type cross axle, the telescopic cavity is evenly provided in the inside of card column type cross axle four corners, telescopic column is installed in the telescopic cavity, and telescopic spring is fixed between the telescopic column and the card column type cross axle.Affinity effect lies in: the utility model is by setting a group of by operating mechanism of push block, telescopic sealing plate, locking bolt and positioning hole composition, in assembling process, by push block telescopic column is moved to compression to telescopic spring, make it easy to assemble, and telescopic sealing plate is sealed to cavity at the same time again without affecting the moving performance of push block, and it can be realized to the fixing of telescopic column after adjustment by locking bolt and positioning hole combination, on the one hand, it is convenient for staff to assemble operation, and safety factor is high, on the other hand, it can be guaranteed to avoid the influence of telescopic spring on transmission performance in use process, guarantee its use performance.

The application discloses a steel structure inner cavity magnetic wall-climbing robot welding seam defect positioning device and method, belongs to the technical field of defect positioning, solves the problem that the existing wall-climbing robot cannot effectively adsorb and stably travel on the inner cavity of a complex-shaped steel structure, and leads to insufficient defect detection adaptability, and comprises a positioning device main body, a magnetic travel mechanism and a self-cleaning defect positioning mechanism, wherein the magnetic travel mechanism comprises a combined magnetic wheel, a self-adaptive protection assembly and a damping reset assembly; in the application, the combined magnetic wheel, the wheel driving motor and the self-adaptive protection assembly are cooperatively matched to non-rigidly fix the combined magnetic wheel, and the combined magnetic wheel is hung in a robot moving seat through the self-adaptive protection assembly; when the robot encounters a recess or a protrusion of an inner cavity wall surface, the corresponding combined magnetic wheel will self-adaptively float up and down, thereby actively adhering to the wall surface, so as to adapt to the inner cavity wall of a steel structure of different shapes and ensure that the robot can be stably adsorbed on the inner wall in the whole process.
