The utility model relates to an adsorption type curtain wall crawling robot self-adaptive foot, and relates to the field of crawling robots, the adsorption type curtain wall crawling robot self-adaptive foot comprises a foot shell, a bottom shell, a driving crawler wheel and an adjusting spring, the foot shell is of a barrel-shaped structure with one side provided with a bottom, the bottom shell is slidably connected to an opening of the foot shell, and the driving crawler wheel is installed at the inner bottom of the foot shell; the adjusting spring is arranged between the foot shell and the bottom shell, one end of the adjusting spring is fixed to the foot shell, the other end of the adjusting spring is fixed to the bottom shell, and a rubber bottom ring is arranged on the side, away from the foot shell, of the bottom shell. The glass curtain wall has the effect of reducing friction force generated when the rubber bottom ring makes contact with the glass curtain wall.

This invention relates to the field of medical and nursing device technology, and discloses a hammock-type assisted turning bed and a turning method, including a bed frame body. The bed frame body includes multiple functional segments arranged sequentially along its length. Each functional segment is equipped with a bed surface driving mechanism and a support adjustment mechanism. The bed surface driving mechanism includes a roller winding device and a bed surface. Two roller winding devices are symmetrically arranged on both sides of the bed frame body of the functional segment. The two ends of the bed surface are wound around the rollers of the corresponding roller winding devices. The support adjustment mechanism is located below the bed surface and includes multiple electric cylinders arranged along the width direction of the bed frame body. The hammock-type assisted turning bed and turning method provided by this invention solve the problems of high risk of shear friction injury, high risk of pressure sores, poor comfort, and insufficient safety and adaptability in the practical application of existing technologies.
