The invention relates to a vacuum negative pressure adsorption device and a multi-legged robot, the vacuum negative pressure adsorption device comprises a hard suction cup, the hard suction cup comprises a concave containing space, a mounting through hole is formed in a top plate of the hard suction cup, a vent hole is formed in the side edge of the mounting through hole, the lower end of the hard suction cup can be attached to an adsorption surface, and the hard suction cup cannot deform; the pneumatic piston is movably arranged in the accommodating space, and the accommodating space is divided into a negative pressure cavity and a ventilation cavity by the pneumatic piston; the electro-hydraulic actuator is fixedly connected with the top plate, the electro-hydraulic actuator comprises a non-inductive control motor and a hydraulic pump which are arranged in an integrated valve block, the integrated valve block is communicated with a hydraulic cylinder, and a piston rod of the hydraulic cylinder penetrates through the mounting through hole to be connected with the pneumatic piston. The tail ends of supporting legs of the multi-legged robot are connected with adsorption devices. The adsorption device is small in size and flexible to use, the long-time adsorption effect can be maintained, and the multi-legged robot can be suitable for wall climbing and is flexible in movement and high in stability.
Description
technical field [0001] The invention relates to the technical field of adsorption devices, in particular to a vacuum negative pressure adsorption device and a multi-legged robot. Background technique [0002] Vacuum suction cup is one of the actuators of vacuum equipment, which can be adsorbed on surfaces such as glass and ceramic tiles for hanging or grabbing objects. Because the vacuum chuck can move and change positions at will, it has been widely used in metallurgy, building materials, machinery manufacturing, medical treatment and other fields. [0003] Vacuum suction cups in the prior art are generally made of plastic materials with certain rigidity and flexibility such as silicone rubber or PVC material, polyurethane or nitrile rubber or vinyl-containing polymers. The structure of the vacuum suction cup is a hollow cone, and the wall surface of the suction cup facing the surface of the adsorbate is a cone with the middle part sunken upward. [0004] Generally, there...
