The invention discloses an air pressure grab bucket which comprises a moving and lifting device and a grab bucket device, wherein the grab bucket device comprises an air cylinder and two bucket bodies, and is suspended on the moving and lifting device; the top of each bucket body is provided with two supports which are in symmetrical arrangement and of inverted U shapes; middle parts of the two supports are articulated; the two bucket bodies are arranged symmetrically in a mode of opposite openings and are respectively fixedly connected to the two supports; two ends of the air cylinder are respectively articulated with the top parts of the two bucket bodies or are respectively articulated with two ends of the inverted-U-shaped supports so as to form a structure for controlling the opening and closing through the stretching of the air cylinder. The grab bucket manufactured by adopting the structure has the advantages of simple structure and low production cost; and additionally the grab bucket can be suspended on an overhead vehicle for operation by adopting air pressure driving, and the oil leakage problem can not happen.
Description
technical field [0001] The invention relates to a grab bucket, in particular to an air pressure grab bucket suspended on a crane. Background technique [0002] In the prior art, grabs are generally driven by hydraulic cylinders. This type of hydraulic grab has a large grabbing force and is generally used for grabbing large particle materials. Hydraulic grabs are hydraulic structural parts. , Bucket (jaw plate), connecting column, bucket ear plate, bucket ear cover, bucket teeth, tooth seat and other spare parts. The hydraulic grab is a special industry equipment accessory that requires special equipment to produce, such as: CNC plasma cutting machine, Groove edge milling machine, plate rolling machine, welding positioner, boring machine, hydraulic test bench, etc.; the hydraulic grab needs to be assembled on professional hydraulic equipment to work, such as hydraulic excavator, hydraulic lifting tower, etc. From the above introduction to the hydraulic grab, it can be known ...
