Abstract
A material gripping apparatus with a device for automatically adjusting the sectional area is provided to overcome the defects that circular materials with different diameters are bound and hoisted by steel wire ropes or other ropes and are easy to wear, the loading and unloading efficiency is low, the labor intensity of workers is high, people and goods are not separated, and the material gripping apparatus is not safe. The gripping apparatus can be assembled on engineering machinery, and the rotation of the 360-degree rotator of the gripping apparatus and the extension of the claw arm hydraulic cylinder are controlled by utilizing an external control valve, so that the material loading and unloading directions of the gripping apparatus and the opening and closing of the claw arm of the gripping apparatus can be adjusted at will. The automatic adjusting device for the sectional area of the gripper comprises a hydraulic oil cylinder of an adjusting device frame, the adjusting device frame and a gripper vertical frame, wherein the hydraulic oil cylinder of the adjusting device frame, the adjusting device frame and the gripper vertical frame are assembled on the gripper, and the external control valve is utilized to control the hydraulic oil cylinder of the adjusting device frame to stretch and retract so as to adjust the sectional area of the gripper in a closed state.
Description
Technical Field
The invention relates to a material gripping apparatus with a device capable of automatically adjusting the sectional area.
Background
With the rapid development of economy in China, the continuous investment of the nation on the infrastructure of high-speed rails, expressways, bridges and the like, the demand of various raw materials is increasing day by day. Wherein, the promotion of various raw and other materials transportation turnover efficiency can accelerate the progress of project construction greatly. As is well known, the current circular material modes of railway station goods yard and port and dock, especially the circular material with long steel length and inconsistent diameter, are generally to hook the steel wire rope buckle or other ropes for wrapping and hanging the material by the hook of a crane, the material to be hung is bound firmly by the steel wire rope or other ropes firstly and then is hung on a transport vehicle, the loading direction of the material is adjusted by manual rotation, the steel wire rope or rope also needs to be loosened manually during the unloading, the whole hanging process is operated by a plurality of people in a matching way, the direction is adjusted by manual direct contact with the material during the hanging, the accidents and the casualties are easily caused, and the work efficiency of the whole pipe loading and unloading process is low, the people and the goods are not separated and unsafe.
The invention aims to overcome the defects of the prior art, and the material gripping apparatus provided with the device for automatically adjusting the sectional area mainly solves the problems of complex operation, high danger, low work efficiency and the like in the existing process of loading and unloading circular materials with inconsistent diameters
The invention adopts the specific technical scheme that: the utility model provides a be furnished with material gripping apparatus of automatic adjustment sectional area size device, has 360 rotators of gripping apparatus, hydraulic pressure center swivel joint, gripping apparatus grudging post, claw arm hydraulic cylinder, adjusting device frame, interior claw arm and outer claw arm, and its key point lies in: the 360 rotators of gripping apparatus and gripping apparatus grudging post use bolt erection joint: the inner claw arm and the outer claw arm are connected with the gripping apparatus vertical frame through pin shafts; two ends of the claw arm hydraulic oil cylinder are respectively connected with the gripping apparatus vertical frame, the inner claw arm and the outer claw arm by pin shafts; the hydraulic oil cylinder of the adjusting device frame and the adjusting device frame are connected with the vertical frame of the gripping apparatus by pin shafts. The 360-degree rotator of the gripping apparatus can be installed and connected with engineering machinery by using a pin shaft.
The technical scheme is characterized in that: the 360-degree rotator of the gripping apparatus can be installed and connected with engineering machinery by using a pin shaft. The hydraulic oil cylinder of the adjusting device frame, the adjusting device frame and the gripping apparatus vertical frame are connected and installed, and the gripping apparatus is assembled to form an automatic area size adjusting device.
Compared with the prior art, the gripper can be installed on engineering machinery for use, the external control valve is utilized to control the 360-degree rotator of the gripper to rotate and the claw arm hydraulic cylinder to stretch, and the material loading and unloading directions of the gripper and the opening and closing of the claw arm of the gripper can be adjusted at will. The automatic adjusting device for the sectional area is composed of an adjusting device frame hydraulic oil cylinder, an adjusting device frame and a gripping apparatus vertical frame which are assembled on the gripping apparatus, an external control valve is utilized to control the hydraulic oil cylinder of the adjusting device frame to stretch and retract, and the adjusting device frame is adjusted to be folded and unfolded randomly, so that the sectional area of the gripping apparatus in a closed state is adjusted, round materials with different diameters can be effectively solved, and the gripping apparatus is simple in structure, convenient to use, low in labor intensity of workers, capable of separating people from goods, safe and reliable.
