Precise positioning type grabbing equipment of crane and working method thereof

Abstract

The invention discloses precise positioning type grabbing equipment of a crane. The precise positioning type grabbing equipment of the crane comprises a mounting seat and grabbing mechanisms, the twosides of the bottom surface of the mounting seat are provided with strip-shaped fixing plates correspondingly, the two sides of the bottom surfaces of the two fixing plates are provided with the grabbing mechanisms correspondingly, a mounting plate is arranged on the bottom surfaces of the fixing plates, a first hydraulic cylinder is movably arranged on the side, away from the mounting seat, of the top surface of the mounting plate, the output end of the first hydraulic cylinder is movably connected with a connecting plate, the mounting plate is provided with a through hole matched with the connecting plate, the middle of the connecting plate sleeves a connecting shaft, the two sides of the connecting shaft are arranged on the bottom surface of the mounting plate through bearing seats correspondingly, shells are arranged on the two sides of the side wall of one fixing plate correspondingly, locking mechanisms are arranged in the shells, swing arms sleeve the two sides of the connectingshaft correspondingly, the other ends of the swing arms are connected with connecting seats, and the connecting seats are connected with gripper bodies through distance varying mechanisms. The precise positioning type grabbing equipment of the crane has the advantages that precise positioning can be performed for grabbing, and safety and stability are high during grabbing.

Description

technical field [0001] The invention belongs to the technical field of cranes, and relates to a grabbing device and a working method thereof, in particular to a crane's precise positioning grabbing device and a working method thereof. Background technique [0002] The grab bucket refers to the special tool for the crane to grab dry bulk cargo. [0003] The comparative document CN201720731358.0 discloses a grabbing mechanism for a crane, including a grabbing mechanism body, the grabbing mechanism body includes a telescopic arm, a guide hydraulic rod, a fixed plate, a main hydraulic cylinder, a main claw and a fixed shaft, and the fixed The middle part of the upper end of the plate is connected to the bottom of the telescopic arm through a hinge structure, and the lower end of the telescopic arm is connected to both sides of the upper end of the fixed plate through a guide hydraulic rod. The two ends are fixed by nuts, and the middle part of the buffer claw is sleeved on the ...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem in the prior art that the operator constantly adjusts and controls the position of the grippers when the crane is grabbing, so that the grippers can be more convenient and more evenly distributed on the grippers, so that The equipment and items of the gripper are more stable and stable, but the manual operation results in more human and material resources for the grabbing work, and it is also impossible to accurately locate the grabbing position of the equipment that needs to be grabbed; when the gripper is in progress In the process of grasping, there will be misgrasping, grasping is not firm or loose during the process of grasping and moving, so there will be safety hazards, and it will also cause certain damage to the equipment that needs to be grasped, affecting the need to grasp. Due to the problem of normal use of the equipment, a crane precise positioning grabbing equipment and its working method are proposed
