Intelligent grab bucket capable of balancing hanging gravity center of grabbed goods and use method thereof

Abstract

The invention provides an intelligent grab bucket capable of balancing the hanging gravity center of grabbed goods and a use method thereof. The intelligent grab bucket comprises four supports; a transverse frame is fixedly connected to the upper surfaces of the two supports located at the left end; a first sliding groove is formed in the upper end of the right surface of the transverse frame; a second sliding groove is formed in the lower end of the right surface of the transverse frame; the left and right two pairs of supports are placed oppositely; a first circular groove is formed in the middle part of the plate surface of a first transverse plate, so that a time interval exists between the descending of a vertical rod and the descending of a second transverse plate, the unfolded grab bucket can conveniently extend into a to-be-grabbed material pile to press a lantern ring downwards; four connecting rods are gradually unfolded along with the downward movement of the lantern ring, the four connecting rods push moving blocks to move in first arc-shaped grooves through short rods, rectangular blocks, circular rings and round rods, in this way, the four combined parts move close to the lower arc surfaces of the arc-shaped rods and are gradually closed, the grabbing action is completed, closing of the grab bucket is completed through pressure brought by the downward sliding action of the second transverse plate, energy consumption is reduced, and the operation can be automatically completed without operator control.

Description

technical field [0001] The invention relates to the technical field of grab equipment, in particular to an intelligent grab capable of balancing the hanging center of gravity of goods and a usage method thereof. Background technique [0002] The grab bucket refers to the special tool for the crane to grab dry bulk cargo. The storage space is composed of two or more bucket-shaped jaws that can be opened and closed. When loading, the jaws are closed in the material pile, and the materials are grabbed into the storage space. When unloading, the jaws are in the pile. When it is opened in the suspended state, the material is scattered on the pile, and the opening and closing of the jaw plate is generally controlled by the steel wire rope of the hoisting mechanism of the crane. There is no heavy manual labor in the grab operation, which can achieve high loading and unloading efficiency and ensure safety. It is the main dry bulk cargo loading and unloading tool in the port.

AI Technical Summary

Problems solved by technology

[0004] (1): To operate any operation, it is necessary to lift the grab to the height of the working position first, and then control the driving device to control the closing of the grab to complete the grab action. It is necessary to install a driving device on the grab to provide the power required for the grab to close. High maintenance cost

[0005] : In the process of closing and unfolding the grab, it needs to sweep the space under the grab to complete the grab action, which needs to occupy a space larger than the volume of the grab
