Multi-peel grab bucket with variable capacitance

Abstract

The invention relates to a multi-peel grab bucket with variable capacitance and specifically to a multi-peel grab bucket device capable of changing the volume of a grab bucket, belonging to the technical field of lifting and handling equipment. According to the invention, a supporting rope is arranged at two ends of an equalizer beam, and an upper bearer is arranged below the equalizer beam; a guide rod assembly is provided at the upper end of the upper bearer, an upper pulley is arranged on the upper bearer, a lower pulley is arranged on a lower bearer, and the upper pulley and the lower pulley are connected with each other by passing through an open-and-close rope on the guide rod assembly; the upper end of an strut is connected with the upper bearer; a grab bucket body is connected with the lower end of the strut; a sleeve pedestal is arranged on the lower bearer, and a multi-level sleeve is connected with the lower end of the sleeve pedestal. The multi-peel grab bucket provided in the invention has a simple, compact and reasonable structure; the multi-peel grab bucket can be used for materials with different proportions, thereby realizing the purpose of multi-usage of the grab bucket, eliminating the problem of replacement of grab buckets for different materials, preventing overload, reducing the amount of configured grab buckets and saving cost.

Description

technical field [0001] The invention relates to a variable-capacity multi-lobe grab, in particular to a multi-lobe grab device capable of changing the volume of the grab, and belongs to the technical field of lifting and unloading equipment. Background technique [0002] In the prior art, the multi-lobe grab does not have a variable bucket capacity structure. When grabbing materials, it cannot be used universally among materials with different specific gravity. For example, using a grab bucket to grab materials with a large specific gravity such as ore to grab materials with a small specific gravity is seriously inefficient; grabbing a grab bucket with a small specific gravity such as coal to grab materials with a large specific gravity will seriously overload. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a variable-capacity multi-lobe grab bucket, which can realize common use among mater...

AI Technical Summary

Problems solved by technology

When grabbing materials, it is impossible to achieve common use among materials with different specific gravity

For example, if a grab bucket is used to grab materials with a large specific gravity such as ore to grab materials with a small specific gravity, the efficiency is seriously low; if a grab bucket with a small specific gravity such as coal is used to grab materials with a large specific gravity, it will be seriously overloaded.
