Adjustable grab bucket based on parallel mechanism control

Abstract

The invention relates to the field of hexagonal grab buckets, in particular to an adjustable grab bucket based on parallel mechanism control. The adjustable grab bucket comprises a connecting body, a parallel adjustment device, a position control hydraulic cylinder and grab bucket bodies. The connecting body is connected with the parallel adjustment device and used for connecting the grab bucket with the outside. The parallel adjustment device is located below the connecting body and used for adjusting the working positions of the grab bucket bodies. The position control hydraulic cylinder is located inside the parallel adjustment device and used for adjusting the positions of the grab bucket bodies in cooperation with the parallel adjustment device, and the two ends of the position control hydraulic cylinder are connected with the parallel adjustment device. The grab bucket bodies are installed on the lower portion of the parallel adjustment device and can be detached to be replaced. With a parallel mechanism as the design basis, adaptive adjustment can be performed according to different grab targets, and therefore the target grab quality and efficiency of an existing grab bucket can be obviously improved.

Description

technical field [0001] The invention relates to the field of hexagonal grabs, in particular to an adjustable grab based on parallel mechanism control. Background technique [0002] At this stage, the development of the grab industry is changing with each passing day, and the functions of the grab are gradually increasing. Many aspects of the grab technology can be said to be quite mature. However, the grab still faces many problems in the process of use. For example, the existing grab During use, most grabs cannot change the grabbing method and grabbing contact point according to the type and nature of the grabbing target bucket. A small number of grabbing buckets are assisted by various external devices to complete the transformation grabbing, while Through experiments, it is found that different grabbing forms and grabbing tools have a more obvious impact on the quality of grabbing. In view of such problems, we can see that the grabs involved in the prior art are far from ...
