Problems solved by technology

[0002] In the prior art, when the grab uses a triple-rate operating mechanism, the work efficiency of grabbing materials is high, but when grabbing some materials, the closing force of the grab is not enough, and the closing time of the grab is short, resulting in poor grabbing effect. Difference
When the grab is operated with a four-fold operating mechanism, the closing force of the grab is sufficient, and the closing time is longer, so the grabbing effect is better, but the work efficiency is not high when grabbing some materials

Abstract

The invention relates to a universal mechanism for realizing triple or quadruple operation of a grab bucket, which is particularly used for the triple or quadruple universal operation of the grab bucket and belongs to the technical field of crane equipment. The universal mechanism mainly comprises an upper support beam, a lower support beam, a support rod, a bucket body, an opening and closing rope, a guide wheel, an upper pulley block and a lower pulley block, wherein the upper support beam is hinged and connected with the upper end of the support rod, and the lower end of the support rod is hinged and connected with the side surface of the bucket body. The upper end of the bucket body is hinged and connected with the lower support beam. The universal mechanism has the advantages that the structure is simple, compact and reasonable, a better grabbing effect can be realized during the grabbing of different materials, the work efficiency of the grab bucket can also be improved, meanwhile, the triple or quadruple operation requirements can be met, the operation is convenient, and the cost of equipment is reduced.

Description

technical field [0001] The invention relates to a general-purpose mechanism for three-to-four-fold operation of a grab bucket, in particular to the general-purpose operation of three-to-four-fold operation of a grab bucket, and belongs to the technical field of crane equipment. Background technique [0002] In the prior art, when the grab uses a triple-rate operating mechanism, the work efficiency of grabbing materials is high, but when grabbing some materials, the closing force of the grab is not enough, and the closing time of the grab is short, resulting in poor grabbing effect. Difference. When the grab uses a four-fold operating mechanism, the closing force of the grab is sufficient, and the closing time is longer, so the grabbing effect is better, but the work efficiency is not high when grabbing some materials. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, thereby providing a general mechanism for gr...
