Eight-rope large orange-peel bucket

Abstract

The invention relates to an eight-rope large orange-peel bucket. The eight-rope large orange-peel bucket comprises a bucket body, a lower bearing beam, lower pulley blocks, a support rod, upper pulley blocks, an upper bearing beam, bearing steel wire ropes and opening and closing steel wire ropes, and is characterized in that two ends of the upper bearing beam are directly connected with the bearing steel wire ropes; two lower pulley blocks and two upper pulley blocks are arranged; the lower pulley blocks are arranged on the lower bearing beam side by side along the width direction of the bucket body; the upper pulley blocks are arranged on the upper bearing beam along the width direction of the bucket body; upper and lower positions of the two lower pulley blocks and the two upper pulley blocks correspond; four opening and closing steel wire ropes are arranged and respectively wound on the upper pulley blocks and the lower pulley blocks with corresponding upper and lower positions; rope ends of the four opening and closing steel wire ropes penetrate through the upper bearing beam upwards respectively. The eight-rope large orange-peel bucket is simple, compact and reasonable in structure; the eight-rope large orange-peel bucket is dragged by using eight ropes, so that the stress of the single steel wire rope is reduced; meanwhile, the steel wire ropes are of multi-point connection, so that the eight-rope large orange-peel bucket is even in stress, good in stability in air, especially applicable to underwater operation and favorable for improving the working efficiency.

Description

technical field [0001] The invention relates to a large eight-rope multi-lobe grab bucket, which belongs to the technical field of lifting and unloading equipment. Background technique [0002] At present, more and more grabs are used in channel dredging, sediment excavation and underwater salvage projects, but traditional grabs are mainly used in freight terminals, port machinery plants, power plants, shipyards, steel mills and other industries , used to grab various bulk cargo. The effect of applying it directly to underwater operations is not good, and there are mainly disadvantages such as large and uneven stress on the wire rope, poor stability in the air, and low work efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a large-scale multi-lobe grab with eight ropes. Point connection, uniform force, good stability in the air, especially suitable for underwater operations, wh...
