Description

Double-rope multi-petal nickel ore grab bucket

Technical Field

The utility model relates to a grab bucket technical field specifically is a two cable orange-nickel ore grab buckets.

Background

Grab buckets are bulk cargo handling devices commonly used in port and wharf, power plants and other transportation industries, and are well known to be composed of bucket flaps, upper bearing beams, fixed pulley blocks, lower cross beams, movable pulley blocks, support rods, rope guide wheels, balance frames, steel wire ropes and the like. Due to the difference of the multiplying power of the grab bucket, the pulley block comprises pulleys with different numbers. The steel wire rope is driven by the pulley to close and open the bucket flap.

Along with the development of the import and export port trade, the transportation volume of nickel ore by ports is increased. Because the nickel ore has strong viscosity and is difficult to grab, the actual bucket capacity used in the grabbing process of the conventional six-petal and double-jaw bucket is only about half of the theoretical capacity, namely about one third of the materials are stuck on the inner wall of the bucket body and are repeatedly transported. The nickel ore is easy to agglomerate under the condition of being extruded, particularly, the bonded granularity of the air-dried nickel ore is large and hard, and the common multi-petal grab bucket is difficult to cut into the three-combined soil, so the ship unloading efficiency is very low.
