Embodiment Construction

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0019] see figure 1 and 2 , four-cable eight-petal nickel ore grab, including bucket petals 01 connected to the lower end of the strut 04, the upper end of the strut 04 is rotatably connected to the upper bolster 02 through a pin shaft, and the upper bolster 02 is set on the load-bearing cable balance frame 05 On the top, the upper bolster is provided with a fixed pulley block 06; the upper end of the bucket petal 01 is hinged with the lower bolster 07, and the lower bolster is provided with a movable pulley block 03, and the fixed pulley block 06 and the movable pulley block 03 are connected by connecting members. It is a conventional structure and will not be described in detail here.

[0020] In the present invention, there are eight buc...

Abstract

The invention discloses a four-cable eight-piece nickel mineral grab bucket which comprises eight bucket flaps, wherein the bucket flaps are connected with support rods; the upper ends of the support rods are rotatably connected with an upper bearing beam through pin rolls; the upper bearing beam is arranged on a track cable balancing stand; a fixed pulley group is arranged on the upper bearing beam; the upper ends of the bucket flaps are hinged to a lower bearing beam; a movable block group is arranged on the lower bearing beam; the fixed pulley group is connected with the movable block group through a connecting component; the bucket flaps are combined to form a closable entirety; each bucket flap is connected with the upper bearing beam through a corresponding support rod, and is hinged to the lower bearing beam. According to the invention, the number of the bucket flaps is changed into eight, so that the stability of the entire grab bucket is higher, and the appearance is more symmetrical; according to the top view of the entire grab bucket, the bucket flap integrity is a hexadecagon and similar to a circle, so that the strength of a single bucket flap is increased, and the actual contact range between a material and each bucket flap is reduced so as to reduce the bucket flap bonding area.

Description

technical field [0001] The invention relates to a grab bucket, in particular to a nickel ore grab with four ropes and eight petals, which is especially suitable for nickel ore bulk materials with high viscosity, easy to agglomerate, poor fluidity and difficult to grab. Background technique [0002] The grab bucket is a bulk cargo handling device commonly used in the transportation industries such as ports, power plants, etc. As we all know, the grab bucket is composed of bucket flaps, upper bearing beams and fixed pulleys, lower beams and movable pulleys, struts, and guide ropes. wheel, balance frame, steel wire rope and so on. Due to the difference in grab ratio, the pulley blocks contain different numbers of pulleys. The steel wire rope is driven by the pulley to make the bucket flaps close and open. [0003] With the development of import and export port trade, the port's transportation volume of nickel ore has increased. Due to the strong viscosity of nickel ore, it i...
