Grease-saving steel wire rope with anti-throwing property

Abstract

The invention discloses a grease-saving steel wire rope with an anti-throwing property, and belongs to the technical field of steel wire rope equipment. It can be realized that when the steel wire rope is pressed, a movable sleeve with a plurality of magnets moves towards a second discharging hole, a sealing soft ball is driven to close the second discharging hole, and under the action of pressure, inner lubricating grease is discharged from a conveying cavity through a first discharging hole, so that the overflow amount and accuracy of the lubricating grease discharged when the steel wire rope is pressed are controlled; when the steel wire rope is restored in shape, a flexible grease control barrel pulls the movable sleeve with the multiple magnets to drive the sealing soft ball to roll for closing the first discharging hole, and the lubricating grease stored in a grease storage barrel is sucked through the second discharging hole and a suction mechanism under negative pressure for next use; an anti-throwing mechanism is arranged in a grease discharging taper pipe; and when the steel wire rope is in a bending sliding state, a gravity ball closes an end opening of the conveying cavity to reduce the throwing-out amount of the lubricating grease, and the service life of the steel wire rope is further prolonged.

Description

technical field [0001] The invention relates to the technical field of steel wire rope equipment, and more specifically relates to a grease-saving steel wire rope with anti-swing property. Background technique [0002] The steel wire rope is a spiral steel wire bundle twisted together with steel wires whose mechanical properties and geometric dimensions meet the requirements according to certain rules. The steel wire rope is composed of steel wire, rope core and lubricating grease. The steel wire rope is first twisted into strands by multi-layer steel wires, and then twisted into a helical rope by a certain number of strands with the rope core as the center. In material handling machinery, it is used for lifting, pulling, tensioning and carrying. The steel wire rope has high strength, light weight, stable operation, and is not easy to break suddenly, and the operation is reliable. In 1834, the European Olubert invented the world's first steel wire rope (smooth steel wire r...

Problems solved by technology

[0004] However, when the existing steel wire rope is under pressure, the steel wire will squeeze the inner rope core, causing a large amount of grease stored in the rope core to overflow from the surroundings. Although it can play a lubricating role, it is impossible to control the amount of grease overflow Undoubtedly, a large amount of lubricating grease is wasted. At the same time, in the case of rapid sliding at the bend of the steel wire rope, a small amount of lubricating grease will spill out at the outer bend, which will also lead to a sharp reduction of lubricating grease and seriously reduce the service life of the steel wire rope. Therefore, a kind of fat-saving steel wire rope with anti-shake property is proposed
