Composite steel wire rope lifting appliance and manufacturing method thereof

Abstract

The invention relates to the technical field of lifting appliances, in particular to a composite steel wire rope lifting appliance. The composite steel wire rope lifting appliance comprises a main base, a rotating groove is formed in the end part of the main base, a clamping mechanism is arranged on the inner side of the rotating groove, the clamping mechanism comprises a first clamping plate, a second clamping plate and a third clamping plate, the upper end of the first clamping plate is rotationally connected to the main base through the rotating groove and a rotating shaft, the upper end of the second clamping plate is rotationally connected to the lower end of the first clamping plate, and one end of the third clamping plate is rotationally connected to the lower end of the second clamping plate. Through the designed clamping mechanism, during use, a first clamping plate, a second clamping plate and a third clamping plate are driven by a first clamping air cylinder, a second clamping air cylinder and a third clamping air cylinder of the clamping mechanism to clamp an object, during the clamping, the first clamping plate, the second clamping plate and the third clamping plate rotate for multiple times so as to clamp the object at multiple angles, so that the lifting appliance is stabler and convenient when fixing the object.

Description

technical field [0001] The invention relates to the technical field of slings, in particular to a composite steel wire rope sling and a manufacturing method thereof. Background technique [0002] The spreader refers to the device for lifting heavy objects in the hoisting machinery. The most commonly used lifting tools for lifting items are hooks and slings, and others include rings, lifting suction cups, clamps and forks. It is widely used in the lifting industry. Special rigging such as hooks, wire ropes, and chains are commonly used in the spreader. Lifting suction cups, clamps and forks can be used as special spreaders on the crane for a long time, and can also be used as replaceable auxiliary spreaders hanging on the hook for temporary use. They are often used in multi-cargo warehouses and yards to improve work efficiency. The spreader for grabbing bulk materials is generally a grab bucket with a jaw plate that can be opened and closed, and an electromagnetic chuck c...
