Winch with angle-adjustable winding drum axis

Abstract

The invention provides a hoist with an adjustable angle of the drum axis, which includes a drum, a frame and a steel wire rope. One end of the frame is hinged on a carrier supporting the hoist, and the other end is connected to the carrier supporting the hoist through an adjustment oil cylinder; when the hoist When working, the frame can be driven by the adjustment cylinder, and the deflection angle between the steel wire rope and the vertical plane of the drum shaft can be adjusted correspondingly as the wire rope winds in or out of the drum, so that the deflection angle between the steel wire rope and the vertical plane of the drum shaft can be reduced . The invention greatly reduces the wear and tear of the steel wire rope and the adjacent rope ring, prolongs the service life of the steel wire rope, and has simple structure, reasonable structure, strong load bearing and easy installation, and solves the problem that the related technology cannot fundamentally eliminate the serious problem of the hoist wire rope. The problem of wear and tear has filled the gap in this technical field. The present invention is especially suitable for hoisting machines with long-term heavy-duty operations, such as rotary drilling rigs, and is also generally applicable to any other machines using hoisting machines.

Description

technical field [0001] The invention relates to a hoisting device, in particular to a winch. Background technique [0002] Hoist is a commonly used lifting equipment for construction machinery, port machinery, hoisting machinery, drilling machinery, petroleum machinery, offshore heavy industry and other machinery. For a long time, the wear and tear problem of the steel wire rope caused by the objective deflection angle when the steel wire rope is wound on the drum has been perplexing the designers and users of hoisting machines. Especially on some construction machinery such as rotary drilling rigs that require long-term heavy-duty operations, the wire ropes are severely worn and have a short service life, which increases the user's use cost and increases the manufacturer's quality cost. Although various methods are being solved in the industry, such as improving the form and parameters of the rope groove, and selecting steel wire ropes with higher tensile strength, etc., t...

For a long time, the wear and tear problem of the steel wire rope caused by the objective deflection angle when the steel wire rope is wound on the drum has always troubled the designers and users of the hoist

Especially on some construction machinery such as rotary drilling rigs that require long-term heavy-duty operations, the wire rope is severely worn and has a short service life, which increases the user's use cost and increases the quality cost of the manufacturer.

Although various methods are being solved in the industry, such as improving the form and parameters of the rope groove, and selecting steel wire ropes with higher tensile strength, etc., the results have been minimal
