Problems solved by technology

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

Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with specific embodiments and accompanying drawings.

[0022] figure 1 The hoist 1 in some embodiments of the present invention is shown, and the hoist 1 is especially suitable for a hoist that works for a long time with heavy loads, such as a rotary drilling rig, and is also generally applicable to any other machine that uses a hoist. This hoist 1 comprises reel 10, frame 50 and steel wire rope 20, and the left end 51 of frame 50 is hinged on the carrier 60 of supporting hoist, and right end 52 is connected with the carrier 60 of supporting hoist by adjusting oil cylinder 40; When hoist 1 work, The frame 50 can be driven by the adjustment oil cylinder 40, and when the wire rope 20 winds in or out of the drum 10, it can be adjusted correspondingly with the deflection angle (that is, the angle of entry) of the vertical plane of the shaft of the drum 10, so that the entry angle of the wire rope...

Abstract

The invention provides a winch with an angle-adjustable winding drum axis, which comprises a winding drum, a frame and a steel wire rope. One end of the frame is hinged to a carrier supporting the winch, and the other end of the frame is connected with the carrier supporting the winch through an adjusting oil cylinder. When the winch works, a declination angle between the frame and a winding drum vertical plane can be adjusted correspondingly along with the steel wire rope coiling in and coiling out of the drum under driving of the adjusting oil cylinder, and the declination angle between the steel wire rope and the winding drum vertical plane is reduced. The winch greatly reduces abrasion between the inlet and outlet steel wire rope and an adjacent rope ring, prolongs service life of the steel wire rope, is simple and reasonable in structure, strong in bearing load and easy and convenient to install, solves the problem that relevant technology can not solve the problem of severe abrasion of the steel wire rope of the winch fundamentally, and fills a gap in the technical field. The winch is especially applicable to machines with winches for long-time heavy-load operation, such as rotary excavating drilling machines, and is also widely suitable for other machinery using winches.

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...
