A double-drum motorized winch winch

Abstract

The invention discloses a winch of a double-winding drum mechanical winching machine. The winch comprises a winch, a driving shaft, a spline, shape holes, steel wire ropes, a winch frame, a winch cover plate, double winding drums, taper grooves and winching patterns, wherein a double-winching drum winch is arranged between the winch frame and a winch end cover; the winch is connected with the winch frame through the driving shaft; the spline and multiple shape holes are arranged on the winch; multiple taper grooves are peripherally arranged on the winch; the winching patterns are transversely arranged on the inner surface of the taper grooves; the steel wire ropes are wound in the taper grooves, and are alternately wound on the winch; the winch frame is assembled on the winching machine; and the winching machine controls the double winding drums to operate. The taper grooves and the full-distributed winching patterns are adopted to solve the problems of contact area and friction force between the winch and the steel wire ropes; the double-winding drum winch is high in traction efficiency; the friction force between the steel wire ropes and the winch is great without easily causing slip to reduce the damage of the steel wire ropes; and the winch is high in safety coefficient, low in labor intensity and suitable for the steel wire ropes with various specifications.

Description

technical field [0001] The invention relates to the field of double-drum traction technology equipment, in particular to a winch of a double-drum motorized winch. Background technique [0002] Dual drum pulling winches are known in the art. They typically include a frame supporting a first rotatable drum and a second rotatable drum to enable the wire rope to be wound on both drums, and further include a frame for rotating the two drums about their respective axes of rotation. one or more drives. The circumferential surface of each drum is provided with parallel circumferential grooves extending perpendicularly to the axis of rotation of the drums for engaging, in use, the wire rope wound on the two drums. [0003] The tension in the wire rope wound on the two drums, more particularly the tension in the wire rope carried by the grooves provided in the outer surface of each drum, increases as the wire rope moves from the lower tension end of the drum towards the drum. The h...

Problems solved by technology

[0004] The problem with known traction winches is that the wire rope wears out quickly, under load the wire rope stretches and causes the wire rope to slide; the stretching of the wire rope and the sliding of the wire rope along the surface of the drum leads to slight deformations, in the prior art when using double coils When the barrel winch mill is working, the wire rope is very easy to be damaged. The main reason is that there is not enough friction between the wire rope and the winch, and there is slipping and wear. On the one hand, it is easy to damage the wire rope and cause unnecessary waste; Cause safety hazards, it is imperative to develop a new type of grooved winch
