Large-diameter steel wire rope feeding device

Abstract

The invention provides a large-diameter steel wire rope feeding device, and belongs to the technical field of hoisting machinery manufacturing. The large-diameter steel wire rope feeding device comprises hydraulic motors, wherein the hydraulic motors drive a cable holding winding drum to rotate. A pilot overflow valve and a first manually-controlled reversing valve are arranged between the hydraulic motors and a hydraulic pump in sequence. A one-way sequence valve is arranged between an oil inlet of the pilot overflow valve and the first manually-controlled reversing valve, and the control end of the one-way sequence valve is connected with an oil outlet of the pilot overflow valve. The control end of the pilot overflow valve is connected between the one-way sequence valve and the first manually-controlled reversing valve and connected with an oil port formed in one end of a second manually-controlled reversing valve, and an oil port formed in the other end of the second manually-controlled reversing valve is connected between the first manually-controlled reversing valve and an oil tank. An overlaying type overflow valve is arranged between the second manually-controlled reversing valve and the oil tank. The large-diameter steel wire rope feeding device can solve the problem that when ropes of a winch are fed, the tension generated by the steel wire ropes cannot be constant.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery manufacturing, in particular to a large-diameter wire rope loading device for a winch. Background technique [0002] The wire rope winding device is a device for winding the winch drum. The existing wire rope winding device includes a motor-driven cable holding drum for winding the winch drum. Because the wire rope winding device is driven by a motor, its cable holding drum and winch When the rope is put on between the drums, the rotation of the motor makes it difficult to control the tension generated by the direct pull between the two, especially as the diameter of the wire rope increases, the tension of the wire rope going up to the cable drum also increases, resulting in The tension force of the winch cannot be constant, which causes the winch to loosen and sometimes tighten the ropes. Not only the arrangement of the wire ropes on the winch drum is not neat, the ropes are pressed an...
