Description

Winding displacement mechanism

Technical Field

The utility model relates to the technical field of hoisting equipment, in particular to a winding and arranging mechanism.

Background

In the winch, the steel wire rope needs to be orderly wound on one layer of the winding drum from left to right and then wound on a second layer from right to left; however, since the drum has a certain axial length, the angle at which the wire rope is wound varies as the wire rope is wound into the rope groove of the drum from left to right in each layer. When the deflection angle is large, the steel wire rope cannot be closely wound into the rope groove of the winding drum, and winding confusion occurs at the moment. At present, a wire arranging device is generally adopted to arrange the wire rope, namely, a shaft parallel to the winding axis is added above the winding engine, the fixed pulley capable of moving axially is arranged on the shaft, the wire rope bypasses the fixed pulley and then winds on the winding drum, the fixed pulley moves from left to right along with the single-layer winding of the wire rope, the fixed pulley also moves along with the axial direction, the wire rope wound on the winding engine is always in a state without deflection angle or with smaller deflection angle, and the problem of winding confusion caused by the wire rope is prevented from being broken out of the rope groove. Sorting wire arranging devices: the current common wire arranging devices can be divided into two types: one is that the motor carries the pulley on the winding displacement device to do left and right axial movement through the lead screw, the other is that the pulley of the winding displacement device has no axial driving force, but the friction force between the shaft and the pulley is smaller, and the pulley can slide relatively more lubricationly, so that the pulley passively does left and right axial movement along with the rope when being under the tensioning force on the rope.

However, the wire arranging device is arranged outside the winch, the space occupation is large, a certain weight is provided, and the space occupation and weight increment can be caused inside a small winch mechanism which is small and light in weight.
