Description

Lifting device

Technical Field

The present utility model relates to a lifting apparatus, and more particularly, to a lifting device.

Background

The lifting device is a mechanical device for carrying people or goods on a vertical channel to lift and lower, and mainly consists of a motor, a wire-collecting shaft, a steel cable, a cable and other auxiliary components. Since the steel cable and the electric cable belong to two kinds of cables, the winding needs to be performed separately. Therefore, a steel cable winding part and a cable winding part are required to be arranged in the installation box of the lifting device. And in order to ensure uniformity in winding, the wire rope winding portion and the cable winding portion are generally arranged on a uniform winding shaft. When the motor drives the winding shaft to act, the steel cable and the cable can be wound simultaneously.

However, in practical applications, since the winding position of the winding shaft on the wire rope and the cable is always unchanged, this will cause the cable to pile up. The stacking positions of the cables are random, and if the stacking relative positions of the cables and the steel cable are inconsistent, winding errors between the cables are easy to cause, so that one of the two cables cannot be in a straightened state, and winding effects are affected.

In addition, the diameters of the cable and the wire rope used in different applications are not exactly the same. For example, a heavy-duty elevator for goods needs only to supply and control power to the cable, but a steel cable with a larger wire diameter needs to be used for the steel cable to satisfy the load-bearing stress. The two cables with one size are more easy to have the problem of different winding lengths in the winding process. Thus, improvements to existing lifting devices are needed.
