Abstract

The invention provides a lead screw lifter. The lead screw lifter comprises a lifting scaffold and a lifting device, wherein the lifting device comprises a motor and a lead screw, the motor comprises an outer rotor and inner rotor, one end of the lifting scaffold is connected with the outer rotor, the inner rotor comprises a through hole, threads are arranged in the through hole, threads are arranged on the outer wall of the lead screw, and the lead screw is arranged in the through hole and is meshed with the inner rotor of the motor through the threads. Compared with the prior art, the lead screw lifter has the advantages that due to the fact that the lead screw is directly arranged inside the motor and is meshed with the inner rotor of the motor, building space is fully utilized, indoor space is saved, and the indoor space for arranging a rope is not needed; furthermore, due to the fact that operation is conducted through meshing between the lead screw and the motor, the lifting scaffold can never fall off, and vibration of a lift car caused by rope shaking can be avoided.

Description

Technical field [0001] The invention relates to the field of screw elevators. Background technique [0002] In modern society, elevators are widely used and can be said to be inseparable from people's daily lives. They have become ubiquitous equipment used to transport people and goods in multi-storey buildings. [0003] General elevators use winches to lift the ropes to drive the cabins, but because an elevator room can only be equipped with one cabin, the building area is large, the utilization rate is not high, and the ropes must be equipped with corresponding indoor space; In addition, there is a potential risk of loosening of the ropes, and the shaking of the ropes can cause vibration of the carriage. [0004] By using a screw lifter, some of the above problems can be eliminated. However, the screw is connected to the motor through a gear transmission device, and there is also an excessively large dedicated area, inconvenient maintenance, and potential safety hazards.
