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

Screw-threaded shaft elevator
Technical field
The present invention relates to screw-threaded shaft elevator field.
Background technology
In modern society, the utilization of elevator is very extensive, daily life of can mediating a settlement interwoveness, has become for conveying people among multi-story structure and the ubiquitous equipment of goods.
General elevator employing capstan winch is proposed rope drive and is taken advantage of case to run, but because an escalator only can configure one and take advantage of case, therefore cause and use building area comparatively large, degree of utilization is not high, but also will configure the corresponding interior space for rope; In addition, rope is also potential the danger got loose, and rope shake causes and takes advantage of case to shake.
By adopting screw-threaded shaft elevator, above-mentioned subproblem can be eliminated, but leading screw is connected with described motor by gear system, there is special area equally excessive, inconvenient maintenance, and there is potential safety hazard.
Summary of the invention
For the technical matters that in prior art, screw-threaded shaft elevator volume is large, installation and maintenance are difficult, the invention provides and a kind of simple, the little peace of volume, screw-threaded shaft elevator that overall coefficient is high are installed.
Screw-threaded shaft elevator, comprise crane and jacking system, described jacking system comprises motor and leading screw, described motor comprises outer rotor and internal rotor, and described crane one end is connected with described outer rotor, and described internal rotor comprises a through hole, screw thread is provided with in described through hole, described leading screw outer wall is provided with screw thread, and described leading screw is arranged in described through hole, passes through screw-threaded engagement with described motor internal rotor.
In a preferred embodiment of the present invention, described machine operation can drive described internal rotor to rotate, and described crane is moved reciprocatingly along described leading screw setting direction.
In a preferred embodiment of the present invention, described jacking system also comprises band-type brake, and described band-type brake is arranged on described motor bottom.
In a preferred embodiment of the present invention, described jacking system also comprises rotary encoder, and described rotary encoder is arranged on bottom described band-type brake.
In a preferred embodiment of the present invention, described band-type brake and rotary encoder include a through hole, and described leading screw runs through described through hole.
In a preferred embodiment of the present invention, when described motor quits work, the fastening locked described leading screw of described band-type brake through hole.
In a preferred embodiment of the present invention, described screw-threaded shaft elevator also comprises controller, and described controller is electrically connected with described rotary encoder, and described controller controls operating rate and the mode of operation of described motor by described rotary encoder.
In a preferred embodiment of the present invention, described motor is magneto-electric machine.
Compared to prior art, leading screw is set directly at described motor internal by screw-threaded shaft elevator of the present invention, and engages with described motor internal rotor, makes full use of building area, saves careat, and eliminates the corresponding interior space of configuration rope.Further, leading screw is relied on to run with the engagement of motor, absolutely not the possibility that drops of crane; Also just because of rely on leading screw to run with motor engagement, rope shake can be exempted and cause and take advantage of case to shake.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
