Abstract

The invention provides a machine-room-less built-in lead screw elevator. The machine-room-less built-in lead screw elevator comprises an elevator well, an elevator car, a steel wire rope, a rope guiding wheel assembly and a driving device, wherein the elevator car, the steel wire rope, the rope guiding wheel assembly and the driving device are contained inside the elevator well. The elevator well comprises a bearing beam and a base, the bearing beam is arranged at the top of the elevator well, the rope guiding wheel assembly is fixedly arranged on the bearing beam, and the base is arranged at the bottom of the elevator well; the driving device comprises a motor, a counterweight housing and a first unthreaded rod, a lead screw and a second unthreaded rod, wherein the first unthreaded rod and the second unthreaded rod are connected in sequence in the vertical direction, the upper end of the first unthreaded rod is fixedly arranged on the bearing beam, the lower end of the second unthreaded rod is fixedly arranged on the base, the motor is arranged on the counterweight housing, and the counterweight housing is arranged on the lead screw. According to the machine-room-less built-in lead screw elevator, the advantages of a machine-room-less elevator and a lead screw elevator are synthesized, and the machine-room-less built-in lead screw elevator has the advantages of being high in transmission efficiency, high in safety, stable in operation and the like.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a machine-room-less built-in lead screw elevator. Background technique [0002] In modern society, the use of elevators is very extensive, it can be said that it is inseparable from people's daily life, and has become a ubiquitous device for transporting people and goods in multi-storey buildings. In order to overcome many limitations of buildings, save resources and reduce costs, machine room-less elevators are widely used now. In existing machine-room-less elevators, the traction machine is generally installed on the load-bearing beam at the top of the elevator shaft, and a protective fence is installed on the top of the elevator car. The elevator car can be used as a maintenance platform for maintenance and the available space is effectively utilized. [0003] Existing elevators generally use steel cables for lifting and lowering, so they have the characteristics of easy br...
