Screw type vertical elevator

Abstract

The invention discloses a screw type vertical elevator, and belongs to the field of transportation machines. The screw type vertical elevator comprises a shaftway, a car and a drive mechanism. The drive mechanism comprises a motor, a transmission rod and a plurality of screws. The multiple screws are vertically arranged around the car. Each screw is sleeved with a nut. Each nut is connected to the car through a first connecting piece. Each screw is provided with a second gear. A worm is arranged on an output shaft of the motor. A worm gear engaged with the worm is arranged at the upper end of the transmission rod. A first gear engaged with all the second gears is arranged at the lower end of the transmission rod. The screw type vertical elevator has the beneficial effects that the ascending and descending actions of the car are achieved through the screw transmission manner of the screws and the nuts, a certain self-locking function is achieved, labor is saved, and the falling accident can be prevented from happening to the car. By means of the design of the worm and the worm gear, the drive mechanism has the self-locking function, and controllability and safety of equipment are guaranteed. By means of the design of the second gears and the first gear, it can be guaranteed that the four screws rotate synchronously, and the car can ascend and descend more stably.

Description

technical field [0001] The invention relates to the field of transport machinery, in particular to a screw type vertical elevator. Background technique [0002] Elevator is a kind of vertical elevator powered by electric motor, equipped with box-shaped gondola, used for multi-storey buildings to take advantage of people or carry goods. A vertical elevator has a car running between at least two vertical or inclination angles of less than 15° rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or to load and unload goods. It is customary to use elevator as a general term for vertical transportation in buildings regardless of its driving mode. Hydraulic elevators began to appear in the mid-19th century and are still used in low-rise buildings today. In 1852, E.G. Otis of the United States developed a safety elevator for wire rope lifting. The following problems still exist in the existing elevator: 1. when the elevator breaks...

AI Technical Summary

Problems solved by technology

[0003] The present invention provides a screw-type vertical elevator, aiming to solve the disadvantages of the existing elevators that there is a risk of the car falling, and when the car and the landing door are misaligned, it is easy for passengers to step on the air.
