Abstract

The invention discloses a screw-type vertical elevator, which relates to the field of transportation machinery and includes a shaft, a car and a driving mechanism. The driving mechanism includes a motor, a transmission rod and a plurality of screws, and the plurality of screws are vertically arranged around the car. Each screw sleeve is provided with a nut, the nut is connected to the car through the first connecting piece, each screw is provided with a second gear, the output shaft of the motor is provided with a worm, the upper end of the transmission rod is provided with a worm gear meshed with the worm, A first gear meshing with each second gear is provided. Beneficial effects of the present invention: use the helical transmission mode of the screw rod and the nut to realize the lifting action of the car, have a certain self-locking function and save labor, and can prevent the car from falling. The design of the worm and worm gear makes the driving mechanism have a self-locking function to ensure the controllability and safety of the equipment. The design of the second gear and the first gear can ensure the synchronous rotation of the four screws, making the lift of the car more stable.

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...
