Embodiment Construction

[0029] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0030] refer to figure 1 , a screw-type vertical elevator, including a shaft a, a car 1 and a driving mechanism 2 for vertically lifting the car 1 in the shaft a. The driving mechanism 2 includes a motor 21 , a transmission rod 22 and a plurality of screws 23 . Wherein a plurality of screw rods 23 are vertically arranged around the car 1, and the upper and lower ends of each screw rod 23 are rotatably arranged at the upper and lower ends of the hoistway a. Each screw rod 23 is sleeved with a nut 24 , and the nut 24 is connected to the car 1 through the first connecting piece 3 . Each screw 23 is provided with a second gear 231, the output shaft of the motor 21 is provided with a worm 211, the upper end of the transmission rod 22 is provided with a worm wheel 221 meshed with the worm 211, and the lower end is provided with the second gear 231 of each scr...

Abstract

The invention discloses a screw-type vertical elevator and a working method thereof, and relates to the technical field of transportation. The screw-type vertical elevator comprises a well, a lift carand a driving mechanism. The driving mechanism comprises a motor, a transmission rod and a plurality of screws. The multiple screws are vertically arranged on the periphery of the lift car, and eachscrew is provided with a nut in a sleeved mode. The nuts are connected to the lift car through first connecting pieces, and each screw is provided with a second gear. An output shaft of the motor is provided with a worm, a worm wheel engaged with the worm is arranged at the upper end of the transmission rod, and 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 lift car lifting action is achieved in a spiral transmission mode of the screws and the nuts, the certain self-locking function is achieved, labor is saved, and the falling accident is prevented from being caused on the lift car; the driving mechanism has the self-locking function through design of the worm and theworm wheel, and controllability and safety of the screw-type vertical elevator are ensured; and through design of the second gears and the first gear, synchronous rotation of the four screws can be ensured, and thus ascending and descending of the lift car are more stable.

Description

technical field [0001] The invention relates to the field of transportation machinery, in particular to a screw type vertical elevator and its working method. 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:...
