Embodiment Construction

[0008] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0009] The preferred mode of realizing the present invention is:

[0010] A driving device for an elevator. The elevator is provided with a machine room at the bottom 1 of the car. The driving method of the elevator is a permanent magnet synchronous motor 8 equipped with an external block brake 7 to control the rack and pinion mechanism through a worm gear reducer 6, wherein The rack and pinion mechanism is two pairs of helical gear and helical rack mechanisms that are installed around the car shaft, including: the helical gears of the two pairs of helical gear shaft members 2 are respectively connected with two pairs of vertically installed helical racks 5. The intermediate gear member 3 meshes with the driving gea...

Abstract

The invention discloses an elevator driving device, in particular the technical field of driving devices of lifting machinery. Most driving devices of passenger and cargo elevators used by traditional high-rise buildings are steel wire rope-dragged elevators, so that the safety is low, the operation is unreliable, and such serious accidents as elevator falling, roof dashing, passenger clamping and empty stepping happen occasionally; and the elevator safety and the operation reliability are the technical problems to be solved by the invention. For this purpose, the invention adopts the technical scheme of arranging a machine room in the bottom of a car, mounting a variable-speed motor with a brake and controlling a gear-rack mechanism through a worm-gear speed reducer, so that an elevator is prevented from serious accidents of falling to bottom and roof dashing, and the elevator operation safety and reliability are obviously improved.

Description

(1) Technical field [0001] The invention relates to a drive device for an elevator, in particular to the technical field of a drive device for lifting machinery. (2) Technical background [0002] At present, the driving devices of the elevators used in high-rise buildings are mostly wire rope traction driving devices, and their safety is not high. Serious accidents such as elevator falling, rushing to the top, pinching people and stepping into the air often occur. (3) Contents of the invention [0003] The invention relates to a driving device of an elevator, and the technical problem to be solved is the safety and reliable operation of the elevator. For this reason, the present invention adopts following technical scheme, a kind of driving device of elevator, and this elevator is provided with machine room at the bottom of car, and the driving mode of elevator is that the variable-speed motor with brake is installed to control pinion and rack mechanism through worm gear r...
