Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0019] Existing traction system mainly is made up of traction machine, traction wire rope, guide wheel, anti-rope pulley. Therefore, the existing traction system relies on the traction force of the wire rope to control the lifting, acceleration and deceleration of the car body, and there will be an obvious sense of weightlessness during starting and docking.

[0020] In order to solve the above-mentioned problems, the present invention provides a lift control metho...

Abstract

The invention provides a lifting control method. The lifting control method includes steps of setting first electromagnetic windings on the outer sides of three closed side walls; setting second electromagnetic windings on each-floor side wall of an elevator shaft at the positions relative to the first electromagnetic windings; setting a position sensor on each-floor wall of the elevator shaft; connecting the position sensors through a controller, receiving position signals of an elevator car, and outputting control signals to a tractor, the first electromagnetic windings and the second electromagnetic windings.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a lifting control method. Background technique [0002] With the intensification of the urbanization process, more and more high-rise office buildings and residential buildings are erected. During the construction process, lifting devices are needed to transport workers to the construction floors. After construction, elevators are needed to send residents to each household. Elevators It is also a kind of lifting device. Therefore, the lifting device is an indispensable means of transportation in the city, which is directly related to the quality of people's life and work. [0003] The lifting device relies on the traction system to output and transmit power. The existing traction system is mainly composed of a traction machine, a traction wire rope, a guide wheel, and a reverse rope wheel. Therefore, the existing traction system relies on the traction force of the steel wire rope to con...
