A non-traction inclined elevator and its control method

Abstract

The invention relates to a non-traction type inclined elevator and a control method thereof. The inclined elevator comprises an inclined track, a support system, a driving system, a control system, weight sensors, a pedal, guiders and an inclined supporting pier. The driving system comprises two pairs of same stators and rotors. The stators are laid along the inclined track and fixed with the inclined track. The rotors are located below the stators and fixed with a support frame. The control system comprises following steps: controlling the exciting current of rotor windings through the difference between given values of resultant force and actual values detected by the weight sensors and by given values of exciting current of the rotor windings outputted by a PI regulator such that closed-loop control of resultant force is realized, wherein the resultant force is vertical to the direction of the inclined track; and obtaining given values of traction force through given speed, the acceleration curve and loads detected in real terms such that input current of the stator windings is controlled and closed-loop control is achieved over elevator speed, and the accelerated speed. The non-traction type inclined elevator and the control method thereof have following beneficial effects: there is no need to use a traction machine or a traction rope; control is easy; operation is safe; power consumption is little; and installation and maintenance are easy and convenient.

Description

technical field [0001] The invention relates to an elevator, in particular to a non-traction inclined elevator that can run on stairs, accommodation ladders and slopes, and belongs to the field of elevators. Background technique [0002] As a barrier-free facility, oblique elevators are mainly used in public places such as corridors, stations, airports, ships, and underground passages without vertical elevators. They are used to transport people or luggage and other goods, bringing convenience to people. [0003] Existing inclined elevators are generally traction type, and the main components are traction machine and traction wire rope. the goal of. In the prior art, the structure of the oblique elevator is relatively complicated, not only the production cost is high, but also the installation and maintenance are inconvenient, the failure rate is high, and the energy consumption is large. Contents of the invention [0004] The main purpose of the present invention is to ...
