Embodiment Construction

[0014] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0015] The structure diagram of the double-motor elevator traction system of the present invention is as follows: figure 1 As shown, it includes two traction machines at the top and bottom of the hoistway, upper traction sheave 1, lower traction sheave 2, traction rope, car 3, counterweight 4, guide wheel A5, reverse rope pulley A8, reverse rope Sheave B9, car rope head plate 11, and detection and control system 12 for detecting the operation of the elevator. The two traction machines are connected to the counterweight 4 through the traction rope and the guide wheel A5. The other end of the counterweight 4 is connected to the lower traction machine. The traction sheave 2 is connected, the counterweight 4 is located behind the car 3, and the upper end of the car 3 is fixed on the car rope head plate 11, and the traction sheave 1 is connected through the reverse sheave A8 and t...

Abstract

The invention relates to a dual-motor elevator traction system, which comprises two traction machines which are arranged on the top and the bottom of a well, an upper traction wheel, a lower traction wheel, a hoist rope, a car, a counterpoise, a guide wheel A, a diversion sheave A, a diversion sheave B, a car rope hitch plate and a detection control system for detecting the operation of the elevator, wherein the two traction machines are connected with the counterpoise by the hoist rope and the guide wheel A; the other end of the counterpoise is connected with the lower traction wheel; the counterpoise is arranged on the rear side of the car; one end above the car is fixed on the car hitch plate, and connected with the upper traction wheel by the diversion sheave A and the diversion sheave B, and the lower end of the car is connected with the lower traction wheel to integrally form a ring-shaped structure. The dual-motor elevator traction structure disclosed by the invention improves the reliability of elevator operation.

Description

technical field [0001] The invention relates to a drive device for an elevator without a machine room, in particular to a double-motor elevator traction system and a control method for realizing redundant control of the double-motor traction system. Background technique [0002] The machine room-less elevator is an elevator model developed to save the layout space of the elevator machine room according to market needs. The machine-room-less elevator is not only compact in structure, saves space, but also energy-saving and efficient. There are usually two arrangements for the traction mechanism of machine room-less elevators: one is that the traction machine is located at the bottom of the hoistway, referred to as the lower traction; the other is that the traction machine is located at the top of the hoistway, referred to as the upper traction. [0003] In the modern elevator control system, how to improve the reliability of the elevator, that is, to ensure that the system ca...
