Problems solved by technology

Since the material cost of the inclusion is generally higher than that of the steel wire rope, the manufacturing cost of the entire tension member is also relatively high, which increases the cost of the elevator system

Embodiment 1

[0018] Such as figure 1 and figure 2 As shown, the elevator device of the present invention includes a hoistway 1, a car 2 that moves up and down in the hoistway 1, a counterweight 3, and a driving device 4 that drives the pulley 5 and makes the car 2 go up and down. The driving device 4 is arranged on the top of the lifting passage 1 and is fixed on the mounting base 11, and the mounting base 11 is fixed on the car guide rail 9 and the counterweight guide rail 10. The guide wheel 7 is installed on the top of the elevator passage 1 by the mounting seat 8, which is approximately in the center of the car 2, and the installation seat 8 is fixed on the top of the elevator passage 1. The flat rope 6 is in contact with the drive pulley 5, and one end extends downward from the drive pulley 5 to the counterweight 3, and the other end extends downward to the car 2 through the guide pulley 7, forming a 1:1 elevator traction system. It can be seen from the diagram that the elevator de...

Embodiment 2

[0025] Such as image 3 shown. The difference from Embodiment 1 is that the driving device 4 and the driving pulley 5 are arranged in the machine room 14 , and the installation seat 11 , the guide wheel 7 and the installation seat 8 are also arranged in the machine room 14 .

Abstract

The invention discloses an elevator device. The elevator device comprises a lifting passage, a cage and a balance weight lifting in the lifting passage, a driving device which is provided with a driving pulley and lifts the cage and at least one flat rope coiled and hung among the driving pulley, the cage and the balance weight; the flat rope comprises at least one bearing body and a wrapping body; the wrapping body is made of a nonmetal material; the bearing body consists of a plurality of bearing core wires; at least one part of the bearing body is embedded into the wrapping body; the wrapping body is contacted with the driving pulley; the ratio of the width dimension of the flat rope to the thickness dimension is more than or equal to 1; the flat rope is connected with the cage and thebalance weight; and the elevator device is a system with a one-to-one winding method. The elevator device has the characteristics that the elevator device has a simple structure, easy mounting, smallvibration and noise and low cost, is favorable for distinguishing the rupture condition of the flat rope through appearance, ensures the safety of the elevator system, improves the repairing and maintenance efficiency of the elevator system and the like.

Description

technical field [0001] The present invention relates to an elevator installation. Background technique [0002] In the elevator device driven by the traditional traction pulley, the stressed member is a steel wire rope. There are certain restrictions on the use of wire ropes, such as the limitation of the traction force between the wire rope and the traction pulley, the requirements on the bending performance and fatigue performance of the wire rope. Due to the limitation of traction, in order to increase the traction, it is often necessary to increase the wrap angle between the wire rope and the traction pulley, or slot the traction pulley, which will reduce the life of the wire rope. At the same time, due to the requirements of the bending performance and fatigue performance of the wire rope, the minimum diameter of the wire rope is 8mm (GB7588-2003 standard), and the diameter of the traction pulley is at least 40 times the diameter of the wire rope. Therefore, the minim...
