Embodiment 1

[0040] Such as figure 1As shown in the figure, in the machine room-less 1:1 elevator device shown in the figure, in the hoistway 1, the traction machine 2 is installed on the car guide rail 7 on one side, and is connected to the side wall 1b of the hoistway through the auxiliary bracket 8 at the same time. In order to reduce the vibration to the side wall 1b of the hoistway, rubber is used to insulate between the auxiliary bracket 8 and the side wall 1b of the hoistway.

[0041] The car 3 and the counterweight 4 are connected together by a traction rope 6 and hung on the traction sheave 2a and the guide sheave 5 . The traction wrap angle between the traction rope 6 and the traction wheel 2a is realized by adjusting the traction wheel 2a and the guide wheel 5, and is controlled at 70-120°. In order to minimize the height of the top floor, the traction wrap angle is preferably at 80°~90°. In order to reduce the height of the top floor of the hoistway as far as possible, the gu...

Embodiment 2

[0052] The difference of the machine-room-less 1:1 elevator device in this embodiment is that the structure of the traction rope 6 is different, and the rest of the structures are the same.

[0053] In order to increase the breaking force of the traction rope and provide support for the independent carrier 2 of the outer layer, such as figure 2 As shown, all the independent bearing bodies in this embodiment are distributed in two concentric circles in the radial direction in the elastic body 1 constituting the traction rope body, and the independent bearing bodies of each layer are evenly distributed on the same circumference, considering the compactness of the structure , the diameter of the independent carrier 3 of the inner layer is smaller than the diameter of the independent carrier 2 of the outer layer, and every two adjacent independent carriers 3 in the independent carrier 3 of the outer layer are evenly spaced on the same circumference and constitute the traction rope...

Abstract

The invention discloses a machine-room-free elevator device. The machine-room-free elevator device comprises a traction machine, a carriage, a counterweight, at least one guide wheel, a group of traction ropes and a control cabinet, wherein the suspension ratio is 1:1, and the machine-room-free elevator device is characterized in that each traction rope consists of an elastic body forming a traction rope body and a plurality of independent carrier bodies which are arranged in the elastic body and parallel to the traction rope body. By increasing the traction friction coefficient, reducing a wrap angle and reducing the diameter of the traction wheel and the guide wheel, the height of the top layer is reduced as far as possible, so that the 1:1 elevator structure without a machine room has the practical value. In addition, the traction friction coefficient is controlled through the elastic body material on the outer layer of the traction rope, so that the wrap angle is controlled, and the height of the top layer is greatly reduced from two aspects by controlling the structure of the traction rope and controlling the diameter of the traction wheel and the guide wheel.

Description

technical field [0001] The present invention relates to an elevator device, in particular to a machine-room-less 1:1 elevator system, and more specifically to a machine-room-less 1:1 elevator device with circular traction ropes in a parallel carrier structure. Background technique [0002] The currently widely used elevator system includes a traction machine, a car and a corresponding counterweight, and more than two traction ropes suspended on the traction machine to support and drive the car and the counterweight. According to the requirements of GB7588 "Code for Elevator Installation", the calculation of traction force needs to meet the Euler formula: [0003] T 1 T 2 ≤ e f α ; [0004] Among them, T 1 ,T 2 is the tension on both sides of the traction sheave, f is the equivalent friction coefficient, and α is the traction wrap...
