Problems solved by technology

This will also significantly increase the cost of the elevator installation
Moreover, since it is difficult to reinforce the bottom of the hoistway on the existing elevator device, it is difficult to add this kind of buffer mechanism to the existing elevator device.

[0026] figure 1 This is a schematic diagram schematically showing the first embodiment of the elevator apparatus of the present invention. figure 1 The illustrated elevator apparatus 100 includes a hoistway 102, a machine room 104, a car 106, a counterweight 108, a traction machine 110, a compensation device 120, and a speed governor. A machine room 104 is provided above the hoistway 102 . The machine room 104 is provided with a traction machine 110 and a speed governor body 140 . The car 106 and the counterweight 108 are connected by a hoisting rope 114 , and the hoisting rope 114 is wound on the hoisting sheave 112 of the hoisting machine 110 . The car 106 and the counterweight 108 are driven up and down by the hoistway 102 under the driving of the hoisting machine 110 .

[0027]The speed limiter includes a speed limiter body 140 , a speed limiter rope 142 and a speed limiter tensioning pulley 144 . The speed limiter body 140 is provided with a speed limiter sheave. T...

no. 2 Embodiment ＞

[0036] Figure 5 A schematic diagram of the compensation device 520 of the second embodiment of the elevator apparatus of the present invention is briefly shown. This embodiment is a modification of the first embodiment. In the present embodiment, the same reference numerals are given to those components that are the same as, corresponding to or equivalent to those of the first embodiment, and the description of these components will be omitted or simplified. The biggest difference between the compensation device 520 of this embodiment and the compensation device 120 of the first embodiment is that a spring 522 is provided between the first flexible rope 129 and the first additional vertical weight 128 .

[0037] like Figure 5 As shown, a connecting plate 524 is provided between the first flexible rope 129 and the spring 522 in order to facilitate the installation of the spring 522 and to make the force direction of the spring 522 parallel to its axial direction. The sprin...

[0044] Figure 8 This is a schematic diagram schematically showing a third embodiment of the elevator apparatus of the present invention. This embodiment is a modification of the second embodiment. In the present embodiment, the same reference numerals are given to those components which are the same as, corresponding to or equivalent to those of the second embodiment, and the description of these parts will be omitted or simplified. The biggest difference between the elevator apparatus 800 of the present embodiment and the second embodiment is that the second additional vertical weight 828 is provided. The second additional vertical weight 828 is arranged at the bottom of the hoistway 103 below the second tensioning vertical weight 146 . Vertical guide rails are provided on both sides of the second additional vertical weight 828, and the second additional vertical weight 828 can move up and down along the vertical weight guide rail.

Abstract

The invention relates to an elevator device. The elevator device comprises a car (106), a counterweight (108), a tractor (110) and a compensating device (120), wherein the compensating device comprises a first tensioning perpendicular weight (126) which is suspended on a rotary shaft (124a) of a compensating rope tensioning wheel (124), a first additional perpendicular weight (128) which is arranged at a shaft bottom (103) below the first tensioning perpendicular weight and is provided with a through hole (128a) in the middle part for allowing the first tensioning perpendicular weight to pass through, and a first flexible rope (129) which connects the first tensioning perpendicular weight to the first additional perpendicular weight. Generally, the first flexible rope is in a relaxed state, so that gravity of the first additional perpendicular weight does not act on the compensating rope tensioning wheel. When the compensating rope tensioning wheel upwards jumps, the first tensioning perpendicular weight which jumps along with the compensating rope tensioning wheel pulls the first additional perpendicular weight through the first flexible rope, so that gravity of the first additional perpendicular weight acts on the compensating rope tensioning wheel, and therefore, jump of the compensating rope tensioning wheel is restrained.

Description

technical field [0001] The present invention relates to an elevator apparatus. Background technique [0002] The traction elevator device uses the friction force between the traction rope located in the traction sheave groove and the traction sheave groove to drive the car and the counterweight connected to both ends of the traction rope to run up and down. When the elevator is running, the lengths of the hoisting ropes on the car side and the counterweight side are constantly changing. For long-travel elevators in high-rise buildings, the length and weight of the hoisting ropes are large. Therefore, according to the position of the car and the counterweight, when the traction rope on one side of the traction sheave is much longer than the other side, the load on both sides of the traction sheave will cause a serious imbalance, making it difficult for the elevator to achieve stable operation. In order to reduce the load difference on both sides of the traction sheave durin...
