Problems solved by technology

[0003] However, during the on-site installation of the elevator, there is often a certain amount of deviation in the height of the shaft. At the same time, the installation of compensation cables of different specifications has corresponding restrictions on the height of the flat cable from the ground and the bending radius. Therefore, the installation process of the compensation cable The adjustment of its length and the adjustment of the bending radius must be considered

Embodiment 1

[0042] Such as figure 1 As shown, it is the overall layout of the elevator after the device of the present invention is applied, which includes the car bottom 7, the safety gear frame 8, the car bottom rear beam 9, the compensation cable termination device 10, the counterweight 11, the buffer 12 and the flat compensation cable 3 . Wherein the termination device 10 of the present invention is installed under the car floor, and its two ends are respectively connected and fixed with the safety gear frame 8 and the car floor rear beam 9 . One end of the flat cable 3 is connected under the counterweight, and the other end is connected to the termination device 10 of the present invention.

[0043] Such as figure 2 As shown, it is a structural top view of the adjustable elevator balance compensation cable termination device according to the present invention, which mainly includes the following components:

[0044] The mounting arm 1, the two ends of which are respectively fixed...

Embodiment 2

[0053] Such as Figure 4 As shown, compared with Embodiment 1, this embodiment considers the change of the structure form of safety gear frame 8, and the form and installation direction of mounting seat 2 have been adjusted. The winding direction is changed from horizontal to vertical, which is more convenient for on-site operation.

[0054] Specifically, combined with Figure 5 , Figure 6 As shown, the fixing seat 14 is mainly composed of a round tube and a support member, and is fixed on the mounting arm 1 by a bolt assembly 13. The adjustment method of the length and bending radius of the flat cable is the same as that of the first embodiment.

[0055] Compared with Embodiment 1, the structure arrangement in Embodiment 2 is more compact, and the space utilization rate is higher. At the same time, the flat cable wire rope head 31 is fixed toward the upper part, and the on-site operation is more convenient.

Embodiment 3

[0057] The device of the present invention described in Embodiments 1 and 2 is arranged on the premise that the center of the car coincides with the center of the counterweight, that is, the left and right flat cables are arranged symmetrically. When the counterweight eccentricity occurs in the actual wellway civil construction, the installation position of the mounting seat 2 should be adjustable to adapt to the eccentricity of the car and the counterweight center. Such as Figure 7 , Figure 8As shown, in this embodiment, the counterweight is eccentric to the right and the counterweight is eccentric to the left respectively. At this time, the mounting seats 2 on the left and right sides should be installed towards the eccentric side of the counterweight at the same time.

[0058] In this embodiment, the mounting beam 15 is a "ㄇ"-shaped bending part, and the left and right end faces of the mounting beam 15 can realize the mounting and fixing of the mounting base 2 . At the ...

Abstract

The invention discloses an adjustable balance compensation cable terminating device for an elevator. The adjustable balance compensation cable terminating device for the elevator comprises a mountingarm, a mounting seat and a supporting arm, wherein the mounting arm is fixedly connected to the lower part of the bottom of an elevator car; the mounting seat is adjustably connected to one end of themounting arm; the mounting seat is used for winding a steel wire rope at the end part of a flat compensation cable and fixing a rope head; and the supporting arm is adjustably connected to the otherend of the mounting arm, and is used for supporting the flat compensation cable. According to the adjustable balance compensation cable terminating device for the elevator provided by the invention, on the premise that the structural strength is guaranteed, the adjustment convenience of the length and the bending radius of the flat cable is improved.

Description

technical field [0001] The invention relates to the field of elevators, in particular to an adjustable balance compensation cable termination device for elevators. Background technique [0002] At present, in order to reduce the power of the main engine and improve the comfort of the elevator, the traction elevator is usually equipped with a compensation system to compensate for the weight difference between the car and the steel wire rope on both sides of the counterweight. According to the different running speeds of the elevator, the compensation system usually adopts three forms: compensation chain, compensation cable and compensation rope. Among them, when the rated running speed of the elevator is within the range of 2.0-3.0m / s, the compensation cable is usually configured. [0003] However, during the on-site installation of the elevator, there is often a certain amount of deviation in the height of the shaft. At the same time, the installation of compensation cables...
