Apparatus for equalizing the tensions among elevator wire ropes

Abstract

The present invention relates to an apparatus for equalizing tensions among elevator wire ropes, which immediately eliminates imbalance and equalizes the tensions among elevator wire ropes in the event of differences in the lengths of elevator wire ropes, to thereby improve safety, durability and reliability. The apparatus of the present invention automatically corrects imbalance caused by changes in the lengths of a plurality of elevator wire ropes (700) to maintain a balance in the tensions of elevator wire ropes, and comprises: a main body (200f), the interior of which has an accommodation space; tension adjustment means coupled to a plurality of belts (10f, 20f, 30f, 40f) connected to the elevator wire ropes (700), respectively, and arranged in the main body (200f); a main rotary shaft (50f) which penetrates through the tension adjustment means and which is rotatably coupled to the main body (200f); and first and second external gears (45f, 48f) which are fixed at the main rotary shaft (50f) such that the gears (45f, 48f) are rotatable, and which are coupled to the front and rear surfaces of the tension adjustment means to transmit rotating forces.

Description

technical field [0001] The present invention relates to an elevator wire rope tension equalization device, and more specifically relates to an elevator wire rope tension equalization device in which a plurality of wire ropes suspended by a plurality of wire ropes are suspended due to bending and unwinding etc. The mechanical movement of the reciprocating motion deforms the length of each wire rope, and when a length difference occurs, the fluctuating length can be immediately corrected. Background technique [0002] Usually, in the process of reciprocatingly transporting the elevator car by means of the suspended individual wire ropes, an imbalance of tension among the individual wire ropes occurs. [0003] At present, this imbalance of tension is managed periodically, but even with such periodic inspection and management, since the change occurs in real time with the temperature of the site where the elevator is installed and the number of times the elevator is operated, th...

Problems solved by technology

[0007] The present invention is proposed to solve the above-mentioned problems of the prior art, and its object is to provide a device for equalizing the tension of elevator steel wire ropes as follows. The difference in the length of the wire ropes causes an imbalance in the force received by multiple wire ropes from one load, resulting in uneven tension between the wire ropes. In order to immediately eliminate this imbalance, the tension can be made uniform
