Problems solved by technology

At present, when installing the steel wires, due to the limitation of the installation space, it can only be installed manually, which is easy to cause uneven strength, and the tension of each steel wire is inconsistent, causing uneven force on the car, which will cause fluctuations during the operation of the elevator and affect the operation. The stability of the elevator has potential safety hazards

Abstract

The invention discloses a steel wire tensile force equalizer for a lift car and multi-group steel wire tensile force equalizer devices can produce the same tensile force. Each group of a steel wire tensile force equalizer device comprises a first single direction thrust ball bearing(1), a second single direction thrust ball bearing(2), a nut sleeve(3), a connector(4), an adapter sleeve(5) and a straight line telescoping mechanism provided with a telescopic link(6), wherein one end of the telescopic link(6) is connected with an end of the connector(4), the telescopic link(6) is arranged in the adapter sleeve(5), a threaded hole is formed in the other end of the connector(4), a through-hole(3.1) is formed in the nut sleeve(3), a plurality of radial direction through-hole(3.2) are arranged on the nut sleeve(3). The steel wire tensile force equalizer for the lift car enables tensile force of every steel wire to be the same so that the lift car is stressed evenly, guarantees the operational stability of the lift car and eliminates the potential safety hazard of the lift.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a steel wire tension equalizer for elevator cars. Background technique [0002] Steel wire needs to be installed when elevator car is installed, and the bolt of fixed steel wire is fixed on mounting plate, and promptly bolt passes the through hole on mounting plate again after connecting head and then tightens and fixes with nut again. The elevator car is generally connected by multiple steel wires, the most commonly used is six. After installation, the tension of all steel wires must be the same. At present, when installing steel wires, due to the limitation of installation space, it can only be installed manually, which is easy to cause uneven strength, inconsistent tension of each steel wire, uneven force on the car, and fluctuations during the operation of the elevator, affecting the operation The stability of the elevator makes the elevator a potential safety hazard.
