Online traction steel wire rope tensioning force unevenness detection device and work method thereof

Abstract

The invention relates to an online traction steel wire rope tensioning force unevenness detection device. A traction elevator steel wire rope head spring adjusting assembly, a steel wire rope connecting assembly, a displacement monitoring assembly and a U-shaped installing frame are included. An opening of the U-shaped installing frame is arranged rightwards, an n-shaped installing frame is arranged at the bottom of the U-shaped installing frame, a first through hole is formed in the top of the n-shaped installing frame, and a long-strip-shaped second through hole is formed in the right side edge of the installing frame. The rope head spring adjusting assembly is arranged in the first through hole. The traction steel wire rope head spring adjusting assembly comprises a rope head spring anda rope head screw. The situation that an elevator is additionally forced to be stopped at the static state is avoided, normal running of the elevator is not influenced, real-time monitoring of the traction elevator steel wire rope tension changes can be achieved, convenience is high, and efficiency is high.

Description

technical field [0001] The invention relates to the technical field of elevator safety, in particular to an on-line detection device for uneven tension force of a traction steel wire rope and a working method thereof. technical background [0002] The tension deviation of the elevator traction wire rope not only has a great influence on the life of the traction sheave and the wire rope, but also has a great influence on the stability and comfort of the elevator. Therefore, it is very important to monitor the tension of the elevator wire rope in real time. The "Elevator Supervision and Inspection Regulations" promulgated by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China stipulates that "the deviation between the tension of the traction rope and the average value is not greater than 5%". The force gauge measures the tension of each wire rope and calculates the tension deviation value". In practical applications,...

Problems solved by technology

In practical applications, the common practice is to use the spring balance to radially pull the steel wire rope to the same reference point and then look at its stress to judge the uniformity of the tension of the traction rope. Obviously, this method has poor accuracy and is greatly influenced by human factors.
