The invention discloses a portable rope tension balancing instrument of a multi-rope lifting system. The portable rope tension balancing instrument comprises a cavity, a weighing sensor, a bearing component, an anti-rotating screw and an anti-rotating nut, the inside of the cavity is partitioned into an upper cavity body and a lower cavity body by a plate, the upper cavity body is provided with a top cover, an adjusting window and an anti-rotating groove in an up-down direction are formed in the side wall of the lower cavity body, the weighing sensor is mounted inside and limited and protected by the upper cavity body, and externally connected with a data display module, the bearing component is mounted below the top cover of the upper cavity body and above the weighing sensor, the upper section of the anti-rotating screw penetrates the cavity, the weighing sensor and the bearing component to be connected with an adjusting nut while the lower section of the same is connected with a rope end screw through an internal threaded hole, a guide rod is extended from the side face of the anti-rotating screw and moves up and down in the anti-rotating groove of the lower cavity body, and the anti-rotating nut is mounted on the rope end screw and closely abutted against the lower section of the anti-rotating screw. The rope tension balancing instrument is light, small and portable, has functions of measuring and adjusting and has high safety and universality, and working efficiency is effectively improved.
Description
technical field [0001] The invention relates to a device which uses a sensor to measure and adjust the tension distribution of ropes, in particular to a portable multi-rope hoisting system rope tension equalizer. Background technique [0002] During the operation of multi-rope hoisting systems such as elevators and mining machinery, it is necessary to frequently measure and adjust the tension distribution of the ropes. In terms of safety, it has been generally recognized in the industry that the uneven tension distribution of the rope will directly affect the life of its gear train and rope system, and accidents are prone to occur when the control is weak. In terms of comfort, for multi-rope hoisting systems such as passenger elevators used in public places, uneven tension distribution will cause undesirable vibration and noise in the car, affecting customer experience. [0003] 1. The existing measurement and adjustment techniques are as follows: [0004] Measure the tens...
