Self-balancing device and self-balancing method for steel wire tension

Abstract

The invention discloses a steel wire rope tension self-balancing device and a self-balancing method thereof. The steel wire rope tension self-balancing device is of an eudipleural structure and comprises an upper limiting switch, a rack, an upper positioning and guiding support beam, a steel wire rope connector, a gear, a lower bracket, an upright column, a lower positioning and guiding support beam and a lower limiting switch. According to the steel wire rope tension self-balancing device, when a lifting container ascends or descends to stop positions, in the process that personnel enter andexit or goods enter and exit, a lifting steel wire rope on the small-tension side can be controlled to lift by an electric control device of a steel wire rope lifting and conveying system according tothe feedback of the upper limiting switch on the top end of the rack or the lower limiting switch on the bottom end of the rack, and the rack on the large-tension side is driven to move downwards through the driving of a gear rack so as to balance the tension. The steel wire rope tension self-balancing device has the advantages of the simple structure and reliability in movement and is especiallysuitable for the lifting and conveying system for lifting and conveying through the steel wire rope, the tension of each lifting steel wire rope can be automatically adjusted, and the stress is uniform.

Description

technical field [0001] The invention relates to a steel wire rope tension self-balancing device and its self-balancing method, in particular to a steel wire rope tension self-balancing device and its self-balancing method suitable for hoisting transportation systems such as mine hoisting and traction elevator hoisting, which are lifted and transported by steel wire ropes The method belongs to the technical field of steel wire rope hoisting transportation. Background technique [0002] Mine hoisting, traction elevator hoisting and other hoisting transportation systems that use changing potential energy for transportation, in which wire ropes are wound on hoisting drums and hoisting by driving wire rope drums is the most widely used, usually divided into single-container hoisting systems (hoisting wire ropes) One end is connected to a lifting container such as a cage or a car, and the other end is connected to a balance weight) and a multi-container lifting system (both ends o...

Problems solved by technology

[0004] At present, the tension adjustment of hoisting wire ropes usually uses tension measuring devices to measure the tension of each hoisting wire rope multiple times to determine the force of each hoisting wire rope, and then adjust the rope head of the corresponding hoisting wire rope through a telescopic control mechanism such as a balance hydraulic cylinder. Adjustment is performed to balance the tension of the wire rope. This traditional adjustment method usually requires a hydraulic system or an electric control system. The mechanism setting is relatively complicated, and the work reliability is relatively poor. It is easy to cause misjudgment or failure due to factors such as dust coverage or leakage.
