Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of steel wire tension testing, and in particular relates to a steel wire rope tension tightness testing device. Background Art
[0002] Steel wire rope is a spiral steel wire bundle twisted together according to certain rules with steel wires that meet the requirements of mechanical properties and geometric dimensions. Steel wire rope is composed of steel wire, rope core and grease. Steel wire rope is first twisted into strands by multiple steel wires, and then a certain number of strands are twisted into a spiral rope with the rope core as the center. It provides lifting, traction, tensioning and load-bearing functions in material handling machinery. Steel wire rope has high strength, light weight, stable operation and is not easy to break. The tension of the steel wire rope is a necessary condition to ensure its normal operation. Only by setting the tension correctly can the working efficiency and service life of the steel wire rope be guaranteed;
[0003] When using wire ropes at a construction site, it is often necessary to use multiple wire ropes at the same time to bear the force. This requires ensuring that the tension of each wire rope remains consistent. If the tension of the wire ropes is different, it will cause uneven force and affect the operation effect.
[0004] To this end, those skilled in the art have proposed a wire rope tension and tightness testing device to solve the problems raised by the background technology.
[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the utility model, therefore, it may include prior art that is not known to ordinary technicians in this field. Utility Model Content
