The invention discloses an automatic-clamping steel cable tension tester and a testing method thereof. The tester comprises a hydraulic power unit and a mechanical unit. The mechanical unit comprises a wedged clamping device, a loading guide unit and a walking device. Execution elements of the hydraulic power unit include a loading cylinder and a clamping cylinder. The free end of a steel cable is clamped directly by two wedged clamp plates of the wedged clamping device driven by the clamping cylinder. The assembly end of the steel cable is connected with a flat lug of a guide connector of the loading guide unit through a pin, the screw end of the guide connector is connected with a force sensor, and a guide is driven by the loading cylinder. The automatic clamping way driven by the hydraulic cylinder brings convenience to clamping, causes low damages to the steel cable as processes such as scattering, cleaning, hooking and lead pouring in production of steel cable samples are omitted, thereby improving stretching efficiency greatly. The automatic-clamping steel cable tension tester has the advantages of compact structure, reliable performance and high mobility, and is adaptable to quality tests of large-stroke and high-safety steel cables and components thereof before being delivered from plants.
Description
technical field [0001] The invention relates to a steel cable horizontal tensile testing machine, in particular to a mechanical performance test device for steel cable components delivered from the factory. Background technique [0002] Wire rope has become an essential component or material in the fields of metallurgy, mining, shipbuilding and aerospace. Its quality has also been concerned by many industries, and a lot of manpower and material resources have been invested in the research and product development of steel wire rope. Among them, the tensile strength is the most important index to evaluate the quality and safety of steel cables. [0003] At present, when the steel cable tensile testing machine on the market performs a tensile test, it is first necessary to sample the steel cable, and then use the method of filling lead or threading a pin for breaking tension. The method of sampling and testing is unstable and deviated, and it is not suitable for steel cable as...
