Description
Technical field
The utility model relates to a kind of device for measuring force of tension tester, and particularly a kind of device for measuring force for tension test for chain cable, belong to the testing machine technical field.
Background technology
Marine anchor chain is the important equipment that is related to safety of ship, and because marine anchor chain need to work long hours under the load cycling effect, its mechanical property must meet the requirement of relevant international standard and international organization's standard.The related specifications of each classification society and relevant international standard, national standard are all stipulated, manufacture the Anchor chain link of shaping after heat treatment, must carry out tensile test to whole chain links by the tensile load value of different size and intensity rank regulation, chain link after test should reach symmetrical geometry, flawless, pit, and size is no more than the tolerance of regulation, after tensile test, cable link has produced plastic yield, cable link length after elongation has met the regulation of relevant specification and standard, and while guaranteeing to use, anchor chain can pass through the smooth and easy folding and unfolding of anchor windlass; The more important thing is, anchor chain has born the tensile load of regulation, and the major accident of safety of ship can not occur to affect because of the anchor chain fracture.The horizontal type structure that anchor chain lacerating machine adopts hydraulic jack to load, to adapt to the tensile test needs of 27.5 meters long one assembled lengths.The device for measuring force of anchor chain lacerating machine should be able to accurately show the tensile load that one assembled length is applied, anchor chain lacerating machine is as a kind of dedicated tensile test machine that needs measurement verification, its device for measuring force must carry out regular measurement verification through metrological service's Application standard dynamometer, make national mete-wand be delivered to the anchor chain lacerating machine of the calibrating that is measured through metering value transmission system, just can guarantee the accuracy of tension test for chain cable.
Oil pressure when existing anchor chain lacerating machine adopts oil pressure sensor to measure the load cylinder loading, in the dynamometry controller, the piston area of hydraulic jack is set as constant, the oil pressure of load cylinder during loading is multiplied by the tensile load that piston area can obtain anchor chain is applied, the tensile load value shown due to the dynamometry controller obtains by calculating indirectly, the power value obtained with direct-detection is compared, and adopts the mode of the indirect dynamometry of oil pressure sensor obviously not as the former.
Summary of the invention
The purpose of this utility model is to provide a kind of energy direct-detection and shows the anchor chain lacerating machine force cell device of the tensile load value that anchor chain is applied.
The utility model is achieved by the following technical programs:
