Balanced loading device for double-tension test

Abstract

The invention provides a balanced loading device for a double-tension test. The balanced loading device comprises a shell, a traction frame, a driving part and a traction rope, the two ends of the shell are used for being connected with a fixing frame respectively, a sliding way is arranged in the middle of the shell, and two leading-out pulleys symmetrically distributed with the sliding way as the center and two guiding pulleys are rotationally connected into the shell. One end of the traction frame is slidably connected into the slide way, and the traction frame is rotatably connected with a traction pulley with the center aligned with the axial direction of the slide way; the driving piece is arranged in the shell, and the output end is connected with the traction frame; the traction rope is sleeved on the traction pulley, two ends of the traction rope sequentially penetrate through the guide pulleys and the leading-out pulleys respectively and are correspondingly connected with the two points to be measured respectively, and the extension direction of the two ends of the traction rope penetrating out of the shell and the axial included angle of the slideway are equal. The balanced loading device for a double-tension test provided by the invention is high in test precision and can be suitable for components with different structures, so that test consumables are saved, and the test cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of mechanical testing devices, and more specifically relates to a balanced loading device for a double-pull test. Background technique [0002] At present, when testing the mechanical stability of structural parts, it is usually necessary to perform an equal tension test on two points spaced apart from each other on the structural part. The current method used in the test is to connect a tension device to the two test points respectively. , and then make the two sets of tension devices apply the same tension at the same time for the test. It is difficult to keep consistent the tension applied by the two sets of tension devices to the corresponding test points in this way, which will lead to deviations in test results and affect the judgment of the mechanical stability of structural parts. In addition, this measurement method needs to be specific to different The structural parts are matched with the tensile...
