Abstract

The invention provides a 1500t vertical united force testing machine instability preventing device. The instability preventing device is arranged on a lower platform of a load frame of a 1500t vertical united force testing machine. The instability preventing device comprises an instability preventing framework and an instability preventing support device. The instability preventing device can ensure that a test is smoothly completed, the length of a support rod can be adjusted, and the position of a support point can be vertically adjusted. The instability preventing device can be suitable for various specifications within a range of 2-7 / 8 inches to 5-1 / 2 inches. The instability preventing device is provided with a plurality of sets of clamps which are flexibly suitable for various types of tests. The instability preventing device is not needed to be detached after a test of series A and can be matched with a bending device for use when in a test of serious B. The 1500t vertical united force testing machine instability preventing device shortens a test cycle, reduces waste of labor and material sources, instability does not happen on a sample, and in addition, the device can be prevented from being damaged.

Description

technical field [0001] The invention relates to an anti-instability device for a 1500t vertical combined force testing machine. Background technique [0002] The 1500t vertical combined force testing machine is currently mainly used for performance evaluation tests and slippage tests of oil casing couplings with diameters from 2-7 / 8in to 5-1 / 2in. The constantly updated ISO13679 standard has increasingly stringent requirements for the performance evaluation test of oil casing couplings. Among them, in the composite force compression test, the compression value is close to the yield strength of the pipe body, which leads to the stability of the compression rod in engineering mechanics. In the absence of any anti-instability measures, the sample is prone to instability, making it difficult to successfully complete the test as required, and even cause unnecessary dangerous accidents. [0003] In engineering mechanics, a member whose longitudinal (length direction) dimension is ...
