Abstract

The invention relates to the field of railway, and discloses a fastener buckling pressure test device and method. The device comprises a clamp for clamping a fastener; a force application apparatus for applying pressure to the clamp so as to enable the clamp to lift the fastener; a pressure measurement apparatus for measuring a pressure value applied by the force application apparatus in the process when the fattener is lifted; a deformation measurement apparatus for measuring a deformation amount of an insulation gauge block, wherein the fastener is buckled to the insulation gauge block; and a control apparatus for acquiring the deformation amount and the pressure value and determining that the corresponding pressure value when the deformation amount stops changing is buckling pressure of the fastener.

Description

technical field [0001] The invention relates to the field of railways, in particular to a buckle pressure testing device and method. Background technique [0002] The buckling pressure of railway track fasteners is one of the technical indicators for evaluating the quality of fasteners. [0003] At present, the method of measuring the fastening force of bolt fasteners is obtained through a series of conversions based on the bolt tightening torque. For type III elastic fasteners without bolts, the fasteners can only be removed and sent to the laboratory testing machine for testing. [0004] In 2012, China Railway Longchang Railway Equipment Co., Ltd. invented a test platform for measuring the buckle pressure on the railway site. The fasteners were removed and installed on the test platform, and the fasteners were loaded for testing, and the buckle pressure of the fasteners was calculated according to the loading curve. [0005] Both of the above two methods require the fast...
