Abstract

The invention provides an expansion joint test device, which relates to the technical field of urban rail transit. The expansion joint test device comprises a driving mechanism, a working platform, apressure sensor, a digital-display pull-push dynamometer and a control panel; the working platform is used for carrying the expansion joint test device; an output end of the driving mechanism is usedfor being connected with an expansion joint by virtue of the pressure sensor and drives the expansion joint to make reciprocating pulling movement; the digital-display pull-push dynamometer is electrically connected with the pressure sensor and used for displaying initial sliding force of the expansion joint; and the control panel is electrically connected with the driving mechanism and used for setting a pulling times of the expansion joint and obtaining anti-fatigue strength of the expansion joint according to the pulling times of the expansion joint. The expansion joint test device solves the technical problems of the prior art that the initial power and the anti-fatigue strength of the expansion joint cannot be simultaneously measured.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to an expansion joint testing device. Background technique [0002] The expansion joint is set at the proper position of the contact rail to adjust the phenomenon of thermal expansion and contraction caused by environmental changes and its own temperature rise. It is an important component of the contact rail system. [0003] Most of the current expansion joint testing equipment is mainly used to measure the initial sliding force, such as patent No. 201710173349.9, which is an expansion joint tensile test device. In fact, fatigue strength testing is also an important test item to verify the safety and service life of expansion joints. [0004] Based on this, the present invention provides an expansion joint testing device to solve the above technical problems. Contents of the invention [0005] The purpose of the present invention is to provide an expansion joint testi...
