The invention discloses a leveling truss for a high-speed rail tie connection test. The truss comprises a horizontal base, a first horizontal substrate and a support plate, a roller is arranged belowthe horizontal base, the left and right sides of the horizontal base are provided with connection inserting boards, a leveling cross bar penetrates through the inside of the first horizontal substrate, the first horizontal substrate is located above a mounting block, the inner side of a support plate is provided with a fixing ring plate, and the support plate is located above a sliding cover; theleveling truss for the high-speed rail tie connection test uses the first horizontal substrate to separately establish a horizontal detection reference for an entire truss structure, the connection between the mounting block and a telescopic frame is utilized, the vertical spacing between the first horizontal substrate and the horizontal base is adjusted, the telescopic frame is rotatably connected to a rotating shaft to achieve the retractable purpose of the structure of the telescopic frame, and according to the depth of the burying of the high-speed rail tie and different terrains, the height of the structure of the truss is adjusted to a reasonable extent.
Description
technical field [0001] The invention relates to the technical field of high-speed rail sleeper-rail connection testing, in particular to a leveling truss for high-speed rail sleeper-rail connection testing. Background technique [0002] The high-speed railway is a newly-built railway. China's railway construction technology level and development trend are already at the leading level in the world, and railway transportation is also developing towards better and faster development. When laying high-speed railway sleepers, in addition to measuring various geographical and environmental parameters In addition, it is also necessary to carry out a connection test on the sleeper rail, and calculate the connection parameters of the sleeper rail through a small-scale connection. There are generally two problems in the leveling truss. One is that it is not easy to install and fix itself. When connecting, the uneven connection between the truss and the truss also has a great impact on...
