Abstract

The invention provides a heavy rail clamping device, which comprises a heavy rail up-down limiting mechanism, a heavy rail left-right limiting mechanism and a pneumatic system fixed on a rack and the rack, wherein the heavy rail up-down limiting mechanism comprises a rocker mechanism, a down pressing roller protection device, a driving system and a horizontal elevation adjustment device; the heavy rail left-right limiting mechanism comprises a left limiting roller and a right limiting roller; and the pneumatic system comprises a down pressing cylinder, a left pushing cylinder, a right pushing cylinder, electromagnetic valves and other necessary pneumatic components. The clamping device carries out forced limiting and centering on movement of the heavy rail on a roller table, swinging of the heavy rail in a horizontal plane and jumping in a vertical plane are limited in a detection requirement permission range, the heavy rail flatness detection precision is ensured, and the precision of other related detection equipment is improved.

Description

technical field [0001] The invention relates to the field of heavy rail detection, in particular to a position-limiting and centering device for heavy rails in the heavy rail detection process. Background technique [0002] Flatness is one of the core indicators to measure the quality of high-speed railway heavy rail. When the heavy rail runs stably on the center line of the equipment, the detection efficiency is high and the detection results are reliable. Therefore, when designing the heavy rail inspection center, a guiding device for forcefully limiting the heavy rail is designed, and a control standard for the operating range of the heavy rail is established. [0003] Such as: NDT company standard [0004] The detection length of the heavy rail is up to 100m and the shortest is 9m; the curvature of the heavy rail up and down is ≤1mm / m. Left and right bending ≤ 2mm / m; total length of heavy rail: up and down bending ≤ 0.5%, left and right bending ≤ 1%, torsional bending ...
