Straightening equipment for high-speed rail or frog and straightening method thereof

Abstract

The invention discloses straightening equipment for a high-speed railway steel rail or frog and a straightening method of the straightening equipment. The straightening equipment comprises a rack; a workbench is arranged in the rack; a fixed cross beam is arranged on one side of the workbench; a movable cross beam is arranged on the other side of the workbench; a first driving device is arranged at the end of the rack; the output end of the first driving device is connected with the movable cross beam; the ends of the fixed cross beam and the movable cross beam are detachably connected with anejection head; a first rack part and a second rack part are arranged on each of the two sides of the rack; second driving devices are arranged in the first rack parts; the output ends of the second driving devices are connected with lifting rollers; third driving devices are arranged in the second rack parts; the output ends of the third driving devices are connected with sliding rails; and one or more sliding blocks are arranged on each sliding rail in a sliding manner. The straightening method can guarantee that the finally straightened high-speed railway steel rail or frog has better smoothness through the straightening equipment for the high-speed railway steel rail or frog.

Description

technical field [0001] The invention belongs to the technical field of metallurgical steel rolling equipment, and in particular relates to a straightening device for high-speed rail or frogs, and also relates to a straightening method for high-speed rails or frogs. Background technique [0002] China's high-speed rail mileage has leapt to the first in the world, and there are still many high-speed rail projects under active construction. As the core equipment in the construction of high-speed rail, rails and frogs have very strict requirements on their precision and quality, especially during the installation process, they need to be straightened or top-bent, and the required engineering standards are absolutely accurate . At present, the traditional rail pressure straightening method is mostly used in engineering. This method has low efficiency and poor flatness. It is not suitable for the current rapid development of high-speed rail. Therefore, it is very necessary to imp...
