| description | The utility model relates to a straightener for eliminating rail bottom residual stress of a steel rail, which comprises eight groups of flat rollers, a group of lifting flat rollers is additionally arranged at the outlet of the eighth group of flat rollers, the lifting flat rollers comprise a ninth flat roller, a motor, a flat roller rack, a guide frame and a lifter, the motor drives the ninth flat roller to rotate, the ninth flat roller and the motor are arranged on the flat roller rack, and the guide frame is arranged on the guide frame. The flat roller rack is connected with the guide frame in a sliding mode, and the lifter drives the flat roller rack to ascend and descend. Compared with the prior art, the utility model has the beneficial effects that: 1) the residual stress of the rail bottom of the steel rail is less than 250MPa through the latest method for measuring the stress of the rail bottom by the general office of railways; 2) the abrasion loss of the first eight groups of flat rollers is reduce |
