The invention discloses railway special line rail brazing equipment, and relates to the technical field of brazing, the railway special line rail brazing equipment comprises a main body unit which comprises a mobile crane, a lifting hook arranged on the mobile crane, a rail welding machine arranged on the lifting hook, and a rail body arranged on the rail welding machine; the pre-welding positioning unit comprises threaded rolling assemblies which are arranged above the rail body and located on the two sides of the rail welding machine. According to the railway special line rail brazing equipment, a threaded rotating shaft and a threaded roller on the pre-welding positioning unit make contact with a rail fixed on site in advance in the descending process of a rail welding machine, and in the continuous descending process of the rail welding machine, the threaded rotating shaft and the threaded roller rotate on a rail body and enable two rotating clamping plates to be close to each other till the threaded rotating shaft and the threaded roller are clamped and positioned on the rail body; and the rail welding machine is in a stable descending state when descending to make contact with the rail body, the stability of the rail welding machine in the descending process is improved, and the situation that the rail body is damaged due to the fact that the rail welding machine shakes in the welding process is avoided.
本发明公开了一种铁路专用线轨道钎焊设备,涉及钎焊技术领域,包括主体单元,包括移动式起重机、设置在移动式起重机上的吊钩、设置在吊钩上的焊轨机,以及设置在焊轨机上的铁轨本体;以及,焊前定位单元,包括设置在铁轨本体上方并位于焊轨机两侧的螺纹滚动组件。该铁路专用线轨道钎焊设备,通过焊前定位单元上的螺纹转动轴、螺纹滚筒在焊轨机下降过程中提前与现场固定好的铁轨接触,并在焊轨机继续下降的过程中,在铁轨本体上转动并使得两个转动夹板相互靠近,直至夹持定位在铁轨本体上,使得焊轨机在下降至与铁轨本体接触时为稳定下降的状态,提高了焊轨机下降过程中的稳定性,避免了焊接过程中焊轨机发生晃动导致铁轨本体受损的情况。
