The invention discloses a steel rail weld joint measuring and grinding device. The steel rail weld joint measuring and grinding device comprises a main controller, a height adjusting mechanism and a grinding head, wherein the height adjusting mechanism is electrically connected with the main controller, the grinding head comprises a mounting base, a driving part, a grinding tool and a measuring assembly, the mounting base is connected with the height adjusting mechanism, the mounting base is provided with a mounting hole, and the driving part penetrates through the mounting hole and is connected with the mounting base; the grinding tool is connected with the driving part, the measuring assembly is connected with the mounting base, the measuring assembly comprises a positioning box and an infrared range finder, the positioning box is connected with the mounting base, the infrared range finder is arranged in an inner cavity of the positioning box, the infrared range finder is electrically connected with the main controller, and the infrared range finder is used for measuring the height of a weld bead on steel rail. According to the steel rail weld joint measuring and grinding device,the height of the weld bead is measured through the infrared range finder, the height of the grinding head can be adjusted by the main controller, so that the adjustment of the steel rail grinding depth is realized, and safe driving of the train is guaranteed.
Description
technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a rail weld seam measuring and grinding device. Background technique [0002] The standard length of the rails produced by the steel factory is 25 meters or 100 meters. After the standard length rails are transported to the rail welding base, the rails are welded and connected into 500-meter-long seamless rails, and then transported to the railway line for laying. The railway line site During laying, special equipment is used to weld the 500-meter-long rails in turn to form a full-line seamless rail. There is no mechanical connection slit at any position of the rail, and the train runs very smoothly. When the rails are welded at the rail base, a weld seam is formed at the welding point of every two rails. The thickness of the weld seam is higher than the surface of the rail to form a weld bead protruding from the surface of the rail. The weld bead must be ground off...
