Finish-milling unit of mobile rail-milling car
A finish-milling unit of a mobile rail-milling car comprises at least one tool rest (1); the tool rests (1) are connected with milling driving devices (2); the lower end of each tool rest (1) is provided with a milling head (3); the output end of each milling driving device is connected with a drive shaft of the corresponding milling head through a mechanical transmission device; one side of each tool rest (1) is further connected with a group of hydraulic vertical movement and positioning devices (4) and a group of electric horizontal movement and positioning devices (5); each group of hydraulic vertical movement and positioning devices (4) is connected with the corresponding electric horizontal movement and positioning devices (5); the electric horizontal movement and positioning devices (5) are used for positioning the horizontal positions of milling tools. The finish-milling unit has the advantages that a steel rail which is roughed can be finely dressed again, dressing effect is good, and operating efficiency is high; omission of the grinding method for secondary dressing of the steel rail leads to low environmental pollution; owing to the tool rests capable of rotating around their rotational axes, the tool rests and blades on the same are convenient to change.
