Problems solved by technology

In addition to the relatively large design costs, the disadvantage of a large number of functions leads to the fact that in order to machine the side of the rail head opposite the face mill, the face mill must be used at relatively large intervals in the longitudinal direction of the rail, which results in some Uneven machining of both sides of the rail head under conditions
[0004] Similar disadvantages lead to the case of another known device (EP0148089A2), in which the running surface is machined on both sides of the longitudinal center by means of a milling head designed as a face milling cutter, but which must have a correspondingly inclined axis used in the case of the rail head, because the peripheral milling cutter for the longitudinal side of the rail head must be arranged before or after the normal milling head

Embodiment Construction

[0019] as available from figure 1 As inferred in , the device 1 according to the invention for reworking the rail head 2 of a rail 3 of a railway track by machining is arranged on a rail vehicle 4 , and the device 1 moves along the rail 3 with the help of the rail vehicle 4 . The device 1 has a frame 5 mounted on the rail vehicle 4 , which is vertically adjustable with the aid of a lifting drive 6 on the rail vehicle 4 and supported via guide rollers 7 on the rail head 2 . These guide rollers 7 not only guide the frame 5 vertically relative to the rail 3 , but also guide the frame 5 transversely.

[0020] according to figure 2 , the frame 5 receives a gearbox 10 connected to a rotary drive 9 to enable two machining tools to be driven synchronously in opposite directions in the manner of an end mill 11 , said frame 5 being connected to a rail vehicle 4 by a shaft 8 With a vertical shift, however, this is not required. The axes of rotation 12 of these face milling cutters 11...

Abstract

The invention relates to a device (1) for reworking the running surface (17) of a rail head (2) by machining, comprising a frame (5) guided along the rail head (2), in which frame two machining tools are supported on both sides of the rail head (2). The two machining tools can be rotationally driven in opposite directions and can be placed against the running surface (17) at the end face of said machining tools. In order to create advantageous machining conditions, the machining tools are designed as face milling cutters (11), the rotational axes (12) of which extend in a common plane (13) and the cutting areas of which overlap each other transversely to the longitudinal direction of the rail head (2), and the two face milling cutters (11) are connected to a common rotational drive (9) by means of a transfer gearbox (10).

Description

technical field [0001] The invention relates to a device for reworking the running surface of a rail head by machining, having a frame guided along the rail head, two machining tools mounted on both sides of the rail head, the two machining tools being drivable for Rotates in the opposite direction and is able to approach the running surface head-on. Background technique [0002] Due to relatively high axial loads and high travel speeds, the track is usually tensioned to the yield point of the track material and is thus subject to wear, which adversely affects the profile of the running surface of the rail head, making it difficult for track maintenance , the running surface must be reworked. For this purpose, a grinding assembly is known (AT344772B) which has at least two cup wheels arranged in succession in the longitudinal direction of the rail head and approached frontally on the opposite side of the rail head. A running surface, the at least two cup wheels have abrasi...
