Problems solved by technology

[0003] The known milling, grinding and shaping equipment adopts one car to arrange two sets of milling devices and one set of grinding device. Due to the limitation of axle load, the diameter structure of the milling disc used by the milling device is small, for example, 600mm. Due to the small diameter of the milling disc, the amount of inertia during milling Small, the vertical component force of cutting is large, the work of the cutter head is unstable, the life of the cutter grain is short, and the residual wave amplitude is large, the accuracy and longitudinal smoothness of the rail section are not good

Embodiment 11

[0100] Embodiment 1.1: A rail profile repair vehicle, which includes a milling device X1 without grinding device, the milling device X1 realizes online dynamic shaping of the left and right rails; the milling device X1 includes a supporting base I, the supporting base The first Y-guiding rail Y1 and the second Y-guiding rail Y2 are installed on I, the first Z-guiding rail Z1 is installed on the substrate IJ1 of the first Y-guiding rail Y1, and the first Z-guiding rail Z1 is installed on the substrate IIJ2 of the second Y-guiding rail Y2. Two Z-guiding rails Z2, through the first Y-guiding rail Y1 and the first Z-guiding rail Z1, the Y-direction and Z-direction displacement of the left milling device on the left rail when shaping the rail profile can be realized, and through the second Y-guiding rail Y2 , The second Z guide rail Z2 can realize the Y-direction and Z-direction displacement when the right milling device located on the right rail is shaping the profile of the rail. ...

Embodiment 12

[0101] Embodiment 1.2: A rail profile refurbishment car, the same as embodiment 1.1, the difference is that it also includes a second set of milling device X2, and the structure of the second set of milling device X2 is the same as that of the milling device X1, such as Figure 9 As shown, the second set of milling devices X2 and the first set of milling devices X1 are arranged symmetrically with respect to the Y-direction center line of the vehicle frame, and are arranged below the vehicle frame.

Embodiment 13

[0102] Embodiment 1.3: A rail profile repair car, the same as Embodiment 1.2, the difference is that it also includes a third set of milling device X3, and the structure of the third set of milling device X3 is the same as that of the milling device X1. Three sets of milling devices X3 are arranged behind the first set of milling devices X1 and the second set of milling devices X2.

Abstract

A railway track profile shape modifying vehicle comprises at least one milling device. The milling device realizes left and right steel rail online dynamic shaping. The milling device comprises a supporting base body I, wherein a first Y-direction guide rail (Y1) and a second Y-direction guide rail (Y2) are mounted on the supporting base body I; a first Z-direction guide rail (Z1) is mounted on a base plate I (J1) of the first Y-direction guide rail (Y1) ; and a second Z-direction guide rail (Z2) is mounted on a base plate II (J2) of the second Y-direction guide rail (Y2). A railway track profile shape modifying equipment comprises at least two sections of frames, which are named as a rear frame (28) and a front frame (18); at least one set of grinding device (17) is mounted in front of an operation driving bogie at the rear end of the front frame (18); the main body of the milling device is provided with a milling disc (36); and the diameter of the milling disc (36) is not less than 600 mm. According to the invention, as one milling disc with diameter of 600 mm is placed on the front frame of the railway track profile shape modifying equipment, each power system and each control unit are reasonably arranged.

Description

technical field [0001] The invention relates to a railway rail maintenance method, in particular to a railway rail profile milling and refurbishment method, and corresponding equipment. Background technique [0002] Steel rails are important equipment for railway lines. In actual use, determine the reasonable service life of steel rails, implement the system of using steel rails in stages, and actively do a good job in the renovation of old rails. The renovation of old rails is usually divided into three categories: comprehensive shaping rails, general shaping rails and welded and reused long rails. Rail refurbishment technology: Uneven wear of rail ends, falling blocks, and scratches are one of the main forms of various damages and defects generated during the operation of rails. These diseases cause a huge additional impact on the rolling stock, aggravate the change of the line meter, not only shorten the service life of each component of the track, but also increase the ...
