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 repairing unit, which includes a milling device X1 without a grinding device, and the milling device X1 realizes online dynamic shaping of the left and right rails; as figure 2 As shown, the milling device X1 includes a supporting base I, on which a first Y-guiding rail Y1 and a second Y-guiding rail Y2 are installed on the supporting base I32, and a first Z-guiding rail is installed on the base plate IJ1 of the first Y-guiding rail Y1 Z1, the second Z-guiding rail Z2 is installed on the base plate IIJ2 of the second Y-guiding rail Y2, through the first Y-guiding rail Y1 and the first Z-guiding rail Z1, the left milling device on the left rail can be used to shape the rail profile The Y-direction and Z-direction displacements can be realized by the second Y-guiding rail Y2 and the second Z-guiding rail Z2 when the right milling device on the right rail is shaping the rail profile.

Embodiment 12

[0101] Embodiment 1.2: A rail profile repairing unit, the same as embodiment 1.1, the difference is that it also includes a second set of milling device X2, and the second set of milling device X2 has the same structure as the milling device X1, such as Figure 6 and 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 repairing unit, 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 rail profile repairing unit, which includes at least one set of milling device, the milling device realizes online dynamic shaping of left and right rails; the milling device includes a supporting base I, and the supporting base I is equipped with a first Y guide rail (Y1) And the second Y-guided rail (Y2), the first Z-guided rail (Z1) is installed on the substrate I (J1) of the first Y-guided rail (Y1), and the substrate II (J2) of the second Y-guided rail (Y2) is installed ) is equipped with a second Z guide rail (Z2). A kind of railway rail profile repairing equipment, it comprises at least two car frames, establish two car frames and be called rear car frame (28) and front car frame (18), the operation driving of the front car frame (18) rear end At least one set of grinding device (17) is installed in front of the bogie, and the main body of the milling device is equipped with a milling disc (36), and the diameter of the milling disc (36) is not less than 600mm. In the railway rail profile repairing equipment provided by the present invention, a set of 600mm-diameter milling discs is arranged on the front frame, and various power systems and control units are rationally 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 ...
