[0041] In the embodiment, the support positioning module 2 comprises a base 21 located below and connected with the linear guide rail 11 and a support positioning part 22 located above the base 21, and the support positioning part 22 is detachably connected with the base 21 through a connecting piece. Since the support positioning part 22 is detachably connected with the base 21, when the underframe of the railway vehicle is produced and processed, the support positioning part 22 can be replaced according to different types of cross beams.

[0042] Specifically, the base 21 comprises a sliding part 211 connected with the linear guide rail 11 and capable of moving along the extension direction of the linear guide rail 11 and a stand 212 located above the sliding part 211, and the bottom end of the stand 212 is fixedly welded with the sliding part 211.

[0043] A protruding part 2121 protruding upward is arranged on the top of the stand 212, and the protruding part 2121 is integrally formed with the stand 212. The number of the protruding part 2121 is one or more, and in the embodiment, the number of the protruding part 2121 is two. A number of clamping grooves 221 equal to the number of the protruding part 2121 is arranged on the bottom of the support positioning part 22, and the clamping grooves 221 are communicated with the side walls of the support positioning part 22. The shape of the clamping grooves 221 matches the shape of the protruding part 2121. The distance between the two clamping grooves 221 is the same as the distance between the two protruding parts 2121.

[0044] When the support positioning part 22 and the base 21 are assembled together, the protruding part 2121 is matched with the clamping groove 221 on the support positioning part 22 one by one. After the protruding part 2121 is matched with the clamping groove 221 one by one, the protruding part 2121 is inserted into the inner part of the matched clamping groove 221, and then the protruding part 2121 and the support positioning part 22 are fixed together through bolts. Through the cooperation between the protruding part 2121 and the clamping groove 221, the installation position of the support positioning part 22 is limited, so that the support positioning part 22 is installed at the same position on the top of the base 21 every time.

[0045] Specifically, the sliding part 211 comprises a horizontal plate 2111 located above the linear guide rail 11, and the horizontal plate 2111 is arranged horizontally. Two vertical plates 2112 vertically extending downward are arranged on the bottom end of the horizontal plate 2111, the vertical plates 2112 are parallel to the side walls on the left and right sides of the linear guide rail 11, and a distance is left between the two vertical plates 2112 and the linear guide rail 11. The linear guide rail 11 passes through between the two vertical plates 2112. The top of the vertical plate 2112 is connected with the horizontal plate 2111. The vertical plate 2112 and the horizontal plate 2111 can be fixed through welding or integrally formed.

[0046] A locking bolt 2113 is arranged on the vertical plate 2112 and horizontally penetrates the vertical plate 2112 from the side away from the linear guide rail 11, and is threadedly connected with the vertical plate 2112. The height of the locking bolt 2113 is lower than the top end surface of the linear guide rail 11. When the locking bolt 2113 moves towards the linear guide rail 11, the locking bolt 2113 can abut against the linear guide rail 11 and apply a pressing force to the linear guide rail 11. When the locking bolt 2113 applies the pressing force to the linear guide rail 11, the relative position between the sliding part 211 and the linear guide rail 11 is locked. When the locking bolt 2113 does not abut against the linear guide rail 11, the sliding part 211 can move along the extension direction of the linear guide rail 11 on the linear guide rail 11.

[0047] Preferably, the number of the locking bolts 2113 on each vertical plate 2112 is multiple, and the arrangement direction of the multiple locking bolts 2113 is along the extension direction of the linear guide rail 11.

[0048] In the embodiment, the side wall on the left and right sides of the linear guide rail 11 is provided with a guide groove 112, and the extension direction of the guide groove 112 is arranged along the extension direction of the linear guide rail 11. The sliding part 211 is provided with a clamping block 2114 which extends into the guide groove 112 and can move along the extension direction of the guide groove 112, and the clamping block 2114 is welded or integrally formed with the horizontal plate 2111. By matching the clamping block 2114 with the guide groove 112, the sliding part 211 cannot be separated from the linear guide rail 11, which ensures that the support positioning module 2 moves more stably during position adjustment.

[0049] In the embodiment, the pressing device 3 adopts a vertical flange clamp which is fixed on the side wall of the stand 212 of the base 21. The pressing head of the vertical flange clamp is horizontally spaced from the support positioning part 22. The side surface of the support positioning part 22 towards the pressing part of the vertical flange clamp is a positioning surface which is a vertical surface. When the support positioning part 22 supports the cross beam, the cross beam abuts against the positioning surface of the support positioning part 22, and the pressing head of the pressing device 3 can apply a pressing force to the cross beam so that the cross beam tightly abuts against the positioning surface of the support positioning part 22.
