Because the side wall 100 of the locomotive is huge and the structure of the side wall 100 is different according to different vehicle types, the main frame 1 is used as an integral supporting structure in the scheme, a plurality of auxiliary frames 2 are combined to be respectively fixed at each position in the length direction of the side wall 100, and on the basis that the auxiliary frames 2 are distributed to support the side wall 100, the clamping and fixing of various different types of side walls 100 can be realized by combining the profiling assemblies 3 corresponding to the two transverse edge structures of the side wall 100, so that a good operation basis is provided for welding.

On the basis of the above embodiment, the main frame 1 includes a longitudinal rail extending in the longitudinal direction, and the lower portion of the sub-frame 2 is slidably connected to the longitudinal rail. As described above, since the side wall 100 of different vehicle types is required to be considered, the sub-frame 2 is configured to be movable longitudinally along the main frame 1. A locking structure is arranged between the auxiliary frame 2 and the longitudinal guide rail, and the locking structure only needs to be capable of fixing the position of the auxiliary frame 2 on the main frame 1. The specific structure is not limited and can be realized by the prior art, such as a lock pin, a fastening nut and the like.

On the basis of the above embodiment, referring to fig. 4 to 7, the sub-frame 2 includes a base 20, the base 20 being of an elongated structure, the underside of which is slidably connected to the guide rail; a positioning component is arranged on the upper side of the base 20; the positioning assembly comprises a first positioning part 21 and a second positioning part 22 which are positioned at two lateral sides of the base 20, and the first positioning part 21 is arranged corresponding to the upper edge of the side wall 100 in the use state; the second positioning portion 22 is disposed corresponding to a lower edge of the sidewall 100 in a use state. The first positioning part 21 and the second positioning part 22 are arranged on the base 20, and the first positioning part 21 and the second positioning part 22 can be close to or far from each other; the profile modeling unit 3 is provided with a first profile modeling block 31 and a second profile modeling block 32 corresponding to the first positioning portion 21 and the second positioning portion 22, respectively.

Because the arc-shaped structure exists at the upper position of the side wall 100 of most locomotives in use, the first supporting block 231 structure is not suitable for the arc-shaped structure, and therefore the second lower supporting part 24 is arranged for the arc-shaped structure. In order to meet the adaptation of different vehicle types, the second lower supporting block 241 needs to have a lateral movement capability and to be able to lift itself. The second lower supporting block 241 of the present embodiment is combined with the base 20 in a sliding connection manner, such as a sliding rail structure, so that it can move laterally along the base 20. The lifting of the second lower supporting block 241 can be achieved by means of the prior art, such as a manual, electric, pneumatic or hydraulic lifting rod structure. The manual mode is taken as an example in the scheme, the lifting part of the second lower supporting block 241 is limited by means of the cooperation mode of the screw rod nut, the lifting part can only be lifted and cannot rotate, and then the screw rod is connected with the inner thread of the second lower supporting block 241 in a threaded connection mode. The horizontal position of the screw rod is fixed, so that the screw rod can only rotate without height change, and the screw rod can be rotated when the screw rod needs to be adjusted. To facilitate the observation of the size, graduation marks may be provided on the elevating portion of the second lower support block 241 so as to be a raised or lowered displacement value thereof.

On the basis of the above embodiment, the sub-frame 2 further includes a cross rail 201 fixedly provided on the upper side of the base 20, the cross rail 201 extending in the lateral direction, the cross rail 201 being provided one for each of the first positioning portion 21 and the second positioning portion 22; the first positioning portion 21 and the second positioning portion 22 are slidably connected to the base 20 via corresponding cross rails 201.

The first positioning portion 21 and the second positioning portion 22 need to be laterally movable. This scheme is introduced the structure of rail 201 and is realized this purpose, and first location portion 21 and second location portion 22 set up respectively can rail 201 sliding connection's pedestal structure, and all correspond to setting up locking structure. In order to ensure that there is sufficient force for pressing the profile, a hydraulic cylinder may be added, by means of which the first positioning portion 21 is pulled in the present embodiment. The cylinder body of the hydraulic cylinder is fixedly connected with the base 20, and the movable end is connected with the pedestal of the first positioning portion 21. So that the first positioning portion 21 can be driven to press the profile. Considering that only one side needs to be applied with force, one hydraulic cylinder is arranged on each subframe 2 to meet the requirement.
