Obviously, the described embodiments are only a part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0040] In the present application, the longitudinal direction is the length direction of the rail vehicle, the transverse direction is the width direction of the rail vehicle, and the vertical or vertical direction is the height direction of the rail vehicle.

[0042] Figure 1 The structural schematic diagram of a rail sewage suction vehicle frame provided by an embodiment of the present application is as Figure 1 shown. In view of the above problems, in the embodiments of the present application, a rail sewage suction vehicle frame is provided, which is used in cooperation with a sewage suction device, and includes: a front frame 10 and a rear frame 20.

The design structure is reasonable, the stiffness and strength of the overall frame are strengthened, the bending and torsion resistance performance of the frame is enhanced, and the stability of the overall frame structure is improved. Compared with the prior art in which large-section through main beams are used on both outer sides, the weight of the frame is effectively reduced, the manufacturing cost and difficulty are reduced, and at the same time, installation space and load margin are provided for installing working devices on the frame, making the operation process of the working device more convenient; the transverse pipe components provide installation positions for the installation of the sewage suction device, so that the sewage suction device is stably arranged on the frame, facilitating sewage suction operations; the strengthening assembly connects and strengthens the tops of the first box beam assembly and the transition beam assembly, improves the stability of the connection structure, makes the frame more stable, can meet the use requirements of long-term operation, and has a long service life.

The first box beam assembly and the main beam assembly are both variable cross-section structures. The front frame and the rear frame are connected through the variable cross-section structure, enhancing the stability of the connection structure. More specifically, the widths of both the front frame 10 and the rear frame 20 are 3000 mm, which meet the requirements of the frame of the railway sewage suction vehicle and can be applied to the railway clearance.
