In the existing aluminum alloy railway vehicle, the sleeper beam is used as an important connecting structure connected with the bogie, not only carries the running load of the vehicle, but also provides necessary space for wiring under the vehicle, and through holes are required to be arranged on the side face of the sleeper beam. In order to prevent corrosion of a bogie center pin or an air spring area caused by impurities and water flow entering a sleeper beam cavity, the requirement of line passing is met, and meanwhile, the inner space of the sleeper beam is isolated from the outside.
The sleeper beam 1 used in the existing railway vehicle is formed by welding aluminum alloy sections, the guide cylinder 2 penetrates through the through hole of the sleeper beam 1, two ends of the guide cylinder are slightly shorter than the outside of the sleeper beam 1 by 3-5mm, and the metal guide cylinder 2 is welded to play a role in sealing. However, the body sleeper beam is in a flat shape, and the welding guide cylinder 2 and the circumferential welding seams 9 of the sleeper beam 1 cannot be completely welded or cannot meet the welding standard requirement due to limited space, auxiliary sealing is required to be carried out by coating and beating the sealant 10 (see fig. 1), and the sleeper beam through pipe structure sealed by the sealant is completely welded, so that the maintenance requirement of the interior of the subsequent sleeper beam is not met.
In addition, in the prior aluminum alloy subway project, as the running speed is increased, a vertical shock absorber is required to be arranged on the bogie, meanwhile, a shock absorber mounting seat 3 is arranged on the sleeper, the shock absorber mounting seat 3 is usually arranged below a sleeper tube hole, as the shock absorber mounting seat and an electric wire passing hole are crossed in space, as according to the prior welding guide tube structural design, a sealing guide tube at the position of the tube hole is welded in advance in the sleeper tube process to form a closed sleeper tube cavity, so that in the later rivet pulling process, due to the narrow space, a nail rod of a rivet 4 right below the sealing guide tube interferes with the sealing guide tube 2 before rivet pulling (see figure 2), and therefore, the sealing guide tube interference position needs to be penetrated Kong Birang; meanwhile, due to the fact that a certain failure rate exists in the rivet, when the rivet of the riveting piece fails in the riveting process, the rivet rod is deformed, and the failed rivet cannot be taken out. Therefore, when riveting failure occurs, the method is generally adopted to integrally destroy and cut off the external rivet caps of the rivets and knock the rest rivet parts into the sleeper beam die cavities, the method has great damage to rivet holes, and meanwhile, the rivet rods remained in the die cavities can cause abnormal sound and electrochemical corrosion.
