Technical Field

[0002] Railcars are the main means of transportation for railway equipment maintenance, overhaul, infrastructure and other construction departments to perform tasks. Railcars are divided into heavy and light types. Railcars that can be evacuated from the line at any time by passengers are called light railcars; railcars that cannot be evacuated from the line at any time by passengers are called heavy railcars. Sound insulation wall panels are a high-performance constrained damping structural panel, which is composed of a high-performance viscoelastic damping sound insulation coating and a constrained damping layer. When the structural panel is vibrated by the impact of sound waves, the viscoelastic damping coating can effectively convert the vibration energy of the sound waves into heat energy and consume it, thereby playing a significant sound insulation role.

[0003] Existing rail cars generate very loud noise during transportation and need to be equipped with sound insulation wall panels for noise reduction. However, most of the sound insulation wall panels are of an integrated structure. When transported into the rail car, they are inconvenient to transport due to their large size. In addition, the sound insulation wall panels require too much manpower when assembled in the rail car, and the assembly is too cumbersome and inconvenient. Utility Model Content

[0023] In this embodiment, firstly, the slider 301 at the left end of one group of sound insulation wall panel bodies 1 is aligned with the slide groove 302 at the right end of another group of sound insulation wall panel bodies 1, and the slider 301 is inserted into the slide groove 302. The lower end of the fixing rod 304 is tapered, and the slider 301 presses against the lower end of the fixing rod 304 and pushes the fixing rod 304 upward, and then the fixing rod 304 is moved downward by the elastic force of the spring 305, and the bottom end of the fixing rod 304 presses against the groove 306 in the middle of the slider 301. Since the other side of the lower end of the fixing rod 304 is flat, the slider 301 is stuck in the slide groove 302. Multiple groups of sound insulation wall panel bodies 1 are spliced ​​together in this reciprocating manner. When replacing, the fixing rod 304 is pulled upward to move out the sound insulation wall panel body 1 to be replaced, so that it is more convenient to transport multiple groups of sound insulation wall panel bodies 1 into the rail car.
