[0017] The present invention is described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods or structures made by ordinary technicians in the field based on these embodiments are all within the scope of protection of the present invention.

[0018] In the description of the present utility model, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection of two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meaning of the terms can be understood according to the specific circumstances.

[0019] like Figure 1 As shown, the rail vehicle bogie bracket of the utility model comprises: a bottom plate 1, a first bracket 2 and a second bracket 3, the bottoms of the first bracket 2 and the second bracket 3 are fixedly arranged on the bottom plate 1, and the first bracket 2 and the second bracket 3 are arranged in parallel. During the implementation process, the spacing between the first bracket 2 and the second bracket 3 can be moved, and mounting holes can be regularly arranged on the bottom plate 1. The spacing can be adjusted by installing between different mounting holes, so that the first bracket 2 and the second bracket 3 can support rail vehicle bogies of different specifications.

[0020] The first bracket 2 and the second bracket 3 have the same structure, and the movement of the two on the bottom plate 1 can be achieved by providing waist-shaped holes on the bottom plate 1 .

[0021] like Figure 2 and Figure 3As shown, the first bracket 2 includes: a first support rod 21, a second support rod 22, a first support seat 23 and a second support seat 24. The first support rod 21 and the second support rod 22 are fixed in parallel on the bottom plate 1. The first support seat 23 connects one end of the first support rod 21 and the second support rod 22, and the second support seat 24 connects the other end of the first support rod 21 and the second support rod 22. The two sets of wheel hubs of the rail vehicle bogie are supported and limited by the first bracket 2 and the second bracket 3, and the first bracket 23 and the second support seat 24 are moved to adapt to the use of bogies of different specifications.

[0022] During the implementation process, the extreme dimensions of the existing bogie specifications are taken into consideration. The maximum dimensions of the first bracket 2 and the second bracket 3 are: 1660×600×170mm. The main frame is made of Q235A steel pipe welding, with a total weight of about 35Kg.

[0023] like Figure 4 As shown, the first support seat 23 includes: a base 25, a V-shaped groove 26 and an elastic protective layer 27. The two ends of the base 25 are detachably fixedly connected to the first support rod 21 and the second support rod 22 through a connector 28. A V-shaped groove 26 is provided on the top of the base 25, and the elastic protective layer 27 is coated in the V-shaped groove 26. The position of the bogie wheel hub is limited by the V-shaped groove 26, and the elastic protective layer 27 is used to prevent the wheel hub from directly colliding with the V-shaped groove 26. In the production process, the corresponding shape is directly cut out of the steel plate and then welded and formed, including the connector 28, which is welded at both ends of the base 25. The elastic protective layer 27 is a rubber strip, which is bonded and fixed in the V-shaped groove 26. Considering the problem of wear, when replacement is required, the original elastic protective layer 27 can be directly scraped off and a new one can be bonded.

[0024] The structure of the first support seat 23 is the same as that of the second support seat 24. The same structure can meet the requirements for fixing the wheel hub, and the structure is more convenient for processing and production.

[0025] The connecting member 28 includes: a first connecting piece 281, a second connecting piece 282, a fixing hole 283 and a bolt 284. The first connecting piece 281 and the second connecting piece 282 are mirror-imaged at both ends of the base 25. The fixing holes 283 are evenly and regularly distributed on the first support rod 21 and the second support rod 22. A plurality of bolts 284 are provided, and the bolts 284 pass through the first connecting piece 281 and the second connecting piece 282 and are connected to the fixing holes 283. The first supporting seat 23 or the second supporting seat 24 is installed between the first support rod 21 and the second support rod 22 through the first connecting piece 281 and the second connecting piece 282, and the fixing of bogies of different specifications is conveniently adapted through a plurality of regularly arranged fixing holes 283.

[0026] The first connecting piece 281 is U-shaped, the first connecting piece 281 covers the first support rod 21 and the bolt 284 passes through the first connecting piece 281 and the first support rod 21 to fix, the second connecting piece 282 is U-shaped, the second connecting piece 282 covers the second support rod 22 and the bolt 284 passes through the second connecting piece 282 and the second support rod 22 to fix. The U-shaped first connecting piece 281 and the second connecting piece 282 are connected to the first support rod 21 and the second support rod 22 up and down, and the position of the base 25 is fixed by the bolt 284. In production, the first connecting piece 281 and the second connecting piece 282 are first bent into a U shape, with the notch facing outward, and the connecting edge is welded to the base 25, so that firstly, it is convenient to slide the base 25 on the first support rod 21 and the second support rod 22 when adjusting the wheelbase, and secondly, it is more tightened by the upper and lower fixed connection.

[0027] like Figure 5 As shown, two handles 211 are provided on the top of the first support rod 21, and two handles 211 are provided on the top of the second support rod 22. The handles 211 are provided to facilitate manual carrying of the bracket.

[0028] The bottom of the first support rod 21 and the second support rod 22 are detachably mounted on the bottom plate 1. Through the detachable mounting, the mounting hole position of the support seat on the connecting rod is adjusted according to the loading bogie rules or other track gauge support rods are replaced to adapt to special track gauge bogies.

[0029] When using it again, first determine the bogie gauge, adjust the distance between the first support seat 23 and the second support seat 24 to match the bogie gauge, then confirm the wheelbase of the bogie, lock the first bracket 2 and the second bracket 3 with the base plate 1, drop the bogie onto the first bracket 2 and the second bracket 3, ensure that the wheel hubs fall into the first support seat 23 and the second support seat 24, and fix the bogie to the transport vehicle with straps to complete the bogie packaging.

[0030] The above are only some embodiments of the present invention. It should be pointed out that for ordinary technicians in this field, other modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
