Description
Technical Field
[0001] This utility model relates to the field of locomotive technology, and in particular to a traction transformer mounting structure and a locomotive. Background Technology
[0002] Railway transportation plays a vital role in the transportation sector, and increasing locomotive speed can effectively improve railway transport efficiency. With the increasing speed of locomotives, lightweighting has become increasingly important. Lightweighting is a crucial means of improving locomotive performance, energy efficiency, and economy, especially in the field of electric locomotives. Lightweighting can effectively reduce locomotive traction power, improve the smoothness of vehicle operation, reduce locomotive noise, suppress track damage caused by vehicle operation, and save costs.
[0003] In recent years, with the rapid development of power batteries, electric locomotives have gradually moved towards electric-electric hybrid power. Hybrid locomotives need to place the power batteries in the dry mechanical room inside the locomotive. However, the mechanical room contains equipment such as air cylinders and electrical cabinets, and the space is tight. The traditional layout of electric locomotive components has the problem of insufficient interior space. Increasing the interior space will lead to an increase in the overall size of the locomotive, resulting in a reduction in the locomotive's lightweight level and affecting operating efficiency.
[0004] Therefore, a traction transformer mounting structure and locomotive are needed to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a traction transformer installation structure and locomotive that facilitates the arrangement of power batteries without increasing the overall size of the locomotive, thereby improving the locomotive's lightweight level and operating efficiency.

[0034] When arranging power batteries on a locomotive, in order to facilitate the arrangement of the power batteries without increasing the overall size of the locomotive, improve the locomotive's lightweight level, and enhance its operating efficiency, such as... Figures 1-3As shown, this utility model provides a traction transformer mounting structure. The traction transformer mounting structure includes a support plate 1, an oil tank 2, a first fixing frame 3, and a second fixing frame 4.
[0035] The support plate 1 extends along a first direction, which is the length direction of the support plate 1. The oil tank 2 is fixedly mounted on the upper surface of the support plate 1, and a traction transformer body is installed inside the oil tank 2. A first fixing frame 3 and a second fixing frame 4 are fixedly mounted on both sides of the oil tank 2 along the first direction. Both the first fixing frame 3 and the second fixing frame 4 are connected to the support plate 1 and to the lower outer surface of the locomotive. The first fixing frame 3 and the support plate 1 form a first installation space, and the second fixing frame 4 and the support plate 1 form a second installation space. A blower cylinder 100 is installed in both the first and second installation spaces.
[0036] By moving the air cylinder 100 from its original internal mechanical compartment to the external traction transformer mounting structure, the air cylinder 100 is integrated with the traction transformer. This fully utilizes the external space of the locomotive and frees up the space previously occupied by the air cylinder 100 inside the locomotive, allowing for the placement of the power battery. This facilitates power battery placement without increasing the overall size of the locomotive, improving its lightweight design and operating efficiency. Furthermore, placing the air cylinder 100 externally facilitates its maintenance and reduces operational costs.
[0037] In some embodiments, a first support member 11 and a second support member 12 are fixedly disposed on the upper end surface of the support plate 1. The first support member 11 is located in a first installation space, and the second support member 12 is located in a second installation space. The first support member 11 and the second support member 12 are used to support the air cylinder 100. By setting the first support member 11 and the second support member 12, the air cylinder 100 can be effectively supported, ensuring the stability of the air cylinder 100 after installation. Specifically, the upper end surfaces of the first support member 11 and the second support member 12 can be designed as arc-shaped to better fit the shape of the air cylinder 100, thereby improving the stability of the support for the air cylinder 100. Moreover, a rubber or silicone buffer layer can be provided on the first support member 11 and the second support member 12 to play an elastic support role, thereby avoiding rigid contact between the air cylinder 100 and the first support member 11 and the second support member 12. At the same time, it can reduce the impact of vibration generated during locomotive operation on the air cylinder 100, ensuring that the air cylinder 100 can work normally and extending the service life of the air cylinder 100.
[0038] In some embodiments, a first positioning support 33 is fixedly installed on the side of the first fixed frame 3 facing away from the oil tank 2. By setting the first positioning support 33, the side wall of the air cylinder 100 can be supported and positioned, thereby facilitating the positioning and installation of the air cylinder 100. In order to improve the accuracy of positioning the air cylinder 100, the side of the first positioning support 33 facing the air cylinder 100 can be designed as arc-shaped, which can better fit the shape of the air cylinder 100, thereby improving the stability of the support for the air cylinder 100. Moreover, a rubber or silicone buffer layer can be set on the first positioning support 33 to play an elastic support role, thereby avoiding rigid contact between the air cylinder 100 and the first positioning support 33. At the same time, it can reduce the impact of vibration generated during locomotive operation on the air cylinder 100, ensure that the air cylinder 100 can work normally, and extend the service life of the air cylinder 100.
[0039] In some embodiments, a second positioning support 43 is fixedly installed on the side of the second fixing frame 4 opposite to the oil tank 2. By providing the second positioning support 43, the side wall of the air cylinder 100 can be supported and positioned, thereby facilitating the positioning and installation of the air cylinder 100. To improve the accuracy of positioning the air cylinder 100, the side of the second positioning support 43 facing the air cylinder 100 can be designed as an arc shape, which can better fit the shape of the air cylinder 100, thereby improving the stability of the support for the air cylinder 100. Moreover, a rubber or silicone buffer layer can be provided on the second positioning support 43 to provide elastic support, thereby avoiding rigid contact between the air cylinder 100 and the second positioning support 43. At the same time, it can reduce the impact of vibration generated during locomotive operation on the air cylinder 100, ensure that the air cylinder 100 can work normally, and extend the service life of the air cylinder 100.
[0040] In some embodiments, the first fixing frame 3 includes a first fixing part 32 and a first connecting part 31 connected to each other. The first connecting part 31 is connected to the side of the fuel tank 2 and the support plate 1. The first fixing part 32 extends in a first direction away from the fuel tank 2 and is connected to the lower outer surface of the locomotive. By connecting the first connecting part 31 to the fuel tank 2, and then by opening a first mounting hole in the first fixing part 32, and connecting it to the locomotive with bolts passing through the first mounting hole, the fuel tank 2 can be installed on the locomotive.
[0041] In some embodiments, the second fixing frame 4 includes a second fixing part 42 and a second connecting part 41 connected to each other. The second connecting part 41 is connected to the side of the fuel tank 2 and the support plate 1. The second fixing part 42 extends in a first direction away from the fuel tank 2 and is connected to the lower outer surface of the locomotive. By connecting the fuel tank 2 to the second connecting part 41 and then using the second fixing part 42, a second mounting hole is opened on the second fixing part 42, and bolts are passed through the second mounting hole to connect to the locomotive, thus installing the fuel tank 2 onto the locomotive. The use of the first fixing frame 3 and the second fixing frame 4 to fix the fuel tank 2 and the support plate 1 ensures the stability of the fixed installation.
[0042] In some embodiments, the tank 2 includes a tank body 21 and a tank cover 22, with the tank cover 22 covering the tank body 21. The tank cover 22 and the tank body 21 enclose an installation space for mounting the traction transformer body assembly. In this embodiment, the tank cover 22 is connected to the tank body 21 by bolts. By designing the tank cover 22 and the tank body 21 to be detachable, maintenance of the internal traction transformer body assembly is facilitated.
[0043] In some embodiments, reinforcing ribs 23 are provided on the sides of the box body 21 and / or the box cover 22. In this embodiment, reinforcing ribs 23 are provided on both the box cover 22 and the box body 21, which can improve the strength of the box cover 22 and the box body 21. Specifically, the reinforcing ribs 23 are cross ribs, which can further ensure the stability of the structure of the box cover 22 and the box body 21.
[0044] In some embodiments, an insulating oil cooling circulation pipe 5 is provided on the side of the oil tank 2. This arrangement facilitates connection with the insulating oil pipeline, thereby enabling the use of insulating oil to cool the traction transformer body and ensure stable operation of the traction transformer body.
[0045] This embodiment also provides a locomotive, which includes a locomotive body and the traction transformer mounting structure as described above. The traction transformer mounting structure is fixedly installed on the lower end of the outer side of the locomotive body, which facilitates the arrangement of the power battery without increasing the overall size of the locomotive, thereby improving the locomotive's lightweight level and increasing its operating efficiency.
