Technical Field

[0001] This utility model relates to the field of locomotive processing equipment technology, and in particular to a platform-based after-processing module for hybrid locomotives. Background Technology

[0002] As the European rail transport market increasingly demands environmental friendliness, economy, and flexibility, hybrid shunting locomotives, as a product that combines the advantages of both diesel and electric power, are gradually becoming the mainstream in the market. In existing technologies, traditional shunting locomotive designs mostly adopt a fixed structural layout, with high integration between various system components, making it difficult to achieve rapid function switching and flexible configuration. This results in a single platform being unable to adapt to the personalized needs of different customers.

[0003] Furthermore, as a key component of the internal combustion power system, the installation method of the aftertreatment system directly affects the heat insulation and vibration isolation performance of the entire vehicle. In traditional designs, the aftertreatment flue is usually rigidly connected to the vehicle body or module frame. The exhaust vibration of the diesel engine can easily be transmitted to the entire vehicle through the flue structure, affecting the stability of equipment operation and potentially causing structural fatigue problems.

[0004] Therefore, there is an urgent need to propose an after-processing module suitable for platform-based hybrid shunting locomotives, which can improve heat insulation, vibration isolation and adaptability. Utility Model Content

[0005] The purpose of this invention is to provide a platform-based after-treatment module for hybrid locomotives, which solves the technical problems of poor heat insulation and vibration isolation in existing processing modules.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] See Figures 1-2 This application provides a platform-based after-treatment module for hybrid locomotives, including a support frame 1; a pipeline assembly disposed on the support frame 1, one end of which is connected to a diesel engine turbocharger; a treatment component 2 disposed on the support frame 1, the other end of which is connected to the treatment component 2; a flue vibration isolation assembly 3 and a flue 4, wherein the flue 4 is elastically connected to the support frame 1 through the flue vibration isolation assembly 3.

[0041] In other words, the support frame 1 is made of high-strength materials to ensure its load-bearing capacity and stability, and to facilitate integration and disassembly with other locomotive components, thereby enabling flexible switching between different functional systems.

[0042] The piping assembly is mounted on the support frame 1, with one end connected to the diesel engine turbocharger via an interface to ensure the sealing and efficiency of exhaust gas transmission.

[0043] The flue vibration isolation component 3 is installed on the support frame 1 to support and fix the flue 4, and reduces vibration transmission through its elastic connection; the flue 4 forms an elastic connection with the support frame 1 through the flue vibration isolation component 3, which can effectively isolate the diesel engine exhaust vibration and reduce the impact of vibration on surrounding components.

[0044] This aftertreatment module adopts a modular design, with the support frame 1, pipeline assembly, treatment component 2, flue vibration isolation component 3, and flue 4 being independent and detachable from each other, facilitating flexible switching between different functional systems. The flue 4, through the flue vibration isolation component 3, forms an elastic connection with the support frame 1, which can effectively isolate diesel engine exhaust vibration, reduce the impact of vibration on surrounding components, and improve the stability and comfort of the locomotive. At the same time, the treatment component 2 also helps to reduce exhaust noise and improve the environmental performance of the locomotive.

[0045] Based on the above embodiments, see Figure 1 , Figure 2 and Figure 3 The piping assembly includes an exhaust bellows 5, which is connected to the outlet of the diesel engine turbocharger via a clamp; an exhaust pipe 6, which is connected to the exhaust bellows 5; an exhaust back pressure sensor interface 7, which is located at the outlet end of the processing unit 2; and an exhaust pipe bracket 8, which is used to fix the exhaust pipe 6 to the top of the support frame 1.

[0046] Specifically, the exhaust bellows 5 is made of a material that is resistant to high temperature and corrosion and has a certain degree of elasticity to adapt to the high temperature and vibration environment of diesel engine exhaust. One end of the exhaust bellows 5 is tightly connected to the outlet of the diesel engine turbocharger through a clamp to ensure the sealing and stability of exhaust gas transmission and prevent exhaust gas leakage.

[0047] The exhaust pipe 6 is connected to the other end of the exhaust bellows 5 and is used to transfer exhaust gas from the exhaust bellows 5 to the treatment unit 2. The exhaust pipe 6 is made of high-strength, high-temperature resistant material to ensure its stability and durability under high temperature and high pressure environment. The exhaust pipe 6 can be set as a multi-section structure as needed, and the sections are reliably connected by bolts and flanges to facilitate assembly and maintenance.

[0048] The exhaust back pressure sensor interface 7 is located at the outlet end of the treatment unit 2 and is used to connect the exhaust back pressure sensor to monitor and adjust the exhaust back pressure to ensure the normal operation of the aftertreatment module.

[0049] The exhaust pipe bracket 8 is used to fix the exhaust pipe 6 to the top of the support frame 1 to ensure the stability and reliability of the exhaust pipe 6. The exhaust pipe bracket 8 is made of high-strength material and has a support structure to withstand the weight and vibration of the exhaust pipe 6.

[0050] See Figure 1 , Figure 6 and Figure 7 Based on the above embodiments, the treatment component 2 is a silencer, which is made of steel plates spliced ​​and welded. It has a double channel inside and is provided with multiple reinforcing ribs to enhance the structural strength of the treatment component 2. It is fixed to the top of the support frame 1 by clamps, and the outer layer of the treatment component 2 is wrapped with heat insulation material.

[0051] Specifically, the silencer is made of high-quality steel plates spliced ​​and welded together, ensuring its high strength and durability, and enabling it to operate stably under high temperature and high pressure environments.

[0052] The muffler is designed with a dual-channel structure, which helps to improve the silencing effect and reduce the impact of exhaust noise on the surrounding environment and people. The muffler also has multiple reinforcing ribs inside, which not only enhance the structural strength of the muffler, but also reduce the risk of expansion and deformation caused by high temperature and other factors, thus improving the service life and stability of the muffler.

[0053] The muffler is fixed to the top of the support frame 1 by clamps, which is both stable and easy to disassemble and maintain, improving the flexibility and maintainability of the after-treatment module. The selection of clamps should take into account the compatibility with the muffler and the support frame 1 to ensure the firmness and sealing of the installation.

[0054] The outer layer of the muffler is wrapped with heat insulation material, which helps to reduce heat transfer, protect surrounding components from high temperatures, and improve the overall heat insulation performance of the locomotive. The selection of heat insulation material must take into account its high temperature resistance, heat insulation effect and durability to ensure stable heat insulation performance during long-term use.

[0055] Specifically, the processing component 2 can also be other components, which can be selected according to customer needs.

[0056] Based on the above embodiments, the support frame 1 is provided with an installation chamber, the processing component 2 is disposed in the installation chamber, the top of the installation chamber is provided with a ventilation and protective cover, and the installation chamber is composed of steel plates spliced ​​together.

[0057] In other words, the support frame 1, as the basic structure of the post-processing module, is made of high-strength materials to ensure its load-bearing capacity and stability. The support frame 1 contains a dedicated mounting chamber for installing the processing component 2 (silencer). The mounting chamber is composed of spliced ​​steel plates, which are fixed together by welding or bolts to ensure the strength and sealing of the mounting chamber. The size and shape of the mounting chamber are designed according to the size and shape of the processing component 2 to ensure that the processing component 2 can be accurately installed within the mounting chamber.

[0058] The top of the installation chamber is equipped with a ventilation and protective cover. The ventilation and protective cover not only serves an aesthetic and rainproof function, but also effectively removes the heat generated by the post-treatment equipment to the outside. The ventilation and protective cover ensures that while removing heat, it prevents rainwater from entering the installation chamber and affecting the normal operation of the treatment unit 2.

[0059] The ventilation cover is connected to the installation chamber by a sealing strip to ensure the airtightness of the installation chamber.

[0060] The treatment component 2 (silencer) is installed in the installation chamber and is securely mounted on the bottom or side wall of the installation chamber by clamps or other fixing methods; the outer layer of the treatment component 2 is wrapped with heat insulation material to reduce heat transfer and protect other components in the installation chamber from high temperature.

[0061] See Figure 4 , Figure 5 Based on the above embodiments, the flue vibration isolation assembly 3 includes a fixed bracket, which is fixed to the support frame 1 by bolts; and a vibration isolator, which is installed between the fixed bracket and the flue 4.

[0062] Specifically, the fixed support includes three basic supports, namely the first support 301, the second support 302 and the third support 303, which are welded to the support frame 1 respectively. The vibration isolator includes the first damper 304 and the second damper 305.

[0063] Two first shock absorbers 304 are bolted to the preset installation positions of the first bracket 301. A fourth bracket 306 is placed stably on top of the two first shock absorbers 304, ensuring that the fourth bracket 306 is in close contact with the first shock absorbers 304. Fifth brackets 307 are symmetrically installed on both sides of the fourth bracket 306. The fifth brackets 307 and the fourth bracket 306 are fixed by welding or bolting. At the same time, a sixth bracket 308 is installed at the bottom of the fifth bracket 307. The sixth bracket 308 is used to support the bottom of the flue 4.

[0064] The seventh bracket 309 is firmly fixed to the second bracket 302 and the third bracket 303 by bolts. Two second shock absorbers 305 are installed on the top of the seventh bracket 309 by bolts. The eighth bracket 310 is installed on the top of the second shock absorbers 305. During installation, the eighth bracket 310 is placed horizontally and in good contact with the second shock absorbers 305. The ninth bracket 311 is symmetrically installed on both sides of the eighth bracket 310. The ninth bracket 311 is connected to both sides of the flue 4 by bolts. Thus, the flue 4 is connected to the fixed bracket through four shock absorbers to achieve elastic support. The shock absorbers can absorb vibration. Compared with rigid support, this can ensure the service life of the steel structure and reduce the probability of resonance.

[0065] Based on the above embodiments, the flue 4 adopts an upward exhaust, and a protective cover is provided on its outer side, with a heat insulation layer between the protective cover and the flue 4.

[0066] Based on the above embodiments, the flue 4 adopts an upward exhaust configuration, which can effectively prevent high-temperature exhaust gas from blowing directly onto the overhead contact wire on the top of the locomotive, ensuring the safety of locomotive operation, and at the same time ensuring that the visibility of the cab crew is not affected.

[0067] The flue 4 is made of sheet metal welded together to ensure its structural strength and sealing, and to withstand the impact and emission pressure of high-temperature exhaust gas.

[0068] The outside of flue 4 is equipped with a protective cover, which is made of high-strength, high-temperature resistant material to protect flue 4 from damage by the external environment.

[0069] A heat insulation layer is provided between the protective cover and the flue 4. The heat insulation layer is made of high temperature resistant and heat insulation materials, such as ceramic fiber and aluminum silicate, to reduce heat transfer and protect the protective cover and surrounding components from high temperature.

[0070] The insulation layer not only improves the heat insulation performance of the post-processing module, but also reduces the risk of component expansion and deformation caused by high temperature, thereby improving the overall stability and durability of the post-processing module. Based on the above embodiments, the ventilation protective cover is a louvered structure and the protective cover is a double-layer stainless steel plate structure, thus ensuring the ventilation effect and guaranteeing the corresponding strength.

[0071] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0072] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
