For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0039] As shown in the background technology, in the related art, multiple hooks are used to suspend and support the generator set. The hook includes a connecting rod and a load-bearing hook connected to the connecting rod. The end of the connecting rod is connected to the bottom of the rail vehicle. The connecting rods and load-bearing hooks of the multiple hooks enclose an installation space. When the generator set is installed, the frame of the generator set is lifted to a level higher than the load-bearing hook, and the generator set is moved into the installation space by translation, and the frame of the generator set is connected to the load-bearing hook to support the generator set.

[0040] However, when the generator set is installed on the bottom of the rail vehicle, it is easy to collide with the hook, causing damage to the generator set or the hook.

[0041] In response to the above technical problems, an embodiment of the present application provides a generator set, comprising: a mounting frame, on which a connecting beam is provided; a generator set body, which is provided within the mounting frame; and a plurality of suspension mechanisms, wherein the suspension mechanisms include a hanger and a connector provided on the hanger, the hanger having a receiving cavity, the connecting beam being partially inserted into the receiving cavity and connected to the hanger, and the connector being used to connect to the bottom of a vehicle body. Compared with the prior art, the generator set of the embodiment of the present application does not require a protruding hook to be provided at the bottom of the vehicle body. The generator set can be directly lifted to the height of the bottom of the vehicle body and connected to the bottom of the vehicle body, thereby avoiding collision between the generator set and the hook or the vehicle body, thereby improving the safety and convenience of the generator set installation.

[0042] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0043] In the first aspect, the embodiment of the present application provides a generator set, combined with Figures 1 to 5 , including: an installation frame 100, and a connecting beam 110 is provided on the installation frame 100.

[0044] The generator set body 200 is disposed in the installation frame 100 .

[0045] Multiple suspension mechanisms 300, the suspension mechanisms 300 include a hanger 310 and a connector 320 arranged on the hanger 310, the hanger 310 has a receiving cavity 311, the connecting beam 110 is partially inserted into the receiving cavity 311 and connected to the hanger 310, and the connector 320 is used to connect to the bottom of the vehicle body.

[0046] It is understandable that, combined with Figure 7 As shown, in the prior art, a plurality of protruding hooks 600 are generally provided at the bottom of the vehicle body. The hooks 600 include a connecting rod 610 and a load-bearing hook 620, wherein one end of the connecting rod 610 is connected to the bottom of the vehicle body, and the other end is connected to the load-bearing hook 620. The load-bearing hook 620, the connecting rod 610, and the bottom wall of the vehicle body enclose an installation space 930, and the frame 700 of the engine unit is provided in the installation space and abuts against the load-bearing hook 620. However, since the hooks 600 are fixed to the bottom of the vehicle body, when installing the engine unit, it is necessary to first lift the engine unit to the horizontal height of the installation space and translate the frame 700 into the installation space. During the installation process, the generator unit is prone to collision with the hooks 600 or the bottom of the vehicle body, which can easily damage the generator unit or the vehicle body, resulting in poor safety.

[0047] Therefore, combined Figures 1 to 5 By setting a connecting beam 110 on the installation frame 100 supporting the generator set body 200, connecting the connecting beam 110 with the hanger 310, and setting a protruding connecting piece 320 on the hanger 310, the connecting piece 320 can be connected to the bottom of the vehicle body, so that the installation frame 100 supporting the generator set can be freely lifted to the connection between the connecting piece 320 and the bottom of the vehicle body for connection. Compared with the existing technology, there is no need to set a protruding hook at the bottom of the vehicle body. The generator set can be directly lifted to the height of the bottom of the vehicle body and connected to the bottom of the vehicle body, avoiding collision between the generator set and the hook or the vehicle body, thereby improving the safety and convenience of the generator set installation.

[0048] In addition, with such a setting, by adjusting the connection between the connector 320 and the bottom of the vehicle body, the space between the bottom of the vehicle body and the generator set can be fully utilized, so that the top of the generator set can fit with the bottom of the vehicle body, thereby increasing the distance between the bottom of the generator set and the ground, which is convenient for heat dissipation.

[0049] Among them, in one possible embodiment, combined with Figure 2 、 Figure 4 and Figure 5 As shown, the suspension mechanism 300 further includes a first vibration isolator 330 and a pulling rope 340 .

[0050] The connecting beam 110 is connected to the suspension base 310 via a first vibration isolator 330 .

[0051] One end of the pulling rope 340 is connected to the connecting beam 110 , and the other end of the pulling rope 340 is used to be connected to the bottom of the vehicle body.

[0052] It is understandable that the generator set body 200 will generate vibration when working. The generator set body 200 is set in the installation frame 100, so the vibration force will be transmitted to the vehicle body through the installation frame 100, causing vibration impact on the vehicle body. Therefore, a first vibration isolator 330 can be set at the connection between the installation frame 100 and the vehicle body, and the first vibration isolator 330 is used to absorb the vibration force transmitted from the installation frame 100 to the vehicle body.

[0053] Specific, combined Figure 2 、 Figure 4 and Figure 5 As shown, the first vibration isolator 330 is connected to the connecting beam 110 inserted into the accommodating cavity 311, and the first vibration isolator 330 has a protrusion 331, which extends into the accommodating cavity 311 of the hanger 310 and is connected to the hanger 310, so that the connecting beam 110 and the hanger 310 are connected through the first vibration isolator 330. The first vibration isolator 330 has an elastic part (not shown in the figure), which can absorb vibration transmitted to the vehicle body.

[0054] It is understandable that after the generator set is installed on the vehicle body, in order to prevent the generator set from falling directly when the connection between the connector 320 and the vehicle body is disconnected or the generator set needs to be disassembled for maintenance, an anti-detachment structure can be set on the generator set.

[0055] Specifically, refer to Figure 4 and Figure 5 As shown, a lifting ear 510 is provided on the bottom beam 500 (to be introduced below) at the bottom of the vehicle body, one end of the pulling rope 340 is connected to the lifting ear 510, and the other end of the pulling rope 340 is connected to the connecting beam 110. The natural length of the pulling rope 340 can be greater than the vibration amplitude of the connecting beam 110, and the natural length of the pulling rope 340 is less than the height from the connecting beam 110 to the ground, that is, when the generator set is working normally, the pulling rope 340 is in a natural hanging state and will not be subjected to force; when the connecting beam 110 is detached from the vehicle body, the pulling rope 340 can pull the connecting beam 110 and can prevent the generator set body 200 from falling directly to the ground, thereby improving safety.

[0056] Among them, in one possible embodiment, combined with Figure 3 、 Figure 4 and Figure 5 As shown, the connecting member 320 is connected to the vehicle body via a fastener 400 .

[0057] Reference Figure 3 、 Figure 4 and Figure 5 As shown, one end of the connector 320 is connected to the hanger 310, and the other end of the connector is inserted into the vehicle body and connected via a fastener 400 to suspend the generator set from the bottom of the vehicle body. The connector 320 can be a screw, and the fastener 400 can be a nut, and the connector 320 and the fastener 400 are threadedly connected.

[0058] Among them, in a possible implementation manner, as Figure 1 As shown, the generator set body 200 includes a generator 210, a diesel engine 220, a cooling device 230 and an auxiliary device 240. There is an installation space in the installation frame 100. The generator 210, the diesel engine 220 and the cooling device 230 are installed in the installation space in sequence along the extension direction of the installation frame 100. The auxiliary device 240 is connected to the outer periphery of the installation frame 100.

[0059] Specifically, refer to Figure 1 As shown, the generator 210, the diesel engine 220 and the cooling device 230 are interconnected and installed in the installation space along the extension direction of the installation frame 100. The auxiliary device 240 includes a silencer, a filter and other structures, which can be connected to the outer periphery of the installation frame 100 to reduce the height space of the generator set body 200 for compact installation and reduce the space occupied by the generator set. When the distance between the bottom of the vehicle body and the ground remains unchanged, a larger large-power generator set body 200 can be used and the generator set can be installed to the bottom of the vehicle body.

[0060] Further, combined Figure 1 and Figure 6 As shown, the cooling device 230 includes a fan 231 and a first heat sink 232 attached to the fan 231 .

[0061] The first radiator 232 has a first air inlet 2321 and a first air outlet 2322 . The diesel engine 220 includes a supercharger and an air inlet. The first air inlet 2321 is connected to the supercharger through a pipe 234 , and the first air outlet 2322 is connected to the air inlet through a pipe 234 .

[0062] The fan 231 is used to dissipate heat from the first radiator 232 .

[0063] Specific, combined Figure 1 and Figure 6As shown, the supercharger of the diesel engine 220 is connected to the first air inlet 2321 of the first radiator 232 through a pipe 234, and the first air outlet 2322 of the first radiator 232 is connected to the air inlet of the diesel engine 220, forming a supercharged air circulation loop, thereby delivering the high-temperature compressed air supercharged after the diesel engine 220 is working to the first radiator 232, and utilizing the first radiator 232 for heat exchange. After the heat exchange is completed, the cooled gas is delivered back to the diesel engine 220 through the first air outlet 2322 to cool the diesel engine 220.

[0064] The fan blades of the fan 231 sweep an area toward the first radiator 232 so that the high-temperature compressed air can be heat exchanged.

[0065] Among them, combined Figure 1 and Figure 6 As shown, the cooling device 230 also includes a second radiator 233, which is attached to the side of the first radiator 232 away from the fan 231. The second radiator 233 has a second water inlet 2331 and a second water outlet 2332. The second water inlet 2331 and the second water outlet 2332 are respectively connected to the water tank of the diesel engine 220 through a water pipe 235 to form a water cooling circulation loop.

[0066] The fan 231 is used to dissipate heat from the second radiator 233 .

[0067] It is understandable that the diesel engine 220 can be a water-cooled diesel engine. In order to avoid the water in the water tank being in a continuously high temperature state during operation, which affects the performance of the diesel engine 220, a second radiator 233 can be set to further cool the diesel engine 220 to enhance the cooling effect.

[0068] Specific, combined Figure 1 and Figure 6 As shown, the water outlet of the water tank of the diesel engine 220 is connected to the second water inlet 2331 of the second radiator 233 through a water pipe 235, and the second water outlet 2332 of the second radiator 233 is connected to the water inlet of the water tank of the diesel engine 220 through the water pipe 235, forming a cooling water circulation loop. The second radiator 233 is used to exchange heat with the water in the diesel engine 220, and the cooling water is transported back to the diesel engine 220 to cool the diesel engine 220.

[0069] In addition, the fan blade sweep area of ​​the fan 231 also blows air toward the second radiator 233 to dissipate heat from the second radiator 233. Figure 6As shown, the second radiator 233 is attached to the side of the first radiator 232 away from the fan 231, so that the same fan 231 can dissipate heat for the first radiator 232 and the second radiator 233, reducing the number of fans 231, thereby reducing the size and weight of the generator set body 200, so as to install a high-power generator 210.

[0070] It should be noted that the speed of the fan 231 is controlled by a controller (not shown in the figure), and the speed of the fan 231 can be adjusted according to the water temperature of the diesel engine 220 and the temperature of the supercharged air to improve the cooling efficiency and reduce the heat dissipation power consumption and the noise of the fan 231.

[0071] Specifically, the initial temperature t1 and the limit temperature t2 of the cooling water can be set according to the actual application environment. When the water temperature of the diesel engine 220 is lower than t1, there is no need to continue cooling, and the controller controls the fan 231 not to rotate or to maintain a low speed; when the water temperature of the diesel engine 220 is higher than t1, the controller controls the fan 231 to gradually increase its speed as the water temperature rises; when the water temperature of the diesel engine 220 rises to t2, the controller controls the fan 231 to increase its speed to the maximum speed to avoid damage caused by excessive temperature of the diesel engine 220.

[0072] Similarly, the initial temperature t3 and the limit temperature t4 of the supercharged air can be set according to the actual application environment. When the supercharged air of the diesel engine 220 is lower than t3, there is no need to continue cooling, and the controller controls the fan 231 not to rotate or to maintain a low speed; when the supercharged air of the diesel engine 220 is higher than t3, the controller controls the fan 231 to gradually increase its speed as the supercharged air temperature rises; when the water temperature of the diesel engine 220 rises to t4, the controller controls the fan 231 to increase its speed to the maximum speed to avoid damage to the diesel engine 220 due to excessive temperature.

[0073] In addition, it should be noted that when the generator set body 200 is damaged, the controller controls the fan 231 to always maintain the highest speed to ensure the safety of the generator set.

[0074] In one possible implementation, the installation direction of the generator set body 200 is perpendicular to the running direction of the vehicle body.

[0075] It is understood that when the generator set is suspended from the underside of the vehicle, the generator set body 200 is installed perpendicular to the vehicle's operating direction, meaning it is installed along the width of the vehicle. During vehicle operation, along the direction in which the generator set body 200 is installed, the generator 210 on one side of the vehicle absorbs some of the cool air. After exchanging heat with the generator 210, the air is then discharged to the sides, blocked by vertical side panels 130 (described below), preventing the hot air from reaching the diesel engine 220. Another portion of the air is drawn into the auxiliary device 240, participating in the combustion and operation of the diesel engine 220 and being consumed. A large amount of cool air from the environment is drawn into the fan 231 of the cooling device 230, exchanging heat with the first radiator 232 and the second radiator 233, before being discharged to the atmosphere through the other side of the vehicle. Furthermore, the air blown by the fan 231 accelerates air circulation under the vehicle, reducing heat accumulation and minimizing the thermal impact of the generator set on other under-vehicle equipment.

[0076] This arrangement allows the hot air generated after the heat exchange between the cold air and the generator set body 200 to be discharged from different directions, avoiding the high temperature effect of the generator set caused by the backflow of cold and hot air.

[0077] Among them, in one possible embodiment, combined with Figure 1 and Figure 2 As shown, the mounting frame 100 includes a base plate 120 and a plurality of vertical side plates 130. The plurality of vertical side plates 130 are vertically connected to the base plate 120. The vertical side plates 130 and the base plate 120 enclose an installation space, and adjacent vertical side plates 130 are spaced apart along the extension direction of the base plate 120, dividing the installation space into a generator installation area for installing the generator 210, a diesel engine installation area for installing the diesel engine 220, and a cooling device installation area for installing the cooling device 230.

[0078] Specifically, such as Figure 1 and Figure 2 As shown, multiple vertical side panels 130 can be welded perpendicularly to the bottom plate 120. The vertical side panels 130 and the bottom plate 120 enclose an installation space. The bottom plate 120 is used to support the generator set body 200. The multiple vertical side panels 130 are parallel to each other and are spaced apart along the extension direction of the bottom plate 120, thereby dividing the installation space into multiple installation areas. Each installation area can respectively correspond to the installation of a generator 210, a diesel engine 220 and a cooling device 230.

[0079] It should be noted that the base plate 120 can be a complete steel plate, or it can be formed by splicing and welding partial steel plates in different installation areas. The steel plate surfaces of each installation area are respectively adapted to the generator 210, the diesel engine 220 and the cooling device 230 to ensure the installation strength and avoid displacement of the generator set body 200 due to vibration after startup.

[0080] Further, such as Figure 2 As shown, a plurality of second vibration isolators 140 are provided on the bottom plate 120 , and the plurality of second vibration isolators 140 are evenly arranged in the generator installation area, the diesel engine installation area and the cooling device installation area.

[0081] It is understandable that, referring to Figure 2 As shown, the generator set body 200 will generate vibrations during operation. Therefore, a plurality of second vibration isolators 140 can be evenly arranged in the generator installation area, the diesel engine installation area and the cooling device installation area where the generator set body 200 is installed. The second vibration isolators 140 are used to absorb the vibration force transmitted from the generator set body 200 to the installation frame 100, thereby reducing the vibration and noise generated after the generator set body 200 is started, and further enhancing the vibration reduction effect.

[0082] It should be noted that the second vibration isolator 140 can be provided in a dish or disc shape, which not only has a good vibration isolation and noise reduction effect, but also occupies a small space, thereby reducing the overall height of the generator set and achieving compact installation.

[0083] In the second aspect, the embodiment of the present application provides a rail vehicle, Figure 1 and Figure 3 As shown, it includes a vehicle body and the generator set provided by the first aspect.

[0084] The vehicle body includes a vehicle body and a bottom beam 500 arranged at the bottom of the vehicle body. A connecting hole is opened on the bottom beam 500, and the connecting member 320 of the generator set passes through the connecting hole to be connected to the bottom beam 500.

[0085] It is understandable that, combined with Figure 1 and Figure 3 As shown, the bottom beam 500 is arranged at the bottom of the vehicle body, wherein a connecting hole can be opened on the bottom beam 500, and the connecting hole is adapted to the connecting member 320 of the generator set. When installing the generator set, the generator set can be lifted, the connecting member 320 can be passed through the connecting hole, and fixed with the fastener 400, so that the connecting member 320 is connected to the bottom beam 500, thereby completing the hoisting of the generator set.
