[0034] Please also read Figures 1 to 7 Now, the chassis structure for side installation of the generator set and the rail vehicle provided by the utility model are described. The chassis structure for side installation of the generator set includes a generator set installation module 1 and two sliding guide rails 2. The generator set installation module 1 is arranged above the vehicle body cross beam 61 and extends along the direction of the vehicle body. The generator set installation module 1 is used to support the generator set, and the generator set installation module 1 protrudes upward from the vehicle body floor 64; the two sliding guide rails 2 are respectively located at both ends of the generator set installation module 1, and each sliding guide rail 2 is connected between two longitudinal beams. The sliding guide rail 2 has a guide rail bar 21 that protrudes upward from the vehicle body floor 64 and extends to the side opening 63 of the vehicle body. The guide rail bar 21 can roll with the pulley of the generator set to guide the generator set to move above the generator set installation module 1.

[0035] Compared with the prior art, the chassis structure for side mounting of the generator set provided in the present embodiment utilizes the rolling cooperation between the sliding guide rail 2 and the pulley of the generator set to smoothly transfer the generator set to the unit mounting module 1, thereby improving the convenience of installing the generator set. The sliding guide rail 2 and the unit mounting module 1 are both arranged on the vehicle body cross beam 61, thereby avoiding local strength tolerance of the vehicle body floor 64, ensuring reliable installation quality, and improving the installation efficiency of the generator set.

[0036] In this embodiment, a vehicle body side opening 63 is provided on the side wall of the vehicle body, and the generator set is placed on the sliding track through the side opening 14. The generator set is pushed to roll along the sliding track to the unit installation module 1, and then the position of the generator set is fine-tuned to effectively align it with the installation position on the unit installation module 1. The generator set is manually tilted, the pulley under the generator set is retracted, and the generator set is installed and fixed on the unit installation module 1 to complete the installation operation. The above structure facilitates the rapid installation of the generator set using a forklift, and the operation process is simple and safe, which can effectively prevent the collision between the generator set and the vehicle body, and prevent the generator set or the vehicle body from being damaged by impact.

[0037] In some possible implementations, the above-mentioned characteristic unit installation module 1 adopts the following Figures 1 to 7 See the structure shown. Figures 1 to 7 The unit installation module 1 includes two installation beams 11 and an oil receiving pan 12. The two installation beams 11 are respectively arranged between the two sliding guide rails 2 along the direction of the vehicle body, and the two ends of each installation beam 11 are respectively connected to the two sliding guide rails 2 in a one-to-one manner; the oil receiving pan 12 is arranged between the two installation beams 11 and corresponds to the upper and lower parts of the generator set. The oil receiving pan 12 is gradually inclined downward from the periphery to the center, and an oil drain pipe 13 is connected to the bottom of the oil receiving pan 12.

[0038] In this embodiment, the oil receiving pan 12 is used to receive the oil falling from the generator set and discharge it downwards through the oil drain pipe 13. The mounting beams 11 are arranged on both sides of the oil receiving pan 12. The mounting beams 11 and the oil receiving pan 12 are assembled and assembled into a whole in advance and then installed on the vehicle body. The two ends of the mounting beam 11 are respectively connected to the adjacent side walls of the two sliding guide rails 2, and the bottom surface of the mounting beam 11 is connected to the top surface of the vehicle body cross beam 61. The connection is stable and reliable, which effectively avoids the local strength difference of the vehicle body floor 64 and helps to extend the life of the vehicle body bottom plate.

[0039] The middle part of the oil receiving pan 12 is tilted downward, which can effectively contain the oil and realize the effective collection of the oil, so as to facilitate the subsequent discharge of the oil through the oil drain pipe 13.

[0040] In some embodiments, the above-mentioned characteristic mounting beam 11 can be used as follows Figures 1 to 7 See the structure shown. Figures 1 to 7Side openings 14 are respectively provided on adjacent sides of the two mounting beams 11, and the opposite side edges of the oil receiving pan 12 are connected with guide bar seats 15 which are located in the side openings 14 and are arranged obliquely. The other two side edges of the oil receiving pan 12 are provided with support beams 16 connected between the two mounting beams 11.

[0041] In this embodiment, the mounting beam 11 installs the guide strip seat 15 through the side opening 14. The guide strip seat 15 and the support beam 16 are arranged around the outer periphery of the oil receiving pan 12, which can provide good structural support for the oil receiving pan 12 and ensure that the oil receiving pan 12 effectively receives the oil.

[0042] Specifically, the top surface of the guide bar seat 15 has the same inclination angle as the bottom wall of the oil receiving pan 12 , which can effectively guide the oil so that the oil can be easily discharged through the oil drain pipe 13 .

[0043] In some possible implementations, the above-mentioned characteristic mounting beam 11 is adopted as follows Figures 1 to 7 See the structure shown. Figures 1 to 7 A connecting hole 17 is provided on the top surface of the mounting beam 11, and a connecting seat 3 corresponding to the connecting hole 17 is connected to the inner top wall of the side opening 14. The mounting beam 11 and the generator set are connected by a connecting piece that passes through the connecting seat 3 and the connecting hole 17.

[0044] In this embodiment, the connection hole 17 on the top surface of the mounting beam 11 is used to connect to the bottom of the generator set through a connecting piece. By arranging a connecting seat 3 in the side opening 14 of the mounting beam 11, the structural strength of the connection position is greatly improved, thereby ensuring the reliable connection of the connecting piece to the mounting beam 11 and the generator set, and avoiding structural deformation caused by excessive force at a local position.

[0045] Specifically, a plurality of connection holes 17 are provided in the extension direction of the mounting beam 11, which correspond to the preset mounting holes on the generator set one by one, so that the connection parts can be conveniently passed through to achieve the effect of detachable connection.

[0046] In some embodiments, the above-mentioned characteristic connection seat 3 can be used as follows Figures 1 to 7 See the structure shown. Figures 1 to 7 The connecting seat 3 includes a connecting plate 31 and a U-shaped seat 32. The connecting plate 31 is connected to the inner top wall of the side opening 14; the U-shaped seat 32 is connected to the bottom of the connecting plate 31 and is opened upward. The connecting piece passes through the connecting plate 31 and the U-shaped seat 32.

[0047] In this embodiment, the connecting seat 3 is in the form of a combination of a connecting plate 31 and a U-shaped seat 32. The connecting plate 31 is attached to the inner top wall of the side opening 14, which can provide reliable structural reinforcement for the connection part of the mounting beam 11. The U-shaped seat 32 opens upward and is arranged below the connecting plate 31. The connecting piece passes through the mounting hole of the generator set, the top wall of the mounting beam 11, the connecting plate 31 and the bottom wall of the U-shaped seat 32 in sequence from top to bottom, and the lower end is fixed by a nut to ensure the reliability of the connection.

[0048] Specifically, a plurality of connection holes 17 are arranged at intervals in the extension direction of the mounting beam 11 , so that different positions of the generator set can be effectively connected to ensure the installation stability of the generator set.

[0049] In some possible implementations, the above-mentioned characteristic sliding guide rail 2 adopts the following Figures 1 to 7 See the structure shown. Figures 1 to 7 The sliding guide rail 2 is parallel to the vehicle body cross beam 61 and connected between two vehicle body longitudinal beams 62. The guide rail 21 has a rolling groove 22 which is opened upward and cooperates with the pulley of the generator set in a rolling manner.

[0050] In this embodiment, the sliding guide rail 2 extends perpendicular to the direction of the vehicle body, that is, is arranged parallel to the direction of the crossbeam, which can effectively limit and guide the moving direction of the generator set, thereby improving the smoothness of the movement of the generator set.

[0051] Specifically, the sliding guide rail 2 can adopt beams of different cross sections, such as B-beams, hat-shaped beams or square tube beams. The width of the rolling groove 22 arranged on the top surface of the guide rail 21 is adapted to the width of the pulley at the bottom of the generator set, which can form a guiding and limiting effect on the pulley, reducing the difficulty of installing the generator set.

[0052] In some embodiments, see Figures 1 to 7 The chassis structure for side installation of the generator set also includes a plurality of supporting beams 4 extending along the vehicle body and located below the unit installation module 1. The supporting beams 4 are connected between two adjacent vehicle body cross beams 61 or between adjacent vehicle body cross beams 61 and the sliding guide rail 2.

[0053] In this embodiment, a supporting beam 4 is additionally provided below the generator set. The supporting beam 4 is provided with multiple sections, and the two ends of the supporting beam 4 are respectively connected to two adjacent vehicle body cross beams 61, or the two ends of the supporting beam 4 are respectively connected to the adjacent vehicle body cross beam 61 and the sliding guide rail 2, so that the lower structure of the generator set is effectively strengthened and the stability of the structure is ensured.

[0054] In some possible implementations, the above-mentioned characteristic unit installation module 1 adopts the following Figures 1 to 7 See the structure shown. Figures 1 to 7Two groups of unit installation modules 1 are arranged at intervals along the direction of the vehicle body. The two groups of unit installation modules 1 are connected by a connecting beam 5 extending along the direction of the vehicle body. The bottom surface of the connecting beam 5 is connected to the top surface of the vehicle body cross beam 61.

[0055] In this embodiment, two sets of unit installation modules 1 are arranged in the installation area corresponding to the generator set. The two sets of unit installation modules 1 are arranged at intervals along the direction of the vehicle body and are connected by a connecting beam 5. The connecting beam 5 is arranged above the vehicle body cross beam 61. The two ends of the connecting beam 5 are respectively connected to the installation beams 11 of the two sets of unit installation modules 1, so that the two sets of unit installation modules 1 form a whole, thereby enhancing the supporting performance of the structure for the generator set.

[0056] In some embodiments, the above-mentioned characteristic connecting beam 5 can be adopted as follows Figures 1 to 7 See the structure shown. Figures 1 to 7 There are two connecting beams 5, and the two connecting beams 5 are respectively arranged in one-to-one correspondence with the two side edges of the unit installation module 1. The two connecting beams 5 connect the installation beams 11 of the two unit installation modules 1 and form an approximately rectangular structure, which ensures the stability of the structural support and improves the firmness of the generator set installation.

[0057] Installation process:

[0058] The generator set is placed on the sliding track through the side opening 14, and the generator set is pushed to roll along the sliding track to the unit installation module 1. Then, the position of the generator set is fine-tuned to effectively align it with the installation position on the unit installation module 1. The generator set is manually lifted and the pulley under the generator set is retracted. The generator set is installed and fixed on the unit installation module 1 to complete the installation operation.

[0059] Based on the same inventive concept, the embodiment of the present application also provides a rail vehicle, which includes a chassis structure for side installation of a generator set. The above vehicle uses a sliding guide rail 2 to roll with the pulley of the generator set, so that the generator set is smoothly transferred to the unit installation module 1, which improves the convenience of installing the generator set. The sliding guide rail 2 and the unit installation module 1 are both arranged on the vehicle body cross beam 61, which avoids the local strength of the vehicle body floor 64 from exceeding the tolerance, ensures reliable installation quality, and improves the installation efficiency of the generator set.
