Description

Technical Field

[0001] This utility model relates to the field of generator set technology, and in particular to a generator set with shock absorption function. Background Technology

[0002] Generator set vibration damping pads are devices specifically designed to reduce generator set vibration and noise, primarily reducing generator set vibration in the vertical direction.

[0003] However, existing generator sets are prone to bumps during transportation, which can cause the shock-absorbing pads to sway left and right or back and forth. This can cause the rubber of the shock-absorbing pads to be subjected to horizontal shear forces, leading to damage to the shock-absorbing pads and affecting the normal operation of the generator set. Utility Model Content

[0004] Therefore, there is a need to provide a generator set with shock absorption function to solve the technical problem that existing generator sets are prone to bumps during transportation, and the shock absorption pads are subjected to left-right or front-back shaking, which causes the rubber of the shock absorption pads to be subjected to horizontal shear force, resulting in the damage of the shock absorption pads and affecting the normal operation of the generator set.

[0005] To achieve the above objectives, this utility model provides a generator set with vibration damping function, comprising:

[0006] Chassis;

[0007] The power generation component is mounted on the chassis.

[0008] The vibration damping assembly includes a vibration damping pad, a vibration damping beam, and a vibration damping bracket. The vibration damping pad is installed on the chassis, the vibration damping beam is installed on the vibration damping pad along the width of the chassis, the power generation assembly is installed on the vibration damping beam, and a vibration damping bracket is installed at the front end and the rear end of the vibration damping beam.

[0009] Unlike existing technologies, the above technical solution installs a shock-absorbing beam between the power generation components and the shock-absorbing pad, and installs a shock-absorbing bracket at both the front and rear ends of the shock-absorbing beam. As a result, the shock-absorbing pad is not easily subjected to lateral and front-back forces during transportation, avoiding damage from shaking and vibration during transportation, thus not affecting the normal operation of the generator set.

[0010] As one embodiment of this utility model, the power generation component includes an engine and a generator, with the engine and generator connected together.

[0011] Two damping pads are installed at the engine and generator locations, spaced apart along the width of the chassis. Each damping pad corresponds to a damping beam and two damping brackets. The height of the two damping pads at the engine location along the height of the chassis is greater than the height of the two damping pads at the generator location along the height of the chassis.

[0012] In this way, by setting the height of the two damping pads at the engine location to be greater than the height of the two damping pads at the generator location along the chassis height direction, the taller damping pads can be adapted to the heavier load of the engine, while the shorter damping pads can be adapted to the lighter load of the generator.

[0013] In one embodiment of this utility model, the cross-section of the shock-absorbing beam at the engine is inverted U-shaped, and the cross-section of the shock-absorbing beam at the generator is U-shaped.

[0014] Thus, the cross-section of the damping beam at the engine is inverted U-shaped, with its opening facing downwards to cover the damping pad, enhancing torsional stiffness. Meanwhile, the cross-section of the damping beam at the generator is U-shaped, with its opening facing upwards to support the generator and lower the overall center of gravity. This differentiated height setting can match the center of gravity distribution of the power generation components, avoiding unbalanced loading.

[0015] As one embodiment of this utility model, the shock absorber bracket is L-shaped, with one side of the shock absorber bracket detachably connected to the chassis and the other side of the shock absorber bracket detachably connected to the shock absorber beam.

[0016] In this way, the two sides of the shock-absorbing bracket are detachably connected to the chassis and the shock-absorbing beam, respectively, so that the power generation components can use the shock-absorbing pads to filter vibrations along the height direction of the chassis during operation, thereby reducing unit vibration and noise.

[0017] As one embodiment of the present invention, the shock absorption assembly further includes a first shock absorption pad, which is installed on the other side of the shock absorption bracket between the shock absorption beam and the shock absorption bracket.

[0018] Thus, by setting the first damping pad to buffer high-frequency impacts, the transmission of high-frequency vibrations can be further attenuated.

[0019] As one embodiment of this utility model, the shock absorption assembly also includes a first fastener, mounting holes are provided at both ends of the shock absorption beam, and an oblong hole extending along the height direction of the chassis is provided on the other side of the shock absorption bracket, and the oblong hole and the mounting hole are connected by the first fastener.

[0020] Thus, by providing a waist-shaped hole extending along the height direction of the chassis, fine-tuning of the installation height can be achieved, eliminating assembly stress.

[0021] As one embodiment of this utility model, the shock-absorbing component also includes an inner nut. The shock-absorbing crossbeam has an inner nut welded to the inside of the mounting hole, and the inner nut is threadedly connected to the first fastener.

[0022] Thus, by welding an inner nut directly to the inside of the mounting hole, the first fastener can be prevented from loosening, ensuring the reliability of the rigid constraint during transportation.

[0023] As one embodiment of this utility model, the shock absorption assembly also includes a second fastener, and the shock absorption beam is installed between the power generation assembly and the shock absorption pad through the second fastener.

[0024] In this way, the power generation components, the shock-absorbing beam, and the shock-absorbing pad are locked together along the height of the chassis by the second fastener to prevent them from coming apart.

[0025] As one embodiment of the present invention, the shock absorption assembly further includes a second shock absorption pad extending along the width direction of the chassis, and the second shock absorption pad is installed between the power generation assembly and the shock absorption beam.

[0026] Thus, by installing a second damping pad extending along the width of the chassis between the power generation component and the damping beam, a secondary damping system is formed.

[0049] For ease of explanation, such as Figures 1 to 8 As shown, the direction of arrow Y is the width direction of the chassis, and the direction of arrow Z is the height direction of the chassis.

[0050] Existing generator sets are prone to bumps during transportation, which can cause the shock-absorbing pads to sway left and right or back and forth. This can result in the rubber of the shock-absorbing pads being subjected to horizontal shear forces, leading to damage to the shock-absorbing pads and affecting the normal operation of the generator set.

[0051] In view of this, this application provides a generator set 100 with vibration damping function, including a chassis 1, a power generation component 2 and a vibration damping component 3. The power generation component 2 is mounted on the chassis 1. The vibration damping component 3 includes a vibration damping pad 31, a vibration damping beam 32 and a vibration damping bracket 33. The vibration damping pad 31 is mounted on the chassis 1. The vibration damping beam 32 is mounted on the vibration damping pad 31 along the width direction Y of the chassis. The power generation component 2 is mounted on the vibration damping beam 32. A vibration damping bracket 33 is installed at the front end and the rear end of the vibration damping beam 32.

[0052] According to some embodiments of this application, please refer to Figures 1 to 8 This embodiment relates to a generator set 100 with vibration damping function, including a chassis 1, a power generation component 2, and a vibration damping component 3. The power generation component 2 is mounted on the chassis 1. The vibration damping component 3 includes a vibration damping pad 31, a vibration damping beam 32, and a vibration damping bracket 33. The vibration damping pad 31 is mounted on the chassis 1. The vibration damping beam 32 is mounted on the vibration damping pad 31 along the width direction Y of the chassis. The power generation component 2 is mounted on the vibration damping beam 32. A vibration damping bracket 33 is installed at the front end and the rear end of the vibration damping beam 32.

[0053] Chassis 1 is a steel frame that supports the entire machine. This is existing technology and will not be described further.

[0054] The generator set can be a diesel generator set, and therefore the engine 21 is a diesel engine 21. The generator set 2 also includes a radiator, which dissipates heat from the engine 21.

[0055] The vibration damping pad 31 is installed on top of the chassis 1 and is made of high-damping rubber material, which can absorb the vibration energy in the height direction Z of the chassis. The vibration damping beam 32 spans the top of the vibration damping pad 31 along the width direction Y of the chassis, forming a rigid force transmission frame. The vibration damping beam 32 evenly distributes the load of the power generation component 2 to the vibration damping pad 31, optimizing the vertical vibration damping efficiency. The vibration damping brackets 33 are respectively installed at the front and rear ends of the vibration damping beam 32. The symmetrical vibration damping brackets 33 form a horizontal force closed-loop constraint system, which converts the horizontal shear force generated by transportation bumps into the tensile and compressive forces of the vibration damping brackets 33, preventing the vibration damping pad 31 from being damaged by shear.

[0056] The above technical solution has a shock-absorbing beam 32 installed between the power generation component 2 and the shock-absorbing pad 31, and a shock-absorbing bracket 33 installed at both the front and rear ends of the shock-absorbing beam 32. As a result, the shock-absorbing pad 31 is not easily subjected to left and right and front and back forces during transportation, thus avoiding the shock-absorbing pad 31 being shaken and damaged during transportation, and thus not affecting the normal operation of the generator set.

[0057] like Figure 1 and Figure 2 As shown, the power generation assembly 2 includes an engine 21 and a generator 22, with the engine 21 connected to the generator 22. Two damping pads 31 are installed at intervals along the width direction Y of the chassis at both the engine 21 and the generator 22. The two damping pads 31 correspond to a damping beam 32 and two damping brackets 33. The height of the two damping pads 31 at the engine 21 along the height direction Z of the chassis is greater than the height of the two damping pads 31 at the generator 22 along the height direction Z of the chassis.

[0058] Two vibration damping pads 31 are installed at the engine 21. A vibration damping beam 32 is installed on top of the two vibration damping pads 31. A vibration damping bracket 33 is installed at both the front and rear ends of the vibration damping beam 32, and the two vibration damping brackets 33 are symmetrically arranged. Similarly, two vibration damping pads 31 are also installed at the generator 22. A vibration damping beam 32 is installed on top of the two vibration damping pads 31. A vibration damping bracket 33 is installed at both the front and rear ends of the vibration damping beam 32, and the two vibration damping brackets 33 are symmetrically arranged. Therefore, there are four vibration damping pads 31, two vibration damping beams 32, and four vibration damping brackets 33.

[0059] Thus, by setting the height of the two damping pads 31 at the engine 21 along the height direction Z of the chassis to be greater than the height of the two damping pads 31 at the generator 22 along the height direction Z of the chassis, the damping pads 31 with higher height can be adapted to the heavier load of the engine 21, and the damping pads 31 with lower height can be adapted to the lighter load of the generator 22.

[0060] like Figure 1 , Figures 4 to 8 As shown, the cross section of the damping beam 32 at the engine 21 is inverted U-shaped, and the cross section of the damping beam 32 at the generator 22 is U-shaped.

[0061] Thus, the cross-section of the damping beam 32 at the engine 21 is inverted U-shaped, with its opening facing downwards to cover the damping pad 31, enhancing torsional stiffness. Meanwhile, the cross-section of the damping beam 32 at the generator 22 is U-shaped, with its opening facing upwards to support the generator 22, lowering the overall center of gravity. Therefore, this differentiated height setting can match the center of gravity distribution of the power generation assembly 2, avoiding uneven loading.

[0062] like Figures 6 to 8As shown, the shock absorber bracket 33 is L-shaped. One side of the shock absorber bracket 33 is detachably connected to the chassis 1, and the other side of the shock absorber bracket 33 is detachably connected to the shock absorber beam 32.

[0063] When transporting the generator set 100 with shock absorption function: both ends of the shock absorption beam 32 and the shock absorption bracket 33 are locked, so the shock absorption pad 31 is not subjected to left and right or front and back forces, thus preventing the rubber of the shock absorption pad 31 from being shaken and damaged during transportation.

[0064] When the generator set 100 with vibration damping function is running: the vibration damping bracket 33 is detachable, and the vibration damping pad 31 filters vibration along the height direction Z of the chassis, reducing the vibration of the power generation component 2 and reducing noise.

[0065] Optionally, the corners of the L-shaped shock absorber bracket 33 are rounded to avoid stress concentration.

[0066] Thus, the two sides of the shock-absorbing bracket 33 are detachably connected to the chassis 1 and the shock-absorbing beam 32 respectively (such as by bolts, magnetic attraction or snap-fit), so that the power generation component 2 can filter the vibration left and right along the height direction Z of the chassis by the shock-absorbing pad 31 during operation, thereby reducing the vibration of the unit and reducing noise.

[0067] According to some embodiments of this application, optionally, the shock-absorbing assembly 3 further includes a first shock-absorbing pad, which is installed on the other side of the shock-absorbing bracket 33 between the shock-absorbing crossbeam 32.

[0068] The first damping pad can be made of rubber, which can effectively absorb vibrations.

[0069] Thus, by setting the first damping pad to buffer high-frequency impacts, the transmission of high-frequency vibrations can be further attenuated.

[0070] like Figure 5 and Figure 7 As shown, the shock absorption assembly 3 also includes a first fastener 34. The two ends of the shock absorption beam 32 are provided with mounting holes 321, and the other side of the shock absorption bracket 33 is provided with a waist-shaped hole 331 extending along the height direction Z of the chassis. The waist-shaped hole 331 and the mounting hole 321 are connected by the first fastener 34.

[0071] The first fastener 34 can be a bolt, screw, or stud, etc. In this embodiment, for example... Figure 7 As shown, one side of the shock absorber bracket 33 can be connected to the chassis 1 by bolts.

[0072] Thus, by providing a waist-shaped hole 331 extending along the height direction Z of the chassis, fine-tuning of the installation height can be allowed, eliminating assembly stress.

[0073] like Figure 8As shown, the shock-absorbing assembly 3 also includes an inner nut 35. The shock-absorbing crossbeam 32 has an inner nut 35 welded to the inside of the mounting hole 321. The inner nut 35 is threadedly connected to the first fastener 34.

[0074] Thus, by directly welding the inner nut 35 to the inside of the mounting hole 321, the first fastener 34 can be prevented from loosening, ensuring the reliability of the rigid constraint during transportation.

[0075] like Figure 3 As shown, the damping assembly 3 also includes a second fastener 36, and the damping beam 32 is installed between the power generation assembly 2 and the damping pad 31 via the second fastener 36.

[0076] The second fastener 36 can be a bolt, screw, or stud, etc. In this embodiment, a first hole is provided on the shock-absorbing crossbeam 32, and the second fastener 36 can be a high-strength bolt. Its head is tightly fitted with the shock-absorbing crossbeam 32, and the bolt shank passes through the power generation component 2 and the first hole and then engages with the corresponding screw hole on the shock-absorbing pad 31.

[0077] Thus, the power generation component 2, the shock-absorbing crossbeam 32, and the shock-absorbing pad 31 are locked together along the height direction Z of the chassis by the second fastener 36 to prevent them from coming apart.

[0078] According to some embodiments of this application, optionally, the shock absorption assembly 3 further includes a second shock absorption pad extending along the width direction Y of the chassis, the second shock absorption pad being installed between the power generation assembly 2 and the shock absorption beam 32.

[0079] The second damping pad can be made of rubber, which can effectively absorb vibrations.

[0080] Thus, by installing a second damping pad extending along the width direction Y of the chassis between the power generation component 2 and the damping beam 32, a secondary damping system is formed.

[0081] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of patent protection for this utility model.
