Description

Technical Field

[0001] This application relates to the technical field of generator set frames, and in particular to a shock-absorbing frame for generator set installation. Background Technology

[0002] A generator set is a complete set of mechanical equipment that converts other forms of energy (such as diesel, natural gas, etc.) into electrical energy. It is widely used in industrial, commercial, civil, and emergency power supply fields. During operation, the piston of the diesel engine or motor inside the generator set reciprocates, and the crankshaft rotates at high speed. These movements generate periodic excitation forces, causing the entire unit to produce continuous mechanical vibration.

[0003] To reduce the impact of vibration on the generator set and its surrounding environment, generator sets are typically mounted on a foundation using vibration damping frames. The function of the vibration damping frames is to absorb and buffer the vibration energy generated during generator operation, protect the precision components inside the unit, extend the service life of the equipment, and reduce noise.

[0004] Currently, common generator set vibration damping frames mainly adopt structural forms such as spring damping, rubber damping, or airbag damping. For example, Chinese utility model patent CN217874940U discloses a vibration damping frame for generator set installation, which includes a base plate, a protective frame, a sliding plate, a movable plate, springs, and a buffer mechanism. The generator set is fixedly connected to the mounting plate by bolts passing through positioning holes in the mounting plate. A vibration damping structure consisting of positioning columns and springs is provided below the mounting plate, as well as a buffer mechanism consisting of large and small airbags. When the generator set floats up and down, the double buffering effect of the springs and airbags achieves a vibration damping effect.

[0005] However, the vibrations generated by the generator set during operation are continuous and high-frequency. Although the vibration damping frame can absorb some of the vibration energy, the vibrations will still be transmitted to the bolt connections between the mounting plate and the generator set. Under long-term, high-frequency vibration, these bolt connections are prone to loosening. Therefore, regular maintenance and inspections are necessary. Due to the continuous vibration during the inspection cycle, the bolts may loosen between inspections, posing a safety hazard. Summary of the Invention

[0006] The technical solution adopted in this application is as follows: A vibration damping frame for mounting a generator set includes a frame, a mounting plate disposed on the frame, and a locking mechanism for connecting the generator set to the mounting plate. The locking mechanism includes a locking component and an anti-detachment component. The mounting plate has a mounting hole. The anti-detachment component includes an anti-detachment sleeve and an abutment ring disposed at the end of the anti-detachment sleeve. The anti-detachment sleeve can pass through the generator set and be inserted into the mounting hole. A positioning structure is provided between the anti-detachment sleeve and the mounting hole to prevent the anti-detachment sleeve from coming out of the mounting hole. The locking component includes a bolt passing through the anti-detachment sleeve and a locking block threaded to the bolt. The locking block abuts against the underside of the mounting plate. The end of the bolt can abut against the abutment ring so that the abutment ring abuts against the generator set, and at the same time can drive the positioning structure to connect the anti-detachment sleeve and the mounting plate together.

[0007] By adopting the above technical solution, when the generator set is installed on the mounting plate, the anti-detachment sleeve passes through the generator set and is inserted into the mounting hole. Then, the bolt passes through the anti-detachment sleeve, and the locking block is threadedly connected to the bolt, so that the head of the bolt abuts against the abutment ring, driving the abutment ring to abut against the surface of the generator set. The locking block then abuts against the lower surface of the mounting plate, thereby fixing the generator set to the mounting plate. In this process, the positioning structure can connect the anti-detachment sleeve and the mounting plate together. When the locking block loosens, the anti-detachment sleeve can still connect the anti-detachment sleeve and the mounting plate together, thus maintaining the positioning effect of the generator set.

[0008] Optionally, the positioning structure includes a positioning block fixed to the side wall of the anti-detachment cylinder and a sliding block slidably disposed on the side wall of the anti-detachment cylinder. The sliding block can slide along the circumferential direction of the anti-detachment cylinder. A slot is formed in the inner wall of the mounting hole, and the slot corresponds to the positioning block and the sliding block. An annular groove is formed in the inner wall of the mounting hole, and the end of the slot is connected to the annular groove. When the bolt passes through the anti-detachment cylinder and is locked by the locking block, the positioning block and the sliding block are located in the annular groove, and the sliding block can slide along the circumferential direction of the anti-detachment cylinder so that the sliding block and the slot are offset.

[0009] By adopting the above technical solution, when the anti-detachment block is inserted into the mounting hole, the positioning block and the sliding block slide into the slot respectively, and finally enter the annular groove. When the bolt is tightened, the sliding block is driven to slide, so that the sliding block and the slot can be misaligned. Therefore, the anti-detachment cylinder can no longer be pulled out of the mounting hole, thus maintaining the positioning effect on the generator set.

[0010] Optionally, the anti-detachment sleeve has an installation groove that extends circumferentially along the anti-detachment sleeve. A connecting seat is slidably disposed in the installation groove. An elastic element is disposed between the connecting seat and the installation groove. The side wall of the anti-detachment sleeve has a clearance groove that communicates with the installation groove. The sliding block passes through the clearance groove and connects with the connecting seat. The anti-detachment sleeve is provided with a trigger element. When the end of the bolt is pressed against the abutment edge, the connecting seat can be driven to slide through the trigger element.

[0011] By adopting the above technical solution, after the trigger drives the connecting seat to slide, it can drive the sliding block to slide, thereby achieving the effect of the sliding block and the slot being staggered.

[0012] Optionally, the anti-detachment cylinder is provided with a insertion groove, which extends along the axial direction of the anti-detachment cylinder and communicates with the mounting groove. The triggering element includes a trigger rod that is slidably inserted into the insertion groove. The trigger rod can be pressed against the end of the bolt and slide into the insertion groove, and can abut against the end of the connecting seat and push the connecting seat to slide.

[0013] By adopting the above technical solution, when the trigger rod slides in the insertion slot, it can abut against the connector, thereby driving the connector to slide.

[0014] Optionally, the end of the trigger rod is provided with an abutment ring, and a guide rod is provided on the abutment ring, the guide rod being slidably inserted into the anti-detachment cylinder.

[0015] By adopting the above technical solution, the sliding of the trigger rod is more stable under the action of the guide rod.

[0016] Optionally, the lower surface of the mounting plate is provided with an extension seat, the mounting hole extends to the end of the extension seat away from the mounting plate, and the locking block abuts against the lower end of the extension seat.

[0017] By adopting the above technical solution, the depth of the mounting hole can be increased by extending the seat, which is more conducive to the stability of the overall structure.

[0018] Optionally, the side wall of the trigger rod is provided with a reset member, the anti-detachment cylinder has a receiving groove, and the reset member is located in the receiving groove. When the trigger rod is pressed and slides into the insertion groove, the reset member is in the initial state.

[0019] By adopting the above technical solution, the trigger rod is less likely to slip out of the insertion slot under the action of the reset component, thereby improving the positioning effect of the anti-detachment cylinder.

[0020] Optionally, the end of the anti-detachment cylinder is provided with a storage groove, and the abutment ring can abut against the storage groove.

[0021] Optionally, there are two mounting slots, and the two mounting slots are connected. The plug slot is located at the position where the two mounting slots are connected. Each mounting slot is equipped with a connector. The trigger rod can slide to drive the two connectors to slide.

[0022] By adopting the above technical solution, two connecting seats are provided, so that the two sliding blocks and the positioning block form three positioning points, which makes it more difficult for the anti-detachment cylinder to come out of the mounting hole.

[0023] In summary, this application includes at least one of the following beneficial effects: 1. During the positioning of the generator set, the anti-detachment sleeve connects the generator set and the mounting plate together, and the bolt locking block also positions the generator set on the mounting plate. When the locking block loosens, the sliding block and the positioning block remain in the annular groove, making it difficult for the anti-detachment sleeve to come out of the mounting hole, thus maintaining the positioning effect of the generator set.

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] This application discloses a shock-absorbing frame for generator set installation, referring to... Figure 1 and Figure 2The device includes a frame 1, a mounting plate 2 disposed on the frame 1, and a locking mechanism 3 for connecting the generator set to the mounting plate 2. A shock-absorbing structure is provided between the mounting plate 2 and the frame 1 to absorb the vibration generated during the operation of the generator set. The specific structure of this structure is prior art and is not the focus of this application, so it will not be described in detail here.

[0028] Reference Figure 2 and Figure 3 The mounting plate 2 is used to support the generator set. The mounting plate 2 has multiple mounting holes 6, which correspond to the through holes on the base of the generator set. They are used to cooperate with the locking mechanism 3 to fix the generator set on the mounting plate 2.

[0029] Reference Figure 2 and Figure 4 The locking mechanism 3 includes a locking assembly 5 and an anti-detachment assembly 4. The anti-detachment assembly 4 includes an anti-detachment cylinder 41 and an abutment ring 42 disposed at the end of the anti-detachment cylinder 41. The anti-detachment cylinder 41 is a cylindrical component, combined with... Figure 3 Its outer diameter matches the inner diameter of the mounting hole 6, allowing it to pass sequentially from top to bottom through the through hole on the generator set base and the mounting hole 6 on the mounting plate 2. The abutment ring 42 is located at the upper end of the anti-detachment cylinder 41, and the outer diameter of the abutment ring 42 is larger than the outer diameter of the anti-detachment cylinder 41, for abutting against the upper surface of the generator set base.

[0030] Reference Figure 3 and Figure 4 A positioning structure 7 is provided between the anti-detachment sleeve 41 and the mounting hole 6. This positioning structure 7 is used to prevent the anti-detachment sleeve 41 from detaching upward from the mounting hole 6. Specifically, the positioning structure 7 includes a positioning block 71 fixed to the side wall of the anti-detachment sleeve 41 and a sliding block 72 slidably disposed on the side wall of the anti-detachment sleeve 41. The sliding block 72 can slide along the circumferential direction of the anti-detachment sleeve 41. The inner wall of the mounting hole 6 is provided with slots 8, the number and position of which correspond to the positioning block 71 and the sliding block 72. The inner wall of the mounting hole 6 is also provided with an annular groove 9, which is located at the lower end of the slot 8 and communicates with the end of the slot 8. The slot 8 extends vertically, and the annular groove 9 extends circumferentially.

[0031] When the anti-detachment sleeve 41 is inserted into the mounting hole 6, the sliding block 72 and the positioning block 71 slide into the slot 8. The locking assembly 5 includes a bolt 51 and a locking block 52. The bolt 51 passes through the inner cavity of the anti-detachment sleeve 41, with its head located on the outer side of the upper end of the anti-detachment sleeve 41, and its shank extending downward and exiting from the lower end of the anti-detachment sleeve 41. The locking block 52 is threaded to the lower end of the bolt 51 and is located below the mounting plate 2. An extension seat 18 is provided on the lower surface of the mounting plate 2, and the mounting hole 6 extends to the lower end face of the extension seat 18. The locking block 52 abuts against the lower end face of the extension seat 18, and the head of the bolt 51 abuts against the abutment ring 42, thereby locking and fixing the generator set to the mounting plate 2. The end of the extension seat 18 has a rough structure to reduce the possibility of the locking block 52 loosening.

[0032] Reference Figure 4 and Figure 5 The anti-detachment cylinder 41 has a mounting groove 10 on its side wall, which extends a certain arc length along the circumference of the anti-detachment cylinder 41. A connecting seat 11 is slidably disposed in the mounting groove 10, and an elastic element 12 is disposed between the connecting seat 11 and the mounting groove 10. The elastic element 12 is a spring, one end of which abuts against the connecting seat 11, and the other end is connected to the end wall of the mounting groove 10, always applying a force in one direction to the connecting seat 11. The anti-detachment cylinder 41 also has a clearance groove 13 that communicates with the mounting groove 10 on its side wall. The sliding block 72 passes through the clearance groove 13 and is fixedly connected to the connecting seat 11, so that the sliding block 72 can move synchronously with the connecting seat 11. When the connecting seat 11 slides in the mounting groove 10, the sliding block 72 slides circumferentially on the outer side wall surface of the anti-detachment cylinder 41. Furthermore, a hole can be made in the inner wall of the through hole on the generator set base for the sliding block 72 and the positioning block 71 to pass through, so that the anti-detachment cylinder 41 can pass through the generator set base. In other embodiments, the anti-detachment cylinder 41 can be passed through the base of the generator set and then the sliding block 72 and the positioning block 71 can be fixed on.

[0033] A trigger element 14 is provided on the anti-detachment cylinder 41 for driving the connecting seat 11 to slide. The trigger element 14 includes a trigger rod 141. The anti-detachment cylinder 41 has an insertion groove 15, which extends along the axial direction of the anti-detachment cylinder 41 and communicates with the mounting groove 10. The trigger rod 141 is slidably inserted into the insertion groove 15, with the upper end of the trigger rod 141 protruding from the top of the anti-detachment cylinder 41 and the lower end extending into the mounting groove 10. When the trigger rod 141 is pushed by the head of the bolt 51, the end of the trigger rod 141 can abut against the end of the connecting seat 11 and push the connecting seat 11 to slide along the mounting groove 10, thereby driving the sliding block 72 to move. The sliding block 72 can then enter the annular groove 9, causing the sliding block 72 and the slot 8 to be misaligned. Therefore, the anti-detachment block is not easy to come out of the mounting hole 6. To facilitate the sliding of the connecting seat 11, a block is fixed at the lower end of the trigger rod 141, and the insertion slot 15 has an enlarged diameter portion to provide space for the block to move.

[0034] Reference Figure 5 and Figure 6 The trigger rod 141 has an abutment ring 16 at its end, which engages with the head of the bolt 51. A guide rod 17 is also provided on the abutment ring 16, which slides vertically into the upper end of the anti-detachment cylinder 41 to ensure the stability of the trigger rod 141 during vertical sliding. An annular receiving groove 21 is provided at the end of the anti-detachment cylinder 41, allowing the abutment ring 16 to fall into the receiving groove 21 when the trigger rod 141 slides downwards, making the overall structure more compact.

[0035] Reference Figure 5 and Figure 6 To maintain the position of the trigger rod 141 after it slides, a reset member 19 is provided on the side wall of the trigger rod 141. A receiving groove 20 is provided at the corresponding position of the anti-detachment cylinder 41, and the reset member 19 is located in the receiving groove 20. The reset member 19 is a spring and is connected between the receiving groove 20 and the trigger rod 141. When the trigger rod 141 is pressed into the insertion groove 15, the reset member 19 is in its initial state (i.e., not compressed or stretched). When the trigger rod 141 needs to be reset upwards, the reset member 19 provides a restoring force. Under the action of the reset member 19, the bolt 51 loosens, and the trigger rod 141 is less likely to slide out of the insertion groove 15.

[0036] Furthermore, in this embodiment, two mounting slots 10 are provided, which are symmetrically arranged around the anti-detachment cylinder 41 and connected to each other. The insertion slot 15 is located at the connection point of the two mounting slots 10, that is, the connecting seat 11 is symmetrically located on both sides of the trigger rod 141. The lower end of the trigger rod 141 is wedge-shaped, allowing it to simultaneously abut the ends of the two connecting seats 11. Each mounting slot 10 is equipped with a connecting seat 11 and a sliding block 72, thus forming two slidable sliding blocks 72. Combined with the fixed positioning block 71, this forms three circumferentially distributed positioning points, making the anti-detachment cylinder 41 more stable in the mounting hole 6 and less prone to detachment.

[0037] The working principle of this embodiment is as follows: When installing the generator set, the through hole on the generator set base is aligned with the mounting hole 6 on the mounting plate 2. Then, the anti-detachment sleeve 41 is passed through the through hole on the generator set base and the mounting hole 6 on the mounting plate 2 from top to bottom. During insertion, the positioning block 71 and the sliding block 72 on the side wall of the anti-detachment sleeve 41 are aligned with the slot 8 on the inner wall of the mounting hole 6 and slide downwards along the slot 8. When the anti-detachment sleeve 41 is inserted into place, the lower surface of the abutment ring 42 contacts the upper surface of the generator set base, and at the same time, the positioning block 71 and the sliding block 72 have both entered the annular groove 9 through the lower end of the slot 8. At this time, the positioning block 71 and the sliding block 72 are both located in the annular groove 9, but due to the presence of the slot 8, if the anti-detachment sleeve 41 is pulled upwards at this time, the positioning block 71 and the sliding block 72 will move along the annular groove 9 to the slot 8 and disengage from the slot 8. Therefore, the anti-detachment sleeve 41 may still be pulled out.

[0038] Next, insert the bolt 51 into the inner cavity of the anti-detachment sleeve 41 from top to bottom, so that the head of the bolt 51 is located outside the upper end of the anti-detachment sleeve 41, and the shank of the bolt 51 protrudes from the lower end of the anti-detachment sleeve 41. Screw the locking block 52 onto the shank of the bolt 51 from below. Tighten the locking block 52, so that the locking block 52 moves upward and abuts against the lower end face of the extension seat 18. Continue to tighten the locking block 52, and the head of the bolt 51 will press down on the abutment ring 16, and the abutment ring 16 will drive the trigger rod 141 to slide downward. The lower end of the trigger rod 141 extends into the area where the two mounting grooves 10 are connected, and at the same time abuts against the ends of the two connecting seats 11, pushing the connecting seats 11 to slide within the mounting grooves 10 against the elastic force of the elastic element 12. The connecting seat 11 drives the sliding block 72 to slide circumferentially along the anti-detachment cylinder 41, causing the sliding block 72 to move from a position corresponding to the slot 8 to a position offset from the slot 8 (i.e., the sliding block 72 enters the depth of the annular groove 9 and is no longer aligned with any slot 8). At this time, even if the locking block 52 becomes loose, because both the sliding block 72 and the positioning block 71 are located in the annular groove 9 and the sliding block 72 is offset from the slot 8, the anti-detachment cylinder 41 cannot be pulled upwards, thus always connecting the generator set to the mounting plate 2. At the same time, the head of the bolt 51 presses the abutment ring 42 against the upper surface of the generator set base through the abutment ring 16 and the abutment ring 42, and the locking block 52 pulls the bolt 51 from below, together forming a clamping and fixing of the generator set.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
