Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] Please refer to Figures 1 to 14 As shown:

[0044] Embodiment 1: The present invention provides a marine gearbox vibration test device, comprising a platform assembly 2, the platform assembly 2 comprising a vertical vibration table 201 and a horizontal vibration table 202, the horizontal vibration table 202 is laterally plugged into the top of the vertical vibration table 201, and the vertical vibration table 201 is plugged into the top of the mounting seat 1 through track rods on both sides; a locking assembly 3, the locking assembly 3 comprising a locking block 301 and an electromagnet a302, the locking block 301 is plugged into the side of the mounting seat 1, and the electromagnet a302 is fixedly installed on the side of the mounting seat 1, and the electromagnet a302 will adsorb the locking block 301 after power is turned on; a control assembly, the control assembly is composed of a driving mechanism 4 and a generating mechanism 5;

[0045] The driving mechanism 4 includes a driving motor 401, a driving disk 402, a linkage rod 403, a driving block 404, a positioning rod 405 and a reduction gear 406. The driving motor 401 is fixedly mounted on the side of the mounting seat 1, and the driving disk 402 is rotatably connected to the inside of the mounting seat 1. The rotating shaft of the driving motor 401 is transmission-connected to the driving disk 402, and the linkage rod 403 is plugged into the top of the mounting seat 1. The driving block 404 is radially plugged into the inside of the driving disk 402, and the positioning rod 405 is rotatably connected to the inside of the driving disk 402, and the reduction gear 406 is rotatably connected to the inside of the mounting seat 1.

[0046] The generating mechanism 5 includes a lifting seat 501, a control rod 502, a switching block 503 and an electromagnet b504. The lifting seat 501 is inserted into the interior of the mounting seat 1, the control rod 502 is inserted into the interior of the lifting seat 501, and the top of the control rod 502 is rotatably connected to the interior of the vertical vibration table 201, the switching block 503 is inserted into the interior of the lifting seat 501, and the electromagnet b504 is fixedly installed in the interior of the lifting seat 501. The electromagnet b504 will adsorb the switching block 503 after power is turned on.

[0047] The control component has two usage modes, namely vertical vibration mode and horizontal vibration mode. The two usage modes can be switched by controlling the power on and off of electromagnet a302 and electromagnet b504.

[0048] In the embodiment of the present disclosure, a control tension spring 5031 is provided at the top of the switching block 503, and the two ends of the control tension spring 5031 are respectively fixedly connected to the top of the switching block 503 and the inside of the lifting seat 501, so that the switching block 503 cannot rotate inside the lifting seat 501, and a control tooth block 5032 is provided on the outside of the switching block 503, and a control tooth groove 5021 is provided at the bottom of the control rod 502. When the electromagnet b504 is not energized, the control tooth block 5032 is plugged into the inside of the control tooth groove 5021 under the action of the control tension spring 5031. In use, when the electromagnet a302 and the electromagnet b504 are not energized, the control component is in a vertical vibration mode, and at this time, the driving mechanism 4 can drive the vertical vibration table 201 through the generating mechanism 5. and the horizontal vibration table 202 on its top generates vibration action in the up and down directions. When the electromagnet a302 and the electromagnet b504 are not energized, under the action of the control tension spring 5031, the control tooth block 5032 is plugged into the inside of the control tooth groove 5021, so that the control rod 502 can no longer rotate on the top of the lifting seat 501. The top of the lifting seat 501 is provided with a spiral functional groove 5011, and the inside of the control rod 502 is provided with a functional protrusion 5022, which is plugged into the inside of the functional groove 5011. Since the functional protrusion 5022 is plugged into the inside of the functional groove 5011, the control rod 502 can no longer change its position in the vertical direction outside the lifting seat 501. That is, at this time, the lifting seat 501 and The control rod 502 forms a stable whole, and the movement state of the two is always the same. A driving column 4041 is provided on the side of the driving block 404, and a driving groove 4031 is provided at the bottom of the linkage rod 403. The driving column 4041 is inserted into the driving groove 4031. Therefore, at this time (the control component is in the vertical vibration mode), when the driving motor 401 rotates, the driving motor 401 can drive the driving disk 402 to rotate. When the driving disk 402 rotates, the driving block 404 can rotate synchronously with the driving disk 402. When the driving block 404 rotates, the driving column 4041 can drive the linkage rod 403 to move up and down through the driving groove 4031. The sides of the linkage rod 403 and the lifting seat 501 are both provided with linkage racks 4032. The linkage rack 4032 of 403 is connected to the large gear of the reduction gear 406, and the linkage rack 4032 of the lifting seat 501 is connected to the small gear of the reduction gear 406. When the linkage rod 403 moves, the lifting seat 501 can also move up and down under the cooperation of the linkage rack 4032 and the reduction gear 406. Since the lifting seat 501 and the control rod 502 are in a stable whole at this time, when the lifting seat 501 moves, the vertical vibration table 201 can be driven to move up and down synchronously through the control rod 502 to generate vibration action, so as to perform vertical vibration detection on the marine gear box installed on the horizontal vibration table 202. The operation is convenient and flexible. When the control component is in the vertical vibration mode, the control rod 502 cannot rotate by itself.Therefore, under the cooperation of the swing gear 5023 and the swing rack 2021, the horizontal vibration table 202 can no longer move horizontally on the vertical vibration table 201, so that the vertical vibration table 201 can drive the horizontal vibration table 202 to move synchronously when moving up and down to achieve the test operation, which is stable to use. Under the action of the separation tension spring 3012, there will be no interference between the locking hook 3011 and the locking groove 2011, and the device will not be stuck, which has extremely strong stability.

[0049] In the embodiment of the present disclosure, a swing gear 5023 is provided on the top of the control rod 502, and a swing rack 2021 is provided inside the horizontal vibration table 202. The gear teeth of the swing gear 5023 and the swing rack 2021 are engaged for transmission. In use, when the electromagnet a302 and the electromagnet b504 are in the energized state, the control component is in the horizontal vibration mode. After being energized, the electromagnet b504 will adsorb the switching block 503. After the switching block 503 is adsorbed and moved, the control tension spring 5031 will be stretched, and the control tooth block 5032 will fall out of the control tooth groove 5021, thereby releasing the overall relationship between the lifting seat 501 and the control rod 502. When the overall relationship between the lifting seat 501 and the control rod 502 is released, the supporting and positioning function of the functional protrusion 5022 on the control rod 502 through the functional groove 5011 will be synchronously invalidated. , thereafter, under the deadweight of the platform assembly 2 and the gear box, the vertical vibration table 201 will move downward to the lowest position, and thereafter the platform assembly 2 can generate horizontal vibration. At this time, since the overall relationship between the lifting seat 501 and the control rod 502 is released, the lifting seat 501 will still reciprocate up and down under the drive of the driving mechanism 4. When the lifting seat 501 reciprocates up and down, the functional groove 5011 can drive the control rod 502 to reciprocate through the functional protrusion 5022. When the control rod 502 reciprocates, the swing gear 5023 can drive the horizontal vibration table 202 to reciprocate horizontally on the top of the vertical vibration table 201 through the swing rack 2021, thereby realizing horizontal vibration action, fast switching, flexible use, and can realize the horizontal vibration test of the gear box, with strong adaptability.

[0050] In the embodiment of the present disclosure, a locking groove 2011 is provided on the outside of the track rod of the vertical vibration table 201, and a locking hook 3011 is provided on the top of the locking block 301, and a separation tension spring 3012 is provided inside the locking block 301, and the two ends of the separation tension spring 3012 are respectively fixedly connected to the inside of the locking block 301 and the inside of the mounting seat 1. Under the action of the separation tension spring 3012, when the electromagnet a302 is not energized, the locking hook 3011 will not be inserted into the locking groove 2011. In use, when the electromagnet a302 is not energized, the locking hook 3011 will not be inserted into the locking groove 2011. When 302 is energized, it will absorb the locking block 301 and move it. When the locking block 301 moves, it will pull the separation spring 3012, and during the movement, the locking hook 3011 can be inserted into the locking groove 2011, thereby locking the vertical vibration table 201, making it impossible for the vertical vibration table 201 to move in the vertical direction. Therefore, the vertical vibration table 201 can provide stable support for the rotation of the position control rod 502, so as to realize the vibration of the horizontal vibration table 202 in the horizontal direction, and the stability is extremely strong.

[0051] In the disclosed embodiment, the rod body of the positioning rod 405 is provided with a thread on the outside, and the positioning rod 405 is screwed to the inside of the driving block 404 through the rod body thread. In use, the vibration amplitude of the platform assembly 2 can be adjusted by the driving mechanism 4, and can adapt to different vibration test requirements of the marine gearbox. However, when the vibration amplitude of the platform assembly 2 needs to be adjusted, it is only necessary to rotate the positioning rod 405. When rotating, the positioning rod 405 can drive the driving block 404 to move radially along the driving disk 402 through the rod body thread, thereby changing the radius of the driving block 404 when following the rotation of the driving disk 402, that is, changing the maximum up and down movement distance of the linkage rod 403 and the lifting seat 501. Since the horizontal and vertical vibrations of the platform assembly 2 are realized by the up and down reciprocating movement of the lifting seat 501, the change in the maximum up and down movement distance of the lifting seat 501 changes the vibration amplitude of the platform assembly 2, which is convenient for adjustment.

[0052] Specific usage and function of this embodiment: In the present invention, after the marine gearbox is fixed on the top of the horizontal vibration table 202, the vibration test operation can be started. First, the amplitude of the platform component 2 is adjusted according to the test requirements. The vibration amplitude of the platform component 2 can be adjusted by the driving mechanism 4, which can adapt to the different vibration test requirements of the marine gearbox. However, when the vibration amplitude of the platform component 2 needs to be adjusted, it is only necessary to rotate the positioning rod 405. When the positioning rod 405 rotates, it can drive the driving block 404 to move along the radial direction of the driving disk 402 through the rod body thread, thereby changing the radius of the driving block 404 when following the driving disk 402 to rotate, that is, changing the maximum up and down moving distance of the linkage rod 403 and the lifting seat 501. The horizontal and vertical vibrations of the platform assembly 2 are both realized by the up and down reciprocating movement of the lifting seat 501. Therefore, the change in the maximum up and down movement distance of the lifting seat 501 changes the vibration amplitude of the platform assembly 2. After the adjustment is completed, the control assembly is switched to a suitable test mode for testing. When the electromagnet a302 and the electromagnet b504 are not energized, the control assembly is in a vertical vibration mode. At this time, the driving mechanism 4 can drive the vertical vibration table 201 and the horizontal vibration table 202 on its top to generate up and down vibration movements through the generating mechanism 5. When the electromagnet a302 and the electromagnet b504 are not energized, under the action of the control tension spring 5031, the control tooth block 5032 is inserted into the inside of the control tooth groove 5021, from At this time, the control rod 502 can no longer rotate on the top of the lifting seat 501, and because the functional protrusion 5022 is inserted into the inside of the functional groove 5011, the control rod 502 can no longer change its position in the vertical direction outside the lifting seat 501, that is, at this time, the lifting seat 501 and the control rod 502 form a stable whole, and the movement state of the two is always the same, so that at this time (the control component is in the vertical vibration mode), when the driving motor 401 rotates, the driving motor 401 can drive the driving disk 402 to rotate, and when the driving disk 402 rotates, the driving block 404 can rotate synchronously with the driving disk 402, and when the driving block 404 rotates, the driving column 4041 can drive the linkage rod 403 upward through the driving groove 4031. When the linkage rod 403 moves, the lifting seat 501 can also move up and down under the cooperation of the linkage rack 4032 and the reduction gear 406. Since the lifting seat 501 and the control rod 502 are in a stable whole at this time, when the lifting seat 501 moves, the control rod 502 can drive the vertical vibration table 201 to move up and down synchronously to generate vibration, so as to perform vertical vibration detection on the marine gearbox installed on the horizontal vibration table 202. When the control component is in the vertical vibration mode, the control rod 502 cannot rotate by itself, so under the cooperation of the swing gear 5023 and the swing rack 2021, the horizontal vibration table 202 can no longer be displaced in the horizontal direction on the vertical vibration table 201.Therefore, the vertical vibration table 201 can drive the horizontal vibration table 202 to move synchronously when moving up and down to realize the test operation, and the use is stable. Under the action of the separation tension spring 3012, there will be no interference between the locking hook 3011 and the locking groove 2011, and the device will not be stuck. When the electromagnet a302 and the electromagnet b504 are in the power-on state, the control component is in the horizontal vibration mode. The electromagnet b504 will absorb the switching block 503 after being energized. After the switching block 503 is absorbed and moved, the control tension spring 5031 will be lengthened, and The control tooth block 5032 will be out of the control tooth groove 5021, thereby releasing the overall relationship between the lifting seat 501 and the control rod 502. When the overall relationship between the lifting seat 501 and the control rod 502 is released, the supporting and positioning function of the functional protrusion 5022 on the control rod 502 through the functional groove 5011 will be simultaneously invalidated. Thereafter, under the dead weight of the platform assembly 2 and the gear box, the vertical vibration table 201 will move downward to the lowest position. Thereafter, the platform assembly 2 can generate horizontal vibration. At this time, due to the lifting seat 501 and the control rod 50 2 is released, but the lifting seat 501 will still reciprocate up and down under the drive of the driving mechanism 4. When the lifting seat 501 reciprocates up and down, the functional groove 5011 can drive the control rod 502 to reciprocate through the functional protrusion 5022. When the control rod 502 reciprocates, the swing gear 5023 can drive the horizontal vibration table 202 to reciprocate horizontally on the top of the vertical vibration table 201 through the swing rack 2021, thereby realizing the vibration action in the horizontal direction, fast switching, flexible use, and can realize the gear box In the horizontal vibration test, when the electromagnet a302 is energized, it will absorb the locking block 301 and move it. When the locking block 301 moves, it will pull the tension spring 3012, and during the movement, the locking hook 3011 can be inserted into the locking groove 2011, thereby locking the vertical vibration table 201, so that the vertical vibration table 201 cannot move in the vertical direction, so that the vertical vibration table 201 can provide stable support for the rotation of the position control rod 502, so as to realize the vibration of the horizontal vibration table 202 in the horizontal direction.

[0053] In another embodiment, electromagnet a302 and electromagnet b504 are connected in the same control circuit, which facilitates the synchronous control of the power on and off of electromagnet a302 and electromagnet b504, facilitates the rapid switching of the control component between the two usage modes, and further improves the flexibility of the device.
