Description

Technical Field

[0001] This utility model relates to the field of vibration damper testing technology, specifically a ship electric vibration damper testing device with a clamping and fixing structure. Background Technology

[0002] Marine electrical equipment (Marine power equipment) is a core component of a ship's electrical system, primarily responsible for power generation, distribution, conversion, energy storage, and power control. Power generation is typically accomplished by the engine or generator set. During engine or generator operation, the periodic combustion forces within the cylinders cause alternating torque on the crankshaft, inducing torsional vibration in the crankshaft system. Furthermore, the ship is subjected to wave impacts during operation, and the ship's electrical equipment casing also applies loads to the crankshaft system. Therefore, the crankshaft is subjected to complex vibration loads. When resonance occurs due to the superposition of these complex vibration loads, it can lead to a surge in stress on components such as the crankshaft, gears, and shafts, potentially causing breakage. Therefore, a crankshaft vibration damper is required between the crankshaft system and the ship's casing.

[0003] When testing marine electric vibration dampers, it is usually necessary to clamp and fix the vibration dampers. The size of the clamps used for vibration dampers varies depending on the size of the vibration damper. If different sizes of vibration dampers are tested, the crankshaft needs to be changed frequently, which makes the operation cumbersome and inefficient. Furthermore, the vibration damper needs to be changed and fixed frequently during testing, which is troublesome and inconvenient to use.

[0004] Based on this, a test device for marine electric vibration dampers with a clamping and fixing structure is provided, which can eliminate the drawbacks of existing devices. Utility Model Content

Furthermore, during vibration damper testing, the vibration damper needs to be changed and fixed frequently, which is troublesome and inconvenient to use.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-5 As shown, a test device for a marine electric shock absorber with a clamping and fixing structure includes a base 1 and a shock absorber body 22. A top plate 2 is provided above the base 1, and the top plate 2 is fixedly connected to the base 1 by several pillars 3. Several fixing rods 5 are provided on the base 1, and support plates 6 are slidably connected to the fixing rods 5. A pressure detection mechanism is provided below the support plate 6. Symmetrical first fixing plates 7 are provided on the support plate 6, and a first limiting mechanism is provided between the first fixing plates 7. A lifting mechanism is provided on the top plate 2, and a second limiting mechanism is provided at the bottom of the lifting mechanism. The shock absorber can be quickly limited by the first limiting mechanism and the second limiting mechanism, which is convenient for testing. It is applicable to shock absorbers of different specifications and has strong versatility. The pressure detection mechanism can obtain the pressure that the shock absorber body 22 can withstand by the numerical change.

[0026] In one embodiment, such as Figure 2 As shown, the pressure detection mechanism includes a pressure sensor 4, which is located on the base 1. The bottom surface of the support plate 6 is in contact with the pressure sensor 4. By squeezing the pressure sensor 4, the pressure that the damper body 22 can withstand can be obtained through the change in value.

[0027] In one embodiment, such as Figure 3 As shown, the first limiting mechanism includes a first electric push rod 8, which is located on one side of the first fixed plate 7. The output end of the first electric push rod 8 is provided with a first clamping plate 10, and the inner side of the first clamping plate 10 is provided with a first positioning head 12. Activating the first electric push rod 8 can drive the first fixed plate 7 to move relative to each other. The first positioning head 12 passes through the lifting ring 23 at the bottom of the shock absorber body 22 and squeezes against each other, thereby limiting the bottom of the shock absorber body 22.

[0028] In one embodiment, such as Figure 4 As shown, the base 1 is provided with a first sliding groove 9, and the bottom of the first clamping plate 10 is provided with a first slider 11, and the first slider 11 is slidably connected within the first sliding groove 9, which facilitates the position adjustment of the first clamping plate 10.

[0029] In one embodiment, such as Figure 1 As shown, the lifting mechanism includes a pressure plate 14, which is slidably connected to the support column 3. A hydraulic cylinder 13 is provided on the top plate 2, and the output end of the hydraulic cylinder 13 is fixedly connected to the pressure plate 14. Starting the hydraulic cylinder 13 can drive the pressure plate 14 to press down.

[0030] In one embodiment, such as Figure 2 As shown, the second limiting mechanism includes a mounting plate 15, which is located at the bottom of the pressure plate 14. A symmetrical second fixing plate 16 is provided at the bottom of the mounting plate 15. A second electric push rod 17 is provided on the second fixing plate 16. A second clamping plate 19 is provided at the output end of the second electric push rod 17. A second positioning head 21 is provided on the inner side of the second clamping plate 19. Activating the second electric push rod 17 can drive the second clamping plate 19 to move relative to each other. The second positioning head 21 passes through the lifting ring 23 at the top of the shock absorber body 22 and squeezes against each other, thereby limiting the top of the shock absorber body 22.

[0031] In one embodiment, such as Figure 5 As shown, the bottom surface of the mounting plate 15 is provided with a second sliding groove 18, and the top of the second clamping plate 19 is provided with a second slider 20. The second slider 20 is slidably connected within the second sliding groove 18, which facilitates the position adjustment of the second clamping plate 19.

[0032] In one embodiment, such as Figure 1 As shown, the shock absorber body 22 is equipped with lifting rings 23 at both the top and bottom.

[0033] Working principle: When in use, the shock absorber body 22 is placed in a suitable position. Activating the first electric push rod 8 can drive the first fixed plate 7 to move relative to each other. The first positioning head 12 passes through the lifting ring 23 at the bottom of the shock absorber body 22 and presses against each other, thereby limiting the bottom of the shock absorber body 22. Activating the second electric push rod 17 can drive the second clamping plate 19 to move relative to each other. The second positioning head 21 passes through the lifting ring 23 at the top of the shock absorber body 22 and presses against each other, thereby limiting the top of the shock absorber body 22. Activating the hydraulic cylinder 13 can drive the pressure plate 14 to press down, which can completely compress the shock absorber body 22. The pressure sensor 4 can be squeezed through the support plate 6. The pressure of the shock absorber body 22 can be obtained by the change in value, thereby testing the pressure value of the shock absorber body 22. After this is completed, the hydraulic cylinder 13 drives the pressure plate 14 to reset.
