Description

Technical Field

[0001] This utility model relates to the field of wind turbine testing equipment technology, and in particular to a wind turbine vibration testing platform that simulates the transportation process. Background Art

[0002] like Figure 3 The axial flow fans shown, after production, generally require vibration testing before shipment to assess the likelihood of internal structural loosening. Currently, the standard practice in factories is to use a small simulated transport vibration test bench for simulation testing. Specifically, plastic cable ties are threaded through the mounting holes on the fan and secured to the support frame on the simulated transport vibration test bench. However, this method of securing the fan with plastic cable ties has the following shortcomings in actual testing:

[0003] After each simulated vibration test of a fan is completed, the plastic cable ties need to be cut with scissors to disassemble the fan, which is inconvenient. Moreover, as production increases, the amount of plastic cable ties used to fix the test fans will also increase significantly, thus increasing the additional investment cost.

[0004] Therefore, there is an urgent need to improve the existing methods of fixing wind turbines during simulated vibration. Utility Model Content

[0005] The purpose of this invention is to provide a fan vibration testing platform that simulates the transportation process. By setting up a clamping assembly, the fan is clamped and fixed using two symmetrically distributed L-shaped locking hooks. This allows for quick and secure fixing of the fan, easy disassembly, and simple operation, effectively solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

A support frame is fixedly installed above the vibration table. The support frame includes at least one horizontally distributed assembly rod. Several clamping assemblies for fixing the fan are installed on the assembly rod.

Each L-shaped locking hook is composed of a vertically connected horizontal insert rod and a vertical locking rod. The surface of the vertical locking rod has threads, and a locking nut is connected to one end of the vertical locking rod near the locking plate. The locking nut is located below the locking plate. The horizontal insert rods of the two L-shaped locking hooks are located above the assembly rod and are distributed facing each other.

[0012] Furthermore, the support frame also includes two horizontally distributed fixed rods, which are respectively fixedly connected to the vibration table surface through the support rods. The fixed rods and the assembly rods are arranged vertically.

[0013] Furthermore, the assembly rod is located between the two fixed rods, and both ends of the assembly rod are slidably connected to the two fixed rods respectively. A locking component is provided between the assembly rod and the fixed rods.

[0026] The technical solution of this utility model will be clearly and completely described below through detailed embodiments and in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0027] Please refer to Figures 1-5This embodiment provides a fan vibration testing platform for simulating a transportation process, including a vibration device 1 and a vibration table 2 installed above the vibration device 1. A support frame 3 is fixedly installed above the vibration table 2. The support frame 3 includes at least one horizontally distributed assembly rod 31. The assembly rod 31 is equipped with several clamping components 4 for fixing the fan 6. The clamping components 4 include a horizontally distributed locking plate 41 and two symmetrically distributed L-shaped locking hooks 42. The L-shaped locking hooks 42 are composed of a vertically connected horizontal insertion rod 421 and a vertical locking rod 422. The surface of the vertical locking rod 422 has threads, and a locking nut 43 is connected to one end of the vertical locking rod 422 near the locking plate 41. The locking nut 43 is located below the locking plate 41. The horizontal insertion rods 421 of the two L-shaped locking hooks 42 are located above the assembly rod 31 and are distributed facing each other. The locking plate 41 is located below the assembly rod 31. The two ends of the locking plate 41 are respectively provided with U-shaped openings 411 for embedding the vertical locking rods 422. By adding several clamping components to the existing small simulated transport vibration test bench, the horizontal insertion rod is used to connect with the assembly hole on the fan. The fan is clamped and fixed by two symmetrically distributed L-shaped locking hooks and locking plates. The fan can be quickly and firmly fixed and is easy to disassemble. The operation process is relatively simple.

[0028] In some implementations, such as Figure 1 and Figure 2 As shown, the support frame 3 also includes two horizontally distributed fixed rods 32. The two fixed rods 32 are respectively fixedly connected to the vibration table surface 2 via support rods 33. The fixed rods 32 and the assembly rods 31 are arranged vertically. Specifically, the assembly rods 31 are located between the two fixed rods 32, and both ends of the assembly rods 31 are slidably connected to the two fixed rods 32. A locking assembly 5 is provided between the assembly rods 31 and the fixed rods 32. Specifically, both the assembly rods 31 and the fixed rods 32 are aluminum alloy grooves with a square cross-section. The four sides of the aluminum alloy grooves are respectively provided with sliding grooves 34 distributed along the length direction. The locking assembly 5 includes a fixing plate 51 and a locking bolt 52. One end of the fixing plate 51 is fixedly connected to the assembly rod 31, and the other end of the fixing plate 51 overlaps the upper surface of the fixed rod 32. The locking bolt 52 is threadedly connected to a locking block 53 that is slidably connected to the sliding groove 34. The end of the fixing plate 51 away from the assembly rod 31 is provided with a through hole 54 for the locking bolt 52 to pass through. In this way, the locking bolts can be loosened, thereby sliding and pushing the assembly rod to adjust its position, and then the locking bolts can be tightened to fix it.

[0029] As an example, such as Figure 1 As shown, there are two assembly rods 31.

[0030] As an improved implementation method, such as Figure 4 and Figure 5As shown, the upper surface of the locking plate 41 is provided with an anti-slip piece 44, which greatly increases the friction between the locking plate and the mounting rod, preventing the fan from shifting and improving the stability of the fan during testing. As an example, the anti-slip piece 44 is a rubber pad.

[0031] As an improved implementation method, such as Figure 4 and Figure 5 As shown, the locking plate 41 has upwardly protruding limiting plates 412 at both ends, and the anti-slip plate 44 is located between the two limiting plates 412. This allows the fan to be centrally fixed above the mounting rod, thus facilitating stable fan fixation.

[0032] In some specific implementation methods, such as Figure 5 As shown, the end of the horizontal insertion rod 421 is provided with an inlet head 4211, which allows for easy insertion into the mounting hole on the fan. Specifically, the inlet head 4211 is approximately conical in shape.

[0033] In some specific implementation methods, refer to Figures 3-5 To prevent the horizontal locking rod from damaging the fan due to overtightening of the locking nut, the vertical locking rod 422 is connected to a limiting nut 45, which is located above the locking plate 41. By adjusting the gap between the limiting nut and the locking plate, the limiting and safety function can be better utilized.

[0034] It should be noted that the vibration device 1 with the vibration table 2 is a conventional small simulated transportation vibration test bench, and existing simulated transportation vibration table products can be used. This application does not make any improvements to its vibration structure.

[0035] When testing, refer to Figures 3-5 Insert the horizontal insertion rods 421 of the two symmetrically distributed L-shaped locking hooks 42 into the mounting holes 61 on the fan 6. Then, insert the vertical locking rods 422 of the L-shaped locking hooks 42 into the U-shaped openings 411 on the locking plate 41 and tighten the locking nuts 43. This allows the fan 6 to be clamped and fixed by the cooperation of the two symmetrically distributed L-shaped locking hooks 42 and the locking plate 41. Refer to [reference needed] for further instructions. Figure 1 Multiple fans 6 to be tested are fixed on two mounting rods 31 respectively, thereby improving the efficiency of testing fans in a single test. After that, the equipment is started and the vibration test is started by operating on the control panel. After the test is completed, simply loosen the locking nut 43, and the L-shaped locking hook 42 can be easily removed by using the U-shaped opening 411 on the locking plate 41, so that each fan 6 can be quickly disassembled. The operation process is relatively simple.

[0036] The above embodiments are merely illustrative of the concept and technical solution of this utility model, and are not intended to limit this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.

[0037] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
