Abstract
Description
Technical Field
[0001] This utility model relates to the field of helicopter rotor cleaning, and in particular to a mobile helicopter rotor cleaning vehicle. Background Technology
[0002] Existing helicopter rotor cleaning methods have many drawbacks. During rotor cleaning, there is a lack of tools specifically designed for particular models (such as Bell helicopters), and often only rudimentary support devices can be temporarily erected. This makes it difficult to ensure the stability of the rotor placement, increasing the risk of scratches and wear. There is no protective structure to effectively prevent damage to the blades. Moreover, conventional cleaning sites do not have a well-planned drying area and are usually placed haphazardly, which cannot ensure the safety of the rotor during the drying process and is prone to secondary damage due to shaking. In addition, traditional cleaning methods lack convenient mobility, and the transportation of cleaning equipment and tools is extremely inconvenient, requiring a lot of manpower and time. There are also no reliable measures for fixing the rotor hub, which often leads to the rotor hub sliding during the cleaning operation, affecting the accuracy and efficiency of the cleaning.
[0003] Therefore, it is necessary to provide a mobile helicopter rotor cleaning vehicle to solve the above-mentioned technical problems. Utility Model Content

[0029] The mounting bracket 1 has eight casters 9 on each side of its bottom.
[0030] The inner side of the groove in the placement slot is covered with a protective structure, which can be protected with a sponge pad or silicone sleeve to prevent the blades from being scratched and worn.
[0031] The width of the two first placement slots 23 on the surface of the first support block 21 is smaller than the width of the other two second placement slots 24. The width of the four slots 82 on the surface of the third support block 81 is the same. The width of the two third placement slots 33 on the surface of the second support block 31 is larger than the width of the other two fourth placement slots 34.

The second placement slot 23, the fifth placement slot 83 and the fourth placement slot 34 are kept on the same horizontal line and are used to place a rotor. The rotor and the rotor end of the first placement slot 23 are opposite to each other, so that all four rotors can be placed on one cleaning vehicle without the rotors being squeezed and stuck together.
[0032] Of the eight movable wheels, the two on the far right are directional wheels, which can be braked to limit movement, while the other six are omnidirectional wheels, which can enable free movement within a plane.
[0033] The cleaning tank 22, the opening slot 82 and the support slot 32 are on the same horizontal line, which facilitates the installation and cleaning of the rotor.
[0034] The working principle of the mobile helicopter rotor cleaning vehicle provided by this utility model is as follows:
[0035] During operation, the rotor is first placed on the surface of the cleaning tank 22, the resting tank 32 and the opening slot 82 of the first support frame 2, the second support frame 3 and the third support frame 8 for cleaning.
[0036] After cleaning, the two rotor blades are rotated 90 degrees and inserted into the first placement slot 23. The two rotor blades are respectively inserted into the two first placement slots 23. The middle part of the rotor blades is inserted into the fifth placement slot 83, and the other side of the rotor blades is inserted into the third placement slot 33.
[0037] The other two rotor blades are reversed, with the tails of the first two rotor blades ending opposite, and are inserted into the second placement slot 24, the fifth placement slot 83, and the fourth placement slot 24, respectively.
[0038] Compared with related technologies, the mobile helicopter rotor cleaning vehicle provided by this utility model has the following advantages:
[0039] This utility model provides a mobile helicopter rotor cleaning cart. Through the cooperation of a mounting frame 1, a first support frame 2, a second support frame 3, a third support frame 8, and casters 9, when the rotor is removed for cleaning, it can be placed on the cleaning groove 22 surface of the first support frame 2, the second support frame 3, and the third support frame 8 for fixed cleaning. The first support frame 2, the second support frame 3, and the third support frame 8 are provided with one horizontal groove and four vertical grooves.

The internal gap of the vertical groove at each support point is different, and the gap value varies with the thickness of the rotor blade, ensuring that the rotor blade does not shake on the cleaning cart during drying and that the rotor blade is safe and undamaged. Casters are provided at the bottom, allowing free movement within a plane, improving the practicality and functionality of the device.
[0040] Second Embodiment
[0041] Please refer to the following: Figure 3 and Figure 4 Based on the mobile helicopter rotor cleaning vehicle provided in the first embodiment of this application, the second embodiment of this application proposes another mobile helicopter rotor cleaning vehicle. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.
[0042] Specifically, the second embodiment of this application provides a mobile helicopter rotor cleaning vehicle in that the mobile helicopter rotor cleaning vehicle has four limit grooves 10 on the top of the third support block 81, and a limit rod 11 is fixedly installed inside the limit groove 10. A spring 12 is sleeved on one side of the outer surface of the limit rod 11, and a squeezing block 13 is sleeved on the other side of the outer surface of the limit rod 11.
[0043] A connecting block 14 is fixedly installed on one side of the extrusion block 13, and a clamping plate 15 is fixedly connected to one side of the connecting block 14.
[0044] Springs 12 can be installed on the top of all support blocks to push the clamping plates 15 to change the spacing of the placement slots, thereby adapting to rotors of various thicknesses.
[0045] The working principle of the mobile helicopter rotor cleaning vehicle provided by this utility model is as follows:
[0046] During operation, the restoring force of the spring 12 first pushes the pressing block 13 to move away from the spring 12. The pressing block 13 drives the connecting block 14 and the clamping plate 15 to move, and the clamping plate 15 fits against the surface of the fifth placement groove 83.
[0047] Before placing the rotor, push the clamp 15 toward the side closer to the spring 12 to facilitate the placement of the rotor into the fifth placement slot 83. Then release the spring 12. The restoring force of the spring 12 pushes the clamp 15 to adhere to the rotor surface, confining the rotor inside the fifth placement slot 83.
[0048] Compared with related technologies, the mobile helicopter rotor cleaning vehicle provided by this utility model has the following advantages:
[0049] This utility model provides a mobile helicopter rotor cleaning vehicle. The spring 12 pushes the clamp 15 to move, so that the clamp 15 moves inside the fifth placement slot 83. The spacing of the fifth placement slot 83 can be adjusted according to the width of the rotor, which can be adapted to clean and dry different types of rotors, thus improving the practicality and flexibility of the device.
[0050] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
