[0038] The following is a detailed description of this experimental novelty with reference to the accompanying drawings:

[0039] Figure 1-3 The utility model shows a helicopter tail boom auxiliary installation tool, comprising:

[0040] Tail beam front mounting bracket 1;

[0041] A front height adjuster 2, which is fixed to the top of the tail beam front mounting frame 1 through a first set of limit blocks 3;

[0042] A front tail beam frame bracket 4, the bottom of which is in contact with the front height adjuster 2, and both ends of the front tail beam frame bracket 4 are detachably connected to the tail beam front mounting frame 1;

[0043] Tail beam rear mounting frame 7;

[0044] A rear height adjuster 8, which is fixed to the top end of the tail beam rear mounting frame 7 by a second set of limit blocks 9;

[0045] The rear tail beam frame bracket 10 has its bottom in contact with the rear height adjuster 8 , and both ends of the rear tail beam frame bracket 7 are detachably connected to the tail beam rear mounting frame 10 .

[0046] Working principle:

[0047] When the utility model is used, the two ends of the front tail beam frame bracket 4 are first fixed to the front tail beam mounting frame 1, and the two ends of the rear tail beam frame bracket 10 are fixed to the rear tail beam mounting frame 7, and then the front end of the helicopter tail beam with a large radius is directly placed on the front tail beam frame bracket 4, and the rear end of the helicopter tail beam with a small radius is directly placed on the rear tail beam frame bracket 10;

[0048] The front tail beam frame bracket 4 is connected to the front height adjuster 2 by bolts, and the rear tail beam frame bracket 10 is connected to the rear height adjuster 8 by bolts to achieve rising and falling, thereby completing the adjustment of the level and height of the helicopter tail beam;

[0049] The utility model can reduce potential safety hazards during the installation process through a simple structure. At the same time, the total height of the auxiliary installation tooling is about 1.6m, and the volume is light and easy to carry, so it is convenient to be used in multiple different locations to complete the tail beam assembly operation.

[0050] As in the above scheme, the tail beam front mounting frame 1 has universal wheels at its bottom four corners; the tail beam rear mounting frame 7 has universal wheels at its bottom four corners;

[0051] The tail beam front mounting frame 1 and the tail beam rear mounting frame 7 are both formed by welding 60*60 square steel.

[0052] Working principle:

[0053] By using a mounting frame made of 60*60 square steel welded together, the structure is simpler, and a universal wheel is added for easy use to complete the transfer and installation of the tail beam;

[0054] The universal wheels are selected because, firstly, they have a strong carrying capacity, secondly, they have good flexibility, making the operation of the equipment easier and more flexible; thirdly, they have strong wear resistance, allowing the utility model to cope with various different ground surfaces.

[0055] As in the above solution, a threaded screw is provided between the front height adjuster 2 and the rear height adjuster 8, and the threaded screw structure includes:

[0056] A guide tube 21, the interior of which is provided with threads, and the guide tube 21 is fixed to the first set of limit blocks 3;

[0057] A threaded rod 22, the surface of which is provided with threads, the threaded rod 22 is threadedly connected to the guide tube 21, and the top of the threaded rod 22 is in contact and connected with the bottom ends of the front tail beam frame bracket 4 and the rear tail beam frame bracket 10;

[0058] A rotating handle 23 is fixed on the threaded rod 22 .

[0059] Working principle:

[0060] The specific operation of the structure for adjusting the vertical height of the front tail beam frame bracket 4 and the rear tail beam frame bracket 10 by means of a threaded screw is as follows:

[0061] In this working process, the front height adjuster 2 is taken as an example, the guide tube 21 is fixed in the middle of the first group of limit blocks 3, and the threaded rod 22 is moved upward by rotating the rotating handle 23. When we rotate, due to the relative position relationship between the screw rod 22 and the guide tube 21, the screw rod 22 will move along the thread in the guide tube 21, thereby moving upward or downward, and the height adjustment operation of the helicopter tail beam is completed through the contact connection between the top end of the threaded rod 22 and the bottom end of the front tail beam frame bracket 4;

[0062] The advantage of this transmission is that it can achieve high-precision and high-efficiency linear motion; since the spiral portion of the thread 22 is continuous, it can provide continuous linear motion without problems such as motion interruption or jump;

[0063] The threaded screw has a simple structure and can more intuitively and easily adjust the height of the helicopter tail boom, reducing the trouble and maintenance costs of frequent replacement, and reducing the cost of use to a certain extent.

[0064] As in the above solution, the front tail beam frame bracket 4 structure includes:

[0065] The front bracket 41 is a semi-arc structure;

[0066] A first set of support rods 5, which are fixedly connected to both ends of the front bracket 41;

[0067] The first set of fixing tubes 6 are symmetrically arranged on both sides of the top of the tail beam front mounting frame 1 , and the first set of supporting rods 4 are sleeved inside the first set of fixing tubes 6 .

[0068] Working principle:

[0069] In the present invention, the two ends of the front tail beam frame bracket 4 are detachably connected to the front tail beam mounting frame 1 by welding a first set of support rods 5 at both ends of the front bracket 41 and directly sleeved in a first set of fixed tubes 6;

[0070] The main function of the first set of support rods 5 is to prevent the front tail beam frame bracket 4 from rotating during adjustment;

[0071] As in the above solution, the rear tail beam frame bracket structure 10 includes:

[0072] The rear bracket 101 is a semi-arc structure;

[0073] A second set of support rods 11, which are fixedly connected to both ends of the rear bracket 101;

[0074] The second set of fixing tubes 12 are symmetrically arranged on both sides of the top of the tail beam rear mounting frame 7 , and the second set of supporting rods 11 are sleeved inside the second set of fixing tubes 12 .

[0075] Working principle:

[0076] In the present invention, the two ends of the rear tail beam frame bracket 7 are detachably connected to the rear tail beam mounting frame 10 by welding a second set of support rods 12 at both ends of the rear bracket 101 and directly sleeved in the second set of fixed tubes 11;

[0077] The main function of the second group of support rods 12 is to prevent the rear tail beam frame bracket 10 from rotating during adjustment.

[0078] As in the above solution, the bottom ends of the front bracket 41 and the rear bracket 101 are both provided with limiting grooves.

[0079] Working principle:

[0080] In this working process, the front height adjuster 2 is taken as an example, and the bottom of the front tail beam frame bracket 4 is in contact with the front height adjuster in such a way that the top end of the threaded rod 22 of the height adjuster 2 is inserted into the limiting groove 411;

[0081] When the threaded rod 22 supports the front bracket 41 to adjust upward or downward, the limiting groove 411 ensures that the front bracket 41 will not fall off during the height adjustment process.

[0082] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
