[0002] Skid-mounted landing gear is widely used in some helicopter designs due to its simple structure, light weight, and ease of maintenance. However, this type of landing gear usually requires external tools or equipment to move during transportation, and it also requires the use of jacks and tug wheels for disassembly and assembly during transport. This not only increases the complexity of operation but also limits the helicopter's ability to quickly dispatch and deploy.

[0003] Therefore, how to improve the ease of movement of helicopters using skid landing gear has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a helicopter transport vehicle to improve the ease of movement of helicopters using skid landing gear.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0007] The trailer includes two liftable cargo arms for supporting the landing gear of the helicopter. There are multiple landing gear fixing mechanisms, each of which is symmetrically arranged on the two cargo arms. The landing gear fixing mechanism is used to fix the diagonal struts of the landing gear. The trailer fixing mechanism is used to fix the trailer to restrict its movement.

[0008] Optionally, the helicopter transport vehicle described above also includes multiple trailer lifting stop devices, each of which is symmetrically distributed on the inner side of the two cargo arms.

Detailed Implementation

[0025] The core of this application is to provide a helicopter transport vehicle to improve the ease of movement of helicopters using skid landing gear.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] Skid-mounted landing gear is widely used in some helicopter designs due to its simple structure, light weight, and ease of maintenance. However, this type of landing gear usually requires external tools or equipment to move during transportation, and it also requires the use of jacks and tug wheels for disassembly and assembly during transport. This not only increases the complexity of operation but also limits the helicopter's ability to quickly dispatch and deploy.

[0028] Therefore, such as Figure 1 As shown in the figure, this application discloses a helicopter transport vehicle, including a movable trailer 10, a landing gear fixing mechanism 20, and a trailer fixing mechanism 30. The trailer 10 is fixed by the trailer fixing mechanism 30 to restrict its movement, thereby facilitating the loading of the helicopter onto the trailer. At the same time, the helicopter can be moved to a designated location along with the trailer 10, which improves the convenience of moving helicopters with skid-type landing gear 40, facilitates ground testing, and eliminates the need for complex removal and installation of the moving wheels during helicopter loading and transportation, saving time in loading and fixing the helicopter onto the trailer.

[0029] The following will combine Figures 1 to 3 The helicopter transport vehicles disclosed in the embodiments of this application will be explained and described in detail.

[0030] Among them, such as Figure 1 As shown, the trailer 10 may include two cargo arms 11, which are capable of lifting and lowering to detach the helicopter's landing gear 40, supported on the cargo arms 11, from the ground. This allows the trailer to move the helicopter to a designated location, improving its ground mobility and flexibility. It should be noted that, as... Figure 2 As shown, when the two cargo arms 11 of the trailer 10 are in the lowest position, the two cargo arms 11 can be inserted into the bottom inner side of the landing gear 40 of the helicopter, that is, between the two parallel skid tubes 42 of the landing gear 40. The two cargo arms 11 should be kept at a certain distance from the skid tubes 42 on the corresponding side to ensure that the landing gear fixing mechanism 20 fixes the diagonal brace 41 of the landing gear 40.

[0031] For example, the material of the trailer 10 can be carbon steel to ensure that the trailer 10 has high strength and load-bearing capacity. At the same time, the maximum load of the trailer 10 is not less than the maximum load of the helicopter, so that the trailer 10 can move the helicopter under various working conditions, improve the convenience of moving the helicopter with skid landing gear 40, and facilitate ground testing.

[0032] like Figure 1As shown, multiple landing gear fixing mechanisms 20 can be used, that is, two, four or more landing gear fixing mechanisms 20 can be used, and each landing gear fixing mechanism 20 is symmetrically arranged on the two cargo arms 11 to fix the diagonal brace 41 of the landing gear 40, thereby ensuring the reliability of the landing gear 40 connected to the trailer 10 and avoiding the risk of tilting during movement.

[0033] For example, such as Figure 1 As shown, two bow-shaped beams are connected between the two skid tubes 42 of the landing gear 40, that is, the landing gear 40 has four symmetrically arranged diagonal braces 41. At this time, the landing gear fixing mechanism 20 can use four, and is symmetrically located on the two cargo arms 11 respectively, so as to fix the four diagonal braces 41 of the landing gear 40 respectively, thereby ensuring the reliability of the connection between the trailer 10 and the landing gear 40 and avoiding the risk of tilting during movement.

[0034] Of course, when an arched beam is connected between the two skid tubes 42 of the landing gear 40, that is, the landing gear 40 has two symmetrically arranged diagonal braces 41, the landing gear fixing mechanism 20 can be two, and located on the two cargo arms 11 respectively, to fix the two diagonal braces 41 of the landing gear 40.

[0035] It should be noted that the number of landing gear fixing mechanisms 20 needs to be determined based on the specific structure of the landing gear 40, i.e., the number of diagonal braces 41 of the landing gear 40.

[0036] For example, such as Figure 1 As shown, the landing gear fixing mechanism 20 can be made of aluminum alloy, and the landing gear fixing mechanism 20 can include a lifting seat 21 and a lifting cover 22. The lifting seat 21 can be set on the cargo arm 11 of the trailer 10, and the lifting cover 22 and the lifting seat 21 are locked together by the locking device 23, so that the diagonal brace 41 of the landing gear 40 is clamped between the lifting seat 21 and the lifting cover 22, thereby realizing the connection and fixing between the trailer 10 and the landing gear 40.

[0037] For example, such as Figure 1 As shown, the landing gear fixing mechanism 20 may also include a fixing plate 24 and a shock absorber 25. The fixing plate 24 may be welded to the top surface of the cargo arm 11, and the lifting seat 21 may be fixed to the fixing plate 24 by the shock absorber 25, so as to reduce the shaking of the helicopter during transportation.

[0038] For example, such as Figure 1 As shown, the shock absorber 25 can adopt a columnar structure, and multiple shock absorbers 25 can be used, that is, there can be two, three, four or more shock absorbers 25. Each shock absorber 25 is symmetrically distributed on the fixed plate 24 to ensure the uniformity of force and improve the shock absorption effect during transportation.

[0039] For ease of understanding, the two ends of the shock absorber 25 are defined as the first end and the second end, respectively. The fixing plate 24 has a first threaded hole that connects to the first end of the shock absorber 25, and the first end of the shock absorber 25 has a threaded portion that mates with the first threaded hole, allowing the threaded portion of the first end of the shock absorber 25 to be threadedly connected to the first threaded hole on the fixing plate 24. Simultaneously, the second end of the shock absorber 25 has a second threaded hole, and the bottom surface of the support 21 has a threaded post that mates with the second threaded hole, allowing the threaded post on the support 21 to be threadedly connected to the second threaded hole at the second end of the shock absorber 25.

[0040] For example, such as Figure 1 and Figure 3 As shown, in order to facilitate the fixing of the diagonal brace 41 of the landing gear 40, each lifting seat 21 can be symmetrically tilted, and the inner side of the lifting seat 21 on the two cargo arms 11 is lower than the outer side of the lifting seat 21 on the two cargo arms 11, that is, the side of the lifting seat 21 on the two cargo arms 11 that is close to each other is lower than the side that is far away from each other, so as to match the diagonal brace 41 of the landing gear 40.

[0041] For example, such as Figure 1 and Figure 3 As shown, the lifting seat 21 can adopt an approximately right-angled triangular structure, and a first arc-shaped groove matching the diagonal brace 41 of the landing gear 40 is provided on the lifting seat 21. At the same time, a second arc-shaped groove matching the first arc-shaped groove is provided on the lifting cover 22. Thus, after the lifting cover 22 and the lifting seat 21 are locked together by the locking device 23, the diagonal brace 41 of the landing gear 40 can be clamped in the space enclosed by the first arc-shaped groove and the second arc-shaped groove, so as to avoid damage to the landing gear 40.

[0042] Of course, the lifting seat 21 can also adopt a rectangular structure, and the shock absorber 25 can adopt a columnar structure with different heights, so as to achieve the effect that the inner side of the lifting seat 21 on the two cargo arms 11 is lower than the outer side of the lifting seat 21 on the two cargo arms 11.

[0043] For example, the locking device 23 can be a quick-release self-locking hook, thereby achieving quick locking between the lifting cover 22 and the lifting seat 21. Of course, the locking device 23 can also be fixed by bolts or pins, which is not limited here. It should be noted that the quick-release self-locking hook is a conventional design, and will not be described in detail here.

[0044] In the above embodiments, the position of the landing gear fixing mechanism 20 on the cargo arm 11 needs to be determined according to the outward expansion distance of the diagonal brace 41 of the landing gear 40 when the actual helicopter is under different weights.

[0045] When the landing gear fixing mechanism 20 fixes the diagonal brace 41 of the landing gear 40, the cargo arm 11 of the trailer 10 is initially in its lowest position. At this time, there is a certain distance between the lifting seat 21 of the landing gear fixing mechanism 20 and the diagonal brace 41 of the landing gear 40, allowing the trailer 10 to smoothly enter the bottom of the landing gear 40. Figure 2 As shown; then, the cargo arm 11 of the trailer 10 is raised until the lifting seat 21 of the landing gear fixing mechanism 20 is close to the diagonal brace 41 of the landing gear 40, and at the same time the lifting cover 22 is installed, and the lifting cover 22 and the lifting seat 21 are quickly locked together by the locking device 23, as shown. Figure 3 As shown; finally, the cargo arm 11 of the trailer 10 is raised again, causing the landing gear 40 to leave the ground, so that the helicopter can be moved and loaded onto the trailer.

[0046] like Figure 1 As shown, in order to facilitate the loading of the helicopter onto the vehicle, the trailer 10 can be fixed by the trailer fixing mechanism 30 to restrict the movement of the trailer 10. This means that when the helicopter is loaded and transported, there is no need to perform complicated disassembly and assembly of the moving wheels. The trailer 10 can be fixed by the trailer fixing mechanism 30, which can save the time of fixing the helicopter on the vehicle.

[0047] For example, multiple trailer fixing mechanisms 30 can be used, i.e., there can be two, three, four or more trailer fixing mechanisms 30, and each trailer fixing mechanism 30 is symmetrically distributed on the inner side of the two cargo arms 11, i.e., on the opposite side of the two cargo arms 11, to prevent the trailer 10 from moving. Each trailer fixing mechanism 30 may include a base 31, a hook 32, and a pull ring 33. The base 31 may be made of carbon steel and can be welded to the inner side of the cargo arm 11. The hook 32 can be detachably mounted on the base 31 using bolts or other fasteners, while the pull ring 33 can be fixed to the transport vehicle using bolts or other fasteners, so that the hook 32 and the pull ring 33 can cooperate to achieve the effect of fixing the trailer 10 and preventing the trailer 10 from moving during transportation.

[0048] like Figures 1 to 3 As shown, the helicopter transport vehicle may also include multiple trailer lifting stop devices 50, that is, there may be two, three, four or more trailer lifting stop devices 50, and each trailer lifting stop device 50 is symmetrically distributed on the inner side of the two cargo arms 11 to prevent the cargo arms 11 from stopping and falling during lifting and transport. Figure 1 and Figure 3 As shown, when the trailer 10 is not moving or when the trailer 10 is fixed on the vehicle, the trailer lifting stop device 50 can be in a vertical position; as Figure 2 As shown, when the trailer lifting stop device 50 is not in use, it can be placed horizontally. It should be noted that the trailer lifting stop device 50 is a standard setting and will not be described in detail here.

[0049] For example, such as Figure 1 and Figure 3 As shown, the trailer lifting stop device 50 may include an adjusting screw 51, which can adjust the distance between the trailer lifting stop device 50 and the ground so that the trailer lifting stop device 50 can be in close contact with the ground, thereby adapting to uneven ground conditions.

[0050] The helicopter transport vehicle disclosed in this application uses a landing gear fixing mechanism 20 on the trailer 10 to fix the diagonal brace 41 of the landing gear 40. At this time, the cargo arm 11 of the trailer 10 can be raised to move the helicopter to the designated location. At the same time, the trailer 10 can be fixed by the trailer fixing mechanism 30 to restrict the movement of the trailer 10, thereby facilitating the loading of the helicopter.

[0051] The helicopter transport vehicle disclosed in this application uses a trailer fixing mechanism 30 to fix the trailer 10, thereby restricting the movement of the trailer 10. This facilitates the loading of the helicopter onto the vehicle and allows the helicopter to be moved together to a designated location via the trailer 10. This improves the ease of movement of helicopters using skid-type landing gear 40, facilitates ground testing, and eliminates the need for complex disassembly and assembly of the moving wheels during helicopter loading and transport, saving time on helicopter loading and fixing.
