[0044] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Instead, these embodiments are provided to make the present invention more thorough and complete and to fully convey the scope of the present invention to those skilled in the art.

[0045] like Figure 1-5 As shown, a ground launch platform includes:

[0046] Support module 2, which includes a spliced ​​frame structure, and a lifting mechanism 4 is provided at the top of the support module 2;

[0047] The first half sleeve 5 and the second half sleeve 6 are arranged at the top of the support module 2 and below the lifting mechanism 4. The second half sleeve 6 and the first half sleeve 5 are detachably connected to form a first cylindrical structure.

[0048] The rotating module 3 is used to install the missile, and the lifting mechanism 4 is used to lift and lower the rotating module 3. The rotating module 3 is provided with a rotating shaft 7 that cooperates with the first cylindrical structure;

[0049] The limiting mechanism 1 is arranged at the top of the supporting module 2 and is used to control the inclination angle of the rotating module 3.

[0050] Specifically, the support module 2 is trapezoidal in shape, which is convenient for dispersed transportation and can be manually carried to dangerous areas. It also provides stable support after assembly. The rotating module 3 is lifted into place by the lifting mechanism 4 to realize the lifting and transportation of ammunition. The first half-axle sleeve 5 and the second half-axle sleeve 6 are installed in conjunction with the rotating shaft 7, thereby facilitating the rotation of the rotating module 3 to adjust the angle.

[0051] The first half-axle sleeve 5 and the second half-axle sleeve 6 are detachably connected to each other, and the rotating shaft 7 can be snap-fitted with the first half-axle sleeve 5 without axial movement. Then, the second half-axle sleeve 6 and the first half-axle sleeve 5 form a first cylindrical structure to connect the rotating shaft 7, so that the rotating shaft 7 can rotate in the first cylindrical structure.

[0052] Further, the lifting mechanism 4 can be integrated on the support module 2 or assembled to the support module 2 in separate components in sequence. A centering roller bearing cooperating with the first cylindrical structure can be provided on the rotating shaft 7, which can compensate for the eccentric tolerance and reduce the rotational resistance.

[0053] In this embodiment, the lifting mechanism 4 includes two roller groups 4.1. The two roller groups 4.1 are symmetrically arranged at the top of the support module 2 through L-shaped brackets, and the two roller groups 4.1 lift the rotating module 3 through a towing rope.

[0054] Specifically, a winch 4.2 is provided on the side wall of the support module 2. The winch 4.2 and the roller group 4.1 form a winch structure through a towing rope. During use, the rotating module 3 is avoided by the swinging of the towing rope, and the rotating module 3 is wound from one side of the first half shaft sleeve 5 to above the first half shaft sleeve 5, so that the rotating shaft 7 is connected to the first half shaft sleeve 5.

[0055] In this embodiment, an elastic frame assembly is detachably connected to the rotating module 3.

[0056] Specifically, a missile is connected through the elastic frame assembly, and the elastic frame assembly is provided with various different model specifications.

[0057] In this embodiment, the rotating module 3 includes an H-shaped frame, and the limiting mechanism 1 includes:

[0058] An arc-shaped groove 1.1, which is arranged with the first half shaft sleeve 5 as the center of the circle; <0000,128>A third half shaft sleeve 8 and a fourth half shaft sleeve 9. The third half shaft sleeve 8 is slidably connected in the arc-shaped groove 1.1 through a slider. The fourth half shaft sleeve 9 is detachably connected to the third half shaft sleeve 8 to form a second cylindrical structure. The two ends of the H-shaped frame are respectively connected to the first cylindrical structure and the second cylindrical structure. <00001,30>Specifically, the inclination angle of the rotating module 3 is adjusted by the sliding of the second cylindrical structure in the arc-shaped groove 1.1.

[0061] In this embodiment, the frame structure includes:

[0062] A first rectangular frame 2.1 and two U-shaped frames 2.2. The two U-shaped frames 2.2 are symmetrically arranged at both ends of the first rectangular frame 2.1 to form a structure in the shape of a Chinese character "mu";

[0063] Two side beams 2.3, which are symmetrically arranged on both sides of the first rectangular frame 2.1;

[0064] A cross beam 2.4, which is arranged between the two side beams 2.3;

[0065] A first diagonal brace 2.5, which is arranged between the side beam 2.3 and the U-shaped frame 2.2;

[0066] The second diagonal brace 2.6 is provided between the side beam 2.3 and the first rectangular frame 2.1.

[0067] Specifically, the U-shaped structure is used as the bottom side of the trapezoidal structure, the side beam 2.3 and the cross beam 2.4 form a U-shaped structure as the top side of the trapezoidal structure, the first diagonal brace 2.5 is used as the oblique side of the trapezoidal structure, and the second diagonal brace 2.6 is used as a reinforcing rib.

[0068] In this embodiment, a limiting bolt is also included. A plurality of first limiting holes 1.2 are provided on the periphery of the arc groove 1.1. A second limiting hole 1.3 is provided on the slider to match the first limiting holes 1.2. The limiting bolt is used to pass through the first limiting hole 1.2 and the second limiting hole 1.3.

[0069] Specifically, the second limiting hole 1.3 and the slider form a butterfly-shaped structure, and the limiting bolt locks the inclination angle of the rotating module 3 by passing through the first limiting hole 1.2 and the second limiting hole 1.3.

[0070] In this embodiment, the first limiting holes 1.2 are arranged in a staggered manner.

[0071] Specifically, the density of the adjustable inclination angle is increased by staggering the first limiting holes 1.2.

[0072] Furthermore, the first limiting holes 1.2 are arranged in two rows, with the first limiting holes 1.2 in each row spaced 4 degrees apart, and staggered 2 degrees between the two rows, thereby ensuring that the adjustable angle interval of the first limiting holes 1.2 is 2 degrees. This ensures adjustment accuracy and prevents the first limiting holes 1.2 from being too densely arranged, which would result in insufficient support strength.

[0073] In this embodiment, the first limiting holes 1.2 include a first hole close to the center side and a second hole away from the center side, and the first hole and the second hole are arranged in a group.

[0074] Specifically, the first hole and the second hole serve as backup for each other and are both used to pass through the limit bolts. The two sides of the slider are subjected to force respectively, which ensures the stability of the limit, improves safety, and avoids the danger of a single limit bolt breaking.

[0075] In this embodiment, the first half sleeve 5 is rotatably connected to the support module 2 .

[0076] Specifically, the first half sleeve 5 can be rotated to adjust the opening downward, eliminating the need for the rotating module 3 to move around. During use, the lifting module lifts the rotating module 3, allowing the rotating shaft 7 to approach and fit the first half sleeve 5 from bottom to top. The second half sleeve 6 is then connected to the first half sleeve 5 to form the first cylindrical structure.

[0077] In this embodiment, foot nail fixing holes 10 are provided on the upper portion of the U-shaped frame 2.2.

[0078] Specifically, the foot nail fixing holes 10 are used to cooperate with the foot nails for positioning and installation.

[0079] In this embodiment, a ground launch platform is used, taking assembly as an example:

[0080] The launch platform is modular in design, with each component weighing no more than 15kg. It can be transported separately and assembled uniformly, and each component is universal and can be fastened together using screws, bolts, buckles, and locks.

[0081] When assembling, first assemble support module 2 and secure it with the foot nails;

[0082] Install the lifting mechanism 4 so that the rotating module 3 is connected to the lifting mechanism 4, and the rotating module 3 is located at the lower end of the supporting module 2;

[0083] Fix the missile to the rotating module 3, lift the rotating module 3 and the missile to the top of the supporting module 2 through the lifting mechanism 4, and connect the two ends of the H-shaped frame to the first cylindrical structure and the second cylindrical structure respectively;

[0084] Adjust the angle of the rotating module 3 and fix it with a limit bolt.

[0085] While various embodiments of the present invention have been described above, the above description is intended to be illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
