Description

Technical Field

[0001] The utility model relates to the technical field of rotorcraft casing production, in particular to a rotorcraft casing protection support frame. Background Art

[0002] A gyroplane is a heavier-than-air aircraft that uses a non-powered rotor to provide lift. It is driven forward by a propulsion device, which includes a propeller and a jet. When it moves forward, the airflow blows the rotor to generate lift. It cannot take off vertically or hover. It often needs to give the rotor an initial power when taking off to increase the lift of the rotor. With the help of the rotor, it can make a nearly vertical landing. The rotor makes the structure complicated and the speed increase is limited.

[0003] Chinese patent publication number CN218949472U discloses a cargo autogyro, which has a main cargo hold and a lower cargo hold respectively disposed at the upper and lower parts of the fuselage, and the lower cargo hold disposed in the middle of the lower part of the fuselage, and the two cargo holds can increase the loading weight of the autogyro. The lower cargo hold controls the center of gravity of the autogyro below the middle part of the fuselage, and the center of gravity of the autogyro is more stable when carrying cargo.

[0004] However, compared with the prior art and comparative documents, the existing rotorcraft needs to prefabricate the shell during the production process, and then support and protect it through a support frame for subsequent use. However, during the support process, the support frame is mostly a double-layer structure. When the rotorcraft shell is placed below, it cannot be hoisted due to being blocked by the structure above the support frame. The staff is required to push the rotorcraft shell into the support frame. During the pushing process, the rotorcraft shell and the support frame rub against each other, causing the rotorcraft shell to wear and become damaged. In addition, the rotorcraft shell is currently supported by an arc-shaped bracket, but the rotorcraft shell is mostly an arc-shaped structure, and the size of the arc-shaped bracket will be larger than the size of the rotorcraft shell, resulting in a gap between the two, which makes it impossible to effectively fix and protect the rotorcraft shell, reducing the stability of the support. Utility Model Content

[0008] The stretching mechanism includes a slide groove fixed on the main frame, in which a slide rail is slidably connected, the slide groove is a hollow structure with an upper opening, a bearing seat is installed on the top of the slide rail, the bearing seat and the slide rail are connected by a connecting rod, and the connecting rods are all located on one side of the lower bracket. The top of the bearing seat is a symmetrical inclined structure, a magnetic suction plate is fixed at one end of the slide groove, and one end of the slide rail is attracted to the magnetic suction plate.

[0025] The stretching mechanism 4 includes a slide groove 401 fixed on the main frame 1, and a slide rail 402 is slidably connected in the slide groove 401. The slide groove 401 is a hollow structure with an upper opening. A bearing seat 403 is installed on the top of the slide rail 402. The bearing seat 403 and the slide rail 402 are connected through a connecting rod 4031. The connecting rod 4031 is located on one side of the lower bracket 3. The top of the bearing seat 403 is a symmetrical inclined structure. A magnetic suction plate 404 is fixed at one end of the slide groove 401, and one end of the slide rail 402 is attracted to the magnetic suction plate 404, which can be placed on the rotor casing below. When the body is in the state of being lifted up, the staff pulls the stretching mechanism 4, and the slide rail 402 can drive the supporting seat 403 to move out of the main frame 1 along the slide groove 401. By moving the supporting seat 403 to the outside of the main frame 1, the staff can place the rotorcraft shell on the supporting seat 403, and then push the supporting seat 403 back to make it reset along the slide groove 401 again and fix the slide rail 402 by the magnetic suction plate 404 at one end, so as to facilitate the taking and placing of the rotorcraft shell, and there is no need for the staff to push the rotorcraft, thereby preventing the rotorcraft from being damaged by friction with the main frame 1.

[0026] like Figure 1-Figure 2As shown, the upper bracket 2 and the lower bracket 3 have the same structure, both of which are arc-shaped structures, which facilitates the support of the rotorcraft casing through the upper bracket 2 and the lower bracket 3.

When placing the rotorcraft shell on the lower bracket 3, the staff pulls the stretching mechanism 4 with the handle 5, so that the slide rail 402 drives the bearing seat 403 to move out of the main frame 1 along the slide groove 401. By moving the bearing seat 403 to the outside of the main frame 1, it is convenient for the staff to place the rotorcraft shell on the bearing seat 403. After the placement is completed, the bearing seat 403 is pushed back to make it It is then reset along the slide groove 401 and fixed to the slide rail 402 by the magnetic suction plate 404 at one end, thereby facilitating the taking and placing of the rotorcraft casing, and there is no need for the staff to push the rotorcraft, thereby preventing the rotorcraft from being damaged by friction with the main frame 1. After the rotorcraft casing is placed, the staff can adjust the adjustment rods 601 in the limiting mechanisms 6 on both sides according to the size of the rotorcraft casing, so that the adjustment rods 601 drive the fastening pads 602 to abut against the rotorcraft casing, thereby clamping and fixing the rotorcraft casing for protection and improving the stability of the support.
