Description

[0001] The utility model relates to unmanned aerial vehicles, namely to their mounting frames, and can be used to perform work by unmanned aerial vehicles.

[0002] A mounting frame for unmanned aerial vehicles (UAVs) is known. It comprises a ring frame on which operating equipment is mounted. Four locking devices are secured to the inner side. These devices are oriented in pairs toward each other and rest against the UAV, which is located in the center of the ring frame. Each locking device comprises a hollow, fixed section with a circular cross-section, rigidly attached to the ring frame. The fixed section is additionally equipped with mounting holes, and a vertical spring is inserted inside it. A movable plate-shaped section fits into the hollow, fixed section. One end of the plate rests on the vertical spring, and a locking plate, fitted with a rubber gasket on the inside, is rigidly attached to the free end of the movable section. The locking plate is pressed against the UAV.The movable section is equipped with horizontal openings on the sides, which accommodate horizontal springs, each spring being connected to a block aligned with a connecting slider. Each slider enters a mounting opening, securing the movable section. The ring frame is equipped with handles and rests on support posts (see CN Patent No. 221049947 U, IPC A 01 M 7 / 00, B 64 D 1 / 18, B 64 U 101 / 40, 101 / 45, 31.05.2024).

[0003] The disadvantage of this mounting frame for unmanned aerial vehicles is the low safety of work performed by unmanned aerial vehicles.

[0004] The task that the utility model is aimed at solving is improving the safety of work performed by unmanned aerial vehicles.

[0005] To solve this problem, in a mounting frame for unmanned aerial vehicles, including a ring frame on which the working equipment is installed and on the inner side there are four locking devices fixed, which are directed in pairs towards each other and rest against the unmanned aerial vehicle located in the center of the ring frame, where the ring frame is equipped with handles and rests on support posts, and each locking device contains a hollow fixed section rigidly fixed to the ring frame, a movable section enters into the hollow fixed section, at the free end of which a locking plate is rigidly fixed, equipped on the inside with a rubber gasket and pressed against the unmanned aerial vehicle, according to the utility model, each hollow fixed section is made of a rectangular cross-section, each movable section is made of a rectangular cross-section and has a threaded hole,into which the stud enters with one threaded end, the other free end of the stud has a diameter smaller than the diameter of the threaded end entering the movable section, and passes through a horizontal hole made in the annular frame and equipped with radial thrust bearings, the free end of the stud also has a short thread onto which a locking nut is screwed, and a diametrical hole.

[0006] The implementation of each hollow fixed section with a rectangular cross-section, each movable section with a rectangular cross-section, equipping each movable section with a threaded hole into which one threaded end of a stud enters, the other free end of the stud has a diameter smaller than the diameter of the threaded end entering the movable section, and passes through a horizontal hole made in the annular frame and equipped with radial thrust bearings, the free end of the stud has a short thread onto which a locking nut is screwed, and a diametrical hole, provides the ability to adjust the extension of the movable section from the hollow fixed section by means of the stud and, accordingly, the clamping force of the unmanned aerial vehicle in the locking devices, and eliminates the loosening of the locking devices under the action of dynamic loads, which can cause the fall of the unmanned aerial vehicle with the mounting frame.This increases the safety of work performed by unmanned aerial vehicles.

[0007] Fig. 1 shows a mounting frame for unmanned aerial vehicles, side view; Fig. 2 - the same, top view; Fig. 3 - section A-A in Fig. 2; Fig. 4 - unit B in Fig. 3.

[0008] The mounting frame for unmanned aerial vehicles includes an annular frame 1, on which working equipment 2 is installed, four locking devices 3 are fixed to the inner side of the annular frame 1, which are directed in pairs toward each other and rest against an unmanned aerial vehicle (not shown in the figure), located in the center of the annular frame. The annular frame 1 is equipped with handles 4 and rests on support posts 5. Each locking device 3 contains a hollow fixed section 6, rigidly fixed to the annular frame 1, a movable section 7 enters into the hollow fixed section 6, to the free end of which a locking plate 8 is rigidly fixed, equipped on the inside with a rubber gasket 9 and pressed against the unmanned aerial vehicle (not shown in the figure).Each hollow stationary section 6 is made of a rectangular cross-section, each movable section 7 is made of a rectangular cross-section and has a threaded hole into which one threaded end of the stud 10 enters. The other free end of the stud 10 has a diameter smaller than the diameter of the threaded end entering the movable section 7, and passes through a horizontal hole made in the annular frame 1 and equipped with radial thrust bearings 11. The free end of the stud 10 has a short thread onto which a fixing nut 12 is screwed, and a diametrical hole 13.

[0009] The installation of the mounting frame on the unmanned aerial vehicle is carried out on a level horizontal surface. The ring frame 1 with the working equipment 2 and the locking devices 3 is installed on the surface of the level horizontal surface on the support posts 5 using the handles 4. The unmanned aerial vehicle is installed in the center of the ring frame 1 between the locking plates 8 secured to the free ends of the movable sections 7 and equipped with rubber gaskets 9 on the inside. The locking nuts 12 are loosened and by rotating the studs 10 in the thrust-radial bearings 11, the locking plates 8 are pressed against the unmanned aerial vehicle by the rubber gaskets 9 due to the movement along the threads of the movable sections 7 relative to the hollow fixed sections 6. The studs 10 are driven into rotation by means of steel rods inserted into the diametrical holes 13 of the studs 10.Then tighten the fixing nuts 12 and check the fastening of the mounting frame to the unmanned aerial vehicle.

[0010] Removing the mounting frame from the unmanned aerial vehicle is performed as follows. The unmanned aerial vehicle with the mounting frame is landed on a level horizontal surface. Loosen the locking nuts 12 and, by rotating the studs 10 in the thrust-radial bearings 11, the locking plates 8 with rubber gaskets 9 are moved away from the unmanned aerial vehicle by moving the movable sections 7 along the threads relative to the hollow fixed sections 6. The unmanned aerial vehicle is then removed.

[0011] To lighten the mounting frame after removing the unmanned aerial vehicle, studs 10 with movable sections 7, fixing plates 8 and rubber gaskets 9 can be removed from the fixing devices 3, hollow fixed sections 6. To do this, unscrew the fixing nuts 12 and pull out the studs 10 with movable sections 7, fixing plates 8 and rubber gaskets 9 inside the annular frame 1. In this case, before installing the mounting frame on the unmanned aerial vehicle, studs 10 with movable sections 7, fixing plates 8 and rubber gaskets 9 are inserted from inside the annular frame 1 into a horizontal hole made in the annular frame 1 and equipped with radial thrust bearings 11. Fixing nuts 12 are tightened.

[0012] The use of the proposed mounting frame for unmanned aerial vehicles will ensure the safe performance of work by unmanned aerial vehicles.
