[0021] The technical solution of the present utility model is further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present utility model is not limited to the following.

[0022] like Figures 1 to 3 As shown, a fixed bracket for troubleshooting and repairing unmanned aerial vehicles includes a rotating device and a clamping device. The rotating device can be designed with reference to an engine inspection and lifting frame for automobile maintenance (if the size of the unmanned aerial vehicle to be inspected and repaired is suitable, the existing engine inspection and lifting frame can be directly used for modification). Its structure includes a column 1, a turntable 2 and a rotating handwheel 3. A meshing worm gear and a worm are arranged inside the top of the column 1. The rotating handwheel 3 is fixedly connected to one end of the worm gear. The turntable 2 is coaxially fixedly connected to the worm gear. Rotating the rotating handwheel 3 can drive the worm gear to rotate, and then drive the turntable 2 to rotate through the worm gear. At the same time, under the action of the worm gear mechanism, the rotating handwheel 3 can be self-locked when the rotation stops.

[0023] The clamping device comprises a carriage 4, a first screw rod 5 and two swing mechanisms. The swing mechanism comprises a first slider 6, a swing rod 7 and a support rod 8. One end of the swing rod 7 is rotatably connected to the first slider 6. The support rod 8 is fixedly connected to the other end of the swing rod 7. The support rod 8 is arranged parallel to the horizontal direction. A plurality of clamping members are arranged on the support rod 8. The rod bodies of the two swing rods 7 are rotatably connected. The two first sliders 6 are both slidably connected to the carriage. The two swing mechanisms are combined to form a scissor-type structure. When the two first sliders 6 are brought closer to each other, the two support rods 8 are moved away from each other. The carriage 4 is arranged on the turntable 2. The first screw rod 5 is rotatably arranged on the carriage 4. The threads at both ends of the first screw rod 5 are rotated in opposite directions. The two ends of the first screw rod 5 are respectively threadedly connected to the two first sliders 6. Rotating the first screw rod 5 can drive the two first sliders 6 to approach or move away from each other.

[0024] When the fixed bracket for troubleshooting and repairing unmanned aerial vehicles is used, the first screw rod 5 is first rotated to make the distance between the two support rods 8 match the distance between the bottom ends of the two U-shaped pipe racks at the bottom of the unmanned aerial vehicle; then the unmanned aerial vehicle is placed on the two support rods 8 (the two support rods 8 are located inside the two U-shaped pipe racks); then the first screw rod 5 is rotated to make the two first sliders 6 move away from each other, drive the two support rods 8 to move outward to tighten the two U-shaped pipe racks outward, and connect the bottom end of the U-shaped pipe with the support rods 8 through the clamping member. In specific implementation, the clamping member includes an upper clamping seat 11 and a lower clamping seat 12, the lower clamping seat 12 is connected to the support rod 8, the upper clamping seat 11 and the lower clamping seat 12 are connected by screws, and semicircular holes that match each other are opened on the ends where the upper clamping seat 11 and the lower clamping seat 12 are connected, and the two semicircular holes can be buckled into a circular hole, and after a rubber sheet is installed therein, the straight pipe section at the bottom end of the U-shaped pipe rack can be directly and effectively clamped. Thus, the drone and the clamping device can be stably connected, and the drone can be turned over by turning the rotating hand wheel 3, so that when troubleshooting and repairing the entire drone, the troubleshooting or repair area can be facing the operator, making the operation more convenient.

[0025] In the above arrangement, the support rod 8 is in the form of a cantilever. The two support rods 8 can be connected to the two U-shaped pipe frames at the bottom of the drone by tensioning outwards and clamping with the clamping parts, so that the drone can be effectively fixed. It can also effectively avoid bumping the drone rotor during the flipping process. There is also enough operating space between the two support rods 8 when inspecting and repairing the belly area of ​​the drone. The above scissor-type structure design can be used to fix drone tripods of different widths and has a wide range of applications. At the same time, the drone troubleshooting and maintenance fixing bracket can be retracted to the bottom when not in use. Figure 2 The illustrated configuration prevents the two support rods 8 from spreading outwards and occupying space.

[0026] Furthermore, a support tube 9 is sleeved on the support rod 8, and the aforementioned clamp is arranged on the support tube 9. On the one hand, the support tube 9 can slide on the support rod 8, extending the cantilever support size to be suitable for use with drones of different wingspans; on the other hand, the support tube 9 can rotate on the support rod 8 to facilitate adjustment of the direction of the clamp, so as to facilitate connection of the support tube 9 with the U-shaped pipe frame at the bottom of the drone through the clamp. In specific implementation, a locking screw 10 is threadedly connected to the support tube 9, and one end of the locking screw 10 is connected to a friction rubber sheet, which can pass through the tube wall of the support tube 9 and abut against the support rod 8. Tightening the locking screw 10 can make the support tube 9 and the support rod 8 relatively fixed.

Therefore, when clamping and fixing drones of different heights and sizes, the position of the drone can be adjusted by rotating the second screw, so that the geometric center of the drone is basically aligned with the rotation center of the turntable 2, avoiding large eccentricity when flipping the drone for troubleshooting and maintenance.

[0028] In a specific implementation, a fixing frame is fixedly provided on the end of the turntable 2 away from the worm gear, and the second screw 14 is rotatably provided on the fixing frame. A guide rod 15 is fixedly provided on the fixing frame, and the guide rod 15 is parallel to the second screw 14.
