Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle maintenance, and in particular to a supporting device for unmanned aerial vehicle maintenance. Background Art

[0002] A drone is an unmanned aircraft controlled by a radio remote control device and a self-contained program control device. It is widely used in aerial reconnaissance, surveillance, communication, anti-submarine, electronic jamming, etc. When the drone is actually used, it needs to be repaired. In order to prevent the drone from shifting during the maintenance process, a supporting device is now often used to complete the fixed installation of the drone. In actual use, it has the advantages of simple operation, stable structure and good use effect.

[0003] The prior art discloses a carbon fiber drone maintenance fixing device with a publication number of CN214055024U, which includes a base, a top seat, a support rod and a movable rod. The base is provided with two spaced blocks, the blocks are provided with a slot, and a rubber layer is bonded in the slot. The legs of the drone are clamped in the slot to fix the legs and facilitate maintenance. The top seat is provided with a groove, and four threaded rods are connected in the groove. A center block is provided in the groove, and the four threaded rods are connected to the center block. A through hole is provided at the top of the movable rod for the threaded rod to pass through, and the position of the movable rod can be moved as needed to allow the wing of the drone to extend into the fixed sleeve. The threaded rod is screwed with a left nut and a right nut for clamping the movable rod, which play a role in fixing the movable rod. The bottom of the movable rod is connected to a fixed sleeve, and an annular airbag is bonded on the inner wall of the fixed sleeve. An air nozzle is provided on the annular airbag to facilitate the inflation and deflation of the annular airbag. When the annular airbag is in a deflated state, the position of the movable rod is moved to extend the wing of the UAV into the fixed sleeve. The fixed sleeve has a large diameter and does not affect the passage of the wind blades on the wing. The annular airbag is then inflated to squeeze and fix the wing. The position of the movable rod is then fixed, which will not cause squeezing damage to the wing. The fixing area is small, which is convenient for maintenance and improves maintenance efficiency.

[0004] In the above utility model, when fixing the wing of the drone, it is necessary to move it into the fixing sleeve, and then inflate the annular airbag inside the fixing sleeve. The inflated annular airbag can squeeze and fix the wing. This method requires the wing size to be smaller than the inner wall diameter of the fixing sleeve and the inner wall diameter of the annular airbag. When the wing size is larger, this installation method cannot be used, which reduces the practicality of this utility model.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a supporting device for drone maintenance, which has the following beneficial effects:

[0018] (1) The utility model adopts a connecting block. When the holding device for repairing a drone is actually used, the drone is placed on the bottom plate, and then the multiple sets of suction cups are moved by hand so that the multiple sets of suction cups are respectively adsorbed to the wings of the drone. Then, the control panel is used to shorten the electric telescopic rod, so that the lifting plate can pull the multiple sets of pull ropes to tighten the multiple sets of pull ropes. At this time, the wings of the drone are pulled and fixed by the pull ropes. When the drone needs to be disassembled, the operator opens and closes the multiple sets of first control valves by hand, and then blows air into the exhaust pipe. When the multiple sets of suction cups are filled with gas, the multiple sets of suction cups are separated from the wings of the drone. When the use length of the pull rope needs to be adjusted, the multiple sets of threaded through holes and the multiple sets of fastening bolts are used. The threads cooperate with each other, and the operator rotates the multiple sets of fastening bolts counterclockwise by hand. When the multiple sets of fastening bolts are separated from the multiple sets of pull ropes, the multiple sets of pull ropes can be moved. When the multiple sets of suction cups are moved to the appropriate position, the operator rotates the multiple sets of fastening bolts clockwise by hand. When the multiple sets of fastening bolts are in close contact with the multiple sets of pull ropes, the use length of the multiple sets of pull ropes is fixed. When the multiple sets of pull ropes move, the multiple sets of ball bearings are affected by friction and roll inside the multiple sets of ball sockets respectively. Since the surface of the multiple sets of ball bearings is smooth, the multiple sets of pull ropes can be prevented from being scratched by the connecting blocks. Through the set connecting blocks, wings of various sizes can be fixed and used, thereby improving the practicality of the holding device used for drone maintenance.

[0019] (2) The utility model adopts a mounting block. When the drone needs to be installed, the operator puts the drone on the bottom plate by hand, and then inserts one end of the air intake pipe into his mouth, and then opens and closes the second control valve. The operator blows air into the air intake pipe, and the gas can enter the interior of the two storage chambers through the air storage chamber and the two connecting pipes. This part of the gas can move the two piston plates, and the two piston plates can move the two contact plates away from each other through the two push rods. At the same time, the two piston plates stretch the two telescopic springs respectively. When the two contact plates contact the two brackets of the drone respectively, the second control valve is closed. The control valve completes the fixation of the UAV. When the UAV needs to be disassembled, the operator opens and closes the second control valve by hand. The two sets of telescopic springs, under the action of their own elastic force, will pull the two sets of piston plates to move toward each other for reset. The gas inside the two storage chambers can enter the gas storage chamber through the two sets of connecting pipes, and the gas inside the gas storage chamber is finally discharged through the air intake pipe. At this time, the resistance of the two sets of contact plates is lost, and the UAV can be removed. The set mounting block can be used to fix UAV brackets of various sizes, which brings convenience to the fixation of the UAV used for the UAV maintenance support device.

[0039] Working principle:

[0040] When the holding device for repairing a drone is actually used, the drone is placed on the bottom plate 1, and then the multiple groups of suction cups 6 are moved by hand so that the multiple groups of suction cups 6 are respectively adsorbed to the wings of the drone, and then the control panel is used to shorten the electric telescopic rod 12, so that the lifting plate 13 can pull the multiple groups of drawstrings 8 to tighten the multiple groups of drawstrings 8. At this time, the wings of the drone are pulled and fixed by the drawstrings 8. When the drone needs to be disassembled, the operator opens and closes the multiple groups of first control valves 10 by hand, and then blows air into the exhaust pipe 9. When the multiple groups of suction cups 6 are filled with gas, the multiple groups of suction cups 6 are separated from the wings of the drone respectively. When the use length of the drawstring 8 needs to be adjusted, the multiple groups of threaded through holes 15 and the multiple groups of fastening screws are used. The threads of the bolts 16 cooperate with each other, and the operator rotates the multiple sets of fastening bolts 16 counterclockwise by hand. When the multiple sets of fastening bolts 16 are separated from the multiple sets of pull ropes 8 respectively, the multiple sets of pull ropes 8 can be moved. When the multiple sets of suction cups 6 are moved to a suitable position, the operator rotates the multiple sets of fastening bolts 16 clockwise by hand. When the multiple sets of fastening bolts 16 are in close contact with the multiple sets of pull ropes 8 respectively, the use length of the multiple sets of pull ropes 8 is fixed. When the multiple sets of pull ropes 8 move, the multiple sets of balls 18 are subjected to friction and roll inside the multiple sets of ball sockets 17 respectively. Since the surfaces of the multiple sets of balls 18 are smooth, the multiple sets of pull ropes 8 can be prevented from being scratched by the connecting block 5. By setting the connecting block 5, wings of various sizes can be fixed. The use of the holding device for UAV maintenance improves the practicality of use. At the same time, when the UAV needs to be installed, the operator puts the UAV on the base plate 1 by hand, and then inserts one end of the air intake pipe 26 into his own mouth, and then opens and closes the second control valve 27. The operator blows air into the air intake pipe 26. The gas can enter the interior of the two storage chambers 20 through the air storage chamber 19 and the two connecting pipes 21. This part of the gas can move the two piston plates 22. The two piston plates 22 can move the two contact plates 24 away from each other through the two push rods 23. At the same time, the two piston plates 22 stretch the two telescopic springs 28 respectively. When the two contact plates 24 contact the two ends of the UAV respectively, the two contact plates 24 can move the two ends of the UAV. When assembling the bracket, close the second control valve 27 to complete the fixing of the UAV. When the UAV needs to be disassembled, the operator opens and closes the second control valve 27 by hand, and the two sets of telescopic springs 28, under the action of their own elastic force, will pull the two sets of piston plates 22 to move toward each other for reset. The gas inside the two sets of storage chambers 20 can enter the interior of the air storage chamber 19 through the two sets of connecting pipes 21, and the gas inside the air storage chamber 19 is finally discharged through the air intake pipe 26. At this time, the resistance of the two sets of contact plates 24 is lost, and the UAV can be removed. The installation block 3 is set, UAV brackets of various sizes can be fixed and used, which brings convenience to the fixed use of the UAV of the supporting device for UAV maintenance.
