Description

Technical Field

[0001] The utility model relates to the technical field of brackets, in particular to a drone transportation bracket. Background Art

[0002] UAVs are increasingly widely used in various fields such as logistics, mapping, power inspection, and disaster prevention. UAVs are also developing towards large-scale and multi-functional. Generally, when a UAV is delivered to a customer, due to technical limitations such as flight range and communication, during transportation, after the UAV is disassembled, it is transported to the customer by ground transportation and then assembled. In addition, before leaving the factory, the UAV needs to be tested for normal functions. Each system is turned on to conduct an aging test to evaluate the integrity of each system.

[0003] During the aging test of the UAV, the UAV needs to be fixed on an aging test bench. After running the power system to its boundary for a period of time, the functions of each system are evaluated. During transportation, each section is removed and fixed to a transport vehicle through a designed bench. Each section of the UAV is transported to the customer through a bracket, and different structures of the fuselage are fixed on different brackets. However, many existing transportation brackets are too complex and heavy in structure and have a high cost. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a drone transportation bracket to solve the problems mentioned in the background art. To achieve the above purpose, the utility model provides the following technical solution: A drone transportation bracket includes a platform, on which four columns are installed. The columns are divided into two groups and installed on the platform. Wing surface fixing blocks are installed between the columns on the same side, and a fixer is installed at the top of the columns.

[0005] Preferably, a diagonal brace is installed between the column and the platform, and casters are installed at the bottom of the platform.

[0006] Preferably, the platform, columns, and diagonal braces are all welded by profiles.

[0007] Preferably, the distance between the columns on one side is greater than the diameter of the propeller.

[0008] Preferably, the wing surface fixing block includes two retaining edges, which are respectively connected to the columns on both sides. A clamping plate is inserted between the two retaining edges. The clamping plate includes a plurality of sub-plates, and wing surface grooves are formed on the sub-plates.

[0009] Preferably, the fixer includes a base. One side of the top of the base is rotatably connected to one end of a clamp through a rotating shaft. The other end of the clamp is connected to the other side of the base through a fastener, and the base is fixedly installed on the base.

[0010] Technical effects and advantages of the present utility model: The bracket takes up little space. The distance between the two columns is greater than the distance of the propeller diameter, so that the propellers on the wing can be arranged along the front-back direction of the transfer bracket, reducing the size in the width direction and enabling transportation in a standard container.

[0011] Multiple functions: Before the UAV leaves the factory, the transportation bracket can be used as an aging test bench. The UAV is fixed on it, the power system is turned on, and an aging test is carried out to ensure the normal operation of the propeller, battery, motor, etc.

[0012] Effectively protect the airframe: For the structure with relatively thin skin thickness of the wing and tail, foam cardboard is used for fixation to prevent damage to the skin and effectively protect the airframe.

[0013] Low cost: It is assembled by standard industrial aluminum profiles. The wing and tail are fixed by cutting soft foam to fix the UAV, with relatively low cost. Description of the drawings

In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection or a mechanical connection, and it can also be an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and the interiors of two components can be communicated.

[0021] Embodiment

[0022] As Figure 1 shown, when the UAV transport bracket is used as an aging test bench, the UAV 2 is installed on the transport bracket 1 in a whole-machine state and fixed by multiple fixators. In this example, there are 4 fixators. Weights are added on the platform of the transport bracket 1 for ballasting. Then the UAV 2 is turned on and run for a period of time to ensure the normal function of each system. The weights are added to prevent the transport bracket 1 from being dragged off the ground when the UAV 2 is running.

[0023] As Figure 2 shown, when the UAV transport bracket is used as a device for fixing and transporting the UAV, the UAV 2 is disassembled into the fuselage 21, the wings 22 and the tail 23, and they are respectively fixed to the corresponding parts of the transport bracket 1. To save space, the fuselage 21, the wings 22 and the tail 23 are arranged in a three-dimensional space, and a safe distance is ensured between each component to prevent the components from colliding with each other due to vibration, bumps, etc. during transportation. There are requirements for the placement order. The wings 22 and the tail 23 must be fixed first, and then the fuselage 21 can be placed. If the fuselage 21 is placed first, the wings 22 cannot be placed on the transport bracket 1.

[0024] As Figure 3 shown, the transport bracket 1 includes a platform 11, columns 12, fixators 13, wing surface fixing blocks 14 and diagonal braces 15. The columns 12 are installed on the platform 11. There are four columns 12, which are divided into two groups and installed on the platform 11. Wing surface fixing blocks 14 are installed between the columns 12 on the same side; the platform 11, the columns 12 and the diagonal braces 15 are all welded by industrial aluminum profiles. Casters are installed at the bottom of the platform, which can be easily pushed on the ground, saving manpower. The columns 12 raise the height for fixing the fuselage 21. The fixators 13 are connected to the tops of the columns 12. The distance between the columns 12 on the same side is greater than the diameter of the propeller. In this way, when the wings 22 are placed, the propeller can be placed along the length direction of the transport bench and does not interfere with the transport bracket, preventing the propeller from being damaged. The fixators 13 are connected to the four motor arms of the fuselage 21 to fix the fuselage 21, ensuring that the fuselage 21 is firmly fixed and meeting the strength requirements during the aging test. The diagonal braces 15 play a strengthening role to ensure the stability and firmness of the columns 12.

[0025] As Figure 4As shown in the figure, the wing fixing block 14 includes a retaining edge 141 and a clamping plate 142. The retaining edge 141 is welded to the column 12 with an aluminum alloy plate, forming a groove with a certain width inside. The width of the clamping plate 142 is slightly wider than the width of the groove formed by the retaining edge 141. In this example, it is 3 mm. The clamping plate 142 is processed from low-density foam and can be inserted into the groove of the retaining edge 141. There is a certain frictional force between it and the groove to maintain fixation. It can be seen that the clamping plate 142 is composed of multiple sub-plates. Through assembly, the wing 22 is clamped inside the clamping plate 142 to ensure the fixation of the wing 22. At the same time, the position where the clamping plate 142 contacts the wing surface is also hollowed out according to the shape of the wing surface to form a wing surface groove 143 to protect the airframe structure.

[0026] As Figure 5 shown in the figure, the fixer 13 includes a clamp 131, a rotating shaft 132, and a base 133. The base 133 is fixed to the column 12, which can be fixed by fasteners or by welding. In this example, fasteners are used for fixation. The clamp 131 clamps the motor arm of the airframe structure. One side is connected to the base 133 through the rotating shaft 132 and can move around the rotating shaft 132, which is convenient for the installation, fixation, and disassembly of the airframe structure. The other side of the clamp 131 is connected to the base 133 by fasteners. When the airframe is fixed, the clamp 131 and the base 133 are connected together by fasteners to ensure a reliable connection. When disassembly is required, just unscrew the fasteners.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
