However, the fixing support is manufactured by reusing the existing car engine maintenance rack, and since the height between the rotating disc and the tool disc is fixed, and the unmanned plane is supported in a cantilevered manner after being clamped, the fixing support can only be used for the maintenance of the unmanned plane within a certain size range and weight, and it is not suitable for the maintenance of the unmanned plane with a size or weight that is too large.

DETAILED DESCRIPTION

[0019] The technical scheme of the utility model will be described in further detail below in combination with the drawings, but the protection scope of the utility model is not limited to the following description.

[0020] As Figs. 1 to 4As shown, a UAV maintenance lifting clamping device comprises a clamping mechanism. The clamping mechanism comprises a screw rod 1 and two clamping assemblies, each of which comprises a clamping block 2, a clamping strip 3 and a locking nut 4. One side of the clamping strip 3 is inwardly machined with a limiting groove 5 and a clamping groove 6 in sequence. The cross section of the limiting groove 5 is rectangular, and the cross section of the clamping groove 6 is V-shaped. Both ends of the limiting groove 5 and the clamping groove 6 penetrate through both ends of the clamping strip 3. The top surface center of the clamping strip 3 is rotatably connected with the clamping block 2. The clamping block 2 is movably sleeved on the screw rod 1. The rotation axis of the clamping strip 3 relative to the clamping block 2 is perpendicular to the axis of the screw rod 1. The locking nut 4 is threadedly connected with the screw rod 1. Two locking nuts 4 are respectively adapted to the sides of the two clamping blocks 2 away from each other.

[0021] The lower part of the existing UAV is generally provided with two foot supports (U-shaped tube supports) for support. The above-mentioned clamping mechanism is used to clamp the foot supports of the UAV. The clamping groove 6 is adapted in size to the foot supports of the UAV. In operation, first, the two foot supports of the UAV are respectively clamped into the limiting grooves 5 and the clamping grooves 6 of the two clamping strips 3. Then, the angles and positions of the two clamping blocks 2 are adjusted, and the screw rod 1 is sequentially threaded through the two clamping blocks 2. After that, the two locking nuts 4 are threadedly tightened at both ends of the screw rod 1. When the two locking nuts 4 are tightened, the two clamping blocks 2 are pressed towards each other. In this process, the two clamping strips 3 can press and clamp the two foot supports of the UAV towards each other to complete clamping. In this clamping process, since the cross section of the clamping groove 6 is V-shaped and the clamping groove 6 has a certain length, as the two locking nuts are tightened, the clamping strip 3 can rotate and adaptively adjust the angle relative to the clamping block 2, so that when clamping is completed, the clamping strip 3 is parallel to the clamped steel pipe section of the UAV foot support, and the steel pipe sections at the clamped positions of the two foot supports of the UAV are completely clamped into the two limiting grooves 5 and the clamping grooves 6. The six degrees of freedom between the UAV foot supports and the clamping mechanism are all limited (in specific implementation, rubber pads are also provided in the two clamping grooves 6 to provide sufficient frictional resistance to the relative sliding of the clamping strip and the UAV foot supports when clamping), ensuring stable clamping.

[0022] It should be understood that the structure of the foot stand of the unmanned aerial vehicle is different according to the model of the unmanned aerial vehicle, and the clamping mechanism can be applied to the clamping of unmanned aerial vehicles with different foot stand structures. For example, when the unmanned aerial vehicle is placed, the bottom steel pipes of the two foot stands are approximately parallel, but the side steel pipes of the two foot stands are in an outwardly open eight-shaped structure. The clamping mechanism described above can be used for clamping the positions of the bottom steel pipes of the two foot stands, and can also be used for clamping the positions of the side steel pipes of the two foot stands. It should also be understood that for unmanned aerial vehicles that are too heavy, multiple clamping mechanisms described above can be provided to achieve multi-point clamping of different positions of the foot stand of the unmanned aerial vehicle. Then, the screws 1 of the multiple clamping mechanisms are connected (for example, two screws 1 can be connected by a connecting plate with a long slot. When connected, a connecting nut is first screwed onto the screw 1, then the screw 1 is passed through the long slot, and then another connecting nut is screwed onto the screw 1. Tightening the two connecting nuts in the direction of the connecting plate can connect the screw and the connecting plate). This can ensure stable clamping.

[0023] The clamping mechanism, as an external tool, can be fixedly connected with the foot stand of the unmanned aerial vehicle during maintenance of the unmanned aerial vehicle, so that external equipment can drive the unmanned aerial vehicle to perform functions such as lifting and turning through the clamping mechanism. In implementation, two elongated sleeves 7 are further included. One end of the elongated sleeve 7 is provided with an internal thread, and the two elongated sleeves 7 are directly threadedly connected to the two ends of the screw 1 to lengthen the device as a whole. After the device is lengthened, it can be directly lifted by an electric hoist. When lifting, the bottom end of the steel rope is hung on the two elongated sleeves 7 to make the steel rope away from the body, rotor and rotor arm of the unmanned aerial vehicle, so as to avoid damage to the unmanned aerial vehicle during lifting. Through lifting, the unmanned aerial vehicle can also be kept away from the ground, which is convenient for maintenance of the abdominal area of the unmanned aerial vehicle.

[0024] In specific implementation, two upright columns 8 are further provided on the maintenance site. The top end of the upright column 8 is provided with a V-shaped groove 12. After the unmanned aerial vehicle is lifted as described above, the two elongated sleeves 7 can be placed and erected in the two V-shaped grooves 12 respectively. The two upright columns 8 simply support the unmanned aerial vehicle, which is lifted away from the ground, so as to facilitate maintenance of the unmanned aerial vehicle. At the same time, this simple support form is suitable for lifting and supporting of a larger unmanned aerial vehicle.

[0025] Further, a base column 9 and a positioning pin 10 are further included. The upright column 8 is slidably connected with the base column 9. A plurality of positioning holes are formed in the upright column 8 and the base column 9 in the vertical direction, and the positioning pin 10 is adapted to the positioning holes. The base column 9 can be placed on the ground. The height of the V-shaped groove 12 can be adjusted by sliding the upright column 8 up and down. After the height adjustment is completed, the positioning pin 10 is passed through one positioning hole of the upright column 8 and one positioning hole of the base column 9, so as to relatively fix the upright column 8 and the base column 9. Thus, this design can adjust the support height of the upright column 8 for the unmanned aerial vehicle, and is suitable for maintenance of a larger unmanned aerial vehicle.

[0026] Further, the limiting disc 11 and the limiting pin 13 are further included. The limiting disc 11 is sleeved on one end of the lengthened sleeve 7 away from the screw rod 1. In the implementation, the end of the lengthened sleeve 7 is processed with a key groove, and the limiting disc 11 is connected with the lengthened sleeve 7 through the key. The limiting pin 13 is detachably sleeved on one stand 8. The limiting disc 11 is uniformly distributed with a plurality of notches on the outer periphery. The limiting pin 13 is matched with the notches. When the two lengthened sleeves 7 are hoisted and erected in the two V-shaped grooves 12, the end face of the limiting disc 11 is close to the stand 8. After the erection is completed, the limiting disc 11 can be rotated to drive the unmanned aerial vehicle to overturn by a certain angle. The unmanned aerial vehicle can make the maintenance surface (for example, the belly of the body) face the operator to facilitate the maintenance. When the overturning is completed, the limiting pin 13 is inserted into the stand 8. Through the rod body of the limiting pin 13, the limiting pin 13 is clamped in the notches of the limiting disc 11, so that the positioning after the overturning is completed.
