[0017] like Figure 1-4 As shown, the present invention provides an automatic fixing device for aircraft wheels, including a wheel 71, a support block 72, a support frame 73 and a wheel stopper 6, wherein the two wheels 71 are symmetrically arranged on both sides of the support frame 73, and the support block 72 is arranged in the middle of the bottom of the support frame 73, and further includes a frame 4, a guide wheel group 3, a positioning mechanism, a running wheel 5 and a pick-and-place mechanism, wherein the positioning mechanism is installed in the middle of the top of the frame 4, the guide wheel group 3 is arranged on both sides of the frame 4, the pick-and-place mechanism is symmetrically arranged on the front and rear sides of the frame 4, and the pick-and-place mechanism includes a motor 1 1. Connecting rod 12, manipulator mechanism and connecting block 16. The connecting block 16 is vertically fixed on the wheel chock 6. The four connecting rods 12 are symmetrically pivoted to the front and rear sides of the frame 4. The motor 11 is installed on the frame 4. The motor 11 drives the connecting rod 12 to rotate around the pivot point between the connecting rod 12 and the frame 4. The extended end of the connecting rod 12 is fixedly connected to the manipulator mechanism. The motor 11 drives the connecting rod 12 to drive the manipulator mechanism to approach or move away from the connecting block 16. The manipulator mechanism completes the picking and placing of the wheel chock 6 by clamping or releasing the connecting block 16.

[0018] The manipulator mechanism includes a fixed plate 13, a movable plate 14 and an electric cylinder 15. The fixed plate 13 is fixedly connected to the protruding end of the connecting rod 12. The cylinder body of the electric cylinder 15 is fixed on the fixed plate 13. The protruding end of the electric cylinder 15 is fixedly connected to the movable plate 14. The electric cylinder 15 drives the movable plate 14 so that the movable plate 14 and the fixed plate 13 clamp or release the connecting block 16.

[0019] The positioning mechanism includes a spring telescopic column 21, a cross plate 22 and a positioning groove 23. The cross plate 22 is installed above the frame 4 through multiple spring telescopic columns 21. The positioning groove 23 is opened in the middle of the top of the cross plate 22. The positioning groove 23 matches the shape of the support block 72. When the spring telescopic column 21 is in a natural state, the top of the cross plate 22 is higher than the lowest point of the support block 72.

[0020] The guide wheel group 3 includes a plurality of rollers, which are arranged on the side of the frame 4 along the moving direction of the frame 4 , and the rollers are vertically arranged and rotatably connected to the frame 4 .

[0021] Mounting grooves are provided on both sides of the vehicle frame 4 , and the guide wheel groups 3 are arranged in the mounting grooves and partially exposed, and the outermost spacing of the guide wheel groups 3 on both sides is equal to the spacing of the inner sides of the two wheels 71 .

[0022] A plurality of running wheels 5 are symmetrically rotatably connected to both sides of the bottom of the frame 4 .

[0023] When it is necessary to place wheel chocks 6 on the front and rear sides of the aircraft wheels 71, the device is first operated to move between the two wheels 71 through the running wheels 5, and the guide wheel groups 3 on both sides of the frame 4 contact the inner sides of the wheels 71 on both sides respectively, so as to correct the forward direction of the frame 4. At this time, the cross plate 22 begins to be pushed downward by the support block 72, the spring telescopic column 21 is compressed, and the frame 4 continues to move forward. When the bottom of the support block 72 extends into the positioning groove 23, the frame 4 stops moving, and the motor 11 starts working, and the motor 11 drives the connecting The connecting rod 12 rotates toward the wheel 71 on the same side, and the connecting rod 12 drives the fixed plate 13, the movable plate 14, the electric cylinder 15, the connecting block 16 and the wheel chock 6 connected to the connecting block 16 to move. When the wheel chock 6 moves to the front or rear side of the wheel 71, the motor 11 stops working, the extended end of the electric cylinder 15 extends outward, and the movable plate 14 is pushed up. At this time, the connecting block 16 is no longer clamped by the fixed plate 13 and the movable plate 14, and the wheel chock 6 is stably placed on the ground and detached from the device, and then the connecting rod 12 is restored by the motor 11. When the wheel chock 6 needs to be removed, the previous operation is repeated. When the movable plate 14 and the fixed plate 13 are driven to the two sides of the corresponding connecting block 16 by the connecting rod 12, the extended end of the electric cylinder 15 is retracted, so that the fixed plate 13 and the movable plate 14 clamp the connecting block 16, and then the motor 11 drives it to return to the initial posture, and then drives away from the support frame 73. The device can be operated by the motor 11, the connecting rod 12, the fixed plate 13, the movable plate 14, the electric cylinder 15 and the connecting rod 12. The setting of block 16 automatically places or removes the wheel chocks 6 on the front and rear sides of the wheel 71, thereby completing the fixing and releasing of the aircraft wheel 71. The device can also enable the frame 4 to more accurately move to the bottom of the support frame 73 through the setting of the spring telescopic column 21, the cross plate 22 and the positioning groove 23 to complete the precise placement of the wheel chocks 6 on the front and rear sides of the wheel 71, so that the wheel 71 can be fixed more reliably. The device can also provide an auxiliary positioning function through the setting of the guide wheel group 3 to help the device complete its work more smoothly.
