[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] A specific embodiment of this utility model provides an aerial heavy-load transfer device, combined with an attached... Figure 1 As shown, the device in this embodiment is mounted on a frame and mainly includes a lifting mechanism, a transfer mechanism, a walking mechanism, and a moving track 12. There are two sets of moving tracks 12, which are arranged in parallel and symmetrically on the top of the frame for the movement of the transfer mechanism.

[0034] A transfer mechanism is provided on the moving track 12. The transfer mechanism includes a transfer frame 6, a second motor 7, a first transmission device, and a rotating wheel. In this embodiment, the transfer frame 6 is a rectangular frame with rotating wheels at the four corners. The second motor 7 is mounted on the transfer frame 6. The first transmission device is connected to the output end of the second motor 7 and the rotating wheel respectively. The rotation of the second motor 7 can drive the rotating wheel to rotate through the first transmission device, so that the rotating wheel moves along the track on the moving track 12.

[0035] The traveling mechanism is located below and connected to the transferring mechanism. The traveling mechanism includes a traveling frame 8, a third motor 9, a second transmission device, a sprocket 10, and a chain 11. One end of the traveling frame 8 is fixedly connected to the transferring frame 6. The third motor 9 is located on the top of the traveling frame 8. The second transmission device connects the third motor 9 and the sprocket 10. The sprocket 10 and the chain 11 are meshed together. The output end of the third motor 9 rotates and is transmitted to the sprocket 10 through the second transmission device, thereby driving the sprocket 10 to rotate. The sprocket 10 drives the chain 11, which in turn drives the lifting mechanism to complete the lifting movement on the traveling mechanism.

[0036] The lifting mechanism and the traveling mechanism are adjustablely connected and located inside the traveling mechanism. The lifting mechanism includes a lifting frame 2, a first motor 3, a transmission rod, a rotating support arm 4, and a counterweight 5. The first motor 3, the transmission rod, and the rotating support arm 4 are located on the front side of the lifting frame 2, and the counterweight 5 is located on the rear side of the lifting frame 2. The two ends of the transmission rod are connected to the first motor 3 and the rotating support arm 4, respectively. A slide groove is provided inside the traveling frame 8. The lifting frame 2 and the slide groove are adjustablely connected. The movement of the chain 11 can drive the lifting frame 2 and the counterweight 5.

[0037] Specifically, a chain connecting screw is provided at the top of the lifting frame 2, which is connected to the chain 11. The lifting frame 2 is guided by a sprocket 10 on the side for overall lifting. Two rotating support arms 4 are provided as a group; in this embodiment, at least two groups are provided. The two rotating support arms 4 are symmetrically arranged at both ends of the front side of the lifting frame 2. The rotating support arms 4 are connected to the rotating shaft of the lifting frame 2, allowing the rotating support arms 4 to adjust the swing arm support direction by rotating the shaft. A first motor 3 is fixed to the lifting frame 2 between the rotating support arms 4. A diamond-shaped flange 31 is provided at the output end of the first motor 3, with the center of the diamond-shaped flange 31 connected to the output end of the first motor 3. Connecting holes 3 are provided at both ends of the diamond-shaped flange 31. 2. The connecting hole 32 is used for the installation and fixing of the transmission rod; the transmission rod includes a first transmission rod 33 and a second transmission rod 34, which are located on the outside of the rotating arm 4 shaft; the output end of the first motor 3 rotates to drive the diamond flange 31 to rotate and adjust, and the connecting hole 32 on the diamond flange 31 is connected to the first transmission rod 33 and the second transmission rod 34. The frictional movement of the first transmission rod 33 and the second transmission rod 34 drives the rotating arm 4 shaft to rotate, so that the rotating arm 4 can adjust the support direction horizontally, and return to the initial position after the transition is completed; in a feasible embodiment, a proximity switch is also provided at the bottom of the walking frame 8, which can detect the position of the swing arm rotation.

[0038] Specifically, the traveling mechanism includes a traveling frame 8, a third motor 9, a second transmission device, sprockets 10, and chains 11. The traveling frame 8 has four uprights 51, which are connected and fixed together by crossbeams to form a support frame. The second transmission device includes a second universal coupling 52, a second flange 53, and a corner joint 54. Two third motors 9 are symmetrically arranged on the crossbeams. The output end of each third motor 9 is connected to the second flange 53 and one end of the second universal coupling 52. The other end of the second universal coupling 52 is connected to the corner joint 54. The four uprights 10, 11, and 11 are mounted on the crossbeams. The column 51 and crossbeam provide the frame for the entire component. Driven by the third motor 9, the transmission is transmitted to the sprocket 10 through the second universal coupling 52, the second flange 53, and the corner joint 54. The sprocket 10 is connected to the lifting frame 2 at one end and to the counterweight 5 at the other end via the chain 11, enabling the lifting frame 2 to perform lifting functions. The counterweight 5 balances the weight, increases the system load, and reduces the required motor power. One end of the column 51 is connected to the transfer mechanism and can move with the transfer mechanism. The traveling frame 8 is also equipped with a cable chain mounting bracket 55 for supporting the cable chain of the traveling mechanism's wiring harness.

[0039] Specifically, the transfer mechanism includes a transfer frame 6, a second motor 7, a first transmission device, and a rotating wheel. The rotating wheel includes a drive wheel 44 and a driven wheel 45. The first transmission device includes a first universal coupling 41, a first flange 42, and a seated bearing 43. Rotation is provided at the four corners of the transfer frame 6, with the drive wheel 44 on one side and the driven wheel 45 on the other side. The second motor 7 is fixed on the transfer frame 6 on the side where the drive wheel 44 is located. The output end of the second motor 7 is provided with the first flange 42 and connected to one end of the first universal coupling 41. The other end of the first universal coupling 41 is connected to the seated bearing 43, and the transmission is transmitted to the drive wheel 44 through the seated bearing 43. The integral transfer frame 6 is provided by profile welding and is driven by the second motor 7. The transmission is transmitted to the drive wheel 44 through the first flange 42 and the first universal coupling 41, so that the entire transfer mechanism can move linearly in the x-axis direction on the moving track 12 and drive the entire transfer device to move.

[0040] The working principle and advantages of the device in this embodiment:

[0041] The lifting frame 2 is lowered to its lowest position, and the rotating support arm 4 retracts and waits. When the vehicle (skateboard or skid) brings the car body into the transfer area, the rotating support arm 4 extends, the lifting frame 2 rises at low speed, and then rises at high speed after taking the car body away from the vehicle. At the same time, the transfer mechanism is activated, which moves the car body to the transfer position of the next line. After decelerating and stopping, the lifting frame 2 descends and transfers the car body to the vehicle of the new line. The support arm retracts and moves back to the initial position through the transfer mechanism.

[0042] The system uses a counterweight and lifting frame for aerial lifting, which, compared to the existing scissor lift (prone to swaying) and cam lift (small lifting stroke, prone to shaft breakage) used in the towing device, has a larger load capacity (3 tons) and greatly improved stability.

[0043] Using a corner mechanism for transmission allows both sides to lift and lower synchronously, eliminating the need for separate control by two motors;

[0044] Unlike belt drives, chains offer greater stability and eliminate the elastic deformation that occurs in belts during lifting and transplanting under heavy loads.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
