[0043] Example

[0044] First, as Figures 1 to 4 As shown, an embodiment of the present invention provides an adaptive stacking wheel transfer hanger, including a clamp body 3, two outer frame components rotatably arranged on the clamp body 3 and used to cooperate to clamp the stacking wheels located on the stacking platform 8, and a first driving mechanism connected to the two outer frame components and used to control the two outer frame components to rotate, the outer frame components include a clamp outer frame 7 and a clamping mechanism arranged on the clamp outer frame 7, and the clamping mechanisms on the two outer frame components cooperate to clamp the stacking wheels.

[0045] Specifically, if Figures 1 to 4 As shown, a truss connection flange 1 is provided at the upper end of the clamp body 3, and the upper end of the clamp body 3 is connected to the movable truss through the truss connection flange 1. The clamp outer frame 7 is connected to the clamp body 3 through a rotating shaft, and the outer frame driving motor 10 is connected to the outer frame driving rods 11 on the left and right sides through a coupling rod 12, fixed by a fixing pin 15 and a bayonet pin 14, and the outer frame driving rod 11 is connected to the outer frame upper ear through a shaft.

[0046] The upper and lower ends of the clamping rod 6 are fixedly connected to a slider that can move on the inner rod guide transmission integrated rod 5A and the guide rod, and the upper end is also fixedly connected to a slider that slides on the outer frame rotating rod 4. The inner rod driving motor 16 drives the inner rod guide transmission integrated rod 5A on the left and right sides to rotate through the pulley 17.

[0047] The clamp body 3 is a square structure, with shaft sleeves 19 and bearings installed at both ends to match the inner rod guide transmission integrated rod 5A. The inner rod guide transmission integrated rod 5A can rotate with both sides as fulcrums. The clamp body 3 is provided with a mounting base for the outer frame drive motor 10 and the inner rod drive motor 16, and is equipped with a protective cover 2.

[0048] There are two clamp outer frames 7, and the clamp outer frames 7 are of a square frame structure. The clamp body 3 is located between the two clamp outer frames 7. An outer frame middle ear 7_1 is provided in the middle of the upper end of the clamp outer frame 7, and outer frame side ears 7_2 are provided on both sides of the upper end of the clamp outer frame 7. An outer frame lower support 7_3 is provided at the lower end of the clamp outer frame 7. Both sides of the inside of the clamp outer frame 7 have threads for installing the outer frame rotating shaft, and the outer frame side ears 7_2 are connected to the clamp body 3 through the shaft sleeve 19.

[0049] A single sling has four clamping rods 6, two of which are symmetrically arranged on the left and right. The clamping rod 6 is cylindrical, and the inner and outer sides of the upper end have a structure that is fixedly connected to the inner rod middle slider 13 and the inner rod upper slider 9 through threads, and the outer side of the lower end has a structure that is fixedly connected to the inner rod lower slider 20 through threads.

[0050] The output shaft of the outer frame driving motor 10 is connected to the coupling rod 12, and the coupling rod 12 has pin holes on both sides. The coupling rod 12 is connected to the two outer frame driving rods 11 on the left and right sides, and the outer frame driving rod 11 is connected to the outer frame inner ear 7_1 through the shaft hole. When the outer frame driving motor 10 rotates a certain angle, the driving rod drives the side ear to move inward, and the upper part of the clamp outer frame 7 is subjected to an inward pulling force, and the entire clamp outer frame 7 rotates around the shaft sleeve 19 in the side ear, and the clamp outer frame 7 is opened. On the contrary, the clamp outer frame 7 will be closed.

[0051] When the coupling rod 12 is in a horizontal state, the outer frame driving rods 11 on both sides connected thereto are also in a horizontal state, and the entire transmission mechanism is in a fully deployed state. At this time, the two clamp outer frames 7 are in a vertical state, and the hanger is in a completely closed state and cannot be further closed. When the clamp outer frame 7 is closed or opened, the clamp rod 6 will also rotate with the clamp outer frame 7 around the inner rod guide transmission integrated rod 5A and the outer frame transmission rod.

[0052] The inner rod driving motor 16 drives the inner rod guide transmission integrated rod 5A on the left and right sides to rotate through two sets of pulleys 17. Under the action of the transmission screw, the two inner rod middle sliders 13 on the same inner rod guide transmission integrated rod 5A are reversed and will move away from or towards each other according to the forward and reverse rotation of the transmission screw, thereby realizing the separation or movement of the two clamping rods 6, and then the release and clamping of the stacked wheels can be realized.

[0053] Preferred specific examples are:

[0054] The PLC program controls the movement of the mobile truss to drive the spreader to move. The initial state of the spreader is the final state of the last cycle. The clamp outer frame 7 is opened at a certain angle. The clamping rods 6 on the same side are respectively located on both sides of the outer frame rotating rod 4. The coordinate point is the center point of the upper end surface of the truss connection flange 1, and the coordinates are (0, 0, 0);

[0055] After the mobile truss receives the signal to clamp the wheel, the truss controls the spreader to move to the top of the wheel, and the coordinates are (a1, b1, c1) at this time; then the spreader is controlled to move downward to a suitable distance above the stacking platform 8, and the spreader stops falling at this time The coordinates are (a1, b1, c2); the outer frame drive motor 10 is controlled to rotate, and its motor shaft is connected to the coupling rod 12, and the coupling rod 12 is connected to the outer frame drive rods 11 on the left and right sides through the fixing pin 15 and the bayonet 14, and the outer frame drive rod 11 is connected to the outer frame ear 7_1 through the shaft hole. When the coupling rod 12 rotates to a horizontal state, the outer frame drive rods 11 on both sides connected to it are also in a horizontal state, and the entire first transmission mechanism is in a fully deployed state, and at the same time, the clamp outer frame 7 will rotate around the shaft sleeve 19 in the side ear 7_2 of the outer frame at a certain angle until it is in a vertical state, which is a completely closed state and cannot be further closed. At this time, the outer frame lower support 7_3 is completely embedded in the middle groove of the stacking platform 8 and the upper surface of the outer frame lower support 7_3 and the upper surface of the stacking platform 8 are horizontally overlapped, and the lower surface of the wheel is in contact with the upper surface of the outer frame lower support 7_3. Here, the upper part of the clamping rod 6 is fixedly connected to the inner rod upper slider 9, and the inner rod upper slider 9 can rotate around the outer frame transmission rod, and the lower part is fixedly connected to the inner rod lower slider 20, and the inner rod lower slider 20 is connected to the inner rod guide rod 5B. When the outer frame is closed or opened, the clamping rod 6 will rotate around the outer frame transmission rod under the action of the lower end force, that is, it moves with the clamp outer frame 7;

[0056] Then the inner rod driving motor 16 is controlled to rotate, and through the movement of the same group of pulleys 17 and belts 18 responsible for the movement on both sides, the inner rod guide transmission integrated rod 5A also rotates, driving the inner screw structure to rotate, and the inner rod middle slider 13 on the same side of the rod is installed in the opposite direction, and will move away or towards each other according to the forward and reverse rotation of the transmission screw. At this time, the inner rod middle slider 13 on the same side of the clamp is moved towards each other, and the two clamping rods 6 fixed thereto will also move towards each other until the four clamping rods 6 contact the clamped wheel at the same time;

[0057] Then the moving truss starts to move upward, driving the clamp body 3 to move upward, and the outer frame lower support 7_3 lifts up several wheels on the stacking platform 8, exerting axial clamping force to prevent the wheels from falling. At the same time, the inner rod protects the stacked wheels, and even if they are disturbed by external factors such as bumps during the lifting process, they will remain in a stable stacking state without tilting or overturning. The moving truss continues to move upward to lift all the wheels, and the coordinates return to (a1, b1, c1);

[0058] The mobile truss drives the hanger to move, and after carrying the wheel to the specified position (a2, b2, c1), the mobile truss starts to move downward to place the wheel on the specified position (a2, b2, c2), and then controls the hanger to continue to move downward until the workbench of the next process supports the wheel and then stops moving downward (a2, b2, c3). At this time, first control the inner rod drive motor 16 to rotate so that the two clamping rods 6 on the same side of the hanger move away from each other, and then control the outer frame drive motor 10 to rotate so that the clamp outer frame 7 opens a certain angle, and the outer frame lower support 7_3 is separated from the wheel to ensure that the outer frame lower support 7_3 does not interfere with the wheel when the clamp is lifted. The mobile truss starts to move upward to (a2, b2, c1), and then drives the hanger back to the origin coordinate position (0, 0, 0) to perform the next cycle.

[0059] In a second aspect, an embodiment of the present invention further provides a wheel transfer method, which uses an adaptive stacking wheel transfer sling and includes the steps of:

[0060] S1, after the adaptive stacking wheel transfer sling moves to the specified position, the two outer frame components rotate until the outer frame lower support 7_3 contacts the lower surface of the wheel;

[0061] S2, the clamping mechanisms on the two outer frame assemblies cooperate to clamp the stacked wheels;

[0062] S3, the adaptive stacked wheel transport sling moves upward, the outer frame lower support 7_3 lifts the stacked wheels on the stacking platform 8, and transports the stacked wheels to the designated location;

[0063] S4. The adaptive stacked wheel transfer sling is separated from the stacked wheels.

[0064] In the above step S1, the mobile truss controls the sling to move to just above the wheel, controls the sling to move downward to a suitable distance above the stacking platform 8, stops falling, and controls the outer frame drive motor 10 to rotate, that is, the two clamp outer frames 7 rotate inward around the inner rod guide transmission integrated rod 5A to close, ensuring that the outer frame lower support 7_3 is completely embedded in the middle groove of the stacking platform 8 and the upper surface of the outer frame lower support 7_3 and the upper surface of the stacking platform 8 are horizontally overlapped, the lower surface of the wheel is in contact with the upper surface of the outer frame lower support 7_3, and at this time the coupling rod 12 turns to horizontal, and the clamp outer frame 7 also reaches a fully closed state.

[0065] In the above step S2, the inner rod driving motor 16 is controlled to rotate, so that the two clamping rods 6 on the same side of the sling move toward each other until the four clamping rods 6 contact the clamped wheel at the same time.

[0066] In the above step S3, the mobile truss starts to move upward, driving the clamp body 3 to move upward, and the outer frame lower support 7_3 lifts the stacked wheels on the stacking platform 8, exerting axial clamping force to prevent the wheels from falling. At the same time, clamping rods 6 are distributed on the opposite sides of the stacked wheels. The clamping rods 6 protect the stacked wheels from being skewed or overturned even if they are disturbed by external factors such as bumps during the lifting process. The mobile truss continues to move upward to lift the stack and transport the wheels to the designated position.

[0067] In the above step S4, the mobile truss starts to move downward to put the wheel in the specified position, and then controls the sling to continue to move downward until the workbench of the next process supports the wheel and then stops moving downward. At this time, first control the inner rod drive motor 16 to rotate so that the two clamping rods 6 on the same side of the sling move away from each other, and the clamping rods 6 are separated from the wheel. Then control the outer frame drive motor 10 to rotate so that the clamp outer frame 7 opens a certain angle to ensure that the outer frame lower support 7_3 does not interfere with the wheel when the sling is lifted. The mobile truss starts to move upward and drives the sling to move, and then performs the next cycle.

[0068] The self-adaptive stacking wheel transfer sling and wheel transfer method of the present invention have the following advantages:

[0069] 1. It can clamp the stacked high-speed railway wheels. The clamps can adapt to the size of the stacked wheels to prevent the stacked wheels from overturning due to external influences during the transfer process.

[0070] 2. The stacked wheels are clamped by a clamping method. The lifting device is subjected to small torque and has high stability. It is not easy to cause bumps and scratches on the surface of the high-speed rail wheels. Compared with the traditional clamping method for handling single wheels, it improves production efficiency;

[0071] 3. The clamping rod 6 is designed to adapt to the wheel size of the stacked wheels, which can actively adapt to the lifting of heavy-loaded wheels of different sizes. There is no need to change the lifting equipment according to the wheel size, which is universal.

[0072] 4. The clamping rod 6 that is self-adaptive to the size of the stacked wheels can prevent the stacked wheels from being skewed or overturned due to external interference such as collision during the lifting process, and the stacked wheels have good stability and high reliability during the lifting process.

[0073] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
