Technical Field
[0001] This utility model relates to the technical field of winding aid arm clamping device, and in particular to a winding aid arm clamping device based on three-position hydraulic cylinder control. Background Technology
[0002] During the coiling process, the strip first enters the coiler and is bitten and wound onto the coiler drum by the belt on the coiler. After tension is formed, the coiler exits and the strip is coiled under tension.

[0004] However, the existing adjustment method requires operators to climb to the top of the winding machine to insert the safety pin of the swing frame of the winding aid, then remove and install the positioning bolt, and pry the arm to the required position before inserting and locking the positioning bolt. After that, they have to climb to the top again to pull out the safety pin. This process poses safety hazards such as falls from heights and mechanical injuries. The positioning hole is larger than the positioning bolt, and after long-term use, the positioning hole will wear down, resulting in a large deviation in positioning accuracy, which will affect the winding aid effect.

Detailed Implementation
[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figures 1-5 This utility model provides a technical solution: a winding aid arm clamping device based on three-position hydraulic cylinder control, including an arm clamping support frame 1, an arm clamping connecting frame 2 fixedly connected to one end of the arm clamping support frame 1, a first rotating shaft 3 provided at the bottom end of the arm clamping connecting frame 2, one end of the first rotating shaft 3 extending through the arm clamping support frame 1 to one side of the arm clamping support frame 1, a first hydraulic cylinder 7 fixedly connected below the first rotating shaft 3 on the outer side of the arm clamping support frame 1, a second hydraulic rod 8 provided at the output end of the front end of the first hydraulic cylinder 7, one end of the second hydraulic rod 8 extending to the bottom end of the first rotating shaft 3. A connecting seat 14 is fixedly connected to the top of the boom connecting frame 2. A first hydraulic rod 5 is fixedly connected to the top of the connecting seat 14. A second rotating shaft 4 is provided on both sides of the connecting seat 14. The two sides of the second rotating shaft 4 extend to the outside of the boom connecting frame 2. A second hydraulic cylinder 11 is fixedly connected to the outer side of the boom connecting frame 2. A third hydraulic rod 12 is provided at the output end of one end of the second hydraulic cylinder 11. One end of the third hydraulic rod 12 extends to the outside of the second rotating shaft 4. Two mounting slots are provided at the bottom of the boom support frame 1, so as to facilitate the connection of the boom support frame 1 to other equipment through the mounting slots.
[0024] Please see Figures 2-3In this embodiment, the arm support frame 2 and the first rotating shaft 3 are an integral structure. One end of the first rotating shaft 3 is provided with a rotating hole on the inner side of the arm support frame 1. The other end of the first rotating shaft 3 extends through the rotating hole to the outer side of the arm support frame 1. The top of the second hydraulic rod 8 opposite to the first rotating shaft 3 is provided with a rack 9. The top of the rack 9 is provided with a first transmission gear 10 on the outer side of the first rotating shaft 3. The rack 9 and the first transmission gear 10 mesh with each other, and the first transmission gear 10 is rotated by the first oil cylinder 7 in conjunction with the second hydraulic rod 8. The first transmission gear 10 and the arm support frame 2 are an integral structure, which facilitates the adjustment of the angle of the arm support frame 2.
[0025] Please see Figures 4-5 The bottom end of the first hydraulic rod 5 is located at the output end of the second rotating shaft rod 4. The connecting seat 14 and the second rotating shaft rod 4 are integrally formed. One end of the second rotating shaft rod 4 is located on the inner side of the arm connecting frame 2 and has a rotating hole. The other end of the second rotating shaft rod 4 extends through the rotating hole to the outer side of the arm connecting frame 2. The top of the third hydraulic rod 12 opposite to the second rotating shaft rod 4 is provided with a rack 9. Above the rack 9, on the outer side of the second rotating shaft rod 4, is a second transmission gear 13. The rack 9 and the second transmission gear 13 mesh with each other, thereby causing the second transmission gear 13 to rotate through the second cylinder 11 in conjunction with the third hydraulic rod 12. The second transmission gear 13 and the connecting seat 14 are integrally formed, which facilitates the adjustment of the angle of the connecting seat 14.
[0026] During operation, the boom support frame 1 is connected to the equipment, the power is turned on, and the device is started. When the angle of the device needs to be adjusted, the first hydraulic cylinder 7 is used in conjunction with the second hydraulic rod 8 to extend and retract. The rack 9 on the outer side of the second hydraulic rod 8 meshes with the first transmission gear 10. During the extension and retraction of the second hydraulic rod 8, the second hydraulic rod 8 causes the first transmission gear 10 to rotate. The first transmission gear 10 and the boom connecting frame 2 are an integral structure, which facilitates the adjustment of the angle of the boom connecting frame 2. The second hydraulic cylinder 11 is used in conjunction with the third hydraulic rod 12 to extend and retract. The rack 9 on the outer side of the third hydraulic rod 12 meshes with the second transmission gear 13. During the extension and retraction of the third hydraulic rod 12, the third hydraulic rod 12 causes the second transmission gear 13 to rotate. The second transmission gear 13 and the connecting seat 14 are an integral structure, which facilitates the adjustment of the angle of the connecting seat 14.
[0027] Through the above steps, the first hydraulic cylinder 7, in conjunction with the second hydraulic rod 8, causes the first transmission gear 10 to rotate, thereby facilitating the adjustment of the angle of the arm connecting frame 2 via the second hydraulic rod 8. The second hydraulic cylinder 11, in conjunction with the third hydraulic rod 12, causes the second transmission gear 13 to rotate, thereby facilitating the adjustment of the angle of the connecting seat 14 via the third hydraulic rod 12. This solves the problem that the existing adjustment method requires the operator to climb to the top of the winding machine to insert the safety pin of the winding aid swing frame, then remove and install the positioning bolt, and then pry the arm to the required position before inserting and locking the positioning bolt. After completion, the operator must climb to the top again to remove the safety pin. This process also poses safety hazards such as falls from height and mechanical injuries. Furthermore, the positioning hole is larger than the positioning bolt, and after long-term use, the positioning hole wears down, leading to a large deviation in positioning accuracy, which affects the winding aid effect.
