[0033] Example 1
[0034] Reference Figures 1-2 This is the first embodiment of the present invention, which provides an auxiliary adjustment mechanism.
[0035] The width adjustment component 1 is used to adjust the adaptability width of the winding device to accommodate drums of different sizes. The track screw 11 rotates on the stable platform 21, and the drive component 12 is helically engaged with the outer wall of the track screw 11. The drive component 12 and the track screw 11 can be implemented using a ball screw. The drive component 12 performs translational motion during its movement in conjunction with the track screw 11.
[0036] Extension rods 13 are rotatably mounted on both sides of the drive member 12. The extension rods 13 can follow the movement of the drive member 12 and act as connecting rods. When the drive member 12 moves along the track screw 11, it can cause the extension rods 13 and the mating mechanism fixed at the other end of the extension rods 13 to push or pull. When the extension rods 13 push, the width adjustment component 1 achieves width extension. When the extension rods 13 pull, the width adjustment component 1 achieves width narrowing. The width adjustment component 1 can adjust the width according to the wire rope reels of different widths to ensure adaptability.
[0037] The clamping assembly 2 is used to clamp the wire rope reel onto the device, preventing safety hazards caused by loosening. Downward pressure output ends 22 are installed on both sides of the stable platform 21. These downward pressure output ends 22 can be driven by a motor for vertical lifting and lowering. A pressure assembly 23 is installed and connected to the top of the downward pressure output ends 22. The pressure assembly 23 has a central opening for inserting a sturdy metal tube.
[0038] When the pressure assembly 23 descends under the control of the downward pressure output end 22, the corresponding metal pipe also descends, acting on the central ring of the wire rope reel to tighten the wire rope reel.
[0039] Example 2
[0040] Reference Figures 1-5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that a corresponding adjustment cavity 211 is fixedly opened inside the stable frame 21. The adjustment cavity 211 is used to accommodate the corresponding track screw 11. In this solution, there can be two track screws 11. The contact ends of the two track screws 11 adopt a concave-convex design to achieve interlocking. The non-contact end of one track screw 11 is rotatably connected to the inner wall of the adjustment cavity 211, and the non-contact end of the other track screw 11 passes through the adjustment cavity 211 and is located outside the adjustment cavity 211.
[0041] The track screw 11 on the outside of the adjusting cavity 211 is connected to a coupling 14. A width adjustment output end 15 is connected and installed on the other side of the coupling 14. The width adjustment output end 15 can provide corresponding driving force for the motor.
[0042] After the width adjustment output terminal 15 starts working, it can control the coordinated movement of the drive component 12 and the track screw 11, so that the drive component 12 performs corresponding translational movements, and the two track screws 11 correspond to the two drive components 12.
[0043] Extension rods 13 are respectively provided on both sides of the drive member 12. The ends of the extension rods 13 are rotatably connected to the support member 16. When the drive member 12 moves along the track screw 11, the extension rods 13 can push or pull the support member 16. The outer wall of the support member 16 is fixedly connected to the wheel set platform 161 and the mating platform 162. The width adjustment component 1 can ultimately achieve synchronous opening and closing of the wheel set platform 161 and the mating platform 162 by means of the power driven by the width adjustment output end 15, thereby realizing width adjustment.
[0044] A housing 221 is fixedly installed on the outside of the pressure output end 22. The housing 221 can be fixedly connected to the side wall of the stable platform 21. The pressure output end 22 itself can be driven by a motor to move vertically. The housing 221 serves to accommodate and protect the output end.
[0045] An observation slot 231 is fixedly provided in the center of the pressure assembly 23. A stabilizing block 2311 is slidably provided on the inner wall of the observation slot 231. A through hole 2312 is fixedly provided in the center of the stabilizing block 2311. A sturdy metal tube can be passed through the through hole 2312. An elastic element 232 is fixedly provided on the top of the stabilizing block 2311. The other end of the elastic element 232 is fixedly connected to the inner wall of the observation slot 231.
[0046] When the pressure output end 22 starts working, the metal tube contacts the inner ring of the wire rope reel, pushing against it. Under the reaction force, the metal tube will cause the stabilizing block 2311 to move in the opposite direction to a moderate degree, thereby squeezing the elastic element 232. The operator only needs to observe the state of the elastic element 232 through the observation slot 231 to assess whether the wire rope reel is being stabilized by the metal tube.
[0047] Example 3
[0048] Reference Figures 1-6 This is the third embodiment of the present invention, which adds a winding device based on the above embodiments.
[0049] The winding assembly 3 is used to wind up the wire rope. Two drive wheels 31 are arranged above the wheel assembly platform 161, and two driven wheels 32 are arranged above the platform 162. The drive wheels 31 and driven wheels 32 have the same size and angle, and the driven wheels 32 cooperate with the rotation of the drive wheels 31.
[0050] A rotary output end 33 is fixedly installed on the side wall of the wheel assembly platform 161. The rotary output end 33 can be a corresponding motor. The rotary output end 33 is provided with two corresponding transmission wheels 31. The rotary output end 33 starts synchronously. On the other side of the rotary output end 33, the transmission wheels 31 can start rotating simultaneously through an adaptive transmission such as a gear set.
[0051] The cable routing assembly 4 is used to adjust the adaptability range of the cable routing, accommodating wire rope reels of different widths. A main control cabinet 41 is fixedly installed at the end of the stabilizing platform 21. A corresponding drive motor and reducer are installed on top of the main control cabinet 41 for cable routing. The coupling 14 and the width adjustment output end 15 are both located inside the main control cabinet 41. The top of the main control cabinet 41 is connected to the cable routing output end 42, which is also connected to a support end 43. The support end 43 has a parallelogram structure, consisting of two sets of symmetrical connecting rods. Driven by the drive motor and reducer included in the cable routing output end 42, the swing angle is adjusted. The swing angle of the parallelogram mechanism is adjusted according to the requirements of wire rope reels of different widths, thus adapting to different cable routing working ranges. The bottom of the support end 43 is rotatably connected to the drive motor and the top of the main control cabinet 41, allowing the support end 43 to change angles under the control of the drive motor.
[0052] The outer wall of the support end 43 can be fixedly connected to the angle sensor required for operation, which is used to monitor the swing angle of the parallelogram mechanism in real time and provide feedback signals to the control system. In addition, the calculation roller 432 is fixedly connected to the encoder for measuring the cable length.
[0053] A movable guide wheel 431 is installed inside the guide assembly 44. A calculation roller 432 is installed on one side of the movable guide wheel 431. The movable guide wheel 431 is elastically installed inside the guide assembly 44 by a spring, and the calculation roller 432 is installed on one side. Under the action of the spring, the movable guide wheel 431 presses the cable, ensuring that the cable is in close contact with the calculation roller 432.
