[0030] Specifically, a protective mechanism 4 is provided on the top of the loading platform 1, and the protective mechanism 4 includes a support column 401, a protective plate 402 and an anti-collision pad 403. The support column 401 is fixedly installed around the top of the loading platform 1, and the support column 401 is fixedly connected to the support plate 8. The protective plate 402 is fixedly installed at the left and right ends of the inner side of the support column 401, and the anti-collision pad 403 is fixedly installed on the inner surface of the protective plate 402.

[0031] Furthermore: the support column 401 provides support and fixing points for the protective plate 402. The support column 401 is also fixedly connected to the support plate 8 to ensure a firm connection between the protective mechanism 4 and the support plate 8, thereby enhancing the structural stability of the entire transfer mechanism. The main function of the protective plate 402 is to prevent the plastic-coated steel wire from being damaged due to accidental collision or external force during transportation, and also to protect the operator from injury.

[0035] Further: the movable shaft 601 allows the loading platform 1 to rotate or tilt within a certain range to facilitate adjustment of the direction and position of the transfer mechanism. The fixed frame 602 ensures that the movable casters 604 maintain the correct position and direction during the movement. The function of the fixed shaft 603 is to ensure that the movable casters 604 can rotate freely on the horizontal plane, thereby realizing the flexible movement of the transfer mechanism. The movable casters 604 are key components of the mobile mechanism 6. They allow the transfer mechanism to move easily on the ground, providing good maneuverability whether it is straight propulsion or turning.

[0036] Specifically, an automatic wrapping mechanism 7 is provided at the bottom of the loading platform 1 and the bottom of the inner cavity. The automatic wrapping mechanism 7 includes a driving motor 701, a support frame 702, a controller 703, a driving shaft 704, a hook 705, a limit plate 706 and a wire feeding hole 707. The driving motor 701 is fixedly installed at the bottom of the loading platform 1, and the support frame 702 is fixedly installed at the bottom of the driving motor 701 and is fixedly connected to the loading platform 1.

[0037] Furthermore: the drive motor 701 serves as the power source of the automatic wrapping mechanism 7. The drive motor 701 converts electrical energy into mechanical energy to drive the drive shaft 704 to rotate, thereby realizing automatic winding of the plastic-coated steel wire and being fixedly connected to the loading platform 1 to provide stable support for the drive motor 701 and ensure its stability during operation.

[0038] Specifically, the controller 703 is fixedly mounted on the bottom of the front side of the support plate 8, the drive shaft 704 is rigidly connected to the input end of the drive motor 701 and is movably connected to the loading platform 1, the hook 705 is fixedly mounted on the surface of the drive shaft 704, the limit plate 706 is fixedly mounted on the top of the inner cavity of the loading platform 1 and is movably connected to the drive shaft 704, and the steel wire feeding circular hole 707 is opened on the back side of the support plate 8.

[0039] Furthermore: the controller 703 is used to control the start and stop, speed and direction and other parameters of the drive motor 701 to achieve precise control of the automatic wrapping process. The function of the drive shaft 704 is to transmit the rotational motion of the drive motor 701 to the hook 705, so that the hook 705 can rotate around the drive shaft 704 to complete the winding of the plastic-coated steel wire. The hook 705 is used to fix one end of the plastic-coated steel wire. As the drive shaft 704 rotates, the hook 705 drives the plastic-coated steel wire to be wound. The function of the limit plate 706 is to limit the winding range of the plastic-coated steel wire to prevent the steel wire from being wound too tightly or too loosely, ensuring the uniformity and stability of the winding. The steel wire feeding hole 707 ensures that the plastic-coated steel wire can smoothly enter the automatic wrapping mechanism 7 to start the winding process.

[0040] Working principle:

[0041] When in use, ensure that all parts of the plastic-coated steel wire transfer mechanism are intact, introduce the plastic-coated steel wire into the loading platform 1 through the steel wire feeding circular hole 707 and fix it to the hook 705, start the driving motor 701 through the controller 703, and generate a driving torque through the driving motor 701 to drive the driving shaft 704 to rotate, and drive the hook 705 and the plastic-coated steel wire to rotate through the driving shaft 704. As the driving shaft 704 rotates, the hook 705 drives the plastic-coated steel wire to be wound, and the winding range of the plastic-coated steel wire is limited by the limit plate 706 to prevent the steel wire from being wound too tightly or too loosely, and start the electric lifting rod 204 to achieve lifting through electric control, thereby driving the slider 203 The plastic-coated steel wire fixing plate 302 moves downward to effectively fix the wrapped plastic-coated steel wire to prevent it from moving or falling off during transportation. The soft sponge 303 protects the surface of the plastic-coated steel wire to avoid damage during the fixing process. The operator can move the entire transportation mechanism by pushing the pushing rod 501. The anti-slip pad 502 increases the friction between the operator's hand and the pushing rod 501 to prevent the hand from sliding during the pushing process. The loading platform 1 is moved to the desired position by moving the casters 604, thereby realizing the positioning or transportation of the plastic-coated steel wire, ensuring that during the movement, the protective plate 402 and the anti-collision pad 403 in the protective mechanism 4 can protect the plastic-coated steel wire from damage.

[0042] To sum up: the connecting plate 201, slide rail 202, slider 203 and electric lifting rod 204 contained in the adjusting mechanism 2 can enable the equipment to have the function of accurately adjusting the upper and lower positions of the plastic-coated steel wire fixing plate 302 as needed during use, so as to adapt to the fixing requirements of plastic-coated steel wires of different heights and specifications, thereby improving the adaptability and convenience of operation of the equipment and ensuring the stability and accuracy of the winding process. The support column 401, protective plate 402 and anti-collision pad 403 contained in the protective mechanism 4 can enable the equipment to have the function of preventing the plastic-coated steel wire from being damaged due to accidental collision or external force during transportation during use. At the same time, the protective plate 402 also protects the operator from injury. The anti-collision pad 403 provides buffering when the plastic-coated steel wire contacts the protective plate 402, reduces the impact force, thereby further protecting the plastic-coated steel wire from damage, reducing the risk of damage to the plastic-coated steel wire, and also improving the safety of the operator and ensuring the structural stability of the equipment.
