[0025] In the following description, numerous details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the embodiments of the present invention may be practiced without these specific details. In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring the embodiments of the present invention.

[0026] Please combine Figure 1 As shown, the present invention provides a movable guard plate device for a steel coil clamp.

[0027] In an exemplary embodiment of the present application, the steel coil clamp movable guard plate device includes:

[0028] boom 1;

[0029] The movable guard plate trolley 2 is slidably arranged on the boom 1, and the movable guard plate trolley 2 contacts the side of the steel coil to isolate the boom 1 and the steel coil.

[0030] In this embodiment, the movable guard plate trolley 2 is slidably provided on the boom 1 so that the movable guard plate trolley 2 is in direct contact with the side of the steel coil, thereby achieving isolation between the boom 1 and the steel coil. The isolation structure proposed in this application fundamentally avoids direct contact between the boom 1 and the side of the steel coil, eliminates the possibility of frictional displacement between the two, thereby effectively avoiding the problem of damage to the steel coil caused by the boom 1, reducing the scrapping or re-judgment due to damage to the steel coil, reducing the economic losses of the enterprise, and at the same time helping to improve the yield rate of the steel coil. In addition, the structural design of the movable guard plate trolley 2 slidingly provided on the boom 1 can adapt to the position change of the steel coil during the lifting process, ensuring that the boom 1 and the steel coil are always kept in isolation during the lifting process, and ensuring the continuity and reliability of the protection of the steel coil.

[0031] In an exemplary embodiment of the present application, a guide groove 101 is provided on the boom 1, and a steel wheel is provided on the movable guard trolley 2. The steel wheel is installed in the guide groove 101. The guide groove 101 is used to guide the movement of the steel wheel to position and control the movement direction and distance of the movable guard trolley 2.

[0032] In this embodiment, when the spreader clamps a steel coil, the movable guard trolley 2 is subjected to thrust due to contact with the side of the steel coil. At this time, the steel wheels on the movable guard trolley 2 move along the guide slot 101 on the boom 1. The guide slot 101 limits the steel wheels' movement trajectory, thereby precisely controlling the movement of the movable guard trolley 2, allowing it to move only along the direction of the guide slot 101. This prevents the movable guard trolley 2 from shifting, shaking, or deviating from its preset trajectory when subjected to force. Furthermore, the length and structural design of the guide slot 101 limit the range of movement of the steel wheels, thereby controlling the movement distance of the movable guard trolley 2. This ensures that the movable guard trolley 2 can adapt to changes in the position of the steel coil when in contact with it, while not moving out of its effective protection range due to excessive movement. Through the directional and fixed-distance movement of the steel wheels within the guide slot 101, the movable guard trolley 2 can maintain stable contact with the side of the steel coil, continuously isolating the boom 1 from the steel coil, effectively protecting the steel coil while ensuring the stability and reliability of the spreader operation.

[0033] In an exemplary embodiment of the present application, the guide groove 101 extends along the length direction of the boom 1 .

[0034] In this embodiment, during the process of clamping and lifting the steel coil with the sling, the force exerted by the steel coil on the movable guard plate trolley 2 is mainly generated along the length direction of the boom 1; since the guide groove 101 extends along the length direction of the boom 1, the moving direction of the steel wheel in the guide groove 101 is consistent with the direction of the force, so that the movable guard plate trolley 2 can be smoothly displaced and adjusted along the length direction of the boom 1.

[0035] In an exemplary embodiment of the present application, a spring 3 is further included, which is connected to the movable guard plate trolley 2 and is used to drive the movable guard plate trolley 2 to reset.

[0036] In this embodiment, when the sling clamps the steel coil, the movable guard trolley 2 is subjected to the lateral thrust of the steel coil and will move along the guide groove 101 on the boom 1. At this time, the spring 3 connected to the movable guard trolley 2 will be stretched or compressed due to the displacement of the trolley, storing elastic potential energy. When the steel coil is released, the movable guard trolley 2 is reset under the elastic force of the spring 3 and returns to its initial height position.

[0037] In an exemplary embodiment of the present application, one end of the spring 3 is fixedly connected to the movable guard trolley 2 , and the other end is fixedly connected to the boom 1 .

[0038] In this embodiment, the dynamic adaptation and automatic reset of the movable guard plate trolley 2 are achieved through the elastic deformation and reset characteristics of the spring 3.

[0039] In an exemplary embodiment of the present application, a screw rod 4 is threadedly connected to the boom 1 , and the spring 3 is fixedly connected to the screw rod 4 and the movable guard plate trolley 2 respectively. The screw rod 4 is used to adjust the height position of the movable guard plate trolley 2 .

[0040] In this embodiment, when the height of the movable guard trolley 2 needs to be adjusted, the screw rod 4 is rotated, and the threaded engagement between the screw rod 4 and the boom 1 changes the extension length of the screw rod 4 relative to the boom 1. Since one end of the spring 3 is fixedly connected to the screw rod 4 and the other end is fixedly connected to the movable guard trolley 2, the height of the spring 3, and thus the height of the movable guard trolley 2, can be adjusted by adjusting the depth of the threaded connection between the screw rod 4 and the boom 1 to accommodate different steel coil hoisting operations.

[0041] In an exemplary embodiment of the present application, the screw rod 4 is arranged along the axial direction of the spring 3, and the height of the movable guard trolley 2 is adjusted by rotating the screw rod 4 and adjusting the depth of the threaded connection with the boom 1.

[0042] In this embodiment, since the screw rod 4 is arranged along the axial direction of the spring 3, and the spring 3 is fixedly connected to the screw rod 4 and the movable guard trolley 2 respectively, when the screw rod 4 is rotated, the threaded fit between the screw rod 4 and the boom 1 will cause the screw rod 4 to move along its own axial direction, thereby changing the extension or retraction length of the screw rod 4 relative to the boom 1, and then adjusting the height of the movable guard trolley 2.

[0043] In an exemplary embodiment of the present application, a wear-resistant layer is provided on the side of the movable guard trolley 2 facing the side of the steel coil, and the wear-resistant layer is used to reduce the wear when the movable guard trolley 2 contacts the side of the steel coil.

[0044] In this embodiment, during the process of lifting the steel coil with the hoist, the movable guard trolley 2 needs to maintain contact with the side of the steel coil to isolate the lifting arm 1 and the steel coil. At this time, relative friction may occur between the two due to slight shaking or position adjustment of the steel coil; the wear-resistant layer is made of a material with high hardness and wear resistance, and its surface friction resistance is much higher than that of the movable guard trolley 2 body and the side of the steel coil; when the movable guard trolley 2 rubs against the side of the steel coil, the wear-resistant layer will act as a direct contact medium and bear the main friction effect, reducing the loss of the movable guard trolley 2 body and extending its service life; at the same time, it avoids the secondary damage to the side of the steel coil caused by debris or rough surface generated by its own wear, further ensuring the integrity of the steel coil, reducing the risk of scrapping or re-judgment of the steel coil due to friction, and enhancing the protection effect of the steel coil.

[0045] In an exemplary embodiment of the present application, the shape of the movable guard trolley 2 is adapted to the curvature of the side surface of the steel coil.

[0046] In this embodiment, the side of the steel coil usually has an arc-shaped structure. When the shape of the movable guard trolley 2 is adapted to the arc, during the lifting process, the movable guard trolley 2 can form a large area and close contact with the side of the steel coil, which can disperse the pressure of the contact point and avoid indentation or deformation on the side of the steel coil due to excessive local pressure.

[0047] In an exemplary embodiment of the present application, the outer circumference of the steel wheel is provided with anti-skid patterns to enhance the friction between the steel wheel and the guide groove 101 .

[0048] In this embodiment, when the sling clamps and lifts the steel coil, the movable guard trolley 2 will move along the guide groove 101 as the position of the steel coil changes, and the contact surface between the steel wheel and the guide groove 101 will generate a relative force; by providing anti-slip grooves on the outer peripheral surface of the steel wheel, the roughness of the contact surface between the two can be effectively increased.

[0049] Working principle: By slidingly setting a movable guard trolley 2 on the boom 1, the movable guard trolley 2 is in direct contact with the side of the steel coil, thereby achieving isolation between the boom 1 and the steel coil. The isolation structure proposed in this application fundamentally avoids direct contact between the boom 1 and the side of the steel coil, eliminates the possibility of friction displacement between the two, and effectively avoids the problem of damage to the steel coil caused by the boom 1, reduces the scrapping or re-judgment due to damage to the steel coil, reduces the economic losses of the enterprise, and is conducive to improving the yield rate of the steel coil. In addition, the structural design of the movable guard trolley 2 slidingly set on the boom 1 can adapt to the position change of the steel coil during the lifting process, ensures that the boom 1 and the steel coil are always kept in isolation during the lifting process, and ensures the continuity and reliability of the protection of the steel coil.

[0050] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
