Description

Technical Field

[0001] This utility model relates to a special tool for hoisting and transporting residual rolls, and belongs to the field of hoisting tool technology. Background Technology

[0002] In the production of aluminum coils, a stripping operation is often required. After stripping, the coiled scrap needs to be transferred from the transport line to a designated area. Currently, this is done using forklifts and other auxiliary tools. However, because these tools are not specialized, positioning the scrap on the forklift is difficult, resulting in low handling efficiency and frequent need for multiple handling and adjustments. This process consumes significant manpower and time, leading to low work efficiency. Furthermore, the high temperature of the aluminum coils during production, along with the high temperature of the scrap, poses a significant challenge to operators who repeatedly handle the scrap, increasing the operational difficulty and potentially threatening their safety. Therefore, developing a specialized tool for efficiently and safely lifting and transporting scrap is of significant practical importance. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a special tool for lifting and transporting scrap rolls, including a left lifting tool and a right lifting tool, wherein both the left and right lifting tools are composed of an upper clamping arm, a lower clamping arm, a lifting ring, and a lifting rope;

[0005] All the upper clamping arms are straight arms, and their bottom ends are provided with serrated upper contact surfaces.

[0006] The lower clamping arms are all U-shaped curved arms, with their top ends hinged to the upper clamping arms, and their bottom ends having serrated lower contact surfaces on the side adjacent to the upper contact surface.

[0007] All lifting rings are hinged to the top of the upper clamping arm;

[0008] The bottom ends of the suspension ropes are all connected to the lifting rings, and the top ends are used to suspend them from the crane hooks.

[0009] Preferably, the upper contact surfaces are all arc-shaped surfaces that gradually extend outward from bottom to top, and the convex side of the arc-shaped surfaces all faces downward.

[0010] Preferably, the lower contact surfaces are all inclined surfaces that gradually extend outward from bottom to top.

[0011] Preferably, the top end of the curved arm is fixedly provided with a connecting protrusion, and is hinged to the upper clamping arm through the connecting protrusion.

[0012] Preferably, all the suspension ropes are cables.

[0013] Preferably, the upper clamping arm, lower clamping arm, and lifting ring are all made of stainless steel.

[0014] Compared with the prior art, the present invention has the following advantages: When using this special tool for lifting scrap aluminum strips, the top of the lifting ropes of the left and right lifting devices are suspended by the hook of the crane. The operator clamps the left edge of the non-end (middle section) of the scrap aluminum strip between the upper and lower contact surfaces of the left lifting device, and clamps the right edge of the non-end (middle section) of the scrap aluminum strip between the upper and lower contact surfaces of the right lifting device. When the crane lifts the scrap aluminum strip, the left and right lifting devices clamp the edges of the scrap aluminum strip respectively. The crane can move the scrap aluminum strip to the designated area in one go, which improves work efficiency.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Attached Figure Description
