Description

A special lifting tool for copper ingot annealing Technical Field

[0001] This utility model relates to the field of metal processing auxiliary equipment technology, specifically a special lifting tool for copper ingot annealing. Background Technology

[0002] In the metalworking industry, copper ingot annealing is a crucial process. During annealing, the copper ingot needs to be moved from one location to the annealing furnace. Traditional methods often involve directly binding the ingot with simple hooks or ropes, which presents several problems. Firstly, due to the varying shapes and sizes of copper ingots, traditional lifting tools struggle to grip them accurately, easily causing the ingot to sway and shift during transport, affecting efficiency and potentially creating safety hazards. Secondly, direct contact with the ingot can scratch its surface, impacting its quality. Furthermore, in the high-temperature annealing environment, ordinary lifting tools may release harmful volatile substances due to their material properties, contaminating the copper ingot.

[0003] Therefore, we propose a special lifting tool for copper ingot annealing to solve the above problems. Summary of the Invention

[0004] In view of the problems existing in the prior art, this utility model discloses a special lifting tool for copper ingot annealing. The technical solution adopted includes a basic frame and a gripping component. The basic frame is assembled and welded from four sets of frame rods. The upper surface of the frame rods is provided with a slot. The side wall of the frame rods is provided with a clamping rod that engages with the slot. The interior of the basic frame is provided with a connecting block. The outer side wall of the connecting block is provided with a blind hole. A lifting lug is slidably installed inside the through hole of the side wall of the frame rod, and the other end of the lifting lug is inserted into the blind hole of the outer side wall of the connecting block. The lower surface of the frame rods is symmetrically provided with an adjustment component. The middle of the lower surface of the frame rods is provided with a mounting block. The gripping component is respectively located on the lower surface of the mounting block and below the adjustment component.

[0005] As a preferred embodiment of this utility model, the control component includes a side fixing block, an adjustment groove, a side slider, and a threaded rod. The side fixing block is disposed at the lower end of the frame rod. A threaded adjustment hole is provided through one of the outer side walls of the side fixing block, and another threaded adjustment hole is provided through the adjacent outer side wall at a staggered angle. The adjustment groove is located on the lower surface of the frame rod and is positioned between the side fixing block and the mounting block. The side slider is slidably mounted inside the adjustment groove. One end of the threaded rod is rotatably connected to the side wall of the side slider, and the other end of the threaded rod extends through the threaded adjustment hole and outwards to the outside of the side fixing block. The lower surface of the side slider is fixedly connected to the gripping component.

[0006] As a preferred technical solution of this utility model, the gripping component includes a threaded sleeve and an adjustable clamping arm. The threaded sleeve is fixedly installed on the lower surface of the mounting block and the lower surface of the side slider, respectively. The adjustable clamping arm is an L-shaped rod. The vertical end of the adjustable clamping arm is inserted into the inside of the threaded sleeve by a threaded insertion. The horizontal end of the adjustable clamping arm is provided with an arc-shaped chamfer.

[0007] As a preferred embodiment of this utility model, the inner end of the outer side wall of the adjustable clamping arm is covered with a flexible rubber pad for protection.

[0008] As a preferred embodiment of this utility model, a positioning block is provided in the middle of the lower surface of the connecting block, and the lower end of the positioning post is a semi-circular protrusion.

[0009] The beneficial effects of this utility model are:

[0010] 1. Precise gripping and positioning: The lifting device of this utility model has an adjustable gripping component on the basic frame.

At the same time, the positioning block below the connecting block, with the lower end of the positioning column set as a semi-circular protrusion, can be accurately inserted into the reserved hole in the center of the copper disc. This effectively prevents the copper disc from shifting in the early stage of lifting, achieves rapid positioning, and improves the stability and accuracy of lifting.

[0011] 2. Flexible adjustment to adapt to multiple sizes: The design of the control components allows for flexible adjustment of the spacing between the gripping components. By rotating the threaded rod, the side slider slides in the adjustment groove, thereby changing the position of the gripping components. By using frame rods of different sizes for combination welding, it can meet the gripping needs of copper ingots of different sizes, improving the versatility and applicability of the lifting device.

[0012] 3. Protecting the surface of the copper ingot: The flexible rubber pad attached to the inner end of the outer wall of the adjustable clamping arm plays an important role. When clamping the copper ingot, it can buffer the impact force and prevent the surface of the copper ingot from being scratched, ensuring that the appearance quality of the copper ingot is not affected. At the same time, the rubber pad has stable performance in the high temperature annealing environment and will not produce harmful volatile substances to contaminate the copper ingot, thus ensuring the quality of the copper ingot.

[0013] 4. Stable structure and easy operation: The basic frame is welded together from four sets of frame rods and is connected to the clamp rods through slots, which enhances the stability of the overall structure. During operation, the gripping component can be adjusted and the copper disc can be gripped simply by rotating the threaded rod and the adjustable clamping arm. The operation is simple and quick, which improves work efficiency, reduces the labor intensity of operators, and is suitable for cyclical operation. Attached Figure Description

The locking points of the slots 2 and locking rods 3 are welded and fixed. During operation, according to the actual size of the copper disc, the threaded rotating rod 10 is rotated, causing it to move within the threaded adjustment hole 9 on the side wall of the side fixing block 6. This, in turn, drives the side slider 8 connected to it to slide within the adjustment groove 7, thereby adjusting the position of the gripping component 16. After adjusting the spacing between adjacent gripping components 16, the crane hook hooks onto the lifting lug 5 and slowly lowers the lifting device above the copper ingot stack.
