Description

Technical Field

[0001] This utility model belongs to the field of lifting device tools technology, specifically relating to a lifting tool for solid round non-ferrous metal billets to prevent them from falling off. Background Technology

[0002] Lifting tools are core equipment for efficient material transfer in industrial production. They are widely used in the lifting of various billets and workpieces. In the production and processing of solid round non-ferrous metal billets (such as copper bars, aluminum bars, etc.), automatic round steel lifting tools, with their precise mechanical clamping structure, can stably grasp billets of different diameters, avoid surface damage, and greatly improve lifting efficiency and safety, making them key equipment in the transfer of such billets.

[0003] Currently, existing automatic round steel lifting devices are equipped with rubber anti-slip structures inside to prevent round non-ferrous metals from slipping during use. However, these rubber anti-slip structures wear out over time, leading to a decrease in their anti-slip effectiveness. Therefore, the anti-slip structures need to be replaced regularly. However, it is difficult to detect the early signs of aging and wear of the anti-slip structures. Only when the anti-slip structures are severely aged and the round non-ferrous metals shift significantly during lifting can the problem be discovered, posing a significant safety hazard.

[0004] According to safety regulations, no one should stand under the lifting equipment when hoisting non-ferrous metals. After the equipment is clamped, it moves the round metal upwards. During the operation, the workers have no time to observe whether the hoisting is slipping.

[0005] In summary, existing anti-falling hoisting tools suffer from the problems of inconvenience in observation and time-consuming replacement of anti-slip rubber. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a lifting tool for solid round non-ferrous metal billets that prevents them from falling off, which addresses the shortcomings of the prior art. The tool has a novel and reasonable design, is easy to observe, is highly practical, and is easy to promote and use.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A lifting tool for preventing solid round non-ferrous metal billets from falling off includes an automatic round steel lifting device body, wherein self-inspection mechanisms are provided on both sides of the inner walls of the two grippers of the automatic round steel lifting device body. The self-testing mechanism includes a glass chamber, a force-bearing block, a first short shaft, and a second short shaft. The glass chamber is embedded in the inner wall of the gripper. The first short shaft is located inside the glass chamber. The outer surfaces of the first and second short shafts are rotatably connected to the inner wall of the gripper. A rubber roller is fixedly connected to the outer surfaces of each of the first and second short shafts. A locking block is fixedly connected to one side of the force-bearing block. The outer surface of the locking block is slidably connected to the inside of the second short shaft. When the force-bearing block is pressed downward, the locking block releases its limiting position on the second short shaft. A force-bearing spring is fixedly connected to the lower surface of the force-bearing block to support the force-bearing block's reset. The surface of the first minor axis facing the glass chamber is covered with color to allow observation of its rotation.

[0008] Furthermore, each of the grippers has a mounting bracket fixedly connected to its inner wall, and the inner wall of the mounting bracket has several identical rectangular frames fixedly connected to it.

[0009] Furthermore, the inner wall of each of the rectangular frames is rotatably connected to a long shaft, and the outer surface of each long shaft is rotatably connected to the inner wall of the gripper.

[0010] Furthermore, a rotating plate is fixedly connected to the left end of each of the long shafts for manual rotation.

[0011] Furthermore, a connecting plate is fixedly connected to the outer surface of each of the long shafts, and a rubber pad is fixed to each of the two opposite sides of the outer side of each connecting plate.

[0012] Furthermore, the connecting plate and the rubber pad are secured by two sets of fixing bolts.

[0013] This utility model has the following advantages compared with the prior art: This utility model relates to a lifting tool for preventing the solid round non-ferrous metal billets from slipping. It incorporates a rubber roller. When the equipment clamps the round non-ferrous metal, the rubber roller makes close contact with the outer surface of the metal. Therefore, when the rubber pad ages and can no longer provide sufficient friction, causing the non-ferrous metal to slip, the rubber roller will rotate. This rotation of the rubber roller drives the first short shaft to rotate, with the marking color facing the glass chamber. When the rubber roller is not rotating, the marking color on the surface of the first short shaft can be seen through the glass chamber; conversely, when the rubber roller is rotating, the marking color cannot be seen through the glass chamber. Thus, the operator only needs to periodically check the marking color through the glass chamber. The marking color on the surface of the first short shaft can be observed in the glass chamber. Additionally, when the equipment clamps non-ferrous metal, it squeezes the force block, causing the locking block to move downwards and to the outside of the second short shaft. At this time, the locking block does not limit the second short shaft, so the second short shaft, rubber roller, and first short shaft can rotate freely. Therefore, it can be ensured that the rubber roller only rotates when there is non-ferrous metal. When there is no non-ferrous metal squeezing the force block, the force block and locking block will move upwards under the action of the force spring, and the locking block will re-enter the second short shaft, limiting its movement and preventing the rubber roller from rotating when not sliding on non-ferrous metal.

[0014] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0016] Example of a lifting tool for preventing solid round non-ferrous metal billets from falling off: like Figures 1-5As shown, the anti-falling lifting tool for solid round non-ferrous metal billets includes an automatic round steel lifting device body, and the two grippers 1 of the automatic round steel lifting device body are provided with self-inspection mechanisms 2 on both sides of the inner wall of the two grippers 1. The self-inspection mechanism 2 includes a glass chamber 202, a force-bearing block 203, a first short shaft 204, and a second short shaft 205. The glass chamber 202 is embedded in the inner wall of the gripper 1. The first short shaft 204 is disposed inside the glass chamber 202. The outer surfaces of the first short shaft 204 and the second short shaft 205 are rotatably connected to the inner wall of the gripper 1. A rubber roller 201 is fixedly connected to the outer surfaces of each of the first short shaft 204 and the second short shaft 205. A locking block 206 is fixedly connected to one side of the force-bearing block 203. The outer surface of the locking block 206 is slidably connected to the inside of the second short shaft 205. When the force-bearing block 203 is pressed downward, the locking block 206 releases its limiting position on the second short shaft 205. A force-bearing spring 207 is fixedly connected to the lower surface of the force-bearing block 203 to support the force-bearing block 203 to reset.

[0017] The surface of the first short axis 204 facing the glass chamber 202 is covered with color to facilitate observation of its rotation. In this embodiment, the identification color is set to green, and the other outer surfaces of the first short axis 204 are covered with red for easy observation.

[0018] Each of the aforementioned grippers 1 has a mounting bracket 5 fixedly connected to its inner wall, and the inner wall of the mounting bracket 5 has several identical rectangular frames 4 fixedly connected to it. By providing the mounting bracket 5 and the rectangular frames 4, the mounting bracket 5 can provide a position for fixing the rectangular frames 4.

[0019] Each of the above rectangular frames 4 has a long shaft 8 rotatably connected to its inner wall, and the outer surface of each of the above long shafts 8 is rotatably connected to the inner wall of the gripper 1.

[0020] Each of the aforementioned long shafts 8 is fixedly connected to a rotating plate 9 at its left end for manual rotation. By providing the rotating plate 9, the operator can apply rotational power to the rotating plate 9, causing the connecting plate 7 and the long shaft 8 to rotate.

[0021] Each of the aforementioned long shafts 8 has a connecting plate 7 fixedly connected to its outer surface, and a rubber pad 3 is fixed to each of the two opposite outer surfaces of each connecting plate 7. The rubber pads 3 increase the friction between the equipment and the non-ferrous metal, preventing the non-ferrous metal from slipping. The connecting plate 7 and the rubber pads 3 are fixed by two sets of fixing bolts 6.

[0022] In use, this invention features a rubber roller 201. When the device clamps a round non-ferrous metal, the rubber roller 201 makes close contact with the outer surface of the non-ferrous metal. Therefore, when the rubber pad 3 ages and can no longer provide sufficient friction to the non-ferrous metal, causing it to slip, the rubber roller 201 will rotate. This rotation of the rubber roller 201 drives the first short shaft 204 to rotate. The surface of the first short shaft 204 is covered with red and green, with the green side facing the glass chamber 202. Therefore, when the rubber roller 201 is not rotating, the first short shaft 204 can be seen through the glass chamber 202. The green color on the surface of the first short shaft 204 completely obscures the red color. Conversely, when the rubber roller 201 rotates, the red color can be seen through the glass chamber 202. Therefore, the operator only needs to periodically observe the color of the surface of the first short shaft 204 through the glass chamber 202. Additionally, when the equipment clamps non-ferrous metals, it squeezes the force block 203, causing the clamping block 206 to move downwards, moving it to the outside of the second short shaft 205. At this time, the clamping block 206 does not limit the second short shaft 205, so the second short shaft 205, the rubber roller 201, and the first short shaft 204 are only partially closed at this point. The rubber roller 201 can rotate freely, thus ensuring that it only rotates when there is non-ferrous metal present. When there is no non-ferrous metal pressing against the force block 203, the force block 203 and the locking block 206 will move upward under the action of the force spring 207. The locking block 206 will re-enter the interior of the second short shaft 205, limiting the second short shaft 205 and preventing the rubber roller 201 from rotating when it is not sliding under the non-ferrous metal. Therefore, it can be understood that when the non-ferrous metal slides sideways and drives the rubber roller 201 to rotate, the rubber roller 201 will drive the opening on the surface of the second short shaft 205 to rotate. So even if... After the transfer of non-ferrous metals is completed, the force spring 207 cannot push the force block 203 to reset. Therefore, it is also possible to observe whether the force block 203 can automatically reset to determine whether the rubber roller 201 rotates due to the slippage of the metal on the right side. When the slippage problem is found and the work is relatively busy, the rotating plate 9 can be rotated to drive the long shaft 8 and the connecting plate 7 to rotate 180 degrees, and rotate another unworn rubber pad 3 to the working position. When there is no time to spare, the worn rubber pad 3 can be disassembled and replaced. This can effectively avoid the problem of inconvenience in observing the early stage of aging and wear of the rubber pad 3.

[0023] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
