Description

Technical Field

[0001] This utility model relates to the field of steel coil hoisting technology, specifically a chain-type anti-wear steel coil hoisting tool. Background Technology

[0002] In the steel and non-ferrous metal processing and logistics sectors, the hoisting and transfer of steel coils is a crucial step in the production process. Traditional steel coil lifting tools generally use wire ropes or nylon slings as the main load-bearing components, which have revealed significant technical defects in actual operation. Wire rope lifting tools generate severe friction when in contact with the edge of the steel coil, accelerating the wear of the lifting tool itself and leaving scratches on the surface of the steel coil, seriously affecting product quality. Simultaneously, due to the lack of effective anti-slip mechanisms, the steel coil is prone to swaying or even tipping over during hoisting, posing a significant safety hazard. While existing chain lifting tools improve wear resistance to some extent, their rigid connection method makes threading difficult, especially when handling horizontally laid steel coils. Operators often need to repeatedly adjust the lifting tool position, severely impacting operational efficiency.

[0003] Furthermore, the fixed structure of traditional lifting tools is difficult to adapt to the lifting needs of steel coils of different specifications. When facing diverse production tasks, enterprises often need to equip themselves with multiple sets of specialized lifting tools, which increases equipment costs and creates a burden on storage management. These technical limitations seriously restrict the development of automation in modern steel logistics, so there is now a need for a chain-type wear-resistant steel coil lifting tooling. Utility Model Content

[0004] The purpose of this utility model is to provide a chain-type anti-wear steel coil lifting fixture, which significantly improves the safety, stability and durability of steel coil lifting through innovative structural design and multi-component synergy, thereby solving the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chain-type anti-wear steel coil lifting fixture, comprising a large lifting ring, a chain used in conjunction with the large lifting ring, small lifting rings respectively installed at both ends of the chain, and a C-shaped hook for connecting two sets of the small lifting rings;

[0006] The large lifting eye includes a large lifting eye plate, with two sets of large lifting eye support plates symmetrically installed at the bottom of the large lifting eye plate. A set of chain locking pins is elastically installed between the two sets of large lifting eye support plates. A large lifting eye pulley is rotatably installed between the two sets of large lifting eye support plates, located below the chain locking pins. The chain passes between the chain locking pins and the large lifting eye pulleys, and the small lifting eyelets at both ends of the chain are movably fastened by C-shaped hooks.

[0007] Preferably, the large lifting ring plate has a connecting hole through the center, a spring is fixedly installed at the bottom of the large lifting ring plate, two sets of large lifting ring support plates have symmetrical sliding grooves through them, the two ends of the chain lock pin are slidably installed against the inner wall of the sliding groove, and the bottom end of the spring is fixedly connected to the chain lock pin.

[0008] Preferably, the large lifting eye cylindrical pin is installed between two sets of large lifting eye support plates, and both ends of the large lifting eye cylindrical pin pass through the large lifting eye support plates for installation, and the large lifting eye pulley is rotated and sleeved on the outer arc surface of the large lifting eye cylindrical pin.

[0009] Preferably, the chain includes several sets of chain plates with pins and chain plates, each set of chain plates is connected through the chain plates with pins to form chain links, and each set of chain links is connected by riveting.

[0010] Preferably, the small eyelet includes two sets of eyelet buckles connected to both ends of the chain, with a hook opening through the center of each eyelet buckle. A positioning plate is installed at the bottom of each eyelet buckle corresponding to the end link of the chain, and the end link of the chain and the positioning plate are riveted together by the small eyelet pin.

[0011] Preferably, the C-shaped hook has an opening on one side, and the two sets of small lifting rings are respectively hooked to the two hook points inside the C-shaped hook through the opening.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This chain-type wear-resistant steel coil lifting fixture significantly improves the safety and efficiency of steel coil lifting through its innovative structural design. The coordinated design of the large lifting ring and chain ensures stable control of steel coil lifting. The chain can flexibly pass through the center of the steel coil and form a closed loop through the C-hook, effectively preventing swaying and slippage during lifting. The elastically installed chain pins continuously press the chain under the action of springs, preventing the chain from springing up or folding due to sudden changes in force. At the same time, the rotating large lifting ring pulley reduces friction when the chain is pulled, protecting the chain and improving operational smoothness. The densely riveted chain link structure and reinforced pin chain plate design enhance the overall load-bearing capacity of the chain, preventing the risk of breakage due to excessive weight of the steel coil. The flexible connection method of the small lifting ring and C-hook simplifies the chain threading and locking steps, and is especially suitable for the flipping operation when the steel coil is laid horizontally. Through multiple wear-resistant and anti-slip designs, this fixture not only extends its service life but also significantly reduces the risk of surface damage to the steel coil, balancing lifting efficiency and operational safety.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1-5 As shown, this utility model provides a chain-type anti-wear steel coil lifting fixture, including a large lifting ring 1, a chain 2 used in conjunction with the large lifting ring 1, small lifting rings 3 respectively installed at both ends of the chain 2, and a C-shaped hook 4 for connecting the two sets of small lifting rings 3. The large lifting ring 1 is hooked to the lifting equipment to ensure the device's control over the lifting of the steel coil 15, while the large lifting ring 1 limits the chain 2 to ensure that the chain 2 can flexibly cooperate with the steel coil 15, thus passing through the center of the steel coil 15, and the C-shaped hook 4 stably hooks the two sets of small lifting rings 3 to complete the closed loop of the chain 2, thereby ensuring stability during the lifting process of the steel coil 15.

[0022] The large lifting eye 1 includes a large lifting eye plate 5. Two sets of large lifting eye support plates 6 are symmetrically installed at the bottom of the large lifting eye plate 5. A chain lock pin 8 is elastically installed between the two sets of large lifting eye support plates 6. A large lifting eye pulley 10 is rotatably installed between the two sets of large lifting eye support plates 6, located below the chain lock pin 8. The chain 2 passes between the chain lock pin 8 and the large lifting eye pulley 10, and the small lifting eye 3 at both ends of the chain 2 is movably fastened by C-shaped hooks 4. The large lifting eye support plate 6 installed at the bottom of the large lifting eye plate 5 limits the spring 7 and the large lifting eye pulley 10. The spring 7 fixedly installed at the bottom of the large lifting eye plate 5 can apply a downward force to the chain lock pin 8 to ensure that the chain 2 will not bounce due to the force when lifting the steel coil 15. In addition, since the large lifting eye pulley 10 is rotatably installed, it can better cooperate with the chain 2 to ensure the flexibility of the chain 2.

[0023] A connecting hole is provided through the center of the large lifting eye plate 5. A spring 7 is fixedly installed at the bottom of the large lifting eye plate 5. Two sets of large lifting eye support plates 6 are symmetrically provided with sliding grooves. The two ends of the chain lock pin 8 are slidably installed against the inner wall of the sliding groove, and the bottom end of the spring 7 is fixedly connected to the chain lock pin 8. The connecting hole provided through the center of the large lifting eye plate 5 makes it more convenient to connect the whole device with the external structure, and can be better used with different lifting equipment. The spring 7 applies pressure to the chain lock pin 8, so that the chain lock pin 8 can stably press the chain 2 against the surface of the large lifting eye pulley 10 for operation, and ensure that the chain 2 will not fold during the pulling process, thus improving its safety during use. The sliding grooves restrict the position of the chain lock pin 8 during lifting, which can further improve the safety and stability of the device.

[0024] The large lifting eye cylindrical pin 9 is installed between two sets of large lifting eye support plates 6, and both ends of the large lifting eye cylindrical pin 9 pass through the large lifting eye support plate 6. The large lifting eye pulley 10 rotates and is sleeved on the outer arc surface of the large lifting eye cylindrical pin 9. The installation of the large lifting eye cylindrical pin 9 limits the movement of the large lifting eye pulley 10, ensuring that the large lifting eye pulley 10 will not be displaced. In addition, the large lifting eye pulley 10 is set to rotate, which minimizes the movement of the chain 2 when it is being pulled, and improves the overall service life of the device.

[0025] The chain 2 includes several sets of pin-plate chain 11 and chain plate 12. Each set of chain plate 12 is connected to the pin-plate chain 11 to form a chain link. The chain links are riveted together. The chain 2 improves its strength through the cooperation of several sets of pin-plate chain 11 and chain plate 12. The connection method between the chain links ensures that the chain plates 12 are densely arranged, which enhances its strength to bear the steel coil 15 and avoids the chain breaking during the lifting process.

[0026] It is worth noting that the small lifting eye 3 includes two sets of lifting eye buckles 13 connected to both ends of the chain 2. The center of the lifting eye buckle 13 has a hook opening, and the bottom of the lifting eye buckle 13 is equipped with a positioning plate corresponding to the end link of the chain 2. The end link of the chain 2 and the positioning plate are riveted together by the small lifting eye pin 14. The positioning plate installed at the bottom of the lifting eye buckle 13 for riveting the end link of the chain 2 makes the chain 2 and the small lifting eye 3 more flexible when connected as a whole. It can pass through the center of the steel coil 15 and be locked by the C-shaped hook 4, ensuring the convenience of the lifting process.

[0027] Specifically, an opening is provided on one side of the C-hook 4, and two sets of small lifting rings 3 are hooked to two hook points inside the C-hook 4 through the opening. The opening on one side of the small lifting ring pin 14 allows both sets of small lifting rings 3 to enter the C-hook 4 through the opening. The C-shaped structure of the C-hook 4 allows it to stably hook the two sets of small lifting rings 3 to complete the limiting. When the steel coil 15 is laid horizontally, the entire device is connected to the external lifting structure and adjusted to an appropriate height so that the small lifting ring 3 at one end of the chain 2 passes through the bottom surface of the steel coil 15. The two sets of small lifting rings 3 are connected by the C-hook 4 to ensure that the steel coil 15 slowly rotates. During the lifting process, the C-hook 4 will be driven by the large lifting ring pulley 10, and the chain locking pin 8 will exert force on the chain 2, which can prevent the chain 2 from moving and causing wear on the steel coil 15.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
