Description

Technical Field

[0001] This utility model belongs to the field of steel coil clamping technology, and in particular relates to a steel coil clamping device that prevents pinching injuries. Background Technology

[0002] In the steel production and processing, the hoisting of steel coils is a crucial step. Steel coils are typically made by winding steel strips, and during hoisting, steel coil clamps are needed for safe transfer. However, existing steel coil clamps are prone to causing injury during operation, especially to the beginning and end of the strip.

[0003] When hoisting steel coils with a thickness of 1.8mm-3.0mm, the camber at the beginning and end of the coil can cause overflow. When a crane hoists these coils, the clamps can easily damage and deform the beginning and end of the coil during the clamping process, resulting in squeezing and deformation at the overflow point, ultimately leading to scrap.

[0004] When clamps get stuck, it is extremely difficult to handle, often requiring electric welding to cut them. This not only damages the clamps but also poses safety risks to production workers, increasing their workload and operational risks.

[0005] In addition, the skill levels of crane operators vary, and there are instances of tilting and lifting during the hoisting process. This can cause the steel coil to collide with the clamp arm, further increasing the possibility of the steel coil being pinched at both ends. This can easily lead to problems in subsequent production processes, resulting in serious economic losses and increasing the production and processing costs of the steel coil. Utility Model Content

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a steel coil clamp to prevent pinching injury, including a clamp body 1. Both ends of the clamp body 1 are equipped with clamps 2 via a drive assembly 14. The clamping end of the clamp 2 is fixedly connected to a first pad 3. The top of the first pad 3 is provided with a protective curved surface 12 adapted to the steel coil. The inner side of the clamp 2 is fixedly connected to a second pad 4. The upper part of the inner side of the second pad 4 is provided with a protective inclined surface 10 that slopes downward from the outside to the inside. The bottom of the second pad 4 is provided with a protective arc surface 11 adapted to the steel coil.

[0019] In this embodiment, the fit between the protective curved surface 11 and the protective curved surface 12 and the cold-rolled coil is maximized in the contact width, which prevents the cold-rolled coil from lateral offset and overflow from both the aspects of contact adaptability and specification compatibility, and the tail anti-overflow part has a good pinching effect.

[0020] Furthermore, a pressure sensor 5 is installed inside the first pad 3, and an alarm 15 is installed on the surface of the clamp body 1.

[0021] In this embodiment, when the clamp is used to lift the steel coil, the first pad 3 first contacts the steel coil. The pressure sensor 5 monitors the pressure between the first pad 3 and the steel coil in real time. If the clamping force is too large due to improper operation or other reasons, and the pressure detected by the pressure sensor 5 exceeds the preset value, it will immediately transmit the signal to the control system. The control system will then control the alarm 15 to sound an alarm, reminding the operator to adjust the clamping force in time, thereby effectively avoiding damage to the steel coil due to excessive clamping force.

[0022] Furthermore, a hook assembly 13 is fixedly connected to the top of the clamp body 1, and an electrical control assembly 16 is fixedly connected to the top of the clamp body 1.

[0023] Furthermore, the inner side of the clamp 2 is provided with a receiving groove 9 that is adapted to the second pad 4, and a number of elastic elements 7 are horizontally fixedly connected between the outer side of the second pad 4 and the inner wall of the receiving groove 9.

[0024] Furthermore, the inner wall of the receiving groove 9 is provided with a guide rail 8 for guiding and limiting the movement of the second pad 4.

[0025] Furthermore, a protective layer 6 is fixedly connected to the inner side of the second pad 4, and the inclination angle of the protective slope 10 is 15° of the alarm.

[0026] Furthermore, the protective layer 6 is made of polyurethane, and the second pad 4 and the first pad 3 are both made of polyethylene rubber.

[0027] In this embodiment, the second pad 4 can slide relative to the clamp 2. The clamping end of the clamp 2 is provided with a guide rail 8. The second pad 4 is mounted on the guide rail 8. The side of the second pad 4 near the steel coil is provided with a protective layer 6. A spring is connected between the second pad 4 and the clamp 2 as an elastic element 7.

[0028] During hoisting, when the head or tail of the steel coil shifts, the second pad 4 will be subjected to the squeezing force of the steel coil.

[0029] The second pad 4 compresses the elastic element 7 and slides along the guide rail 8 to adapt to changes in the position of the steel coil. At the same time, the protective layer 6 on its surface can buffer and protect the coil, preventing the beginning and end of the coil from being pinched. When the hoisting is completed and the clamping force is removed, the spring will quickly reset the second pad 4 for the next use.

[0030] The protective bevel 10 can accommodate situations where the strip of cold-rolled coils of different specifications overflows, reducing the operating frequency of flame cutting personnel, improving operational safety, and reducing equipment investment costs and operational risks.

[0031] The protective layer 6 effectively absorbs impact force, avoiding surface pinching damage caused by traditional rigid contact, and provides good anti-pinch protection.

[0032] The working principle and usage process of this utility model are as follows: After the utility model is installed, when using the clamp to lift the steel coil, the first pad 3 first contacts the steel coil. The pressure sensor 5 monitors the pressure between the first pad 3 and the steel coil in real time. If the operator causes excessive clamping force due to improper operation or other reasons, and the pressure detected by the pressure sensor 5 exceeds the preset value, it will immediately transmit a signal to the control system. The control system will then control the alarm 15 to sound an alarm, reminding the operator to adjust the clamping force in time, thereby effectively avoiding damage to the steel coil due to excessive clamping force. The second pad 4 can slide relative to the clamp 2. The clamping end of the clamp 2 is provided with a guide rail 8. The second pad 4 is installed on the guide rail 8. The side of the second pad 4 closest to the steel coil is provided with a protective layer 6. A spring is connected between the second pad 4 and the clamp 2 as an elastic element 7. During lifting... During the process, when the head or tail of the steel coil shifts, the second pad 4 will be subjected to the squeezing force of the steel coil. The second pad 4 will compress the elastic element 7 and slide along the guide rail 8 to adapt to the position change of the steel coil. At the same time, the protective layer 6 on its surface can play a buffering and protective role, preventing the head and tail of the steel coil from being pinched. When the hoisting is completed and the clamping force disappears, the spring will make the second pad 4 quickly return to its original position for the next use. The fit between the protective arc surface 11 and the protective curved surface 12 and the cold-rolled coil and the maximum combination in the contact width prevent the cold-rolled coil from shifting laterally and overflowing from both the aspects of contact adaptability and specification compatibility. The anti-overflow part of the tail has a good pinching effect. The protective inclined surface 10 can adapt to most of the overflow of the head of the cold-rolled coil of different specifications, reduce the operation frequency of flame cutting personnel, improve the safety of operation, and reduce equipment investment costs and operation risks.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
