Description

Technical Field

[0001] This utility model relates to the field of cold-rolled strip steel handling technology, and more specifically, to a cold-rolled strip steel hoisting tool. Background Technology

[0002] In the metallurgical and metal processing industries, cold-rolled strip steel is widely used in automobile manufacturing, home appliances, precision instruments, and other fields due to its excellent surface finish, dimensional accuracy, and mechanical properties. During the production, transportation, and storage of cold-rolled strip steel, lifting equipment is typically required for handling to avoid deformation, scratches, or safety hazards caused by manual operation.

[0003] In the prior art, such as the cold-rolled strip steel lifting tool disclosed in CN208345580U, the lifting tool is composed of a first hook body and a second hook body. The first hook body and the second hook body are respectively installed at both ends of a connecting rod via a first hinge and a second hinge. The two work together to improve the stability of lifting and allow them to rotate on the connecting rod, enabling conversion between lifting and support. However, although the above-mentioned lifting tool can facilitate the lifting and transportation of cold-rolled strip steel coils after installation, on the one hand, because the lifting tool fixes the cold-rolled strip steel coil by inserting one end of the first hook body or the second hook body into the connecting rod, the disassembly and assembly of the cold-rolled strip steel coil is relatively inconvenient, thus greatly reducing the efficiency of lifting and transportation. On the other hand, because the structural dimensions of the above-mentioned lifting tool are fixed, it can only lift and transport cold-rolled strip steel coils with a specific inner diameter, reducing the adaptability of the lifting tool.

[0026] like Figures 1-3 As shown, a cold-rolled strip steel hoisting tool according to one embodiment of the present invention includes a workbench 1 and a hoisting clamp; a hoisting mechanism 2 is slidably mounted on the workbench 1, the hoisting mechanism 2 includes a swing arm 221 that can rotate and swing relative to the workbench 1; the hoisting clamp includes a clamping assembly 3 and a connecting seat 4 fixed on the swing arm 221, the clamping assembly 3 includes a driving member 31, a mounting sleeve 32 and a clamping toothed ring 33, the driving member 31 and the mounting sleeve 32 are both mounted on the connecting seat 4, the clamping toothed ring 33 is slidably fitted into the mounting sleeve 32, the mounting sleeve 32 and the inner ring of the clamping toothed ring 33 cooperate to form a clamping space for fixing the cold-rolled strip steel, a driving gear 34 is sleeved on the output end of the driving member 31, and the driving gear 34 meshes with the outer ring of the clamping toothed ring 33.

[0027] The aforementioned cold-rolled strip lifting tool is equipped with a swing arm 221. The rotation and swing of the swing arm 221 can control its position adjustment, thereby enabling the clamping assembly 3 to reciprocate towards the cold-rolled strip, facilitating the lifting and transfer of the cold-rolled strip. A drive component 31 is provided, which controls the sliding state of the clamping toothed ring 33 within the mounting sleeve 32, thereby adjusting the size of the clamping space to accommodate cold-rolled strips with different inner diameters. The clamping space utilizes the gap between the mounting sleeve 32 and the inner ring of the clamping toothed ring 33 to clamp and fix the cold-rolled strip, improving the stability during transfer. Furthermore, the sliding installation of the clamping toothed ring 33 facilitates the loading and unloading of the cold-rolled strip.

[0028] Specifically, the clamping space between the mounting sleeve 32 and the inner ring of the clamping toothed ring 33 is a circular space. This adapts to the shape of the cold-rolled strip steel coil, which is beneficial for clamping and fixing the cold-rolled strip steel.

[0029] Furthermore, the outer ring of the clamping toothed ring 33 is provided with toothed patterns.

[0030] like Figure 2 As shown, in one embodiment, the top of the workbench 1 is provided with a guide rail 11, and there are two hoisting mechanisms 2, which are slidably mounted on both ends of the guide rail 11.

[0031] Specifically, the guide rail 11 is arranged in a horizontal direction.

[0032] like Figure 1 and Figure 2 As shown, in one embodiment, the bottom of the workbench 1 is equipped with multiple casters 12 and multiple telescopic legs 13. The casters 12 and telescopic legs 13 are spaced apart. The telescopic legs 13 can be raised and lowered relative to the workbench 1, and a caster 12 is provided between two adjacent telescopic legs 13. This facilitates the movement or fixing of the workbench 1.

[0033] like Figure 1 and Figure 2 As shown, in one embodiment, the lifting mechanism 2 includes a rotating disk 21, a lifting assembly 22, and a sliding seat 23 slidably mounted on a guide rail 11. The rotating disk 21 is rotatably mounted on the sliding seat 23, and the lifting assembly 22 is fixed on the rotating disk 21. Thus, by providing the sliding seat 23, the sliding of the sliding seat 23 on the guide rail 11 can drive the lifting assembly 22 to move, thereby completing the transfer of the cold-rolled strip steel; by providing the rotating disk 21, the rotation of the rotating disk 21 on the sliding seat 23 can drive the lifting assembly 22 to rotate, thereby adjusting the clamping angle of the cold-rolled strip steel, and thus improving the clamping accuracy of the cold-rolled strip steel.

[0034] like Figure 2 As shown, in one embodiment, the hoisting mechanism 2 further includes a first drive motor 24 and a second drive motor 25. The first drive motor 24 is mounted on the sliding seat 23 and is used to control the sliding state of the sliding seat 23 on the guide rail 11. The second drive motor 25 is mounted on the rotating disk 21 and is used to control the rotation state of the rotating disk 21 on the sliding seat 23.

[0035] like Figure 2As shown, in one embodiment, the lifting assembly 22 includes a mounting arm 222, a support frame 223, and a drive cylinder 224. One end of the mounting arm 222 is fixed to the rotating disk 21, and the other end of the mounting arm 222 is rotatably connected to the swing arm 221. The support frame 223 is disposed between the mounting arm 222 and the rotating disk 21. One end of the drive cylinder 224 is mounted on the mounting arm 222, and the other end of the drive cylinder 224 is drively connected to the swing arm 221. Thus, by providing the support frame 223, the fixing of the mounting arm 222 is reinforced, thereby improving the stability of the mounting arm 222 when fixed. By providing the drive cylinder 224, the drive cylinder 224 controls the swing of the swing arm 221, thereby enabling the clamping assembly 3 on the swing arm 221 to reciprocate and adjust its height position, thereby reciprocating and approaching the cold-rolled strip steel, facilitating the clamping and subsequent transfer of the cold-rolled strip steel.

[0036] like Figure 2 As shown, in one embodiment, a disassembly rod 225 is movably inserted into the swing arm 221, and the connecting seat 4 is detachably fixed to one end of the disassembly rod 225 that protrudes from the outside of the swing arm 221. The disassembly rod 225 can extend or shorten the overall length of the swing arm 221, thereby adjusting the transfer radius of the clamping assembly 3 to meet the needs of different production scenarios.

[0037] like Figure 3 As shown, in one embodiment, a protrusion 41 is integrally formed at the center of the connecting seat 4. The protrusion 41 is detachably fixed to the disassembly rod 225, and two clamping components 3 are symmetrically arranged on both sides of the protrusion 41. The two ends of the cold-rolled steel strip are clamped simultaneously to ensure stability during clamping and transportation, avoid the cold-rolled steel strip from falling off due to collisions or other accidents, and improve the efficiency of hoisting and transportation.

[0038] like Figure 3 As shown, in one embodiment, the driving component 31 includes a third driving motor 311 and a transmission structure 312. The third driving motor 311 is mounted on the connecting seat 4 and is connected to one end of the transmission structure 312. A driving gear 34 is sleeved on the other end of the transmission structure 312.

[0039] like Figure 3 and Figure 4As shown, in one embodiment, multiple sets of meshing teeth 341 are integrally connected to the outer periphery of the drive gear 34. Each set of meshing teeth 341 has an anti-slip protrusion 342 on its top. A tooth groove 343 is formed between two sets of meshing teeth 341. A wear-resistant layer 344 is fixedly laid on the top surface of the tooth groove 343, and an anti-slip layer 345 is coated on the surface of the wear-resistant layer 344. The tooth groove 343 serves as the contact surface with the outer ring of the clamping tooth ring 33, and its wear rate is relatively fast. Therefore, a wear-resistant layer 344 is provided in the tooth groove 343 to improve the service strength of the tooth groove 343, effectively extend the wear time at the tooth groove 343, and thus extend the service life of the drive gear 34. In addition, the anti-slip layer 345 coated on the surface of the wear-resistant layer 344 can increase the contact friction between the tooth groove 343 and the outer ring of the clamping tooth ring 33, ensuring the normal operation of the tooth groove 343 and the outer ring of the clamping tooth ring 33, and further improving the stability of use.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
