Description

Technical Field

[0001] This utility model relates to the field of steel strip hoisting technology, specifically a special hoisting tool for hoisting bare packaged steel strips with double fork teeth. Background Technology

[0002] In the production, storage and transportation of bare packaged steel strip (coiled steel strip without outer packaging protection), it is necessary to use lifting equipment to achieve rapid lifting. At present, steel ropes are commonly used as the main lifting tools in the industry. The operation method is mostly to pass the steel rope through the inner hole or bottom surface of the steel strip coil, and use the steel rope to bear the weight and cooperate with the lifting equipment to complete the lifting.

[0003] However, in existing steel rope hoisting methods, the steel rope is in direct contact with the bottom surface of the steel strip. When under load, the steel rope contracts due to tension, which can cause compression and friction on the surface of the steel strip, easily resulting in scratches and indentations. This is especially true for steel strips with high surface finish requirements (such as cold-rolled stainless steel strips), where the probability of damage increases significantly. At the same time, it is difficult to achieve uniform distribution of the steel rope around the circumference of the steel strip. During hoisting, the force on the steel strip is concentrated at the contact point of the steel rope, which can easily lead to tilting, deformation, or even unwinding of the roll, resulting in poor stability. Furthermore, the operation of threading the steel rope is cumbersome, requiring manual adjustment of the position to avoid uneven loading, which reduces hoisting efficiency. Therefore, there is an urgent need for a special hoisting tool with double forks for hoisting bare packaged steel strips to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a special lifting tool for lifting bare packaged steel strips with double fork teeth, so as to solve the problems mentioned in the background art, which are that when the steel rope is under load, the tension contraction of the steel rope will cause compression and friction on the surface of the steel strip, which will easily cause scratches on the surface of the steel strip. At the same time, it is difficult to achieve uniform distribution of the steel rope in the circumferential direction of the steel strip, and the operation of winding the steel rope is cumbersome.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a special lifting device for transporting bare packaged steel strips using a double-forked tooth method, including a connecting frame, and further comprising: A quick-lift assembly is provided on the bottom surface of the connecting frame and is used for quick hooking and lifting of the steel strip; A limiting guide component is disposed on the bottom surface of the connecting frame and is used to limit and guide the quick transport component.

[0009] Preferably, the inner wall of the guide block is fixedly connected to a connecting column, and multiple connecting buckles are provided between the connecting frame and the quick transport component. The multiple rotating columns are divided into four groups. In each group, the connecting buckle in the upper position is movably sleeved with the connecting column, and in each group, the connecting buckle in the lower position is movably sleeved with the connecting hole. Adjacent multiple connecting buckles are movably sleeved with each other.

[0010] Preferably, the surfaces of the double-fork hook and the sliding fork are provided with multiple anti-slip grooves, and the dimensions of the multiple anti-slip grooves are matched.

[0011] Compared with the prior art, the beneficial effects of this utility model are: The quick-lifting components facilitate the rapid lifting of dry steel strips using multiple double-fork hooks, thus avoiding the probability of damage to the steel strip caused by the shrinkage of the steel strip under load when the traditional steel rope passes through it.

Detailed Implementation

[0014] 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.

[0015] Please see Figure 1 - Figure 4 This utility model provides a special lifting tool for lifting bare packaged steel strips with double fork teeth, including a connecting frame 1, and also includes: The quick-lifting component is located on the bottom surface of the connecting frame 1 and is used for quick hooking and lifting of the steel strip; A limit guide component is provided on the bottom surface of the connecting frame 1 and is used to limit and guide the quick transport component. The quick-access transport components facilitate rapid hoisting of dry steel strips, thus avoiding the probability of damage to the steel strip caused by the shrinkage of the steel strip under load when the traditional steel rope passes through it. At the same time, the limit and guide components facilitate the limit and guide of multiple hooks, thereby ensuring even force distribution during steel strip hoisting and improving hoisting stability.

[0016] Furthermore, the quick-transfer assembly includes multiple double-fork hooks 201, all of which are disposed on the bottom surface of the connecting frame 1. Sliding grooves 202 are provided on both sides of the inner wall of each double-fork hook 201. Sliding blocks 203 are slidably connected to the inner wall of each sliding groove 202. The same sliding fork 204 is slidably connected to the side walls of two sliding blocks 203. Threaded holes 205 are provided on the side walls of the double-fork hooks 201, and rotating grooves 206 are provided on the side walls of the sliding forks 204. A screw thread is rotatably connected to the inner wall of the rotating groove 206. The threaded post 207 has its surface threaded to the inner wall of the threaded hole 205. A positioning nut 208 is threaded onto the surface of the threaded post 207, with one end abutting against the side wall of the double-fork hook 201. Multiple anti-slip grooves 209 are provided on both the surface of the double-fork hook 201 and the surface of the sliding fork 204. These anti-slip grooves 209 are sized to match. Through the designed quick-release assembly, the multiple double-fork hooks 201 are evenly distributed during their coordinated operation. The multiple double-fork hooks 201, placed on the bottom surface of the steel strip, facilitate hooking and lifting. Their simple structure and easy operation reduce labor intensity, thus effectively improving production efficiency. The simple structure of the multiple double-fork hooks 201 also reduces manufacturing costs. Furthermore, the use of multiple double-fork hooks 201 avoids the probability of damage to the steel strip caused by the shrinkage of the steel rope passing through the bottom surface under load, a common problem with traditional steel rope lifting. Additionally, the coordinated use of the sliding fork 204, sliding groove 202, and sliding block 203 allows the rotating threaded column 207 to move the sliding fork 204, changing the contact area between the double-fork hooks 201 and the steel strip, thereby improving the stability of steel strip transport. The positioning nut 208 allows for limiting the adjustment of the threaded column 207, enabling the sliding fork 204 to slide back and forth. The multiple anti-slip grooves 209 increase the friction between the double-fork hooks 201 and the steel strip when they contact it.

[0017] Furthermore, the limiting and guiding assembly includes multiple guide blocks 301, all of which are disposed on the bottom surface of the connecting frame 1. Rotation holes 302 are formed on the side walls of the guide blocks 301. Multiple limiting grooves 303 are formed on the bottom surface of the connecting frame 1. Rotating columns 304 are fixedly connected to the inner walls of the limiting grooves 303. The inner walls of the rotation holes 302 are rotatably connected to the surface of the rotating columns 304. A connecting hole 306 is formed on the side wall of the double-fork hook 201. A connecting column 305 is fixedly connected to the inner wall of the guide blocks 301. Multiple connecting buckles 307 are provided between the connecting frame 1 and the quick-transfer assembly. The multiple rotating columns 304 are divided into four groups. In each group, the upper connecting buckle 307 is movably sleeved with the connecting column 305, and in each group, the lower connecting buckle 307 is movably sleeved with the connecting hole 306. Adjacent connecting buckles 307 are movably sleeved together. The limiting and guiding mechanism is activated by the set limiting... The guide assembly ensures that multiple limiting grooves 303 are evenly distributed, facilitating the limiting and guiding of the rotation direction of the connecting column 305 via the rotating column 304. The multiple rotating columns 304, in conjunction with the guide block 301, ensure that the multiple double-fork hooks 201 are evenly distributed around the circumference of the steel strip during lifting. This even distribution of hooks ensures uniform force distribution on the steel strip during lifting, reducing the probability of detachment due to uneven weight distribution. Simultaneously, the multiple connecting buckles 307 work together, with four sets of matching lengths, ensuring even contact between the multiple double-fork hooks 201 and the bottom surface of the steel strip during lifting, further improving lifting stability. Furthermore, the multiple connecting buckles 307 are movably interlocked, facilitating storage after lifting. Working Principle: The quick-access assembly allows for the coordinated use of multiple double-fork hooks 201, evenly distributed on the bottom surface of the steel strip, facilitating hooking and lifting. The simple structure and easy operation of the multiple double-fork hooks 201 reduce labor intensity, thus improving production efficiency. Furthermore, the simple structure of the multiple double-fork hooks 201 lowers manufacturing costs. Secondly, the hooking method using multiple double-fork hooks 201 avoids the probability of damage to the steel strip caused by the shrinkage of the steel rope passing through the bottom surface under load, a common problem with traditional steel rope lifting. Thirdly, the coordinated use of the sliding fork 204, sliding groove 202, and sliding block 203 allows the rotating threaded column 207 to move the sliding fork 204, changing the contact area between the double-fork hooks 201 and the steel strip, thereby improving the stability of the steel strip transport.

[0018] By setting the limiting guide component, multiple limiting grooves 303 are evenly distributed, which facilitates the limiting and guiding of the rotation direction of the connecting column 305 by the rotating column 304. The multiple rotating columns 304 and the guide block 301 work together to facilitate the even distribution of multiple double-fork hooks 201 around the circumference of the steel strip when lifting. The even distribution of multiple double-fork hooks 201 around the circumference of the steel strip when lifting makes it easier for the steel strip to be evenly stressed during lifting, thereby reducing the probability of the steel strip falling off due to uneven distribution of the center of gravity during the lifting process.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
