[0002] During the film production process, film rolls cut to customer specifications need to be hoisted to designated locations for packaging and then moved to warehouses for centralized storage and transportation. The core of a film roll is typically a hollow paper tube. Currently, the simplest method for hoisting it involves inserting a steel pipe through the tube and attaching slings to each end. However, during this process, the slings create an angle of approximately 60° between the corners of the roll's end and the overhead crane hook, which can easily damage the film, affecting product quality and causing financial losses. To address this issue, we propose a dedicated hoist for finished film. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] A special sling for finished film, such as Figures 1-4 As shown, it includes a support frame 1;

[0025] The support frame 1 is provided with a clamping mechanism 2, which can clamp and fix the steel pipe supporting the film roll, thereby keeping the film roll stable when the film roll is moved.

[0026] Specifically, the clamping mechanism 2 includes a sling 201, which is connected to both ends of the support frame 1. The sling 201 mechanism can suspend the film roll, thereby realizing the mobile transportation operation of the film roll. The end of the sling 201 is connected to a clamping seat 202, and the inner side of the clamping seat 202 is fixedly connected to a clamping column 203. The clamping column 203 is a cylindrical structure. At the same time, the diameter of the clamping column 203 is close to the inner diameter of the steel pipe, so that the clamping column 203 can be inserted into the steel pipe, and the clamping seat 202, the steel pipe and the film roll can be kept stable when the film roll is suspended. At the same time, the length of the clamping seat 202 is greater than the radius of the film roll. During transportation, the clamping seat 202 is on both sides of the film roll, so that the film roll can be shaped to prevent the film roll from being offset due to shaking during movement, forming a conical structure at one end, affecting the subsequent storage of the film roll. A fixing groove 204 is provided on the inner side of the clamping seat 202. The fixing groove 204 structure can position the steel pipe, and the top of the fixing groove 204 is connected to the interior of the clamping seat 202. A friction block 205 is slidably connected to the interior of the clamping seat 202. The ends of the suspension rope 201 are fixedly connected to both sides of the friction block 205. The friction block 205 structure can slide inside the hollow clamping seat 202 and clamp and fix the steel pipe from the top of the fixing groove 204. The clamping column 203 passes through the clamping seat 202 and is connected to the interior of the clamping seat 202, while the suspension rope 201 is set from the bottom of the clamping column 203 around the clamping column 203. When the suspension rope 201 is subjected to an upward pulling force, the bottom of the suspension rope 201 will drive the friction block 205 to move downward, thereby cooperating with the clamping column 203 to clamp and fix the steel pipe.

[0027] A cable drum 206 is slidably connected to the support frame 1, and the suspension rope 201 is wound around the cable drum 206. The cable drum 206 can store the suspension rope 201. A clamping rope 207 is fixedly connected to the inside of the cable drum 206. The clamping rope 207 passes through the middle of the support frame 1. The clamping rope 207 structure can drive the cable drums 206 to move closer to each other. A return spring 208 is fixedly connected to the outside of the cable drum 206. The reset end is fixedly connected to the clamping frame. The return spring 208 structure can reset the cable drum 206, allowing the cable drum 206 to move to the sides when not being pulled by the clamping rope 207, thereby facilitating the movement and reset of the cable drum 206.

[0028] A lifting lug 3 is fixedly connected to the center of the top of the support frame 1. A positioning slot 4 is defined in the center of the lifting lug 3. The positioning slot 4, located inside the lifting lug 3, is configured to engage with a hook. The center of the clamping rope 207 corresponds to the positioning slot 4. The clamping rope 207 can be pulled by the hook, which moves vertically within the positioning slot 4, thereby driving the movement of the cable drum 206.

[0029] Example 2

[0030] like Figure 1 、 Figure 4 As shown, on the basis of embodiment 1, a fastening mechanism 5 is provided on the clamping seat 202, and the fastening mechanism 5 can fasten the inner side of the steel pipe, thereby improving the stability of the steel pipe.

[0031] In this embodiment, the fastening mechanism 5 includes a clamping rod 501, which is movably connected to the inside of the clamping column 203. The end of the clamping rod 501 is fixedly connected to a fastening block 502. There are two clamping rods 501. The two clamping rods 501 can be rotated outward and clamp and fasten the inner walls of both sides of the steel pipe through the fastening block 502.

[0032] Clamping slots 503 corresponding to the clamping rod 501 structure are opened on both sides of the clamping column 203. The clamping rod 501 is connected inside the clamping slots 503. The clamping slots 503 structure can facilitate the clamping rod 501 to rotate outward from the inside of the clamping column 203.

[0033] A driving rod 504 is slidingly connected inside the clamping groove 503. The driving rod 504 is an "L"-shaped structure. The end of the driving rod 504 is rotatably connected to the end of the clamping rod 501. The driving rod 504 structure can drive the clamping rod 501. The movement of the driving rod 504 drives the end of the clamping rod 501 to rotate outward to achieve a clamping effect.

[0034] A rotating rod 505 is rotatably connected to the clamping seat 202. The rotating rod 505 supports the clamping rod 501, allowing it to rotate outward, thereby achieving a stable clamping effect on the steel pipe. A movable slot 506 is provided through the side of the rotating rod 505, and the clamping rod 501 is slidably connected within the movable slot 506. The rotating rod 505 structure can easily limit the clamping rod 501, allowing the clamping rod to slide and adjust along the clamping rod direction within the movable slot.

[0035] When using the dedicated sling for finished film of the present invention, the support frame 1 is first moved to the film roll to be moved. To facilitate the movement and transportation of the film roll, a steel pipe is inserted into the paper tube in the middle of the film roll. The clamping seat 202 is then moved to both sides of the film roll. After the sling rope 201 is unwound from the outside of the cable drum 206 to an appropriate length, the cable drum 206 is locked. The clamping seat 202 and the clamping column 203 are then pressed into the interior of the steel pipe. The hollow steel pipe is sleeved on the outside of the clamping column 203 and continuously moved along the clamping column 203 toward the fixed groove 204. During the movement, the end of the steel pipe pushes the drive rod 504 to move. The drive rod 504 then drives the clamping rod 501 to rotate through the end, and the clamping rod 501 rotates around the rotating rod 505 under the drive of the drive rod 504. At the same time, since the end of the clamping rod 501 moves with the driving rod 504, the rotation point of the clamping rod 501 continues to move toward the end of the clamping rod 501 during the rotation of the clamping rod 501. After the steel pipe is clamped and fixed by the fastening block 502 at the end of the clamping rod 501, the support frame 1 and the film roll are then moved and transported by the lifting equipment. The hook of the lifting equipment moves upward along the positioning groove 4 and drives the middle of the clamping rope 207 upward. The two ends of the clamping rope 207 then drive the cable drum 206 inward. The cable drum 206 drives the clamping seat 202 diagonally upward through the suspension rope 201, causing the clamping seat 202 to be subjected to an inward force, thereby pressing the clamping seat 202 toward the steel pipe. As the steel pipe continues to approach the clamping seat 202, it again applies force to the drive rod 504 toward the clamping seat 202, rotating the clamping rod 501 outward. This increases the clamping force on the steel pipe through the fastening block 502 at the end of the clamping rod 501. Once the film roll is suspended in the air, it drives the clamping seat 202 downward, exerting a force upward on the suspension rope 201. The friction block 205 at the end of the suspension rope 201 then moves downward and cooperates with the clamping column 203 to securely clamp the steel pipe.
