[0024] 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.

[0025] This utility model provides, for example Figure 1-5 The roll material hoist shown includes a fixed frame a1 and a fixed frame b8 installed on the right side of the fixed frame a1;

[0026] A crossbeam 6 is provided between the fixed frame a1 and the fixed frame b8;

[0027] A drive block 5 is fixedly connected to the lower outer wall of the crossbeam 6;

[0028] Inside the drive block 5, near the left and right sides, there are two winding machines 4. Both winding machines 4 are wound with cables 3. The other end of each cable 3 is fixedly connected to a hook 2. The lower side of the crossbeam 6 is provided with a roll body 10. The circular outer wall of the roll body 10 is fitted with a fixing buckle 9 near the left and right sides. When the operator starts the roll hoist, the motor of the drive block 5 starts to work, driving the winding machines 4 to run. The winding machines 4 start to wind the cables 3. When the drive shaft rotates, it tightens the cables 3 and causes the hooks 2 to move upward, thereby driving the roll body 10 to rise. During the retraction of the cables 3, the roll body 10 is safely lifted to the required height. Due to the presence of the fixing buckles 9, the tight connection between the cables 3 and the roll body is ensured, so that the roll body will not slip when lifted. When placing, the operator can control the reverse rotation of the drive block 5 to loosen the cables 3, so that the roll body 10 slowly descends to the designated position. The drive block 5 and the crossbeam 6 can move back and forth, thereby driving the roll body 10 to move.

[0029] Each of the two fixing buckles 9 has a groove 14 at one end, and a limit rod 16 is provided inside each of the two grooves 14. Limit grooves 18 are provided inside the drive block 5 and near the left and right sides respectively. Limit blocks 19 are fixedly connected to the upper outer walls of the two limit rods 16 to limit the maximum sway of the limit rods 16. When the roll body 10 sways back and forth during lifting or moving, the upper drive block 5 maintains a small sway to reduce the impact of sway. At this time, the limit rods 16 will collide with the inside of the grooves 14 on both sides as the roll body 10 moves, thereby limiting the sway of the roll according to the position of the upper drive block 5.

[0030] like Figure 4 and Figure 5 As shown, one end of each of the two fixed buckles 9 is fixedly connected to an extension plate 13 to provide the opening position of the groove 14. The inner walls of the front and rear ends of the two grooves 14 are fixedly connected to buffer blocks 15. The inside of the drive block 5 and near the left and right sides are fixedly connected to fixed blocks 17 to provide the opening position of the limiting groove 18. The multiple buffer blocks 15 are all made of rubber material. The lower side of the two limiting grooves 18 is provided with a movable groove to provide the back and forth swing range of the limiting rod 16.

[0031] The rubber material of the buffer block 15 can effectively absorb the impact force when the roll material shakes, reducing the vibration impact on the hoist. The extension and retraction of the limit rod 16 within the limit groove 18 is controlled by the drive motor. When the roll material body 10 shakes, the combination of the limit rod 16 and the limit groove 18 restricts its range of movement, preventing accidental fall due to excessive shaking.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the upper outer walls of the two fixing buckles 9 are fixedly connected with lifting rings 7 for the hooks 2 to fix. The lower outer walls of the fixing brackets a1 and b8 are fixedly connected with bases 11. The opposite sides of the fixing brackets a1 and b8 are fixedly connected with guide rails 12 to limit the movement direction of the drive block 5 and the crossbeam 6.

[0033] As the cable 3 retracts, the hook 2 is secured to the roll body 10 via the lifting ring 7, causing the roll to rise together. The presence of the guide rail 12 ensures that the drive block 5 and the crossbeam 6, guided by the fixing frame, move along the straight track, thereby keeping the roll rising process stable.

[0034] like Figure 1 and Figure 4 As shown, each of the two winding machines 4 is equipped with a drive motor. The two drive motors drive the two winding machines 4 to perform the winding and unwinding operations of the cable 3. The lower ends of the two fixing buckles 9 are flat, and the upper sides are round.

[0035] During operation, the drive motor starts working and contracts or relaxes its corresponding cable 3 according to the control command. The motor rotates and drives the winding machine 4 to interact with the cable 3, thereby realizing the lifting and lowering control of the roll material. The round upper design of the fixing buckle 9 allows it to naturally adapt to the shape of the roll material body 10, improving the reliability of gripping and ensuring that it is not easy to slip off during operation.

[0036] The implementation principle of this embodiment is as follows: The operator starts the roll material hoist, the motor of the drive block 5 starts working, driving the winding machine 4 to operate. The winding machine 4 begins to wind the cable 3. When the drive shaft rotates, it tightens the cable 3 and causes the hook 2 to move upward, thereby driving the roll material body 10 to rise. During the retraction of the cable 3, the roll material body 10 is safely lifted to the required height. Due to the presence of the fixing buckle 9, the tight connection between the cable 3 and the roll material is ensured, so that the roll material will not slip during lifting. When placing, the operator can... The reverse rotation of the drive block 5 is controlled to loosen the cable 3, allowing the roll body 10 to slowly descend to the designated position. The drive block 5 and the crossbeam 6 can move back and forth, thereby driving the roll body 10 to move. When the roll body 10 sways back and forth during lifting or moving, the upper drive block 5 maintains a small amplitude sway to reduce the impact of the sway. At this time, the limit rod 16 will collide with the grooves 14 on both sides as the roll body 10 moves, thereby limiting the sway amplitude of the roll according to the position limit of the upper drive block 5.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
