[0024] See also Figure 1 and Figure 2 The present invention provides a sling, comprising a main body 1 and mechanical arms 2 arranged at both ends of the main body 1. Preferably, the main body 1, as the main supporting component, needs to meet certain strength requirements. Therefore, the material of the main body 1 is steel. The mechanical arm 2 is movably connected to the main body 1, and the position of the mechanical arm 2 can be appropriately adjusted according to specific usage requirements, so as to adjust the distance between the two mechanical arms 2 to meet the needs of membranes of different sizes. At least one positioning hole 3 is provided on the mechanical arm 2, and a positioning groove matching the positioning hole 3 is provided on the main body 1. A first latch 4 is provided between the positioning hole 3 and the positioning groove. The positioning hole 3, the positioning groove and the first latch 4 are used to fix and limit the position of the mechanical arm 2 to prevent the mechanical arm 2 from loosening or slipping from the main body 1. The utility model can improve work safety, and at the same time avoid the phenomenon of sliding of the mechanical arm 2 during transportation, thereby improving work stability. At least one lifting ring 5 is provided on the main body 1 or the mechanical arm 2, and the number of the lifting rings 5 can be set according to specific use requirements, and the lifting rings 5 can be selected to be set on the main body 1 or on the mechanical arm 2. The driving crane is connected to the lifting ring 5 through a lifting rope. The overall volume of the utility model is small, no electrical device is required, it is easy to use and has a long service life, low installation space requirements, and can quickly switch widths; and the mechanical arm 2 is used to replace the iron rod and the lifting belt for hanging, which reduces the possibility of damage to the membrane material and personnel safety, effectively improves the safety and stability of use, and can also greatly reduce the labor intensity of the staff and improve work efficiency.

[0025] As an embodiment of the present utility model, the robotic arm 2 includes a connecting portion 21 connected to the main body 1, and an extension portion 22 extending downward is provided at one end of the connecting portion 21 away from the main body 1, and a bearing portion 23 extending toward the other robotic arm 2 is provided at one end of the extension portion 22 away from the connecting portion 21. The bearing portions 23 of the two robotic arms 2 are arranged opposite to each other, and the suspended film material is located between the two extension portions 22 and is carried and transported by the two bearing portions 23. The two connecting portions 21 are used to adjust the positional relationship between the robotic arm 2 as a whole and the main body 1 to meet the requirements of the film material.

[0026] As an embodiment of the present invention, the extension part 22 is perpendicular to the connecting part 21 and the bearing part 23, and the bearing part 23 is parallel to the connecting part 21. The connecting part 21, the extension part 22, and the bearing part 23 are in a mutually perpendicular relationship, which can effectively improve the overall connection strength of the robotic arm 2, thereby improving the overall service life and working stability. When the staff places the film material on the bearing part 23, due to the adoption of a mutually perpendicular structure, the staff's operating space is spacious, effectively avoiding unnecessary interference between the extension part 22 or the connecting part 21 and the film material or the staff's body, reducing the difficulty of operation, and effectively avoiding collision between the staff and the extension part 22 or the connecting part 21 during the placement of the film material, thereby improving work safety.

[0027] As an embodiment of the present invention, the length of the connecting portion 21 is L, and the length of the main body 1 is S, satisfying: S / 3<L<S / 2, which can effectively improve the adjustment range of the robotic arm 2 and improve the overall scope of use. At the same time, it can also reduce the length of the robotic arm 2 to a certain extent, avoid material waste caused by the robotic arm 2 being too long, and effectively reduce costs.

[0028] As an embodiment of the present invention, the connecting part 21 is a hollow connecting rod with an open end. The first end of the main body 1 is inserted into one connecting part 21, and the second end of the main body 1 is inserted into another connecting part 21. Compared with the external connection relationship between the main body 1 and the robotic arm 2, such as surface welding, the connection structure through which the main body 1 is inserted into the connecting part 21 can effectively improve the connection strength between the main body 1 and the robotic arm 2, improve the working stability, and at the same time avoid the phenomenon of the robotic arm 2 falling off due to insufficient connection strength between the main body 1 and the robotic arm 2, thereby effectively improving working safety and reliability.

[0029] As an embodiment of the present invention, a handle 6 is provided on the extension portion 22. When the position of the robotic arm 2 needs to be adjusted, the staff pushes the handle 6 inward to reduce the distance between the two load-bearing portions 23 or pulls the handle 6 outward to increase the distance between the two load-bearing portions 23, thereby adjusting the robotic arm 2 according to the required width of the hanging object, thereby improving the convenience and work efficiency of the position adjustment of the robotic arm 2 and effectively reducing the labor intensity of the staff.

[0030] As an embodiment of the present invention, a reinforcement plate 7 is provided on the connecting portion 21. Preferably, the reinforcement plate 7 is welded to the connecting portion 21, which can enhance the overall structural strength of the sling, avoid damage or even falling of the robotic arm 2 due to the excessive weight of the membrane material during the process of transporting the membrane material, and improve the overall work safety and stability.

[0031] As an embodiment of the present invention, there are two lifting rings 5, and each reinforcement plate 7 is provided with a lifting ring 5, that is, the two lifting rings 5 are respectively arranged on the two reinforcement plates 7. Since the part where the reinforcement plate 7 is added is the part with the largest overall structural strength, arranging the lifting ring 5 on the reinforcement plate 7 can enhance the connection strength of the lifting ring 5, and the driving is connected to the lifting ring 5 through the lifting rope, so the entire force of the sling falls on the lifting ring 5. Therefore, the force at the part where the lifting ring 5 is set is most obvious. If the structural strength of the part where the lifting ring 5 is set is not strong enough, the sling will be damaged or broken during the transportation of the membrane material, which poses a safety hazard. Therefore, arranging the lifting ring 5 on the reinforcement plate 7 can improve the overall work safety and stability.

[0032] As an embodiment of the present invention, the positioning hole 3, the positioning groove, and the first latch 4 can adopt the following two structures:

[0033] Structure 1: The robotic arm 2 is provided with a plurality of positioning holes 3 evenly arranged in a straight line. The positioning holes 3 are circular holes.

[0034] Structure 2: A positioning hole 3 is provided on the robotic arm 2, which is a long hole. A positioning slot is provided on the main body 1, which is a long slot. The first latch 4 is a knob latch. The robotic arm 2 is adjusted to the position of the long hole according to specific usage requirements. When it is adjusted to the appropriate position, the knob latch is used to fix the position, thereby fixing the position of the robotic arm 2.

[0035] As an embodiment of the present utility model, a limit slot 8 is provided on the robotic arm 2, and a limit block 9 is provided on the main body 1. The limit block 9 is inserted into the limit slot 8. When the position of the robotic arm 2 is adjusted, the limit block 9 moves in the limit slot 8, and the two ends of the limit slot 8 limit the movement of the limit block 9, thereby limiting the position adjustment of the robotic arm 2.

[0036] As an embodiment of the present invention, a second pin 10 is provided in the limiting groove 8. The second pin 10 can further strengthen the connection strength between the robotic arm 2 and the main body 1, thereby improving the overall stability and reliability. Preferably, the second pin 10 is a knob pin.

[0037] As an embodiment of the present utility model, the covering length of the robotic arm 2 and the main body 1 is H, and the length of the main body 1 is S, satisfying: H≥S / 4, which can ensure the covering length of the robotic arm 2 and the main body 1, improve the connection strength between the robotic arm 2 and the main body 1, avoid the covering length between the two being too short, resulting in separation between the robotic arm 2 and the main body 1 or the robotic arm 2 falling off, and improve the overall working stability and safety.

At the same time, it can also avoid the phenomenon that the robot arm 2 falls off due to insufficient connection strength between the main body 1 and the robot arm 2, thereby effectively improving work safety and reliability; the lifting ring 5 is arranged on the reinforcement plate 7 to enhance the connection strength of the lifting ring 5 and improve the overall work safety and stability; when the position of the robot arm 2 is adjusted, the limit block 9 moves in the limit groove 8, and the two ends of the limit groove 8 limit the movement of the limit block 9, which plays a role in limiting the position adjustment of the robot arm 2.
