[0033] See also Figures 1 to 4 The present embodiment provides a pallet transfer sling, which can adapt to the lifting and transfer of pallets 100 of different sizes, and ensure stability and safety during the lifting process. The pallet transfer sling includes a connecting frame 1, a limiting assembly and a lifting ring 3. The limiting assembly is arranged on the connecting frame 1, and includes two forks 2 that are arranged oppositely and at intervals. The distance between the two forks 2 is adjustable. By adjusting the distance between the two forks 2, the two forks 2 can be inserted into the limiting groove 101 of pallets 100 of different sizes to limit the pallet 100 to the connecting frame 1. The lifting ring 3 is configured to be connected to the lifting equipment, and the installation position of the lifting ring 3 is adjustably arranged on the connecting frame 1. By adjusting the installation position of the lifting ring 3 on the connecting frame 1, the pallet transfer sling can maintain balance during the lifting process.

[0034] See also Figure 4When in use, first fix the goods on the pallet 100, then adjust the distance between the two forks 2 according to the size of the pallet 100, and insert the two forks 2 into the limiting groove 101 of the pallet 100, and adjust the installation position of the lifting ring 3 on the connecting frame 1 according to the size of the pallet 100, and connect the lifting rope of the lifting equipment to the lifting ring 3 for lifting. By adjusting the distance between the two forks 2, pallets 100 of different sizes can be limited on the connecting frame 1, so as to lift and transport pallets 100 of different sizes, and ensure the stability of the limit between the pallet 100 and the connecting frame 1. The center of gravity of pallets 100 of different sizes is different, and the different cargo loaded on the pallet 100 will also affect its center of gravity. Therefore, by adjusting the installation position of the lifting ring 3, the pallet transfer sling can be adapted to the center of gravity of pallets 100 of different sizes, so that it can maintain balance when carrying pallets 100 of different sizes, avoid tilting during the lifting process, and ensure stability and safety during lifting.

[0035] Optionally, see Figure 1 and Figure 3 The connecting frame 1 includes a first connecting arm 11 and a second connecting arm 12 connected at an angle. The first connecting arm 11 is arranged parallel to the fork 2. The two forks 2 are arranged on both sides of the first connecting arm 11. The first connecting arm 11 is provided with a plurality of limiting holes 111 along its extension direction. The adjacent limiting holes 111 are connected. The lifting ring 3 can be hooked in any limiting hole 111. In this way, the installation position of the lifting ring 3 on the connecting frame 1 can be adjusted by hooking the lifting ring 3 in the limiting holes 111 at different positions, and the adjustment is very convenient. Specifically, for the convenience of description, the extension direction of the fork 2 is defined as the first direction, and the direction perpendicular to the extension direction of the fork 2 is defined as the second direction. By adjusting the distance between the two forks 2, the fork 2 can be inserted into the limiting groove 101 of the pallet 100, thereby ensuring the stability of the pallet 100 in the second direction; by hooking the lifting ring 3 in different limiting holes 111, the position of the lifting ring 3 in the first direction can be adjusted, thereby ensuring the stability of the pallet 100 in the first direction, and then ensuring the stability during the lifting process. In this embodiment, the first connecting arm 11 and the second connecting arm 12 are vertically connected to ensure the structural stability of the connecting frame 1 .

[0036] Optionally, the fork 2 includes a connected load-bearing portion 21 and a connecting portion 22, the load-bearing portion 21 can be inserted into the limiting groove 101, and the connecting portion 22 is slidably connected to the connecting frame 1. This arrangement realizes the sliding connection between the fork 2 and the connecting frame 1, and the distance between the two forks 2 can be adjusted by sliding any fork 2, which is very convenient to use.

[0037] Furthermore, a guide rod 13 is provided on the connecting frame 1, and the guide rod 13 extends along the sliding direction of the fork 2, and the connecting portion 22 is slidably connected to the guide rod 13. The guide rod 13 can provide a guide for the fork 2 to ensure the stability of the fork 2 when it moves. In this embodiment, the guide rod 13 is connected to the end of the second connecting arm 12 away from the first connecting arm 11.

[0038] Preferably, see Figure 2 , both ends of the guide rod 13 are provided with a stopper 133, and the stopper 133 can limit the fork 2 to the guide rod 13. The stopper 133 can limit the movement stroke of the fork 2 to prevent the fork 2 from escaping from the guide rod 13. In this embodiment, the stopper 133 is a baffle plate provided at the end of the guide rod 13. Optionally, the stopper 133 and the guide rod 13 are integrally formed.

[0039] Furthermore, the connecting portion 22 includes an arcuate connecting portion 221 and two vertical connecting portions 222. The two vertical connecting portions 222 are relatively arranged at the two ends of the arcuate connecting portion 221, and one of the vertical connecting portions 222 is connected to the bearing portion 21. The top surface of the guide rod 13 is provided with an arcuate guide surface 131 along its extension direction, and the opposite sides of the guide rod 13 are provided with vertical guide surfaces 132 tangent to the arcuate guide surface 131. The arcuate connecting portion 221 can slide with the arcuate guide surface 131, and the vertical connecting portion 222 can slide with the vertical guide surface 132. The arc-shaped connecting portion 221 cooperates with the arc-shaped guide surface 131, and the vertical connecting portion 222 cooperates with the vertical guide surface 132, so that the fork 2 can slide stably along the guide rod 13. At the same time, when the pallet 100 is limited on the connecting frame 1, under the action of the gravity of the pallet 100, the two vertical connecting portions 222 and the two vertical guide surfaces 132 can fit tightly, thereby preventing the connecting portion 22 from being separated from the guide rod 13. In addition, such a setting also realizes a detachable connection between the fork 2 and the guide rod 13, so that the forks 2 of different lengths can be replaced to adapt to pallets 100 of different sizes. Specifically, when replacing the fork 2, refer to Figure 3 The original fork 2 can be removed from the guide rod 13 by moving it from bottom to top; the connecting portion 22 of the new fork 2 is opposite to the guide rod 13, and the connecting portion 22 is hooked on the guide rod 13 from top to bottom, which is very convenient for installation and disassembly.

[0040] Optionally, the length of the bearing portion 21 is not less than 1 / 2 of the length of the pallet 100 to ensure stability when the pallet 100 is hoisted.

[0041] Optionally, a side of the guide rod 13 facing the connecting portion 22 is provided with an anti-skid protrusion. The anti-skid protrusion can increase the friction between the connecting portion 22 and the guide rod 13, and prevent the connecting portion 22 from being separated from the guide rod 13.

[0042] Preferably, see Figure 3The top surface of the bearing portion 21 is tilted downward from one end connected to the connecting portion 22 to the other end. Such a configuration forms a guiding inclined surface on the top surface of the bearing portion 21, which facilitates the bearing portion 21 to be inserted into the limiting groove 101 of the tray 100.

[0043] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
