[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] The present application embodiment discloses an automatic hanging device. Figures 1 to 4 , which includes a main shaft 1, a group of wire rope wheels 11 are rotatably arranged at the top of the main shaft 1, and the wire rope of the crane is wound around the wire rope wheels 11. An outer shell 2 and an inner shell 3 are sleeved on the main shaft 1, and both the outer shell 2 and the inner shell 3 are slidably connected with the main shaft 1. The inner shell 3 is located inside the outer shell 2, and a bearing 31 is installed between the outer shell 2 and the inner shell 3, so that the outer shell 2 and the inner shell 3 are rotatably connected. Three through slots 21 are penetrated through the side wall of the outer shell 2, and the through slots 21 penetrate the bottom wall of the outer shell 2. The spacing between adjacent through slots 21 is equal, and the claws 4 are rotatably installed in the through slots 21. An opening and closing component 5 is installed on the outer wall of the inner shell 3, and the opening and closing component 5 is used to control the opening and closing of the claws 4. A driving component 6 is installed in the inner shell 3, and the driving component 6 is connected to the bottom wall of the main shaft 1. The driving component 6 is used to drive the outer shell 2 and the inner shell 3 to rotate relative to each other. When the crane drives the outer shell 2 to fall onto the material container, the main shaft 1 continues to fall, and at this time, the main shaft 1 and the inner shell 3 move relative to each other. Then the main shaft 1 causes the driving component 6 to control the outer shell 2 and the inner shell 3 to rotate relative to each other, and the outer shell 2 and the inner shell 3 rotate relative to each other to drive the opening and closing component 5, and the opening and closing component 5 opens the hanging claw 4. When the crane drives the main shaft 1 to rise, the main shaft 1 first moves relative to the inner shell 3, and then the driving component 6 controls the outer shell 2 and the inner shell 3 to rotate relative to each other, and the outer shell 2 and the inner shell 3 rotate relative to each other to drive the opening and closing component 5, and the opening and closing component 5 closes the hanging claw 4, and then the hanging claw 4 is hung on the material container. Then the main shaft 1 continues to rise, driving the inner shell 3 and the outer shell 2 to rise, and the outer shell 2 drives the material container connected by the hanging claw 4 to rise. While reducing the use of electrical equipment, the sling automatically hangs the material container, achieving the effect of facilitating the automatic hanging of the material container by the sling, and reducing the cost of the sling.

[0034] In order to control the opening and closing of the claw 4, refer to Figures 1 to 3The hanging claw 4 includes a hanging arm 41 and a hook claw 42. The side wall of the hanging arm 41 is rotatably connected to the inner wall of the through slot 21. The bottom end of the hanging arm 41 is integrally formed with the hook claw 42. The hook claw 42 is convenient for hooking with the material container. The opening and closing assembly 5 includes a plurality of abutment wheels 51. The abutment wheels 51 are rotatably connected to the inner shell 3. The abutment wheels 51 abut against the side wall of the hanging arm 41. When the inner shell 3 and the outer shell 2 rotate relative to each other, the inner shell 3 drives the abutment wheels 51 to rotate, and the abutment wheels 51 move along the side wall of the hanging arm 41, and then the abutment wheels 51 cause the hanging arm 41 to rotate.

[0035] In order to drive the inner housing 3 and the outer housing 2 to rotate relative to each other, Figures 1 to 5 , a connecting seat 9 is sleeved on the main shaft 1, the connecting seat 9 is welded to the main shaft 1, and the connecting seat 9 is located between the rope pulley seat and the outer shell 2. A plurality of guide holes 91 are provided on the bottom wall of the connecting seat 9. A guide column 22 is inserted into the guide hole 91, and the bottom wall of the guide column 22 is welded to the top wall of the outer shell 2. The driving assembly 6 includes a plurality of driving columns 61 and a driving seat 62. The driving seat 62 is installed on the bottom wall of the main shaft 1, and the driving seat 62 is movably arranged in the inner shell 3, and the steps arranged on the inner wall of the inner shell 3 make it difficult for the driving seat 62 to move out of the inner shell 3. A plurality of driving grooves 7 are provided on the side wall of the driving seat 62, and adjacent driving grooves 7 are connected to each other. One end of the driving column 61 is inserted into the driving groove 7, and the driving column 61 is slidably connected to the driving groove 7, and the other end of the driving column 61 is connected to the inner wall of the inner shell 3. The driving groove 7 includes an upper groove 71, a lower groove 72 and an inclined groove 73. The bottom end of the upper groove 71 is connected to one end of the inclined groove 73, and the other end of the inclined groove 73 is connected to the top of the lower groove 72. The adjacent upper grooves 71 and lower grooves 72 are connected to each other. When the guide post 22 is inserted into the guide hole 91, the main shaft 1 and the outer shell 2 are not easy to rotate relative to each other. Then, when the guide post 22 is inserted into the guide hole 91, and the main shaft 1 and the inner shell 3 are away from each other, the driving post 61 located in the upper groove 71 moves along the inclined groove 73 to the lower groove 72. When the guide post 22 is inserted into the guide hole 91, and the main shaft 1 and the inner shell 3 are close to each other, the driving post 61 located in the lower groove 72 moves along the inclined groove 73 to the upper groove 71. During the movement of the driving post 61, the driving post 61 drives the inner shell 3 and the outer shell 2 to rotate relative to each other.

[0036] refer to Figure 3 and Figure 4 , a limiting hole 81 is formed through the side wall of the inner shell 3, and a limiting sleeve 8 is installed in the limiting hole 81. The end of the driving column 61 away from the main shaft 1 is inserted into the limiting sleeve 8, and a limiting block 82 is installed on the end of the limiting sleeve 8 away from the main shaft 1. One side of the limiting block 82 is in contact with the outer wall of the inner shell 3, and the other side of the limiting block 82 is used to abut against the hanging arm 41. The limiting block 82 is installed between the hanging arm 41 and the inner shell 3, so that the hanging arm 41 is not easy to rotate toward the inner shell 3. In addition, the hanging arm 41 limits the displacement of the abutting wheel 51 in the circumferential direction, and limits the distance of relative rotation between the inner shell 3 and the outer shell 2.

[0037] In order to achieve the situation of protecting the hanging claw 4, refer to Figure 1 and Figure 3 A protective shell 92 is installed on the connecting seat 9, and the protective shell 92 is arranged outside the outer shell 2 and the hanging claw 4. The collision between the outer shell 2 and the hanging claw 4 is reduced.

[0038] The implementation principle of an automatic hanging device in the embodiment of the present application is as follows: when the crane drives the outer shell 2 to fall onto the material container, the main shaft 1 continues to fall, and the wire rope wheel 11 gradually approaches the outer shell 2. When the guide column 22 on the outer shell 2 is inserted into the guide hole 91 of the connecting seat 9, the main shaft 1 and the outer shell 2 are not easy to rotate relative to each other. At this time, the main shaft 1 continues to fall, and the driving column 61 located in the lower groove 72 moves along the inclined groove 73 to the upper groove 71, and the driving column 61 drives the inner shell 3 and the outer shell 2 to rotate relative to each other. Then the inner shell 3 drives the abutment wheel 51 to move along the side wall of the hanging arm 41, and abuts the hanging claw 4 until it opens. When the guide column 22 is inserted into the guide hole 91 and the wire rope wheel 11 gradually moves away from the outer shell 2, the driving column 61 located in the upper groove 71 moves along the inclined groove 73 to the lower groove 72, and the driving column 61 drives the inner shell 3 and the outer shell 2 to rotate relative to each other. Then the inner housing 3 drives the abutting wheel 51 to move along the side wall of the hanging arm 41, abuts the hanging claw 4 until it is closed, and then the hanging claw 4 is hung on the material container. Then the crane drives the main shaft 1 to continue to rise, the main shaft 1 drives the inner housing 3 and the outer housing 2 to rise, and the outer housing 2 drives the material container connected by the hanging claw 4 to rise. Through the above method, while reducing the use of electrical equipment, the sling automatically hangs the material container, achieving the effect of facilitating the automatic hanging of the material container by the sling, and reducing the cost of the sling.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
