[0042] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be arbitrarily combined with each other.

[0043] The present application provides an inner-support type lifting tool, including a bracket, a tightening mechanism, a lifting mechanism and a reset structure. By the lifting mechanism moving upward on the bracket, the tightening mechanism is inserted into the inner circle of the material; under the action of the self-weight of the material, the lifting mechanism moves downward on the bracket, and the tightening mechanism can support the inner circle of the material to clamp the material; by the lifting mechanism moving upward on the bracket again, when the lifting mechanism moves to the reset mechanism, the reset mechanism restricts the lifting mechanism from moving downward, so that the tightening mechanism releases the material. The inner-support type lifting tool of the present application can clamp and fix tubular parts or materials, and use the self-weight of the tubular parts or materials to fix them on the lifting tool, which can maintain a good clamping force. Moreover, the lifting tool of the present application has a simple structure and is suitable for loading and unloading with a manipulator.

[0044] Some of the specific implementation manners described below are intended to facilitate the understanding of those skilled in the art of the present embodiment, and the present embodiment is not limited to some of the specific implementation manners described below.

[0045] Such as Figure 1As shown in the figure, an exemplary embodiment of the present application provides an inner support type lifting tool, which includes a bracket 1, a tightening mechanism 2, a lifting mechanism 3 and a reset mechanism 4. The first end of the tightening mechanism 2 is rotatably connected to the first end of the bracket 1, and the tightening mechanism 2 can be inserted into the inner circle of the material; the first end of the lifting mechanism 3 is rotatably connected to the second end of the tightening mechanism 2, and the second end of the lifting mechanism 3 is slidably connected to the bracket 1; the lifting mechanism 3 is used to move up and down on the bracket 1 to clamp or release the material by the tightening mechanism 2; the first end of the reset mechanism 4 is rotatably connected to the second end of the bracket 1, and the second end of the reset mechanism 4 can limit the downward movement of the lifting mechanism 3 so that the tightening mechanism 2 releases the material.

[0046] In this embodiment, by the upward movement of the lifting mechanism 3 on the bracket 1, the tightening mechanism 2 is inserted into the inner circle of the material; under the action of the self-gravity of the material, the lifting mechanism 3 moves downward on the bracket 1, and the tightening mechanism 2 can support the inner circle of the material to clamp the material; by the upward movement of the lifting mechanism 3 on the bracket 1 again, when the lifting mechanism 3 moves to the reset mechanism 4, the reset mechanism 4 restricts the downward movement of the lifting mechanism 3 so that the tightening mechanism 2 releases the material. The inner support type lifting tool of this embodiment can clamp and fix tubular parts or materials, and use the self-weight of the tubular parts or materials to fix them on the lifting tool, and can maintain a good clamping force. Among them, the tubular material is, for example, a paper tube.

[0047] In one embodiment, the bracket 1 includes a base 11 and two oppositely arranged support plates 12. One end of the support plate 12 is fixedly connected to the base 11, and the other end of the support plate 12 is rotatably connected to the tightening mechanism 2; there is a space for accommodating the lifting mechanism 3 between the two support plates 12.

[0048] In this embodiment, the base 11 can play a role in fixing the support plate 12, and the support plate 12 can play a role in supporting the tightening mechanism 2, the lifting mechanism 3 and the reset mechanism 4. Among them, fixing holes 111 can be provided on the base 11, and through the cooperation of the fixing holes 111 and bolts and nuts, the lifting tool is fixed at the position to be suspended.

[0049] In one embodiment, as Figure 1 and Figure 2 shown, the lifting mechanism 3 includes a limiting rod 31 and two oppositely arranged lifting rods 32; one end of the lifting rod 32 is slidably connected to the bracket 1, and the other end of the lifting rod 32 is rotatably connected to the tightening mechanism 2; the limiting rod 31 intersects with the lifting rod 32, and the limiting rod 31 is located at one end of the lifting rod 32 close to the tightening mechanism 2 for blocking the material. Among them, one end of the lifting rod 32 is slidably connected to the support plate 12.

[0050] In this embodiment, after the tightening mechanism 2 is inserted into the inner circle of the material, the material is moved upward, and the material pushes the limiting rod 31 upward, thereby driving the lifting rod 32 connected to the limiting rod 31 to move upward. Among them, in order to be able to block the material, the length of the limiting rod 31 needs to be greater than the inner diameter of the material, and the limiting rod 31 and the lifting rod 32 can be perpendicular to each other.

[0051] In one embodiment, as Figures 1-3 shown, the lifting mechanism 3 includes a limiting rod 31, two oppositely arranged lifting rods 32, at least one first hook body 33, a moving block 34, and at least one second hook body 35. Among them, the structures of the limiting rod 31 and the lifting rod 32 are the same as those in the above embodiment and will not be described in detail here. At least one first hook body 33 is arranged at one end of the lifting rod 32 close to the reset mechanism 4; the moving block 34 is slidably connected to the lifting rod 32 and is located between the first hook body 33 and the limiting rod 31; at least one second hook body 35 is arranged at one end of the moving block 34 close to the first hook body 33;

[0052] The reset mechanism 4 includes at least one reset hook 41. The reset hook 41 includes a reset hook body 411 and a third hook body 412. One end of the reset hook body 411 is rotatably connected to the second end of the bracket 1; the third hook body 412 is arranged at the other end of the reset hook body 411 and faces the bracket 1. When the lifting mechanism 3 moves upward, the first hook body 33 and the second hook body 35 can move above the third hook body 412, and the third hook body 412 abuts against the second hook body 35 to pre-clamp the material by the tightening mechanism 2; when the lifting mechanism 3 moves downward, the second hook body 35 is separated from the third hook body 412, the first hook body 33 and the second hook body 35 move below the third hook body 412, and the third hook body 412 abuts against the first hook body 33, and the tightening mechanism 2 tightens the material.

[0053] In this embodiment, the sling is initially in a relaxed state, as Figure 4As shown in the figure. The material is sleeved on the tightening mechanism 2 from bottom to top, and then the material is pushed upward. The material pushes the limit rod 31 upward. The limit rod 31 drives the lifting rod 32 to move upward. The moving block 34 moves upward together with the lifting rod 32. During the upward movement of the moving block 34, the first hook body 33 and the second hook body 35 will push the third hook body 412 to move away from the support plate 12, that is, the third hook body 412 is opened until the first hook body 33 and the second hook body 35 move above the third hook body 412. At this time, the material is slowly lowered. Since the reset hook 41 has a certain gravity, it will be converted into a clamping force. The third hook body 412 can hook on the inclined surface of the second hook body 35 to make the moving block 34 temporarily stationary, and the tightening mechanism 2 pre-clamps the material. After a certain period of time, under the action of the gravity of the material, the material will drive the lifting rod 32 to move downward during the downward movement. Until the horizontal plane of the first hook body 33 fits with the horizontal plane of the second hook body 35, it will drive the moving block 34 to move downward together. At this time, the inclined surface of the second hook body 35 will push the third hook body 412 to move away from the support plate 12 again to open the reset hook 41. The second hook body 35 and the first hook body 33 move below the third hook body 412, and the third hook body 412 abuts against the first hook body 33, and the tightening mechanism 2 tightens the material, as Figure 5 shown in the tightened state.

[0054] When unloading the material, the material is moved upward. The material pushes the limit rod 31 upward. When the limit rod 31 drives the lifting rod 32 to move upward and the first hook body 33 moves above the third hook body 412, the third hook body 412 can hook the first hook body 33. At this time, the tightening mechanism 2 contracts and the material can be removed. The spreader forms a Figure 4 relaxed state as shown in the figure.

[0055] Among them, there are two first hook bodies 33 and two second hook bodies 35. Along the length direction of the support plate 12, the two first hook bodies 33 are respectively located on both sides of the support plate 12 and are symmetrically arranged. The two second hook bodies 35 are respectively located on both sides of the support plate 12 and are symmetrically arranged. The first hook body 33 and the second hook body 35 are both arranged in a direction away from the support plate 12. There are two reset hooks 41. Along the length direction of the support plate 12, the two reset hooks 41 are respectively located on both sides of the support plate 12 and are symmetrically arranged; one end of the reset hook body 411 is rotatably connected to one end of the support plate 12, and the third hook body 412 is arranged facing the support plate 12.

[0056] In an embodiment, the first hook body 33 and the second hook body 35 are symmetrically arranged in the horizontal direction.

[0057] In this embodiment, the first hook body 33 and the second hook body 35 are symmetrically arranged. Along the horizontal direction close to the support plate 12, the inclined surface of the first hook body 33 is inclined upward, the inclined surface of the second hook body 35 is inclined downward, and the inclined surface of the third hook body 412 is inclined upward. Such an arrangement can facilitate the mutual cooperation of the first hook body 33, the second hook body 35, and the third hook body 412 to clamp or release the material.

[0058] In one embodiment, as Figure 2 and Figure 3 shown, a groove 341 is provided on the moving block 34, and a cavity 36 is provided between the two lifting rods 32. The moving block 34 makes a lifting motion in the cavity 36 through the groove 341.

[0059] In this embodiment, through the cooperation of the groove 341 on the moving block 34 and the cavity 36 between the lifting rods 32, the moving block 34 makes a lifting motion in the cavity 36 to improve the stability of the movement of the moving block 34.

[0060] In one embodiment, as Figure 1 shown, the reset hook body 411 is connected to the bracket 1 through a hinge 5.

[0061] In this embodiment, the reset hook body 411 is connected to the bracket 1 through the hinge 5, which can improve the stability of the connection between the two. Among them, the reset hook body 411 can be connected to the support plate 12 through the hinge 5.

[0062] In one embodiment, as Figure 1 and Figure 2 shown, a pin shaft 37 is provided at one end of the lifting mechanism 3 close to the reset mechanism 4, and a strip-shaped groove 121 is provided at one end of the bracket 1 close to the reset mechanism 4. The pin shaft 37 makes a lifting motion in the strip-shaped groove 121.

[0063] In this embodiment, the lifting mechanism 3 makes a lifting motion in the strip-shaped groove 121 of the bracket 1 through the pin shaft 37, which can improve the stability of its movement. Among them, the pin shaft 37 can be provided at one end of the lifting rod 32 close to the reset mechanism 4, and the strip-shaped groove 121 is provided at one end of the support plate 12 close to the reset mechanism 4.

[0064] In one embodiment, the tightening mechanism 2 includes at least one support hook 21 and at least one connecting rod 22. One end of the support hook 21 is rotatably connected to the bracket 1; one end of the connecting rod 22 is rotatably connected to the other end of the support hook 21, and the other end of the connecting rod 22 is rotatably connected to the lifting mechanism 3.

[0065] In this embodiment, through the arrangement of the support hook 21 and the connecting rod 22, the opening angle of the support hook 21 can be adjusted so that the support hook 21 can be opened to abut against the inner wall of the material to clamp the material.

[0066] One end of the bracing hook 21 is rotatably connected to the support plate 12, one end of the connecting rod 22 is rotatably connected to the other end of the bracing hook 21, and the other end of the connecting rod 22 is rotatably connected to the lifting rod 32. The number of the bracing hooks 21 can be, for example, two, and the number of the connecting rods 22 can be four. Along the length direction of the support plate 12, the two bracing hooks 21 are respectively located on both sides of the support plate 12 and are symmetrically arranged. A connecting rod 22 is arranged on both sides of each bracing hook 21, which can improve the stability of the bracing hook 21.

[0067] In one embodiment, the end of the hook 21 facing away from the bracket 1 is in a needle-point structure.

[0068] In this embodiment, the end of the support hook 21 facing away from the bracket 1 is arranged in a needle-point shape, which can be easily inserted into the inner wall of the material to clamp and fix the material.

[0069] An exemplary embodiment of the present application provides a working principle of an internally supported hanger, wherein the material of this embodiment is described using a paper tube as an example.

[0070] Put the paper tube into the support hook 21 from bottom to top, and then push the paper tube upward. The paper tube pushes the limit rod 31 upward, and the limit rod 31 drives the lifting rod 32 to move upward. The moving block 34 moves upward with the lifting rod 32. During the upward movement of the moving block 34, the first hook body 33 and the second hook body 35 will push the third hook body 412 to move away from the support plate 12, that is, the third hook body 412 is supported until the first hook body 33 and the second hook body 35 move to the top of the third hook body 412. At this time, slowly put the paper tube downward. Since the reset hook 41 has a certain gravity, it will be converted into a clamping force. The third hook body 412 can be hooked on the inclined surface of the second hook body 35 to temporarily stop the moving block 34, and the support hook 21 pre-clamps the paper tube. After a certain period of time, under the action of the gravity of the paper tube, the paper tube will move downward and drive the lifting rod 32 to move downward until the horizontal plane of the first hook body 33 is in contact with the horizontal plane of the second hook body 35, and then drive the moving block 34 to move downward together. At this time, the inclined surface of the second hook body 35 will push the third hook body 412 to move away from the support plate 12 again to open the reset hook 41, and the second hook body 35 and the first hook body 33 move to the bottom of the third hook body 412, and the third hook body 412 is in contact with the first hook body 33, and the tightening mechanism 2 tightens the material. Figure 5 Shown in the tightened state.

[0071] When unloading the paper tube, the paper tube is moved upward, and the paper tube pushes the limit rod 31 upward. The limit rod 31 drives the lifting rod 32 to move upward. When the first hook body 33 moves to the top of the third hook body 412, the third hook body 412 can hook the first hook body 33. At this time, the support hook 21 contracts and the paper tube can be removed. The sling is formed as shown in the figure. Figure 4 Relaxed state shown.

[0072] In summary, the spreader of the present application utilizes the self - gravity of the paper tube for tightening, so that the tightening degrees of the paper tubes in the same batch are kept consistent. The spreader hook 21 can effectively hang the paper tube without causing deformation damage to the paper tube. The inner - support type spreader can make the position of the paper tube relatively fixed. By only setting an appropriate up - and - down movement distance, it is applicable to the manipulator for loading and unloading, greatly improving the consistency and efficiency of processing.
