[0038] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0039] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0040] Please see Figures 1 to 5 A self-unloading hoisting clamp for a reel provided in one embodiment of the present invention includes an upper inner support hoist 11 and a lower inner support hoist 12, wherein the outer diameter of the lower inner support hoist 12 is smaller than the outer diameter of the upper inner support hoist 11;

[0041] The upper inner support hanger 11 includes an upper housing 111, an upper shaft 112 disposed inside the upper housing 111, and an upper support block 113 embedded in the outer wall of the upper housing 111;

[0042] The lower inner support hanger 12 includes a lower housing 121, a lower shaft 122 disposed inside the lower housing 121, and a lower support block 123 embedded in the outer wall of the lower housing 121.

[0043] The upper shaft 112 and the lower shaft 122 are connected by an intermittent guide element 13, and an intermittent guide slide is provided around the outer wall of the intermittent guide element 13;

[0044] The top of the lower housing 121 is fixedly connected to the bottom of the upper housing 111. Two guide posts 14 are symmetrically provided on the top of the lower housing 121, and the inner ends of the two guide posts 14 are located in the intermittent guide slide.

[0045] The upper shaft 112 passes through the top of the upper inner support hanger 11 and is connected to a lifting ring 15. When the lifting ring 15 drives the upper shaft 112, the intermittent guide element 13 and the lower shaft 122 to move up and down, the two guide columns 14 slide synchronously in the intermittent guide slide in a counterclockwise direction and have the same movement trajectory.

[0046] It should be noted that, in this utility model, during hoisting operations, the hoisting clamp is placed inside the drum, and the crane hooks the lifting ring 15. When the lifting ring 15 drives the upper shaft 112, the intermittent guide element 13, and the lower shaft 122 to move upward, the two guide columns 14 simultaneously slide downward in the intermittent guide slide in a counterclockwise direction. The upper shaft 112 opens the upper support block 113, and the lower shaft 122 opens the lower support block 123, thereby hoisting the drum.

[0047] Once the drum is transported to the target position, the lifting ring 15 is released. Since the top of the lifting clamp is on the drum, under its own weight, the lifting ring 15, the upper shaft 112, the intermittent guide element 13, and the lower shaft 122 move downwards. The two guide columns 14 simultaneously slide upwards in the intermittent guide slide in a counterclockwise direction. The upper support block 113 retracts, and the lower support block 123 retracts, thereby unloading the drum. The entire process requires no additional power, which reduces costs.

[0048] Specifically, the lower inner support lifting device 12 is used to lift small-sized (e.g., 3-inch, or other sizes) drums, and the upper inner support lifting device 11 is used to lift large-sized (e.g., 6-inch, or other sizes) drums. When lifting small-sized drums, the lower inner support lifting device 12 is inserted into the corresponding drum; when lifting large-sized drums, the upper inner support lifting device 11 is inserted into the corresponding drum.

[0049] Please see Figures 2 to 5 The intermittent guide slide includes two sets of guide slides that are connected to each other. Each set of guide slides includes a first slide 131 and a second slide 132 that are connected to each other. The first slide 131 is located on the right side.

[0050] In a set of guide slides, the lower right side of the first slide 131 is connected to the upper left side of the second slide 132 in another set of guide slides, and the lower left side of the first slide 131 is connected to the upper right side of the second slide 132 in the same set.

[0051] The upper left side of the second slide 132 in this group is connected to the lower right side of the first slide 131 in another group of guide slides;

[0052] One guide post 14 is located in a set of guide tracks.

[0053] It should be noted that when the guide column 14 is located at the bottom of the first slide rail 131, the upper shaft 112 opens the upper support block 113 and the lower shaft 122 opens the lower support block 123, thereby hoisting the drum.

[0054] After the drum is transported to the target position, the lifting ring 15 is released. Under its own weight, the lifting ring 15, the upper shaft 112, the intermittent guide element 13 and the lower shaft 122 move downwards, and the guide column 14 slides upwards to the top of the first slide rail 131. The upper support block 113 retracts and the lower support block 123 retracts, thereby unloading the drum.

[0055] When the lifting ring 15 drives the upper shaft 112, the intermittent guide element 13 and the lower shaft 122 to move upward again, the guide column 14 slides downward to the bottom of the second slide rail 132, the upper support block 113 opens, the lower support block 123 opens, thereby hoisting the drum;

[0056] After the drum is transported to another target location, the lifting ring 15 is released. Under its own weight, the lifting ring 15, the upper shaft 112, the intermittent guide element 13 and the lower shaft 122 move downwards, and the guide column 14 slides upwards to the top of the second slide rail 132. The upper support block 113 retracts and the lower support block 123 retracts, thereby unloading the drum.

[0057] When the lifting ring 15 drives the upper shaft 112, the intermittent guide element 13 and the lower shaft 122 to move upward again, the guide column 14 slides downward to the bottom of the first slide rail 131, the upper support block 113 opens, the lower support block 123 opens, thereby hoisting the drum;

[0058] Following the above trajectory, the guide column 14 slides in a cyclical manner.

[0059] Please see Figures 2 to 5 The first slide rail 131 includes a first upper opening 1311 and a first lower opening 1312 arranged opposite to each other, with the top of the first upper opening 1311 located to the left of the bottom of the first lower opening 1312.

[0060] The left walls of the first upper opening 1311 and the first lower opening 1312 are both vertical, and the misalignment is connected to the right side of the second slide rail 132. This means that when the guide post 14 slides upward, it can only enter the top of the first slide rail 131 to the left, and when it slides downward, it can only enter the bottom of the second slide rail 132.

[0061] Please see Figures 2 to 5The second slide 132 includes a second upper opening 1321 and a second lower opening 1322 arranged opposite to each other, with the top of the second upper opening 1321 located to the left of the second lower opening 1322.

[0062] The left wall of the second upper opening 1321 and the left wall of the second lower opening 1322 are both vertical, and the misalignment is connected to the right side of the first slide 131 in another set of guide slides. This means that when the guide column 14 slides upward, it can only enter the top of the second slide 132 to the left, and when it slides downward, it can only enter the bottom of the first slide 131 in another set of guide slides.

[0063] Please see Figures 1 to 3 The lower housing 121 includes a lower hollow cylinder 1211 and a bottom cover 1212 connected to the lower hollow cylinder 1211 by bolts;

[0064] A connecting ring 1213 is provided on the outer wall of the lower hollow cylinder 1211, and the connecting ring 1213 is connected to the bottom of the upper shell 111 by bolts;

[0065] Two guide posts 14 are symmetrically installed on the side wall of the lower hollow cylinder 1211, and the guide posts 14 are located above the connecting ring 1213.

[0066] Specifically, the lower hollow cylinder 1211 has a lower vertical groove 1214 on its outer wall, and the lower support block 123 is located in the lower vertical groove 1214 so that the lower support block 123 can be opened or closed by the lower shaft 122.

[0067] Please see Figure 2 and Figure 3 The lower support block 123 has a first inner stop block 1231 on the inner side of its top and a first outer stop block 1232 on the outer side of its bottom.

[0068] The first inner stop block 1231 is located inside the lower hollow cylinder 1211, and the first outer stop block 1232 is located outside the lower hollow cylinder 1211, to prevent the lower support block 123 from falling out of the lower vertical groove 1214.

[0069] Please see Figures 1 to 3 The upper housing 111 includes an upper hollow cylinder 1111 and a top cover 1112 connected to the upper hollow cylinder 1111 by bolts. The upper shaft 112 passes through the top cover 1112 and is connected to the lifting ring 15.

[0070] Specifically, the upper hollow cylinder 1111 has an upper vertical groove 1113 on its outer wall, and the upper support block 113 is located in the upper vertical groove 1113 so that the upper support block 113 can be opened or closed by the upper shaft 112.

[0071] Please see Figure 2 and Figure 3 In a preferred embodiment of the present invention, the upper support block 113 is provided with a second inner block 1131 on the inner side of the top and a second outer block 1132 on the outer side of the bottom.

[0072] The second inner stop 1131 is located inside the upper hollow cylinder 1111, and the second outer stop 1132 is located outside the upper hollow cylinder 1111, to prevent the upper support block 113 from falling out of the upper vertical groove 1113.

[0073] In summary, this utility model combines upper inner support lifting devices 11 and lower inner support lifting devices 12 of different specifications through intermittent guide element 13, which can lift drums of different specifications without changing the lifting devices, thereby improving efficiency; at the same time, the whole process does not require additional power, thus reducing costs.
