[0021] like Figures 1-6 As shown, this utility model discloses a lifting device for loading and unloading ton bags, comprising a hook body 1. The hook body 1 includes a top plate 101 and side suspension plates 102. Two side suspension plates 102 are provided, and the two side suspension plates 102 are respectively fixedly connected to the left and right side walls of the top plate 101. The two side suspension plates 102 are symmetrical about the center of the width direction of the top plate 101. The lower parts of the two side suspension plates 102 extend out of the top plate 101, and the length of the two side suspension plates 102 is the same as the length of the top plate 101. Multiple grooves 103 are formed on the bottom surface of each side suspension plate 102. The multiple grooves 103 are linearly and evenly distributed along the length direction of the side suspension plate 102. The distance between two adjacent grooves 103 on each side suspension plate 102 is equal to the length of the ton bag. Rotatable connections are provided within each groove 103. There is a hook 3, and the distance between the hooks 3 connected to the two side suspension plates 102 is equal to the width of the ton bag; each side suspension plate 102 is provided with a through hole 104, which is set along the length of the side suspension plate 102 and penetrates through the side suspension plate 102. The through hole 104 penetrates multiple grooves 103 and is connected to a connecting rod 4 in the through hole 104. The hook 3 includes a connecting pipe 301 and a hook body 302. The hook body 302 is fixedly connected to the outer wall of the connecting pipe 301. Each connecting pipe 301 is rotatably connected to a connecting rod 4 in a groove 103. Two lifting rings 2 are fixedly connected to the top surface of the top plate 101. The two lifting rings 2 are respectively connected to the front and rear ends of the top surface of the top plate 101. The two lifting rings 2 are symmetrically arranged with respect to the center of the length of the top plate 101.

[0022] In this embodiment, each side suspension plate 102 has six grooves 103, so the hook body 1 is connected to a total of six hooks 3. This utility model can connect twelve ton bags at a time. If the existing technology is used to lift twelve ton bags, the twelve ton bags are connected to a main hook by slings. After being lifted, the twelve ton bags will be squeezed together towards the center position below the main hook. When loading or unloading, the ton bags need to be evenly distributed. Therefore, it is necessary to manually place the twelve ton bags when they are unhooked or to use an overhead crane or gantry crane to lift and adjust their positions multiple times. In this utility model, since the distance between two adjacent grooves 103 on each side suspension plate 102 is equal to the length of the ton bag, and the distance between the hooks 3 connected to the two side suspension plates 102 is also equal to the length of the ton bag, the distance between the grooves 103 on each side suspension plate 102 is equal to the length of the ton bag. The spacing is equal to the width of the ton bags, so the twelve ton bags connected by this utility model are evenly distributed. In this embodiment, the twelve ton bags are evenly distributed in two rows of six. The hook body 1 is connected to the main hook of the overhead crane or gantry crane through two lifting rings 2. When in use, the main hook and the two lifting rings 2 are connected by a lifting rope or sling to ensure that the hook body 1 is evenly and horizontally lifted. After the hook body 1 is lifted, the even distribution of the twelve ton bags will not be disrupted. Therefore, when loading or unloading, there is no need to manually adjust the position of the ton bags, nor is it necessary to use an overhead crane or gantry crane to lift and adjust the position multiple times. It is only necessary to remove multiple ton bags from the hook body 302, which improves the efficiency of loading and unloading ton bag materials, reduces the intensity of manual labor, and effectively protects the safety of operators.

[0023] The distance and spacing between the groove 103 and the hook 3 can be reasonably designed according to the number of ton bags to be lifted at one time and the specific size of the ton bags, and it does not necessarily have to be in the 2×6 manner described in this embodiment.

[0024] Since the specifications of ton bags are generally fixed and do not change, this utility model can be reused after determining the spacing of the grooves 103 and the hooks 3 according to the length and width of the ton bag, without the need for adjustment or remanufacturing each time.

[0025] The connecting rod 4 includes a straight rod portion 401 and an external threaded portion 402. There are two external threaded portions 402, which are coaxial with the straight rod portion 401. The two external threaded portions 402 are respectively located at both ends of the straight rod portion 401. The straight rod portion 401 passes through multiple grooves 103. The connecting tube 301 is rotatably connected to the straight rod portion 401. The two external threaded portions 402 extend out of the front and rear ends of the through hole 104, respectively. Each external threaded portion 402 extending out of the through hole 104 is connected to a nut 5. Each external threaded portion 402 is connected to two nuts 5.

[0026] The connecting rod 4 is used to connect the hooks 3. In this embodiment, one connecting rod 4 is used to connect multiple hooks 3. In actual use, one connecting rod 4 can be set in each groove 103 and one connecting rod 4 can be connected to one hook 3. However, this method of one connecting rod 4 connecting one hook 3 is more difficult to design and the connection relationship is more complex. The method of one connecting rod 4 connecting multiple hooks 3 in this utility model satisfies both the use and the manufacturing.

[0027] The external threaded part 402 and the nut 5 are provided to fix the connecting rod 4. Two nuts 5 are connected to each external threaded part 402 to prevent the nuts 5 from loosening, which improves the stability of the present invention. The openings of the hook body 302 of the hook 3 connected to the two side suspension plates 102 are opposite to each other.

[0028] The openings of the hook body 302 are opposite to each other, which facilitates the hanging and unhooking of ton bags into and out of the hook body 302.

[0029] Hook body 1 is made of Q345B; hook 3 is made of Q345B; connecting rod 4 is made of Q345B; and eyelet 2 is made of Q345B.
