Description

Technical Field

[0001] This disclosure relates to the field of support technology, and in particular to a ton bag lifting support. Background Technology

[0002] After the ton bag is filled with materials, the lifting strap at the top of the ton bag can be hung on the hook of the crane, and then the ton bag can be lifted by raising the hook. After the ton bag is lifted, there must be a height difference between the unloading port at the bottom of the ton bag and the ground so that the unloading operation can be carried out.

[0003] However, during the process of the hook rising to lift the ton bag, the ton bag undergoes a certain deformation in the height direction to be stretched. However, the height of the production workshop is limited, which causes the unloading port to touch the ground after being lifted, making it impossible to unload the bag. Utility Model Content

[0004] This disclosure provides a ton bag lifting support, which solves a technical problem: by lifting and supporting the ton bag with the ton bag lifting support, the ton bag can be raised to a certain height without being stretched in the vertical direction, so that there is unloading space between the unloading port of the ton bag and the ground to enable unloading operations.

[0005] To address the aforementioned technical problems, this disclosure provides a ton bag lifting support, which may include: a support body and a tray. The support body has an accommodating space, the opening of which is located below the support body, and a first connecting structure is provided at the lower end of the support body. The tray has a second connecting structure and a through hole. The second connecting structure is detachably connected to the first connecting structure, and when the second connecting structure is connected to the first connecting structure, the tray covers the opening, and the through hole is opposite to the unloading port at the lower end of the ton bag located on the tray. The height of the ton bag lifting support is less than the sum of the height of the ton bag's straps and the bag body, but greater than the height of the bag body.

[0006] In some embodiments, the first connecting structure is a hook facing the accommodating space; the second connecting structure is a hooking hole adapted to the hook; when the hook is not hooked into the hooking hole, the size of the opening is a first size; when the hook is hooked into the hooking hole, the size of the opening is a second size, and the second size is smaller than the first size.

[0007] In some embodiments, the support body includes: a first frame and a second frame; the first frame includes: a support frame and a movable frame, the movable frame surrounding the lower end of the support frame to cooperate with the support frame to define an accommodating space, the lower end of the movable frame forming an opening and provided with a hook, and the movable frame and the support frame being rotatably connected; the second frame includes: a hook post and a transmission frame, the hook post slidingly through the center of the support frame in a vertical direction, partially located above the support frame and at least partially located in the accommodating space, the transmission frame being disposed in the accommodating space and connected to the hook post and the movable frame; during the upward sliding of the hook post relative to the support frame, the transmission frame pulls the movable frame to cause the opening at the lower end of the movable frame to contract.

[0008] In some embodiments, the support frame includes: a first rod and a second rod; the movable frame includes: four third rods; the first rod and the second rod are arranged intersecting in a horizontal plane, and the intersection is provided with a through hole for slidingly inserting a hanging post; one end of each of the four third rods is hinged to both ends of the first rod and both ends of the second rod, and the other ends of the four third rods hang down naturally and are each provided with a hook.

[0009] In some embodiments, the transmission frame includes: two fourth rods, which are arranged crosswise and connected to a hanging post at the intersection; the four ends of the two fourth rods are respectively rotatably connected to four third rods; each fourth rod includes multiple segments rotatably connected in sequence along its length.

[0010] In some embodiments, any fourth rod includes: a first segment and a second segment; one end of the first segment is connected to a hanging post; one end of the second segment and the other end of the first segment are respectively provided with a first hole and a second hole, a first pin passes through the first hole and the second hole and enables the first segment and the second segment to rotate relative to each other, and the other end of the second segment is rotatably connected to the third rod through a bearing.

[0011] In some embodiments, the transmission frame includes: two fifth rods, which are arranged crosswise and connected to a hanging post at the intersection; the four ends of the two fifth rods are respectively connected to four third rods; any fifth rod is elastic to be able to bend.

[0012] In some embodiments, the portion of the mounting post located above the support frame is provided with a hanging ring.

[0013] In some embodiments, the tray includes a body and side panels surrounding a perimeter of the upper surface of the body, the body having through holes and the side panels having hook holes.

[0014] In some embodiments, the number of through holes is multiple; the tray also includes multiple closures, each of which is connected to a corresponding through hole, and the closures are capable of opening or closing the corresponding through holes.

[0015] Through the above technical solution, the ton bag lifting bracket provided in this disclosure includes a bracket body and a pallet. The bracket body has a accommodating space, the opening of which is located below the bracket body and can be covered by the pallet after the bracket body and the pallet are connected. In this way, the ton bag can be placed in the accommodating space of the ton bag lifting bracket and lifted by the pallet. The hook of the crane can lift the ton bag lifting bracket to a height that provides unloading space between the ton bag and the ground. Since the height of the ton bag lifting bracket is less than the sum of the height of the ton bag's straps and the bag body but greater than the height of the bag body, the height requirement is less than the height required for the hook to directly lift the ton bag. Thus, the lifting of the ton bag can be achieved in production workshops with limited height. After lifting, the unloading port of the ton bag can unload through the through hole on the pallet to the ground below the ton bag lifting bracket, thereby realizing the unloading operation.

[0030] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0031] After the ton bag is filled with material, the lifting straps at the top of the ton bag can be hooked onto the crane hook. The ton bag can then be lifted by raising the hook. After being lifted, the discharge port at the bottom of the ton bag must have a height difference with the ground to allow for unloading. Here, the ton bag consists of a bag body and lifting straps. The upper end of the bag body has a feeding port, and the lower end has a discharge port. The lifting straps are connected to the upper end of the bag body and can be suspended from the hook.

[0032] However, during the process of the hook rising to lift the ton bag, the ton bag undergoes a certain deformation in the height direction to be stretched. However, the height of the production workshop is limited, which causes the unloading port to touch the ground after being lifted, making it impossible to unload the bag.

[0033] In view of the above-mentioned technical problems, this disclosure provides a ton bag lifting support, which includes a support body and a pallet. The support body has a receiving space, the opening of which is located below the support body and can be covered by the pallet after the support body and the pallet are connected. In this way, the ton bag can be placed in the receiving space of the ton bag lifting support and lifted by the pallet. The hook of the crane can lift the ton bag lifting support to raise the ton bag to a height with unloading space between it and the ground. Since the height of the ton bag lifting support is less than the sum of the height of the ton bag's straps and the bag body but greater than the height of the bag body, the height space requirement is less than the height required for the hook to directly lift the ton bag. Thus, the lifting of the ton bag can be achieved in production workshops with limited height. After lifting, the unloading port of the ton bag can unload through the through hole on the pallet to the ground below the ton bag lifting support, thereby realizing the unloading operation.

[0034] See Figures 1 to 4 As shown, the ton bag lifting bracket may include: a bracket body 1 and a tray 2. The bracket body 1 is provided with a receiving space 11, the opening 111 of which is located below the bracket body 1, and a first connecting structure 12 is provided at the lower end of the bracket body 1. The tray 2 is provided with a second connecting structure 21 and a through hole 22. The second connecting structure 21 is detachably connected to the first connecting structure 12. When the second connecting structure 21 is connected to the first connecting structure 12, the tray 2 covers the opening 111 and the through hole 22 is opposite to the unloading port at the lower end of the ton bag on the tray 2. The height of the ton bag lifting bracket is less than the sum of the height of the ton bag's straps and the bag body, but greater than the height of the bag body.

[0035] One method of using this ton bag lifting support is as follows:

[0036] S101: Place tray 2 on the ground;

[0037] S102: Place the ton bag containing the material on pallet 2;

[0038] S103: Move the support body 1 above the tray 2, lower the support body 1 so that the ton bag is located in the accommodating space 11, and then connect the first connecting structure 12 and the second connecting structure 21.

[0039] S104: Connect the support body 1 to the hook of the crane. Raise the hook to lift the support containing the ton bag. If there is unloading space between the lower surface of the pallet 2 and the ground, the lifting can be stopped.

[0040] S105: The unloading port of the ton bag corresponds to the through hole 22, so that the material can be unloaded to the ground or the receiving device on the ground through the through hole 22.

[0041] Here, the sum of the heights of the lifting straps and the bag body of the ton bag is the sum of the heights of the lifting straps and the bag body after being stretched when the hook is directly attached to the lifting straps to lift the ton bag; the height of the bag body is the height of the bag body after being stretched when the hook is directly attached to the lifting straps to lift the ton bag.

[0042] In this embodiment, the ton bag lifting support can include: a support body 1 and a tray 2. The ton bag can be placed in the accommodating space 11 of the support body 1 and supported by the tray 2. The crane hook can lift the ton bag lifting support to raise the ton bag to a height with unloading space between it and the ground. Then, the material in the ton bag can be unloaded to the ground or a receiving device on the ground through the unloading port and through hole 22 at the lower end of the ton bag to complete the unloading operation. Since the height of the ton bag lifting support is less than the sum of the height of the ton bag's straps and the bag body but greater than the height of the bag body, the height requirement is less than the height required for the hook to directly lift the ton bag. In this way, the ton bag can be lifted in a production workshop with limited height, and after lifting, there is unloading space between the unloading port of the ton bag and the ground to carry out the unloading operation.

[0043] In some embodiments, see Figures 1 to 3 As shown, the first connecting structure 12 is a hook facing the accommodating space 11; the second connecting structure 21 is a hooking hole adapted to the hook; when the hook is not hooked into the hooking hole, the size of the opening 111 is the first size; when the hook is hooked into the hooking hole, the size of the opening 111 is the second size, which is smaller than the first size. Thus, after the hook is hooked into the hooking hole, the hook provides a force to the pallet 2 in a direction away from the periphery of the pallet 2, and the pallet 2 is restricted by its own structure so that it cannot be pulled by the hook, thereby making the connection between the hook and the pallet 2 more secure. In particular, when the accommodating space 11 contains a ton bag and during the process of lifting the ton bag with the lifting bracket, the connection between the hook and the pallet 2 becomes even more secure due to the weight of the ton bag itself.

[0044] In some embodiments, see Figures 1 to 3As shown, the support body 1 includes: a first frame 13 and a second frame 14; the first frame 13 includes: a support frame 131 and a movable frame 132, the movable frame 132 is arranged around the lower end of the support frame 131 to cooperate with the support frame 131 to define an accommodating space 11, the lower end of the movable frame 132 forms an opening 111 and is provided with a hook, and the movable frame 132 is rotatably connected to the support frame 131; the second frame 14 includes: a hanging post 141 and a transmission frame 142, the hanging post 141 slides vertically through the center of the support frame 131, is partially located above the support frame 131 and at least partially located in the accommodating space 11, the transmission frame 142 is arranged in the accommodating space 11 and is connected to the hanging post 141 and the movable frame 132; during the process of the hanging post 141 sliding upward relative to the support frame 131, the transmission frame 142 pulls the movable frame 132 to cause the opening 111 at the lower end of the movable frame 132 to contract.

[0045] In other words, the hook post 141 is hooked onto the crane hook. During the process of the ton bag lifting bracket being lifted, the hook post 141 moves upward and drives the transmission frame 142 connected to it to move upward. The part of the transmission frame 142 connected to the movable frame 132 and the support frame 131 connected to the movable frame 132 have a downward displacement relative to the transmission frame 142 under the action of their own weight. At the same time, due to the rotational connection between the support frame 131 and the movable frame 132, the opening 111 at the lower end of the movable frame 132 contracts. Thus, under the combined action of the structure of the ton bag lifting bracket itself and the weight of the ton bag inside, the reliability of the connection between the hook and the pallet 2 is achieved.

[0046] In some embodiments, see Figures 1 to 3 As shown, the support frame 131 may include: a first rod 1311 and a second rod 1312; the movable frame 132 may include: four third rods 1321; the first rod 1311 and the second rod 1312 are arranged intersecting in a horizontal plane, and the intersection is provided with a through hole for slidingly inserting the hanging post 141; one end of the four third rods 1321 is respectively hinged to the two ends of the first rod 1311 and the two ends of the second rod 1312, and the other ends of the four third rods 1321 hang down naturally and are respectively provided with hooks.

[0047] Alternatively, the first rod 1311 and the second rod 1312 intersect to form an X shape, and both are in the same horizontal plane. The two ends of the first rod 1311 and the two ends of the second rod 1312 are respectively rotatably connected to the third rod 1321 extending in the vertical direction. Furthermore, the hanging post 141 passes through the first rod 1311 and also passes through the second rod 1312. The holes for passing through the first rod 1311 and the second rod 1312 are the same. In this way, when the four third rods 1321 are subjected to a force (such as the force of the second frame 14 pulling the four third rods 1321), the lower ends of the four third rods 1321 can be brought together, thereby adjusting the size of the opening 111 from the first size to the second size.

[0048] The first rod 1311 and the second rod 1312 may or may not be perpendicular to each other. The rotatable connection between the end of the first rod 1311 and the third rod 1321 can be achieved by a rotating shaft, bearings, etc.

[0049] In this embodiment, the support frame 131 may include a first rod 1311 and a second rod 1312; the movable frame 132 may include four third rods 1321. The design of these rods is already well-established, thus simplifying the structure of the support frame 131 and the movable frame 132 and reducing their manufacturing costs. Furthermore, the lower ends of the four third rods 1321 hang naturally, so that after the ton bag lifting bracket descends, the hooks on the four third rods 1321 can automatically disengage from their corresponding hook holes due to their own weight.

[0050] In some embodiments, see Figures 1 to 3 As shown, the transmission frame 142 may include: two fourth rods 1421, which are arranged crosswise and connected to the hanging post 141 at the intersection. The four ends of the two fourth rods 1421 are respectively rotatably connected to four third rods 1321. Each fourth rod 1421 includes multiple segments that are rotatably connected in sequence along its length.

[0051] In other words, the X-shaped transmission frame 142 is arranged in the accommodating space 11. The X-shaped transmission frame 142 has four ends and is rotatably connected to four third rods 1321 respectively. The intersection of the transmission frame 142 is connected to the hanging column 141. The part of the hanging column 141 located on the support frame 131 is connected to the hook of the crane. During the process of the hook rising, the transmission frame 142 rises with it. The support frame 131 and the movable frame 132 are subjected to the rising force and their own weight, so that the ends of the support frame 131 (such as the two ends of the first rod 1311 and the two ends of the second rod 1312) and the upper end of the movable frame 132 (such as the upper end of the third rod 1321) rotate relative to each other. The ends of the transmission frame 142 (such as the two ends of each fourth rod 1421) rotate relative to the connected third rod 1321. At the same time, the relative rotation between different sections of the transmission frame 142 can realize the contraction of the opening 111 at the lower end of the four third rods 1321.

[0052] In this embodiment, the transmission frame 142 includes two fourth rods 1421. The design of the rods is already well-established, which simplifies the structure of the transmission frame 142 and reduces its manufacturing cost.

[0053] In some embodiments, see Figures 1 to 4 As shown, any fourth rod 1421 includes: a first segment 14211 and a second segment 14212; one end of the first segment 14211 is connected to the hanging post 141; one end of the second segment 14212 and the other end of the first segment 14211 are respectively provided with a first hole and a second hole, a first pin passes through the first hole and the second hole and allows the first segment 14211 and the second segment 14212 to rotate relative to each other, and the other end of the second segment 14212 is rotatably connected to the third rod 1321 through a bearing. In this way, the first segment 14211 and the second segment 14212 of the fourth rod 1421 can more flexibly provide the force of the hanging post 141 during the upward process to the four third rods 1321 through relative rotation, so as to pull the four third rods 1321, thereby realizing the contraction of the opening 111 at the lower end of the four third rods 1321, and the multi-segment setting method is simple and easy to manufacture.

[0054] In other embodiments, the transmission frame 142 includes two fifth rods (not shown in the figure), which are arranged crosswise and connected to the hanging post 141 at the intersection. The four ends of the two fifth rods are respectively connected to four third rods 1321. Each fifth rod is elastic to be able to bend.

[0055] Here, the fifth rod is elastic, so that it can be pulled and slightly deformed as the hanging column 141 rises. For example, during the process of lifting the ton bag lifting bracket, the third rod 1321 is fixed in position by the support frame 131 and the pallet 2 so that after the opening 111 at the lower end of the four third rods 1321 contracts, the hanging column 141 continues to pull the third rod 1321 upwards until it can no longer pull the third rod 1321, thus causing it to bend in an arc shape to reduce the probability of the fifth rod breaking. Moreover, the elastic setting can restore the original shape for reuse.

[0056] In some embodiments, see Figure 4 As shown, the portion of the mounting post 141 located above the support frame 131 is equipped with a hanging ring 1411. This allows the hanging ring 1411 to be easily attached to the crane hook.

[0057] In some embodiments, see Figure 1 As shown, the tray 2 includes a main body 23 and a side plate 24 surrounding the upper surface of the main body 23. The main body 23 has a through hole 22, and the side plate 24 has a hanging hole.

[0058] Here, the main body 23 can support ton bags, while the side plates 24 on the periphery can stop and restrict the ton bags located on the main body 23 to reduce the probability of the ton bags detaching from the pallet 2. Both the main body 23 and the side plates 24 can be plate-shaped, and since the main body 23 is used to support and overcome the weight of the ton bags themselves, and the side plates 24 are used for stopping and overcoming a smaller portion, the thickness of the main body 23 can be greater than the thickness of the side plates 24.

[0059] In some embodiments, the number of through holes 22 is multiple; the tray 2 also includes multiple closures (not shown in the figure), each of which is connected to a corresponding through hole 22, and the closure can open or close the corresponding through hole 22. Thus, after placing the ton bag on the tray 2, the through hole 22 corresponding to the discharge port on the ton bag can be opened, reducing the workload required to align the discharge port of the ton bag with the through hole 22 when placing the ton bag on the tray 2, which is necessary when only one through hole 22 is present.

[0060] The closure can be slidably mounted on the tray 2, thereby allowing the through hole 22 to be slidably opened and closed; the closure can also be rotatably mounted on the tray 2, thereby allowing the through hole 22 to be rotatably opened and closed; or other configurations may be used.
