Description

Technical Field

[0001] This utility model relates to the field of hoisting device technology, specifically to an auxiliary hoisting device for loading ton bags. Background Technology

[0002] A ton bag is a flexible transport packaging container that is widely used for the transfer and storage of various materials due to its convenient storage and low cost. It has advantages such as moisture-proof, dust-proof, radiation-resistant, and sturdy and safe. It is also highly efficient in loading, unloading, and handling. However, currently, when loading ton bags, the hook of the hoist is used directly to lift the ton bag. However, the hook cannot hold all four lifting straps of the ton bag, which leads to an imbalance of force on the ton bag during the lifting process, causing it to tilt and spill the material inside. There is also a possibility that the hook may completely detach from the lifting straps of the ton bag, causing it to fall from a height, which poses a certain danger. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an auxiliary hoisting device for loading ton bags, which can improve the stability of ton bag hoisting during the loading process and avoid the situation where the hook is partially or completely separated from the four ton bag hoisting straps.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0005] A ton bag loading auxiliary hoisting device includes a hoisting support, which consists of a horizontal frame and vertical frames on both sides of the horizontal frame. An electric hoist is slidably mounted on the horizontal frame, and the movable end of the chain on the electric hoist is connected to a hook. The hook is connected to a balancing component used to balance the forces on the four sides of the ton bag and assist in hoisting the ton bag. The balancing component includes a cross-shaped bracket, which consists of two mutually perpendicular horizontal bars. The top surfaces of the horizontal bars are respectively provided with limiting hooks for connecting to the lifting straps on the ton bag. A connecting plate is provided at the top center of the cross-shaped bracket, and a lifting ring connected to the hook is provided at the center of the connecting plate.

[0006] In the aforementioned auxiliary hoisting device for loading ton bags, the upper part of the limiting rod is threaded, and a limiting plate is threadedly connected to the limiting rod to press against the ton bag lifting strap and prevent the ton bag lifting strap from coming off the top of the limiting rod.

[0007] In the aforementioned auxiliary hoisting device for loading ton bags, the chain and the hook are connected by a connector.

[0008] The aforementioned auxiliary hoisting device for loading ton bags includes an electric hoist with its top slidably connected to a transverse frame via a sliding trolley. The sliding trolley comprises L-shaped supports symmetrically arranged on the top of the electric hoist with adjustable spacing. These L-shaped supports are arranged along the length of the transverse frame and symmetrically about it. A vertical mounting plate is connected to the vertical portion of the L-shaped supports, and the bottom surface of the vertical mounting plate is positioned on the horizontal portion of the L-shaped supports. On opposite sides of the vertical mounting plate are pulleys slidably connected to a support rail at the bottom of the transverse frame. One pulley on the vertical mounting plate is coaxially arranged with a driven gear, and the vertical mounting plate also has a driving gear that meshes with the driven gear. The driving gear is driven by a moving motor mounted on the vertical mounting plate.

[0009] The aforementioned auxiliary hoisting device for loading ton bags is connected between the L-shaped supports on both sides of the transverse frame by a bidirectional long screw. The L-shaped supports and the bidirectional long screw are slidably connected. Both ends of the bidirectional long screw are provided with external threads. Both ends of the bidirectional long screw pass through the vertical mounting plates at the corresponding ends and are locked to the vertical mounting plates by locking nuts.

[0010] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.

[0011] This utility model provides an auxiliary hoisting device for ton bag loading. It uses a cross-shaped bracket, limiting rods, and lifting rings to assist in hoisting the ton bags, ensuring stability during the loading process. Each ton bag lifting strap is hung on evenly distributed limiting rods, ensuring uniform force on all four sides of the ton bag. At the same time, a limiting plate is set above the limiting rods to press down on the ton bag lifting straps and prevent them from detaching from the limiting rods. This solves the problem that the hook is prone to detaching from the ton bag lifting straps when hoisting ton bags, thus improving the stability of ton bag loading. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] Auxiliary hoisting device for loading ton bags, such as Figures 1 to 4 As shown, it includes a hoisting bracket 1, which consists of a horizontal frame 2 and vertical frames set on both sides of the horizontal frame 2. An electric hoist 3 is installed on the horizontal frame 2, and the top of the electric hoist 3 is slidably connected to the horizontal frame 2 through a sliding trolley 4.

[0019] The movable end of the chain 5 on the electric hoist 3 is connected to the hook 10. The chain 5 and the hook 10 are connected by a connector 11. The hook 10 is connected to a balancing component used to balance the force on the four sides of the ton bag and assist in the lifting of the ton bag. The hook 10 can be either a hook with an anti-detachment plate or a hook without an anti-detachment plate.

[0020] The balancing assembly includes a cross-shaped bracket, which consists of two mutually perpendicular horizontal bars 7. The top surfaces of the horizontal bars 7 are respectively provided with limiting hanging rods 8 for connecting with the slings on the ton bag. A connecting plate 6 is provided at the top center of the cross-shaped bracket, and a lifting ring 9 connected to the hook 10 is provided at the center of the connecting plate 6.

[0021] Specifically, the two crossbars 7 are welded together, and the connecting plate 6 is welded to the center of the top of the cross-shaped bracket, which can ensure the stability of the balance component during hoisting.

[0022] In this embodiment, the crossbar 7 is an I-beam structure, and the limiting rod 8 is welded to the crossbar 7 to ensure the stability of the limiting rod.

[0023] In other embodiments, the crossbar 7 is a steel column structure, and the limiting rod 8 is slidably mounted on the crossbar 7. Specifically, the crossbar 7 is provided with a sliding groove, and the bottom of the limiting rod 8 passes through the sliding groove and is locked to the crossbar 7 by a locking bolt. An anti-loosening washer is provided between the locking bolt and the end face of the crossbar 7. By adjusting the position of the limiting rod on the crossbar, it can accommodate ton bags of different sizes.

[0024] The upper part of the limit rod 8 is threaded, and a limit plate is threadedly connected to the limit rod 8 to press on the ton bag sling and prevent the ton bag sling from coming off the top of the limit rod.

[0025] The sliding trolley 4 includes L-shaped brackets 12 symmetrically arranged on the top of the electric hoist 3 with adjustable spacing. The L-shaped brackets 12 are arranged along the length of the transverse frame 2 and symmetrically arranged about the transverse frame 2. The vertical part of the L-shaped brackets 12 is connected to a vertical mounting plate 13, and the bottom surface of the vertical mounting plate 13 is arranged on the horizontal part of the L-shaped brackets 12.

[0026] On the opposite side of the vertical mounting plate 13, there are pulleys 17 that are slidably connected to the support rail 18 at the bottom of the horizontal frame 2. One of the pulleys 17 on the vertical mounting plate 13 is coaxially arranged with the driven gear 16, and the vertical mounting plate 13 is also provided with a drive gear 15 that meshes with the driven gear 16. The drive gear 15 is driven by a moving motor 14 mounted on the vertical mounting plate 13.

[0027] The pulley moves along the support rail through the transmission of the drive gear and driven gear, thereby adjusting the position of the electric hoist according to the position of the ton bag, making it easier to lift the ton bag.

[0028] The L-shaped brackets 12 located on both sides of the horizontal frame 2 are connected by a bidirectional long screw 19. The L-shaped brackets 12 and the bidirectional long screw 19 are slidably connected. Both ends of the bidirectional long screw 19 are provided with external threads. Both ends of the bidirectional long screw 19 pass through the vertical mounting plates 13 at the corresponding ends and are locked to the vertical mounting plates 13 by locking nuts 20.

[0029] By adjusting the distance between the two L-shaped brackets and then locking the bidirectional long screw to the vertical mounting plate with the lock nut, the electric trolley can be matched with horizontal frames of different sizes, and the stability of the electric trolley operation can be guaranteed.

[0030] When using it, first, start the electric hoist and lower the hook close to the ton bag. Then, hang the lifting ring hook on the top of the balance component onto the hook. Next, hang the four lifting straps of the ton bag onto the limit rods. The cooperation between the limit rods and the cross-shaped brackets ensures that the ton bag is balanced. Furthermore, by installing limit plates on the top of the limit rods and pressing them onto the lifting straps, the lifting straps are prevented from coming off. Then, use the electric hoist to lift the ton bag and load it.

[0031] The electric hoist used in this utility model is a commercially available product, mainly used for lifting, moving, loading and unloading heavy objects. The electric hoist used in this application is a chain electric hoist, but other types of electric hoists, such as wire rope electric hoists, can also be selected according to needs.

[0032] This utility model provides an auxiliary hoisting device for ton bag loading. It uses a cross-shaped bracket, limiting rods, and lifting rings to assist in hoisting the ton bags, ensuring stability during the loading process. Each ton bag lifting strap is hung on evenly distributed limiting rods, ensuring uniform force on all four sides of the ton bag. At the same time, a limiting plate is set above the limiting rods to press down on the ton bag lifting straps and prevent them from detaching from the limiting rods. This solves the problem that the hook is prone to detaching from the ton bag lifting straps when hoisting ton bags, thus improving the stability of ton bag loading.
