Description

Technical Field

[0001] This utility model relates to the field of container bag technology, and in particular to a container bag hoisting device. Background Technology

[0002] FIBCs (Flexible Intermediate Bulk Containers) are flexible transport packaging containers widely used for transporting powdery, granular, and lumpy goods such as food, grains, pharmaceuticals, chemicals, and minerals.

[0003] In the actual transportation of FIBCs (Flexible Intermediate Bulk Containers), forklifts or cranes are used, but the following problems exist:

[0004] 1. When forklifts transport FIBCs, the FIBCs placed on the forklifts are prone to falling off and need to be reloaded, which affects efficiency. In addition, forklifts are inconvenient to operate when transporting indoors.

[0005] 2. The lifting method involves using a hook to lift the slings of the container bag. However, during the lifting process, the slings are very easy to detach from the hook, causing great inconvenience to the user. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a container bag lifting device that is stable in lifting, simple in structure, and highly efficient.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] A container bag lifting device includes a lifting frame, on which lifting rings are fixedly installed, and at the lower end of the lifting frame, four lifting components arranged in a rectangular pattern are fixedly installed.

[0009] The hoisting assembly includes a mounting plate fixedly connected to the hanger. A boom is fixedly mounted on the lower end of the mounting plate. The boom is L-shaped, and the outer end of the boom bends upward to form a retaining edge. The boom and the retaining edge form a hoisting opening. A limiting structure for blocking and limiting the hoisting opening is installed on the boom.

[0010] In this configuration, the gantry crane connects to the overhead crane. When lifting the FIBC (Flexible Intermediate Bulk Container), both sides of the FIBC are secured with lifting straps. Two lifting components on the same side of the gantry crane lift the same strap. When connecting the lifting components to the straps, the straps are placed inside the lifting opening, with a stop edge blocking one side of the straps. A limiting structure then restricts the straps within the lifting opening to prevent them from detaching. The FIBC can then be lifted using the overhead crane and gantry crane. Once the FIBC is in position, the limiting structure releases the restriction on the lifting opening, and the operator can remove the straps.

[0011] The limiting structure includes a slip ring and a limiting ring fixedly connected to the slip ring. The slip ring slides with the boom, and the opening of the limiting ring is located outside the flange in the vertical direction.

[0012] The boom has two fixed supports, and a hanging arm is rotatably mounted on each support. The hanging arm is L-shaped, and an inclined connecting rod is fixed to the upper end of the hanging arm. The two connecting rods are fixedly connected by a handle.

[0013] The length of the hanging arm is 1.5 times the length of the slip ring.

[0014] The boom and the mounting plate are fixed with several spaced stiffening plates.

[0015] In summary, this container bag lifting device has the advantages of stable lifting, simple structure, and high efficiency. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. In the description of the present invention, it should be understood that directional terms such as "upper," "lower," "top," and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0022] like Figure 1-5 As shown, a container bag hoisting device includes a hoist 1, on which a hoisting ring 2 is fixedly installed, and at the lower end of the hoist four hoisting components arranged in a rectangular pattern are fixedly installed.

[0023] The hoisting assembly includes a mounting plate 3 fixedly connected to the hanger. A boom 4 is fixedly mounted on the lower end of the mounting plate. The boom is L-shaped, and the outer end of the boom bends upward to form a retaining edge 5. The boom and the retaining edge form a hoisting opening 6. A limiting structure for blocking and limiting the hoisting opening is installed on the boom.

[0024] In this configuration, the gantry crane connects to the overhead crane. When lifting the FIBC (Flexible Intermediate Bulk Container), both sides of the FIBC are secured with lifting straps. Two lifting components on the same side of the gantry crane lift the same strap. When connecting the lifting components to the strap, the strap is placed inside the lifting opening, with a side guard blocking one side of the strap. A limiting structure then restricts the strap within the lifting opening, preventing it from detaching. The FIBC is then lifted using the overhead crane and gantry crane. Once in position, the limiting structure releases the restriction on the lifting opening, and the operator can remove the strap. The use of the boom, side guard, and limiting structure effectively prevents the strap from detaching, improving the stability of the lifting process.

[0025] In implementation, the limiting structure includes a slip ring 7 and a limiting ring 8 fixedly connected to the slip ring. The slip ring slides with the boom, and the opening of the limiting ring is located outside the side flange in the vertical direction. The slip ring slides along the boom. When a sling needs to be placed in the lifting opening, the slip ring is pushed upwards, causing the limiting ring to move upwards. After the sling enters the lifting opening through the gap between the limiting ring and the side flange, the slip ring is released, and the limiting ring reaches the outside of the side flange, blocking the sling. When it is necessary to remove the sling, the slip ring is slid upwards, the limiting ring disengages from the side flange, and the sling can be removed from the gap between the limiting ring and the side flange.

[0026] In practice, two supports are fixed on the boom, and a hanging arm 9 is rotatably mounted on the supports. The hanging arm is L-shaped, and an inclined connecting rod 0 is fixed to the upper end of the hanging arm. The two connecting rods are fixedly connected by a handle 11. By setting up the hanging arm, when the slip ring reaches the bottom, the hanging arm is in contact with the boom, and the hanging arm blocks and limits the slip ring, which can better limit the movement of the sling.

[0027] In practice, the length of the hanging arm is 1.5 times the length of the slip ring. When it is necessary to remove the sling, the hanging arm is rotated to release the limit on the slip ring, then the slip ring is moved upward, the hanging arm returns to its original position, and the hanging arm engages with the slip ring, making it easy for the operator to remove the sling.

[0028] During implementation, several spaced stiffening plates 12 are fixed between the boom and the mounting plate to improve strength.

[0029] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
