Technical Field

[0001] This utility model relates to a ton bag hoisting connection device, belonging to the technical field of hoisting equipment. Background Technology

[0002] In industrial production and logistics handling, ton bags (also known as bulk containers or jumbo bags) are widely used for the storage and transportation of bulk materials such as granules and powders due to their large capacity and ease of centralized handling. However, the lifting operation of ton bags relies on a hook device connecting the overhead crane and the lifting lugs of the ton bag. Currently, there are many problems in practical applications: during the lifting process, the force on the four lifting straps is not even, which can easily lead to the ton bag tilting, material spillage, or even strap breakage. Direct hooking can easily cause the lifting straps to twist and wear, posing a risk of disengagement and poor safety. Summary of the Invention

[0005] The load-bearing frame includes an annular frame, in which vertically arranged reinforcing plates are symmetrically arranged. The outer ends of the reinforcing plates pass through the annular frame, and the inner ends of the reinforcing plates are located at the center of the annular frame and are fixedly connected. The lifting chain corresponds to the reinforcing plates, and the bottom end of the lifting chain is fixed at the intersection of the annular frame and the reinforcing plates.

[0006] The anti-detachment hook is a hook with an elastic tongue.

[0007] The load-bearing frame is made of high-strength alloy steel.

[0008] The inner side of the anti-detachment hook is provided with a wear-resistant pad.

Detailed Implementation

[0011] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0012] like Figure 1 As shown, this embodiment of a ton bag lifting and connecting device includes a load-bearing frame, which includes an annular frame 1. Four vertically arranged reinforcing plates 6 are symmetrically arranged inside the annular frame 1. The outer ends of the reinforcing plates 6 pass through the annular frame 1, and the inner ends of the reinforcing plates 6 are located at the center of the annular frame 1 and are fixedly connected by welding. Four lifting chains 2 are symmetrically arranged at the top of the annular frame, corresponding to the reinforcing plates 6. The bottom ends of the lifting chains 2 are fixed to the intersection of the annular frame 1 and the reinforcing plates 6. The welded ends of the reinforcing plates 6 and the top ends of the lifting chains 2 are connected by connecting straps 5. The connecting straps 5 are hung on crane hooks or other lifting equipment to ensure uniform force distribution during lifting. Anti-detachment chains 3 are respectively installed at the bottom of the outer ends of the reinforcing plates 6, and anti-detachment hooks 4 are installed at the bottom of the anti-detachment chains 3. The four lifting straps of the ton bag are hung in the corresponding anti-detachment hooks 4 to prevent the ton bag from tilting and detaching, thus improving safety.

[0013] like Figure 2 As shown, the anti-detachment hook 4 is a commercially available hook with an elastic tongue. The elastic tongue provides a restoring force, keeping the hook body closed in its natural state, forming an anti-detachment structure. The anti-detachment hook 4 includes a hook body 4.2, with a shaft hole 4.1 at the top. A bearing is installed in the shaft hole, and a rotating shaft passes through the bearing and the anti-detachment chain 3, connecting the hook body to the anti-detachment chain and allowing the hook to rotate around the rotating shaft. One end of the tongue 4.3 is connected to the hook body via a torsion spring, and the other end of the tongue can open or close the opening of the hook body. Pressing down the tongue opens the opening of the hook body, making it easy to hang the ton bag sling on the anti-detachment hook. Releasing the tongue resets the tongue to close the opening of the hook body, preventing the ton bag sling from falling off.

[0014] The load-bearing frame is made of high-strength alloy steel, which has excellent rigidity and strength.

[0015] Both the anti-derailment chain and the lifting chain use forged lifting rings. The inner surface of the hook is smooth and rounded, and it is also equipped with a wear-resistant pad to reduce wear on the ton bag lifting strap and extend its service life.

[0016] In use, the operator sequentially moves each tongue to insert the four lifting straps of the ton bag into the hook body, then releases the tongues. The tongues automatically close and lock under the action of the torsion spring. Afterwards, the connecting strap is connected via the crane hook, enabling stable lifting of the ton bag. This device has a reasonable structure and is easy to operate. It effectively prevents the ton bag from tilting and swaying, ensures even force distribution during lifting, prevents the ton bag from detaching from the hook, and improves the safety and efficiency of ton bag lifting.

[0017] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
