At present, the common handling mode has many deficiencies. Generally, the rope is bound for lifting, which is not only complex and time-consuming to operate, but also in the lifting process, the heavy goods are easy to fall due to the loosening and slipping of the rope, which has serious safety hazards; if the ordinary straight rod or hook is used to lift the heavy goods, the contact area is small and lacks a buffer structure, which is easy to cause damage such as extrusion and scratching on the surface of the heavy goods, and at the same time, the hands are unevenly stressed during double-person operation, which is easy to fatigue and has the risk of slipping. In addition, the traditional tool is difficult to flexibly adjust the posture of the heavy goods, and it is difficult to synchronize the force and turning during double-person cooperation, which leads to low handling positioning accuracy, and the position needs to be repeatedly adjusted, which greatly reduces the operation efficiency and cannot meet the urgent needs of efficient and safe handling of heavy goods.

[0009] Compared with related technologies, the heavy object lifting tool provided by this utility model has the following advantages:

[0010] This utility model provides a heavy object lifting tool. The lifting lever is designed for two-person operation, which can greatly reduce the difficulty of moving heavy objects. The rotatable metal hook is aligned with the appropriate lifting position of the heavy object, slowly inserted and hooked, and the heavy object is lifted steadily by applying force. If the posture of the heavy object needs to be adjusted during the process, the metal hook can flexibly drive the heavy object to rotate due to the rotation performance of the thrust ball bearing. The operator can easily and accurately move the heavy object to the designated position. At the same time, the flat structure can increase the contact area with the operator's hands, reduce hand pressure, and prevent slippage and scratches, thus efficiently completing the heavy object moving operation.

[0016] Example 1

[0017] This embodiment provides a heavy object lifting tool, such as... Figures 1-3 As shown, this utility model includes a metal rod 1, which is tubular. A rotating component is provided in the middle of the tubular part of the metal rod 1, and a metal hook 2 is provided below the rotating component.

[0018] In this embodiment, the metal rod 1 is preferably made of high-strength aluminum alloy tubing, which has the advantages of being lightweight and high-strength. This ensures structural rigidity when bearing heavy loads, facilitates operator control, and its load-bearing capacity is sufficient to accommodate the weight range of common industrial heavy objects. The metal hook 2 is forged from high-quality alloy steel, ensuring it will not deform or break during hooking, and possesses sufficient load-bearing capacity and wear resistance. The rotating assembly is used to install the metal hook 2 and allows it to rotate freely, enabling the load to be adjusted in any direction after lifting and facilitating hooking.

[0019] Example 2

[0020] Based on Example 1, such as Figures 1-3 As shown, in this embodiment, a lower hole 13 is provided at the bottom of the metal rod 1 for the metal hook 2 to pass through, and an upper groove is provided at the top of the metal rod 1. A fixing cover 12 is welded to the upper groove, and the fixing cover 12 is flush with the surface of the metal rod 1.

[0021] In this embodiment, the fixing cover 12 is cut off from the metal rod 1, and the rotating component is welded to the middle of the metal rod 1 through the upper groove. After the rotating component is installed, the fixing cover 12 is welded back into the upper groove. On the one hand, this can keep the surface of the metal rod 1 flat, and on the other hand, it can avoid affecting the structural strength of the metal rod 1.

[0022] Example 3

[0023] Based on Example 1, such as Figure 3 As shown, the rotating assembly in this embodiment includes a fixed support 14, which is welded to the inside of the metal rod 1. A thrust ball bearing 15 is fixedly installed inside the fixed support 14, and a support seat 16 is fixedly installed on the top of the thrust ball bearing 15. The support seat 16 is fixedly connected to the metal hook 2.

[0024] In this embodiment, the bottom of the fixed support 14 is cut into an arc shape that matches the inner wall of the metal rod 1, and is fixed to the metal rod 1 by welding. After the thrust ball bearing 15 is placed, the support seat 16 is placed, which allows the support seat 16 to rotate freely, thereby driving the metal hook 2 to rotate.

[0025] Example 4

[0026] Based on Example 1, such as Figure 4As shown, the top of the metal hook 2 in this embodiment is integrally formed with a mounting post 21, and a pin hole 22 is provided on the side of the mounting post 21. A central hole for the mounting post 21 to pass through is provided in the middle of the support base 16. A pin 17 is inserted into the mounting post 21. An arc-shaped groove 161 for placing the pin 17 is provided on the top of the support base 16. An anti-detachment ring 162 restricting the movement of the pin 17 is integrally formed on the top of the support base 16. The diameter of the lower hole 13 is not less than the diameter of the mounting post 21.

[0027] In this embodiment, the top of the metal hook 2 is fixed on the support base 16 through the engagement of the pin hole 22 and the pin shaft 17. The top of the metal hook 2 can pass through the lower hole 13, which facilitates the fixing of the metal hook 2.

[0028] Implementation steps:

[0029] During transport, two operators hold the flat structures 11 at both ends of the metal rod 1, align the metal hooks 2 with suitable lifting positions on the heavy object, such as lifting holes, grooves, or edges, or use straps to create suitable lifting positions, and slowly insert and hook them. Apply force smoothly to lift the heavy object. If the object's posture needs adjustment during the process, the metal hooks 2 can flexibly rotate the object thanks to the rotational performance of the thrust ball bearing 15. Operators can easily and accurately move the heavy object to the designated position. Simultaneously, the flat structure 11 increases the contact area with the operator's hands, reducing hand pressure and preventing slippage and scratches, thus efficiently completing the heavy object transport operation.
