DETAILED DESCRIPTION

[0023] The technical solutions of the utility model will be described clearly and completely in combination with the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0024] Referring to Figures 1-4 The utility model provides a technical scheme:

[0025] A self-positioning cylindrical inner support hoisting tool, comprising a first support arm 1, a second support arm 2, a folding arm 3, a force arm 4 and a guide cylinder 5, the middle part of the first support arm 1 is fixedly connected with the lower end of the second support arm 2, the middle part of the folding arm 3 is slidably arranged on the middle part of the second support arm 2, the two end parts of the folding arm 3 are provided with the force arm 4, the upper end of the force arm 4 is hinged with the folding arm 3, the corner of the force arm 4 is hinged with the end part of the first support arm 1, the folding arm 3 is fixedly provided with the guide cylinder 5, the guide cylinder 5 is slidably provided with a limiting pin 6, the guide cylinder 5 is provided with a guide groove 7, the limiting pin 6 is provided with a sliding rod 8 in sliding fit with the guide groove 7, the second support arm 2 is provided with a fixed block 9, the fixed block 9 is provided with a fixed groove 10, and the lower end of the limiting pin 6 is provided with a limiting end 11 in fit with the fixed groove 10. Among them, the first support arm 1 and the second support arm 2 are the basic structure of the whole tool, and together build a stable frame that can withstand the weight in the hoisting process. When the folding arm 3 drives the force arm 4 to rise, the end part of the force arm 4 spreads to both sides, and vice versa. The folding arm 3 can be folded up in the case of not being used, and the end part of the force arm 4 is retracted, reducing the occupied space, and the folding arm 3 also provides sufficient flexibility to adapt to different working environments and hoisting needs. The force arm 4 is directly in contact with the hoisted object and transmits force, and can withstand the weight of the hoisted object and maintain a stable posture. The combination of the guide cylinder 5 and the limiting pin 6 realizes the self-positioning function of the tool. The guide cylinder 5 provides a sliding track for the sliding rod 8 on the limiting pin 6, and the limiting end 11 at the lower end of the limiting pin 6 is in rotary fit with the fixed groove 10. This design simplifies the positioning process of the tool, improves the accuracy and efficiency of positioning. At the same time, it can also prevent accidental movement or deformation of the tool during use, further enhancing the safety and reliability of the tool. The hinge allows the folding arm 3 and the force arm 4 to rotate relative to each other, thereby realizing the folding function of the tool. This helps to reduce the occupied space of the tool in the non-working state, facilitating transportation and storage. By adjusting the included angle between the folding arm 3 and the force arm 4, different hoisting angles can be adapted. The hinge 13 is usually designed with a locking mechanism that can fix the relative position between the folding arm 3 and the force arm 4 when needed, thereby enhancing the stability of the tool during hoisting.

[0026] The upper end of the guide groove 7 is provided as a vertical groove 12, and the lower end is provided as a spiral groove 13, and the vertical groove 12 communicates with the spiral groove 13. Among them, the vertical groove 12 can provide a more stable vertical direction guide for the sliding rod 8 in the initial stage, ensuring the accuracy of its movement path. While the spiral groove 13 can further respond to the movement of the sliding rod 8 according to a specific spiral trajectory, realizing more complex position changes, and the whole can accurately control the movement path of the sliding rod 8 through the communication of the two, playing a good guiding and limiting role. This structure makes the movement of the sliding rod 8 can be carried out in stages, first in the vertical groove 12 to complete the vertical displacement, and then enter the spiral groove 13 to realize the action related to rotation, so as to better cooperate with the operation of other parts.

[0027] The second support arm 2 is provided with a connecting hook 14. Among them, the connecting hook 14 serves as an important lifting tool, responsible for connecting external hoisting equipment and tooling, ensuring that the tooling can safely and stably lift heavy objects.

[0028] The force arm 4 is provided with a limiting plate 15. Among them, the limiting plate 15 is located on the force arm 4, which helps to guide and position the hoisted object during lifting, ensuring that the object can be smoothly and accurately lifted. The curvature, position and size of the limiting plate 15 and other parameters are determined according to the shape, size and lifting requirements of the hoisted object, so as to ensure the best guiding and positioning effect.

[0029] The end of the force arm 4 is provided with a hook 16. Among them, the hook 16 serves as an extension of the force arm 4, which can directly hook or connect the hoisted object, simplifying the lifting process and improving the work efficiency. It is usually made of high-strength material and can withstand a large tensile force, thereby enhancing the overall carrying capacity of the tooling. This allows the operator to easily connect the tooling to the hoisted object, while also facilitating fine tuning during lifting. By reasonably designing the shape and size of the hook 16, it can ensure that the connection with the hoisted object is firm and reliable, reducing the risk of falling or breaking during lifting.

[0030] The two force arms 4 on the first support arm 1 are symmetrically arranged. Among them, the symmetrical arrangement can ensure that when subjected to external force, the two force arms 4 can evenly share the external force, avoiding local stress deformation of the first support arm 1 due to uneven stress, and improving the overall structural stability and reliability of the first support arm 1. It helps to provide stable and balanced support force for the connected components in different directions under the action of external force, ensuring the stability of the entire device during operation.

[0031] The two folding arms 3 on the second supporting arm 2 are symmetrically arranged. When folding operation is performed, the two symmetrically arranged folding arms 3 can move in a more coordinated and consistent manner, so that the folding process is smoother and more stable, the jamming or interference between components caused by asymmetric movement is reduced, and the force bearing arm 4 can uniformly share external forces in the unfolded state, maintains the structural stability of the second supporting arm 2 and the whole device, and guarantees normal work of the device.

[0032] When the sliding rod 8 slides from the vertical groove 12 to the spiral groove 13, the limiting end 11 on the limiting pin 6 is rotated by 60-90 degrees. Through the movement of the sliding rod 8 in different groove sections, the conversion from linear motion to rotary motion is achieved, so that the limiting end 11 can rotate within the set angle range (60-90 degrees), thereby triggering the operation of other components related thereto to complete specific function switching or action connection. The specified rotation angle can accurately control the amplitude and effect of a series of actions caused by the rotation of the limiting end 11, and ensure the motion accuracy and predictability of the whole device, so that it can stably operate according to the expected work flow.

[0033] A sliding groove 17 is formed on the second supporting arm 2, and a sliding shaft 18 matched with the sliding groove 17 is arranged on the folding arm 3. The sliding groove 17 on the second supporting arm 2 is matched with the sliding shaft 18 on the folding arm 3, so that the folding arm 3 can slide on the second supporting arm 2, further enhancing the flexibility and adaptability of the tooling. This design enables the tooling to adjust the position of the folding arm 3 according to different lifting requirements.
