[0002] In the field of power construction, drone hoisting has become a core tool for transporting and hoisting equipment across complex terrains (such as mountains and rivers) due to its flexibility, mobility, and the fact that it does not require scaffolding or road closures. For example, it is used for: insulation coating of overhead bare conductors, anti-icing coating spraying, de-icing operations, insulator inspection, hardware flaw detection, and strand repair. With the advancement of "smart grid" construction, the combination of drones and intelligent equipment has become a key to industry upgrading.

[0024] It should be noted that in logistics handling, warehousing and loading / unloading, construction and other fields, the hoisting of goods or heavy objects is one of the core links, and its efficiency and safety directly determine the overall operational efficiency of the production process. The current mainstream hoisting and loading method is still mainly "manual assisted loading", which has significant limitations and risks. In traditional hoisting operations, it is necessary to manually connect and fix the lifting tools (such as hooks and ropes) to the loading point, and then complete the lifting with the cooperation of the signalman and the crane operator. This process requires the cooperation of multiple people and is limited by the speed of manual operation. In the scenario of batch cargo turnover or large component hoisting, a single loading can take several minutes, which seriously restricts the overall operation efficiency, with high dependence on manual labor and low efficiency. In addition, in adverse environments such as night, rain, snow and fog, the visibility of manual personnel is obstructed, and the accuracy and safety of loading are further reduced, leading to operation interruption or escalation of risks.

[0025] To address the aforementioned issues, this solution provides an automatic loading claw device for hoisting. This application utilizes the elastic potential energy of a tension spring and the mutual cooperation of connecting arm A, connecting arm B, movable hook, and hook pin to drive two sets of movable claws to open and close, enabling remote automatic grabbing and lowering of goods and reducing the difficulty of hoisting.

[0026] For details, please refer to Figures 1-5 , Figure 1 This is a perspective view of the present invention; Figure 2 This is a partial structural schematic diagram of the present invention; Figure 3 This is a rear view of the present invention; Figure 4 The three-dimensional representation of this utility model Figure 2 ; Figure 5 This is a three-dimensional structural diagram of the claw clamp of this utility model in the open state.

[0027] This application provides an automatic mounting claw device for hoisting, including a lifting ring 1 and a hoisting rod 15. The bottom of the lifting ring 1 is connected to a connecting shaft A2. Two sets of connecting arms A3 are sleeved on the outside of the connecting shaft A2. A movable hook 4 is rotatably connected to one set of connecting arms A3, and a hook pin 14 is provided on the other set of connecting arms A3. Both sets of connecting arms A3 are rotatably connected to a connecting shaft C12.

[0028] Connecting arms B5 are connected to connecting shaft C12. The two sets of connecting arms B5 are staggered and rotatably connected by connecting shaft B11. Each connecting arm B5 is provided with a movable claw pin 6, and each movable claw pin 6 is provided with a movable claw 10. A guide rod connector 9 is installed at the bottom of the connecting arm B5. A guide rod 7 is installed at the bottom of each guide rod connector 9. A marker ball 8 is installed at the bottom of each guide rod 7. A tension spring 13 is connected to one end of the connecting shaft A2 and the outer side of the connecting shaft B11.

[0029] During hoisting, the hoisting rod 15 on the cargo to be hoisted slides along the guide rod 7 into the slot formed by the two sets of connecting arms B5. It is then limited by the movable claw 10. The hoisting device is then lifted upwards, and the hoisting rod 15 is locked onto the movable claw 10. The movable claw 10 is subjected to a downward pulling force, the connecting arm A3 rotates and retracts, and the movable hook 4 disengages from the hook pin 14 by gravity. At this time, the tension spring 13 is in a stretched state. When the cargo lands, the hoisting rod 15 rises from the movable claw 10, the tension spring 13 contracts, and the claw opens.

[0030] In this embodiment, the movable hook 4 has a groove, and the groove is adapted to the hook pin 14.

[0031] It should be noted that the groove on the movable hook 4 is engaged with the hook pin 14, thereby achieving a fixing effect.

[0032] In this embodiment, the guide rod connector 9 is provided with a slot, and the slot is adapted to the connecting arm B5.

[0033] It should be noted that the connecting arm B5 is inserted into the slot on the guide rod connector 9 to facilitate its assembly and installation.

[0034] In this embodiment, two sets of threaded holes are provided on each connecting arm B5, and two sets of through holes are provided at the bottom of both ends of the guide rod connector 9. The guide rod connector 9 is locked to the bottom of the connecting arm B5 by screws.

[0035] It should be noted that screws are inserted into the two sets of through holes and then tightened to install the guide rod connector 9 onto the connecting arm B5.

[0036] In this embodiment, the connecting arm B5 has an L-shaped structure.

[0037] It should be noted that the L-shaped connecting arms B5, due to their intersecting structure, form an opening that accommodates the lifting rod 15.

[0038] In this embodiment, the movable claw 10 is secured to the movable claw pin 6 by a hexagonal screw.

[0039] It should be noted that the two sets of movable claws 10 serve as limiters, and can be opened and closed by the movement of the two sets of connecting arms B5, so as to grasp and put down the goods.

[0040] Before hoisting, manually hook the movable hook 4 onto the hook pin 14;

[0041] During hoisting, the hoisting rod 15 on the goods to be hoisted slides along the guide rod 7 into the slot below the two sets of connecting arms B5, and is limited by the movable claw 10. Then the hoisting device is lifted upward, the hoisting rod 15 is locked on the movable claw 10, the movable claw 10 is pulled downward, the connecting arm A3 rotates and retracts, and the movable hook 4 is disengaged from the hook pin 14 by gravity. At this time, the tension spring 13 is in a stretched state.

[0042] Once the goods are on the ground, the lifting boom 15 rises from the movable claw 10, the tension spring 13 contracts, the claws open, and the goods are unhooked.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
