[0017] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Please see Figures 1 to 4 This utility model provides a technical solution: a container lifting anti-fall safety device, including...

[0019] A lifting frame 1 is provided. A rotating machine 2 is fixedly installed on the side of the lifting frame 1. A rotating wheel 3 is fixedly installed at the output end of the rotating machine 2. An adjusting steel cable 4 is slidably installed on the side of the rotating wheel 3. A connecting seat 5 is fixedly installed on the side of the lifting frame 1. A first pulley 6 is installed on the side of the connecting seat 5. The first pulley 6 is slidably connected to the adjusting steel cable 4. A movable ball 7 is fixedly installed on the side of the adjusting steel cable 4. Multiple sets of movable balls 7 are provided. A protective steel cable 8 is fixedly installed on the side of the movable ball 7. Multiple sets of protective steel cables 8 are provided. The length of the protective steel cables 8 in each set is different. A track assembly is slidably installed on the side of the movable ball 7. The rotating wheel 3 drives the adjusting steel cable 4 to move. The adjusting steel cable 4 is fixedly connected to the movable ball 7, thereby enabling the movable ball 7 to move within the track assembly. During the movement of the movable ball 7, multiple sets of movable balls 7 drive the protective steel cables 8 from a vertical state to a horizontally extended state, providing additional support and locking protection for the container.

[0020] A traction seat 9 is fixedly installed on the top of the hoisting frame 1. A traction rope 10 is fixedly connected to the top of the traction seat 9 via a hinge seat. A second pulley 11 is fixedly installed on the side of the traction seat 9, and the fixed pulley is slidably connected to the adjusting steel cable 4.

[0021] The track assembly includes a first track 12, with a vertical groove 13 on the side of the first track 12, and a movable ball 7 is slidably disposed in the vertical groove 13. When the movable ball 7 is in the vertical groove 13, the movable ball 7 can carry the protective steel cable 8 fixedly connected to the side in a vertically contracted state, which facilitates the subsequent docking and fixing operation of the hoisting frame 1 on the container.

[0022] A second track 14 is fixedly installed at the bottom of the first track 12. A horizontal groove 15 is opened at the bottom of the second track 14, and the adjusting steel cable 4 is built into the horizontal groove 15. When the moving ball 7 is in the horizontal groove 15 of the second track 14, the moving ball 7 can carry the protective steel cable 8 fixedly connected to the side in a vertically horizontally extended state. When the lifting frame 1 carries the container for transportation, the protective steel cable 8 forms a fall prevention safety net at the bottom of the container, ensuring the firmness and stability of the connection between the lifting equipment and the container, and effectively avoiding the risk of the container falling due to the loose connection at the top of the container body of the lifting frame 11.

[0023] The top of the second track 14 groove is fixedly connected to an anti-wear block 16, and the anti-wear block 16 is slidably connected to the adjusting steel cable 4. The anti-wear block 16 is used to connect the track assembly and the adjusting steel cable 4 to reduce the wear between the adjusting steel cable 4 and the track assembly during the movement process.

[0024] In practical use: First, the traction rope 10, hinged at the top of the traction seat 9, is connected to the external power machinery. Then, the power machinery moves the entire lifting frame 1 via the traction rope 10. When the lifting frame 1 moves to the top of the container to be transported, the rotating machine 2 is started. The rotating machine 2 drives the rotating wheel 3 at the output end to rotate, and the rotating wheel 3 drives the adjusting steel cable 4 to move. The adjusting steel cable 4 and the moving ball 7 are fixedly connected. The moving ball 7 needs to be moved to the vertical groove 13 position in the first track 12 by adjusting the movement of the steel cable 4. At this time, the moving ball 7 can be in a vertically contracted state with the protective steel cable 8 fixedly connected to the side, which facilitates the subsequent docking and fixing operation of the lifting frame 1 on the container. Then, the entire... The lifting frame 1 is docked and fixed to the top of the container. After the fixing is completed, the lifting frame 1 and the container are raised to a certain height using a power machine. Then, the rotating machine 2 is used to move the moving ball 7 by adjusting the steel cable 4. When the moving ball 7 is in the horizontal groove 15 of the second track 14, the moving ball 7 can be in a vertical and horizontally extended state with the protective steel cable 8 fixed on the side. When the lifting frame 1 is transporting the container, the protective steel cable 8 forms a fall prevention safety net at the bottom of the container, ensuring the firmness and stability of the connection between the lifting equipment and the container body. This effectively avoids the risk of the container falling due to the loose connection of the top of the container body of the lifting frame 1, and provides additional support and locking protection for the container.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
