DETAILED DESCRIPTION
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Refer to the instruction manual appendix Figures 1-4 ,like Figure 1 As shown in the figure, a multifunctional overhead crane tool maintenance platform anti-fall device according to an embodiment of the present invention includes a main body 1, a lifting frame 2 provided on the inner side of the main body 1, and a maintenance platform 3 fixedly installed on the top of the lifting frame 2. Figure 2 As shown, a shaft 4 is rotatably connected to one side of the maintenance platform 3. A fall arrestor 5 is fixedly installed at one end of the shaft 4. A transmission plate 6 is fixedly installed on one side of the fall arrestor 5. A frame plate 7 is fixedly installed at the bottom of the transmission plate 6. A spring 8 is provided on the inner side of the frame plate 7. The spring 8 is fixedly installed at the bottom of the maintenance platform 3. A pull rope 9 is fixedly installed on one side of the transmission plate 6. A fixed frame 10 is fixedly installed at the bottom of the maintenance platform 3. A guide wheel 11 is rotatably connected inside the fixed frame 10. The pull rope 9 is slidably connected to the inner side of the guide wheel 11. A limit post 12 is fixedly installed at the bottom of the maintenance platform 3. A movable plate 13 is slidably connected to the outer side of the limit post 12. The pull rope 9 is fixedly installed on the top of the movable plate 13. A branch rope 14 is fixedly installed at the bottom of the movable plate 13. Figure 1 As shown, a transmission rope 15 is fixedly installed at the bottom end of the branch rope 14. The transmission rope 15 is fixedly installed on the inner side of the main body 1. An extension baffle 16 is slidably connected to the inner side of the fall arrestor baffle 5. A protective net rope 17 is fixedly installed on one side of the extension baffle 16. Figure 4 As shown, a fixed post 18 is slidably connected to one side of the extension baffle 16, and the fixed post 18 is slidably connected inside the fall arrestor baffle 5.
[0020] It should be noted that, during the maintenance of the multi-functional overhead crane using the maintenance platform, the lifting frame 2 drives the maintenance platform 3 to rise. When the maintenance platform 3 reaches its highest point, the transmission rope 15 gradually tightens, thereby pulling the movable plate 13 downward. The movable plate 13 then pulls multiple pull ropes 9, causing the transmission plate 6 to rotate. Simultaneously, the spring 8 contracts. As the transmission plate 6 rotates, the fall arrestor 5 rotates outward. The transmission plate 6 stops after contacting the bottom of the maintenance platform 3. At this point, multiple fall arrestor 5s tilt outward, and the protective net rope 17 unfolds. By pushing the fixing column 18 upward, the extension baffle 16 slides out from the inside of the fall arrestor 5. The fixing column 18 stops after sliding to its highest point and then slides to one side, allowing it to enter... Figure 4The position is shown, thereby completing the fixing of the extending baffle 16, at this time, the falling prevention baffle 5 is blocked with the protective net rope 17, thereby achieving the falling prevention purpose, and the operation is convenient, without manual additional intervention, and the safety performance is greatly improved.
