The top side of bottom plate 1 is fixedly connected with tower pole 2, the top end of tower pole 2 is installed with force arm 3, force arm 3 can move in large range in horizontal direction in the operation process of tower crane, to realize the hoisting operation of various building materials. The bottom side right end of force arm 3 is fixedly connected with protective frame 4, drive protective frame 4 synchronous operation in the process of operation by force arm 3, the inner wall bottom side of protective frame 4 is fixedly connected with the drive assembly of pushing subsequent component sliding, drive assembly includes cylinder 5, the bottom side of cylinder 5 is fixedly connected in the inner wall bottom side of protective frame 4, by fixing cylinder 5, so that cylinder 5 can stably provide drive source. The driving end of cylinder 5 is fixedly connected with push rod 6, and the force of driving end of cylinder 5 is transmitted to subsequent component by push rod 6. The top side of drive assembly is fixedly connected with push column 7, and the top side of push rod 6 is fixedly connected in the bottom side of push column 7.

[0032] Push rod 6 is pushed up by force. Rotating shaft 8 is rotatably connected in the inside of protective frame 4, by the limitation of protective frame 4, so that rotating shaft 8 can stably rotate. The left side of rotating shaft 8 is fixedly connected with fixed frame 9, by fixed frame 9 after being pushed, rotating shaft 8 is rotated with rotating shaft 8 as center. The top end of push rod 6 is slidably connected in the inside of fixed frame 9, square opening 10 is arranged in the inside of fixed frame 9, by the limitation of square opening 10, so that fixed frame 9 has enough space to be rotated by the force of push rod 6. The outside of push column 7 is slidably connected in the inside of square opening 10, and the top end of push rod 6 is slidably connected in the inside of square opening 10, by the limitation of square opening 10, so that push rod 6 and push column 7 can stably slide. The outside of push column 7 is slidably connected in the inner wall of fixed frame 9, by push column 7, fixed frame 9 is rotated around rotating shaft 8 as center.

[0033] Refer to Figures 2 to 4The right side of the rotating shaft 8 is fixedly connected with a support column 11, which is driven to rotate by the rotating shaft 8 under stress. The front and rear sides of the support column 11 are fixedly connected with open blocks 12, which provide a moving space for subsequent components. The inside of the open block 12 is fixedly connected with a positioning column 16, which limits the subsequent components. The outside of the positioning column 16 is rotatably connected with a hook-shaped plate 13, which can rotate around the positioning column 16 as the center under the limitation of the positioning column 16. The outside of the hook-shaped plate 13 is rotatably connected inside the open block 12, which can stably rotate under the limitation of the open block 12. The right ends of the two hook-shaped plates 13 are detachably connected with warning lights 14, which play a warning role in the tower crane construction process, reminding passing pedestrians and vehicles to pay attention to safety, especially in the construction site of the viaduct near the village road. When the warning light shines on the village road, it is prohibited to pass through, which greatly improves the safety and convenience of the construction site management; The left side of the warning light 14 is in contact with the right side of the support column 11. The front and rear sides of the warning light 14 are provided with limiting openings 15, which provide a moving space for the hook-shaped plate 13. The right end of the hook-shaped plate 13 is slidably connected inside the limiting opening 15, which completes the clamping of the hook-shaped plate 13 through the limiting opening 15. The proximal side of the two hook-shaped plates 13 is fixedly connected with a reset assembly for resetting the hook-shaped plate 13.

The outside of the two fixed rings 17 is fixedly connected with a torsional spring 18, which provides a reset force for the fixed ring 17.

[0034] Working principle: Push the warning light 14 between the two hook-shaped plates 13, so that the left side of the warning light 14 is in contact with the right side of the support column 11. Continue to push the warning light 14, so that the right end of the hook-shaped plate 13 is clamped into the warning light 14 under the guidance of the limiting opening 15. At this time, the torsional spring 18 is in a stretched state, providing clamping force for the hook-shaped plate 13, ensuring that the warning light 14 is firmly installed. The tower crane starts construction, and the force arm 3 moves in a large range in the horizontal direction to realize the hoisting operation of various building materials. The force arm 3 drives the protective frame 4 to work synchronously, so that the internal warning light 14 can rotate synchronously to warn. When it is necessary to adjust the position of the warning light 14 or perform other operations, start the air cylinder 5, and the driving end of the air cylinder 5 pushes the push rod 6 upward. And push the push column 7 to slide upward. In turn, drive the fixed frame 9 to rotate around the rotating shaft 8. The rotation of the rotating shaft 8 drives the support column 11 to rotate, thereby changing the position of the hook-shaped plate 13 and the warning light 14, so that they can adapt to different angles of warning, thereby improving their flexibility.
