The top end of the safety rope 31 is arranged outside the winding rope winding device 3. The buckle 32 is fixedly connected to the bottom of the safety rope 31. The safety rope 31 is orderly wound one turn after another by the winding component inside the rope winding device 3, so that the safety rope 31 is neatly placed in the non-construction state, improving the cleanliness of the equipment. At the same time, the buckle 32 is connected with the safety waistband of the worker, so that the safety rope 31 is safely connected with the worker.

[0028] The outer walls of the two sides of the rope winding device 3 are fixedly connected with vertical plates 61. The side walls of the two vertical plates 61 are fixedly connected with supporting plates 62. The two vertical plates 61 can fix the supporting plates 62. The inner wall of the side of the supporting plate 62 away from the vertical plate 61 is provided with a square groove 63. The safety rope 31 is located inside the square groove 63. The inner side wall of the square groove 63 is rotatably connected with a roller 64. The safety rope 31 passes through the gap between the roller 64 and the inner side wall of the square groove 63. When the safety rope 31 is used with the rope winding device 3, the safety rope 31 is located in the gap between the roller 64 and the inner side wall of the square groove 63. The safety rope 31 contacts the roller 64, avoiding the winding of the safety rope 31 during the rising and falling period, so that the safety rope 31 is still freely wound in an emergency, ensuring the safety of the worker in the construction.
