Detailed Description

The utility model will be further illustrated by the following examples, which are intended only for a better understanding of the present invention and therefore do not limit the scope of the utility model.

As shown in fig. 1 to 3, the aerial work safety rope anchoring device includes two groups of steel wire ropes 1, and each group of two steel wire ropes 1. One ends of the two groups of steel wire ropes 1 are connected with each other through a connecting piece, and the other ends of the two groups of steel wire ropes are locked and fixed with the shear wall 2 through a wall penetrating piece. The wall penetrating piece comprises a protective sleeve 3 and two connecting rods 4 which are in inserting fit with the protective sleeve 3. The protective sleeve 3 penetrates through a reserved hole of the shear wall 2. One ends of the two connecting rods 4 are hinged with each other, and the other ends are fixedly connected with the two steel wire ropes 1 respectively. In order to prevent the connecting rod 4 from wearing the shear wall 2, the connecting rod 4 is sleeved with a rubber protective sleeve. Wherein, two connecting rods 4 are sleeved with a rubber ring which can slide to the tail end of the steel wire rope 1. After the connecting rods 4 penetrate out of the shear wall 2, the rubber ring is slid to the tail end of the steel wire rope 1, the hinged part of the two connecting rods 4 is opened, the rubber ring is pushed forwards to lock the connecting rods 4, and the connecting rods 4 are guaranteed to be clamped outside the shear wall 2 all the time during construction. The diameter of the connecting rod 4 is less than half of the inner diameter of the protective sleeve. In the embodiment, the diameter of the reserved hole of the shear wall 2 is 300 mm; the outer diameter of the protective sleeve 3 is 295mm, and the inner diameter is 290 mm; the diameter of the connecting rod 4 is 85 mm.
