Detailed Description

The following describes the embodiments of the present utility model in further detail with reference to the drawings.

As shown in fig. 1 to 4, the utility model comprises a shell 1, a lifting hook 2 is arranged above the shell 1, a first rotating shaft 3 is arranged in the shell 1, a first reel 4 is arranged on the first rotating shaft 3, a first safety rope 5 is wound on the first reel 4, and a limiting device is fixed on the front side surface of the first reel 4; the limiting device comprises a disc 6, a plurality of blind holes 7 are uniformly distributed on the circumference of the disc 6, pins 8 are arranged in the blind holes 7, and springs 9 are arranged between the pins 8 and the blind holes 7; a limiting block capable of blocking the pin 8 is arranged in the shell 1;

a second rotating shaft 10 is arranged in the shell 1, a ratchet wheel 11 is arranged on the second rotating shaft 10, a second wire wheel 12 is arranged on the front side surface of the ratchet wheel 11, and a second safety rope 13 is wound on the second wire wheel 12; a motor is arranged in the shell 1 and can drive the second wire wheel 12 to rotate so as to shrink the second safety rope 13.

In order to realize the start of the motor, a push switch 14 is arranged on the left side surface of the limiting block, and after the push switch 14 is pushed once, the motor can drive the second wire wheel 12 to rotate, so that the second safety rope 13 is contracted.

For convenient use, a torsion spring is arranged between the first reel 4 and the rotating shaft, and the first safety rope 5 can reset under the action of the torsion spring after being stretched.

In order to realize the driving of the motor, a storage battery and a control circuit are arranged in the shell 1.

In order to facilitate the rotation of the first safety rope 5 and the second safety rope 13, outlets are arranged on the left side and the right side of the shell 1, and guide posts are arranged at the outlets.

For convenient hanging, the free ends of the first safety rope 5 and the second safety rope 13 are provided with hooks.

In order to place the ratchet wheel 11 to rotate reversely, a pawl matched with the ratchet wheel 11 is arranged on the shell 1.

When the device is used, the shell 1 is fixed, the shell 1 can be fixed on a steel structure of a wind power tower through the lifting hook 2 at the upper end of the shell 1, and then the first safety rope 5 and the second safety rope 13 are hung on a body of a constructor at the same time. The second safety rope 13 has a longer pre-extension length to provide a standby function, and the second safety rope 13 is finished so as not to affect the construction.

When in actual use, the first safety rope 5 mainly plays a role of protection, and the first safety rope 5 can be stretched and contracted slowly and freely but cannot be stretched rapidly.

When personnel fall accidentally, the first safety rope 5 can be pulled out fast at this moment, then the first reel 4 also can rotate fast, after the first reel 4 rotates fast, the afternoon device rotating simultaneously with the first reel 4 can receive the effect of a relatively large centrifugal force at this moment, the pin 8 in the limiting device is thrown out, after the pin 8 is thrown out, the pin 8 can be blocked by the limiting block when the first reel 4 rotates at this moment, thereby playing a role of blocking the state that the first reel 4 continues to rotate, and the first safety rope 5 stops extending at this moment, thereby playing the purpose of primary protection.

Meanwhile, after the pin 8 is blocked by the limiting block, the pin 8 simultaneously presses the pressing switch 14 positioned on the limiting block, once the pressing switch 14 is pressed down, the motor is triggered to start rotating, the motor rotates and then drives the second wire wheel 12 to rotate anticlockwise, and at the moment, the ratchet 11 can rotate anticlockwise under the cooperation of the pawl; after the second reel 12 rotates anticlockwise, the second safety rope 13 is gradually tightened, so that the dropped constructor is slowly pulled up, and the constructor can stand again. In addition, due to the design of the ratchet wheel 11, the second wire wheel 12 can be prevented from reversing, and the safety of construction staff is ensured.

After the constructor is restored to the safe position, the device can be replaced, disassembled, reset and the like.

The device plays two different insurance modes by arranging the two safety ropes, and the first safety rope 5 can realize overspeed automatic locking, so that timely interception is provided for unexpected falling of constructors, and the constructors are prevented from falling rapidly; the second safety rope 13 can start to reversely lift after judging that the personnel fall, so that the falling constructor can be pulled up and restored to the safety platform; provides self-rescue for constructors.
