Technical Field
[0001] The utility model relates to the technical field of anti-falling safety ropes, in particular to a high-altitude anti-falling safety rope. Background Art
[0002] High altitude anti-fall safety rope is a kind of safety equipment used for high altitude operation, mainly used to prevent personnel from falling and causing injuries during high altitude operation. It is generally made of high-strength polyester fiber or nylon fiber, and has the characteristics of wear resistance, corrosion resistance and strong tensile resistance.
[0003] When a fall occurs, the safety rope will be quickly stretched and locked due to the high-speed fall, generating an impact force. This is due to the effect of Newton's first law. According to this law, an object will remain stationary or in a state of uniform linear motion without the action of an external force. When people fall from a height, they have a certain mass and speed. Once they are suddenly subjected to the resistance of the safety rope being stretched and locked, according to Newton's first law, their inertia causes them to continue moving forward, while the safety rope generates a reaction force pulling in the opposite direction. This results in a huge impact force that can easily cause harm to people. Summary of the invention

DETAILED DESCRIPTION
[0022] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a high-altitude anti-fall safety rope, including a shell 1 and a safety rope 2, an anti-fall mechanism 4 is arranged on the inner wall of the shell 1, and the anti-fall mechanism 4 includes: a connecting shaft 41, a volute spring 42, a connecting sleeve 43, a rotating shaft 44, a connecting spring 45, a pawl block 46, a sliding rod 47, and an inner ratchet ring 48, and a speed reduction mechanism 5 is arranged on the inner wall of the shell 1, and the speed reduction mechanism 5 includes: a circular groove 51, a fixed block 52, an annular spring 53, a sliding block 54, and a rotating rod 55.
[0023] The back of the sliding block 54 is slidably connected to the inner wall of the circular groove 51, so that the sliding block 54 slides along the inner wall of the circular groove 51 in an arc shape, and the front of the rotating rod 55 is rotatably connected to the inner wall of the housing 1, so that the rotating rod 55 can rotate stably.
[0024] A connecting shaft 41 is fixedly connected to the inner wall of the shell 1, one end of a spiral spring 42 is fixedly connected to the surface of the connecting shaft 41, the other end of the spiral spring 42 is fixedly connected to the inner wall of a connecting sleeve 43, a rotating shaft 44 is fixedly connected to the front of the connecting sleeve 43, one end of a connecting spring 45 is fixedly connected to the surface of the rotating shaft 44, the other end of the connecting spring 45 is fixedly connected to a ratchet block 46, a sliding rod 47 is fixedly connected to the surface of the ratchet block 46 close to the rotating shaft 44, the surface of the sliding rod 47 passes through the inner wall of the rotating shaft 44, and the surface of the sliding rod 47 is slidably connected to the inner wall of the rotating shaft 44, an inner ratchet ring 48 is fixedly connected to the inner wall of the shell 1, the hook 3 is fixed in a stable place, the safety rope 2 is tied to the body, and when the safety rope 2 falls down slowly normally, the safety rope 2 pulls the connecting sleeve 43 to rotate through the rotating rod 55, and the elastic force of the annular spring 53 makes the sliding rod 47 The movable block 54 and the rotating rod 55 will not rotate downward and be compressed. When a fall occurs, the connecting sleeve 43 rotates rapidly, and the connecting sleeve 43 drives the rotating shaft 44 to rotate rapidly. The rotating shaft 44 drives the sliding rod 47 and the pawl block 46 to rotate rapidly. The pawl block 46 stretches the connecting spring 45 under the action of centrifugal force and moves in the direction of the inner ratchet ring 48, so that the inner ratchet ring 48 is engaged with the pawl block 46, so that the connecting sleeve 43 can no longer rotate, and then the safety rope 2 is no longer released by the rotation of the connecting sleeve 43.

When a fall occurs, the connecting sleeve 43 rotates rapidly, and the connecting sleeve 43 drives the rotating shaft 44 to rotate rapidly, and the rotating shaft 44 drives the sliding rod 47 and the pawl block 46 to rotate rapidly. The pawl block 46 stretches the connecting spring 45 under the action of centrifugal force to move in the direction of the inner ratchet ring 48, so that the inner ratchet ring 48 is engaged with the pawl block 46, so that the connecting sleeve 43 can no longer rotate, and then the safety rope 2 is no longer released by the rotation of the connecting sleeve 43. At this time, the safety rope 2 is tightened, which plays a role in preventing a fall.
[0026] When the safety rope 2 is tightened, the tightened safety rope 2 pulls the rotating rod 55 and the sliding block 54, and the sliding block 54 squeezes the annular spring 53 and rotates on the inner wall of the circular slide groove 51, so that the tightened safety rope 2 will not stop releasing suddenly, but will be released a little bit under the resistance of the annular spring 53, avoiding the instantaneous huge impact force caused by the instantaneous stop of releasing the safety rope 2, thereby reducing the harm to personnel.
