The connecting ring, also known as the shackle, is a commonly used connecting device in mechanical engineering. Common shackles in engineering include European-style large bow shackles, European-style large DEE shackles, round head shackles, square head shackles, D-shaped shackles and other forms. In the rescue operation, the shackle is usually called the connecting ring, which is the necessary connection equipment between the wire rope, between the wire rope and the car body, between the wire rope and the pulley, and between the rigid traction frame and the car body. According to different uses, the form of connecting ring is also different, commonly used are D-shaped connecting ring, double D-shaped connecting ring, connecting sleeve and so on. In addition, the connecting ring also refers to a part of the fishing tackle, which is a small metal ring that connects the brain line and the main line.
3 What problems should be paid attention to when using shackles?
(1) Before using the shackle, carefully check its bearing capacity, whether the appearance is deformed or damaged, and whether the connection part is in good condition to prevent problems.
(2) The force direction of the shackle should be correct to prevent its lateral force.
(3) When connecting ropes or rings, one of them should be set on the horizontal pin and the other on the curved ring. It is not allowed to set it on the two straight sections of the shackle respectively.
(4) After the lifting operation is completed, remove it in time, insert the horizontal pin into the curved ring, and fasten the nut. It is strictly forbidden to drop the shackle from a high place to prevent its deformation and cause internal crack damage, and ensure that it is intact.
(5) The threaded part of the shackle should be lubricated regularly to make it well lubricated and not rusted.
(6) After use, store it in a dry place, pad it with wooden boards, and keep it properly.
(7) It is not allowed to use the shackle with the horizontal pin without thread. When it must be used, there must be safe and reliable measures to prevent the horizontal pin from slipping out and causing an accident
