Knowledge of drilling equipment- Swivel structure and working principle

The swivel is hung on the hook through the lifting ring, the upper part is connected with the water hose through the gooseneck, and the lower part is connected to the square drill pipe to connect the drilling tool downhole. Faucets are mainly composed of goosenecks,

Punching pipe assembly, central pipe, shell, lifting ring and main shaft bearing, etc., the main function is to suspend the rotating drill pipe string, bear most or even all the weight of the drilling tool; High-pressure drilling fluid is delivered to the rotating drilling tool.

The structure of the hook and its working principle

The hook is an important equipment for lifting drilling tools, which is composed of hook body, rod, cylinder, lifting ring, thrust bearing and spring, the hook body can rotate, the hook mouth and the side hook have a locking device, and the hook has the function of buffering and damping. The big hook is combined with the traveling blocks as a whole, called the traveling hook, and is the main formation of current use.

The structure and working principle of the traveling block and the crane.

 The crane is the fixed pulley group that is installed at the top of the derrick, and the traveling block is the movable pulley group that reciprocates up and down inside the derrick, and is mainly composed of pulley, pulley shaft, bearing, bearing seat and support.
