Shank adapter

As a modern supporting rock drilling tool, the shank adapter is produced with the development of drilling technology and rock drilling conditions. In terms of rock drilling technology, when developing from shallow hole drilling to medium and deep hole drilling, due to the limitation of the working section, to obtain deeper rock holes, it is necessary to use coupling sleeves on the same axis of the drill rod. Connect multiple drill rods for drilling. The shank rod used in this rock drilling process is the prototype of the development of the shank adapter.

With the development of rock drilling equipment, the matching parts of the shank rod as a matching drill tool and the rock drill are more complicated, and the technical requirements for connection and cooperation are becoming more and more strict. To adapt to the changes, shank adapters of various structures have been produced.

Shank adapter classification

Common shank adapters are mainly divided into three categories: flange-type shank adapters, lug-type shank adapters, and spline adapters. The cross-section of the flange-type shank adapter is hexagonal, 22mm or 25mm for the inscribed circle diameter and 108mm or 159mm for length. It is manufactured by the forging process and is used for light rock drills. The lug-type shank adapter is used for inner-rotating medium-sized guide-type rock drills, and the diameter of the drill rod is 25mm or 32mm. The spline adapter is often used for heavy-duty guide-type external rotating rock drills with large torque, and the diameter of the drill rod is more than 38mm. It is often manufactured by a mechanical process.
