Mining Rock Bolt Domed Plate
The anchor bolt plate is one of the parts of the pipe joint anchor. The material adopts welding ring and rolling head to make rod body, cutting around the ring to make retaining ring, and cutting board, punching and punching to make pallet. There are many types of anchor bolt plates, the main ones commonly used in mines are butterfly plates and flat plates. The bearing effect of butterfly plates is better than that of flat plates.
As an important part of the bolt support system, the performance of the bolt plate directly affects the supporting effect of the bolt. The function of plate is to transfer the thrust generated by the tightening torque of the nut to the top lining to generate initial anchoring force. At the same time, it transmits the pressure of the top lining of the roadway to the bolt, which generates working resistance, strengthens the surrounding rock together, and prevents the top lining of the roadway displacement.
