Rotary jet anchor drilling rig

Anchor drilling rig is an indispensable tool for anchor support in coal mines. The development of anchor support requires a large number of anchor hole drilling equipment to ensure it. It has outstanding advantages in improving the support effect, reducing the support cost, accelerating the speed of roadway formation, reducing the amount of auxiliary transportation, reducing labor intensity, and improving the utilization rate of the roadway section. It is suitable for small hole rock drilling, avoiding the powerful destructiveness brought by large rock drills, and it is safer to use.


Working principle of rotary jet anchor drilling rig


1. In layered rock formations, anchor rods suspend the lower unstable rock formations on the upper stable rock formations. The tensile force of the anchor rod comes from the suspended rock formation.
2. In thin rock formations without stable rock formations, after the anchor rod is installed safely, the clamping force of the anchor rod will increase the friction between layers. This friction force can prevent the rock from continuing to slide along the layer, thereby reducing several The rock formation is locked into a thicker rock formation by anchor bolts. The maximum bending stress and strain in this thick rock beam are inversely proportional to the square of the thickness of the beam. The thicker the integrated rock beam, the smaller the maximum bending stress and strain. At the same time, the strength of the bolt itself also increases the overall shear capacity of the beam.
