Portable pneumatic roof bolter is suitable for bolting of roadway and coal roadway with rock hardness ≤ F5 ~ F8. It can not only drill bolt holes, but also stir and install resin coiling bolt. Outrigger bolter has the following characteristics:
1, small size, light weight, simple operation, easy maintenance.
2, gear type pneumatic motor, stable operation, high reliability.
3. Increased torque. It improves the applicability and greatly reduces the labor intensity of workers.
Because the ouch-type single bolter rig is completely under the control of people, all the unbalanced forces in the work must be overcome and controlled by people. In order to ensure the normal operation of the drilling rig, the form and strength of the unbalanced force produced by it must be limited to the range that people can bear. For example, weight eccentrization while the bolter is standing up, motor start up, speed regulation, and stop all produce unbalance forces that cause the control arm to swing. Therefore, on the one hand, we need to optimize the design of the bolter and adopt new materials to make the structure of the bolt compact, reduce the weight and improve the strength. In addition, in the design of the bolt drill for in-depth and detailed dynamic analysis and balance test, limit to reduce or eliminate the role of unbalanced force, so that people's operation in the work feel comfortable and will not feel laborious, fear.
