​How much do you know about underground drilling?

Underground drilling vehicles are also known as rock-drilling trolleys. An underground drilling truck is a kind of machinery that can support the rock drill to drill the rock hole and walk with the help of various power. Do you know more about underground drilling？

How to make the drill bits of underground drilling durable?

1. The drill edge of the underground drilling rig is shortened to reduce feed resistance.

2. Take advantage of the opportunity to repair the cross edge and try to improve the negative front angle at the cross edge. Increasing the front angle of the underground drilling can reduce the cutting force and make the drilling light.

3. Use a larger rear corner. Reduce frictional resistance and make drilling light.

4. Reduce the top corner. Properly reducing the top corner of the underground drilling bit can increase the positive pressure of the cutting edge on the cutting surface, and the triangular belt drive is a truth.

5. Holes with poor aperture and roughness requirements can be properly maintained with slightly unbalanced edges. In this way, the hole diameter of the drilled hole is slightly larger, which can reduce the friction between the blade and the hole wall.

What structures are underground drilling?

The main working mechanism of underground drilling rigs is the drill arm. Underground drilling rigs have stacking, single-swing, duplex, and ring four types. Stacked and reservable drill arms are used for parallel and fan-hole drilling vehicles. A single-swing drill arm is used for fan-shaped underground drilling vehicles. Stacked drill arm in the underground drilling truck walking down, from vertical forward tilt 30 degrees, drilling by the landing cylinder rise, can be vertical back 5 degrees. When the side swing hydraulic cylinder is stretched, the upper shaft frame slides along the top column, causing the lower shaft of the arm to swing, achieving a shift in the center of the fan hole, and when the side swing hydraulic cylinder is fixed and the fan swinging hydraulic cylinder is telescopic. Make the thruster fan swing, when the fan swing cylinder length is fixed and the side swing hydraulic cylinder stretch, so that the arm drives the thruster to move, due to the upper shaft frame, the fan swing hydraulic cylinder, the arm, and the lower lug constitute a parallel four-link. To achieve underground drilling vehicle thruster translation.

What are the characteristics of underground drilling vehicles? 

As modern rock drilling production equipment, underground drilling vehicles should have the following conditions:

1) The performance of the drill arm and thruster can meet the requirements of the mine rock blasting process within the working area of the drilling vehicle;

2) Underground drilling vehicles should have higher productivity, less fault;

3) The equipment is flexible, durable, and energy-saving;

4) Reduce noise and dust hazards, safe production, improve working conditions;

5) Underground drilling vehicles should have a certain degree of automation.
