Product Introduction

Product Introduction

Anchor support for coal tunnels has outstanding advantages in improving support effects, reducing support costs, accelerating tunneling speed, reducing auxiliary transportation volume, reducing labor intensity, and improving tunnel section utilization. Therefore, it has been widely valued and adopted by major coal-producing countries in the world, representing an important development direction of national coal tunnel support technology. In my country, anchor support technology for coal tunnels is one of the key research projects of the "Ninth Five-Year Plan" of the Coal Industry Bureau, and its development and promotion and application speed are getting faster and faster.

ZQJC Pneumatic Column Drilling Rig relies on the frame column to overcome the weight of the drilling rig and the counter-torque generated during work. The drilling rig is portable and has the characteristics of safety and explosion-proof, large torque, high speed, small mass, small size, high efficiency, simple structure, and easy maintenance. Therefore, this drilling rig has high working efficiency, good support quality, low labor intensity of workers, and low footage cost. It is one of the necessary equipment in the coal mining industry.

The machine is mainly used for detecting geological structures, coal seams, exploring and releasing water, gas, coal seam water injection, unloading pressure holes, drilling of anchor holes in tunnels, mixing of anchors and installation of nuts. It can also be used for mixing of resin anchors in rock tunnels and installation of nuts.

Working Principle

ZQJC Pneumatic Column Drilling Rig uses compressed air as power, controls the rotation and reversing of the rotator through the reversing valve, and the compressed air drives the gear motor to rotate. After two-stage reduction, it drives the main shaft to rotate, thereby driving the drilling tool to work; the jack is manually loaded to achieve top tightening and loosening; the reversing valve is used to control the feed mechanism to achieve the forward and backward movement of the drilling rig.

Performance Characteristics

High speed and high torque
Can be reversed in both directions
More reliable and durable
