A section containing an anchor

Product introduction of cutting section with anchor protection device

The cutting part with anchor protection device is replaced by the cutting part of the existing tunneling machine, without increasing the external dimension, and without changing other structures on the original tunneling machine.It can meet the functional requirements of tunneling, temporary support and anchoring, and greatly reduces the labor intensity.

The emergence of this product filled the blank of the coal machine industry, helped the coal mine reduce the cost, realized the reduction and improvement of human resources, safe and efficient continuous work of mechanization, and improved the overall technical level of domestic coal machine products.

The cutting part with anchor protection device is replaced by the cutting part of the existing tunneling machine, which is compared with the original cutting part, without increasing the contour size, affecting cutting performance, and without changing other structures on the original tunneling machine, so that the tunneling machine is upgraded to a multi-functional one with anchor protection.

The improved cutting section department adopts hydraulic power source of tunneling machine and is equipped with special cooler to prevent oil temperature from rising. Oil temperature does not affect cutting operation of tunneling machine and pump station can also be provided.

Under the condition of no driving machine, two rows of anchor bolt supporting operation can be realized (row spacing is less than or equal to 1.2 meters).

Reformable models: ebz150-ebz230, EBZ260.

The main features of the cutting section of the anchorage device

1. Rig torque: 300Nm; rig propulsion: 20KN; rotary speed: 460r/min.

2. The pre-tightening force can be directly applied to the bolt (the bolt generally requires the pre-tightening force of 120~150Nm).

3. Compared with conventional pneumatic anchor drill: the torque of traditional pneumatic anchor drill is small (up to 130Nm), there is no guide mechanism, and the hole-forming quality is poor;The drill rig of our company is equipped with large torque motor, with roof support mechanism, strong rigidity of guide slide frame mechanism, high drilling efficiency, good hole forming quality, good mixing effect of coils, and improved anchor protection strength.

4. Blocking function: the driving and anchor protection work can be closed to each other through hydraulic shutoff valve, that is, all actions of the driving machine can be fully locked during the anchor protection work.
