Description of ZTMC40/70 Drilling Rig
1, simple up and down device
The simple up and down device can adjust the horizontal height of anchor cable hole easily.
Wear resisting Nylon plate can prevent guide track from wearing when power head operates.
2, reliable power head
Cycloidal gear reductor and electric motor forms power head. The power and torque transmit is stable and big.
The air packet is the air source inlet of impactor, in the meanwhile it can reduce the impact of power head from drilling rod.
3, reliable propulsion device
This device adopts hydro-cylinder and chain propulsion with compact structure, big lifting force and good stability.
4, centralized control system
Electric operating and rock drilling work are both centralized controled. It is convenience and fast.
The unidirection throttle valve can adjust feeding speed at any time.
Propulsion reducing valve hand wheel can adjust propulsion force as per different working situation.
5. convenient up and down adjust mechanism
The up and down hydro-cylinder can adjust the angle of guide rail fast to satisfy drilling requirements from different angles.
The compensation hydro-cylinder can guarantee the guide rail to stand vertically on the ground when making vertical drilling.
6. strong power head
7.power components
3-phase asynchronous electric motor and double connect gear oil pump provide power for drillng rig.
8. centralized control bench
The control bench far from drilling rig can protect the safety of operator.
The centralized control metal stick makes the controlling of drilling rig easy and convenience.
Advanced hydraulic system can realize drilling rig rotating and feeding fast.
9. reliable propulsion device
It adopts hydro-cylinder feeding pattern with compact structure, big lifting force and good stability
10. compact hydraulic station
This hydraulic station provides transmit media for hydraulic system.
The radiator can reduce the oil temperature efficiently to avoid hydraulic oil from changing to low viscosity or destroyed because of the very high temperature of oil.
The electric control box can protect the electric motor to operate safely.
