Basic Components Of Core Drilling Rig
The core drilling rig is composed of basic parts such as a rotary mechanism, a feeding mechanism, a lifting mechanism, a transmission mechanism, a control device and a machine base. Depending on the type of drilling rig, some core drilling rigs may also be equipped with control measuring instruments or other ancillary devices.
The rotary mechanism of the drilling rig is called a gyrator, which is used to drive the drilling tool to rotate so that the drill bit can continuously break rocks. There are three types of rotors for core drilling rigs: vertical shaft type, turntable type and mobile type. This is where the classification of core drilling rigs comes from.
The lifting mechanism is used to lift drilling tools, casing or other things. Most drilling rigs are specially equipped with a lifting mechanism, generally called a "lift", while some drilling rigs are not equipped with a lifting mechanism. For example, in mobile gyrator drilling rigs, the power head and the feed mechanism are used to realize the function of the lift.
The feeding mechanism is used to adjust and maintain the axial load on the drill bit at the bottom of the hole, and to feed the drilling tool according to the drilling speed of the drill bit to keep the drill bit drilling continuously.
The transmission mechanism is used to transmit power from the power machine of the drilling rig to the various working mechanisms of the drilling rig. There are three types of drilling rig power transmission: organic transmission, semi-hydraulic transmission, and full hydraulic transmission.
The control device is used to distribute power, adjust the movement speed of each working mechanism of the drilling rig, and change the movement direction and form of the working mechanism. The control mechanisms of mechanical transmission drilling rigs are generally set together with related components, while the control mechanisms of hydraulic transmission drilling rigs are mostly set together to become independent components, called control consoles.
Common Problems and Solutions for Using a Core Drilling Rig
Broken Bits
When drilling through the toughest materials like asphalt, concrete, and stone, bits can sometimes break during the process. If this happens, replacing the bit is easy just grab another one from your tool kit. It's also important to use lubricant like water while drilling, as this will help decrease friction and heat.
Jammed Bits
It can be slightly more challenging if your bit gets jammed in the material you’re working with but it isn’t impossible! The best way to release a jammed bit is to use a reverse drill mode on your machine. This will allow the bit to be released slowly and safely.
Overheating
It's important to keep an eye on the temperature of your core drilling rig while you're drilling too. If used too often or for too long, it can overheat and become dangerous. To ensure this doesn’t happen, make sure you give your machine time to rest between drills. This will help keep it cool as you work!
How to Clean Core Drilling Rig in the Correct Way?
There are a few cleaning fluids that you need to use to clean the core drilling rigs. These fluids are easily available. Firstly, these fluids are inserted into the pressure rig washer. This washer has the capacity to perform pressure washing. In this way, the hard and soft dirt eradicates from the drilling rig efficiently.
The rig washer has been designed specifically for rigs cleaning. You have to start the rig washer and direct it towards the core drill rig. It will work as a degreaser and solvent. As a degreaser, it will remove all the greases and dirt that cannot be cleaned with any other method. Moreover, the fluids present in this washer will remove the pesky deposits when applied with pressure.
