What is the main structure of the anchor drilling rig?
Anchor drilling RIGS play a very important role in various geological and hydropower station, railway and other projects. However, during the use of anchor drilling RIGS, we also need to maintain them. First of all, we need to understand the composition of anchor drilling RIGS. So, what is the main structure of the anchor drilling rig?
The main body of the anchor drilling rig is composed of components such as the drill pipe support equipment, power head, slide frame, and base. Now, let's take a detailed look at it for you

1. The support rod equipment and accessories are used for disassembling and joining drill pipes.
2. The power head is driven by a hydraulic motor and changes speed through gear transmission, driving the front drill pipe joint to rotate forward and backward. To reduce the vibration caused by the impact reaction force at the bottom of the hole during drilling, a rubber shock-absorbing pad is installed between the flange of the drill pipe joint and the flange of the output shaft. Behind the main shaft of the power head and below the hydraulic motor, there are joints for connecting the compressed air rubber hose. The compressed air is sent to the impactor through the power head and the drill pipe for operation, and the rock cuttings formed by the drilling are discharged to the ground.
3. The slide frame is the main component of the support rod equipment and the power head. It is the organization that ends the pressurization and lifting actions of the power head. The feed cylinder is located in the inner part of the slide frame. The piston rod pulls the chain through the push roller and the upper and lower guide wheel groups, and the chain transmits the force to the power head through the drag plate.
4. The base is in the form of a sled, equipped with a support cylinder on top. The drilling hole inclination Angle can be adjusted through a hydraulic control valve. Positioning holes are provided on the main beams on both sides of the base. When the drilling rig is in operation, the base should be reliably fixed to the ground fixed equipment through anchor bolts.
