Uncovering the process flow of drilling and unloading drill pipe

What impresses the drill truck is the standard drill pipe. The drill pipe is one of the tools that must be used in professional drilling. The drill pipe is mainly used to transmit power to the drill bit and then follow the drill to enter the drilled part. . In the engineering drilling, the drilling and unloading requirements for the drill truck are very strict. Let's take a look at the drilling process of the drill truck.

Drilling rig mechanical mechanical unloading drilling rig drilling rod mechanism is composed of motor, reducer, upper and lower rod feeder, rod holder centering ring and so on. The entire mechanism is mounted on the rig. When the drilling vehicle is not working or is drilled with only one drilling machine drill rod, the delivery rod is in the withdrawal position, and the secondary drill rod is stored thereon.

The working process of drilling and unloading drill pipes

1. When the main drill pipe has been drilled into the blast hole and the auxiliary drill pipe needs to be connected, the main drill pipe is first caught by the clamp, and the reverse motor removes the main drill pipe.

2. The lifting motor is then actuated to lift the slewing gear and stop the lifting action when the pneumatic jaws of the slewing gear pass over the upper end face of the secondary drill rod.

3. Turn on the rod-sender motor and place the drilling machine's secondary drill pipe in the rotation center of the drilling tool.

4. Start the rotary air supply mechanism so that the gyrator rotates forward and slowly downwards, and the auxiliary drill pipe is screwed into the drill pipe joint of the rig.

5. Activate the rod holder and lift the bottom of the secondary drill rod. Then lift the secondary drill pipe up a certain distance so that its lower end leaves the bowl feeder bowl.

6. Return the rod feeder. Then start turning and lifting the motor, so that the sub drill pipe is turned down while rotating. After the main and sub drill pipes are screwed down, the supporting bar is put down to complete all the tasks of the bar.

How to remove Vice drill drilling vehicle

1. First raise the drilling tool and stop the drilling tool lifting until all the secondary drill rod retracts to the outside of the hole and the upper wrench of the main drill rod reaches the position of the chuck.

2. Hold the main drill pipe with a card. When the rotary motor is started and the gyrator is reversed, the upper part of the auxiliary drill rod can be detached from the main drill rod because the pneumatic claw catches the upper part of the auxiliary drill rod.

3. Support rod lifter. Raise the secondary drill rod a certain distance so that the lower end surface passes over the bowl feeder bowl.

4. Put the rig boom conveyor into the center of the slewing center, then lower the rig's secondary drill pipe and place it into the lower arm support bowl.

5. After the lower end of the secondary drill pipe is stuck in the bowl, reverse the gyrator and remove the secondary drill pipe from the gyrator.

6. Lower the lifter and return the lifter to the storage position. Lower the rotary air supply mechanism so that the gyrator is screwed to the main drill pipe.

7. Finally, lift the main drill pipe and impactor to the outside of the hole to complete all the unloading tasks.

With the continuous development of social economy, drilling technology has been widely used in society. However, due to various reasons, there are certain dangers in drilling operations. During the drilling process, the drill truck must be properly connected to the drill pipe. Only when the preparatory work is done well can the drilling project be carried out smoothly.
