Common types and working principles of engineering drilling RIGS

Common types and working principles of engineering drilling RIGS

Engineering drilling rig refers to the special machinery used in civil engineering, mining engineering, construction engineering and other fields

The main function of the equipment is drilling.

Common types of engineering drilling RIGS can be divided into the following categories:

1. Hand-held drill: Hand-held drill is usually composed of a motor, drill bit and drill clamp, which can be used for drilling

Hole, tapping, reaming and other operations. Its working principle is to rotate the drill bit through the motor, and then

Implements drilling operations.

2. Fixed rig: Fixed rig is generally composed of main engine, support, cylinder, conveyor and other parts

Make up. Mainly used in geotechnical drilling, foundation treatment, underground mining and other projects. Its working principle is passable

Overdrive mechanism (such as hydraulic cylinder) makes the drill pipe rotate and move up and down to complete the drilling operation.

3. Geological drilling rig: Geological drilling rig is mainly used in geological exploration, oil exploration and other fields. Its structure

Generally includes the main engine, plunger type hydraulic motor, turntable, transmission system and so on. It works by fluid

The press system provides power to drive the drill pipe to rotate and press down, enabling drilling operations.

4. Water well drilling rig: water well drilling rig is mainly used for drilling Wells, coal mine roadway and other underground space. its

The structure includes main engine, drive system, drill pipe and so on. The working principle is through a drive system (such as fluid

Pressure system) provides power to drive the drill pipe to rotate and press down to complete the drilling operation.

5. Vehicle drilling rig: Vehicle drilling rig is mainly used for road construction, bridge construction and other projects. Its design

It is generally mobile for easy operation at different work locations. It works like any other rig,

The drill pipe is rotated and pushed down by the power system.

6. Rock drill: Rock drill is suitable for rock exploration, blasting operations, etc. Its structure includes a car

Frame, assembly, shaft, etc. The working principle is to provide power and drive through electric motor or hydraulic system

Define the shape of the drill bit for drilling.

7. Pile drilling machine: Pile drilling machine is mainly used for pile foundation construction of construction projects, and is used for group rapid drilling

Special equipment for holes. It can be loaded on the excavator or loader as required to improve work efficiency.

The working principle is similar to that of other drilling RIGS, and the drill pipe is driven by a drive system to rotate and press down.

In summary, there are many types of engineering drilling RIGS, and the specific selection should be determined according to different engineering needs

Agreed. The working principle is basically similar, mainly through the power system to drive the drill pipe to rotate and press down,

Thus drilling operation is realized.
