Core drilling equipment application range
Fully hydraulic core drilling machines are suitable for metallic or nonmetallic solid mineral resources, engineering geology, coal bed methane, natural gas, hydrological water wells, geothermal wells, and ventilation for exploration and drainage of mine tunnels. Hydraulic core drills can also be used for engineering rescue.
Structure of concrete hole drilling machine
The full hydraulic core drilling rig is mainly composed of a power system, hydraulic system, rotary mechanism, feeding mechanism, elevating mechanism, control system, and other auxiliary parts. Among them, the hydraulic system is the core part of the drilling rig, which converts mechanical energy into hydraulic energy through the hydraulic pump, and then drives each working part of the drilling rig through the hydraulic transmission device.
Working principle of full hydraulic core drilling rig
The working principle of a fully hydraulic core drilling machine is mainly based on hydraulic transmission technology. In the drilling process, the power system (such as a motor or diesel engine) drives the hydraulic pump, which conveys the hydraulic oil to each hydraulic actuating element (such as hydraulic cylinder, hydraulic motor, etc.), and realizes the rotary, feeding and lifting actions of the drilling rig through the hydraulic transmission device. At the same time, the control system monitors and adjusts the parameters of the drilling rig in real-time to ensure the stable operation and high efficiency of the drilling rig.
Workflow of fully hydraulic core drilling rig
- Preparation. First of all, level the ground, level the equipment itself, adjust the angle of the mast according to the design requirements, dig a good mud pool, connect the mud pump, and do other preparatory work.
- Drilling casing. Drilling construction needs to put the casing in place in advance, the specific requirements are casing into the bedrock.
- Formal drilling. Lift and connect the double pipe drilling tool assembly to the top of the power head, start the mud pump, and start drilling formally.
- Grab the inner pipe to take out the core. After the completion of the back to the footage, the core in the inner tube is full. At this time it is necessary to use a hydraulic winch, with a wire rope to salvage the salvage device down into the drill pipe. The inner pipe is then fished out, after which the core is removed from the inner pipe.
- Place the core and make records.
- Measure the slope. According to the design requirements, generally after drilling to a certain number of meters, the inclination angle of the hole will be measured to ensure that the hole meets the requirements of the inclination angle.
- Collect the hole and lift the drill, then seal the hole. After completing all the collection work, the drill pipe and casing in the hole can be raised. After that, cement is utilized to seal the hole.
5 advantages of a fully hydraulic core drilling rig
- Due to the detachable structure, the hydraulic core drilling machine is easier to transport. It is modular in design and easy to install.
- This machine has powerful transmission power and high stability of hydraulic power. 3.
- Stepless speed regulation is available. The hydraulic core drilling rig runs stably and has a wide range of speed regulations. It can also realize high torque at low speed.
- With the combination of mechanical gear shifting and hydraulic speed control, the fully hydraulic core drill rig can realize step-less speed change between 0 and 1200 rpm. It also has a digital display.
- Our hydraulic core drilling rigs are overload-protected.
Why use a fully hydraulic core drilling rig?
Most foreign developed countries have entered the era of fully hydraulic core drilling machines, and some developing countries have also begun to vigorously promote the application of fully hydraulic core drilling rigs. Especially some developing countries have a growing demand for mineral resources, so the demand for drilling equipment is increasing day by day.
In the international market, from 2004, the global mineral exploration market began to get out of the trough at the end of the last century and go up year by year, and the investment in mineral exploration continues to grow. Therefore, people’s demand for drilling equipment continues to grow, core drilling rig is the key equipment for geological exploration, and market demand also continues to grow with the mineral exploration investment. This indicates that fully hydraulic core drilling rigs have become the mainstream trend in the industry.
