What are the advantages of full hydraulic tunnel drilling rig

Source:www.222ss.net      Release date: 2025-04-09
Full hydraulic tunnel drilling rig has the following advantages: 1. powerful Large torque: the full hydraulic system can provide large torque. Compared with the traditional mechanical tunnel drilling rig, it can more easily overcome the resistance of complex strata such as rocks in the drilling process, and is suitable for drilling in strata with various hardness.
Full hydraulic tunnel drilling rig has the following advantages:
1. powerful
       Large torque: the full hydraulic system can provide large torque. Compared with the traditional mechanical tunnel drilling rig, it can more easily overcome the resistance of complex strata such as rocks in the drilling process, and is suitable for drilling in strata with various hardness.
       Stepless adjustment of speed and torque: through the combination of variable oil pump and variable motor of the hydraulic system, the stepless adjustment of speed and torque can be realized in a wide range. The working parameters of the drill can be adjusted correctly according to different drilling processes and formation conditions, and the adaptability of the drill to various drilling needs is improved.
2. easy operation
       Full hydraulic control: the whole machine adopts full hydraulic control, with few and centralized operating handles. Workers can easily control the rotation, push, pull and other actions of the drill through the handle or button on the console, reducing the difficulty of operation and labor intensity of workers.
       Linkage control: the hydraulic linkage control is adopted for the rotation and push pull-out function, which can effectively avoid the drill pipe from sliding down during the construction process, and improve the safety and stability of the construction. At the same time, the chuck, gripper and oil cylinder of some drilling rigs can also be operated in linkage, realizing the automation of drilling, pulling and unloading drilling tools, and further improving the work efficiency.
3. adapt to complex environment
       Small volume and light weight: the integrated design or compact structural layout is adopted to make the drilling rig small in volume and light in weight, convenient for handling and moving in narrow tunnels such as coal mines, and able to adapt to different working spaces and complex roadway conditions.
       Crawler walking: equipped with crawler walking mechanism, it can work on uneven ground, has good mobility and climbing ability, can quickly reach the drilling position, and shorten the operation preparation time.
       Flexible angle adjustment: some full hydraulic tunnel drilling rigs adopt a rotating disc structure, which can realize ± 180 ° horizontal adjustment and -90 °~+90 ° pitch angle adjustment when the crawler chassis is not moving, which is convenient for hole layout in the mine roadway and meets the drilling requirements of different directions and angles.
4. safe and reliable
       Hydraulic protection device: the hydraulic system is usually equipped with complete protection devices, such as overflow valve and safety valve, which can prevent the system pressure from being too high, avoid damaging the equipment due to overload, and ensure the safety of operators.
       Equipped with safety system: it is equipped with hydraulic safety and automatic monitoring system, such as elastic vibration absorber, gravitational cleaner, hydraulic alarm device, automatic brake device, etc., which improves the reliability of the drilling rig, can timely find and deal with abnormal conditions in the drilling process, and ensure the safety of personnel and equipment.
       Remote operation: the centralized operation is carried out through the console, and the personnel can be away from the orifice for a certain distance, which reduces the injury to the operators caused by splashes and debris that may occur during the drilling process, and is conducive to personal safety.
5. high efficiency and energy saving
       Efficient drilling: it has high drilling efficiency and can quickly complete the drilling task. With its powerful power and flexible parameter adjustment ability, it can maintain good drilling speed in different formations, reduce drilling time and improve work efficiency.
       Energy saving of hydraulic system: the hydraulic system adopts double pump oil supply technology, with small power loss and high efficiency. According to the working state of the drilling rig, the hydraulic system can automatically adjust the output flow and pressure of the oil pump to achieve energy-saving operation and reduce energy consumption.
