The working mechanism of KQG-150 mining DTH drilling rig adopts 360° rotation control, which can make upward holes, downward holes, slope holes, inclined holes and horizontal water detection holes or pre-split holes for local blasting. Its active deflection control Compared with traditional drilling rigs, the system's hole forming accuracy is particularly remarkable when working in inclined holes. The walking system adopts hydraulic motor drive, tire walking, soft start-stop control, hydraulic wet brake, large traction force, strong climbing ability, 360° in-situ steering, and small turning radius
4. Key technologies and innovations of underground DTH drilling rigs (1) Rock drilling system A) Propulsion guide rail: 1. It is treated with special technology and has high bending resistance, torsional strength, wear resistance and corrosion resistance. 2 The propulsion sliding pair adopts replaceable low friction pair, and the wear strip adopts replaceable self-lubricating wear strip, and the oil groove is processed on the high-strength and wear-resistant guide rail to form an oil film during the movement, thereby reducing wear and protecting The rail body is not subject to wear.
B) Receiving and unloading rod device: The unloading rod adopts active centering and automatic oil replenishment. The closed cavity is formed by design to ensure the active centering ability of the unloader seat. At the same time, in order to prevent the oil cylinder from leaking, the The influence of the centering ability is increased, and the automatic oil replenishment system is added to ensure the continuity and stability of the centering ability of the rod unloader.
(2) Control system A) Load-sensing system: Load-sensing technology uses pressure changes caused by load changes to adjust the pressure and flow of pumps or valves to meet the working needs of the system. The system is mainly composed of load-sensing variable displacement plunger pumps and load-sensing Control valve composition. The system can improve utilization efficiency, reduce system heat generation, and achieve the purpose of compact structure and energy saving of mechanical equipment.
B) CAN bus control: The program control system of CAN bus is adopted to simplify the circuit. Using remote wireless remote control, it is not affected and restrained by pipelines and lines, as well as the limitation of working space and conditions, and the operation is flexible. And the remote control box is equipped with a plug-in interface, which can be converted to wire control in extreme cases to ensure reliable operation.
5. Application scope of KQG-150 mining DTH drilling rig KQG-150 mining DTH drilling rig has compact structure, high ground clearance, good passing performance, hydraulic tires self-propelled, moving machine flexibly, and four supporting oil cylinders, The support of the two top support oil cylinders is stable and reliable, and the propeller adopts a large stroke compensation mechanism to ensure that the drilling rig can work normally on the ground of potholes and bosses. ° Rotation, it can drill various holes in the annular surface at any angle, with a diameter of φ76 ~ φ203mm and a depth of 100m, so it is especially suitable for drilling annular holes in underground stopes..
