DL1 Hydraulic Long hole Drill Rig

DL1 Hydraulic Long hole drill rig, specially developed for small-drift mining to do the long-hole production, especially in 3m or smaller tunnel, the advantages is unique. The feeder can be placed flat to facilitate the transition in small tunnel. The cantilever structure is designed to operate at the section for easy operation and positioning, and is suitable for parallel and fan-shaped hole rock drilling operations.

Remarks: Due to the continuous upgrading of products, the company reserves the right of final interpretation.

DL1 Hydraulic Long hole Drill rig Equipment construction View

Overall Dimension/main view

Lightweight and compact, fast, stable and high efficient, it is assembled with internationally renowned brand components, hydraulically controlled full wet brake system, simple maintenance, safe, reliable, direct, and low failure.

Rugged propulsion beam

Heavy-duty propulsion beam extruded from aluminium alloy It has high bending and torsional strength, and has a long service life; the surface of the propelling beam is covered with stainless steel skin, and the moving parts are made of PTFE (solid lubricating block) wear-resistant lining, which does not need to be lubricated. Different drill pipe lengths (propulsion beam lengths) are selected according to different drift sizes, and upper and lower top oil cylinders are provided to make the positioning of the propulsion beam more stable .

High power hydraulic rock drill

In order to consider the rock drilling performance of the surrounding rock structure, our company provides a variety of international well-known brand rock drill configuration schemes for users to choose, all of which are high-power rock drills. Extend the life of drilling tools, higher production efficiency, and lower rock drilling costs.

◆The rate of rock drilling is faster than other rock drills, especially when the surrounding rock is hard, the rock drilling efficiency is higher.

◆It adopts high-pressure high-frequency impact design, which has stronger explosive force and is suitable for working conditions with high hardness of surrounding rock.

◆Durable parts: The moving parts of the hydraulic rock drill have high lubrication level and sufficient aerosol lubrication; at the same time, the end face is equipped with oil and gas to block foreign objects outside the machine body. The product is not prone to corrosion and rust, and has a long service life.

◆Adopt double buffer design to prolong the service life of piston and drill.

Robust cantilever boom can be rotated, pitched and telescopic

Cantilever telescopic drill boom is stable, accurate in positioning, and can be rotated. It can be used for medium and deep hole rock drilling. It is suitable for drilling vertical, inclined annular and fan-shaped blasting holes. Adopt reliable screw cylinder with high torque and high load capacity, no position offset, ultra-compact, good anti-pollution ability and durable.

Time-saving, easy to operate, no manual calibration is required, and simple to operate.

◆Heavy-duty drill boom design, solid and reliable structure, square section design of drill boom, stronger bearing capacity than traditional square drill boom, all joint pins are expansion-fixed to avoid loosening, and wear-resistant bushings are embedded inside.

◆The boom is telescopic, because the machine body is narrow and the ceiling can be raised and lowered, and the telescopic boom is matched to make it suitable for a wide range of operations.

Digital display angle positioning - the digital display angle of the advancing beam is more intuitive.

The digital display of the positioning angle function of the advancing beam makes the deviation rate small, the drilling positioning accurate and fast, and the qualification rate is high.

Safe, efficient and stable hydraulic system control

◆Use the American Sao Danfoss hydraulic control system to directly control the rock drilling system, the Danfoss plunger pump is the preferred pump for large-flow small and medium-sized trolleys, with reliable quality and long service life, and the domestic after-sales service is very complete.

◆Equipped with automatic anti-jamming function, service brake failure alarm, parking brake failure warning, electromagnetic pump aerosol lubrication oil shortage shutdown protection and other functions.

◆There are water and gas switching valves, which can be switched at any time according to demand.

◆Equipped with a multi-faceted safety alarm system, the usability and safety are very high, and it has alarm prompt functions such as low fuel level, high water temperature, and high hydraulic oil temperature.

Safe and Powerful Traveling Undercarriage

Adopting the design concept of narrow fuselage and short drill arm, mainly considering the adaptability to the operation of various specifications and section sizes, especially when the rock tunnel or the walking tunnel is moving in the small tunnel, the narrow fuselage and small turning radius are used to facilitate flexible walking in the small tunnel.

◆It can be equipped with a variety of Deutz/Yanmar diesel engines for walking, four-wheel drive, tire walking, and climbing ability >14.

◆The four-wheel-drive wheel motor is used for driving, and the pump and motor are directly controlled by the control valve, which is more efficient, direct, less faulty and simple in structure than the bridge.

◆Equipped with emergency stop button switch, the rear axle swing angle is 6°to adapt to uneven road surface and improve stability.

◆The service brake adopts hydraulic control, hydrostatic transmission system, and wet braking, which is safe and efficient with low failure.

DL1 (CYTC76) is a compact and flexible electro-hydraulic production drill rig for long hole operations in underground mine production. The compact design is specially developed for long hole rock drilling in small roadway mining. Various deep hole arrangements such as vertical, inclined, parallel and fan-shaped work. The machine adopts full hydraulic drive rock drilling, which can drill 64-76-89mm hole diameter, and the rock drilling depth is 25 meters at a time. The strong and stable long hole drilling arm is equipped with two jacks, which makes the positioning and support of the propulsion beam stable and ensures high quality drilling. Diesel engine four-wheel drive tire chassis walking, climbing <14°, suitable for working tunnel size 2.8x2.8~4.3x4.3m.

·Hydraulic control lift cab

It meets the requirements of FOPS (falling object impact), and the hydraulic cylinder controls the lift to adapt to the passage of short and small drift.

·Hydraulic automatic retractable
