DW2-50 double-arm (hydraulic) rock drill truck

DW2-50 double-arm rock drilling rig is a double-arm mining hydraulic TBM drilling rig, designed and developed for small and medium-sized roadway drilling. The machine is equipped with 2 sets of independent fully hydraulic-driven rock drilling systems, which do not affect each other. It is equipped with a high-power rock drill with a rock drilling speed of up to 0.8-2.5 meters/min. It is suitable for a wide range of surrounding rock grades and is equipped with a fully hydraulic leveling retractable drill arm, which is suitable for roadway operations below 8.5m wide x 6.8m high, diesel engine four-wheel drive tire type external chassis, fully wet type The axle undercarriage system has a dual-way brake control system with high safety and reliability, a climbing ability of 14° (25%), and a walking speed of 16km/h.

Applicable range

Suitable for high-speed high speed railways, water conservancy and hydropower projects, and national defense tunnels below 8.5x6.8m.

Main features

High-efficiency and high-power hydraulic rock drill

● In order to consider the rock drilling properties of the surrounding rock structure, a variety of rock drill configuration options are provided for users to choose from. The standard configuration is Worth A18D/L (optional A22L/D), or other types of rock drills are selected. Different rock drills have different rock drilling costs, which makes it possible to obtain higher rock drilling rates, shorten cycle operation time, extend drilling tool life, higher production efficiency, and lower rock drilling costs.

Hydraulic system

● The hydraulic control system of the internationally renowned brand plunger pump is used to directly control the rock drilling system, which has reliable quality and long service life.

● Equipped with automatic anti-jamming function, brake failure warning and other protection functions.

● The hydraulic fuel tank is equipped with a fuel pump to facilitate equipment maintenance, and the fuel tank is equipped with a sensor to stop and protect when the oil level is low.;

● The rock drilling control is controlled by a proportional valve of an electromagnetic pump, which makes the rock drilling system stable and safe.

● The hydraulic tubing adopts multi-layer tubing of well-known international or domestic brands such as Horse brand, and the tubing joints adopt major brands such as Sugeqiang, and most hydraulic pipelines have safety valves to reduce oil leakage from the quality of the components and the source of the hydraulic system.

● There is a multi-faceted safety alarm system, which is extremely useful and safe. If the fuel level is too low, the water temperature is too high, and the hydraulic oil temperature is too high, it will have an alarm prompt or automatic shutdown.

● Fully automatic anti-jamming and automatic de-drilling functions protect the rock drill and drilling tools from damage, and are equipped with collision valves. When the rock drilling is completed, the automatic de-drilling rod protects the rock drill.

Wear-resistant rock drilling propulsion

● The propulsion beam made of aluminum alloy is wrapped in stainless steel protective skin, and polyurethane (solid lubricating block) wear-resistant liner is used between the movement gaps. It is light in weight and has high bending and torsional strength. It has a long service life. It can be equipped with drilling tools of different specifications to meet different drilling needs. When drilling large-caliber holes, it is equipped with a one-key switch protection function for large and small holes.

Fully hydraulic flat-acting telescopic drill arm

● The new double-triangle hydraulic leveling drill boom is adopted to increase the telescopic distance, the operating range is wider and higher, and the crank arm supports the propulsion assembly to make the grooving positioning field of view better to operate.

● Each pin shaft on the drill arm adopts an expansion shaft design to avoid the possibility of loosening, safe, easy to disassemble, and retractable. The 1500mm secondary compensation increases the punching range, and the one-time parking meets the full-section rock drilling operation without mobile equipment.

Safe and efficient electronic control system

● The electrical system adopts Schneider Electric control system, which is safe and reliable.

● With impact timing, digital voltage/current display meter/phase sequence indication, leakage shutdown protection, overload, overcurrent, short circuit and other shutdown protection.

● Equipped with an emergency stop switch button.

● Equipped with speakers, signal lights, and driving warning devices.

Hydraulic automatic winding cable

● The cable reel is a hydraulic automatic cable coiling system, which is equipped with a lower cable tension reversing valve group to control the receiving and discharging cable, reduce cable friction and extend the service life of the cable. The length of the flame-retardant cable on the vehicle is 90 meters.

Optional device

● Rock drill

● Centralized lubrication system

● Butter machine, butter reel

● Water pipe reel

● Closed cab

● DANA front and rear axles

● Plateau type

● Automatic fire extinguishing system

● Preheating system in alpine areas

Safe and efficient walking undercarriage system

● Dedicated wet axle and dual-way braking system to ensure driving safety and reliability, chassis articulated frame, hydraulic power steering, four-wheel drive, flexible angle ±40° transition, fast walking speed and good stability.

● Equipped with driving brake, parking brake, emergency parking, fully enclosed wet axle, dual brake system hydraulic control of driving brake, spring release, safe braking effect, simple maintenance, reliable, direct, low failure.
