Tunnel Drilling Rig

1、 Company Profile Jining Tongzhao Machinery Co., Ltd. is located in Jining Engineering Machinery Industrial Park. For many years, it has been focusing on the research and development, manufacturing, and sales of tunnel support and rock drilling equipment. It integrates research and development, production, sales, and after-sales service, and has a complete independent production line and a professional hydraulic technology research and development team. All equipment completes multiple tests such as load, continuous drilling, and walking aging before leaving the factory, which complies with the construction standards of highway and railway tunnels. Its products cover various infrastructure projects across the country and are exported overseas in batches. It is a professional source manufacturer of tunnel anchor rods, pipe sheds, and advanced drilling equipment industrial control classrooms. 2、 Product positioning The Tongzhao Wheel type Tunnel Drilling Machine is a specialized fully hydraulic multifunctional support drilling machine for small and medium-sized tunnels. It adopts a tire walking chassis, balancing transition speed and flexible operation inside the tunnel. It is mainly used for the construction of urban tunnels, small section tunnels of national and provincial highways, water diversion tunnels, and mining tunnels. It can complete the full process drilling of anchor rods and cables, advanced pipe sheds, water and gas exploration, blasting holes, grouting reinforcement, etc. Compared with crawler models, it has faster transition, no damage to road surface paving, and efficient movement inside the tunnel. It is suitable for tunnel projects with tight schedules and frequent changing of working faces. 3、 Core product advantages 1. Wheeled chassis with outstanding advantages in maneuvering and transition The whole machine is equipped with thick solid engineering tires and comes with four-wheel independent hydraulic drive. It has fast walking speed, small turning radius, and flexible displacement of narrow palm surfaces inside the tunnel; After exiting the cave, one can transfer short distances on their own without the need for trailer transportation, saving transportation costs and waiting time; Equipped with four telescopic hydraulic support legs, the drilling operation is fully supported, and the whole machine is stable without shaking, balancing maneuverability and construction stability. 2. Dual power of oil and electricity, more environmentally friendly and energy-saving for tunnel construction Standard dual system of diesel and motor, oil and electricity: 45kW industrial motor is used for electrical conditions in the tunnel, with low noise and zero exhaust, improving the construction environment of closed tunnels; When there is no external power source, switch to diesel power, and both outdoor and newly built tunnels without power supply can continue to operate; The dual pump combined hydraulic system has a high power utilization rate, saving more than 20% of energy when drilling in the same rock formation. It is not easy to shut down at high temperatures during long-term continuous operation. 3. 360 ° all-round drilling arm, precise drilling without blind spots The drilling frame base is equipped with a fully hydraulic rotating disc, and the drilling arm can swing significantly left and right, with stepless angle adjustment up and down. It supports all-round construction of upward top holes, horizontal holes on the side walls, bottom low position holes, and inclined grouting holes; The lifting height can be customized according to needs and adapted to different cross-section tunnels; Thickened manganese steel telescopic slide, with strong guidance and high drilling verticality, effectively reduces the problems of deviation and jamming, and meets the high standard support construction requirements of high-speed tunnels.
