1, Dual arm drilling working arm (drilling main arm) Two sets of independent hydraulic drilling arms are operated separately without interfering with each other, and can be operated synchronously or separately. The drilling arm is equipped with a multi degree of freedom hydraulic adjustment mechanism, with flexible and adjustable pitch, swing, and rotation angles, covering the entire cross-section area of the tunnel arch, side walls, and bottom plate, without any construction dead corners. The drilling arm comes with a parallel holding function, which enables precise drilling positioning and effective control of over excavation and under excavation; Suitable for anchor bolt holes, anchor bolt holes, advanced small conduit holes, locking foot anchor bolt drilling, stable drilling in soil layers, weathered rocks, and hard rocks. Thickened high-strength arm structure, resistant to impact and not easily deformed, with strong stability during long-term continuous construction, greatly improving drilling efficiency and reducing frequent equipment displacement. 2, Basket operation arm (manned lifting platform arm) Equipped with an independent hydraulic basket arm and a safety protection manned operation frame, it can be flexibly raised, lowered, and rotated. The basket guardrail has complete protection and sufficient operating space, providing a stable working platform for high-altitude processes. No additional scaffolding or mobile work carts are required. After drilling is completed, workers can complete auxiliary work such as anchor rod placement, anchor net laying, dangerous rock prying, charging, arch support installation, welding, and ventilation pipeline layout in the basket. The basket arm and drilling arm are independently controlled, allowing for simultaneous drilling and high-altitude auxiliary operations. The process seamlessly connects, saving equipment entry and transition waiting time and reducing safety hazards in high-altitude operations. 3, Core advantages of the complete arm frame combination 1. One machine for multiple purposes: combining drilling and high-altitude auxiliary operations into one, reducing the need for multiple equipment to enter the site and lowering construction costs; 2. Process collaboration: drilling arm construction support holes, synchronous matching support installation of basket arm, shortening the tunnel cycle footage construction period; 3. Space adaptation: The track chassis is matched with a foldable boom, allowing for smooth deployment in small section tunnels and stair step construction; 4. Convenient operation: Fully hydraulic proportional control, smooth movement, fast positioning, and single person cooperation with the team can carry out construction; 5. Safety upgrade: Standardized protective baskets replace simple scaffolding, improving high-altitude working conditions inside the tunnel. The whole machine arm system supports customized travel and lifting height according to needs, and is assembled and debugged at the source factory to adapt to various tunnel surrounding rock conditions. It is the preferred equipment for tunnel mechanized support.
