The Q/GM312B automatic anchor feeding arch-anchor-grouting combined operation trolley independently developed by our company features functions such as arch erection, anchor hole drilling, automatic anchor feeding, prestress application, and grout mixing and injection. Without requiring the equipment to leave the site, it can complete the three processes of arch erection, anchor installation, and grouting simultaneously, improving work efficiency by more than 50% compared to traditional methods, significantly reducing the number of construction personnel, and greatly enhancing the safety index.
Equipment Advanced Features
Construction methods: Suitable for various operation modes including three-bench, two-bench, micro-bench, and full-face methods;
Three major processes: Arch erection, anchor installation, and grouting;
Eight major functions: Charging, arch erection, anchor mesh welding, foot-lock anchor installation, systematic anchor installation, advanced pipe shed/duct installation, high-pressure grouting, and prestress application.
Structural Characteristics
Integrated rigid engineering chassis, four-wheel drive, dual driving modes of local and remote control, electric operation with diesel emergency power, all three arms featuring rotary folding and telescopic structures, with the working radius of the side arms greatly increased compared to other products. The three-arm, three-gripper structure is equipped with a high-power rock drilling system, with a maximum single drilling depth of 4.5m, capable of installing 4.5m drill rods. It is equipped with dual automatic anchor feeding mechanisms, capable of installing various specifications of anchors, and is fitted with a high-pressure grout mixing and injection pump, enabling grouting operations with multiple types of grout, with a grout mixing and injection capacity of up to 4 cubic meters per hour.
Significant Advantages
1. Green: Low energy consumption, zero emissions;
2. Efficient: Only two operators and one auxiliary worker are required for the machine; no vehicle movement is needed during the construction process, saving 2 hours of conversion time per cycle; arch erection takes only 50 minutes; equipped with a high-power hydraulic rock drill with a maximum power of 22kW and a drilling speed of 2m/min; drilling diameter ranges from 41-110mm, suitable for anchor holes, advanced small ducts (42mm), advanced medium pipe sheds (60, 76mm), and advanced large pipe sheds (108mm); the left and right automatic anchor feeding systems can simultaneously perform foot-lock anchor and systematic anchor installation, with each side capable of carrying 10 anchors, totaling 20 anchors on both sides. The large-capacity grout pump delivers 4m³/h with dual-channel grouting, doubling efficiency;
3. Intelligent: Multi-process linkage, remote wireless control, automatic data collection and upload;
4. Safe: Remote control ensures construction safety, all three major processes are completed in one pass, equipped with protective facilities such as emergency stop, reducing labor requirements and alleviating labor intensity.
