Anchor rod trolley is a self moving equipment that drills anchor rod holes in the roof or side walls of underground tunnels and completes partial or complete the installation of anchor rods. With the popularization and development of anchor rod support operations in underground engineering such as mining tunnels and tunnels, anchor rod trolleys have become an indispensable and important equipment in these projects. Their high efficiency, intelligence, multifunctionality, and flexibility provide strong support for modern tunnel construction.

　　1、 Main characteristics of anchor rod trolley

　　Efficiency: The anchor rod trolley can automate the anchor rod support operation, greatly reducing the labor intensity of workers and improving construction efficiency.

　　Intelligence: Modern anchor rod trolleys often use computer-controlled trolley control systems, which can achieve precise positioning and automated operations, improving construction quality and consistency.

　　Multifunctionality: The anchor rod trolley not only has drilling function, but also can complete processes such as grouting and installing anchor rods, realizing the full process mechanization of anchor rod support operation.

　　Flexibility: The design of the anchor rod trolley is flexible and can adapt to the requirements of anchor rod support operations at different heights and angles.

　　2、 Advantages of anchor rod trolley

　　Improve construction efficiency: The anchor rod trolley can automate the anchor rod support operation, greatly shortening the construction period.

　　Improving construction quality: Through a computer-controlled trolley control system, precise positioning and automated operations can be achieved, improving construction quality and consistency.

　　Reduce labor intensity: The application of anchor rod trolleys reduces the labor intensity of workers and improves construction safety.

　　Enhanced adaptability: The design of the anchor rod trolley is flexible and can adapt to the needs of anchor rod support operations at different heights and angles, improving the versatility and adaptability of the equipment.

　　3、 Types of anchor rod trolleys

　　Anchor rod trolleys can be classified into various types based on their structure and function, such as tower type anchor rod trolleys, thruster type anchor rod trolleys, and rotary type anchor rod trolleys. These different types of anchor rod trolleys each have their own characteristics and application scenarios.

　　4、 Application scenarios of anchor rod trolley

　　Tower type anchor rod trolley: composed of drilling arm, hydraulic rock drill, walking mechanism, and control system, etc. The hydraulic rock drill is installed at the top of the drilling arm, and the drilling of anchor rod holes is achieved through the lifting and lowering of the drilling arm.

　　Propeller type anchor rod trolley: Similar to tower type anchor rod trolley, but its hydraulic rock drill is propelled by a thruster, which can swing back, forth, left, and right at a certain angle to meet the needs of different hole positions.

　　Rotating anchor rod trolley: using a rotating frame instead of a propeller, the rotating frame can drill anchor rod holes and install anchor rods, with higher operational efficiency.

　　Anchor rod trolleys are widely used in various underground engineering constructions such as tunnel excavation and underground factory building excavation. It can efficiently perform tasks such as blasting drilling, anchor drilling, automatic clamping and pushing of anchor rods, and automatic grouting, becoming an indispensable equipment in underground engineering.
