Recently, the newly developed miniaturized ZYS123AG-FL full computer three-arm rock drilling trolley of Railway Construction Heavy Industry is suitable for the construction of a tunnel of Plateau railway. The drilling trolley is responsible for the excavation of the face of the hand, auxiliary charge, pipe shed, and anchor procedures. The average drilling speed of the trolley is 3.5 meters/min, the equipment failure rate is low, the excavation footage of each shift is more than 3.2 meters, and the drilling operation time is about 2.5 hours.

The ZYS123AG-FL all-computer three-arm drilling rig can solve the problem that the existing conventional three-arm drilling rig in the market is difficult to enter and exit the tunnel due to its relatively large size. The length of the machine is 15.7 meters, the width is 2.65 meters, and the wingspan boom structure is adopted. The maximum working height is 12.6 meters, the maximum working width is 15.8 meters, and the maximum drilling depth of a single pole is 4.6 meters. The truck is equipped with a full computer control system, with efficient and accurate drilling, anti-sticking drill, fault diagnosis, construction log recording and storage functions; At the same time, according to customer demand, the function has been expanded and upgraded, so that the three-arm drilling rig has the functions of anchor rod construction and exploration hole construction.

China Railway Construction Heavy Industry will continue to adhere to customer demand as the guide, carry out independent innovation, vigorously develop information and intelligent construction equipment, and contribute to the intelligent construction of tunnels in China. Editor/Wang Tian
