T23A Three-arm hydraulic drill jumbo PRODUCT FEATURE

 

jumbo
Also known as drilling trolley. It is a kind of rock drilling equipment constructed by drilling and blasting method for tunnels and underground projects. It can move and support multiple rock drills at the same time. It is mainly composed of rock drill, drilling arm (rock drill support, positioning and propulsion mechanism), steel structure frame, walking mechanism and other necessary auxiliary equipment, and equipment added according to engineering needs. When the drilling and blasting method is used to excavate the tunnel, it provides favorable conditions for the use of rock drilling trolleys, and the combination of rock drilling trolleys and ballast equipment can speed up construction, increase labor productivity, and improve labor conditions.
There are three types of trolley traveling mechanisms: track, track and tire type. Domestic rock drilling trolleys are more track and tire type. The rail type trolley body is generally gantry type, so it is often called gantry type rock drilling trolley. The upper part has a 2~3 layers of working platform, which can install multiple (up to 21 sets) rock drills; The lower part can pass ballasters, transport vehicles and other tools. This kind of trolley has a variety of functions such as drilling, charging, support, and measurement. It is developed to meet the needs of large-section tunnel construction, while overcoming the shortcomings of handheld rock drill drilling efficiency and being popularized and applied in railway tunnel and hydraulic tunnel construction. Install several drilling arms (used to install rock drills, generally 1~4 sets) on the car body to install self-made rock drilling machinery and equipment. The drill arm can be steered arbitrarily, and the rock drill can be run to any position and direction on the working face to drill holes (holes). The drilling parameters are more accurate, the drilling efficiency is high, and the working environment is greatly improved. The trolley power is divided into mechanical and hydraulic type, the latter is more used, the degree of automation is high, and the entire drilling (hole) program is controlled by computer. In the process of development, the ladder frame rock drilling trolley of the wind rock drill was initially adopted, and gradually replaced by the gantry type rock drilling trolley of the hydraulic rock drill. Tire type and crawler type rock drilling trolley is mainly driven by diesel engine, installed 2~6 high-speed rock drills, the turning radius of the car body is small, flexible and efficient, generally used for mine level tunnel excavation, can also be used for tunnel and underground engineering excavation. China Beijing-Guangzhou Railway Dayaoshan double-line tunnel construction, the four-arm hydraulic rock drilling trolley used, for diesel-driven special truck, operated by pneumatic hydraulics, the total length of the trolley is 15 meters, height 4.3 meters, width 3.5 meters, weight 42 tons, equipped with 4 hydraulic rock drills (see figure), its drilling speed is generally 50~100% higher than the wind, energy consumption is one-third of the wind, and can reduce noise; It can also adjust the amount of oil, pressure and piston stroke according to the hardness of the surrounding rock to improve the drilling efficiency. With the development of spray anchor support technology, the application range of full-section one-time excavation has been expanded, providing favorable conditions for the use of rock drilling trolleys, and the advent of new hydraulic rock drills and used in rock drilling trolleys will make the entire tunnel and underground engineering turn to a new stage of all-hydraulic large-scale mechanized construction.
