The drum cutter can be installed on the excavator for construction, and the milling machine itself does not have a power system, and needs to rely on the hydraulic system of the excavator for power drive. Drum Cutters are divided into two types: horizontal and vertical.
These two types of milling machines can be installed on the front end of the stick of the excavator. The hydraulic power system of the excavator can be directly used to drive and control the work of the milling head. The operation is simple. , easy to install, flexible and efficient, and widely used.
(1) Wide range of milling and digging: different types of drum cutters can adapt to strata with different hardness, and concrete without steel bars or with a small amount of steel bars can also be milled.
(2) Reduce vibration and protect the environment: it can replace blasting construction, has low vibration and noise, and can better protect the environment.
(3) Accurate control of the excavation surface: it can better solve the problems of over-excavation and under-excavation, accurately trim the excavation contour, and help reduce costs.
(4) Safety: the use of drum cutters in soft rock or broken rock formations can replace manual excavation, so that construction personnel can leave the working face and reduce the danger of falling blocks and collapses encountered by construction personnel in front of them during the excavation process , to improve the safety of tunnel construction
(5) Simple Structure, easy to use, and relatively low price: it can be installed on any existing excavator without special supporting equipment. Compared with tunnels, shields and other machinery, the equipment is cheap.
The section diameter of the section tunnel is only 8m, making it difficult for large excavators to operate. After comprehensive comparison and analysis, this project can adopt the milling and excavation method and the crushing and excavation method of small and medium-sized excavators.
Through the investigation and understanding of the market, the tamping and grinding equipment is selected to excavate the interval tunnel.
There are two basic types of compacting and excavating machines: Horizontal drum cutters and Vertical drum cutters; which can be assembled on excavators ranging from 3-70t respectively.
Drum Cutter is a large-scale manipulator-operated equipment, which is widely used in various resource mining and industrial construction fields such as coal mine exploration, tunnel excavation, and road milling.
The tunneling planning of the drum cutter refers to generating the required action sequence and motion path from the initial state to the target state according to the requirements of the tunneling path of the drum cutter and under the condition of meeting various technological indicators.
A good planning method can not only increase the service life of the milling machine, reduce energy consumption, and save costs, but also improve the speed, stability, reliability and accuracy of the milling machine manipulator control system. However, for multi-degree-of-freedom milling machines, it is a very complicated problem to design an effective tunnel planning algorithm under performance indicators such as speed, acceleration, and motion time.
