Rock breaking by the hob often requires a large rock breaking load, and the weight of a single hob is also particularly large, for example, the maximum design load of a widely-used 17' hob can reach 20 tons generally, and the weight of a single hob can even exceed 200 kg. In the process of excavating a tunnel by using the excavator, particularly when a hard rock stratum is excavated, the abrasion of a cutter is fast, frequent cutter changing is often needed, the conventional cutter changing process of the existing rock excavator is shown in fig. 12, an operator needs to hoist a heavy cutter to the lower part of the inner side of a cutter head from the outer side of a host through a main drive center region, the cutter changing personnel in the cutter head needs to change the cutter in a very narrow space, the cutter conveying path is complex (such as a zigzag conveying path) and the conveying distance is long, so that the labor intensity of cutter changing operation of the excavator is high, the cutter changing time is long, the operation safety risk is high, and the cutter changing operation is a main reason for causing long-time shutdown and construction stop of the excavator. Therefore, how to improve the tool changing efficiency and the safety are outstanding problems faced in the field of heading machines and are also targets continuously pursued in the field.
The existing method for improving the tool changing efficiency mainly comprises a normal pressure tool changing technology and a manipulator tool changing technology. The normal pressure tool changing is mainly used for a large-diameter slurry shield machine (with the general diameter of more than 12 m), the principle is that a cutter head is designed to be of a hollow structure capable of accommodating tool changing operators and tools, the normal pressure tool and a cutter holder are installed, and the problem of safe tool changing under the high water pressure condition of the shield machine is mainly solved. If the domestic patent "a ordinary pressure tool changing blade disc", patent number CN106555594B discloses an ordinary pressure blade disc scheme of installing ordinary pressure cutter on the spoke that has box style structure, can realize personnel's ordinary pressure tool changing operation under the high atmospheric pressure environment, but this scheme can't be applied to TBM blade disc and minor diameter entry driving machine. The manipulator tool changing technology is that a special manipulator is adopted to transport a tool into a cutter head and complete installation, and the tool changing process does not need personnel participation, for example, in the domestic patent, "a slurry shield machine auxiliary tool changing device and a use method thereof", patent No. CN2016101064582.6, but the tool changing systems are still large in size, complex in structure and high in cost, and currently, no practical available technology exists.
