Abstract

The invention discloses a cutter changing-manipulator for a disc-shaped hobbing cutter of a shield machine and a using method thereof. The manipulator comprises a box body. Hydraulic cylinder supporting seats are arranged on the upper and lower end faces of the box body. Manipulator finger supporting seats are arranged at the front end of the box body. Manipulator fingers are hinged to the manipulator finger supporting seats in a longitudinal symmetry mode. One ends of hydraulic cylinders are hinged to the hydraulic cylinder supporting seats, and the other ends of the hydraulic cylinders are hinged to the manipulator fingers. Through holes are formed in a front box plate and a rear box plate of the box body. A disc-shaped hobbing cutter disassembling and assembling block is inserted in the through holes and penetrates through the box body. Each pair of manipulator fingers are driven through a corresponding hydraulic cylinder, so that good synchronicity of the manipulator fingers is guaranteed; the manipulator fingers are simple in structure, easy to machine and high in practicability; the box body is designed as an I shape and has the good mechanical property, and meanwhile enough moving space is reserved for the hydraulic cylinders driving the manipulator fingers; and the disc-shaped hobbing cutter disassembling and assembling block has stretching and retracting functions, is provided with a rotating mechanism, can automatically adjust and align when positioning precision is not high and is suitable for a wider manipulator precision interval.

Description

[0001] Technical field: [0002] The invention relates to the technical field of engineering machinery, in particular to a disc-shaped hob tool changing manipulator of a shield machine and a method for using the same. [0003] Background technique: [0004] This design is for use with the disc-shaped hob tool change robot of NHI's 6.66m-diameter mud-water balance shield machine, and is used to disassemble the tool box mechanism of a specific disc-shaped hob. At present, the shield method is widely used in the construction of urban subway tunnels and cross-river tunnels, and large-diameter, long-distance shield machines have begun to be used on a large scale. The working conditions of large-diameter shield machines are usually uneven composite formations, and the hobs in some areas of the entire cutterhead need to be replaced frequently. The tool change method of the shield machine is divided into pressure tool change and normal pressure tool change. Although the normal pressur...
