A knife box mechanism of a disc-shaped hob of a shield machine and its use method

Abstract

The invention discloses a disc hobbing cutter box mechanism of a shield tunneling machine and an application method thereof. The disc hobbing cutter box mechanism comprises a box body and a rotation mechanism, wherein a hobbing cutter installing mechanism is arranged in the box body, one side of the hobbing cutter installing mechanism is fixedly connected with a hobbing cutter, and the rotation mechanism is installed on the other side of the hobbing cutter installing mechanism; the rotation mechanism comprises a rotation mechanism installing block and a rotation box installed on the rotation mechanism installing block. A cutter box is simple in structure and easy to machine, and meets strength requirements. The cutter box is structurally integrated and free of any independent small part, and operation by a robot is convenient. When the disc hobbing cutter box mechanism is used in cooperation with a manipulator, torque generated in the rotation process of the rotation mechanism on the cutter box can be transmitted to the box body through mechanical fingers, and a mechanical arm does not need to bear the torque. A bevel arranged on a left baffle and a bevel arranged on a right baffle of the rotation mechanism installing block can prevent the left baffle and the right baffle from getting stuck in the box body. The rotation mechanism is installed behind the hobbing cutter installing mechanism, and the hobbing cutter is prevented from being scratched by falling rock-soil in the rock-soil cutting process.

Description

Technical field: [0001] The invention relates to the technical field of engineering machinery, in particular to a cutter box mechanism of a disk-shaped hob of a shield machine and a use method thereof. Background technique: [0002] This design is aimed at the cutter box mechanism of the detachable disc hob used by the disc hob tool change robot of the mud-water balance shield machine with a diameter of 6.66m in NHI. At present, there are two ways to change the tool of mud-water balance shield machine, normal pressure tool change and pressure tool change. The mud-water balance shield machine of NHI usually adopts manual tool change under pressure. The inside of the slurry tank (excavation cabin) of the mud-water balance shield machine is filled with high-pressure gas during the working process, and the conditions for manual tool change under pressure are harsh. Operators enter the mud tank under pressure to inspect and replace worn hobs. Not only do they need to withstand h...
