A simulation test bench for shield machine cutter head and its use method

Abstract

The invention relates to a simulation test bench for a shield machine cutterhead and a method of using it, which includes: a cutterhead, a worm gear structure, a base, a tool storage bin and a manipulator installation bin, wherein the cutterhead is rotated and installed on the base through a mounting plate. , the tool storage bin and the manipulator installation bin are both installed on the base. The worm gear structure is installed on the edge of the base and one side of the 1 / 4 cutterhead surface. In the worm gear structure, the worm gear shaft and the axis of the mounting plate are coaxially fixed together. , a handwheel is provided on the worm gear structure, and the handwheel is fixedly connected to the worm in the worm gear structure in the axial direction; the method is: fixing the hob cutter box; rotating the cutterhead; fixing the cutterhead; installing the tool changing robot; simulation To change the tool, input the position information to the tool changing robot to verify its trajectory planning and movement accuracy. The simulation test bench of the present invention adopts an integrated worm gear structure to avoid the appearance of separate small parts, facilitates installation and operation, has a simple structure, is easy to process, meets strength requirements, and is consistent with actual engineering applications.

Description

technical field [0001] The invention relates to a construction machinery test device, in particular to a simulation test bench for a shield machine cutterhead and a method for using the same. Background technique [0002] At present, there are two ways to change the tool of the slurry balance shield machine, normal pressure tool change and pressure tool change. , the conditions for manual tool change under pressure are harsh. Operators enter the mud tank under pressure to inspect and replace worn hobs. They need to withstand high pressure and high humidity, and are prone to accidents and life-threatening. In the case of immature technology of tool changing robots, it is not convenient to carry out tool changing experiments in actual working environments. [0003] The disc-shaped hob of the slurry balance shield machine needs to be replaced many times during the entire project period, and each time the hob is replaced, the angular position of the hob that needs to be replac...
