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

Abstract

The invention relates to a simulation test bench for the cutter head of a shield tunneling machine and a use method of the simulation test bench. The simulation test bench comprises a cutter head, a worm wheel / worm structure, a base, a storage cutter bin and a mechanical arm mounting bin; the cutter head is rotatably mounted on the base through a mounting plate; the storage cutter bin and the mechanical arm mounting bin are both mounted on the base; the worm wheel / worm structure is mounted on one edge of the base and is located at one side of the 1 / 4 of the surface of the cutter head; a worm wheel shaft in the worm wheel / worm structure is coaxially and fixedly connected with the shaft of the mounting plate; the worm wheel / worm structure is provided with a hand wheel; and the hand wheel isfixedly and axially connected with a worm shaft in the worm wheel / worm structure. The test method includes the following steps that: a hobbing cutter box is fixed; a cutter head is rotated; the cutterhead is fixed; a cutter change robot is installed; and cutter change is simulated, position information is inputted to the cutter change robot, and the trajectory planning and motion accuracy of thecutter change robot are verified. According to the simulation test bench of the invention, the worm wheel / worm integrated structure is adopted, so that separate small parts are avoided, and therefore,the simulation test bench has the advantages of convenience in installation and operation, structural simplicity and easiness in processing, and meets a strength requirement and conforms to actual engineering application.

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...

Problems solved by technology

[0006] Aiming at the shortcomings in the prior art that there is no simulation test bench that can cooperate with the hob tool change robot to simulate tool change, the problem to be solved by the present invention is to provide a simulation test bench for the shield machine cutter head and its use method, using A tool change that simulates actual working conditions with an auxiliary disc hob tool change robot
