Test bed for verifying function of TBM tool changing robot

Abstract

The invention provides a test bed for verifying the function of a TBM tool changing robot, and belongs to the technical field of mechanical structure design. A reduced scale test bed needs to be ableto meet hob poses at different positions for the current mainstream structural style of a TBM tool disc and a main beam; meanwhile, available space resources in the tool disc and the front end of themain beam are considered to provide an installation interface for the later tool changing robot. Comprehensively considering the above two aspects, the reduced scale test bed is designed in two parts.The first part is a tool disc simulation part which mainly provides simulation of different hob poses; and the second part is a main beam simulation part which mainly provides space constraint of thefront end of the main beam and the interface allowing for the tool changing robot to install. Thus, the size and weight of the test bed are greatly reduced, meanwhile, different poses of hobs can besimulated at many times, and the space working ability of the robot developed in the future is tested more comprehensively. The test bed provides a method reference for laboratory level function verification of large-scale engineering equipment.

Description

technical field [0001] The invention relates to a test bench for verifying the function of a tool changing robot of a full-face rock boring machine (TBM), and belongs to the technical field of mechanical structure design. Background technique [0002] Full-face rock boring machine (TBM) is a special equipment for tunneling, which integrates the functions of cutting rock mass, supporting, and transporting rock slag. Widely used in water conservancy projects, railway transportation, subway projects, oil and gas pipelines and tunnel construction for national defense. However, the degree of automation of some of its key operating systems is still relatively low, which is prominently reflected in the fact that the tool replacement operation in the cutter head system is still mainly manual, and automation and intelligence are even more out of the question. Combined with the national intelligent manufacturing and other planning, in order to realize the continuous improvement of my...

Problems solved by technology

In case of harsh construction conditions, it takes up to 1 hour to manually replace a single hob, and the total time spent on tool replacement is about one-third of the entire construction period, and the operators often need to withstand high-load work intensity, and long-term work will be harmful Irreversible damage to the human body, and even major accidents such as casualties

At present, relevant foreign companies and research institutes have begun to concentrate on research in this area, but the research results and progress are extremely confidential
