This invention belongs to the technical field of auxiliary equipment for slurry balance pipe jacking machines, specifically a balancing device for slurry balance pipe jacking machines. The device includes a tunneling machine, an internal cutterhead assembly, a slurry conveyor on the right side of the cutterhead assembly, a pipe on the right side of the tunneling machine, and a bolster on the right side of the pipe. Multiple hydraulic cylinders are mounted on the upper end of the bolster, and a leveling device and a fixing device are installed on the top of the bolster. Through the above structural cooperation, when the bolster tilts, the inclined end of the sleeve shaft drives a bevel gear to move along the driven rod, causing the inclined bevel gear to mesh with a second bevel gear. Power is provided by a motor, causing the threaded rod to connect with the sleeve rod, thereby moving the base up and down to achieve horizontal adjustment of the bolster. This prevents the tunneling machine from shifting due to the bolster's tilt, reduces the eccentric force on the device, and improves its service life.

This invention relates to the field of tunnel boring machine (TBM) design technology and discloses a tool layout method for a circular cutterhead of a TBM. The method includes: constructing a mathematical model of tool layout incorporating cutting force data from a CSM model; determining the optimization objective and constraints for minimizing eccentric force and eccentric moment; initializing a gray wolf population by mapping discrete permutations to continuous vectors using a continuous encoding strategy and calculating fitness values; executing a global iteration of the gray wolf optimization algorithm, using social hierarchy to guide population updates; embedding a tabu search strategy in the global iteration to perform local neighborhood search on the optimal individual to generate and selectively replace the optimal solution; and finally outputting the tool layout scheme and verifying its feasibility. This invention effectively solves the problem of tool layout easily getting trapped in local optima through the synergistic cooperation of the gray wolf algorithm and tabu search, improving the mechanical balance and solution efficiency of the cutterhead design, and reducing design and production costs.
