Abstract

The invention discloses a TBM propelling supporting hydraulic system designed in an energy-saving manner. The TBM propelling supporting hydraulic system comprises an oil source system, a propelling system, a supporting system and an oil tank; the propelling system and the supporting system are connected with the oil tank through the oil source system; the propelling system is in parallel connection with the supporting system, and the oil source system, the propelling system, the supporting system and the oil tank are connected through a main oil path and a guide oil path; the guide oil path is provided with a load sensitive valve, a variable cylinder, a pressure switching valve and an energy accumulator to carry out supporting and propelling control; and a pump is arranged to supply oil to a supporting oil cylinder large cavity under the pressure cutting-off station, after supporting is completed, the energy accumulator carries out pressurizing, the pump is arranged to supply oil to the propelling oil cylinder under the load sensitive station, and energy-saving optimization of the propelling supporting system is achieved.

Description

technical field [0001] The invention relates to a TBM hydraulic system, in particular to an energy-saving designed TBM propulsion support hydraulic system. Background technique [0002] Tunnel Boring Machine (TBM) for short is a large-scale tunnel excavation lining complete set of equipment integrating multi-disciplinary technologies such as machinery, electricity, hydraulic pressure, measurement, and control. TBM integrates excavation, ballast removal, primary support, ventilation and dust removal, tunnel track laying, and wind, water and electricity extension in tunnel construction. It has the advantages of fast, high quality, and safety. It is currently the most advanced long tunnel construction method in the world. . [0003] The TBM relies on the support system to push the brace shoes against the cave wall to achieve support. The motor drives the cutter head to cut the rock and soil, and is pushed forward under the action of the propulsion system. Therefore, the propul...
