Abstract

The invention discloses an automatic and random grouping push control system of a shield tunneling machine. The automatic and random grouping push control system comprises a push oil cylinder reverse control device set and a plurality of push oil cylinder thrust control device sets, the signal control ends of the push oil cylinder thrust control device sets and the signal control end of the push oil cylinder reverse control device set are connected with an upper computer of the shield tunneling machine, and the upper computer sends signals to the push oil cylinder thrust control device sets and the push oil cylinder reverse control device set to adjust the push posture of the shield tunneling machine in real time by adjusting the maximum thrust of an oil cylinder. The shield tunneling machine can advance precisely along designed tracks, construction quality can be improved, and construction efficiency can be improved.

Description

technical field [0001] The invention relates to the field of shield machines, in particular to an automatic arbitrary grouping propulsion control system for shield machines. Background technique [0002] At present, during the propulsion process of the shield machine, there will be a problem that the propulsion track deviates from the construction design track, and more seriously, there may even be a problem of redesigning the location of the subway station entrance. Due to the huge equipment of the shield machine, the propulsion system currently designed in the shield industry needs a long time to correct the deflection of the shield posture after the deviation, so that returning to the design trajectory requires a distance of tens of meters or even hundreds of meters. This has just had a strong impact on the quality of construction, lengthened the construction period, and reduced construction efficiency. Contents of the invention [0003] The purpose of the present inve...
