In order to solve the technical problems existing
during assembly of the traditional arc parts (boxshaped
piece) for shield tunnels, such as unadvanced assembly technology, poor
assembly accuracy, low degree of equipment intelligentization, slow
construction progress, etc., an intelligent walkthrough
assembling machine for arc parts is developed, by introducing the concept of
equipment design and intelligent control, adopting the design idea of walkthrough arcshaped components, and combining
the millimeterlevel loadsensitive
hydraulic system and submillimeter level attitude
monitoring system. It can realize intelligent assembly of arc parts with onebutton operation. The assembling machine is equipped with
intelligent control technology such as fineadjustment
measurement system, automatic detection and perception, automatic calculation
and analytical processing, automatic decision making and action execution,
humancomputer interaction and information storage,
etc. It has been applied for the first time in Contract JCXSG11 of Shanghai rail transit airport link line, and has achieved good
performance in assembly. The results show that: (1) The control accuracy of the
hydraulic system of assembling machine is up to 0.5 mm, and the assembly
accuracy of arc parts is up to ±5mm, and thus highprecision assembly is achieved. (2) Through the intelligent control
technology, onebutton operation is realized for the
assembling machine. It takes 32 min for each cycle, improving the construction
efficiency by more than 30%, and saving labor by more than 50%. (3) The
intelligent walkthrough assembling machine for arc
parts has stable and reliable performance, which can record and store the
parameters such as operation state, control mode, sensor data, hydraulic
cylinder stroke data and communication state, and realize humancomputer interaction.
