Abstract

The invention discloses a shield machine swinging oil cylinder action stroke control system and control method, and a shield machine. The control system is used for controlling a cutter head swingingoil cylinder, and the system comprises an analog quantity module, a PLC controller and an upper computer; the cutter head swinging oil cylinder at least comprises three partitions, each partition is provided with a partition oil cylinder and an oil cylinder stroke sensor, and each oil cylinder stroke sensor is used for monitoring a current stroke value of the corresponding partition oil cylinder and feeding back the current stroke value to the PLC controller through the analog quantity module in real time; and the PLC controller can obtain a target swing angle of a cutter head and a target stroke value of each partition oil cylinder according to an input instruction of the upper computer, and controls the expansion and contraction of each partition oil cylinder according to the stroke value of each partition. The control system can meet the space required by shields with different diameters for changing cutters of the cutter head, provides great convenience for changing the cutters, and is also beneficial to restoring the rotation of the cutter head.

Description

technical field [0001] The invention relates to the field of shield machine control, in particular to a shield machine swing oil cylinder movement stroke control system, control method and shield machine. Background technique [0002] With the construction of the urban subway in full swing, the shield machine has also achieved considerable development, and new technologies and equipment are emerging in an endless stream. As a new technology, cutterhead swing is mainly used to provide ample space for cutterhead tool replacement, which is particularly important in some large-diameter shield machines. Because changing the tool is a time-consuming and labor-intensive job, sometimes it is even impossible to change the tool due to insufficient space outside the cutter head, thus delaying the construction progress. Not only that, but the cutterhead swing can also solve the problem of cutterhead jamming to a certain extent. However, how to precisely control the oscillating amount ...
