Automatic identification system, identification method and shield machine for the swing position of shield machine cutter head

Abstract

The invention discloses an automatic identification system and identification method for the swing position of the cutter head of a shield machine, and the shield machine. The identification system is used to identify the swing position of the cutter head according to the state of the cutter head swing oil cylinder, which includes an analog module, a PLC control The cutterhead swing cylinder contains at least three partitions, each partition is equipped with a partition cylinder and a cylinder stroke sensor, and the partition cylinder can make the cutterhead Swing occurs, each oil cylinder stroke sensor is used to monitor the current stroke value of its corresponding partition oil cylinder and feed back the current stroke value to the PLC controller through the analog module in real time; the PLC controller can The current stroke value of the oil cylinder is used to obtain the current swing position of the cutter head. The automatic recognition system for the swinging position of the shield machine cutter head provided by the present invention can accurately locate the current spatial position of the shield machine cutter head in real time, and provides shield tunneling machine operation technology decision-making for the shield machine driver.

Description

technical field [0001] The invention relates to the field of shield machine control, in particular to an automatic identification system and identification method for the swing position of a cutterhead of a shield machine and the shield machine. Background technique [0002] As the National Development and Reform Commission issued the "Layout Plan for the Main Line of the Yangtze River Crossing Channel (2020-2035)", according to the plan: by 2025, about 180 channels for crossing the river will be built; by 2035, the planning and layout of the main line of the Yangtze River crossing channel 276 seats. Efforts should be made to promote the construction of multi-functional passages to realize the combination of railways, highways, urban traffic and other means of crossing the river. The construction of intelligent super-large-diameter shield tunnels is the first choice. With the gradual increase in construction projects, the construction difficulty is also increasing.

Problems solved by technology

Efforts should be made to promote the construction of multi-functional passages to realize the combination of railways, highways, urban traffic and other means of crossing the river. The construction of intelligent super-large-diameter shield tunnels is the first choice. With the gradual increase in construction projects, the construction difficulty is also increasing. It is difficult to automatically perceive the position of the disc space underground, and it is impossible for the shield operator to grasp the position information of the cutter disc in real time during the shield operation process, and make accurate operation decisions based on the position information, which increases the difficulty of construction and reduces the construction efficiency
