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

Abstract

The invention discloses an automatic identification system, an identification method and a shield machine for the swing position of a shield machine cutter head. The identification system is used foridentifying the swing position of the cutter head according to the state of cutter-head swing oil cylinders, and the identification system comprises an analog quantity module, a PLC and an upper computer; each cutter-head swing oil cylinder comprises at least three partitions, each partition is provided with partition oil cylinders and oil cylinder stroke sensors, the partition oil cylinders can enable the cutter head to swing through swing spherical hinges arranged on the cutter head of the shield machine, 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 in real time through the analog quantity module; and the PLC is capable of obtaining the current swing position of the cutter head according to the current stroke value of each partition oil cylinder. According to the automatic identification system for the swing position of a shield machine cutter head, the current space position of the shield machine cutter head can be accurately positioned in real time, and a shield operation technical decision is provided for a shield 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
