Shield tunneling machine assembly machine angle wireless measurement system and measurement method and application

Abstract

The invention provides a shield tunneling machine assembly machine angle wireless measurement technical scheme, and belongs to a technology of shield tunneling machine assembly machine angle wireless measurement. A position signal of an assembly machine is fed back to a control center PLC by using a transmission device of a Bluetooth signal, and the control center PLC limits or controls various actions of the assembly machine to act within a safe range according to the current position signal. A single-axis inclinometer is connected with a first Bluetooth module group through a measurement cable and rotates along with the assembly machine, thereby saving a special cable for rotation and tensile resistance, and solving the trouble of rotation wiring of the assembly machine. The scheme provided by the invention does not need to arrange a control cable or a communication cable passing through a winding drum or a tank chain, thereby simplifying the mechanical structure design, saving the cost, and being convenient to install. The assembly machine does not need to disassemble and assemble the control cable, thereby reducing the labor, and improving the efficiency. The scheme is very suitable for the concept of efficient assembly and fast tunneling of the shield tunneling machine, and has great popularization values.

Description

technical field [0001] The invention relates to the fields of optimization of assembly rotation of a shield machine assembly machine and wireless angle measurement, in particular to a wireless measurement system for the angle of a shield machine assembly machine and a wireless measurement method for the angle. Background technique [0002] Shield machines generally adopt the method of assembling segments when excavating tunnels, and form newly excavated tunnels into tunnels with supporting linings. These tunnels can be used for subways, railways, highways, water diversion, underground pipe galleries, etc. [0003] At present, most of the shield machines such as China Railway Construction, China Railway Equipment, Herrenknecht, Komatsu, Ishikawa Island, and Huasuitong use tank chains or cable reels to arrange control and signal cables, which generally have the following shortcomings: ( 1) Various mechanical damages are prone to occur, including cable damage due to mechanical ...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the shield machines such as China Railway Construction, China Railway Equipment, Herrenknecht, Komatsu, Ishikawa Island, and Huasuitong use tank chains or cable reels to arrange control and signal cables, which generally have the following shortcomings: ( 1) Various mechanical damages are prone to occur, including cable damage due to mechanical vibration, collision, impact and wear, and damage to the inclinometer; Large vibrations cause damage to cable reels and tank chains; (3) Many shield machines of Japanese brands do not have angle measuring devices, only the switch limit of the mechanical structure, and it is very difficult to know the angle of the assembly machine or adjust the limit; (4) The protection of the angle measuring device is not enough, the waterproof level is not enough, and the service life is reduced in the harsh environment; (5) The measurement method of the absolute value encoder is adopted, which has high requirements on the mechanical structure and is very expensive

[0004] The angle is measured in a wired way. When the assembly machine rotates, the arm, front and rear and small claws of the assembly machine communicate in a wired manner, that is, the guide cable is fixed on the tank chain device, and runs back and forth in the tank chain with the rotation of the assembly machine. The control cables and communication cables are introduced into the junction box, and the tank chain is moved on its guide rail by rotation to drive the transmission of data. There is a risk that the cables will be broken when the assembly machine rotates.
