360°rotatable shield segment assembly device

Abstract

The invention relates to a 360° rotatable segment assembly device, including a new energy battery pack, a Bluetooth wireless transceiver, a PLC controller, a frequency converter, a hydraulic pump station motor, a hydraulic pump station, and a hydraulic solenoid valve group. The new energy battery pack, frequency converter, hydraulic pump station motor, hydraulic pump station, and hydraulic solenoid valve group are installed on the rotating body of the assembly machine; the PLC controller is installed on the shield machine body; the new energy battery pack The motor of the hydraulic pump station is connected through a frequency converter, and the PLC controller is respectively connected with the frequency converter and a relay through a Bluetooth wireless transceiver, and the relay is connected with a hydraulic solenoid valve group. The invention adopts a new energy storage battery pack + frequency converter to control the operation of the motor of the hydraulic station of the assembly machine, adopts a Bluetooth wireless transmission module with high anti-interference ability + PLC to control various actions of the assembly machine, and removes the cable tray on the original assembly machine to make the assembly machine The machine can rotate 360 ​​degrees without restriction.

Description

technical field [0001] The invention relates to a shield segment assembling device of a tunnel shield boring machine, in particular to a rotatable shield segment assembling device. Background technique [0002] With the development of shield technology, it has developed from the early subway tunnels, highway tunnels, and railway tunnels to nuclear power tunnels and hard X-ray special tunnels in high-tech applications. [0003] In all tunnel construction processes, shield tunnel boring machines are inseparable. According to the system, the current domestic mainstream shield machines are divided into two categories: Japanese shield machines and European shield machines. No matter which series, the shield segment assembly machine is an assembly machine rotating body 10, which needs to meet 360 degrees.

Problems solved by technology

According to the system, the current domestic mainstream shield machines are divided into two categories: Japanese shield machines and European shield machines. No matter which series, the shield segment assembly machine is an assembly machine rotating body 10, which needs to meet 360 degrees. Due to the limitation of the installation method of the assembly machine cable 20, the maximum rotation angle of the current shield assembly machine is between 220 degrees forward and reverse, and cannot rotate 360 ​​degrees in any direction. figure 1 As shown in (a) and (b), therefore, when assembling the shield segment, the operator of the assembling machine must alternately control the rotation of the assembling machine clockwise and anticlockwise to carry out the operation, during which some useless rotation operations will be performed, which reduces the assembly time. Efficiency, and once the rotating limit of the assembly machine is damaged and fails or the rotating cable reel is stuck on the main body, it will cause the rotating cable of the assembly machine to be broken, causing the entire construction to stop
