管片拼装机旋转角度检测技术研究
|
摘要
盾构施工中,管片衬砌支护使得管片拼装作业直接影响隧道质量,而管片拼装机作业速度依赖于旋转角度准确检测。针对隧道掘进机复杂工作环境造成的管片拼装机角度检测成本高、可靠性差问题,提出了一种新型拼装机旋转角度检测技术。检测过程中采用2个倾角传感器,以确定旋转机构的旋转方向(顺时针/逆时针)与旋转角度大小;通过PLC对采集角度信号进行过滤与溢出处理,同时对传感器故障造成的测量错误进行逻辑断开处理,从而实现拼装机旋转角度的稳定、可靠测量。应用结果表明,该测量方案具有安装方便、成本低、逻辑控制简单、可靠性高的特点,能够避免回转机构因转动位置不合理而导致的设备损坏或者人身伤害,可以广泛应用于不同施工条件下管片拼装机角度准确检测。
Segment lining support is necessary in shield construction;the operation of segment assembly may directly affect the quality of tunnel;while the operation of segment assembly machine depends on the accurate detection of rotation angle.Aiming at the problems of high cost and poor reliability of segment assembling machine angle detection caused by complex working environment of tunnel boring machine,a new type of rotating angle detection technology of segment assembling machine is proposed.Two inclination sensors are used to determine the rotation direction(clockwise/counter clockwise) and rotation angle in the detection process.The collected angle signals are filtered and overflowed by PLC,and the measurement errors caused by sensor faults are disconnected to achieve stable and reliable measurement of the rotating angle of the assembler.The application results show that the measurement scheme has the characteristics of convenient installation,low cost,simple logic control and high reliability.It can avoid equipment damage or personal injury caused by unreasonable rotation position of rotary mechanism and can be widely used in accurate angle detection of segment assembler under different construction conditions.
