- TBM full-face rock tunneling machine
- the TBM mainframe system mainly includes key parts such as cutterhead, support shield, drive motor, main beam and support boots.

一种全断面岩石掘进机关键部位振动与应变监测方法、一种监测装置及其全天候监测预警***,利用振动及应变传感器及其无线数据传输***获取监测数据,实现对全断面岩石掘进机主机***工作时关键部位振动及应变状态长期实时监测,及时提醒操作人员维护检修,防止全断面岩石掘进机主机***关键薄弱位置发生疲劳破坏,确保全断面岩石掘进机安全可靠地进行工作,同时还采用等效映射法对无法测量部位应变状态进行评估。
Description
本发明涉及一种全断面岩石掘进机主机***振动、应变实时监测与应变等效映射测量法,属于全断面岩石掘进机地下施工实时监测技术领域。
随着我国经济的发展,近年来全断面岩石掘进机(TBM)广泛用于我国的水利工程,铁路交通,地铁工程,油气管道及国防等隧道建设中。全断面岩石掘进机在作业时,由于工况复杂、服役环境恶劣等原因,具有重载、冲击的特点,最终造成TBM主机***关键薄弱部位发生磨损甚至断裂。
TBM主机***主要包含刀盘、支撑盾体、驱动电机、主梁、支撑靴等关键部位,恶劣的载荷条件是造成TBM主机***故障的重要因素,为了对主机进行抗振设计以及关键结构件的寿命估计,必须掌握TBM主机的振动情况和关键结构部位的应变情况。建立一套实时监测***对TBM主机***关键薄弱部位振动及应变情况进行监测,既可以提醒工程施工人员进行及时的检修,避免进一步的破坏,同时可以为减振方案的改进以及关键结构件的寿命估计提供依据。
由于TBM的工况十分恶劣,对TBM状态的监测极其困难。目前国内外对TBM主机***振动及应变的监测尚没有一套完整的方案。并且一些关键部位的理论危险点,由于实际工况的限制,无法安装传感器进行直接测量。虽也有一些学者或企业对掘进过程中的某一小段振动数据进行采集,由于采集的样本较少,因此具有一定的局限性。
基于以上情况,本发明对已有的振动及应变传感器,进行了总体安全性布局和局部强化保护措施,并给出一种对无法测量部位应变状态进行评估的方法——等效映射法。从而构建了一套用于TBM主机***关键部位掘进全程的振动监测、应变监测***。
本发明的目的在于提供一种监测装置及其全天候远程监测与预测***。
本发明的技术方案:
全断面岩石掘进机关键部位振动与应变监测方法,步骤如下:
全断面岩石掘进机关键部位振动和应变监测***与等效映射法,包含用于测量振动的加速度节点、测量应变的应变计及应变节点、放大采集信号的天线、接受无线信号的无线网关、显示测量数据的计算机及等效映射法测量模型。其特征在于,通过布置在TBM主机***
关键部位的无线传感器监测其运行过程中的振动及应变状态,同时基于无线网络协议接受传输振动及应变数据,实现TBM主机***关键薄弱位置运行状态的实时监测。并将测量信号输入模等效映射法测量模型,对无法测量部位的应变状态进行评估。具体的***搭建分为以下两个方面:传感器的布置;等效映射法测量模型。
Ⅰ、传感器的布置
第一步,总体安全性布局
本监测方法主要针对全断面岩石掘进机(TBM)的刀盘1、支撑盾体2、驱动电机、主梁3、支撑靴4进行测量,其总体结构如图1。为了使传感器能安全稳定地工作,首先要在各个被检测部件上选择既能反应运动状态又相对安全的测量点。参考大量实际工程,测量点选择岩渣等不易掉落到地方,具体布局如下:
选择刀盘1的振动测量点和应变测量点,在两个人孔(图2中a1所示)和两个水孔(图2中a2所示)中布置传感器,人孔中只布置振动传感器,水孔中布置振动传感器和应变传感器,振动传感器和应变传感器具***置见a1和a2位置的局部放大图,分别为图3和图4;
选择支撑盾体2(图5中b1)的振动测量点,在支撑盾体2顶部、内表面布置振动传感器,具***置如图5;
选择驱动电机(图6中c1)的振动测量点,在电机盒的侧面布置振动传感器,具***置如图6;
选择主梁3(图6中c2)的振动测量点,在主梁前端上表面布置振动传感器,具***置如图6;
选择支撑靴4(图7中d1)的振动测量点,在支撑靴4内侧面布置振动传感器,具***置如图7;
第二步,局部强化保护措施和连接
由于传感器等属于易损件,为避免岩渣冲击和地下潮湿环境导致传感器的失效,本***对传感器节点(图9中f2)和工业电池(图8中e2)等加装金属保护罩(图8中e1),以实现抗撞击和防水防潮的作用,工业电池和传感器节点的保护罩结构分别为图8中e1和图9中f1。首先,被检测部位与所有金属保护罩均采用焊接方式进行固定。其次,传感器节点(图9中f2)与保护罩采用强力磁座(图8中e3)联结,并且保护罩底部加工有与磁座相对应的凹槽(图8中e4),以确保节点在检测过程中,节点方向不会偏移。对于无线信号发射与接收天线(图4中Ⅴ)均采用磁吸附的方式固定。对于采集应变信息的应变计(图4中Ⅲ)与被检测部位采用螺纹连接固定。
第三步,供电。
***里全部的传感器用电分为两种,一种是刀盘内的传感器用电,由于刀盘为旋转部件,电源线难以布置,故采用工业电池方式供电,如图,定时更换电池即可;其他的传感器用电采用电源线直接供电的方式。
第四步,信号传输及监测。
无线网关设置在TBM主机操作室,接受TBM主机***刀盘的振动及应变信号,支撑盾体、主梁前段、驱动电机及支撑靴的振动信号,对于检测到的超出正常值得应变及振动信号就行及时预警,并显示在TBM主机操作室的计算机上,生成TBM的工作日志。
Ⅱ、等效映射法测量模型
对工件的应变等物理量的测量,由于测量现场工况以及工件本身的结构的限制,导致无法对我们关心的部位进行相关测量。下面,提出一种通过测量其他部位的应变来反求无法直接测量的关键部位应变的方法。测量模型示意图如图10,等效映射待测点S0的评估值如下:
式中:ε0为待测点S0的应变;
εi为测量点S1,S2,S3,S4的应变;
αi为各测量点的位置参数,αi=1~10;各测量点距离S0点越近,相应的αi越大;
P为测量点S1,S2,S3,S4所形成的被测部位的局部结构参数,无加强筋时,P=1,有加强筋时,P=1~10,加强筋越多,P越大;
β为突变系数,当待测点S0处有加强筋时,β=0.3~0.7;当待测点S0处有应力突变时,β=1.1~1.6,当待测点S0处无特殊结构,β=1;
误差说明:因为应变与载荷和工件结构都有密切关系,所以这种方法的应用范围不能放大,经过一些工程应用,测量圆A的直径一般不超过0.5m。由于工况的复杂性,这一评估模型并不是准确计算值,具有一定的误差,其误差在工程上可以接受。
本发明的有益效果:本发明利用振动及应变传感器及其无线数据传输***获取监测数据,实现对TBM主机***工作时关键部位振动及应变状态长期实时监测,及时提醒操作人员维护检修,防止TBM主机***关键薄弱位置发生疲劳破坏,确保TBM安全可靠地进行工作。此外,本发明提出了一种新型间接测量应变的模型——等效映射法测量模型,通过在待测点周围布置应变传感器,来计算出待测点应变,为无法直接布置传感器的部位的应变测量提供了一种方法。

下面结合附图及技术方案详细说明本发明的具体实施方式,图1为某工程的TBM主机***示意图,包含刀盘、支撑盾体、驱动电机、主梁及支撑靴等主要部件,TBM刀盘在工作过程中不停地切割岩石,刀盘受岩石冲击作用产生受载较大且载荷传递到后面的部件,造成了支撑盾体、驱动电机、主梁及支撑靴的振动。
在刀盘部位,布置在刀盘水孔内的振动传感器,采用电池供电,在适当的采样频率下电池的使用周期约为1周,采集到的振动信号经天线;布置在刀盘水孔内的应变计,对测量点进行应变得分测量,应变计配合电压节点测量应变信号,通过天线放大信号并传输至网关;除此以外,在支撑盾体、驱动电机、主梁前段以及支撑靴的振动传感器分别将各自的振动信
号经天线传至网关。
当所有传感器将信号传至无线网关后,所有数据由计算机配套软件处理,并实时显示和保存。对于等效映射测量模型,通过在S1,S2,S3,S4处布置应变传感器,以及等效映射测量点S0,从而确定评估模型的各个参数,进而计算出S0的应变。通过这样数据流动方式,TBM工作时产生的实时振动以及应变信号就可以显示在TBM主机操作室的计算机上,并生成TBM的工作日志,以实现预期的功能要求。
本发明的一种监测装置及其全天候远程监测与预测***,利用振动及应变传感器及其无线数据传输***获取监测数据,实现对TBM主机***工作时关键部件的振动及应变状态长期实时监测,并对其它无法直接测量的部位进行等效映射评估,以将TBM的工作状态及时反馈给操作人员,防止TBM主机***关键位置突发故障,确保TBM安全可靠地工作。
