Description

一种巷道冒顶隐患自动检测装置 技术领域
本发明属于煤矿安全检测技术领域，具体涉及一种巷道冒顶隐患自动检测装置。
背景技术
巷道冒顶严重威胁煤矿的安全生产，准确了解巷道顶板围岩结构、岩性及其破坏程度，并评价巷道所存在的冒顶风险，对科学合理的巷道支护设计至关重要。目前，矿井巷道冒顶隐患探测的方法主要有钻孔窥视和顶板岩性探测。钻孔窥视能够直观地了解到巷道围岩结构、岩层岩性及裂隙分布情况，但需专门钻孔和专人管理，由于钻孔的设置存在差异性，矿工的手工作业有人为因素的影响，从而不能准确判断煤巷顶板的支护效果。对于高密度的探测，其工作量较大；现有的矿用顶板岩性探测仪虽能够在锚索钻孔施工过程中探测巷道顶板岩性，但仪器还存在着结构设计不合理、测量精度低、数据传输不畅等问题。
在巷道掘进头施工开挖前，还要通过一些措施排查冒顶隐患，矿工采用一个长杆对顶板和两侧的岩体进行敲击，从而排除冒顶隐患，习惯称为敲帮问顶，这也是由于对顶板隐患监测不准确的一种补救措施，而且也存在风险。
基于以上问题，需要研发一种新的巷道冒顶隐患自动检测装置，对于巷道顶部存在冒顶隐患的进行自动检测、分级以及标识。整个装置不需要巷道内施工作业，不需要专人管理，更不需要矿井工作人员进入有冒顶隐患的巷道内进行检测。实现检测细致化、巷道内无人化、信息数据化、操作远程化。有效减少因人工敲帮问顶造成的矿井工作人员出现伤亡的情况，确保矿井安全高效生产。使测试能够随时随地进行，尽可能普及到所有位置，提供可靠 的顶板离层数据，对巷道施工质量的检查和管理确保施工安全意义重大，但至今未见有公开报导。
发明内容
本发明为了解决现有技术中的不足之处，提供一种巷道冒顶隐患自动检测装置。
为解决上述技术问题，本发明采用如下技术方案：一种巷道冒顶隐患自动检测装置，包括机器人主体，机器人主体的胸腹部内部设有电源、控制系统、存储系统、自动分级系统和信号接收器，机器人主体的两个足部为履带式行走系统，机器人主体头部的双眼处均设有高清摄像头，机器人主体头部的双耳处均设有超声波发生器，机器人主体的两个上臂内分别设有一套喷射标识系统，两套喷射标识系统喷出的涂料颜色不同，电源通过控制系统为存储系统、自动分级系统、信号接收器、履带式行走系统、高清摄像头、超声波发生器和喷射标识系统供电；控制系统分别通过控制电缆与存储系统、自动分级系统、信号接收器、履带式行走系统、高清摄像头、超声波发生器和喷射标识系统连接；信号接收器、高清摄像头、超声波发生器和喷射标识系统的工作方向均斜向上设置。
机器人主体的两条腿部设有弹簧式减振平衡系统。
自动分级系统内置根据煤矿安全规定以及矿井生产需要分为不同的冒顶趋势级别。
在履带式行走系统沿巷道底板的中心线行进时，两个超声波发生器根据巷道断面大小任意改变扫描面积以覆盖整个巷道顶板，履带式行走系统的前侧设有行进方向控制装置。
喷射标识系统为任意角度旋转的水枪式喷射涂料装置，喷射标识系统内装有不同种类的涂料颜色，可根据自动分级系统的设置不同，喷射出不同颜色序列。
存储系统用于存储三位立体图形和巷道坐标数据。
整个自动检测装置为矿用安全性防爆装置。
高清摄像头对巷道顶板进行拍照和录像，并通过控制系统将画面传输到地面监控室，监控室显示巷道顶板实时画面，记录巷道内环境状况。
采用上述技术方案，本发明的自动检测工作过程为:首先确定需要检测巷道地点，只需要将本发明放到整个检测巷道的起点，打开整个装置的电源开关，该装置自动进行巷道冒顶隐患检测作用，整个检测过程无人化、操作远程化、5G画面传输实时化；在本发明沿巷道行进过程中，超声波发生器向巷道顶板发出超声波，再由信号接收器接收超声波反射波，传送到自动分级系统，自动分级系统根据超声波特征及参数，将巷道顶部岩石具有冒落隐患的部位进行分级处理，之后将信息传输到控制系统，控制系统将信息储存到存储系统当中，同时控制系统对喷射标识系统发出启动的信号。喷射标识系统可根据不同冒落等级喷射出不同颜色的涂料。存储系统便于存储巷道顶板整体冒落隐患情况的数据以及数据提取。方向控制装置主要控制整个装置的移动方向，避免撞壁。电源为所有系统、装置连接，提供动力保障。
本发明测定巷道顶板的超声波反射波特征及参数，用计算机进行计算，确定危险参数阈值；本发明还可用于在巷道掘进过程中，对施工的巷道顶板进行监测，超声波发生器发射超声波，超声波在岩体内传播，遇到巷道顶板内岩块裂缝或者岩层离层会发生反射，信号接收装置接收超声波返回的特征 及参数；根据反射波谱特征及参数，自动分级系统自动处理信号波特征，根据不同波长以及参数，确定巷道顶板岩块裂缝等级。
将巷道顶部岩石具有冒落隐患的部位进行分级处理之后，信息会自动传递到控制系统，控制系统对喷射标识系统发出信号，喷射标识系统根据等级不同，对于巷道表面岩块喷射出不同颜料作为标记岩块冒落的危险程度；对于顶板内部岩块裂缝或者离层，会实时传输巷道三位立体画面，并且标记有冒落危险的部位。情况严重时会经过信号接收器向操作中心发出报警信息，便于矿井工作人员及时采取相应的措施来处理隐患，保证煤矿生产安全。
喷射标识系统内装有不同种类的涂料颜色，对于巷道表面岩块可根据自动分级系统的设置不同，喷射出不同颜色序列。对于巷道顶板内部岩块裂缝或者离层，会实时传输巷道三位立体画面，并且标记有冒落危险的部位。情况严重时会经过信号接收器向操作中心发出报警信息，便于矿井工作人员及时采取相应的措施来处理隐患，保证煤矿生产安全。
综上所述，本发明在检测过程中，真正实现巷道检测无人化，不需要进行打孔安装仪器，也不需要花费时间等待测试结果，远程操控即可；能简化测试程序，减少测试时间，提高测试面积以及测试精度，保证测试结果的可靠性，节约了大量人力物力和财力，有良好的经济和社会效益。
