| 摘 要： | 地表钻参仪在深孔岩心钻探中可以实时检测和监控钻进参数，优越性明显，其中大钩位置是钻参仪检测的难点。研究了一套大钩位置检测装置，在天车上安装双通道霍尔开关，接收定滑轮上磁钢的脉冲信号，经过数显表头的微处理系统转换，再通过RS232串口通信连接PC机，基于LabVIEW平台实现数据的采集、分析、显示和存储等工作。该检测装置可以直接测量机上余尺或者方钻杆余尺，计算大钩位置防止撞顶天车，计算二层台位置便于挂卸提引器。深钻现场试验表明，该装置安装简便，测试精度高，可用于检测立轴式钻机和转盘式钻机大钩位置。

The design and application of hook position detector for deep drilling |
| |
| Abstract: | With the increasing contradiction between resource supply and demand, searching deep resources will become our key work in resources exploration. The advantage of surface drilling monitor is distinct as it is able to detect and monitor the drilling parameters in real time during deep drilling, while the testing of hook position remains difficult. This paper designs a hook position detector, which installs double channel hall sensors on the crown block to detect the pulse signals, after the transformation of micro programming system within the digital display header, the hander connects PC by serial port and can carry out the acquisition, analysis, presentation and storage of the data based on the LabVIEW platform. We can reap the following benefit by using this detector, test the remaining distance of drilling rig directly, judge the position of the hook in case it crashes into the crown block and calculate the racking platform position for easier putting on and putting off the hoisting swivel elevator. Our deep drilling test in filed has proved that this equipment is easy to install and accurate. It is handy to be applied to detect the hook position of vertical drilling rig and rotary drilling rig. |
