凿岩台车数值输入控制定位方法

A CONTROL METHOD FOR DRILLING JUMBO LOCATION THROUGH NUMERICS INPUT

在掘进工作面上实现凿岩台车钻臂的准确定位是提高凿岩爆破效果的重要环节。以往采用手动装置，定位效率低且精度难以保证，因此最近广泛采用一种数值输入的自动控制定位方法。该法是将工作面炮孔位置的直角坐标系变换成钻臂的球面坐标系，用数值指定钻臂上凿岩机顶端的位置，用反馈控制装置将凿岩机顶端定位于设计的炮孔位置上。该法定住精度高、速度快。

The implementation of accurate boom location of drilling Jumbo at the driv-ing place is a key link to improve the drilling-blasting effects. In the past, the manually-operated locating device was used, resulting in low location efficiency and difficult ensuringfor accuracy.The recent wide use of automatically-controlled locating method, therefore,through numerics input has been made. As for this method,the right angle coordinate,sys-tem of blasthole location at the drilling face is converted into the sphere coordinate systemof drill boom, the numerics are used to designate the boom lift up the top end location ofthe drill, then the feedback control device is operated to locate the top end bit of the drillat the designed blasthole place.It is high in location accuracy and rapid in lication.
