用于井下导线点的激光悬挂测钉
本技术涉及用于井下导线点的激光悬挂测钉。
技术介绍
现有技术中需要对矿山进行测量标定,标定时需要使用测钉。由于井下作业环境复杂,巷道往往存在气流,使得悬线摆动,影响观测效果,另井下光线昏暗,需测量人员用手电对垂线在合适部位进行照射后,仪器操作人员方可观测,若距离较远时,仪器操作人员与照线人员交流沟通困难,难以指挥照线人员调整手电光线照射角度,影响测量速度。仪器对导线点进行距离测量时,后视人员需将反射片固定于垂线上,由于垂线悬空不便稳定,测量距离时容易使得反射片并不位于导线点的铅锤面上,从而影响测量精度。现有技术中CN208564630U公开了一种用于煤矿井下的反光装置,包括测钉、橡胶帽和垫圈,橡胶帽表面上附着有一层反光材料层。虽然这种方式使得测量人员的照射容易找到测钉,但是仍需要一定时间,找到测钉后,仍需要悬挂反射片或其他装置。
