多年来,在钻探施工中,由于对活动工作台防坠器的维护保养和检查不够,维修不及时,坠台伤亡事故时有发生。为消灭这一重大事故隐患,我队摸索出了一套防止活动台坠落的方法,杜绝了坠台事故的发生,保障了钻工的生命安全。具体做法是: (1)使用前,检查防坠器吊架与活动工作台连接处焊接是否牢靠(防止虚焊)。 (2)在地面做防坠试验。安装前将钢丝绳从上接头穿入防坠器内,把活动工作台固定,两人反向拉钢丝绳,如可拉动或滑动距离超过30mm,则认为滚柱过小,不配套或弹簧弹力不够,应予更换。
Over the years, drilling construction, due to the activities of the table anti-dropping device maintenance and inspection is not enough, maintenance is not timely, fell from time to time casualties have occurred. In order to eliminate the hidden danger of this major accident, our team worked out a set of measures to prevent the falling of the movable table, put an end to the fall of the falling table and ensured the life safety of the drilling workers. The specific approach is: (1) before use, check the anti-dropping device hanger and movable workbench connection at the welding is solid (to prevent Weld). (2) Do anti-fall test on the ground. Before installation, the steel wire rope penetrates into the anti-dropping device from the upper joint, the movable workbench is fixed, and the two people pull the steel wire rope in the reverse direction. If the pulling or sliding distance exceeds 30mm, the roller is considered too small, unsuitable or insufficient in spring force, Should be replaced.
