KAM-500型和KA-2M-300型钻机在提升或降下钻具时,钢绳容易卷乱,操作者为使钢绳有次序的绕卷和藉此支持正在操作的身体,常常用手持钢绳,为此,曾发生不少人身事故.最近我队仿制了一种钢丝绳安全套筒,使操作者既方便又安全.将一根内径比钢绳直径大5～8公厘的铁管,切成170公里长,两头锤成喇叭口,并在朝上一头的喇叭口端钻两个小孔,将钢绳套入管内,安全套上的小孔以两根电线或铅丝穿上,掛在第一层台板下,操作时手可以拿住安全套进行操作.
The KAM-500 and KA-2M-300 rigs tend to be messy when lifting or lowering the drill rig. Operators often use hand-held steels to wind coils in order and thereby support the body under operation Rope, for which, a lot of personal accidents have occurred. Recently, I team imitation of a wire rope safety sleeve, so that the operator is convenient and safe. Will be an inner diameter of 5 to 8 mm larger diameter steel pipe, cut Into 170 kilometers long, two hammer into a bell mouth, and in the upward end of the bell mouth drill two holes, set the steel cord into the tube, the condom hole with two wires or lead wire to wear, hanging in the A layer of platen, the hands can hold the condom for operation.
