延长钻机绞车钢丝绳寿命的途径,除采用新结构钢丝绳和正确使用保养外,还要求保征天车、游车滑轮槽的制造质量:槽底圆应与轴孔同心,轮槽中心线应与轴孔中心线呈空间垂直。圆弧弧形正确,表面光滑。 钢丝绳在已磨损超差的轮槽里工作,受到轮槽两侧的非正常挤压而发生畸变,使用寿命显著缩短。因此,在天车,游车大修时如果发现其轮槽已磨损超差时,即应修理或更换滑轮。
In addition to the new structure of steel wire rope and the proper use of maintenance, but also asked to levy crane, the pulley pulley manufacturing quality: the bottom circle should be concentric with the shaft hole, wheel groove centerline should be with the shaft Hole centerline was vertical space. Arc arc correct, smooth surface. Rope in the wear and tear of the ultra-poor wheel groove work, both sides of the wheel by the abnormal extrusion and distortion, the service life is significantly shortened. Therefore, if the wheel and socket of the crane and the overhaul are overhauled, the pulley should be repaired or replaced.
