卷筒是卷扬机的关键部件。有关部门曾对国内使用十年以上的缠绕式提升机作过调查,发现80％的卷筒有裂缝、凹陷、焊缝开裂、联接螺钉剪断等现象。对4米卷筒有限元电算结果表明,其安全系数仅1.94。缠绕式卷筒强度普遍薄弱的状况,严重地影响到矿山提升设备的寿命。在各种载荷、材质的筛选计算中发现,改变筒壳的弹性模量,将引起筒壳应力的巨大变动。为此,笔者以铝卷筒为例,对φ1.6米单绳缠绕式卷扬机的柔性卷筒(为了论述方便,把小于钢绳弹性模量的材料称为柔性,反之则为钢性)进行了探索。 The reel is a key part of the winch. The relevant departments have conducted surveys on domestic use of winding hoists for more than ten years and found that 80% of the reels had cracks, dents, cracks in the welds, and shearing of the connecting screws. Finite element analysis of the 4m reel shows that its safety factor is only 1.94. Wound drum strength is generally weak, seriously affecting the life of mine lifting equipment. In a variety of load, material screening calculations found that changing the shell elastic modulus, will cause a huge shell stress changes. To this end, the author of aluminum reel, for example, the φ1.6 m single rope winding winch flexible reel (for ease of discussion, less than the elastic modulus of the material is called flexible, otherwise steel) Exploring.
