石油钻机的电驱动系统装置是整个钻机的核心部分。装载电控设备的动力房因其体积大、质量重，搬运过程中如何保证起吊对房体不变形破坏是房内电控设备维持安全正常运行的关键。现介绍用一台起重机起吊动力房时钢丝绳对房体可能造成的破坏，推导出钢丝绳作用于房体顶盖上的力的关系和力作用点（吊点）之间的距离关系式 The electric drive system of the oil rig is the heart of the rig. Powerhouse loading electronic control equipment because of its large size, heavy weight, handling how to ensure that the lifting of the deformation of the body is not deformed room is the key to maintaining the normal operation of electronic control equipment. Now introduce the possible damage caused by the wire rope to the house when lifting the power house with a crane, and deduce the relationship between the force acting on the roof of the house by the wire rope and the distance between the points of action (hanging point)
