摘要：
The invention relates to a top drive (16) as a device for driving drill pipes and to a method for operating the same, in which means for heating the gearbox oil (46) used by the top drive (16) are provided, which means can also be supplied by an emergency power unit and comprise a hydraulic unit (28) and a pressure limitation valve (40) of the top drive (16). In order to heat the gearbox oil (46) by means of the hydraulic unit (28), hydraulic fluid (36) is circulated via the pressure limitation valve (40) and the heat energy thus generated is emitted to the gearbox oil (46) via a heat exchanger (48) through which the hydraulic fluid (36) flows.
摘要（中）：
本发明涉及一种所谓的顶部驱动器（16）作为用于驱动钻柱和操作的方法，在使用该装置，提供了用于从顶部驱动器中加热（16）齿轮油（46）的装置，它也可以与应急发电机供给和 液压单元（28）和顶部驱动装置（16），其中，用于变速器油（46）（28）的液压流体（36）加热到液压单元通过压力限制阀（40）中循环的压力限制阀（40），并通过将由此产生的热能 流经热交换器（48），以变速器油（46）中的液压流体（36）中的一个被排出。
