The invention belongs to the field of petroleum drilling machines, particularly relates to a multifunctional variable-frequency electric rope rewinding machine for a petroleum drilling machine, and aims to solve the problems that an existing brake cannot stop a rotating rope wheel timely and effectively or too quickly, and the brake is too soft or too hard. In order to solve the problem of poor rope winding caused by incapability of continuously tensioning a steel wire rope when the steel wire rope is wound on a drum of the well drilling winch due to incapability of following a well drilling winch under a large rope switching working condition, the following scheme is provided: the rope winding machine comprises a rack, a variable-frequency power system, a variable-frequency control system, a gear component assembly, a rope wheel assembly, a rope guide drum assembly and a disc brake assembly. According to the device, the purpose of winding and unwinding the drilling line can be achieved through the driving rope wheel, and the purpose of flexible braking is achieved by reasonably setting the braking time and logic of energy consumption braking and an electromagnetic brake; the variable-frequency control system ensures that the rope rewinding machine follows the drilling winch when the large rope working condition is switched, so that the steel wire rope is continuously tensioned when being wound on a drum of the drilling winch, and good rope winding of the drilling winch is ensured.
本发明属于石油钻机领域,尤其是一种石油钻机用多功能变频电动倒绳机,针对现有的刹车无法及时有效或者过于快速的停止转动的绳轮,刹车“过软”或“过硬”,倒绳机在倒换大绳工况无法随动钻井绞车使得钢丝绳往钻井绞车卷筒上缠绕时无法持续张紧导致缠绳不良的问题,现提出如下方案,包括机架、变频动力系统、变频控制系统、齿轮组件总成、绳轮总成、引绳卷筒总成、碟刹总成。本发明中,通过驱动绳轮可以实现收、放钻井大绳的目的,通过合理设置“能耗制动”、“电磁制动器”的刹车时间及逻辑,达到“柔性刹车”的目的,通过变频控制系统保证倒绳机在倒换大绳工况随动钻井绞车使得钢丝绳往钻井绞车卷筒上缠绕时持续张紧,确保钻井绞车缠绳良好。
