一种滚轮移动式排绳装置
摘要：
本发明公开了一种滚轮移动式排绳装置，包括相互平行设置的第一支架和第二支架，第一支架和第二支架之间连接有第一横向导轨，第一支架和第二支架之间还连接有与第一横向导轨平行的第二横向导轨，第一横向导轨连接有滑轮装置的一端，滑轮装置的另一端连接第二横向导轨。该石油钻机用滚轮移动式排绳装置采用滚轮替代了传统的导向套，绞车滚筒排绳时排绳装置移动时的摩擦力由滑动摩擦力变为滚动摩擦力，减小了摩擦阻力，防止排绳装置沿滚筒左、右方向移动时阻力过大导致的排绳不畅。
摘要（英）：

The invention discloses a roller movable type rope guide device. The device comprises a first support and a second support which are arranged in parallel. A first transverse guide rail is connected between the first support and the second support. A second transverse guide rail parallel to the first transverse guide rail is further connected between the first support and the second support, the first transverse guide rail is connected to one end of a pulley device, and the other end of the pulley device is connected with the second transverse guide rail. The roller movable rope guide device for a petroleum drilling machine adopts a roller for replacing a traditional guiding sleeve, during winch roller rope guiding, friction force generated when the rope guide device moves is converted intorolling friction force from sliding friction force, friction resistance is lowered, and the phenomenon that rope guiding is not smooth due to the fact that resistance is excessively large when the rope guide device moves in the left-right direction of the roller is avoided.
