Abstract

The invention relates to a top-drive guide rail assembly and a top-drive guide rail system and belongs to the technical field of petroleum machinery. The top-drive guide rail assembly comprises connecting parts, limiting parts and at least two guide rail units. Every two adjacent guide rail units are connected through the corresponding connecting part to form a connecting portion which comprises a first connecting portion body and a second connecting portion body, wherein the first connecting portion body is connected to the second connecting portion body in an inserted mode, and the first connecting portion body and the second connecting portion body are connected through the corresponding connecting part; and the second connecting portion body is provided with a thread limiting hole, and the corresponding limiting part penetrates in the thread limiting hole and abuts against the corresponding connecting part. According to the top-drive guide rail assembly, every two adjacent guide rail units are connected more firmly, and guide rail connection stability is guaranteed. The top-drive guide rail system comprises the top-drive guide rail assembly, guide rail connection for the system is stable, and normal work of top-drive guide rails can be met.

Description

technical field [0001] The invention relates to the technical field of petroleum machinery, in particular to a top drive guide rail assembly and a top drive guide rail system. Background technique [0002] In the process of oil and gas exploration and production, the oil drilling top drive equipment (referred to as top drive) is hung on the traveling car of the drilling rig. As an indispensable part of the top drive equipment, the guide rail not only enables the top drive It slides up and down, and can withstand the reaction torque of the top drive driven drill pipe during rotary drilling, make-up and breakout. [0003] At present, in the top drive drilling equipment at home and abroad, the installation and connection of the guide rail is mainly connected by the pin shaft. In the pin shaft matching of the existing guide rail, the movement of the pin shaft is mainly limited by the limit groove in the middle of the pin shaft. Because the pin shaft matching structure of the gu...
