Problems solved by technology

At present, in the top drive drilling equipment at home and abroad, the installation of the guide rail is mainly connected by the pin shaft. Due to the mechanical structure of this method, the guide rail is suspended by the rope at an altitude of more than 30 meters, and the pin shaft holes on the two guide rails are extremely difficult to align. , It is difficult to connect with pin shafts, it often takes more time to install, and the workload of the staff is relatively large

Abstract

The invention provides a fast installing device for a top drive guide rail. The guide rail comprises an outer guide rail body and an inner guide rail body; the outer guide rail body is a hollow body and provided with a ratchet wheel limiting and guiding device; the inner guide rail body is provided with an ejecting block device making the ratchet wheel limiting and guiding device move; when the inner guide rail body is inserted in the outer guide rail body, the ejecting block device and the ratchet wheel limiting and guiding device are in contact so that connection pin holes of the outer guide rail body and the inner guide rail body can be centered; and a third pin shaft is inserted in the pin holes and locked so that installation of the top drive guide rail can be completed. The fast installing device for the top drive guide rail solves the problems that an adjusting plate, connected with a crown block, on an existing guide rail and a first segment of the guide rail are low installing efficiency, the aerial work time is long, and the labor intensity is high.

Description

technical field [0001] The invention relates to the technical field of top drive drilling equipment, in particular to a quick installation device for top drive guide rails in the top drive drilling equipment. Background technique [0002] As an indispensable part of the top drive equipment, the guide rail not only enables the top drive to slide up and down along the guide rail, but also can withstand the reaction torque of the drill pipe driven by the top drive during rotary drilling, make-up and breakout. At present, in the top drive drilling equipment at home and abroad, the installation of the guide rail is mainly connected by the pin shaft. Due to the mechanical structure of this method, the guide rail is suspended by the rope at an altitude of more than 30 meters, and the pin shaft holes on the two guide rails are extremely difficult to align. , It is difficult to connect with pin shafts, and it often takes more installation time, and the workload of the staff is relati...
