Embodiment Construction

[0060] To clarify, when a component is said to be "set on" another component, it can be directly on the other component or there can be an intervening component as well. When a component is said to be "connected" to another component, it can be directly connected to the other component or there may be a centered component at the same time. As used herein, the terms "vertical", "horizontal", "left", "right" and similar expressions are for the purpose of illustration only and do not represent the only embodiment.

[0061] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field of the invention. The terminology used herein in the description of the present invention is only for the purpose of describing specific embodiments, and is not intended to limit the present invention. As used herein, the term "and / or" includes any and all combinations of one or more of the associ...

Abstract

The invention provides equipment for lifting a top drive drilling device. The equipment for lifting the top drive drilling device comprises a derrick, a cross beam, a first power cylinder and a secondpower cylinder, wherein the derrick is provided with a longitudinally extending guide rail; the cross beam is arranged on the guide rail and can move on the guide rail; the cross beam is used for hitching the top drive drilling device; the first power cylinder is provided with a first cylinder body and a first piston rod; the first cylinder body is connected with the cross beam; the first pistonrod can telescopically move along the longitudinal extending direction of the guide rail; the second power cylinder is provided with a second cylinder body and a second piston rod; the second cylinderbody is fixedly connected with the derrick; the second piston rod can telescopically move along the longitudinal extending direction of the guide rail; and the second piston rod is connected with thefirst piston rod. The equipment for lifting the top drive drilling device is not provided with vulnerable parts such as steel wire ropes, so that the safety coefficient of a whole drilling machine and the safety coefficient of the tripping operation are greatly improved; and traditional drilling machine components such as a winch, a crown block and a travelling crane hook are not needed, the structure is greatly simplified, and the equipment cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of drilling equipment, in particular to a device for lifting a top-driven drilling device. Background technique [0002] The statements in this section only provide background information related to the present disclosure and may not constitute prior art. [0003] The top drive drilling device is a relatively common equipment in petroleum drilling engineering. It can directly rotate the drill string from the upper part of the derrick space, and send it down along the special guide rail in the derrick to complete the rotary drilling of the drill string, circulate the drilling fluid, connect the single , make-up and breakout, back reaming and other drilling operations. [0004] In traditional oil drilling engineering, the main method is to use the winch to unwind the wire rope to lift the top-driven drilling device. This mainstream technology has played a very important role in oil drilling engineering. Neve...
