A fixing device for drill pipe during oil exploitation

Abstract

The invention discloses a fixing device for a drill pipe in oil exploitation. The fixing device comprises a fixedly-penetrated ring, a male installing ring, a fixedly-connected platform, a base, an external clamping ring, a precession ring, a thread, an inner clamping ring, a thoroughly-connecting hole, balls, a clamped slot, a rotatably-installed slot, rotatably-connected bolts, a first taper seat, a mounting plate, a keyhole, and a second taper seat. The fixing device for the drill pipe in the oil exploitation has the beneficial effects that the drill pipe is fixed together by the first taper seat and second taper seat, while ensuring that the drill pipe is fixed more firm and stable, the fixed platform and the base are fixed by multiple rotatably-connected bolts, and it is ensured thatthe device is more convenient and fast when the fixing device is installed or disassembled; when the drill pipe is connected in the fixedly-penetrated ring in a penetrating mode to perform a rotary drilling work, the inner clamping ring in the fixedly-penetrated ring is matched with multiple balls in the clamped slot to rotate lightly, under the action of drill pipe rotation, the inner clamping ring synchronizes with the drill pipe, and the service life of the drill pipe and the fixing device is prolonged; and the fixing device is convenient to operate, steady and firm, and all components areconnected flexibly.

Description

technical field [0001] The invention relates to a fixing device, in particular to a fixing device for drill pipes during oil exploitation, and belongs to the technical field of petroleum machinery applications. Background technique [0002] With the rapid development of people's life, oil extraction occupies a higher and higher position in life. The drill pipe is indispensable in the process of oil extraction. The drill bit on the drill pipe is used to drill into the ground, which is convenient for the staff to extract underground oil. During the working process of the drill pipe, the fixing device is used very frequently. Its main function is to penetrate and fix the drill pipe so as to avoid the vibration of the drill pipe during rotary drilling. [0003] However, there are still many deficiencies in the current fixing devices for drill pipes when used for oil extraction, such as the existing fixing devices are not firm enough to fix the drill pipes, and the installation o...

Problems solved by technology

[0003] However, there are still many deficiencies in the current fixing devices for drill pipes when used for oil extraction, such as the existing fixing devices are not firm enough to fix the drill pipes, and the installation or disassembly of the device is very inconvenient in use. When working in a fixed device, the friction loss between the drill pipe and the device is large, and the service life of the device and the drill pipe is low
