Embodiment Construction

[0009] refer to figure 1 , figure 2 , make the present invention.

[0010] A top hydraulically driven faucet is composed of a main structure, a hydraulic motor, a deceleration device, a sealing mechanism and a fastener. The main structure of the top hydraulically driven faucet includes a box body 1, a box cover 2, a lifting ring 3, a lifting ring pin 4, a flushing pipe and gooseneck assembly 5, and a center pipe 6. The hydraulic motor adopts a radial piston hydraulic motor 7 . The top hydraulically driven faucet adopts a top hydraulically driven form. The deceleration device of the top hydraulically driven faucet adopts a three-stage deceleration structure, which drives the center pipe to rotate at low speed, meets the torque requirement at low speed, and provides relatively large torque output. The reduction device of the water tap driven by the top hydraulic pressure comprises a primary driving gear 8, a primary driving gear shaft 9, a primary driven gear 10, a primary ...

Abstract

The invention discloses a swivel with top hydraulic driving, which is used for a top driving device of well drilling equipment, and consists of a main body structure, a hydraulic motor, a decelerating device, a sealing mechanism and a fastener, wherein the main body structure of the swivel with top hydraulic driving comprises a box body, a box cover, a lifting bail, a lifting bail pin, a wash pipe and gooseneck assembly and a central stem. A top hydraulic driving form and a three-stage decelerating structure are adopted for the swivel; the torque requirement at a low speed can be met; greater torque output is provided; moreover, the swivel has obvious advantages in aspects of the structural design of a component, well drilling shock resistance, the spark prevention of a working field, and the like; moreover, the structure is simple, and the production-manufacturing cost is lower.

Description

technical field [0001] The invention relates to a drilling equipment-power water tap, especially a top hydraulically driven water tap. Background technique [0002] At present, in oil and gas drilling operations, the rotational power of the drilling rig is increasingly provided by the driving device arranged on the top of the drilling rig, that is, the top drive. The top drive mainly adopts electric top drive. The power faucet is a key component of the top drive, mainly in the form of top electric drive. At present, the more common power faucets are mainly composed of a box body, a box cover, a lifting ring, a lifting ring pin, a flushing pipe and a gooseneck assembly, a central pipe, a motor and a reduction device, a sealing mechanism, and fasteners. Compared with the traditional driving form, the top drive has the advantages of fewer potential safety hazards, lower labor intensity of the operator, saving directional drilling time, and easy maintenance, so its popularity ...
