Problems solved by technology

[0002] At present, during the oil field drilling operation, the drill pipe is hoisted into the "mouse hole" by the well site worker and the wellhead worker with the cooperation of the electric or pneumatic small winch, and then directly connected to the single drill pipe by the top drive; , When drilling, the derrick worker on the second floor directly transfers the vertical root. This drilling method not only has high labor intensity and high risk, but more importantly, it sacrifices the advantages of fast drilling of the top drive vertical root and the work efficiency. lower

Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] The present invention includes a support frame 2 , a drill pipe horizontal conveying mechanism 1 , a drill pipe transfer mechanism 6 , a rathole clamp hand 3 , a hydraulic tong 5 , a vertical root lifting mechanism 7 and a vertical root discharge mechanism 9 .

[0035] The drill pipe horizontal conveying mechanism 1 is used for conveying the drill pipe on the ground to the bottom of the supporting frame 2 .

[0036] The drill pipe transfer mechanism 6 is used for lifting and horizontal transfer of the drill pipe; it is installed on the lower part of the support frame. Specifically, the drill rod transfer mechanism includes a fixed guide rail 6-9, a vertical guide rail 6-4, a support arm 6-3, a hydraulic cylinder A6-6, and a sliding trolley 6-7; the fixed guide rail 6-9 is vertical It is arranged and fixed on the bottom of the support frame 2; the vert...

Abstract

The invention provides an automatic racking device for a drill rod. A drill rod horizontal-conveying mechanism is adopted to convey one end of a first drill rod to be below a support frame, a drill rod transfer mechanism is used for inserting the lower end of the first drill rod into a mousehole clamp hand, and then a stand-rod lifting mechanism is used for lifting the first drill rod; meanwhile,the drill rod transfer mechanism is used for lifting a second drill rod, and the second drill rod is clamped by the mousehole clamp hand; the first drill rod descends, the lower end of the first drill rod contacts with the upper end of the second drill rod, a hydraulic tong fixedly arranged on a well platform connects the first drill rod with the second drill rod to form a double joint; thus three drill rods are connected into a three-joint unit; and a three-joint unit racking mechanism is used for transferring the three-joint unit into a driving or three-jointing box. The invention has a simple and reasonable design, realizes the automated operation of drill rod movement, three-jointing connection and three-jointing racking, is high in mechanization degree, reduces the labor intensity of workers, enhances the work efficiency, prevents people from being in direct contact with pipe fittings and enhances the safety and the reliability.

Description

technical field [0001] The invention relates to a petroleum machinery, in particular to an automatic discharge device for drilling rods. Background technique [0002] At present, during the oil field drilling operation, the drill pipe is hoisted into the "mouse hole" by the well site worker and the wellhead worker with the cooperation of the electric or pneumatic small winch, and then directly connected to the single drill pipe by the top drive; , When drilling, the derrick worker on the second floor directly transfers the vertical root. This drilling method not only has high labor intensity and high risk, but more importantly, it sacrifices the advantages of fast drilling of the top drive vertical root and the work efficiency. relatively low. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an automatic drill pipe discharge device with reasonable structure, easy manufacture and easy operation, so as...
