Example Embodiment

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

[0034] The invention includes a support frame 2, a drill rod horizontal conveying mechanism 1, a drill rod transport mechanism 6, a mouse hole clamp hand 3, a hydraulic tong 5, a standing root lifting mechanism 7 and a standing root discharging mechanism 9.

[0035] The drill rod horizontal conveying mechanism 1 is used to convey drill rods on the ground to the bottom of the support frame 2.

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

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...
