Embodiment 1

[0021] The step of continuing drill pipe 6 is:

[0022] 1. The gantry crane 4 lifts a drill pipe 6 from the drill pipe box 2 , the gantry crane 4 slides along the track 5 to the vicinity of the auxiliary support 7 , and places the drill pipe 6 on the auxiliary support 7 .

[0023] 2. The second support rod 16 pushes the frame 11 to move up, so that the lower surface of the inner hole of the bearing 12 is flush with the upper surface of the power catwalk 1, and the second support rod 16 stops and locks.

[0024] 3. The drill pipe 6 rolls onto the power catwalk 1 along the auxiliary bracket 7, and advances along the power catwalk 1 under the push of the pushing mechanism, passing through two bearings 12 in turn.

[0025] 4. When the pushing distance of the drill pipe 6 is about 1.2 times the length of the drill pipe, stop pushing, and the pushing mechanism reversely moves to the initial position.

[0026] 5. Repeat step 1, place a new drill pipe 6 on the power catwalk 1, and pu...

Abstract

The invention discloses a drill pipe and casing storage system, which includes a loading area, an unloading area and a power catwalk, wherein the loading area is provided with a drill pipe box, a casing box, and two One set of auxiliary brackets; two sets of auxiliary brackets are provided in the unloading area; the power catwalk runs through the loading area and the unloading area from between the auxiliary brackets, and there are at least two sets of connecting devices on the power catwalk, including racks deployed on the power catwalk And the second support bar used to support the frame, the top of the frame is flush with the upper surface of the power catwalk; bearings are fixed on the frame, a horizontal arm is arranged above the frame, and two vertical arms protrude downward from the center of the horizontal arm , the bottom of each vertical arm is equipped with a driven wheel, and the top is equipped with a driven wheel and a driving wheel connected by a conveyor belt; the horizontal arm is erected on the top of the first support rod; the first support rod and the second support rod are both adjustable in height Hydraulic telescoping rod. The invention is convenient to use and has broad application prospects.

Description

technical field [0001] The present invention relates to the technical field of machinery, more specifically to a drill rod storage device. Background technique [0002] In drilling engineering, it is necessary to continue to install drill pipes and casings as the drilling depth increases. The drill pipes are used for drilling, and the casings are used to reinforce the edges of the pipes. The drilling site needs to store a large number of drill pipes and casings. Due to the large quantity and heavy weight of drill pipes and casings, they are generally stored in drill pipe boxes and transported by transport vehicles. Drill pipes and casings often need to be transferred to the power catwalk by the gantry crane at the construction site, and then transported to the crane at the drilling head by the power catwalk. The connection of drill pipe and casing is also completed on the crane at the drilling head, but this process takes a lot of time. In order to make the degree of automa...
