Referring to fig. 1, 2, and 4 to 6, in order to realize the transfer of the pipe column 800, in the embodiment of the present application, the catwalk apparatus further includes a first transfer mechanism 500, wherein the first transfer mechanism 500 is disposed on at least one side in the width direction of the catwalk frame 200. The first transfer mechanism 500 can be used to transfer the pipe column 800 between the catwalk frame 200 and the pipe rack 700 for accommodating the pipe column 800.

Typically, multiple tubular strings 800 may be arranged on the rake 700 for use in subsequent operations. The rake 700 may be disposed on one or both sides of the width direction of the catwalk frame 200, and may be specifically selected according to actual requirements. When the conveying speed of the pipe column 800 is high, the rack 700 may be provided on both sides of the catwalk frame 200 in the width direction, and accordingly, the first transfer mechanism 500 may be provided on both sides. Thus, the pipe columns 800 on the rake 700 on two sides can be respectively conveyed to the catwalk frame 200 by the first transfer mechanisms 500 on two sides, and then conveyed to the drill floor for use by the catwalk frame 200; or the pipe column 800 on the catwalk frame 200 is conveyed to the pipe racks 700 on both sides by the first transfer mechanisms 500 on both sides for storage. Of course, when the transport speed of the column 800 is low, the rake 700 and the first transfer mechanism 500 may be provided on one side in the width direction of the catwalk frame 200, and the column 800 may be transported from one side.

Referring to fig. 4 to 6, in the embodiment of the present application, the first transferring mechanism 500 includes a support 510, a second driving element 520, and a transferring arm 530, wherein a first end of the transferring arm 530 is rotatably connected to the support 510, the second driving element 520 is connected between the transferring arm 530 and the support 510, and the second driving element 520 is used for driving the transferring arm 530 to swing with respect to the support 510. Alternatively, the support 510 may be fixed to the base 100 to ensure stability of the first transfer mechanism 500. The support 510 is provided with a connecting lug, and the first end of the transferring arm 530 is connected with the connecting lug by a pin shaft, so that the transferring arm 530 can rotate relative to the support 510. The second driving member 520 may be a cylinder, an electric push rod or other direct driving members, and the second driving member 520 is connected to the middle portion of the transferring arm 530, so as to drive the transferring arm 530 to rotate around the pin.

In order to prevent the pipe column 800 from falling off from the first transfer mechanism 500 during the transfer process, in the embodiment of the present application, the second end of the transfer arm 530 is provided with the limiting claw 540, and the limiting claw 540 and the transfer arm 530 are disposed at an included angle, so that an accommodating space for accommodating the pipe column 800 is formed between the limiting claw 540 and the transfer arm 530. Optionally, the angle range of the included angle between the limiting claw 540 and the transferring arm 530 may be 60 ° to 150 °, including 60 °, 70 °, 90 °, 100 °, 120 °, 135 °, 150 °, and the like, and of course, other angles meeting the requirement may also be included. Based on the above arrangement, when the first transfer mechanism 500 transfers the tubular column 800, the tubular column 800 is restricted in the accommodating space by the limiting claw 540 and the transfer arm 530, so that the tubular column 800 is not easily separated from the accommodating space, thereby ensuring normal transfer of the tubular column 800.

The specific working process of the first transfer mechanism 500 in the embodiment of the present application is as follows:

in the retracted state, as shown in fig. 4, the stopping pawl 540 is in a low position, and the stopping pawl 540 is positioned below the pipe column 800 carried on the pipe rack 700; then, under the driving action of the second driving member 520, the transfer arm 530 rotates towards the direction away from the support 510, and in the process, the limiting claw 540 gradually ascends, so that the pipe column 800 on the pipe rack 700 can be lifted and carried in the accommodating space.

In the lifted state, as shown in fig. 6, the position-limiting claw 540 is located at a high position, and the second end of the transferring arm 530 is higher than the first end, so that the pipe column 800 in the accommodating space can roll along the transferring arm 530 towards the catwalk frame 200, and can move to the catwalk frame 200 to be conveyed to the drill floor through the catwalk frame 200.

In the receiving state, as shown in fig. 5, the position-limiting claw 540 is located at the middle position, and the second end of the transfer arm 530 is lower than the first end, so that the pipe column 800 in the catwalk frame 200 can roll along the transfer arm 530 towards the position-limiting claw 540, and can move to the accommodating space; then, the transfer arm 530 is driven by the second driving member 520 to rotate in the opposite direction, so that the stopping claw 540 descends, and the pipe column 800 in the accommodating space can be placed on the pipe rack 700. It should be noted that the pipe column 800 in the catwalk frame 200 can move the pipe column 800 to the first end of the transfer arm 530 by other means, which will be described in detail later.

Referring to fig. 1, fig. 2, fig. 7 to fig. 9, and fig. 10, in order to enable the pipe column 800 to enter the bearing groove 210 of the catwalk frame 200 or to enable the pipe column 800 to be separated from the bearing groove 210, in the embodiment of the present application, the catwalk apparatus further includes a second transfer mechanism 600, wherein a transfer end of the second transfer mechanism 600 is movable up and down with respect to the bearing surface of the catwalk frame 200. Thus, when the transfer end is in the raised state, the column 800 is carried on the transfer end, and when the transfer end is in the lowered state, the column 800 is carried on the carrying surface. Based on the above arrangement, the transfer end can lift the column 800, so that the column 800 conveyed from the first transfer mechanism 500 can be received and placed in the load-bearing groove 210, and the column 800 in the transfer groove can be jacked up and placed into the first transfer mechanism 500.

Referring to fig. 7 to 9 and 10, in some embodiments, the second transfer mechanism 600 includes a first lifting member 610, a second lifting member 620, and a carrier 630, where the carrier 630 is the transfer end. In order to install the transfer end, the embodiment of the present application provides the receiving groove 220 extending in the width direction of the catwalk frame 200, the carrier 630 is disposed in the receiving groove 220 in a liftable manner, the first lifter 610 is connected to one end of the carrier 630, and the second lifter 620 is connected to the other end of the carrier 630. Thus, the posture of the bearing piece 630 can be adjusted through the respective lifting conditions of the first lifting piece 610 and the second lifting piece 620, so as to meet the requirements under different working conditions.

In the case where one of the first and second lifters 610 and 620 is in the raised state, the carrier 630 is disposed to be inclined in the width direction of the catwalk frame 200, and specifically, when the first lifter 610 is raised, one end portion of the carrier 630 to which the first lifter 610 is connected may be raised higher than the other end portion, so that the pipe column 800 carried on the carrier 630 may be rolled from the one end portion to which the first lifter 610 is connected to the other end portion to which the second lifter 620 is connected. Conversely, when the second lifter 620 is raised, the tubular string 800 carried on the carrier 630 may be rolled from one end to which the second lifter 620 is connected to the other end to which the first lifter 610 is connected.

With both the first and second lifters 610 and 620 in the raised state, the string 800 is carried on the carrier 630, that is, the string 800 is jacked up by the carrier 630 to be located above the carrier tub 210.

With both the first lifting member 610 and the second lifting member 620 in the lowered state, the tubular string 800 is carried on the carrying surface, i.e., the carrying member 630 is retracted into the receiving groove 220, such that the tubular string 800 is located in the carrying groove 210.

The specific working process of the second transfer mechanism 600 in the embodiment of the present application is as follows:

as shown in fig. 8, when the pipe column 800 is loaded on the catwalk frame 200, the pipe column 800 conveyed from the first transfer mechanism 500 is rolled onto the carrier 630 via the transfer arm 530, and at this time, the first lifting member 610 is in a raised state, and the second lifting member 620 is in a lowered state (the first transfer mechanism 500 and the first lifting member 610 are located on the same side in the width direction of the catwalk frame 200), and at this time, one end portion of the carrier 630 connected to the first lifting member 610 is substantially level with or slightly lower than the first end of the transfer arm 530, and as the transfer arm 530 is lifted upward, the pipe column 800 in the accommodation space is rolled onto the carrier 630 by the transfer arm 530. After the above process is completed, the first elevating member 610 descends to fully retract the carrier 630 into the receiving groove 220, as shown in fig. 9, so that the tubular string 800 is placed in the receiving groove 210, and the tubular string 800 can be conveyed to the drill floor through the catwalk frame 200.

As shown in fig. 7, in the case of moving the pipe column 800 in the catwalk frame 200 out of the carrying tank 210, the first and second lifters 610 and 620 are simultaneously raised, the tubular string 800 in the load-bearing trough 210 is jacked up by the carrier 630, and the carrier 630 is substantially level with or slightly above the first end of the transfer arm 530, at the same time, the second lifting member 620 rises slightly lower than the height at which the first lifting member would rise (the first transfer mechanism 500 and the second lifting member 620 are located on the same side of the width direction of the catwalk frame 200), at this time, the end of the carrier 630 away from the transfer arm 530 is slightly higher, the pipe column 800 on the carrier 630 can easily roll onto the transfer arm 530, and the pipe column 800 on the catwalk frame 200 is transported to the first transfer mechanism 500 by the second transfer mechanism 600, and finally transported to the rack 700 by the first transfer mechanism 500 for storage.
