[0002] The pipe string automatic transportation device is commonly known as a power catwalk, which is a transportation device in oil and gas drilling and production machinery. The pipe string automatic transportation device includes a ramp, a base, and a traction system for transporting the pipe string. According to the different heights of the drill floor, the pipe string automatic transportation device is divided into a low drill floor power catwalk and a high drill floor power catwalk.

[0003] Currently, during the operation of tripping drill pipes, tubing and other pipe strings in the well, it mainly relies on manual labor plus crowbars or forklifts to push the pipe strings on the two side pipe racks onto the power catwalk, tie a steel wire rope to one end of the pipe string, and then use a pneumatic or hydraulic winch on the workover rig to lift one end of the pipe string and lift it along the slideway to the operation platform. This is time-consuming and laborious, and the work efficiency is low. When the pipe string has a large mass, the inertia force is also large, and it is prone to unsafe accidents.

[0004] To solve the above problems, the invention with the publication number CN112983309B and the invention name of "Pipe String Automatic Transportation Device" discloses a pipe string automatic transportation device, which uses upper and lower tractors to control the upper hook, automatically lock and unlock the upper hook through mechanical linkage, so as to improve the reliability of the transfer of the pipe string between the upper tractor and the lower tractor. However, the upper and lower pipe strings still require manual operation, with low efficiency and insecurity, and the operation is cumbersome. The invention with the publication number CN103696710B and the invention name of "Well Operation Pipe String Transportation Device" discloses a well operation pipe string transportation device, which has high efficiency and reduces labor costs. However, it uses hydraulic tools, is prone to oil leakage and has high danger, and can only transport one pipe string at a time, with low efficiency and inconvenient operation. Summary of the Invention

These are only for the convenience of describing the invention and simplifying the description, and are not to be construed as limitations on the invention.

[0029] Refer to Figure 1 , the overall structure of the present invention includes a ramp assembly and a base assembly,

[0030] Refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 , the structure of the ramp assembly is as follows: it includes a ramp support frame 1 as the main load-bearing component. At the top end of the upper surface of the ramp support frame 1, a slideway support base 18 is hinged. On the upper surface of the slideway support base 18, a slideway support 14 is formed. Along the longitudinal center line on the upper surface of the slideway support 14, there is a slideway two 15. Along the longitudinal center line on the upper surface of the slideway two 15, there is an arc-shaped groove 16 (the arc-shaped groove 16 is used for placing pipe columns). At the outer edge of the lower end of the slideway two 15, there is a limit groove 21 (the limit groove 21 corresponds to the pipe column); a sliding shaft 19 is slidably connected to the inner cavity of the slideway support base 18. At one end of the outer side of the slideway support base 18, a support frame 17 is hinged. The bottom end of the support frame 17 is hinged on the rotating shaft of a rotating motor (referred to as motor one, not shown in the drawings) in the ramp support frame 1; at the end of the bottom surface of the lower inclined plane of the slideway support 14, a stop block 20 is fixed, and the stop block 20 corresponds to the sliding shaft 19 to prevent the sliding shaft 19 from coming out.

[0031] Refer to Figure 7 , Figure 8 , Figure 9 , Figure 10 , the structure of the base assembly is as follows: it includes a slideway one 2. Along the longitudinal center line on the upper surface of the slideway one 2, there is a V-shaped chute 3. In the middle section center line of the V-shaped chute 3, there is a longitudinal slit 4. A push block 9 is slidably arranged in the slit 4. The push block 9 is equipped with its own traction motor (referred to as motor two). At the front end of the push block 9, there is a push plate 10. The bottom end of the push plate 10 is fixedly connected to a support plate 11. On the upper surface of the support plate 11, in the part where the push plate 10 faces forward, there is an anti-slip limit member 12.

[0032] Refer to Figure 8 , on the upper surface of the slideway one 2 on both sides outside the V-shaped chute 3, there are respectively transverse seesaws 5. The bottom surfaces of the two seesaws 5 on both sides are jointly connected to a lifting mechanism 6. At the same time, in the gap between one seesaw 5 and the V-shaped chute 3, there is an inclined strut 7; the lifting mechanism 6 is upwardly connected to two lifting shafts, and each lifting shaft is respectively hinged to the bottom surface of one seesaw 5 on one side to respectively control the lifting of the two seesaws 5 on both sides to drive the pipe column to roll so that the pipe column reaches the center line position of the V-shaped chute 3.

[0033] Refer to Figure 6 , on both sides of the main body of the slideway one 2, there are a plurality of wheels 13. Inside the slideway one 2, there is a driving motor (referred to as motor three). The driving motor is drivingly connected to the wheels 13 and is used to adjust the position of the overall structure of the present invention device and the drilling platform.

[0034] Refer to Figure 11 , arc-shaped protrusions are provided along both edges of the groove of the arc-shaped groove 16, which are used to limit the position of the end of the pipe column during pipe column transportation, so that it will not slide and shift.

[0035] Refer to Figure 1 、 Figure 2 、 Figure 7 , two limit posts 22 are provided longitudinally along the upper surface edge of the first slideway 2. The distance between the two limit posts 22 is slightly less than the length of a pipe column, which is used to limit the placement position of the pipe column and can prevent the pipe column from rolling down the first slideway 2.

[0036] Under the cooperation of the seesaw 5 and the diagonal strut 7, they are connected end to end and are pushed forward by the pushing block 9 at the middle position of the V-shaped chute 3.

[0037] See Figure 9 , the surface of the push plate 10 that pushes the pipe column is inclined, and limit protrusions 23 corresponding to the pipe column are provided. The limit protrusions 23 cooperate with the anti-slip limit member 12 to jointly limit the position of the end of the pipe column and prevent the pipe column from sliding and falling off during the pushing process.

[0038] Refer to Figure 1 , the ground pipe column conveying method of the present invention uses the above-mentioned device of the present invention and is implemented according to the following steps:

[0039] Step 1: Move the pipe column onto the first slideway 2, start the lifting mechanism 6, and the outer ends of the seesaws 5 on both sides are respectively lifted, driving the pipe column to fall into the center line position of the V-shaped chute 3, and fixing the end of the pipe column on the pushing block 9;

[0040] Step 2: Start the traction motor, and the pushing block 9 pushes the pipe column to slide forward along the V-shaped chute 3. When the front end of the pipe column reaches the limit groove 21 at the end of the second slideway 15, due to the circular arc guiding and assisting effect, the pipe column starts to slide upward along the arc-shaped groove 16;

[0041] Step 3: When the pushing block 9 touches the limit groove 21 and stops moving forward, it returns to the initial position under the action of the traction motor. At this time, the entire pipe column completely enters the arc-shaped groove 16;

[0042] Step 4: Start the rotation motor in the ramp support frame 1. The rotating shaft of the rotation motor drives the support frame 17 to start rotating clockwise. The support frame 17 drives the lower end of the slideway support base 18 to lift upward, and the slideway support base 18 simultaneously slides forward along the sliding shaft 19 (that is, the slideway support base 18 rotates and extends forward at the same time) until the sliding shaft 19 contacts the stop block 20 and is limited. The slideway support base 18 just reaches the horizontal position. During this period, since the limit groove 21 holds the lower end of the pipe column, the pipe column will not slide down and fall. At this time, the arc-shaped groove 16 on the slideway support base 18 is at the same horizontal position as the pipe column receiving platform;

[0043] Step 5: Hook the pipe string to the traction assembly on the takeover pipe string platform, and move the pipe string forward to disengage from the arc-shaped groove 16, completing the conveyance of one pipe string.
