[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] For a further understanding of the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0033] Refer to Figure 1 , a power catwalk machine, including a base 1, a driving mechanism 2 is arranged on the surface of the base 1, an auxiliary mechanism 3 is fixedly connected to one side of the surface of the base 1 close to the driving mechanism 2, and a transportation mechanism 5 is rotatably connected inside the driving mechanism 2.

[0034] Refer to Figure 1-2 , the driving mechanism 2 includes a protective plate 21 arranged on the surface of the base 1, two groups of bearing blocks 22 are arranged on the surface of the protective plate 21, and a first driving motor 23 is arranged on the outer surface of one of the bearing blocks 22.

[0035] Refer to Figure 3, the auxiliary mechanism 3 includes a heightening rod 31 fixedly connected to the surface of the base 1. An arc plate 35 is fixedly connected to the surface of the heightening rod 31. A fixing block 32 is fixedly connected to the surface of the arc plate 35. A conveying rod 33 is rotatably connected to the surface of the fixing block 32. A plurality of movable rods 34 are arranged on the surface of the arc plate 35 near the fixing block 32. A conveying arm 36 is rotatably connected to the surface of the movable rod 34. A pushing trolley body 37 is slidably connected to the surface of the conveying arm 36.

[0036] When the device operates, first convey the pipe column to the conveying rod 33 on the fixing block 32, and then convey the pipe column on the conveying rod 33 to the surface of the conveying arm 36. Start the pushing trolley body 37. The pushing trolley body 37 operates on the surface of the conveying arm 36, at the end of conveying the pipe column. Slide on the conveying arm 36 through the pushing trolley body 37 to convey the pipe column to be conveyed into the interior of the conveying mechanism 5.

[0037] Refer to Figures 4-6 , the conveying mechanism 5 includes a conveying cavity 51 rotatably disposed inside the bearing block 22. The surface of the conveying cavity 51 is fixedly connected to the output end of the first driving motor 23. A plurality of tapered holes 52 are circularly arrayed on the surface of the conveying cavity 51 near both sides of the two bearing blocks 22;

[0038] Refer to Figures 8-9 , a conveying component 53 is fixedly connected to the inner edge of the tapered hole 52. A plurality of transmission components 54 are further disposed inside the conveying cavity 51. A limiting block 55 is fixedly connected to the surface of the transmission component 54 near the conveying component 53, and the limiting block 55 is fixedly connected to the conveying component 53. A protective component 56 is fixedly connected to the surface of the transmission component 54 near the limiting block 55.

[0039] Refer to Figures 10-12 , a conveying cavity 531 is fixedly connected to the inside of the conveying component 53 through a load-bearing rod. A plurality of fitting holes 532 are formed on the surfaces of the conveying cavity 531 and the conveying component 53. A plurality of connecting blocks 535 are arranged on the surface of the conveying cavity 531 near the fitting holes 532. A movable plate 533 is slidably connected to the inside of the fitting hole 532 near the bottom surface of the conveying cavity 531. A rectangular hole 534 adapted to the middle tooth size of the movable plate 533 is formed inside the conveying cavity 531 near the movable plate 533. The other end of the connecting block 535 is fixedly connected to the inner wall of the conveying cavity 51.

[0040] When the pipe string is transported into the conical hole 52 on the transporting mechanism 5, the movable plate 533 is pushed forward by the rotation of the conveying wheel 546, reducing the gap generated during the transportation between the transporting mechanism 5 and the pushing trolley body 37. In actual use, the bottom surface of the movable plate 533 can be set as a tooth groove, and the conveying wheel 546 can still push the movable plate 533 forward. During installation, the movable plate 533 inside the transporting component 53 needs to always be horizontally aligned with the pushing trolley body 37 when approaching it.

[0041] Referring to Figures 7-8 , a second driving motor 541 is fixedly connected to the surface of the transmission component 54. The output end of the second driving motor 541 is fixedly connected to a first gear 542. A plurality of second gears 543 are rotatably connected to the side of the transmission component 54 away from the second driving motor 541. One end of each second gear 543 is fixedly connected to a rotating roller 544. A third gear 545 is rotatably connected to the side of the transmission component 54 close to the first gear 542. A conveying wheel 546 is fixedly connected to the surface of the third gear 545. The surface of the conveying wheel 546 meshes with the movable plate 533. A first synchronous belt 547 meshes with the surface of the second gear 543. One of the first synchronous belts 547 meshes with the second gear 543 and the first gear 542, and the other first synchronous belt 547 meshes with the second gear 543 and the third gear 545. The surfaces of two of the second gears 543 are connected by a second synchronous belt 548.

[0042] A circular hole 561 is formed on the surface of the protection component 56, and a protection cover 562 is arranged at the edge of the protection component 56 close to the circular hole 561.

[0043] When the pipe string slides close to the conical hole 52 on the conveying mechanism 5 through the conveying arm 36, the second drive motor 541 inside the conveying cavity 51 starts to operate. The rotation of the second drive motor 541 drives the conveying wheel 546 on the third gear 545 to start operating. The conveying wheel 546 rotates inside the rectangular hole 534 opened in the conveying component 53, pushing the movable plate 533 forward. At this time, the pipe string slides onto the surface of the movable plate 533 through the surface of the conveying arm 36. When the pipe string enters the inside of the conveying cavity 531, the second drive motor 541 on the transmission component 54 operates, causing the first gear 542 to transfer. When the pipe string enters the conical hole 52 through the conveying arm 36 and the movable plate 533, the rotation of the first gear 542 drives the two second gears 543 on both sides above the transmission component 54 to operate simultaneously. The second gears 543 on both sides of the transmission component 54 operate through the second synchronous belt 548, causing the rotating rollers 544 connected to the second gears 543 to roll and push the pipe string forward inside the conveying cavity 531. When the lower first synchronous belt 547 operates, it will drive the third gear 545 to move synchronously, causing the conveying wheel 546 connected to the third gear 545 to rotate and drive the movable plate 533 to move inside the cavity. The conveying component 53 can be extended or shortened according to the usage situation during use. The number of transmission components 54 inside the conveying mechanism 5 can be appropriately increased or decreased during use to adapt to the length of the conveying component 53. The first drive motor 23 on the bearing block 22 drives the conveying cavity 51 to rotate, enabling the conveying cavity 531 to rotate and lift to a suitable position corresponding to the drilling platform. Finally, the pipe string is transported out by the rotation of the rotating rollers 544 inside the conveying cavity 531. When a part of the pipe string enters the inside of the conveying cavity 531, the first gear 542 rotates through the second drive motor 541, driving the first synchronous belt 547 to operate. At this time, when the first synchronous belt 547 operates, the two second gears 543 on the surface of the transmission component 54 close to the first gear 542 rotate. The two second gears 543 on the transmission component 54 close to the protective cover 562 below are driven to rotate through the operation of the second synchronous belt 548, causing the four rotating rollers 544 on the surface of the second gears 543 to roll. The rotating rollers 544 rotate inside the fitting hole 532, rotating and pushing the pipe string inside the conveying cavity 531. At this time, the first drive motor 23 on the bearing block 22 starts to operate, and the rotation of the first drive motor 23 drives the conveying cavity 51 to operate, and the conveying cavity 51 rotates.Among them, the length of the second gear 543 is greater than that of the first gear 542 to adapt to the first gear 542 and the first synchronous belt 547 connected thereto. The third gear 545 and the first gear 542 are in the same horizontal position to ensure the normal operation of the first synchronous belt 547. The circular hole 561 of the protection component 56 is used to ensure that its conveying wheel 546 can pass through and rotate normally. The setting of the protection cover 562 is to prevent the upper part of the conveying wheel 546 from being interfered by external uncertain factors during operation.

[0044] Referring to Figure 1 , on one side of the surface of the base 1 away from the driving mechanism 2, a lifter body 4 is fixedly connected, and an anti-rust paint is sprayed on the surface of the lifter body 4.

[0045] When the height of the device is lower than the height of the platform, the overall height of the device can be adjusted by operating the lifter body 4 at the bottom, thereby raising the height of the base 1 and bringing the tapered hole 52 of the conveying mechanism 5 to the required height of the drilling platform.

[0046] On one side of the surface of the base 1 close to the driving mechanism 2, a counterweight 6 is provided.

[0047] When the pipe string being conveyed is input into the auxiliary mechanism 3, the device may tilt. At this time, the counterweight 6 is needed to balance and adjust the whole device.

[0048] Working principle: When the device is used, first adjust the height of the lift body 4 to adapt the output of the device to the drilling platform. After the adaptation, the pipe column to be transported is transported to the delivery rod 33 on the fixed block 32, and then the pipe column on the delivery rod 33 is transported to the surface of the delivery arm 36, and the push trolley body 37 is started. The push trolley body 37 operates on the surface of the delivery arm 36 and is at the end of the delivery pipe column. When the pipe column slides through the delivery arm 36 to the conical hole 52 near the delivery mechanism 5 , the second driving motor 541 inside the conveying cavity 51 starts to operate, and the rotation of the second driving motor 541 drives the conveying wheel 546 on the third gear 545 to start operating. The conveying wheel 546 rotates inside the rectangular hole 534 opened in the conveying component 53, pushing the movable plate 533 forward. At this time, the pipe column slides to the surface of the movable plate 533 through the surface of the conveying arm 36. The shape of the movable plate 533 is an arc shape, so as to adapt to the curved surface of the pipe column. When part of the pipe column enters the interior of the conveying cavity 531, the first gear The wheel 542 is rotated by the second driving motor 541, driving the first synchronous belt 547 to operate. At this time, when the first synchronous belt 547 is operating, the two second gears 543 on the surface of the transmission component 54 close to the first gear 542 rotate, and the two second gears 543 below the transmission component 54 close to the protective cover 562 are driven to rotate by the operation of the second synchronous belt 548, so that the four rotating rollers 544 on the surface of the second gear 543 roll, and the rotating rollers 544 rotate and operate inside the adapting hole 532 to rotate and push the pipe column inside the transport cavity 531. At this time, the first driving motor 23 on the bearing block 22 starts to operate, and the first driving motor 23 rotates to drive the conveying cavity 51 to operate. The conveying cavity 51 rotates, and one of the tapered holes 52 that is just horizontally aligned with the conveying arm 36 is rotated and raised to a suitable position corresponding to the drilling platform. At this time, the pipe column inside the conveying cavity 51 is pushed forward by the rotation of the rotating rollers 544 to reach a retrieval position close to the drilling platform, and finally the transported pipe column is subjected to subsequent operations.
