Description

Technical Field

[0001] The invention relates to the field of oil drilling tools, in particular to a power catwalk and conveying equipment. Background Art

[0002] During oil drilling, a large number of cylindrical tubular tools need to be connected or disconnected (make-up / break-out), such as drill pipes, casing (about 9m to 13m long), etc. The pipe string needs to be transported from the ground pipe rack to the drilling floor of the drilling rig for connection, and the length can reach tens of thousands of meters. When the pipe string is taken out from the wellhead, it needs to be disassembled and transported from the drilling floor back to the drill pipe rack.

[0003] Transporting pipe strings is a highly dangerous and labor-intensive job. Some pipe strings weigh up to 4.5 tons. In order to improve the automation and efficiency of oil drilling equipment and reduce the danger during drilling, power catwalks are generally used to transport pipe strings. This requires the power catwalk to control the movement trajectory of the pipe string during the transportation process, otherwise the equipment will fail or even cause danger.

[0004] The feeding and discharging mechanism of the power catwalk is used to flip the pipe string from the pipe racks on both sides of the catwalk body to the V-shaped support beam in the middle of the catwalk body; or, it is used to flip the pipe string on the V-shaped support beam in the middle of the catwalk body to the pipe racks on both sides. Through the action of the feeding and discharging mechanism of the power catwalk, the power catwalk can further transport the pipe string to the drilling floor; or, further arrange the pipe string on the pipe racks on both sides of the catwalk body.

[0005] At present, the feeding and discharging mechanisms commonly used on power catwalks are as follows: Figure 1 As shown, the upper flap is lifted by the oil cylinders on both sides to enable the pipe string to enter and exit the pipe rack. This mechanism has the following shortcomings: 1. In order to minimize the weakening of the strength of the upper beam of the base, the oil cylinders on both sides are arranged as close to the middle of the base as possible, and the stranding area (the area where the mechanism flap sinks below the upper surface of the base during operation is called the stranding area. When the pipe string rolls to this area, there is no inclined support, and the pipe string rolls on the upper surface of the base by inertia) is lengthened. When the pipe string is fed, it can only rely on inertia to cross the stranding area. Because the V-shaped support beam needs to lift the pipe string from the base to the drilling platform, there is a large gap between the base and the base. The risk of the pipe string being stranded in this gap is very high; 2. In order to minimize the stranding area, the oil cylinder on the discharge side of the feeding and discharging mechanism needs to be as close to the V-shaped support beam as possible, which has to weaken the volume and weight of the main beam on the base, seriously affecting the bearing capacity of the base. Summary of the invention

[0006] The purpose of the invention is to provide a powered catwalk and conveying equipment, which solves the problem that the prior art cannot balance the load-bearing capacity of the flap and reduce the stranded area.

[0007] The present invention is implemented as follows: a conveying device for a power catwalk is used to convey a pipe body between a first platform and a second platform. The conveying device is arranged between the first platform and the second platform, and includes a guide plate, a first mounting seat, a second mounting seat, a driving mechanism and a connecting rod. The first end of the guide plate is movably connected to the first mounting seat, and the second end of the guide plate is movably connected to the second mounting seat through a connecting rod. The driving mechanism is used to drive the end of the guide plate to move.

[0008] The pipe string is placed on the first platform, and after the first platform is tilted, it falls onto the guide plate in the conveying equipment. The guide plate is tilted, and the pipe string falls onto the second platform. The pipe string is then conveyed to the drilling platform by the lifting of the second platform. In this process, if the force point used to drive the first platform to tilt is set close to the guide plate, the guide plate has a strong load-bearing capacity, but there is a large stranded area at the end when it is tilted. If the force point is close to the end, the problem of reducing the stranded area is solved, but the load-bearing of the guide plate will be reduced. Therefore, it is difficult to balance the load-bearing of the guide plate and the problem of the stranded area between the guide plate and the second platform. In the present invention, the first end of the guide plate is movably connected to the first mounting seat, and the second end is movably connected to the second mounting seat by a connecting rod. When the guide plate ends move, the guide plate, the guide plate and the first mounting seat movably connected end, and the guide plate and the second mounting seat movably connected end through the connecting rod form a crank slider mechanism during the movement of the guide plate end. Specifically, when the first end of the guide plate rises through the driving mechanism, the guide plate tilts toward the second platform. During the tilting process, the guide plate rotates around the connection between the second end and the connecting rod. Since it rotates around the end, the stranding area between the guide plate and the second platform is controlled within a smaller range. At the same time, the second mounting seat can be set close to the middle of the guide plate. The second mounting seat is connected to the guide plate through a connecting rod, which will not only not affect the movement of the guide plate, but also will not affect the load-bearing capacity of the guide plate, which well solves the problems of the guide plate load-bearing capacity and the stranding area in the prior art.

[0009] When the first end of the guide plate close to the first platform is moved by the driving mechanism, the guide plate, the movable connection end of the guide plate and the first mounting seat, and the guide plate and the second mounting seat are connected through the connecting rod, forming a crank slider mechanism during the movement of the guide plate end; when the second end of the guide plate close to the second platform is moved by the driving mechanism, the guide plate, the movable connection end of the guide plate and the first mounting seat, and the guide plate and the second mounting seat are connected through the connecting rod, forming a crank slider mechanism, which can reduce the problem of the stranded area during loading and unloading, and solve the load-bearing problem of the guide plate.

[0010] A further technical solution of the present invention is: the driving mechanism comprises a first driving mechanism and a second driving mechanism, and one end of the first driving mechanism is movably connected to the first mounting seat and the guide plate.

[0011] A further technical solution of the present invention is: a first roller is provided at the other end of the first driving mechanism, the first roller is slidably connected to the first mounting seat, and the first roller is also hinged to the guide plate.

[0012] The first driving mechanism is slidably connected to the first mounting seat through a roller, and the other end of the guide plate is movably connected to the second mounting seat through a connecting rod to form a crank slider mechanism.

[0013] A further technical solution of the present invention is: one end of the second driving mechanism is hinged to the second mounting seat, and the other end of the second driving mechanism is movably connected to the second mounting seat and the connecting rod respectively.

[0014] A further technical solution of the present invention is: a second roller is provided at the other end of the second driving mechanism, the second roller is slidably connected to the second mounting seat, and the second roller is also hinged to one end of the connecting rod.

[0015] A further technical solution of the present invention is: one end of the connecting rod is movably connected to the guide plate, and the other end of the connecting rod is movably connected to the second roller of the second driving mechanism.

[0016] The second driving mechanism is connected to the second mounting seat through a roller, and the roller is connected to the guide plate through a connecting rod. The first end of the guide plate is movably connected to the first mounting seat to form a crank slider mechanism.

[0017] A further technical solution of the present invention is that the connecting rod is L-shaped.

[0018] A further technical solution of the present invention is: a first guide groove is provided on the first mounting seat, and the first end of the guide plate can slide up and down along the first guide groove.

[0019] When the first driving mechanism drives the guide plate to slide up and down along the first guide groove, the second end of the guide plate is lifted by a certain distance through the follow-up movement of the connecting rod.

[0020] A further technical solution of the present invention is that the first guide groove is inclined away from the second mounting seat.

[0021] When the first end of the guide plate rises along the first guide groove, the second end of the guide plate tilts downward under the action of the connecting rod, and at the same time, the second end of the guide plate will be lifted upward above the second platform, further ensuring that the pipe body can smoothly fall from the guide plate to the second platform. Compared with the prior art in which the first end of the guide plate is driven to tilt, the second end of the guide plate will be lower than the second platform, causing the pipe body to further run aground. The technical solution of the present invention solves this problem very well. When the first guide groove is tilted, it can be achieved that when the first driving mechanism is in action, the second end of the guide plate can be driven to lift a greater distance through the follow-up of the connecting rod, and the anti-running effect is better.

[0022] A further technical solution of the present invention is that a second guide groove is provided on the second mounting seat, and the second end of the guide plate can slide up and down along the second guide groove.

[0023] The present invention also provides a power catwalk, including a connecting seat, a liftable first platform, a liftable second platform and a conveying device, wherein the second platform and the conveying device are placed on the connecting seat, and the first platform is placed on one side of the connecting seat and docked with the conveying device.

[0024] The pipe body is generally placed on the first platform. By lifting and lowering the first platform, it tilts toward the conveying equipment, and the pipe body falls into the conveying equipment. The conveying equipment tilts toward the second platform, and the pipe body falls into the second platform. The second platform lifts and conveys the pipe body to the drilling platform to complete the feeding. When discharging is required, the action is reversed.

[0025] A further technical solution of the present invention is: a crossbeam is provided on the connecting seat, and the conveying equipment is connected to the crossbeam.

[0026] The crossbeam design on the connecting seat further increases the stability of the structure.

[0027] A further technical solution of the present invention is that the upper surface of the second platform is a concave structure.

[0028] The second platform with a concave structure can ensure the stability of the pipe body during the transportation process to the drilling platform.

[0029] The beneficial effects of the present invention are as follows: In the present invention, the first end of the guide plate is movably connected to the first mounting seat, and the second end is movably connected to the second mounting seat through a connecting rod. When the driving mechanism drives the end of the guide plate to move, the guide plate, the movably connected end of the guide plate and the first mounting seat, and the movably connected end of the guide plate and the second mounting seat are connected through the connecting rod. During the movement of the end of the guide plate, a crank slider mechanism is formed. Specifically, when the first end of the guide plate rises through the driving mechanism, the guide plate tilts toward the second platform. During the tilting process, the guide plate rotates around the connection between the second end and the connecting rod. Since it rotates around the end, the stranding area between the guide plate and the second platform is controlled within a smaller range. At the same time, the second mounting seat can be arranged close to the middle of the guide plate. The second mounting seat is connected to the guide plate through a connecting rod, which not only does not affect the movement of the guide plate, but also does not affect the load-bearing capacity of the guide plate, and well solves the problems of the load-bearing capacity and stranding area of ​​the guide plate in the prior art.

[0045] Embodiment 1:

[0046] Figure 2-5 A conveying device for a powered catwalk is shown, which is used to convey a pipe body between a first platform 7 and a second platform 8. The conveying device is arranged at intervals between the first platform 7 and the second platform 8, and includes a guide plate 1, a first mounting seat 2, a second mounting seat 3, a driving mechanism 4 and a connecting rod 5. The first end of the guide plate 1 is movably connected to the first mounting seat 2, and the second end of the guide plate 1 is movably connected to the second mounting seat 3 through the connecting rod 5. The driving mechanism 4 is used to drive the end of the guide plate 1 to move.

[0047] The pipe string is placed on the first platform 7, and the first platform 7 falls onto the guide plate 1 in the conveying equipment after being tilted. The guide plate 1 tilts, and the pipe string falls onto the second platform 8, and then the pipe string is transported to the drilling platform by lifting the second platform 8. In this process, if the force point used to drive the first platform 7 to tilt is set close to the guide plate 1, the guide plate 1 has a strong load-bearing capacity, but there is a large stranded area 10 at the end when it is tilted. If the force point is close to the end, although the problem of reducing the stranded area 10 is solved, the load-bearing capacity of the guide plate 1 will be reduced. Therefore, it is difficult to balance the load-bearing capacity of the guide plate 1 and the problem of the stranded area between the guide plate 1 and the second platform 8. In the present invention, the first end of the guide plate 1 is movably connected to the first mounting seat 2, and the second end is movably connected to the second mounting seat 3 through the connecting rod 5. When the driving mechanism 4 drives the guide plate When the end of the guide plate 1 moves, the guide plate 1, the movably connected end between the guide plate 1 and the first mounting seat 2, and the movably connected end between the guide plate 1 and the second mounting seat 3 are formed through the connecting rod 5. A crank slider mechanism is formed during the movement of the end of the guide plate 1. Specifically, when the first end of the guide plate 1 rises through the driving mechanism 4, the guide plate 1 tilts toward the second platform 8. During the tilting process, the guide plate 1 rotates around the connection between the second end and the connecting rod 5. Since it rotates around the end, the stranding area 10 between the guide plate 1 and the second platform 8 is controlled within a smaller range. At the same time, the second mounting seat 3 can be arranged close to the middle of the guide plate 1. The second mounting seat 3 is connected to the guide plate 1 through the connecting rod 5, which will not only not affect the movement of the guide plate 1, but also will not affect the load-bearing of the guide plate 1, and well solves the problems of the load-bearing and stranding area 10 of the guide plate 1 in the prior art.

[0048] When the first end of the guide plate 1 close to the first platform 7 is moved by the driving mechanism 4, the guide plate 1, the movably connected end of the guide plate 1 and the first mounting seat 2, and the movably connected end of the guide plate 1 and the second mounting seat 3 are formed through the connecting rod 5 during the movement of the end of the guide plate 1. When the second end of the guide plate 1 close to the second platform 8 is moved by the driving mechanism 4, the guide plate 1, the movably connected end of the guide plate 1 and the first mounting seat 2, and the movably connected end of the guide plate 1 and the second mounting seat 3 are formed through the connecting rod 5. A crank slider mechanism, when loading and unloading materials, can reduce the problem of the stranded area 10, and at the same time solve the load-bearing problem of the guide plate 1.

[0049] In this embodiment, the driving mechanism 4 includes a first driving mechanism 41 and a second driving mechanism 42. One end of the first driving mechanism 41 is hinged to the first mounting seat 2 and the other end is slidably connected to the first mounting seat 2 through a first roller 43. The first roller 43 is connected to the guide plate 1.

[0050] The other end of the first driving mechanism 41 is slidably connected to the first mounting seat 2 through a roller 43, and the other end of the guide plate 1 is movably connected to the second mounting seat 3 through a connecting rod 5, forming a crank slider mechanism.

[0051] In this embodiment, one end of the second driving mechanism 2 is hinged to the second mounting seat 3 and the other end is slidably connected to the second mounting seat 3 via a second roller 44 , and the second roller 44 is rotatably connected to the connecting rod 5 .

[0052] The other end of the second driving mechanism 42 is slidably connected to the second mounting seat 3 through the second roller 44. At the same time, the second roller 44 is connected to the guide plate 1 through the connecting rod 5. The first end of the guide plate 1 is movably connected to the first mounting seat 2 to form a crank slider mechanism.

[0053] In this embodiment, Figure 4 In the embodiment, a first guide groove 21 is formed on the first mounting seat 2, and a first roller 43 is hinged on the cylinder rod end of the feed cylinder in the first driving mechanism 41. The feed cylinder can slide freely in the first guide groove 21 of the first mounting seat 2 through the first roller 43, thereby realizing the lifting and retraction of the guide plate 1 by the feed cylinder. At this time, the discharge cylinder in the second driving mechanism 42 is retracted into position and does not move. The first guide groove 21 and the first roller 43 on the first mounting seat 2, the guide plate 1 and the connecting rod 5 together constitute a crank slider mechanism, which can be driven back and forth by the feed cylinder.

[0054] In this embodiment, Figure 5 In the embodiment, the second mounting seat 3 is also provided with a second guide groove 31, and a second roller 44 is hinged on the end of the discharge cylinder rod. The discharge cylinder can slide freely in the second guide groove 31 through the second roller 44, thereby realizing the lifting and retraction of the connecting rod 5 by the discharge cylinder. At this time, the feed cylinder in the first driving mechanism 41 is retracted to its position and does not move. The second guide groove 31 of the second mounting seat 3 and the second roller, the connecting rod 5 and the guide plate 1 together constitute a crank slider mechanism, which can be driven back and forth by the discharge cylinder.

[0055] When the first end 11 of the guide plate 1 rises along the first guide groove 21, the second end 12 of the guide plate will be lifted up a certain distance under the action of the connecting rod 5 while the guide plate 1 is tilted, so that the guide plate 1 is higher than the second platform 8, further ensuring that the tube body can smoothly fall from the guide plate 1 to the second platform 8. Compared with the prior art in which the first end 11 of the guide plate 1 is driven to tilt, the second end of the guide plate 1 will be lower than the second platform 8, causing the tube body to be further stranded, the technical solution of the present invention can solve this problem well.

[0056] In this embodiment, the first mounting seat 2 is provided with a first guide groove 21 for the first roller 43 to slide.

[0057] In this embodiment, the first driving mechanism 41 includes a feeding cylinder.

[0058] In this embodiment, the second driving mechanism 42 includes a discharge cylinder.

[0059] In this embodiment, the second mounting seat 3 is provided with a second guide groove 31 , and the second roller 44 slides in the second guide groove 31 .

[0060] Embodiment 2

[0061] On the basis of the first embodiment, in this embodiment, the connecting rod 5 is L-shaped.

[0062] Embodiment 3

[0063] On the basis of the first or second embodiment, in this embodiment, the first guide groove 21 is inclined away from the second mounting seat 3 , and the first end 11 of the guide plate 1 can slide along the first guide groove 21 .

[0064] When the first end 11 of the guide plate 1 rises along the first guide groove 21, the second end 12 of the guide plate 1 will be lifted up a higher distance under the action of the connecting rod 5 while the guide plate 1 is tilted, so that the guide plate 1 is higher than the second platform 8, further ensuring that the tube body can smoothly fall from the guide plate 1 to the second platform 8. Compared with the prior art in which the first end 11 of the guide plate 1 is driven to tilt, the second end 12 of the guide plate 1 will be lower than the second platform 8, causing the tube body to be further stranded, the technical solution of the present invention can better solve this problem.

[0065] Embodiment 4:

[0066] like Figure 2-5 A powered catwalk is shown, comprising a connecting seat 6, a liftable first platform 7, a liftable second platform 88 and a conveying device 9 as described in any one of embodiments one to three, wherein the second platform 88 and the conveying device 9 are placed on the connecting seat 6, and the first platform 7 is placed on one side of the connecting seat 6 and docked with the conveying device 9.

[0067] The pipe body is generally placed on the first platform 7. By lifting and lowering the first platform 7, it tilts toward the conveying equipment, and the pipe body falls into the conveying equipment. The conveying equipment tilts toward the second platform 8, and the pipe body falls into the second platform 8. The second platform 8 lifts and conveys the pipe body to the drilling platform to complete the feeding. When discharging is required, the action is reversed.

[0068] In this embodiment, a crossbeam 61 is provided on the connecting seat 6 , and the conveying device 9 is connected to the crossbeam 61 .

[0069] The design of the crossbeam 61 on the connecting seat 6 further increases the stability of the structure.

[0070] In this embodiment, the upper surface of the second platform 8 is a concave structure.

[0071] The second platform 8 with a concave structure can ensure the stability of the pipe body during the transportation process to the drilling platform.

[0072] In this embodiment, the second platform 8 is a V-shaped support beam.

[0073] In this embodiment, the first platform 7 and the conveying equipment are symmetrically installed on both sides of the second platform 8 .

[0074] The working principle of the present invention is as follows: the pipe column is placed on the first platform 7, and the first platform 7 falls onto the guide plate 1 in the conveying equipment after being tilted. The guide plate 1 tilts, and the pipe column falls onto the second platform 8, and then the pipe column is transported to the drilling platform by the lifting of the second platform 8. In this process, if the force point used to drive the first platform 7 to tilt is set close to the guide plate 1, the guide plate 1 has a strong load-bearing capacity, but there is a large stranded area at the end when it is tilted. If the force point is close to the end, the problem of reducing the stranded area is solved, but the load-bearing capacity of the guide plate 1 will be reduced. Therefore, it is difficult to balance the load-bearing capacity of the guide plate 1 and the problem of the stranded area between the guide plate 1 and the second platform 8; in the present invention, the first end 11 of the guide plate 1 is movably connected to the first mounting seat 2, and the second end 12 is movably connected to the second mounting seat 3 through the connecting rod 5, and when the driving mechanism 4 drives When the end of the guide plate 1 moves, the guide plate 1, the movably connected end of the guide plate 1 and the first mounting seat 2, and the movably connected end of the guide plate 1 and the second mounting seat 3 are connected through the connecting rod 5. A crank slider mechanism is formed during the movement of the end of the guide plate 1. Specifically, when the first end 11 of the guide plate 1 rises through the driving mechanism 4, the guide plate 1 tilts toward the second platform 8. During the tilting process, the guide plate 1 rotates around the connection between the second end 12 and the connecting rod 5. Since it rotates around the end, the stranding area between the guide plate 1 and the second platform 8 is controlled within a smaller range. At the same time, the second mounting seat 3 can be set close to the middle of the guide plate 1. The second mounting seat 3 is connected to the guide plate 1 through the connecting rod 5, which will not only not affect the movement of the guide plate 1, but also will not affect the load-bearing capacity of the guide plate 1, and well solves the problems of the load-bearing capacity and the stranding area of ​​the guide plate 1 in the prior art.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
