Description

Technical Field

[0001] The invention relates to the technical field of catwalks, and in particular to a catwalk mechanism and an automatic drilling tool raising system having the same. Background Art

[0002] In the process of engineering drilling and well drilling, a large number of drilling tools such as casing and drill rods are required. In order to realize the round-trip transportation of drilling tools between the ground and the drilling platform, the traditional method of transporting drilling tools is usually to complete the process of drilling tools on and off the drilling platform through pneumatic winch lifting, manual pushing and pulling, and catwalk mechanism. When transporting large-sized casing, a crane is even required to assist the operation. At the same time, it is necessary to manually align the drilling tools with the main engine of the drilling platform, and the process is complicated. In the traditional transportation plan, faced with the task of transporting a large number of casing and drill rods, the existing catwalk mechanism is often set up for the drill rods in the drilling tools, and it is impossible to take into account the reasonable transportation of multiple drilling tools. This work not only has many procedures, but also has a high risk factor, which may pose a threat to the personal safety of the staff. Summary of the invention

[0004] In a first aspect, a catwalk mechanism is proposed, comprising: a base, a catwalk body, a lifting device, a conveying device, a clamping and transferring device, and a pushing mechanism.

[0005] The conveying device is rotatably arranged on the base, and is used to convey the drilling tool group to the catwalk body; the drilling tool group includes a casing and a drill rod arranged inside the casing;

[0006] The catwalk body includes a base frame and a sliding plate, the end of the base frame is rotatably arranged on the base, the sliding plate is slidably arranged on the base frame, and the sliding plate is used to receive and push the drilling tool group transmitted from the transmission device;

[0007] The pushing mechanism is arranged on the sliding plate and is used for docking the drill tool group to push out the drill rod in the casing; one end of the lifting device is connected to the base frame and the other end is connected to the base, and is used for lifting the free end of the base frame from a preset flat state to a preset lifting state;

[0008] The clamping and transferring device is arranged at the free end of the base frame and corresponds to the sliding plate, and is used to clamp and transfer the drill rod and / or casing on the sliding plate along the extension direction of the sliding plate. In practical applications, the clamping and transferring device includes a vise structure, which can effectively clamp the pushing mechanism and the drill rod or casing of the drilling tool group pushed by the sliding plate to transfer the drill rod or casing of the drilling tool group to the power head.

[0009] In some specific embodiments, a pipe rack for placing a drilling tool group is further included, and the pipe rack is arranged on a side edge of the base close to the conveying device; the conveying device is used to abut against the pipe rack to obtain the drilling tool group when flipped to a first preset position, and flip to a second preset position when the base frame is in a preset flat state, so as to transport the drilling tool group to the sliding plate of the catwalk body.

[0010] In some specific embodiments, the pushing mechanism includes a movable lifting portion, which is used to move along the extension direction of the base frame to lift the drill rod in the casing so that the drill rod is exposed from the casing;

[0011] A lifting platform is provided at one end of the lifting part close to the free end of the base frame, and the outer diameter of the lifting platform is not larger than the inner diameter of the casing and not smaller than the outer diameter of the drill pipe; or a lifting groove is provided at one end of the lifting part close to the drill bit group, and the outer diameter of the lifting groove is not larger than the inner diameter of the casing, and the inner diameter of the lifting groove is not smaller than the outer diameter of the drill pipe.

[0012] In some specific embodiments, the conveying device includes a fixed portion, a movable portion and a limit rod, the fixed portion is disposed on the base, and the movable portion is rotatably disposed on the fixed portion;

[0013] One end of the limit rod is movably connected to the fixed part, and the other end of the limit rod is provided with a sliding limit groove, the sliding limit groove is provided with a first end point near the connection between the limit rod and the fixed part, and the sliding limit groove is provided with a second end point away from the connection between the limit rod and the fixed part;

[0014] A slider is protruding from the movable part, and the slider is slidably arranged in the sliding limit groove. The movable part is used to flip to a first preset position when the slider is located at the first end point, and flip to a second preset position when the slider is located at the second end point.

[0015] In some specific embodiments, a bending portion extends from the free end of the movable portion, and a first preset angle is formed between the bending portion and the movable portion, and the first preset angle is between 100° and 150°; the bending portion is used to abut against the pipe rack when the movable portion is flipped to the first preset position to receive the drill tool group on the pipe rack; one side of the fixed portion abuts against the base frame in a preset flat state, and the other side of the fixed portion is rotatably connected to the movable portion, and the movable portion is used to drive the drill tool group to slide when flipped to the second preset position, and abut against the base frame through the fixed portion to allow the drill tool group to enter the sliding plate.

[0016] In practical applications, the transition between the bent portion and the movable portion can be set to an arc structure, so that after the bent portion abuts against the pipe rack to obtain the drill tool group, the drill tool group can contact the movable part through the arc structure during the process of rolling along the bent portion to the abutment position between the movable part and the base frame, thereby reducing the friction between the drill tool group and the movable part during the rolling process and preventing the drill tool group from being worn.

[0017] In some specific embodiments, one or more sets of support mechanisms are provided on both sides of the base;

[0018] The supporting mechanism includes a transverse connecting member and a hydraulic supporting leg; one end of the transverse connecting member is rotatably connected to the side edge of the base, and the other end is connected to the hydraulic supporting leg;

[0019] The hydraulic legs are used to extend and retract to drive the entire base to rise or fall.

[0020] In some specific embodiments, the sliding plate is provided with a receiving groove, which extends along the length direction of the sliding plate and is used to accommodate the drilling tool group; the groove wall of the receiving groove can present a V-shaped structure to provide support for the drilling tool group, and the groove wall of the receiving groove forms a second preset angle with the plane where the base frame is located, which is used to limit the drilling tool group.

[0021] In some specific embodiments, an adjustment mechanism is further included. The adjustment mechanism is rotatably disposed on the groove wall of the accommodating groove and is used to swing relative to the groove wall of the accommodating groove to push the drilling tool group in the accommodating groove out of the sliding plate.

[0022] In some specific embodiments, a limit block is further provided on the base frame on a side of the accommodating groove away from the drilling tool group, and a side wall of the limit block facing the accommodating groove forms a third preset angle with the plane where the base frame is located; the angle of the third preset angle is greater than the second preset angle.

[0023] In actual applications, during the overall operation of the catwalk mechanism, due to inertia, when the conveying device conveys the drill tool group to the receiving slot on the base frame, if the depth of the receiving slot is insufficient and the movement speed of the drill tool group is too fast, the drill tool group may move to an area that exceeds the receiving slot. At this time, the drill tool group can be limited and blocked by setting a limit block.

[0024] Furthermore, by making the third preset angle formed by the groove wall on one side of the accommodating groove and the plane where the base frame is located greater than the second preset angle, the groove wall on one side of the sliding plate can be extended to a certain extent, providing support force for the drill tool group and resistance to its movement, so as to achieve stable limitation of the drill tool group in the accommodating groove and prevent the drill tool group from rolling out from the groove wall on the other side of the accommodating groove.

[0025] In a second aspect, an automatic drilling tool raising system is proposed, comprising any catwalk mechanism in the aforementioned technical solutions, and also comprising a drilling tower and a power head, wherein the power head is movably arranged on the drilling tower;

[0026] The clamping and conveying device is used to clamp the drill rod and the casing on the sliding plate in sequence, and convey the drill rod and the casing in sequence along the extending direction of the sliding plate;

[0027] The power head is used to move to an area close to the clamping and conveying device and tilt up after the clamping and conveying device delivers the drill rod, so as to connect the drill rod and the casing in sequence.

[0028] In some specific embodiments, it further includes a first monitoring device, a second monitoring device and a control device; the clamping and transferring device, the sliding plate and the pushing mechanism are respectively connected to a driving device;

[0029] The first monitoring device is disposed on the sliding plate and is used to detect whether there is a drilling tool group on the sliding plate.

[0030] The control device is electrically connected to the first monitoring device, the second monitoring device, the pushing mechanism, the conveying device and the driving device respectively, and is used to control the driving device to drive the pushing mechanism to move when there is a drill tool group on the sliding plate, and to control the driving device to drive the conveying device to obtain the drill tool group when there is no drill tool group on the sliding plate;

[0031] The second monitoring device is arranged on the clamping and transferring device, and is used to detect whether there is a drill rod or a casing in the clamping and transferring device, and whether the drill rod or the casing has moved to the preset docking area. The control device is also electrically connected to the power head, and is used to control the power head to dock with the casing or the drill rod of the drilling tool group when the drill rod or the casing moves to the preset docking area.

[0032] In practical applications, the clamping and transferring device includes a vise structure and a cylinder structure, and the vise structure is connected to the cylinder mechanism, the driving device and the control device respectively. The vise structure can clamp the push mechanism and the drill rod or casing of the drill tool group pushed by the sliding plate. The second monitoring device is used to detect whether there is a drill rod or casing in the vise structure, and further detect whether the clamping of the drill rod or casing is completed. In a specific application process, the receiving groove in the sliding plate accommodates the drill tool group and drives the drill tool group to move along the length direction of the sliding plate. The pushing mechanism on the sliding plate further enters the casing in the drill tool group to push the drill rod in the drill tool group out of the casing. When the front end of the drill rod enters the position corresponding to the vise structure, the vise structure clamps the drill rod under the drive of the driving device. At this time, the cylinder mechanism pushes the vise structure to clamp the drill rod and deliver it forward along the length direction of the sliding plate. After moving a preset distance, the vise structure returns to its original position and re-clamps the next section of the drill rod. The aforementioned process of delivering the drill rod is repeated to realize the process of clamping and delivering the drill rod and docking with the power head. After the drill rod is docked, the casing is docked.

[0033] In practical applications, the preset docking area may refer to a position corresponding to a specific length by which the casing head of the drill string needs to extend relative to the clamping and transferring device, or may refer to a position corresponding to a length by which the drill rod in the drill string needs to extend further relative to the casing. The second monitoring device may detect whether there is a casing or a drill rod of the corresponding drill rod group in the preset docking area by means of sensor detection or the like.

[0034] In a specific embodiment, the user can adjust the moving distance of the pushing mechanism on the chassis and / or the moving distance of the sliding plate according to actual needs, position data of the preset docking area, relative position between the catwalk mechanism and the drilling tower and the power head, distance data, etc.

[0035] Beneficial effects: This application proposes a catwalk mechanism and an automatic drilling tool system having the same. By setting a base, a catwalk body, a lifting device, a conveying device and a pipe rack, and making each component cooperate with each other, it is possible to realize the automatic conveying of the drilling tool group, the respective docking of the drill rod and casing in the drilling tool group with the power head, and the position conveying. Furthermore, the overall process of drilling tool installation is made intelligent and automated through the automatic drilling tool system. Compared with the traditional working method, the drill rod and casing in the drilling tool group can be processed in a targeted manner in sequence, which reduces the manpower input in the project, reduces the manual operation steps, and effectively improves the efficiency and safety of drilling construction.

The conveying device 4 is rotatably arranged on the base 1, and the pipe rack 5 is arranged on a side edge of the base 1 close to the conveying device 4, such as Figure 3 As shown in the top view.

[0057] In some specific embodiments, the pushing mechanism 22 includes a movable lifting portion 221, and the lifting portion 221 is used to move along the extension direction of the base frame 21 to lift the drill rod 92 in the casing 91 so that the drill rod 92 is exposed from the casing 91;

[0059] In some specific embodiments, the conveying device 4 includes a fixed portion 41, a movable portion 42 and a limiting rod 43, the fixed portion 41 is disposed on the base 1, and the movable portion 42 is rotatably disposed on the fixed portion 41;

[0060] One end of the limiting rod 43 is movably connected to the fixing part 41, and the other end of the limiting rod 43 is provided with a sliding limiting groove 431, and the sliding limiting groove 431 is provided with a first end point 432 near the connection between the limiting rod 43 and the fixing part 41, and the sliding limiting groove 431 is provided with a second end point 433 away from the connection between the limiting rod 43 and the fixing part 41;

[0061] A slider 421 is protruding from the movable portion 42 , and the slider 421 is slidably disposed in the sliding limit groove 431 . The movable portion 42 is used to flip to a first preset position when the slider 421 is located at the first end point 432 , and flip to a second preset position when the slider 421 is located at the second end point 433 .

[0062] In some specific embodiments, a bent portion 422 extends from the free end 211 of the movable portion 42, and a first preset angle is formed between the bent portion 422 and the movable portion 42, and the first preset angle is between 100° and 150°. Figure 6 As shown in the middle angle α; the bending portion 422 is used to abut against the pipe rack 5 when the movable portion 42 is flipped to the first preset position to receive the drill group 9 on the pipe rack 5; one side of the fixed portion 41 abuts against the base frame 21 in a preset flat state, and the other side of the fixed portion 41 is rotatably connected to the movable portion 42, and the movable portion 42 is used to drive the drill group 9 to slide when flipped to the second preset position, and abuts against the base frame 21 through the fixed portion 41 to allow the drill group 9 to enter the sliding plate 23.

[0063] In actual applications, the transition between the bent portion 422 and the movable portion 42 can be set to an arc structure, so that after the bent portion 422 abuts against the pipe rack 5 to obtain the drill bit 9, the drill bit 9 can roll along the bent portion 422 to the abutment position between the movable portion 42 and the base frame 21. The arc structure can achieve contact with the movable portion 42, thereby reducing the friction between the drill bit 9 and the movable portion 42 during rolling and preventing the drill bit 9 from being worn.

[0064] In some specific embodiments, the lifting device 3 includes a lifting rod group 31 and an auxiliary rod group 32, wherein the lifting rod group 31 includes a folding portion; a first connection point 331 close to the free end 211 of the base frame 21 and a second connection point 332 away from the free end 211 of the base frame 21 are provided on the base 1; and a third connection point 333 is provided on the side of the base frame 21 facing the base 1. One end of the lifting rod group 31 is connected to the first connection point 331 on the base 1, and the other end is connected to the third connection point 333 on the base frame 21; one end of the auxiliary rod group 32 is connected to the second connection point 332 on the base 1, and the other end is connected to the third connection point 333 on the base frame 21. By providing the lifting rod group 31 and the auxiliary rod group 32, multiple support points can be provided for the base frame 21, so that the auxiliary rod group 32 can share the pressure of lifting the base frame 21, so that the lifting device 3 can lift the base frame 21 faster.

[0065] In some specific embodiments, one or more supporting mechanisms 7 are provided on both sides of the base 1. The supporting mechanism 7 includes a transverse connecting member and a hydraulic support leg; one end of the transverse connecting member is rotatably connected to the side edge of the base 1, and the other end is connected to the hydraulic support leg; the hydraulic support leg is used to extend and retract to adjust to drive the base 1 to be lifted or lowered as a whole. In practical applications, the hydraulic support leg includes a long-stroke telescopic hydraulic support leg, which can lift the base 1 as a whole to a higher height, so as to lift the base frame 21 of the catwalk mechanism and the components located on the base frame 21 together, which can better adapt to the height of the power head 931 that needs to be docked with the catwalk mechanism at different heights, and can also better place the catwalk mechanism on an external transport device to transport the catwalk mechanism.

[0066] In some specific embodiments, the sliding plate 23 has a receiving groove 231, which extends along the length direction of the sliding plate 23 and is used to receive the drilling tool group 9; in practical applications, the groove wall 232 of the receiving groove 231 may present a V-shaped structure, so that the receiving groove 231 is a V-shaped groove, and the groove wall 232 of the receiving groove 231 forms a second preset angle with the plane where the base frame 21 is located, which is used to limit the drilling tool group 9.

[0068] In some specific embodiments, a limit block 233 is further provided on the base frame 21 on a side of the accommodating groove 231 away from the drilling tool group 9, and a side wall of the limit block 233 facing the accommodating groove 231 forms a third preset angle with the plane where the base frame 21 is located; the angle of the third preset angle is greater than the second preset angle.

[0069] In actual applications, during the overall operation of the catwalk mechanism, due to inertia, when the conveying device 4 conveys the drill tool group 9 to the receiving groove 231 on the base frame 21, if the depth of the receiving groove 231 is insufficient and the movement speed of the drill tool group 9 is too fast, the drill tool group 9 may move to an area beyond the receiving groove 231. At this time, the drill tool group 9 can be limited and blocked by setting a limit block 233.

[0070] Further, such as Figure 7 The sectional view of the receiving groove 231 and the limiting block 233 on the middle sliding plate 23 in the first preset direction is shown in FIG. Figure 7 As shown in the middle angle θ, the plane where the base frame 21 is located is as shown in Figure 7 As shown in the middle plane b, the first preset direction is as follows Figure 5 As shown in the direction A in the middle. By making the third preset angle formed by the side wall 232 of the limiting block 233 facing the receiving groove 231 and the plane where the bottom frame 21 is located greater than the second preset angle, the side wall 232 of the sliding plate 23 can be extended to a certain extent, providing support force for the drill group 9 and resistance to its movement, so as to achieve stable positioning of the drill group 9 in the receiving groove 231, prevent the drill group 9 from accidentally rolling out of the other side wall 232 of the receiving groove 231, and ensure the normal execution of the drilling group transportation process. In a specific embodiment, the angle θ can be 90 degrees.

[0071] In some specific embodiments, the length extension direction of the sliding plate 23 is parallel to the axial direction of the casing 91 and the drill rod 92 of the drilling tool group 9. In a specific embodiment, the pipe rack 5 includes a supporting pipe rack, wherein the extension direction of the supporting pipe rack has an intersection with the extension direction of the base frame 21 and the extension direction of the drilling tool group 9. This allows multiple drilling tool groups 9 to be arranged on the supporting pipe rack and continuously transport the drilling tool groups 9 in the direction of the conveying device 4.

[0072] In a specific embodiment, the pipe rack 5 is also connected to a power mechanism for generating a thrust on the pipe rack 5 toward the base frame 21 to push the drilling tool set 9 on the pipe rack 5 to an area on the pipe rack 5 that abuts the conveying device 4 .

[0073] This embodiment provides a catwalk mechanism, which can realize automatic transmission of the drilling tool group, and the docking and position transmission of the drill pipe and casing in the drilling tool group with the power head by setting a base, a catwalk body, a lifting device, a transmission device and a pipe rack, and making each component cooperate with each other. It greatly reduces the manpower input in the project, reduces the manual operation steps, and effectively improves the efficiency and safety of drilling construction.

[0074] Example 2

[0075] Embodiment 2 of the present application discloses an automatic drilling tool system, and the specific scheme is as follows:

[0076] An automatic drilling tool system, comprising any catwalk mechanism in the above technical solutions, such as Figure 8 As shown, it also includes a drilling tower 93 and a power head 931, and the power head 931 is movably arranged on the drilling tower 93. The clamping and transferring device 6 is used to sequentially clamp the drill rod 92 and the casing 91 on the sliding plate 23, and sequentially deliver the drill rod 92 and the casing 91 along the extending direction of the sliding plate 23;

[0077] The power head 931 is used to move to an area close to the clamping and conveying device 6 and tilt up after the clamping and conveying device 6 delivers the drill rod 92, so as to connect the drill rod 92 and the casing 91 in sequence.

[0078] After the drill rod 92 is delivered by the clamping and transferring device 6 through the power head 931, it moves on the drilling tower 93 to the area close to the clamping and transferring device 6 and tilts up to dock with the drill rod 92. After the docking with the drill rod 92 is completed, the power head 931 further docks with the casing 91. Compared with the traditional transportation method, the power head 931 can automatically identify and dock the drill rod 92 and the casing 91 in turn in a targeted manner, making the docking process more standardized, which can quickly improve the docking efficiency and reduce the input of manual operation.

[0079] In some specific embodiments, it also includes a first monitoring device 81, a second monitoring device 82 and a control device 10; the clamping and transferring device 6, the sliding plate 23 and the pushing mechanism 22 are respectively connected to the driving device 83; the first monitoring device 81 is arranged on the sliding plate 23, and is used to detect whether there is a drilling tool group 9 on the sliding plate 23.

[0080] The control device 10 is electrically connected to the first monitoring device 81, the second monitoring device 82, the pushing mechanism 22, the conveying device 4 and the driving device 83 respectively, and is used to control the driving device 83 to drive the pushing mechanism 22 to move when there is a drilling tool group 9 on the sliding plate 23, and to control the driving device 83 to drive the conveying device 4 to obtain the drilling tool group 9 when there is no drilling tool group 9 on the sliding plate 23;

[0081] The second monitoring device 82 is disposed on the clamping and transferring device 6, and is used to detect whether there is a drill rod 92 or a casing 91 in the clamping and transferring device 6, and whether the drill rod 92 or the casing 91 has moved to the preset docking area. The control device 10 is also electrically connected to the power head 931, and is used to control the power head 931 to dock with the casing 91 or the drill rod 92 of the drilling tool group 9 when the drill rod 92 or the casing 91 moves to the preset docking area.

[0082] In practical applications, the clamping and transferring device 6 includes a vise structure 61 and a cylinder structure 62, and the vise structure 61 is respectively connected to the cylinder mechanism, the driving device 83 and the control device 10. The vise structure 61 can clamp the drill rod 92 or the casing 91 of the drilling tool group 9 pushed by the pushing mechanism 22 and the sliding plate 23, and the second monitoring device 82 is used to detect whether there is a drill rod 92 or a casing 91 in the vise structure 61, and further detect whether the clamping of the drill rod 92 or the casing 91 is completed.

[0083] In a specific application process, the receiving groove 231 in the sliding plate 23 receives the drill set 9 and drives the drill set 9 to move along the length direction of the sliding plate 23. The pushing mechanism 22 on the sliding plate 23 further enters the casing 91 in the drill set 9 and pushes the drill rod 92 in the drill set 9 out of the casing 91. When the front end of the drill rod 92 enters the corresponding position of the vise structure 61, the vise structure 61 clamps the drill rod 92 under the drive of the driving device 83. At this time, the cylinder mechanism pushes the vise structure 61 to clamp the drill rod 92 and deliver it forward along the length direction of the sliding plate 23. After moving a preset distance, the vise structure 61 returns to the original position and re-clamps the next section of the drill rod 92. The aforementioned process of delivering the drill rod 92 is repeated to achieve the process of clamping and delivering the drill rod 92 and docking with the power head 931. After the drill rod 92 is docked, the casing 91 is docked.

[0084] The schematic diagram of the electrical connection between the control device 10 and other modules is as follows: Fig. 9 shown.

[0085] In practical applications, the preset docking area may refer to a position corresponding to a specific length by which the head of the casing 91 in the drill string 9 needs to extend relative to the clamping and transferring device 6, or may refer to a position corresponding to a length by which the drill rod 92 in the drill string 9 needs to further extend relative to the casing 91. The second monitoring device 82 may detect whether there is a casing 91 or a drill rod 92 of the corresponding drill rod 92 group in the preset docking area by means of sensor detection or the like.

[0086] In a specific embodiment, the user can adjust the moving distance of the pushing mechanism 22 on the base frame 21 and / or the moving distance of the sliding plate 23 according to actual needs, position data of the preset docking area, the relative position between the catwalk mechanism and the drilling tower 93, the power head 931, distance data, etc.

[0087] This embodiment provides an automatic drilling tool system, including any catwalk mechanism in the aforementioned technical solution, and by setting a first monitoring device, a second monitoring device and a control device, it is possible to realize the interactive cooperation between the base, the catwalk body, the lifting device and the conveying device, and to realize the orderly automatic conveyance of the drilling tool group, and to sequentially connect and convey the drill rod and casing in the drilling tool group to the power head, respectively. It greatly reduces the manpower input in the project, reduces the manual operation steps, and effectively improves the efficiency and safety of drilling construction.
