Description

Technical Field

[0001] The utility model relates to the technical field of oil and gas drilling equipment, in particular to a turntable with a rotating drum and a remote-controlled pressure-operating system. Background Art

[0002] The lifting and pressing system is the main actuator of the pressure working machine, which mainly includes slips, lifting cylinders, turntables, etc. The slips hold the pipe string, and the pipe string is lifted and lowered by the cylinder to prevent the pipe string from falling into the well or flying out of the wellhead. The turntable is mainly used to drive the pipe string to rotate during the drilling and grinding operation. It can rotate in the light pipe string or heavy pipe string mode. At the same time, the turntable can cooperate with the top drive or power swivel for drilling and grinding construction.

[0003] The Chinese utility model patent with publication number CN210424105U discloses a dynamic sealing rotary drum, but the rotary drum and the turntable need to be combined and connected separately when in use. In actual use, it is often necessary to install a slip on the upper and lower sides of the turntable. The separate arrangement of the rotary drum and the turntable results in that a single rotary drum can only meet the requirement that the slips on one side of the turntable do not dismantle the pipelines, while the hydraulic pipelines of the slips on the other side of the turntable still need to be dismantled, which is cumbersome to operate and affects work efficiency. Utility Model Content

[0004] The utility model aims to overcome the disadvantage that the rotating drum and the turntable are separately arranged, resulting in a single rotating drum only being able to meet the requirement that the pipelines of the slips on one side of the turntable are not disassembled, while the hydraulic pipelines of the slips on the other side of the turntable still need to be disassembled, which is cumbersome to operate and affects work efficiency. A turntable with a rotating drum and a remotely controlled pressure operation system are provided.

[0005] In a first aspect, the utility model provides a turntable with a rotating drum, comprising a turntable and a rotating drum; the turntable comprises a floating crossbeam, a first gear and a driving device, the floating crossbeam is provided with a first through hole; the rotating drum comprises a fixed drum and an inner drum located inside the fixed drum and capable of rotating relative to the fixed drum; the rotating drum also comprises an annular oil passage and a first oil passage and a second oil passage connected to the annular oil passage; the annular oil passage is located between the fixed drum and the inner drum, the first oil passage is arranged in the inner drum, and the second oil passage is arranged in the fixed drum; the inner drum is fixedly connected to an end face of the first gear through the first through hole, and an end face of the first gear facing away from the inner drum is used to connect a first slip; the fixed drum is fixedly connected to the floating crossbeam; the driving device is used to drive the first gear to rotate, and an end face of the inner drum facing away from the turntable is used to connect a second slip; the first oil passage is connected to the hydraulic cylinder of the first slip through a pipeline; the first oil passage is connected to the hydraulic cylinder of the second slip through a pipeline; the second oil passage is connected to the oil tank through a pipeline.

[0006] The turntable with a rotating drum provided by the utility model adopts an integrated design concept, and the rotating drum and the turntable are connected in advance. The inner rotating drum passes through the first through hole, which can further reduce the overall height of the rotating drum and the turntable, and avoid the excessive height after the two are connected, which causes the overall height of the pressure working machine to increase; because an annular oil channel is provided between the inner rotating drum and the fixed drum, the annular oil channel can always maintain communication with the first oil channel and the second oil channel during the rotation of the inner rotating drum with the turntable, the first oil channel is connected with the hydraulic cylinders of the first cava and the second cava, and the hydraulic cylinder itself will also rotate with the turntable, so the rotation of the inner rotating drum will not affect the pipeline connected to the hydraulic cylinder; the second oil channel is provided on the outer drum, and the second oil channel is connected to the oil tank through a pipeline. Since the fixed drum does not rotate, the rotation of the rotating drum will not affect the pipeline connected to the oil tank. When in use, the first cava can be fixedly connected to the first gear, and the second cava can be fixedly installed on the inner rotating drum. The first cava and the second cava are both connected to the first oil channel. During the rotation process, the relative rotation of the inner rotating drum and the fixed drum will not affect the pipeline connection with the hydraulic cylinder and the oil tank, thereby realizing the double-sided cava without disassembling the hydraulic pipeline, and overcoming the problem that the rotating drum and the turntable are set separately, resulting in a single rotating drum only being able to meet the needs of not disassembling the pipeline of the cava on one side of the turntable, and the hydraulic pipeline of the cava on the other side of the turntable still needs to be disassembled, which is cumbersome to operate and affects work efficiency.

[0007] Preferably, a top cover and a pressure cover (222) are respectively provided at both ends of the inner drum, and the top cover is provided with a first drainage oil passage connected to the first oil passage; the pressure cover (222) is provided with a second drainage oil passage connected to the first oil passage; the top cover is fixedly connected to an end face of the first gear, and the pressure cover (222) is used to be fixedly connected to the second cava; the first drainage oil passage is connected to the hydraulic cylinder of the first cava through a pipeline, and the second drainage oil passage is connected to the hydraulic cylinder of the second cava through a pipeline.

[0008] With this structural setting, the drainage oil channels are respectively arranged on the top cover and the pressure cover of the inner drum, realizing a quick connection with the slip hydraulic cylinders on both sides, greatly simplifying the oil circuit layout, reducing unnecessary pipeline detours, and improving the hydraulic transmission efficiency.

[0009] Preferably, the first oil channel is connected with the first drainage oil channel to form an A oil channel, and the number and position of the A oil channel correspond one-to-one with the number and position of the annular oil channel; the first oil channel is connected with the second drainage oil channel to form a B oil channel, and the number and position of the B oil channel correspond one-to-one with the number and position of the annular oil channel.

[0010] With this structural arrangement, a plurality of annular oil passages can be specifically arranged along the length direction of the fixed cylinder, and there are also a plurality of corresponding A oil passages and B oil passages. Since the arrangement of the hydraulic pipeline matches the corresponding hydraulic cylinder of the driving cava, this arrangement can better cooperate with the installation of the hydraulic pipeline, so that the number of A and B oil passages matches the number of hydraulic cylinders, and each oil passage can be connected to the corresponding hydraulic cylinder through the pipeline.

[0011] Preferably, the driving device comprises a hydraulic motor and a second gear, the second gear is meshed with the first gear, and the output shaft of the hydraulic motor drives the second gear to rotate, thereby driving the first gear to rotate.

[0012] With this structural arrangement, the hydraulic motor generally has a large torque output capacity and can effectively drive the first and second gear systems meshing therewith, ensuring that the inner drum can be driven to rotate smoothly and reliably even under a heavy string load.

[0013] Preferably, there are at least four driving devices, and the driving devices are evenly distributed along the circumference of the first gear.

[0014] By adopting this structural setting, multiple drive devices are evenly distributed around the circumference of the first gear, so that the driving force can act more evenly on the inner drum, avoiding distortion caused by excessive torque load at a certain point; by adopting multiple parallel drive devices, if one of them fails, the remaining drive devices can continue to work, thus improving the fault tolerance and reliability of the overall system and avoiding paralysis of the entire rotating system due to a single point failure; by increasing the number of drive devices, the overall power output capacity can be correspondingly improved to meet the demand for providing greater torque to the inner drum, such as when drilling encounters obstacles or other special working conditions.

[0015] Preferably, the movable crossbeam is provided with a locking device, the locking device comprises a mounting seat and a locking tooth detachably connected to the mounting seat, the locking tooth is engaged with the first gear, and the mounting seat is fixedly connected to the movable crossbeam.

[0016] With this structural setting, when the position of the first gear needs to be fixed, the entire rotating system can be firmly locked to prevent it from continuing to rotate by simply engaging the locking tooth with the first gear. This mechanical locking method has a strong locking force and high reliability.

[0017] Preferably, the mounting seat comprises two mounting ears arranged opposite to each other, the locking tooth is located between the mounting ears, and the locking tooth is connected to the mounting ears via a latch.

[0018] With this structural setting, the locking tooth can be quickly disassembled by using a latch connection method. The locking tooth can be removed by simply pulling out the latch, without the need for cumbersome steps such as screwing the bolt, which greatly improves the efficiency of disassembly and assembly. The locking tooth is clamped by two mounting ears, and the connection is more secure, avoiding the risk of shaking and displacement during locking, and ensuring the stability and reliability of the locked state.

[0019] Preferably, the first slip is a load-bearing slip, and the second slip is an anti-top slip.

[0020] Preferably, the movable crossbeam is provided with a protective cover, and the protective cover is provided on the first gear.

[0021] In the second aspect, the utility model provides a remote-controlled pressure-operating system, comprising a power catwalk, a pipe lifting device, a tabletop manipulator, and a pressure-operating machine; the power catwalk is arranged on one side of the pressure-operating machine; the pipe lifting device is connected to the pressure-operating machine, and the pipe lifting device is used to pick up and deliver pipe strings between the power catwalk and the pressure-operating machine; the tabletop manipulator is installed on the pressure-operating machine, and the tabletop manipulator is used to switch the pipe string between a vertical state and an inclined state; the pressure-operating machine is used to disassemble or install the pipe string in the wellbore under the pressure state; and it also includes the above-mentioned turntable with a rotating drum, and the turntable with a rotating drum is installed on the pressure-operating machine.

[0022] The utility model provides a remote-controlled pressure-operating system, which uses a turntable with a rotating drum, and connects the rotating drum and the turntable as a whole in advance. During the rotation process, the relative rotation of the inner rotating drum and the fixed drum will not affect the pipeline connection with the hydraulic cylinder and the oil tank, and the double-sided slips do not need to be disassembled for the hydraulic pipeline, which overcomes the problem that the rotating drum and the turntable are separately arranged, resulting in a single rotating drum only being able to meet the needs of the slips on one side of the turntable without disassembling the pipeline, while the hydraulic pipeline of the slips on the other side of the turntable still needs to be disassembled, which is cumbersome to operate and affects work efficiency.

[0023] Compared with the prior art, the utility model has the following beneficial effects:

[0024] 1. The turntable with the rotating drum provided by the utility model adopts an integrated design concept, and the rotating drum and the turntable are connected together in advance. The inner rotating drum passes through the first through hole, which can further reduce the overall height of the rotating drum and the turntable, and avoid the height of the two being too high after being connected, resulting in an increase in the overall height of the pressure working machine;

[0025] 2. The turntable with a rotating drum provided by the utility model has an annular oil passage between the inner drum and the fixed drum, so that the annular oil passage can always maintain communication with the first oil passage and the second oil passage during the process of the inner drum rotating with the turntable. The first oil passage is communicated with the hydraulic cylinders of the first slip and the second slip, and the hydraulic cylinder itself can also rotate with the turntable, so the rotation of the inner drum will not affect the pipeline connected with the hydraulic cylinder; the second oil passage is arranged on the outer drum, and the second oil passage is communicated with the oil tank through the pipeline. Since the fixed drum does not rotate, the rotation of the rotating drum will not affect the pipeline connected with the oil tank;

[0026] 3. The turntable with a rotating drum provided by the utility model, when in use, the first cava can be fixedly connected to the first gear, and the second cava can be fixedly installed on the inner rotating drum, the first cava and the second cava are both connected to the first oil channel, and during the rotation process, the relative rotation of the inner rotating drum and the fixed drum will not affect the pipeline connection with the hydraulic cylinder and the oil tank, thereby realizing the double-sided cava without disassembling the hydraulic pipeline, and overcoming the problem that the rotating drum and the turntable are separately arranged, resulting in a single rotating drum only being able to meet the requirement of not disassembling the pipeline of the cava on one side of the turntable, while the hydraulic pipeline of the cava on the other side of the turntable still needs to be disassembled, which is cumbersome to operate and affects work efficiency.

[0027] 4. The remote-controlled pressure-operating system provided by the utility model uses a turntable with a rotating drum, and the rotating drum and the turntable are connected together in advance. During the rotation process, the relative rotation of the inner rotating drum and the fixed drum will not affect the pipeline connection with the hydraulic cylinder and the oil tank, and the double-sided cava does not need to disassemble the hydraulic pipeline. This overcomes the problem that the rotating drum and the turntable are set separately, resulting in a single rotating drum only being able to meet the needs of the cava on one side of the turntable without disassembling the pipeline, while the hydraulic pipeline of the cava on the other side of the turntable still needs to be disassembled, which is cumbersome to operate and affects work efficiency.

[0043] Example 1

[0044] like Figure 1-Figure 7 As shown, a turntable with a rotating drum comprises a turntable 1 and a rotating drum 2; the turntable 1 comprises a traveling beam 11, a first gear 12 and a driving device 13, and the traveling beam 11 is provided with a first through hole 111;

[0045] The rotating drum 2 includes a fixed drum 21 and an inner drum 22 located inside the fixed drum 21 and capable of rotating relative to the fixed drum 21. Specifically, for example, a bearing may be provided between the fixed drum 21 and the inner drum 22.

[0046] The rotating cylinder 2 also includes an annular oil passage 23 and a first oil passage 24 and a second oil passage 25 connected to the annular oil passage 23; the annular oil passage 23 is located between the fixed cylinder 21 and the inner rotating cylinder 22, the first oil passage 24 is provided in the inner rotating cylinder 22, and the second oil passage 25 is provided in the fixed cylinder 21; the fixed cylinder 21 and the inner rotating cylinder 22 are directly provided with a sealing assembly for sealing the annular oil passage 23. The annular oil passage 23 is specifically formed as follows: an annular oil groove is provided on the inner wall of the fixed cylinder 21, and the annular oil groove cooperates with the inner rotating cylinder 22 to form the annular oil passage 23. The sealing assembly for sealing the annular oil passage 23 can specifically be a sealing rubber ring, and sealing rubber rings can be provided on both the upper and lower sides of the annular oil passage 23 to prevent leakage of hydraulic oil in the annular oil passage 23.

[0047] The inner drum 22 passes through the first through hole 111 and is fixedly connected to one end surface of the first gear 12. Figure 2As shown, the outer surface of the fixed cylinder 21 is provided with a flange fixedly connected to the fixed cylinder 21, and the fixed cylinder 21 is fixedly connected to the floating crossbeam 11 through the flange. The floating crossbeam 11 is equipped with a protective cover 14, and the protective cover 14 is provided on the first gear 12. The middle part of the protective cover 14 is provided with a through hole for the first gear 12 to pass through. Figure 2 The inner drum 22 is fixedly connected to the lower end face of the first gear 12. The end face of the first gear 12 facing away from the inner drum 22 is used to connect the first slip. Figure 2 The upper end surface of the first gear 12 is provided with a screw hole for connecting the first slip, and the first slip is fixedly connected to the upper end surface of the first gear 12 by bolts. The protective cover 14 can ensure the safety of the operator and prevent the gear from being corroded by rain and dust.

[0048] like Figure 4 As shown, the driving device 13 is used to drive the first gear 12 to rotate, and the driving device 13 may include a hydraulic motor 131 and a second gear 132. The second gear 132 is meshed with the first gear 12. The output shaft of the hydraulic motor 131 drives the second gear 132 to rotate, thereby driving the first gear 12 to rotate. Further, there are at least four driving devices 13, and the driving devices 13 are evenly distributed along the circumference of the first gear 12.

[0049] The end surface of the inner drum 22 facing away from the turntable 1 is used to connect with the second slip. For example, the end surface of the inner drum 22 facing away from the turntable 1 may be provided with a screw hole for connecting with the second slip, and the second slip is fixedly connected to the inner drum 22 by bolts.

[0050] The first oil passage 24 is connected to the hydraulic cylinder of the first slip through a pipeline; the first oil passage 24 is connected to the hydraulic cylinder of the second slip through a pipeline; the second oil passage 25 is connected to the hydraulic oil tank through a pipeline.

[0051] Further, such as Figure 6 , Figure 7As shown, the two ends of the inner drum 22 are respectively provided with a top cover 221 and a pressure cover 222, the top cover 221 is provided with a first drainage oil passage 26 connected to the first oil passage 24, and the outer port of the first drainage oil passage 26 can be installed with a straight-through oil cup connected to a pipeline; the pressure cover 222 is provided with a second drainage oil passage 27 connected to the first oil passage 24, and the outer port of the second drainage oil passage 27 can be installed with a straight-through oil cup connected to a pipeline; the top cover 221 is fixedly connected to one end surface of the first gear 12, and the pressure cover 222 is used to be fixedly connected to the second slip; specifically, the first slip can be a load-bearing slip, and the second slip can be an anti-top slip. The first drainage oil passage 26 is connected to the hydraulic cylinder of the first slip through a pipeline, and the second drainage oil passage 27 is connected to the hydraulic cylinder of the second slip through a pipeline. The drainage oil passages are respectively arranged on the top cover 221 and the gland of the inner drum 22, so as to realize quick connection with the slip hydraulic cylinders on both sides, greatly simplify the oil circuit layout, reduce unnecessary pipeline detours, and improve the hydraulic transmission efficiency.

[0052] Further, such as Figure 7 As shown, the first oil passage 24 is connected with the first drainage oil passage 26 to form an A oil passage, and the number and position of the A oil passage correspond to the number and position of the annular oil passage 23; the first oil passage 24 is connected with the second drainage oil passage 27 to form a B oil passage, and the number and position of the B oil passage correspond to the number and position of the annular oil passage 23. With this structural arrangement, a plurality of annular oil passages 23 can be provided along the length direction of the fixed cylinder 21, for example Figure 6 , Figure 7 The case where four annular oil passages 23 are provided is shown. There are also multiple corresponding A oil passages and B oil passages, for example, four are also provided respectively. Since the setting of the hydraulic pipeline matches the corresponding hydraulic cylinder driving the slips, such a setting can better cooperate with the installation of the hydraulic pipeline, so that the number of A oil passages and B oil passages matches the number of hydraulic cylinders, and each oil passage can be connected to the corresponding hydraulic cylinder through the pipeline.

[0053] The turntable with a rotating drum provided in this embodiment adopts an integrated design concept, and the rotating drum 2 and the turntable 1 are connected in advance. The inner rotating drum 22 passes through the first through hole 111, which can further reduce the overall height of the rotating drum 2 and the turntable 1, and avoid the height being too high after the two are connected, resulting in an increase in the overall height of the pressure working machine; since an annular oil passage 23 is provided between the inner rotating drum 22 and the fixed drum 21, the annular oil passage 23 can always maintain communication with the first oil passage 24 and the second oil passage 25 during the rotation of the inner rotating drum 22 with the turntable 1. The first oil passage 24 is connected to the hydraulic cylinders of the first cava and the second cava, and the hydraulic cylinder itself will also rotate with the turntable 1, so the rotation of the inner rotating drum 22 will not affect the pipeline connected to the hydraulic cylinder; the second oil passage 25 is provided on the outer drum, and the second oil passage 25 is connected to the oil tank through a pipeline. Since the fixed drum 21 does not rotate, the rotation of the rotating drum 2 will not affect the pipeline connected to the oil tank.

[0054] When in use, the first cava can be fixedly connected to the first gear 12, and the second cava can be fixedly installed on the inner rotating drum 22. The first cava and the second cava are both connected to the first oil channel 24. During the rotation process, the relative rotation of the inner rotating drum 22 and the fixed drum 21 will not affect the pipeline connection with the hydraulic cylinder and the oil tank, thereby realizing the double-sided cava without disassembling the hydraulic pipeline, and overcoming the problem that the rotating drum 2 and the turntable 1 are separately arranged, resulting in a single rotating drum 2 that can only meet the needs of not disassembling the pipeline of the cava on one side of the turntable 1, and the hydraulic pipeline of the cava on the other side of the turntable 1 still needs to be disassembled, which is cumbersome to operate and affects work efficiency.

[0055] Example 2

[0056] On the basis of Example 1, Figure 1 , Figure 5 As shown, the upper surface of the traveling cross beam 11 is fixedly mounted with a locking device 3. The locking device comprises a mounting seat 31 and a locking tooth 32 detachably connected to the mounting seat 31, the locking tooth 32 is engaged with the first gear 12, and the mounting seat 31 is fixedly connected to the traveling cross beam 11, for example, by bolts.

[0057] Further, the mounting seat 31 includes two mounting ears 311 arranged opposite to each other, the locking tooth 32 is located between the two mounting ears 311, the mounting ears 311 can be a hollow plate-like structure, the latch 33 can pass through the mounting ears 311, and the locking tooth 32 is connected to the mounting ears 311 through the latch 33. Specifically, for example Figure 5 As shown, two latches 33 pass through the mounting ears 311 and are inserted into the handle of the locking tooth 32, and the tooth portion of the locking tooth 32 is meshed with the first gear 12. When unlocking is required, only the latch 33 needs to be pulled out to quickly separate the locking tooth 32 from the first gear 12.

[0058] With this structural setting, when the position of the first gear 12 needs to be fixed, the locking tooth 32 only needs to be meshed with the first gear 12 to firmly lock the entire rotating system and prevent it from continuing to rotate. This mechanical locking method has a strong locking force and high reliability. With the latch 33 connection method, the locking tooth 32 can be quickly disassembled and assembled. The locking tooth 32 can be removed by simply pulling out the latch 33 without the need for cumbersome steps such as screwing the bolt, which greatly improves the efficiency of disassembly and assembly. The locking tooth 32 is clamped by two mounting ears 311, and the connection is more secure, avoiding the risk of shaking and displacement during locking, and ensuring the stability and reliability of the locked state.

The pressure-operating system also includes a turntable with a rotating drum provided in Example 2, and the turntable with a rotating drum is installed on the pressure-operating machine.

[0061] The remote-controlled pressure-operating system provided by the utility model uses a turntable with a rotating drum, and the rotating drum 2 is connected with the turntable 1 in advance. During the rotation process, the relative rotation of the inner rotating drum 22 and the fixed drum 21 will not affect the pipeline connection with the hydraulic cylinder and the oil tank, so that the hydraulic pipelines of the double-sided slips do not need to be disassembled, and the problem that the rotating drum 2 and the turntable 1 are separately arranged, resulting in a single rotating drum 2 that can only meet the needs of not disassembling the pipelines of the slips on one side of the turntable 1, and the hydraulic pipelines of the slips on the other side of the turntable 1 still need to be disassembled, which is cumbersome to operate and affects work efficiency.
