Description

Technical Field

[0001] The utility model relates to the technical field of petroleum drilling mechanical equipment, in particular to a drill rod supporting device. Background Art

[0002] At the oil drilling site, it is usually necessary to connect multiple drill pipes in sequence using male and female threads to achieve the ideal drilling depth. Due to the long length of the drill pipe, a power catwalk is currently used to realize the automatic transportation of the pipe string between the ground pipe arrangement area and the drilling platform. However, when transporting the drill pipe, the drill pipe is still placed horizontally for the convenience of transportation. Therefore, after the drill pipe is transported to the drilling platform, it is necessary to straighten the drill pipe before it can be lowered into the drilling well. Since there is a certain height distance between the drilling platform and the drilling well, when straightening and lowering the drilling well, if some buffering measures are not used, the lower end of the drill pipe will produce a large impact force on the wellhead direction;

[0003] Currently, there are mechanical arm devices that can buffer the impact force of lowering the drill pipe, but they mainly use a gripper to grab the drill pipe and slowly lower it vertically toward the wellhead to reduce the impact force. However, the gripper has a complex structure and is more complicated to operate. It is necessary to accurately grasp the drill pipe and lower it to the appropriate position, which affects the drilling efficiency. Utility Model Content

[0028] At the oil drilling site, it is usually formed by threading the upper drill pipe and the lower drill pipe in sequence according to the drilling depth. Due to the large diameter of the drill pipe, a power catwalk is currently used to realize the automatic transportation of the pipe string between the ground pipe arrangement area and the drilling platform. However, when transporting the drill pipe, the drill pipe is still placed horizontally for the convenience of transportation. Therefore, after the drill pipe is transported to the drilling platform, it is necessary to straighten the drill pipe before it can be lowered into the drilling well. Since there is a certain height distance between the drilling platform and the drilling well, when straightening and lowering the drilling well, if some buffering measures are not used, the lower end of the drill pipe will produce a large impact force on the wellhead direction;

[0029] Currently, there are mechanical arm devices that can buffer the impact force of lowering the drill pipe, but they mainly use a gripper to grab the drill pipe and slowly lower it vertically toward the wellhead to reduce the impact force. However, the gripper has a complex structure and is more complicated to operate. It is necessary to accurately grasp the drill pipe and lower it to the appropriate position, which affects the drilling efficiency.

[0030] In order to solve the above technical problems, the utility model provides a drill rod supporting device 100.

[0031] like Figure 1-Figure 4 As shown, in one embodiment of the utility model, the drill rod supporting device 100 includes: a base 1, a swing arm 2, a telescopic arm 3, a supporting member 5 and a first driving member 4; the two ends of the swing arm 2 extending along the first direction are respectively a hinged end 22 and a free end 21, wherein the hinged end 22 is hinged to the base 1; the telescopic arm 3 is connected to the free end 21 of the swing arm 2, and the telescopic arm 3 can be telescoped along a second direction, and the second direction is different from the first direction; the supporting member 5 is used to support the drill rod 200, and the supporting member 5 is arranged at the end of the telescopic arm 3, and the telescopic arm 3 can be telescoped along the second direction to drive the supporting member 5 to move closer to or away from the swing arm 2; the two ends of the first driving member 4 are respectively hinged to the base 1 and the swing arm 2, and the first driving member 4 is used to drive the swing arm 2 so that the free end 21 of the swing arm 2 swings around the hinged end 22.

[0032] The first direction mentioned in this embodiment is as follows Figure 1 The x direction is shown in , and the second direction is Figure 1 The y direction shown in .

[0033] It can be understood that when the drill rod supporting device 100 is in use, the base 1 is used to fix the entire device, and the position of the supporting member 5 is adjusted by the swing arm 2 and the telescopic arm 3, so that the supporting member 5 can be adjusted to a suitable position to support the drill rod 200. Specifically, when adjusting the position of the supporting member 5, the swing arm 2 is driven to rotate around the base 1 by the first driving member 4, so as to adjust the position of the free end 21 of the swing arm 2. In addition, since the telescopic arm 3 is arranged at the free end 21, when the swing arm 2 swings, the telescopic arm 3 also adjusts its position accordingly, and the telescopic arm 3 can be extended and retracted to adjust the position of the supporting member 5 in the second direction. In actual use, when the drill rod 200 is transferred to the drilling platform, it is placed flat on the drilling platform surface. The drilling platform surface is usually arranged parallel to the horizontal plane so that the force on the entire drilling platform surface is kept balanced, and is gradually adjusted to a vertical position when it is lowered to the wellhead, that is, adjusted from a flat state to a vertical position. The drill rod 200 is adjusted to a vertical state. During the process of lifting the drill rod 200 from the drilling well to the drilling table, the drill rod 200 needs to be adjusted from the vertical state to the horizontal state. During this process, the supporting member 5 mainly supports the lower end portion of the drill rod 200, that is, the end of the drill rod 200 facing the wellhead. The supporting member 5 supports the drill rod 200, so that the drill rod 200 slowly changes from the horizontal state to the vertical state during the lowering process, and the gravity of the drill rod 200 causes the drill rod 200 to instantly change from the horizontal state to the vertical state, thereby causing excessive impact force on the wellhead. Alternatively, the drill rod 200 is supported during the lifting process, so that it is adjusted from the vertical state to the square state, thereby avoiding the drill rod 200 from generating a large impact force on the drilling table. The supporting member 5 is only used for support, and there is no need to grab the drill rod 200. The structure is simple, and the support is completed directly during the process of lowering the drill rod 200 for drilling, which is more efficient.

[0034] Specifically, in one embodiment, the drill rod supporting device 100 is installed and fixed on the drilling table through the base 1, and the height of the telescopic arm 3 in the horizontal direction is adjusted when the swing arm 3 swings, and the telescopic arm 3 is used to drive the supporting member 5 to move in the second direction. During actual use, the second direction is a direction parallel to the horizontal plane.

[0035] Furthermore, the first driving member 4 is a first linear driving member 4a, which is located on one side of the swing arm 2; the two ends of the first linear driving member 4a are respectively a first mounting end 41 and a first output end 42, the first mounting end 41 is hinged to the base 1, and the first output end 42 is hinged to a position on the swing arm 2 between the hinge end 22 and the free end 21, and the first output end 42 of the first linear driving member 4a is used to drive the swing arm 2 so that the free end 21 of the swing arm 2 swings around the hinge end 22.

[0036] It can be understood that the first driving member 4 is a first linear driving member 4a, which can be extended and retracted in a linear direction, specifically, a part of the first output end 42 thereof extends into the first mounting end 41 and can be extended and retracted relative to the first mounting end 41, thereby achieving the function of driving the swing arm 2. Moreover, since the first mounting end 41 of the first driving member 4 and the hinged end 22 of the swing arm 2 are both hinged to the base 1, when the output end of the first driving member 4 is extended and retracted, a force is applied to the swing arm 2 from the position where the first output end 42 is connected to the swing arm 2, so that the swing arm 2 rotates around the hinged end 22. Moreover, when in use, the first linear driving member 4a can also be regarded as a supporting structure that can support the swing arm 2.

[0037] Please combine Figure 2 Specifically, a triangular frame structure is formed between the first driving member 4, the swing arm 2 and the base 1. It can be understood that the first driving member 4 serves as one of the sides of the triangular frame structure with variable length. The angle between the swing arm 2 and the base 1 in the triangular frame structure can be changed, so as to drive the swing arm 2 to swing. In addition, the triangular frame structure is more stable and can better support and stabilize the swing arm 2.

[0038] Furthermore, the hinged end 22 of the swing arm 2 is hinged to the base 1 through the first rotating shaft 11, and the first mounting end 41 of the first linear driving member 4a is hinged to the base 1 through the second rotating shaft 12; the first rotating shaft 11 and the second rotating shaft 12 are arranged in parallel, so that when the first linear driving member 4a drives the swing arm 2 through the first output end 42, the free end 21 of the swing arm 2 swings around the first rotating shaft 11.

[0039] It can be understood that the swing arm 2 and the first linear drive member 4a are hinged to the base 1 through the first rotating shaft 11 and the second rotating shaft 12. The swing arm 2 rotates around the first rotating shaft 11 when it swings, and the first linear drive member 4a can rotate around the second rotating shaft 12. The first rotating shaft 11 and the second rotating shaft 12 are arranged in parallel, so that the rotation direction of the swing arm 2 and the first linear drive member 4a are consistent, and the first rotating shaft 11 has stable guiding properties when the swing arm 2 rotates, so that the swing arm 2 can maintain a stable state for rotation.

[0040] Among them, the first rotating shaft 11 and the second rotating shaft 12 are both cylindrical, and corresponding structures are provided on the hinged end 22 of the swing arm 2 and the mounting end of the first linear drive member 4a or through holes are opened for respectively cooperating and connecting with the first rotating shaft 11 and the second rotating shaft 12, and the cylindrical first rotating shaft 11 and the cylindrical second rotating shaft 12 can both better realize rotation.

[0041] Furthermore, the base 1 includes two mounting plates 13 spaced apart along the second direction, and an accommodating space 14 is formed between the two mounting plates 13. The first rotating shaft 11 and the second rotating shaft 12 are both arranged along the second direction, and both ends of the first rotating shaft 11 are respectively hinged to the two mounting plates 13, and both ends of the second rotating shaft 12 are respectively hinged to the two mounting plates 13. The hinged end 22 extends into the accommodating space 14 and is connected to the first rotating shaft 11, and the first mounting end 41 of the first linear drive member 4a extends into the accommodating space 14 and is connected to the second rotating shaft 12.

[0042] It can be understood that when supporting the drill rod 200, the swing arm 2 will eventually bear the force from the drill rod 200, and the force generated by the swing arm 2 is ultimately borne by the first rotating shaft 11 and the second rotating shaft 12. By connecting both ends of the first rotating shaft 11 and the second rotating shaft 12 to the mounting plates 13 respectively, the force borne by the first rotating shaft 11 and the second rotating shaft 12 is evenly distributed to the two mounting plates 13, and the structural stability is higher.

[0043] In this embodiment, the first rotating shaft 11 and the second rotating shaft 12 are both hinged to the mounting plate 13, that is, the first rotating shaft 11 and the second rotating shaft 12 can rotate on the mounting plate 13, and the first rotating shaft 11 and the swing arm 2 are relatively fixedly connected and do not rotate. When the first linear drive member 4a drives the swing arm 2 to swing, it drives the first rotating shaft 11 to rotate on the mounting plate 13. Similarly, the first linear drive member 4a is also fixedly connected to the second rotating shaft 12 and does not rotate.

[0044] In another embodiment, the first rotating shaft 11 and the second rotating shaft 12 are connected and relatively fixed to the mounting plate 13, the swing arm 2 is rotationally connected to the first rotating shaft 11, and the first linear driving member 4a is rotationally connected to the second rotating shaft 12. When the first linear driving member 4a drives the swing arm 2 to swing, it rotates around the first rotating shaft 11.

[0045] Furthermore, the telescopic arm 3 includes a sleeve 31, a telescopic rod 32 and a second driving member 33. The sleeve 31 is arranged along the second direction, and the sleeve 31 is connected to the free end 21 of the swing arm 2; the telescopic rod 32 is arranged along the second direction, and the two ends of the telescopic rod 32 along the second direction are respectively a first end and a second end, the first end extends into the sleeve 31 and is slidably connected to the sleeve 31, and the second end extends out of the sleeve 31 and is provided with a supporting member 5; the two ends of the second driving member 33 are respectively connected to the sleeve 31 and the second end of the telescopic rod 32, and the second driving member 33 is used to drive the telescopic rod 32 to extend and retract along the second direction.

[0046] It can be understood that when the telescopic rod 32 is extended and retracted relative to the sleeve 31, at least a portion of the telescopic rod 32 remains inserted into the sleeve 31. The sleeve 31 can prevent the position of the telescopic rod 32 from being shifted, and can also withstand the force of the drill rod 200. When the supporting member 5 supports the drill rod 200, the force applied by the drill rod 200 directly acts on the supporting member 5 and is then transmitted to the telescopic rod 32. At this time, the portion of the telescopic rod 32 extending into the sleeve 31 is used to keep the position of the entire telescopic rod 32 from being affected by the force. The sleeve 31 is the only structure of the entire telescopic arm 3 connected to the swing arm 2. It can also mainly prevent the entire telescopic arm 3 from bending when subjected to the force of the drill rod 200.

[0047] In addition, the telescopic rod 32 is driven by a separate second driving member 33, so the telescopic rod 32 and the sleeve 31 can be made of a more rigid and non-bending material, and the structures of the telescopic rod 32 and the sleeve 31 are simpler, and only a structure that can be coordinated for telescopic operation is required. Even if the telescopic rod 32 is worn due to long-term support of the drill rod 200 during use, only the telescopic rod 32 or the sleeve 31 needs to be replaced, and the maintenance cost is lower.

[0048] Specifically, in this embodiment, in order to make the connection between the sleeve 31 and the swing arm 2 more stable, the sleeve 31 adopts a non-cylindrical design, preferably a prismatic sleeve 31 and a telescopic rod 32, which not only have a stable structure but also will not rotate relative to the swing arm 2.

[0049] Furthermore, the second driving member 33 is a second linear driving member 33a, and the two ends of the second linear driving member 33a are respectively a second mounting end 331 and a second output end 332; the sleeve 31 and the telescopic rod 32 are respectively provided with a first hinge seat 35 and a second hinge seat 36, and the second mounting end 331 and the second output end 332 of the second linear driving member 33a are respectively hinged to the first hinge seat 35 and the second hinge seat 36; the second linear driving member 33a is arranged parallel to the sleeve 31, and the second linear driving member 33a drives the telescopic rod 32 to extend and retract along the second direction relative to the sleeve 31 through the second output end 332.

[0050] It can be understood that the second driving member 33 is a second linear driving member 33a, which also extends and retracts in the second direction during operation, so as to drive the telescopic rod 32 to extend and retract in the second direction. By arranging the second driving member 33 on the side of the telescopic arm 3 and parallel to the sleeve 31, the telescopic rod 32 can be quickly and synchronously driven to extend and retract when the first driving member 4 drives the telescopic movement. Moreover, since the second mounting end 331 and the second output end 332 of the first driving member 4 are respectively connected to the sleeve 31 and the telescopic rod 32, the first driving member 4 can stabilize the sleeve 31 and the telescopic rod 32 to a certain extent.

[0051] In some other embodiments, the second driving member 33 can also be arranged inside the sleeve 31, so that the second mounting end 331 abuts against the bottom of the sleeve 31, and the second output end 332 abuts against the end of the telescopic rod 32 extending into the sleeve 31, thereby driving the telescopic rod 32 to extend and retract.

[0052] Furthermore, the drill rod supporting device 100 also includes a support rod 6 , one end of which is connected to a position on the swing arm 2 close to the free end 21 , and the other end of which is connected to a position on the sleeve 31 close to the telescopic rod 32 .

[0053] It can be understood that one end of the support rod 6 is connected to a position on the sleeve 31 close to the telescopic rod 32, and the position on the sleeve 31 close to the telescopic rod 32 is also the part of the sleeve 31 that mainly bears the force. The support rod 6 can further enhance the load-bearing capacity of the sleeve 31 and prevent bending.

[0054] Furthermore, the second end of the telescopic rod 32 is provided with a connecting shaft 34 extending along the second direction, and the supporting member 5 is a roller 5a, which is sleeved on the connecting shaft 34 and can rotate around the connecting shaft 34. The outer edge of the roller 5a is used to support the drill rod 200 to support the drill rod 200.

[0055] It can be understood that by setting the roller 5a to support the drill rod 200, when the drill rod 200 is lowered from the drilling table to the wellhead, the outer edge of the roller 5a abuts against the drill rod 200 for support, and the drill rod 200 slides along the roller 5a into the drilling well, thereby efficiently supporting the drill rod 200 and lowering it to the drilling well.

[0056] Furthermore, a groove is formed on the outer edge of the roller 5 a along its circumference. The groove is formed by the outer edge of the roller 5 a being sunken inward. The groove is used to cooperate with the side of the drill rod 200 in sliding contact to support the drill rod 200 .

[0057] It can be understood that a groove 51 is provided on the outer edge of the roller 5a. When the roller 5a supports the drill rod 200, the side of the drill rod 200 slides in contact with the groove 51. The groove 51 can prevent the drill rod 200 from sliding sideways and thus detaching from the roller 5a.

[0058] Specifically, in this embodiment, the roller 5a is a V-wheel, and the groove 51 is a V-shaped groove. In other embodiments, the groove 51 may also be other shapes, such as a U-shaped groove.

[0059] Furthermore, the swing arm 2 includes a first swing arm portion 23 and a second swing arm portion 24, the first swing arm portion 23 and the second swing arm portion 24 are both arranged along the first direction, one end of the first swing arm portion 23 and one end of the second swing arm portion 24 are interconnected to form a connecting position 25, and the end of the first swing arm portion 23 away from the second swing arm portion 24 is a hinged end 22, and the end of the second swing arm portion 24 away from the first swing arm portion 23 is a free end 21, and the dimension of the first swing arm portion 23 along the third direction is gradually reduced from the connecting position 25 to the hinged end 22, and the dimension of the second swing arm portion 24 along the third direction is gradually reduced from the connecting position 25 to the free end 21, wherein the first direction, the second direction and the third direction are perpendicular to each other.

[0060] It can be understood that the swing arm 2 is divided into a first swing arm portion 23 and a second swing arm portion 24. The position where the first swing arm portion 23 and the second swing arm portion 24 are connected is a connection position 25. Figure 2 The position with the largest dimension in the z direction is located at the connection position 25, such as Figure 2 As shown, the dimension of the connection position 25 along the third direction is Figure 2 h in the figure indicates that the dimension of the first swing arm portion 23 along the third direction gradually decreases from the connection position 25 to the hinge end 22, and the dimension of the second swing arm portion 24 along the third direction gradually decreases from the connection position 25 to the free end 21. The dimension of the entire swing arm 2 along the second direction is the thickness, and the thickness of the swing arm 2 is uniformly set. When supporting the drill rod 200, the gravity of the drill rod 200 is the vertical force toward the vertical horizontal plane, and the above text has explained that the function of the swing arm 2 is to adjust the horizontal height of the telescopic rod 3, that is, the second direction is parallel to the horizontal plane. When supporting the drill rod 200 to be lowered to the wellhead, the force on the swing arm 2 in the second direction is very small, and the force on the third direction is relatively large. Moreover, as the swing arm rotates, the angle between the third direction and the vertical direction changes accordingly. Therefore, the force component in the third direction also changes. By setting the dimensions of the swing arm 2 in the third direction unevenly, the narrower they are closer to the two ends, the more in line with the structural stability design is achieved. This is beneficial for the swing arm 2 to maintain stability when supporting the drill rod 200 under force. The larger size of the connection position 25 makes it difficult for the swing arm 2 to bend after being subjected to force, and the structure is more stable.

[0061] Furthermore, position sensors are disposed inside the first linear drive member 4a and inside the second linear drive member 33a.

[0062] It can be understood that the position sensor arranged in the first linear drive member 4a can monitor and transmit the position movement information of the first output terminal 42 on the first linear drive member 4a in real time, and the position sensor arranged in the second linear drive member 33a can monitor and transmit the position movement information of the second output terminal 332 on the second linear drive member 33a in real time, so as to facilitate automated remote control.

All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
