Description

Technical Field

[0001] This utility model belongs to the field of oil drilling rig technology, and in particular relates to a traveling block fixing device for oil drilling rigs. Background Technology

[0002] In oil drilling rigs, the traveling block is typically suspended from the derrick by steel cables, and the weight of the traveling block and its suspension components is borne by the tensioned steel cables. However, because steel cables are flexible, they can only withstand tensile force, thus providing only a vertically upward force to the traveling block. When the derrick is being raised, lowered, or transported, it is no longer in a vertical position, and the steel cables can no longer provide effective support for the traveling block. Furthermore, during the lowering or transporting of the main rope, the steel cables may loosen and cease to provide support for the traveling block. Utility Model Content

[0003] To overcome the shortcomings of existing technology, this utility model provides a traveling block fixing device for oil drilling rigs, which can provide continuous and stable support for the traveling block during derrick hoisting, derrick lowering, oil drilling rig cable rewinding, or oil drilling rig transportation.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A traveling block fixing device for an oil drilling rig includes a first limiting component for restricting the horizontal movement of the traveling block relative to the derrick and a second limiting component for restricting the vertical downward movement of the traveling block relative to the derrick during derrick hoisting, derrick lowering, oil drilling rig rewinding, or oil drilling rig transportation.

[0006] The beneficial effects of adopting the above technical solution are as follows: the first limiting component can restrict the horizontal movement of the traveling block relative to the derrick, and in the derrick hoisting, derrick lowering, oil drilling rig rewinding, or oil drilling rig transportation conditions, the second limiting component can restrict the vertical downward movement of the traveling block relative to the derrick. That is, in the derrick hoisting, derrick lowering, oil drilling rig rewinding, or oil drilling rig transportation conditions, the second limiting component can be used in conjunction with the first limiting component to provide continuous and stable support for the traveling block.

[0007] Furthermore, the second limiting assembly includes a support member fixedly connected to one side of the derrick and a tilting member hinged at one end to the other side of the derrick;

[0008] The first limiting component includes several limiting components that are vertically and fixedly connected to the flipping component;

[0009] When the flipper is flipped to the first state, the support provides support for the free end of the flipper, the flipper provides vertical upward support for the traveling carriage, and several limiting members restrict the horizontal movement of the traveling carriage; wherein, the first state is the horizontal state.

[0010] The beneficial effects of adopting the above technical solution are as follows: when the flipping component flips to the horizontal state, it can provide vertical upward support for the traveling carriage, and several limiting components can flip to the vertical state with the flipping component, so that the several vertical limiting components cooperate to restrict the horizontal movement of the traveling carriage.

[0011] Furthermore, the derrick is equipped with a first driving component for driving the tilting component to the second state. When the tilting component is tilted to the second state, neither the tilting component nor the limiting component is on the lifting path of the traveling carriage.

[0012] The beneficial effects of adopting the above technical solution are as follows: This setting ensures that when the flipping component flips to the second state, the flipping component and the limiting component will not affect the normal lifting and lowering of the traveling block, thereby ensuring that the traveling block can normally lift and lower the drill.

[0013] Furthermore, the first driving component is a traction device located above the tilting component. The derrick is hinged to one side of the tilting component and the traction device is fixedly connected to it. The traction end of the traction device is fixedly connected to the free end of the tilting component. The tilting angle of the tilting component from the first state to the second state is no greater than 90°.

[0014] The beneficial effects of adopting the above technical solution are as follows: when the traction device is retracted, it can pull the flipping part to reset from the horizontal state to the second state; and since the flipping angle of the flipping part from the first state to the second state is no more than 90°, when the traction device is released, the flipping part can flip to the horizontal state by its own gravity, and the traction device can play a buffering role for the flipping part.

[0015] Furthermore, the derrick is equipped with a first locking mechanism for locking the overturning component in the second state.

[0016] The beneficial effects of adopting the above technical solution are as follows: when the flipping component flips to the second state, the first locking mechanism can lock the flipping component to stably restrict the flipping component on the derrick, thereby avoiding any impact on the normal tripping of the traveling block.

[0017] Furthermore, the first limiting component includes a first guide rail connected to the derrick and a connector fixedly connected to the traveling trolley and moving vertically on the first guide rail;

[0018] The second limiting component includes a second locking mechanism with a retractable locking pin; when the retractable locking pin extends, it restricts the relative vertical movement of the traveling carriage and the first guide rail; when the retractable locking pin retracts, it no longer restricts the relative vertical movement of the traveling carriage and the first guide rail.

[0019] The beneficial effects of adopting the above technical solution are as follows: Since the connecting piece can move vertically on the first guide rail, the traveling trolley can move vertically on the derrick. Moreover, the first guide rail can generally restrict the horizontal movement of the connecting piece, thus restricting the horizontal movement of the traveling trolley on the derrick. At the same time, after the telescopic locking pin extends, it restricts the relative vertical movement of the traveling trolley and the first guide rail, so as to provide vertical upward support for the traveling trolley. After the telescopic locking pin retracts, it no longer restricts the relative vertical movement of the traveling trolley and the first guide rail, so as to avoid affecting the normal lifting and lowering of the traveling trolley.

[0020] Furthermore, a second horizontal locking mechanism is fixedly connected to the first guide rail, and the extension path of the retractable locking pin intersects with the movement path of the connecting piece.

[0021] The beneficial effects of adopting the above technical solution are as follows: the retractable locking pin can extend to the movement path of the connecting piece to restrict the vertical downward movement of the traveling carriage, so as to provide vertical upward support for the traveling carriage.

[0022] Furthermore, a lateral adjustment component for adjusting the lateral position of the first guide rail and / or a longitudinal adjustment component for adjusting the longitudinal position of the first guide rail are connected between the derrick and the first guide rail.

[0023] Furthermore, the lateral adjustment assembly includes a second guide rail connected to the derrick, a first connecting block slidably connected to the second guide rail, and the first connecting block is connected to the first guide rail; a first elastic element and a first linear drive mechanism are respectively provided between the first connecting block and both sides of the derrick, and the driving direction of the first linear drive mechanism matches the sliding direction of the first connecting block.

[0024] The beneficial effects of adopting the above technical solution are as follows: when the first linear drive mechanism extends, it can push the first connecting block to move laterally toward the first elastic member and compress the first elastic member; when the first linear drive mechanism retracts, the first elastic member rebounds and pushes the first connecting block to move laterally toward the first linear drive mechanism.

[0025] Furthermore, the longitudinal adjustment assembly includes a second connecting block connected to the derrick, a sliding shaft slidably connected to the second connecting block along the longitudinal direction, and a first guide rail connected to the sliding shaft; a second elastic element and a second linear drive mechanism are fixedly connected to the sliding shaft, one end of the second elastic element acts on one side of the second connecting block, and the output end of the second linear drive mechanism acts on the other side of the second connecting block.

[0026] The beneficial effects of adopting the above technical solution are as follows: when the second linear drive mechanism extends and acts on the other side of the second connecting block, it can pull the sliding shaft to move longitudinally and compress the second elastic element; when the second linear drive mechanism retracts, the second elastic element rebounds, causing the sliding shaft to move longitudinally in the opposite direction.

[0027] The beneficial effects of this utility model are as follows:

[0028] The first limiting component restricts the horizontal movement of the traveling block relative to the derrick. In the derrick hoisting, derrick lowering, oil rig rewinding, or oil rig transport operations, the second limiting component restricts the vertical downward movement of the traveling block relative to the derrick. That is, in the derrick hoisting, derrick lowering, oil rig rewinding, or oil rig transport operations, the second limiting component can be used in conjunction with the first limiting component to provide continuous and stable support for the traveling block.

[0045] The present invention will be further described below with reference to the accompanying drawings.

[0046] This utility model provides a device for fixing the traveling block of an oil drilling rig, such as... Figure 1-12 As shown, it includes a first limiting component for restricting the horizontal movement of the traveling block 2 relative to the derrick 1 and a second limiting component for restricting the vertical downward movement of the traveling block 2 relative to the derrick 1 during the derrick 1 hoisting operation, the derrick 1 lowering operation, the oil drilling rig rewinding operation, or the oil drilling rig transportation operation.

[0047] Understandably, the first limiting component can restrict the horizontal movement of the traveling block 2 relative to the derrick 1, and when the derrick 1 is in the hoisting, lowering, or transporting phases, the second limiting component can restrict the vertical downward movement of the traveling block 2 relative to the derrick 1. That is, when the derrick 1 is in the hoisting, lowering, or transporting phases, the second limiting component can work in conjunction with the first limiting component to provide continuous and stable support for the traveling block 2.

[0048] Example 1

[0049] In this embodiment, as Figure 1 and Figure 2 As shown, the second limiting assembly includes a support member 6 fixedly connected to one side of the derrick 1 and a flipping member 3 hinged at one end to the other side of the derrick 1; the first limiting assembly includes several limiting members 4 vertically fixedly connected to the flipping member 3; when the flipping member 3 is flipped to the first state, the support member 6 provides support for the free end of the flipping member 3, the flipping member 3 provides vertical upward support for the traveling trolley 2, and the several limiting members 4 restrict the horizontal movement of the traveling trolley 2; wherein, the first state is a horizontal state.

[0050] It is understandable that when the flipping component 3 is flipped to the horizontal state, it can provide vertical upward support for the traveling carriage 2, and several limiting components 4 can be flipped to the vertical state along with the flipping component 3 so that the several vertical limiting components 4 cooperate to restrict the horizontal movement of the traveling carriage 2.

[0051] It should be noted that the oil drilling rig traveling block fixing device can be set at any position in the height direction of the derrick 1. Preferably, the oil drilling rig traveling block fixing device is set at a low position of the derrick 1 to facilitate on-site observation and operation.

[0052] Preferably, such as Figure 3 As shown, the derrick 1 is provided with a first driving member 7 for driving the tilting member 3 to tilt to the second state. When the tilting member 3 tilts to the second state, neither the tilting member 3 nor the limiting member 4 is on the lifting path of the traveling carriage 2; in addition, the supporting member 6 is also not on the lifting path of the traveling carriage 2.

[0053] Understandably, this configuration ensures that when the rotating component 3 is rotated to the second state, the rotating component 3 and the limiting component 4 will not affect the normal lifting and lowering of the traveling block 2, thereby ensuring that the traveling block 2 can normally raise and lower the drill bit.

[0054] It should be noted that during normal tripping and hoisting operations of the traveling block 2, the steel cable is tensioned to provide force to the traveling block 2, and the resetting component 3 and its limiting component 4 are not located in the lifting and lowering path of the traveling block 2. During the hoisting operation of the derrick 1, the lowering operation of the derrick 1, the oil drilling rig rewinding operation, or the oil drilling rig transportation operation, the steel cable is loosened and no force is provided to the traveling block 2. The resetting component 3 is flipped to the horizontal to provide vertical upward support force to the traveling block 2. Multiple vertical limiting components 4 together restrict the horizontal movement of the traveling block 2, thereby providing continuous and stable support to the traveling block 2.

[0055] Preferably, such as Figure 1-3 As shown, the first driving component 7 is a traction device located above the flipping component 3. The derrick 1 is hinged to one side of the flipping component 3 and the traction device is fixedly connected. The traction end of the traction device is fixedly connected to the free end of the flipping component 3. The flipping angle of the flipping component 3 from the first state to the second state is not greater than 90°.

[0056] It is understandable that when the traction device retracts, it can pull the flipping part 3 back from the horizontal state to the second state; and since the flipping angle of the flipping part 3 from the first state to the second state is no more than 90°, when the traction device is released, the flipping part 3 can flip to the horizontal state by its own gravity, and the traction device can buffer the flipping part 3.

[0057] It should be noted that the flipping component 3 can be two flipping rods. When the two flipping rods are flipped to the horizontal, they provide support for both sides of the traveling carriage 2. The limiting component 4 can be a limiting rod. Two limiting rods are set on each of the two flipping rods. These four limiting rods clamp the traveling carriage 2 at the four corners to restrict the horizontal movement of the traveling carriage 2. In addition, the traction device can be two winches. One end of the traction rope of the two winches is connected to the free end of the two flipping rods respectively.

[0058] It should also be noted that, in addition to relying on its own gravity, the flipping component 3 can also be flipped to a horizontal state by means of spring force and hydraulic pressure.

[0059] Preferably, the derrick 1 is provided with a first locking mechanism 5 for locking the flipping component 3 in the second state.

[0060] Understandably, when the flipper 3 flips to the second state, the first locking mechanism 5 can lock the flipper 3 to stably restrict the flipper 3 on the derrick 1, thereby avoiding any impact on the normal tripping of the traveling block 2.

[0061] It should be noted that two first locking mechanisms 5 can be provided, and the first locking mechanism 5 can be a cylinder, hydraulic cylinder or electric push rod, etc. When the two flipping parts 3 are flipped to the second state, one end of the two first locking mechanisms 5 extends out and can block the free ends of the two flipping parts 3 respectively, so as to prevent the flipping parts 3 from flipping to the horizontal state, thereby achieving the purpose of locking the flipping parts 3.

[0062] The operation method for fixing the traveling trolley 2 in this embodiment is as follows:

[0063] One end of the first locking mechanism 5 retracts to release the locking flipper 3;

[0064] As the first driving component 7 is extended outward, the flipping component 3 flips around the hinge point under its own gravity until the free end of the flipping component 3 flips onto the support component 6.

[0065] The trolley 2 is lowered onto the flipping component 3 and locked between multiple limiting components 4. The flipping component 3 provides support for the trolley 2, and the multiple limiting components 4 restrict the horizontal movement of the trolley 2, thereby fixing the trolley 2.

[0066] The method for releasing the fixed travel carriage 2 in this embodiment is as follows:

[0067] Lift the traveling carriage 2 so that it disengages from the flipping component 3 and the multiple limiting components 4;

[0068] The first driving member 7 retracts inward so that the flipping member 3 flips around the hinge point to the initial position of the second state.

[0069] One end of the first locking mechanism 5 extends out to lock the flipping part 3, thereby releasing the travel carriage 2 from being fixed.

[0070] Example 2

[0071] In this embodiment, as Figure 4-7 As shown, the first limiting component includes a first guide rail 8 fixedly connected to the derrick 1 and a connector 9 fixedly connected to the traveling trolley 2 and moving vertically on the first guide rail 8; wherein, the first guide rail 8 provides a track for the connector 9 to slide along the height direction of the derrick 1, and the track can limit the horizontal movement of the connector 9;

[0072] The second limiting component includes a second locking mechanism 10 with a retractable locking pin; when the retractable locking pin extends, it restricts the relative vertical movement of the traveling carriage 2 and the first guide rail 8; when the retractable locking pin retracts, it no longer restricts the relative vertical movement of the traveling carriage 2 and the first guide rail 8.

[0073] The second locking mechanism 10 can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod, and the output end of the hydraulic cylinder, pneumatic cylinder, or electric push rod is fixedly connected to a retractable locking pin.

[0074] Understandably, since the connecting piece 9 can move vertically on the first guide rail 8, the traveling trolley 2 can move vertically on the derrick 1. And the first guide rail 8 can generally restrict the horizontal movement of the connecting piece 9, so it can restrict the horizontal movement of the traveling trolley 2 on the derrick 1. At the same time, after the telescopic locking pin extends, it restricts the relative vertical movement of the traveling trolley 2 and the first guide rail 8 to provide vertical upward support for the traveling trolley 2. After the telescopic locking pin retracts, it no longer restricts the relative vertical movement of the traveling trolley 2 and the first guide rail 8, so as to avoid affecting the normal lifting and lowering of the traveling trolley 2.

[0075] It should be noted that under normal tripping conditions of the traveling block 2, the steel cable is tensioned to supply force to the traveling block 2, and the retractable locking pin of the second locking mechanism 10 retracts. Under conditions of derrick 1 hoisting, derrick 1 lowering, oil drilling rig rewinding, or oil drilling rig transportation, the steel cable is loosened and no force is supplied to the traveling block 2. The retractable locking pin of the second locking mechanism 10 extends to restrict the vertical movement of the traveling block 2. At the same time, the first guide rail 8 restricts the horizontal movement of the connecting piece 9 and the traveling block 2 on it, thereby providing continuous and stable support for the traveling block 2.

[0076] It should be noted that wear-resistant plates 11 or rollers 12 can be provided on both sides of the connector 9 to facilitate vertical movement in the first guide rail 8.

[0077] Preferably, a horizontal second locking mechanism 10 is fixedly connected to the first guide rail 8, and the extension path of the retractable locking pin intersects with the movement path of the connecting member 9.

[0078] Understandably, the retractable locking pin can extend into the movement path of the connector 9 to restrict the vertical downward movement of the traveling carriage 2 in order to provide vertical upward support for the traveling carriage 2.

[0079] It should be noted that the second locking mechanism 10 can be set at any position in the height direction of the derrick 1. Preferably, the second locking mechanism 10 is set at a low position of the derrick 1 for on-site observation and operation.

[0080] It should also be noted that the second locking mechanism 10 can also be directly installed on the traveling carriage 2, so that the traveling carriage 2 can be locked when it slides to any position on the first guide rail 8.

[0081] The operation method for fixing the traveling trolley 2 in this embodiment is as follows:

[0082] Install connector 9 onto traveling carriage 2;

[0083] Insert the connector 9 into the first guide rail 8 so that the traveling trolley 2 can only move up and down along the derrick 1;

[0084] Extend the retractable locking pin of the second locking mechanism 10 to restrict the travel carriage 2 from moving up and down along the derrick 1, thereby fixing the travel carriage 2.

[0085] The method for releasing the fixed travel carriage 2 in this embodiment is as follows:

[0086] The retractable locking pin of the second locking mechanism 10 retracts, allowing the traveling carriage 2 to move up and down along the derrick 1, thereby releasing the traveling carriage 2 from its fixed position.

[0087] Example 3

[0088] Based on Example 2, such as Figure 8-12 As shown, in this embodiment, a lateral adjustment component for adjusting the lateral position of the first guide rail 8 and / or a longitudinal adjustment component for adjusting the longitudinal position of the first guide rail 8 are connected between the derrick 1 and the first guide rail 8.

[0089] Preferably, such as Figure 8 and Figure 9 As shown, the lateral adjustment assembly includes a second guide rail 13 fixedly connected to the derrick 1, a first connecting block 14 slidably connected to the second guide rail 13 along the lateral direction, and a first guide rail 8 can be connected to the first connecting block 14; a first elastic element 15 and a first linear drive mechanism 16 are respectively provided between the first connecting block 14 and both sides of the derrick 1, the driving direction of the first linear drive mechanism 16 matches the sliding direction of the first connecting block 14; wherein, the first linear drive mechanism 16 can be a hydraulic cylinder, the first elastic element 15 can be a spring, and the extension and retraction direction of the first elastic element 15 can match the sliding direction of the first connecting block 14.

[0090] Understandably, high-pressure hydraulic oil is supplied to one end of the first linear drive mechanism 16. When the piston rod of the first linear drive mechanism 16 extends, it can push the first connecting block 14 to move laterally toward the first elastic member 15 and compress the first elastic member 15, thereby causing the first guide rail 8 to move laterally. When the pressure is released at one end of the first linear drive mechanism 16, the first elastic member 15 rebounds, causing the piston rod of the first linear drive mechanism 16 to retract. At the same time, the first elastic member 15 pushes the first connecting block 14 to move laterally toward the first linear drive mechanism 16, thereby causing the first guide rail 8 to move laterally in the opposite direction.

[0091] It should be noted that, as Figure 10As shown, the first connecting block 14 is a T-shaped block, and the second guide rail 13 is provided with a T-shaped groove along the length direction for sliding connection of the first connecting block 14, so that the first connecting block 14 can only slide in the second guide rail 13 and prevent the first connecting block 14 from coming off the second guide rail 13.

[0092] Preferably, such as Figure 11 As shown, the longitudinal adjustment assembly includes a second connecting block 17 connected to the derrick 1. Two sliding shafts 19 are slidably connected to the second connecting block 17 along the longitudinal direction. The two sliding shafts 19 are respectively fixedly connected to both sides of the first guide rail 8. A second elastic element 20 and a second linear drive mechanism 18 are fixedly connected to the sliding shafts 19. One end of the second elastic element 20 acts on one side of the second connecting block 17, and the output end of the second linear drive mechanism 18 acts on the other side of the second connecting block 17. The second linear drive mechanism 18 can be a hydraulic cylinder, and the second elastic element 20 can be a spring. The extension and retraction direction of the second elastic element 20 can match the sliding direction of the sliding shaft 19.

[0093] Understandably, when high-pressure hydraulic oil is introduced into one end of the second linear drive mechanism 18, and the piston rod of the second linear drive mechanism 18 extends and acts on the other side of the second connecting block 17, it can pull the sliding shaft 19 to move longitudinally and compress the second elastic element 20; when the pressure is released at one end of the second linear drive mechanism 18, the second elastic element 20 rebounds, causing the second linear drive mechanism 18 to retract and the sliding shaft 19 to move longitudinally in the opposite direction.

[0094] like Figure 12 As shown, when both the lateral adjustment component and the longitudinal adjustment component are set at the same time, the first connecting block 14 of the lateral adjustment component and the second connecting block 17 of the longitudinal adjustment component can be the same component, so that the first guide rail 8 can be adjusted both laterally and longitudinally, which is beneficial to arbitrarily adjust the horizontal position of the first guide rail 8 relative to the derrick 1.
