Description

Technical Field

[0001] This utility model relates to the field of oil drilling technology, and in particular to a drill bit guide belt buckle device. Background Technology

[0002] In oil drilling operations, the current practice of connecting PDC drill bits with lead-ahead couplings on-site generally involves multiple people working together to lift and rotate the drill bit to perform the lead-ahead coupling. In high-frequency operation scenarios such as oil drilling and geological exploration, the rapid connection between the drill bit and the lead-ahead coupling structure is a key factor affecting operational efficiency.

[0003] When the drill bit guide belt buckle device is used in high-frequency operation scenarios, the operation of the drill bit guide belt buckle in the existing technology usually relies on manual operation. The operator needs to manually adjust the position of the drill bit and achieve the engagement of the drill bit and guide belt buckle through repeated rotation and trial and error. During this process, the drill bit clamping stability is poor, and the alignment accuracy is easily insufficient due to human operation errors. At the same time, manually rotating the drill bit is time-consuming and labor-intensive. Especially in operation scenarios that require frequent drill bit changes, the above problems will significantly reduce the overall operation efficiency.

[0004] Therefore, to address the issue of ineffectively improving overall drilling efficiency when used in high-frequency operation scenarios, a drill bit guide buckle device can be designed. When used in high-frequency operation scenarios, the four-jaw pin-type cover plate of the wellhead rotary table is first fixedly connected to the wellhead rotary table via multiple sets of bottom pins. Then, the position of the fixed plate is adjusted so that its central axis is aligned with the bottom of the pre-installed drill bit, ensuring the subsequent drill bit alignment accuracy. Next, the drill bit to be guided is smoothly placed above the fixed plate. At this point, the drill bit is positioned between two symmetrically arranged arc-shaped seats. The operator simultaneously pulls the locking mechanisms on the outer circumference of both arc-shaped seats upwards, and then pushes the two arc-shaped seats inwards. When the flexible inner wall surface of the two arc-shaped seats is in contact with the drill bit... When the outer circumference is fully engaged, the pushing stops and the locking mechanisms on both sides are released, achieving precise locking of the arc-shaped seats. At this time, the drill bit is firmly clamped by the two sets of arc-shaped seats, preventing slippage or tilting during operation. After the drill bit is clamped, the support cylinder is rotated. Since the inner cavity of the support cylinder is threaded to the outer wall of the support column, the support cylinder rises vertically along the support column during rotation. At the same time, the clamped drill bit is driven to rotate synchronously and move upward through the fixed plate. During the upward movement, the drill bit gradually engages with the upper guide belt buckle structure, finally completing the guide belt buckle operation. In summary, this device replaces manual rotation with a mechanized upward rotation design, shortens the guide belt buckle time, and can drive drill bits of different sizes to complete the upward rotation. It is especially suitable for high-frequency operation scenarios and effectively improves the overall efficiency of drilling operations. Utility Model Content

[0005] In order to overcome the problem that in the use of handrail support components, the operation of the drill bit guide belt buckle in the existing technology usually relies on manual operation, which results in poor drill bit clamping stability, insufficient centering accuracy due to human operation errors, and high labor intensity, it is not convenient to effectively improve the overall efficiency of drilling operations when used in high-frequency operation scenarios.

[0006] The technical solution of this utility model is as follows: a drill bit guide buckle device, including a wellhead rotary table four-jaw pin-type cover plate, with multiple sets of pin columns fixedly installed at the bottom of the wellhead rotary table four-jaw pin-type cover plate, and a scraper gripping type stabilizing base, with a scraper gripping type stabilizing base fixedly installed above the wellhead rotary table four-jaw pin-type cover plate, a support column fixedly installed above the scraper gripping type stabilizing base, a support cylinder that can move vertically fitted above the support column, the inner cavity of the support cylinder being threadedly connected to the outer wall of the support column, a fixed plate fixedly installed at the upper end of the support cylinder, and an arc-shaped seat that can move laterally symmetrically arranged above the fixed plate, with a flexible surface provided on the inner wall of the arc-shaped seat.

[0007] Preferably, when the drill bit guide buckle device is used in high-frequency operation scenarios, firstly, the four-jaw pin-type cover plate of the wellhead rotary table is fixedly connected to the wellhead rotary table through multiple sets of pins at the bottom. Then, the position of the fixed plate is adjusted so that its central axis is on the same vertical axis as the bottom of the pre-installed drill bit, ensuring the subsequent drill bit alignment accuracy. Then, the drill bit to be guided buckle is placed smoothly on the fixed plate. At this time, the drill bit is located between two sets of symmetrically arranged arc-shaped seats. The operator pulls the locking mechanism on the outer circumference of the arc-shaped seats upwards simultaneously, and then pushes the arc-shaped seats inwards. When the flexible inner wall surface of the arc-shaped seats is completely in contact with the outer circumference of the drill bit, the pushing is stopped and the locking mechanism on both sides is released, realizing... The precise locking of the arc-shaped seats ensures the drill bit is securely clamped by two sets of arc-shaped seats, preventing slippage or tilting during operation. Once the drill bit is clamped, the support cylinder rotates. Because the inner cavity of the support cylinder is threaded to the outer wall of the support column, the support cylinder rises vertically along the support column during rotation. Simultaneously, the clamped drill bit rotates and moves upward through the fixed plate. As the drill bit moves upward, it gradually engages with the upper guide belt buckle structure, ultimately completing the guide belt buckle operation. In summary, this device replaces manual rotation with a mechanized upward rotation design, shortening the guide belt buckle time. It can also drive drill bits of different sizes to complete the upward rotation, making it particularly suitable for high-frequency operation scenarios and effectively improving the overall efficiency of drilling operations.

[0008] Preferably, two sets of guide grooves are symmetrically opened on the upper surface of the fixed plate, and guide rods are fixedly installed inside the guide grooves, with guide blocks sleeved on the side walls of the guide rods.

[0009] Preferably, the guide block and the guide rod are slidably connected, and the bottom surface of the arc-shaped seat is fixedly connected to the top surface of the guide blocks on both sides respectively.

[0010] Preferably, a fixing block is fixedly installed on the outer circumference of the arc-shaped seat, and a locking rod that can move vertically is installed through the inside of the fixing block. Multiple sets of locking holes are symmetrically opened on the upper surface of the fixing plate, and the lower end of the locking rod is engaged with the inside of the locking hole.

[0011] Preferably, a locking ring is fixedly installed on the upper side wall of the locking rod, and a locking spring is fixedly installed on the bottom surface of the locking ring, with the lower end of the locking spring fixedly connected to the upper surface of the fixing block.

[0012] Preferably, the outer circumferential surface of the support column is provided with an external thread groove, and the inner wall of the inner cavity of the support cylinder is provided with an internal thread groove, with the external thread groove and the internal thread groove being threadedly matched.

[0013] Preferably, multiple sets of rotating handles are fixedly installed on the outer circumferential surface of the support cylinder, and the rotating handles are arranged in a circular array.

[0014] The beneficial effects of this utility model are:

[0015] When the drill bit guide belt buckle device is used in high-frequency operation scenarios, firstly, the four-jaw pin-type cover plate of the wellhead rotary table is fixedly connected to the wellhead rotary table through multiple sets of pins at the bottom. Then, the position of the fixed plate is adjusted so that its central axis is on the same vertical axis as the bottom of the pre-installed drill bit, ensuring the subsequent drill bit alignment accuracy. Then, the drill bit to be guided belt buckle is placed smoothly on the fixed plate. At this time, the drill bit is located between two sets of symmetrically arranged arc-shaped seats. The operator pulls the locking mechanism on the outer circumference of the arc-shaped seats upwards simultaneously, and then pushes the arc-shaped seats inwards. When the flexible inner wall surface of the arc-shaped seats is completely in contact with the outer circumference of the drill bit, the pushing is stopped and the locking mechanism on both sides is released, realizing the arc-shaped buckle. With the precise locking of the seats, the drill bit is firmly clamped by two sets of arc-shaped seats, preventing slippage or tilting during operation. After the drill bit is clamped, the support cylinder rotates. Since the inner cavity of the support cylinder is threaded to the outer wall of the support column, the support cylinder rises vertically along the support column during rotation. At the same time, the clamped drill bit rotates synchronously and moves upward through the fixed plate. During the upward movement, the drill bit gradually engages with the upper guide belt buckle structure, finally completing the guide belt buckle operation. In summary, this device replaces manual rotation with mechanized upward rotation design, shortens the guide belt buckle time, and can drive drill bits of different sizes to complete the upward rotation. It is especially suitable for high-frequency operation scenarios and effectively improves the overall efficiency of drilling operations. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Example 1

[0023] Please see Figure 1 and Figure 3 This utility model provides an embodiment: a drill bit guide buckle device, including a wellhead rotary table four-jaw pin-type cover plate 1, with multiple sets of pin columns fixedly installed at the bottom of the wellhead rotary table four-jaw pin-type cover plate 1, and a scraper gripping type stabilizing base 2. The scraper gripping type stabilizing base 2 is fixedly installed above the wellhead rotary table four-jaw pin-type cover plate 1, and a support column 3 is fixedly installed above the scraper gripping type stabilizing base 2. A support cylinder 4 that can move vertically is sleeved on the support column 3. The inner cavity of the support cylinder 4 is threadedly connected to the outer wall of the support column 3. A fixed plate 5 is fixedly installed at the upper end of the support cylinder 4. A horizontally movable arc-shaped seat 6 is symmetrically arranged above the fixed plate 5. The inner wall of the arc-shaped seat 6 is provided with a flexible surface.

[0024] When the drill bit guide belt buckle device is used in high-frequency operation scenarios, firstly, the four-jaw pin-type cover plate 1 of the wellhead rotary table is fixedly connected to the wellhead rotary table through multiple sets of bottom pins. Then, the position of the fixed plate 5 is adjusted so that its central axis is on the same vertical axis as the bottom of the pre-installed drill bit, ensuring the subsequent drill bit alignment accuracy. Then, the drill bit to be guided belt buckle is placed smoothly on the fixed plate 5. At this time, the drill bit is located between two sets of symmetrically arranged arc-shaped seats 6. The operator pulls the locking mechanism on the outer circumference of the arc-shaped seats 6 upwards simultaneously, and then pushes the arc-shaped seats 6 inwards. When the flexible inner wall surface of the arc-shaped seats 6 is completely in contact with the outer circumference of the drill bit, the pushing is stopped and the locking mechanism on both sides is released to achieve the arc-shaped buckle. With the precise locking of seat 6, the drill bit is firmly clamped by two sets of arc-shaped seats 6, preventing slippage or tilting during operation. After the drill bit is clamped, the support cylinder 4 rotates. Since the inner cavity of the support cylinder 4 is threaded to the outer wall of the support column 3, the support cylinder 4 rises vertically along the support column 3 during rotation. At the same time, the clamped drill bit rotates synchronously and moves upward through the fixed plate 5. During the upward movement, the drill bit gradually engages with the upper guide belt buckle structure, finally completing the guide belt buckle operation. In summary, this device replaces manual rotation with mechanized upward rotation design, shortens the guide belt buckle time, and can drive drill bits of different sizes to complete the upward rotation. It is especially suitable for high-frequency operation scenarios and effectively improves the overall efficiency of drilling operations.

[0025] Example 2

[0026] Please see Figure 3 and Figure 4 The difference from Embodiment 1 is that two sets of guide grooves 7 are symmetrically opened on the upper surface of the fixed plate 5, and guide rods 8 are fixedly installed inside the guide grooves 7. Guide blocks 9 are sleeved on the side walls of the guide rods 8, and the guide blocks 9 are slidably connected to the guide rods 8. The bottom surfaces of the arc-shaped seat 6 are fixedly connected to the top surfaces of the guide blocks 9 on both sides respectively.

[0027] The bottom sides of the arc-shaped seat 6 are fixedly connected to the top surface of the guide block 9. The guide block 9 slides smoothly along the guide rod 8 in the guide groove 7 on the upper surface of the fixed plate 5. The sliding cooperation between the guide rod 8 and the guide block 9 ensures the stability of the lateral movement of the arc-shaped seat 6 and avoids deviation.

[0028] Example 3

[0029] Please see Figure 3 and Figure 4 The difference from Embodiment 1 is that a fixing block 10 is fixedly provided on the outer peripheral surface of the arc-shaped seat 6, and a locking rod 11 that can move vertically is provided through the inside of the fixing block 10. Multiple sets of locking holes 12 are symmetrically opened on the upper surface of the fixing plate 5, and the lower end of the locking rod 11 is engaged with the inside of the locking hole 12.

[0030] The lower end of the locking rod 11 is inserted into the corresponding locking hole 12 on the fixed plate 5 to achieve precise locking of the arc-shaped seat 6.

[0031] Example 4

[0032] Please see Figure 2 and Figure 4 The difference from Embodiment 3 is that a locking ring 13 is fixedly provided on the upper side wall of the locking rod 11, and a locking spring 14 is fixedly provided on the bottom surface of the locking ring 13. The lower end of the locking spring 14 is fixedly connected to the upper surface of the fixing block 10.

[0033] Release the locking rods 11 on both sides. The rebound force of the locking spring 14 drives the locking rod 11 to move downward through the locking ring 13. The lower end of the locking rod 11 is inserted into the corresponding locking hole 12 on the fixed plate 5.

[0034] Example 5

[0035] Please see Figure 2 and Figure 4 The difference from Embodiment 1 is that the outer peripheral surface of the support column 3 is provided with an external thread groove 15, and the inner wall of the inner cavity of the support cylinder 4 is provided with an internal thread groove 16. The external thread groove 15 and the internal thread groove 16 are threadedly matched with each other. Multiple sets of rotating handles 17 are fixedly provided on the outer peripheral surface of the support cylinder 4, and the rotating handles 17 are arranged in a circular array.

[0036] Rotating the handle 17 causes the support cylinder 4 to rotate. Since the internal thread groove 16 on the inner wall of the support cylinder 4 is threadedly matched with the external thread groove 15 on the outer circumference of the support column 3, the support cylinder 4 rises vertically along the support column 3 during rotation.

[0037] Example 6

[0038] Please see Figure 1 and Figure 3 This utility model provides an embodiment: a drill bit guide buckle device, including a wellhead rotary table four-jaw pin-type cover plate 1, with multiple sets of pin columns fixedly installed at the bottom of the wellhead rotary table four-jaw pin-type cover plate 1, and a scraper gripping type stabilizing base 2. The scraper gripping type stabilizing base 2 is fixedly installed above the wellhead rotary table four-jaw pin-type cover plate 1, and a support column 3 is fixedly installed above the scraper gripping type stabilizing base 2. A support cylinder 4 that can move vertically is sleeved on the support column 3. The inner cavity of the support cylinder 4 is threadedly connected to the outer wall of the support column 3. A fixed plate 5 is fixedly installed at the upper end of the support cylinder 4. A horizontally movable arc-shaped seat 6 is symmetrically arranged above the fixed plate 5. The inner wall of the arc-shaped seat 6 is provided with a flexible surface.

[0039] Please see Figure 3 and Figure 4Two sets of guide grooves 7 are symmetrically opened on the upper surface of the fixed plate 5. Guide rods 8 are fixedly installed inside the guide grooves 7. Guide blocks 9 are sleeved on the side walls of the guide rods 8. The guide blocks 9 slide smoothly along the guide rods 8 in the guide grooves 7 on the upper surface of the fixed plate 5. The sliding cooperation between the guide rods 8 and the guide blocks 9 ensures the smoothness of the lateral movement of the arc-shaped seat 6 and avoids deviation. The guide blocks 9 and the guide rods 8 are slidably connected. The bottom surfaces of the arc-shaped seat 6 are fixedly connected to the top surfaces of the guide blocks 9 on both sides. The sliding cooperation between the guide rods 8 and the guide blocks 9 ensures the smoothness of the lateral movement of the arc-shaped seat 6 and avoids deviation. A fixed block 10 is fixedly installed on the outer circumference of the arc-shaped seat 6. A locking rod 11 that can move vertically is installed through the fixed block 10. Multiple sets of locking holes 12 are symmetrically opened on the upper surface of the fixed plate 5. The lower end of the locking rod 11 is engaged with the inside of the locking hole 12. The lower end of the locking rod 11 is inserted into the corresponding locking hole 12 on the fixed plate 5 to achieve precise locking of the arc-shaped seat 6.

[0040] Please see Figure 2 and Figure 4 A locking ring 13 is fixedly installed on the upper side wall of the locking rod 11, and a locking spring 14 is fixedly installed on the bottom surface of the locking ring 13. The lower end of the locking spring 14 is fixedly connected to the upper surface of the fixing block 10. When the locking rods 11 on both sides are released, the rebound force of the locking spring 14 drives the locking rod 11 to move downward through the locking ring 13. The lower end of the locking rod 11 is inserted into the corresponding locking hole 12 on the fixing plate 5. An external thread groove 15 is opened on the outer peripheral surface of the support column 3, and an internal thread groove 16 is opened on the inner wall of the inner cavity of the support cylinder 4. The external thread groove 15 and the internal thread groove 16 are threadedly matched. Since the internal thread groove 16 on the inner wall of the inner cavity of the support cylinder 4 is threadedly matched with the external thread groove 15 on the outer peripheral surface of the support column 3, the support cylinder 4 rises vertically along the support column 3 during rotation. Multiple sets of rotating handles 17 are fixedly installed on the outer peripheral surface of the support cylinder 4. The rotating handles 17 are arranged in a circular array and drive the support cylinder 4 to rotate through the rotating handles 17.

[0041] When the drill bit guide belt buckle device is used in high-frequency operation scenarios, firstly, the four-jaw pin-type cover plate 1 of the wellhead rotary table is fixedly connected to the wellhead rotary table through multiple sets of pins at the bottom to ensure the overall foundation of the device is stable. At the same time, the scraper gripping stable base 2 contacts the protrusions on the surface of the cover plate, and its scraper structure enhances the gripping force to prevent the device from shifting during operation. After the foundation is fixed, the position of the fixing plate 5 is adjusted so that its central axis is on the same vertical axis as the bottom of the pre-installed drill bit to ensure the subsequent drill bit centering accuracy.

[0042] Then, the drill bit to be guided is placed steadily above the fixed plate 5. At this time, the drill bit is located between two sets of symmetrically arranged arc-shaped seats 6. The operator pulls the locking rods 11 on the outer periphery of the two arc-shaped seats 6 upward simultaneously. The locking rods 11 move vertically along the inside of the fixed block 10, which drives the locking ring 13 to stretch the locking spring 14, so that the lower end of the locking rod 11 is disengaged from the locking hole 12 on the upper surface of the fixed plate 5. At this time, the two arc-shaped seats 6 are in the unlocked state. Then, the two arc-shaped seats 6 are pushed inward. The bottom sides of the arc-shaped seats 6 are fixedly connected to the top surface of the guide block 9. The guide block 9 slides smoothly along the guide rod 8 in the guide groove 7 on the upper surface of the fixed plate 5. The sliding cooperation between the guide rod 8 and the guide block 9 ensures the stability of the lateral movement of the arc-shaped seats 6 and avoids deviation.

[0043] When the inner flexible surfaces of the two arc-shaped seats 6 are fully in contact with the outer circumference of the drill bit, stop pushing and release the two locking rods 11. The rebound force of the locking spring 14 drives the locking rod 11 to move downward through the locking ring 13. The lower end of the locking rod 11 is inserted into the corresponding locking hole 12 on the fixed plate 5, so as to achieve precise locking of the arc-shaped seats 6. At this time, the drill bit is firmly clamped by the two sets of arc-shaped seats 6 to prevent it from sliding or tilting during operation.

[0044] After the drill bit is clamped, the operator holds the multiple sets of rotating handles 17 on the outer circumference of the support cylinder 4 and rotates the support cylinder 4 by rotating the handles 17. Since the internal thread groove 16 on the inner wall of the support cylinder 4 is threadedly matched with the external thread groove 15 on the outer circumference of the support column 3, the support cylinder 4 rises vertically along the support column 3 during rotation. At the same time, the clamped drill bit is driven to rotate synchronously and move upward through the fixed plate 5. During the upward movement, the drill bit gradually engages with the upper guide belt buckle structure, and finally completes the guide belt buckle operation.

[0045] This drill bit guide buckle device, through its structured design, achieves mechanization and efficiency in drill bit guide buckle operation, reducing labor intensity and safety risks. Traditional manual rotation of the drill bit by multiple people is time-consuming and labor-intensive, and carries the risk of injury. This device, through the threaded drive structure of the support cylinder 4 and the support column 3, allows a single person to operate the rotating handle 17 to rotate the drill bit, significantly reducing manpower input and improving operational safety. The vertical alignment design of the fixed plate 5 with the bottom of the drill bit, combined with the cooperation of the flexible inner wall surface of the arc seat 6 and the locking mechanism, can adapt to the clamping requirements of drill bits of different sizes. At the same time, the flexible surface avoids scratches on the drill bit surface. The locking spring 14 and the locking hole 12 fit together to ensure clamping stability, prevent drill bit displacement during operation, and improve operational efficiency.

[0046] In summary, this device replaces manual rotation with a mechanized top-rotation design, shortens the lead-in buckle time, and can drive drill bits of different sizes to complete the top-rotation. It is especially suitable for high-frequency operation scenarios and effectively improves the overall efficiency of drilling operations.

[0047] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
