Description

Technical Field

[0001] This utility model relates to the field of drilling exploration technology, and in particular to a drill collar assembly platform. Background Technology

[0002] The drill collar, located at the bottom of the drill string, is a key component of the lower drill string assembly, used to house the power supply module and transmit drilling pressure. In existing technology, the assembly of the drill collar and its internal power supply module is done manually. During assembly, the operator picks up the power supply module, aligns its centerline with the drill collar's centerline, and then forcefully pushes the module into the drill collar, thus completing the assembly.

[0003] However, this assembly method often requires more than five people to operate, and requires constant manual adjustments, which is time-consuming and can easily cause circuit disorder, resulting in low assembly efficiency.

[0004] Therefore, it is necessary to develop a drill collar assembly platform to facilitate the assembly of the power supply module and the drill collar, improve assembly efficiency, and avoid causing circuit disorder. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a drill collar assembly platform, which facilitates the assembly of the power supply module and the drill collar, improves assembly efficiency, and avoids causing circuit disorder.

[0006] To solve the above-mentioned technical problems, this utility model provides a drill collar assembly platform, including a drill collar mounting frame, an assembly base, and a linear drive mechanism. The assembly base is provided with a loading rod, a rotary drive mechanism for driving the loading rod to rotate around its center line, and a yaw drive mechanism for driving the loading rod to rotate horizontally. The loading rod passes horizontally through a power supply module to load the power supply module. The drill collar mounting frame is fixed to the drill collar, the drill collar is horizontally arranged, and the assembly port of the drill collar is opposite to the assembly base. The linear drive mechanism is used to drive the loading rod to extend into or retract from the drill collar.

[0007] As an improvement to the above solution, the loading rod is provided with a positioning structure for engaging and locking with the power supply module.

[0008] As an improvement to the above solution, a slot is provided at the end of the power supply module or the end of the loading rod. The slot is spiral or L-shaped. The outer contour of the cross-section of the loading rod is circular. The power supply module is a sleeve shape adapted to the loading rod.

[0009] As an improvement to the above solution, a sealing ring is provided inside the drill collar, and the power supply module squeezes the inside of the sealing ring when it extends into the drill collar.

[0010] As an improvement to the above solution, the power supply module includes a battery module and a circuit board module. One end of the battery module is engaged with the end face of the circuit board module through a toothed groove, and the other end of the battery module is engaged and locked with the positioning structure of the loading rod.

[0011] As an improvement to the above solution, the drill collar mounting frame is provided with an end positioning seat and a circumferential positioning seat. The end positioning seat and the circumferential positioning seat are located on the extension line of the linear drive mechanism's movement path. The drill collar is supported and circumferentially limited by the circumferential positioning seat, and the end of the drill collar away from the mounting base abuts against the end positioning seat.

[0012] As an improvement to the above solution, the circumferential positioning seat includes a centering clamp and an anti-rotation clamp. The centering clamp supports the drill collar, and the outer wall of the drill collar is provided with a positioning hole. The anti-rotation clamp is provided with a telescopic drive mechanism and a limiting post adapted to the positioning hole. The telescopic drive mechanism is connected to the limiting post to drive the limiting post to engage with the positioning hole.

[0013] As an improvement to the above solution, the assembly base is also provided with a lifting drive mechanism, which is used to drive the loading rod to move vertically.

[0014] As an improvement to the above solution, a first non-contact pose measurement unit is provided above the power supply module, and a second non-contact pose measurement unit is provided above the drill collar. The yaw drive mechanism, the first non-contact pose measurement unit, and the second non-contact pose measurement unit are all connected to the control unit. The yaw drive mechanism drives the loading rod to yaw horizontally so that the center line of the power supply module in the horizontal direction measured by the first non-contact pose measurement unit coincides with the center line of the drill collar in the horizontal direction measured by the second non-contact pose measurement unit.

[0015] As an improvement to the above solution, a third non-contact pose measurement unit is provided on the side of the power supply module, and a fourth non-contact pose measurement unit is provided on the side of the drill collar. The lifting drive mechanism, the third non-contact pose measurement unit, and the fourth non-contact pose measurement unit are all connected to the control unit. The lifting drive mechanism drives the loading rod to move vertically so that the center line of the power supply module in the vertical direction measured by the third non-contact pose measurement unit coincides with the center line of the drill collar in the vertical direction measured by the fourth non-contact pose measurement unit.

[0016] Implementing this utility model has the following beneficial effects:

[0017] This utility model discloses a drill collar assembly platform. The drill collar is horizontally fixed on a drill collar mounting frame, with the assembly port of the drill collar facing the assembly base. A loading rod is provided on the assembly base, horizontally passing through a power supply module to load the power supply module. When the center lines of the loading rod and the drill collar are on the same horizontal plane, a yaw drive mechanism drives the loading rod to rotate horizontally, and a linear drive mechanism drives the loading rod to extend into the drill collar, achieving centering assembly. A rotation drive mechanism drives the loading rod to rotate around its center line, aligning the charging holes on the power supply module and the drill collar. The linear drive mechanism drives the loading rod or removes it from the drill collar to complete the assembly of the drill collar and the power supply module. This drill collar assembly platform uses a loading rod passing through the power supply module to load the power supply module, avoiding circuit disorder. The cooperation of the rotation drive mechanism, yaw drive mechanism, and linear drive mechanism facilitates the assembly of the power supply module and the drill collar, improving assembly efficiency.

[0021] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2 As shown, this utility model discloses an embodiment of a drill collar assembly platform, including a drill collar mounting frame 1, an assembly base 2, and a linear drive mechanism 3. The assembly base 2 is provided with a loading rod 4, a rotation drive mechanism 5 for driving the loading rod 4 to rotate around its center line, and a yaw drive mechanism 6 for driving the loading rod 4 to rotate horizontally. The loading rod 4 horizontally passes through a power supply module 7 to load the power supply module 7. The drill collar mounting frame 1 is fixed to a drill collar 8. The drill collar 8 is horizontally arranged, and the assembly port of the drill collar 8 is opposite to the assembly base 2. The linear drive mechanism 3 is used to drive the loading rod 4 to extend into or retract from the drill collar 8.

[0023] In this embodiment, the drill collar 8 is horizontally fixed on the drill collar mounting frame 1, with the assembly port of the drill collar 8 facing the assembly base 2. The assembly base 2 is provided with a loading rod 4 that horizontally passes through the power supply module 7 to load the power supply module 7. When the center lines of the loading rod 4 and the drill collar 8 are on the same horizontal plane, the loading rod 4 is driven to rotate horizontally by the yaw drive mechanism 6, and the loading rod 4 is driven to extend into the drill collar 8 by the linear drive mechanism 3, which can achieve centering assembly. The loading rod 4 is driven to rotate around its center line by the rotation drive mechanism 5, which can align the charging holes on the power supply module 7 and the drill collar 8. The assembly of the drill collar 8 and the power supply module 7 is completed by the linear drive mechanism 3 driving the loading rod 4 or withdrawing it from the drill collar 8. This drill collar assembly platform uses the loading rod 4 to pass through the power supply module 7 to load the power supply module 7, avoiding circuit disorder. The cooperation of the rotation drive mechanism 5, the yaw drive mechanism 6, and the linear drive mechanism 3 facilitates the assembly of the power supply module 7 and the drill collar 8, and can improve assembly efficiency.

[0024] The loading rod 4 is provided with a positioning structure for engaging and locking with the power supply module 7. In this embodiment, the outer contour of the cross-section of the loading rod 4 is preferably circular, and the power supply module 7 is configured as a sleeve-shaped structure adapted to the loading rod 4. In this way, the power supply module 7 can not only be fitted onto the loading rod 4, but also rotate relative to the loading rod 4 in the unlocked state.

[0025] The specific structure for locking the loading rod 4 and the power supply module 7 is an L-shaped groove (or spiral groove) with an open end and a positioning pin (or protrusion). In this embodiment, the positioning structure on the loading rod 4 is a positioning pin 41, and the power supply module 7 is provided with an L-shaped groove 711 with an open end. When the positioning pin 41 enters the L-shaped groove 711 from the axial direction, and drives the loading rod 4 to rotate around its center line in a first preset direction (clockwise or counterclockwise) by a preset angle, that is, when the loading rod 4 and the power supply module 7 rotate relative to each other to achieve the positioning pin engaging with the L-shaped groove, the loading rod 4 and the power supply module 7 are locked together.

[0026] In this embodiment, a sealing ring is provided inside the drill collar 8. When the power supply module 7 extends into the drill collar 8, it compresses the inside of the sealing ring, that is, the sealing ring can generate a large friction on the power supply module 7. The loading rod 4 inside the drill collar 8 and the power supply module 7 can rotate relative to each other, so that the first charging hole on the power supply module 7 is aligned with the second charging hole on the drill collar 8, or the loading rod 4 is unlocked from the power supply module 7. After the loading rod 4 is unlocked from the power supply module 7, the loading rod 4 inside the drill collar 8 and the power supply module 7 can generate axial displacement relative to each other, so that the power supply module 7 remains inside the drill collar 8, while the loading rod 4 is pulled out from the power supply module 7 and the drill collar 8.

[0027] The power supply module 7 in this embodiment specifically includes a battery module 71 and a circuit board module 72. Both the battery module 71 and the circuit board module 72 adopt a sleeve-shaped frame that is compatible with the loading rod 4.

[0028] One end of the battery module 71 is engaged with the end face of the circuit board module 72 via a toothed groove, and the other end of the battery module 71 is engaged and locked with the positioning structure of the loading rod 4.

[0029] The battery module 71 and the circuit board module 72 can be assembled first and then put together on the loading rod 4. Alternatively, the battery module 71 can be put on the loading rod 4 first, so that the battery module 71 and the positioning structure of the loading rod 4 are engaged and locked, and then the circuit board module 72 can be put on the loading rod 4, so that the circuit board module 72 and the battery module 71 are engaged.

[0030] The drill collar mounting frame 1 is provided with an end positioning seat 9 and a circumferential positioning seat 10. The end positioning seat 9 and the circumferential positioning seat 10 are arranged on the extension line of the motion path of the linear drive mechanism 3. The drill collar 8 is supported and circumferentially limited by the circumferential positioning seat 10, and the end of the drill collar 8 away from the mounting base 2 abuts against the end positioning seat 9.

[0031] The circumferential positioning seat 10 includes a centering clamp 101 and an anti-rotation clamp 102. At least two centering clamps 101 are provided to support the drill collar 8 and prevent displacement. The outer wall of the drill collar 8 has a positioning hole. The anti-rotation clamp 102 has a telescopic drive mechanism and a limiting post adapted to the positioning hole. The telescopic drive mechanism is connected to the limiting post to drive the limiting post to engage with the positioning hole, preventing the drill collar 8 from rotating.

[0032] The mounting base 2 is also provided with a lifting drive mechanism, which is used to drive the loading rod 4 to move vertically.

[0033] like Figure 3As shown, in another embodiment, a first non-contact pose measurement unit 11 is provided above the power supply module 7, and a second non-contact pose measurement unit 12 is provided above the drill collar 8. The yaw drive mechanism 6, the first non-contact pose measurement unit 11, and the second non-contact pose measurement unit 12 are all connected to the control unit 16. The yaw drive mechanism 6 drives the loading rod 4 to yaw horizontally, so that the center line of the power supply module 7 in the horizontal direction measured by the first non-contact pose measurement unit 11 coincides with the center line of the drill collar 8 in the horizontal direction measured by the second non-contact pose measurement unit 12. The control unit 16 controls the yaw drive mechanism 6 to drive the loading rod 4 to yaw horizontally based on the horizontal deviation distance between the center line of the power supply module 7 in the horizontal direction measured by the first non-contact pose measurement unit 11 and the center line of the drill collar 8 in the horizontal direction measured by the second non-contact pose measurement unit 12, thereby reducing the horizontal deviation distance.

[0034] The first non-contact pose measurement unit 11, the second non-contact pose measurement unit 12, and the third non-contact pose measurement unit 13 and the fourth non-contact pose measurement unit 14 described below in this embodiment all use digital precision measurement cameras, which can accurately capture the size and shape of objects with a measurement error of less than 5µm. This makes the battery frame and the center line of the drill collar 8 more coincident, and at the same time can detect whether the positional tolerance meets the requirements. Under the push of the forward moving mechanism, the power supply module 7 can be easily installed into the drill collar 8, avoiding unnecessary scratches.

[0035] The non-contact measurement system also includes a third non-contact pose measurement unit 13 located on the side of the power supply module 7 and a fourth non-contact pose measurement unit 14 located on the side of the drill collar 8. The mounting base 2 is also provided with a lifting drive mechanism, which is used to drive the loading rod 4 to move vertically so that the center line of the power supply module 7 in the vertical direction measured by the third non-contact pose measurement unit 13 coincides with the center line of the drill collar 8 in the vertical direction measured by the fourth non-contact pose measurement unit 14. The control unit 16 reduces the vertical deviation distance based on the vertical deviation distance between the center line of the power supply module 7 in the vertical direction measured by the third non-contact pose measurement unit 13 and the center line of the drill collar 8 in the vertical direction measured by the fourth non-contact pose measurement unit 14.

[0036] In this embodiment, the first non-contact pose measurement unit 11, the second non-contact pose measurement unit 12, the third non-contact pose measurement unit 13, and the fourth non-contact pose measurement unit 14 are all mounted on the test bracket 17.

[0037] When the centerline of the power supply module 7 in the vertical direction, measured by the third non-contact pose measurement unit 13, deviates from the centerline of the drill collar 8 in the vertical direction, measured by the fourth non-contact pose measurement unit 14, the lifting drive mechanism drives the loading rod 4 to move vertically. On the one hand, it no longer requires the centerline of the loading rod 4 to remain on the horizontal plane where the centerline of the drill collar 8 is located, thus reducing the assembly accuracy requirements of the drill collar assembly platform itself and the processing accuracy requirements of the parts. On the other hand, it can adapt to the assembly between drill collars 8 of different diameters and the power supply module 7.

[0038] In this embodiment, both the mounting base 2 and the linear drive mechanism 3 are mounted on the drill collar mounting frame 1, which also has a guide rail 15 for guiding the movement of the mounting base 2. The rotary drive mechanism 5 in this embodiment is a drive motor or a reducer, with its drive end connected to the loading rod 4. The linear drive mechanism 3 uses a motor lead screw assembly, with the lead screw parallel to the guide rail 15, to drive the mounting base 2 to slide reciprocally along the guide rail. The lifting drive mechanism can be a pneumatic cylinder, hydraulic cylinder, electric cylinder, etc., and is mounted on the mounting base 2. The yaw drive mechanism 6 can be a drive motor driving a worm gear or other transmission structure.

[0039] The control unit 16 in this embodiment can be fully automatic or manually controlled using a handheld operator. The drill collar assembly platform of this embodiment achieves automatic alignment and correction, reducing manual operation, avoiding circuit disruptions caused by human contact with the power supply module 7, preventing excessive deflection of the power supply module 7, and preventing scratches on the sealing surface of the drill collar 8 by the power supply module 7. This improves the assembly qualification rate, enables fully automated assembly, reduces labor costs, and increases production efficiency.

[0040] The specific steps for assembling the central control drill collar 8 using the drill collar assembly platform of this embodiment are as follows:

[0041] 1. Place the drill collar 8 into the drill collar mounting frame 1. The drill collar 8 is supported and limited by the centering clamp 101. One end of the drill collar 8 is aligned with the end positioning seat 9. Rotate the drill collar 8 so that the limiting post of the anti-rotation clamp 102 is inserted into the positioning hole of the drill collar 8. Operate the handheld operator to control the yaw drive mechanism 6 to drive the loading rod 4 to rotate horizontally by a set angle (which can be 45°, 60°, etc.). Set the power supply module 7 onto the loading rod 4. The positioning structure on the loading rod 4 engages and locks the power supply module 7.

[0042] 2. Operate the handheld controller to control the yaw drive mechanism 6 to drive the loading rod 4 to rotate horizontally to the initial position. Multiple digital precision measurement cameras non-contactly measure the pose data of the power supply module 7 and the drill collar 8. The yaw drive mechanism 6 drives the loading rod 4 to yaw horizontally. The lifting drive mechanism is used to drive the loading rod 4 to move vertically until the center line of the power supply module 7 measured by the first non-contact pose measurement unit 11 in the horizontal direction coincides with the center line of the drill collar 8 measured by the second non-contact pose measurement unit 12 in the horizontal direction. The center line of the power supply module 7 measured by the third non-contact pose measurement unit 13 in the vertical direction coincides with the center line of the drill collar 8 measured by the fourth non-contact pose measurement unit 14 in the vertical direction.

[0043] 3. Operate the handheld controller to control the linear drive mechanism 3 to drive the mounting base 2 to slide along the guide rail until the power supply module 7 is fed into the drill collar 8;

[0044] 4. Operate the handheld controller to control the rotary drive mechanism 5 to drive the loading rod 4 to rotate around its center line. The loading rod 4 drives the power supply module 7 to rotate, so that the first charging hole on the power supply module 7 is aligned with the second charging hole on the drill collar 8.

[0045] 5. Operate the handheld controller to control the rotary drive mechanism 5 to drive the loading rod 4 to rotate in the opposite direction around its center line, so that the loading rod 4 is unlocked from the power supply module 7. Control the linear drive mechanism 3 to drive the assembly seat 2 to slide along the guide rail until it is pulled away from the power supply module 7 and the drill collar 8, thus completing the entire assembly process.

[0046] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
