Detailed implementation manner
[0019] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, describe in detail the specific implementation manner, structure, features and their effects of the present invention.
[0020] Please refer to Figures 1-8 As shown, the present invention provides a docking device for a logging instrument, including a tower 1 erected in the logging area. Outside the tower 1, an operation platform 2 and an operation platform 3 are successively arranged from top to bottom. Inside the operation platform 3, a traction roller 4 for winding the cable is installed. Inside the operation platform 2, there is a support plate 7 arranged vertically and reinforced by a reinforcing rod. On the surface of the support plate 7, a lower bearing plate 9 that does not move simultaneously and supports the upper bearing plate 8 of the logging instrument module one and the logging instrument module two is limited to slide. The lower bearing plate 9 is arranged below the upper bearing plate 8. Above the upper bearing plate 8, a clamping unit 20 for fixing the logging instrument module one slides. And below the upper bearing plate 8, there is a clamping unit 3 16 that is vertically collinear with the logging instrument module one and fixes the logging instrument module two. On one side of the operation platform 2 away from the support plate 7, a segmented docking assembly for transferring the logging instrument modules to the clamping unit 20 and the clamping unit 3 16 respectively is installed. At the end of the cable, there is a joint 17. The outside of the joint 17 is rotatably connected with a chuck seat 18, and the outside of the chuck seat 18 is a regular hexagon. On one side above the support plate 7, a connecting plate 27 is installed. Below the connecting plate 27, an automatic tightening assembly for threadedly sleeving the chuck seat 18 on the end of the logging instrument module is installed. The automatic tightening assembly includes a fixing piece 26 and a fitting piece 19 that cooperate with the chuck seat 18. Tooth blocks 22 are provided on the outer surfaces of the fixing piece 26 and the fitting piece 19. On one side of the fixing piece 26, a rotating frame 25 is installed. At the end of the rotating frame 25, a drive gear 23 that meshes with the tooth block 22 is rotatably installed. At the operation console 2, each module of the logging instrument is arranged in sequence. First, the logging instrument module 1 is installed. In the assembled state, the lower carrier plate 9 slides open to a separated state, while the upper carrier plate 8 above is in a supporting state. The logging instrument module 1 is transferred by the segmented docking assembly. The bottom of the logging instrument module 1 is supported by the upper carrier plate 8 to complete the positioning and placement. Then, the outside of the logging instrument module 1 is fixed by the clamping unit two 20. Immediately afterwards, the logging instrument module 2 is transferred by the segmented docking assembly. When transferring here, the height of the segmented docking assembly changes (decreases). Correspondingly, the upper carrier plate 8 automatically slides out of the supporting position, while the lower carrier plate 9 is in a supporting state. Since the logging instrument module 1 has been fixed by the clamping unit two 20, it will not fall. Then, the logging instrument module 2 is vertically placed on the lower carrier plate 9 and fixed by the clamping unit three 16. At this time, the logging instrument module 1 and the logging instrument module 2 are on the same vertical line, which is convenient for their docking and assembly. Then, by moving the clamping unit two 20 downward in the vertical direction, the logging instrument module 1 and the logging instrument module 2 are quickly plugged together. After the plugging is completed, by moving the clamping unit two 20 upward in the vertical direction, the whole logging instrument moves upward, and the logging instrument module 1 among them is plugged into the joint 17. During the process of plugging the joint 17, the chuck seat 18 enters into the fitting 19 and the fixing member 26. The fitting 19 and the fixing member 26 jointly restrict the chuck seat 18. Then, the driving gear 23 drives the tooth block 22, so that the chuck seat 18 fitted by the fitting 19 and the fixing member 26 rotates. At this time, the chuck seat 18 is threadedly sleeved on the end of the logging instrument module 1 to achieve a firm connection. Through the above process, high-precision automatic docking and assembly operations between the logging instrument modules and with the upper joint 17 can be realized, significantly improving the assembly efficiency and docking stability, and reducing the manual intervention and error risk. It should be noted that after all the modules are connected, power-on testing, communication testing, and data sampling inspection are carried out to ensure complete connection and continuous signal.
[0021] Refer to Figure 5 As shown, the automatic tightening assembly further includes electromagnets 21 embedded in the two side edges of the fixing member 26. The rod bodies connected to the armatures in each electromagnet 21 are fixed to the two side edges of the fitting 19. A fixed seat is provided on the support plate 7, and a rotating unit 24 for driving the rotating frame 25 to rotate is installed on the fixed seat. The rotating unit 24 is a rotating motor. The bottom of the connecting plate 27 is provided with a rail groove 28 for the limiting sliding of the fitting 19 and the fixing member 26. One side of the rail groove 28 is provided with a horizontal rail 29 for the limiting sliding when the fitting 19 is opened, which is used to limit the sliding range of the fitting 19 in the "open state" to prevent excessive opening or misalignment. When powered on, the electromagnet 21 attracts the armature, driving the fitting 19 to move inward along the horizontal rail 29 until it fits with the chuck seat 18, completing the restriction and covering of the chuck seat 18. Through the rotation of the rotation unit 24, the driving gear 23 on the rotating frame 25 meshes with the tooth block 22, completing the process of screwing and locking the thread of the chuck seat 18. The fitting 19 moves inward along the horizontal rail 29 to a position communicating with the rail groove 28. Through the rotation of the fitting 19 and the fixing member 26, since the fitting 19 is embedded in the rail groove 28 at this time, its rotational movement is restricted by the rail groove 28 and completes an orderly rotation under its guidance, thereby driving the chuck seat 18 to thread-engage with the end of the logging module one and complete the locking action.
[0022] Refer to Figure 3 As shown, the segmented docking assembly includes a lifting unit one 12. The pushing end of the lifting unit one 12 is provided with a flipping unit 13. The flipping unit 13 includes a support bottom plate and a flipping plate rotatably connected to the support bottom plate. The upper end surface of the flipping plate is provided with a lifting unit two 14. The pushing end of the lifting unit two 14 is provided with a clamping unit one 15 for fixing the logging instrument module one. The lifting unit one 12 is used to control the vertical height of the overall flipping structure and adjust the attitude of the logging module after the height is determined. The flipping unit 13 adopts the existing method of driving the transmission rod by a lead screw to complete the attitude adjustment of the logging instrument module from horizontal to vertical.
[0023] The lifting unit two 14 is used to accurately place the logging instrument module into the designated positions of the upper bearing plate 8 and the lower bearing plate 9 after the flipping angle adjustment is completed.
[0024] Refer to Figure 3 As shown, inside the operation table one 2, there is a drive shaft rod 10 driven by a motor. Two eccentric wheels 11 are sleeved outside the drive shaft rod 10. The two eccentric wheels 11 are arranged at an interval of 180 degrees, and the eccentric wheels 11 are in contact with the upper bearing plate 8 and the lower bearing plate 9. Elastic members are sleeved outside both the upper bearing plate 8 and the lower bearing plate 9. The ends of the elastic members are fixed to the side surface of the support plate 7. When the motor drives the drive shaft rod 10 to rotate, the two groups of eccentric wheels 11 generate alternating radial thrusts, thereby driving the upper bearing plate 8 and the lower bearing plate 9 to slide alternately open or closed on the support plate 7 to adapt to the alternating support of the logging instrument module.
[0025] Refer to Figure 2 、 Figure 7 and Figure 8 As shown, a cleaning box 6 for removing dirt from the surface of the cable is provided in the second operating table 3, and a traction roller 4 is installed on the bottom surface of the top of the tower 1; The cleaning box 6 is provided with a primary cleaning chamber and a secondary cleaning chamber. After secondary cleaning, it is dried and sent out by the annular air duct, and is wound by the traction roller 4 after being in guiding contact with the guide wheel 5; Both the primary cleaning chamber and the secondary cleaning chamber are provided with sliding frames 31 that reciprocate in the vertical direction. The cable vertically passes through the opening of the sliding frame 31. One inner wall surface of the sliding frame 31 is installed with a finger cylinder 33, and both driving ends of the finger cylinder 33 are rotatably connected with fitting rollers 32 that rollingly contact the surface of the cable; Electric push rods 30 for pushing the corresponding sliding frames 31 to move synchronously are installed in both the primary cleaning chamber and the secondary cleaning chamber. A guide frame 34 is installed at the end of the sliding frame 31, and the guide frame 34 is slidably fitted with the inner walls of the primary cleaning chamber and the secondary cleaning chamber; There is an alkaline degreasing agent in the primary cleaning chamber, which is used to preliminarily remove oil stains, mud and heavy pollution attachments on the surface of the cable; When the cable is retracted, in order to remove attachments such as well fluid, mud, and oil stains, it passes through the primary cleaning chamber and the secondary cleaning chamber in sequence, and passes through the center of the openings of the two sliding frames 31. Then, the finger cylinder 33 drives the two fitting rollers 32 to approach each other, so that the fitting rollers 32 cover the outer surface of the cable, and the electric push rod 30 drives the sliding frame 31 to reciprocate in the vertical direction, so that the fitting rollers 32 perform dynamic rolling brushing on the surface of the cable. In one movement, through the setting of the guide frame 34, the deviation of the sliding path is restricted, the stability is enhanced, the cleaning of the two cleaning chambers is completed, and the rough cleaning is carried out in the primary cleaning chamber, In the primary cleaning chamber, under the action of the alkaline degreasing agent medium, the fitting roller 32 cooperates with the up and down movement to perform rough cleaning and degreasing and dirt removal; In the secondary cleaning chamber, the fitting roller 32 further finely cleans the residual oil film and fine particles in the neutral cleaning solution, improving the cleanliness of the cable surface. The two sliding frames 31 and the fitting rollers 32 cooperate to complete the whole process cleaning task of the cable, greatly improving its cleaning uniformity and surface cleanliness.
[0026] When the present invention is in use, the logging instrument module is positioned on the upper bearing plate 8 and the lower bearing plate 9 at different heights through the segmented docking component, and is fixed by the corresponding clamping unit two 20 and the clamping unit three 16. At this time, the logging instrument module one and the logging instrument module two are on the same vertical line, which is convenient for their docking and assembly. Then, by the downward movement of the clamping unit two 20 in the vertical direction, the logging instrument module one and the logging instrument module two are quickly inserted. By using the upward movement of the clamping unit two 20 in the vertical direction, the whole logging instrument moves upward, and the logging instrument module one therein is inserted into the joint 17. The chuck seat 18 enters into the fitting 19 and the fixing member 26, and the fitting 19 and the fixing member 26 jointly restrict the chuck seat 18. Then, the driving gear 23 drives the tooth block 22, so that the chuck seat 18 fitted by the fitting 19 and the fixing member 26 rotates. At this time, the chuck seat 18 is threadedly sleeved on the end of the logging instrument module one to achieve a firm connection. Through the above process, the high-precision automatic docking and assembly operation between the logging instrument modules and with the upper joint 17 can be realized, the assembly efficiency and the docking stability are significantly improved, and the manual intervention and the error risk are reduced; The provided segmented docking component is used to adjust the height and the flipping angle of the logging instrument module. In cooperation with the lifting unit two 14, the logging instrument module is accurately placed at the designated positions of the upper bearing plate 8 and the lower bearing plate 9, improving the alignment accuracy; Through the different movements of the upper bearing plate 8 and the lower bearing plate 9, it is convenient to place the logging instrument module in segments successively. When the upper bearing plate 8 withdraws from the supporting position and the lower bearing plate 9 below positions and places the logging instrument module, it is convenient for its alignment and assembly; By providing a primary cleaning chamber and a secondary cleaning chamber, the finger cylinder 33 drives the two fitting rollers 32 to approach each other, so that the fitting rollers 32 cover the outer surface of the cable. The electric push rod 30 drives the sliding frame 31 to reciprocate in the vertical direction. Under the action of the alkaline degreasing agent medium in the primary cleaning chamber, the fitting rollers 32 are combined with the up and down movement to perform rough cleaning and degreasing and dirt removal. The fitting rollers 32 are in the neutral cleaning liquid in the secondary cleaning chamber to further finely wash the residual oil film and fine particles, improving the cleanliness of the cable surface. The two sliding frames 31 and the fitting rollers 32 cooperate to complete the whole process cleaning task of the cable, greatly improving its cleaning uniformity and surface cleanliness.
