Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a feeding device for male and female drill pipe joints. Background Technology

[0002] In existing technologies, male and female drill pipe joints are key components used to connect drill pipes in oil drilling and geological exploration. Their core feature is that reliable connection and load transfer between drill pipes are achieved through the pairing of male and female threads.

[0003] Male and female drill pipe joints are mostly made of D-grade to S-grade alloy steel or modified titanium alloy to ensure high yield strength and wear resistance. Therefore, although the drill pipe joints themselves are not large in size, they are quite heavy. During the production of male and female drill pipe joints, the male and female joints need to be pre-grinded to simulate downhole operations and ensure the effectiveness of the joints. Simultaneously, the pre-grinded male and female drill pipe joints undergo marking and matching processes.

[0004] In actual operation, the male and female drill pipe joints need to be moved manually by overhead crane. After loading, the surface of the drill pipe joints needs to be manually inspected for defects. The method of directly loading by hoisting and placing the joints will result in some structures not being able to be observed. Observing during hoisting also carries a significant risk. Therefore, there is an urgent need for a special loading mechanism to assist in loading the male and female drill pipe joints. Utility Model Content

[0011] Separation structure one is set at one end below the top platform and close to the rotating platform. The main body is set as a limiting rotating shaft. Multiple limiting arms are fixedly installed at equal intervals on the outer wall of the limiting rotating shaft. Multiple arm fitting grooves adapted to the limiting arms are opened at equal intervals on the upper surface of the top platform.

[0012] The slide structure is mainly configured as an installation slide, which is fixedly installed inside the material storage platform. A connecting square tube is slidably installed inside the installation slide, and the top of the connecting square tube is fixedly connected to a material loading slide that is flush with the top plate of the material storage platform.

[0013] As a further improvement of this utility model: a lifting connecting plate is fixedly installed on the top of the lifting cylinder, and a protective rubber pad is fixedly connected to the top of the lifting connecting plate.

[0014] As a further improvement of this utility model: protective sliding rods are fixedly installed at the bottom of both ends of the lifting connecting plate, and sliding rod limiting cylinders are slidably sleeved on the outer wall of the protective sliding rods.

[0015] As a further embodiment of this utility model: a material unloading slide is provided on one side of the mounting base, and a drive motor is provided on the front of the material unloading slide. The drive motor is connected to one of the mounting shafts via a sprocket and chain.

[0017] As a further improvement of this utility model: a rotating motor is provided on one side of the mounting base, and a drive gear that meshes with an external gear ring is fixedly installed at the top of the output shaft of the rotating motor.

[0018] As a further embodiment of this utility model: a positioning mounting bracket is fixedly installed at one end of the mounting slide, and a telescopic cylinder is fixedly installed inside the positioning mounting bracket, with the telescopic end of the telescopic cylinder being fixedly connected to the connecting square tube.

[0019] As a further embodiment of this utility model: a mounting ring is fixedly installed at the front end of the limiting rotating shaft, a transmission cross arm is welded to one side of the mounting ring, a pin sleeve is rotatably connected to the end of the transmission cross arm, an electric telescopic rod is fixedly installed on one side of the pin sleeve, and a positioning mounting seat is rotatably installed at the tail end of the electric telescopic rod.

The tangential design of the bearing roller and the feeding slide reduces the kinetic energy of the workpiece rolling and minimizes the risk of collision.

[0025] 3. The male and female drill pipe joint feeding device controls the bearing roller to rotate at low speed through a drive motor, which facilitates worker handling and avoids safety hazards or processing errors caused by high-speed rolling of the workpiece; the rotating platform adopts an external gear ring driven by a servo motor and a drive gear transmission, in conjunction with a reducer, to ensure the accuracy and stability of the bearing turntable rotating 90 degrees counterclockwise and clockwise, and reliable repeatability.

[0026] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0036] A male and female drill pipe joint feeding device, such as Figures 1 to 7 As shown, it includes: a rotating platform for carrying the male and female drill pipe connector 11, a material storage assembly for continuously feeding the male and female drill pipe connector 11, a slide structure for connecting the rotating platform and the material storage assembly, a separation structure for controlling the feeding frequency of the material storage assembly, a lifting assembly for transferring the male and female drill pipe connector 11 from the rotating platform, and a controller for controlling the operation of the overall device.

[0037] The main body of the rotating platform is a bearing turntable 5. The bottom end of the bearing turntable 5 is rotatably mounted with a mounting base 1, and an external gear ring 6 is fixedly mounted on the outer wall of the bearing turntable 5. A motor bracket 2 is fixedly mounted on one side of the mounting base 1. A rotating motor 3 is fixedly mounted inside the motor bracket 2. A drive gear 4 is fixedly mounted on the top of the output shaft of the rotating motor 3. The drive gear 4 meshes with the external gear ring 6.

[0038] The rotating motor 3 is set as a servo motor and is directly controlled by the controller. The rotating motor 3 itself is equipped with a reducer to ensure the stability of the transmission between the drive gear 4 and the external gear ring 6. The controller controls the load-bearing turntable 5 to rotate counterclockwise by 90 degrees and then clockwise by 90 degrees to return to the initial state, so that the load-bearing turntable 5 completes one action.

[0039] A mounting base 7 is fixedly installed at the top center of the load-bearing turntable 5. Both ends of the mounting base 7 are fixedly installed with end limiting plates 24. Two mounting shafts 25 are symmetrically installed at the top between the two end limiting plates 24. A load-bearing roller 26 is fixedly sleeved on the outer wall of the mounting shaft 25.

[0040] The male and female drill pipe connectors 11, which require post-processing (steps that require long-term manual intervention, such as chip removal and grinding) and maintenance (such as rust prevention spraying), are placed on two bearing rollers 26 and await manual processing.

[0041] A feeding slide 8 is provided on the side of the mounting base 7 near the rotating motor 3. The bottom end of the feeding slide 8 is fixedly installed on the top of the bearing turntable 5, and the top surface is set as an inclined surface. The angle between the inclined surface and the horizontal plane is set to five degrees, and the inclined surface is tangent to the outer wall of the adjacent bearing roller 26, so that the male and female drill rod connector 11 can roll out smoothly without generating a large amount of kinetic energy.

[0042] The front of the unloading slide 8 is provided with a motor base 9, which is fixedly installed on the top of the bearing turntable 5. The top of the motor base 9 drives the motor 10, which is connected to the adjacent mounting shaft 25 through a sprocket and chain.

[0043] The drive motor 10 has its own deceleration and is directly controlled by the controller. Under the control of the controller, the drive motor 10 controls the corresponding mounting shaft 25 to rotate at low speed, which in turn drives the male and female drill pipe connector 11 to rotate through the bearing roller 26, making it easier for workers to process the male and female drill pipe connector 11.

[0044] The main body of the lifting assembly is a lifting cylinder 27, which is fixedly installed inside the mounting base 7. A lifting connecting plate 28 is fixedly installed on the top of the lifting cylinder 27, and a protective rubber pad 29 is fixedly connected to the top of the lifting connecting plate 28.

[0045] The lifting connecting plate 28 is located below the two bearing rollers 26, without contacting the two bearing rollers 26, and close to the bearing roller 26 that is away from the unloading slide table 8.

[0046] The lifting cylinder 27 is directly controlled by the controller and is existing technology, so its structure will not be described in detail in this application; the lifting cylinder 27 extends and directly lifts the male and female drill rod connector 11 through the protective rubber pad 29, so that the male and female drill rod connector 11 rolls down to the material slide table 8.

[0047] Protective sliding rods 30 are fixedly installed at both ends of the lifting connecting plate 28. A sliding rod limiting cylinder 31 is slidably sleeved on the outer wall of the protective sliding rod 30. A fixed support arm is integrally formed at the bottom end of the sliding rod limiting cylinder 31. The fixed support arm is fixed to the lifting cylinder 27 and fixedly connected to the mounting base 7, thereby improving the stability of the lifting connecting plate 28 during the process of lifting the male and female drill pipe connector 11.

[0048] like Figure 7 As shown, a protective shell 44 can also be installed on the rotating platform. The protective shell 44 is fixedly connected to the mounting base 7 and rotates synchronously with the mounting base 7 to protect the rotating platform and improve the overall aesthetics of the device.

[0049] The main body of the material storage assembly is a feeding storage platform 13. The angle between the top plate of the feeding storage platform 13 and the horizontal plane is set to five degrees, and the end closer to the rotating platform is set as the lower end. A chamfer is provided on the upper part of the bottom of the top plate to ensure the stability of the male and female drill rod connector 11 during feeding. A support base 12 is fixedly installed at the bottom of the feeding storage platform 13.

[0050] The main body of the slide structure is a mounting slide 21, which is fixedly installed inside the material storage platform 13 near the rotating platform. A connecting square tube 32 is slidably installed inside the mounting slide 21, and a material feeding slide 33 with the same plane as the top plate of the material storage platform 13 is fixedly connected to the top of the connecting square tube 32.

[0051] The connecting square tube 32 slides horizontally inside the mounting slide 21, causing the feeding slide 33 to move synchronously; as Figure 1 As shown, when the upper surface of the feeding slide 33 is in contact with the lower surface of the top plate of the feeding storage platform 13, the upper surface of the feeding slide 33 is tangent to the outer wall of the adjacent bearing roller 26, so that the male and female drill rod connector 11 can smoothly roll down between the two bearing rollers 26 at a lower speed.

[0052] A positioning mounting bracket 22 is fixedly installed at the end of the mounting carriage 21 away from the rotating platform. A telescopic cylinder 23 is fixedly installed inside the positioning mounting bracket 22. A connecting partition is welded inside the end of the connecting square tube 32 away from the rotating platform. The telescopic end of the telescopic cylinder 23 is fixedly connected to the connecting partition.

[0053] The telescopic cylinder 23 is directly controlled by the controller and is used to control the position of the feeding slide 33. After the male and female drill rod connector 11 completes the feeding work, the controller controls the feeding slide 33 to retract into the feeding storage platform 13 through the telescopic cylinder 23 to avoid interfering with the operation of the rotating platform.

[0054] The first separation structure is located at the end of the top platform near the rotating platform. The main body is a limiting shaft 34. The top of the feeding slide 33 is lower than the bottom of the limiting shaft 34 to prevent the limiting shaft 34 from obstructing the feeding slide 33 during the retraction process. Multiple limiting arms 35 are fixedly installed at equal intervals on the outer wall of the limiting shaft 34. The top of the limiting arms 35 is used to block the male and female drill rod connectors 11. The upper surface of the top platform is provided with multiple arm fitting grooves 43 that are adapted to the limiting arms 35, so that the limiting arms 35 can swing with the limiting shaft 34.

[0055] Both ends of the limiting shaft 34 pass through the main body of the feeding storage platform 13 and extend outward. The extended end is rotatably mounted with a mounting bearing seat 36, which is fixed to the feeding storage platform 13. The front end of the limiting shaft 34 is fixedly mounted with a mounting retaining ring 37. A transmission cross arm 38 is welded to one side of the mounting retaining ring 37. A positioning pin 39 is fixedly connected to the front of the end of the transmission cross arm 38 away from the mounting retaining ring 37. A pin sleeve 40 is rotatably sleeved on the outer wall of the positioning pin 39. An electric telescopic rod 41 is fixedly mounted on one side of the pin sleeve 40. A positioning pin 2 is rotatably mounted on the tail end of the electric telescopic rod 41. A positioning mounting seat 42 is welded to the tail end of the positioning pin 2. The positioning mounting seat 42 is fixedly mounted on the front of the feeding storage platform 13.

[0056] like Figure 1 As shown, at this time, the side wall of the limiting arm 35 is tangent to the outer wall of the male and female drill pipe connector 11, and the plane of this side wall is perpendicular to the upper surface of the top plate. At this time, the electric telescopic rod 41 is in its maximum extension state. When the electric telescopic rod 41 retracts, the transmission cross arm 38 drives the limiting shaft 34 to rotate counterclockwise through the mounting ring 37 until the electric telescopic rod 41 is fully retracted. The side wall of the limiting arm 35 that is in contact with the male and female drill pipe connector 11 is completely inserted into the arm fitting groove 43. At this time, the axis of the electric telescopic rod 41 is below the axis of the limiting shaft 34, so that when the electric telescopic rod 41 extends again, the limiting shaft 34 can rotate clockwise smoothly.

[0057] The electric telescopic rod 41 is controlled by a controller, and its structure and control method will not be described in detail. During the movement of the aforementioned separation structure one, the male and female drill rod connectors 11, which are directly blocked by the limiting arm 35, can roll over the area of ​​the arm fitting groove 43 within two seconds under their own weight and the slope of the top platform, and then smoothly roll down onto the rotating platform. The subsequent male and female drill rod connectors 11 will also roll down under their own interaction force and gravitational acceleration. However, due to the time difference of rolling and the speed difference caused by gravitational acceleration, a displacement difference will occur between the first and second rolling male and female drill rod connectors 11. When the first rolling male and female drill rod connector 11 rolls over the area of ​​the arm fitting groove 43, the electric telescopic rod 41 quickly extends and retracts, causing the limiting arm 35 to return to its initial state (e.g., Figure 1 As shown), it again presses against the male and female drill pipe connector 11 that has just started rolling, and limits the subsequent male and female drill pipe connector 11. Since the speed of the male and female drill pipe connector 11 that has just started rolling is small, the impact force on the limit arm 35 is small and will not affect the structural stability of the separation structure one.

[0058] Separation structure one can be replaced by separation structure two. The main body of separation structure two is set as two mounting arms 14. The two mounting arms 14 are symmetrically installed on the front and back sides of the material storage platform 13 near the end of the rotating platform. A top mounting frame 15 is fixedly installed on the top between the two mounting arms 14. Mounting clips 16 are welded on both sides of the top mounting frame 15. A lifting cylinder 17 is fixedly installed inside the mounting clip 16. The telescopic end of the lifting cylinder 17 passes through the top mounting frame 15 and extends downward.

[0059] A limit baffle 20 is fixedly installed at the bottom of the telescopic end of the lifting cylinder 17. Two limit baffles 20 are respectively located on both sides of the same male and female drill rod connector 11. Limit slide rods 19 are fixedly installed at both ends of the top of the limit baffles 20. The outer wall of the limit slide rod 19 is slidably sleeved with a limit slide cylinder 18. The limit slide cylinder 18 is welded to the top mounting bracket 15.

[0060] like Figure 3 As shown, the separation structure is in its initial state at this time. The limiting baffle 20 near the rotating platform abuts against the male and female drill rod connector 11 that is about to be unloaded, and another limiting baffle 20 abuts against the next male and female drill rod connector 11. The lifting cylinder 17 is controlled by the controller, and its structure and control method will not be described in detail.

[0061] The lifting cylinder 17 controls the rise of the limiting baffle 20 near the rotating platform in the separation structure, causing the male and female drill rod connector 11 between the two limiting baffles 20 to roll down at low speed under its own weight, smoothly rolling down along the feeding slide 33 to the top of the two bearing rollers 26; then the feeding slide 33 is controlled to retract into the feeding storage platform 13; next, the rising limiting baffle 20 is lowered to its initial state, and the other limiting baffle 20 rises, causing the male and female drill rod connector 11 on the feeding storage platform 13 to roll down, forming a... Figure 3 The state shown is then adjusted so that the limiting baffle 20 falls, and the separation structure 2 returns to its initial state.

[0062] Working principle:

[0063] Please refer to Figures 1 to 7 Assemble the device as shown in the figure;

[0064] When this device is in operation, the controller first controls the feeding slide 33 to fit against the top plate of the feeding storage platform 13 via the telescopic cylinder 23. Then, it controls the electric telescopic rod 41 to retract, and the transmission arm 38 drives the limiting shaft 34 to rotate counterclockwise via the mounting ring 37. When the electric telescopic rod 41 is fully retracted, the male and female drill rod connector 11, which is directly blocked by the limiting arm 35, rolls over the area of ​​the arm mating groove 43 within two seconds and then smoothly rolls down onto the rotating platform. Then, the electric telescopic rod 41 is extended again, and the limiting shaft 34 rotates clockwise, so that the limiting arm 35 returns to its initial state (e.g., ...). Figure 1 As shown), the controller again presses against the male and female drill rod connector 11 that has just started rolling, limiting the subsequent male and female drill rod connector 11; the controller then controls the drive motor 10 to drive the male and female drill rod connector 11 to rotate, and the worker processes the male and female drill rod connector 11. After processing, the controller controls the rotating motor 3 to drive the bearing turntable 5 to rotate counterclockwise by 90 degrees, and then controls the lifting cylinder 27 to extend, directly lifting the male and female drill rod connector 11 through the protective rubber pad 29, so that the male and female drill rod connector 11 rolls down to the material slide table 8 and slides into the storage box (not shown, used to store the processed male and female drill rod connector 11), and finally rotates clockwise by 90 degrees to return to the initial state.

[0065] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
