Description

Technical Field

[0001] This utility model relates to the field of rib rolling machine technology, specifically a rib rolling machine. Background Technology

[0002] In the field of drilling engineering, drill pipe is a core component, and its surface structure design is crucial to drilling efficiency and stability. With the large-scale development of industries such as mineral resource development and geological exploration, the requirements for drill pipe performance are increasing, especially by adding ribs to the surface of the drill pipe to enhance its friction with rock formations and its ability to remove slag.

[0003] Currently, when adding ribs to the surface of the drill pipe, the rib strips are manually wound onto the drill pipe surface section by section. During this process, the pitch must be repeatedly measured and the winding speed and tension must be manually adjusted to ensure the quality of the rib strip addition.

[0004] However, when adding ribs to the surface of the drill pipe, the winding speed and tension need to be repeatedly measured and manually adjusted during the winding process. This makes it impossible to accurately control the uniformity of the pitch and the tightness of the rib strips, which affects the performance of the drill pipe and reduces production efficiency. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a rib rolling machine to solve the technical problem that the winding speed and tension need to be repeatedly measured and manually adjusted during the rolling process, which makes it impossible to accurately control the pitch uniformity and bonding tightness of the rib strips, thus affecting the performance of the drill rod and reducing production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rib rolling machine, comprising a frame and a control mechanism. A movable block is slidably connected to the top of the frame, and a movable plate is rotatably connected to the top of the movable block. A connecting frame is slidably connected to the top of the frame, and a first motor is mounted on the top of the connecting frame. The output end of the first motor is connected to the bottom of the movable plate via a rotating shaft. A set of fixing blocks is fixedly connected to the top of the movable plate. A first roller is rotatably connected to each adjacent side of the set of fixing blocks. A set of brushes is provided on the surface of each first roller. A second roller is rotatably connected to the top of the movable plate. A second motor is mounted on one side of the frame. The second motor is rotatably connected to a turntable via a shaft, and a three-jaw tool is fixedly connected to one side of the turntable.

[0007] By adopting the above technical solution, when it is necessary to add ribs to the surface of the drill rod, one end of the drill rod can be clamped by a three-jaw tool. According to the actual needs of rolling the rib strip, the first motor is started to drive the movable plate to rotate, thereby adjusting the angle of the fixed block to match the needs of rolling the rib strip. Then, the rib strip is passed through the middle of the fixed block and contacts the drill rod, and it is located below the first roller. At this time, according to the needs, the second motor is started to drive the three-jaw tool to rotate, and the linear motor is started to drive the movable block to move, thus adding rib strips to the surface of the drill rod. Then, the brush on the surface of the first roller can clean the connection between the rib strip and the drill rod, and the second roller can also help guide the rolling path of the rib strip, making the pitch of the rolled rib strip more uniform. At the same time, the first roller and the second roller reduce the metal stress between the drill rod and the rib strip, making the rib strip fit tightly with the drill rod, thereby facilitating the performance of the drill rod. This structure can be adjusted according to the actual needs of adding rib strips to the surface of the drill rod, which can improve the versatility of the device, realize automated rolling, reduce manual intervention, and improve production efficiency.

[0008] The present invention is further configured such that a set of rails is provided at the top of the frame, and a set of linear motors that fit with the rails are provided at the bottom of the movable block, and the linear motors move on the surface of the rails.

[0009] By adopting the above technical solution, the position of the movable block can be adjusted by the movement of the linear motor on the frame, thereby adjusting the movement position according to the actual need to add ribs to the surface of the drill rod, which facilitates the improvement of the versatility of the device.

[0010] The present invention is further configured such that a set of sliding grooves are provided on the top of the frame, and a slider that fits into each sliding groove is slidably connected in each sliding groove. Each slider is fixedly connected to the top of the connecting frame, and the slider is configured as a "T" shaped structure.

[0011] By adopting the above technical solution, the slider and the slide groove are designed so that the connecting frame can slide along the predetermined trajectory at the bottom of the frame. At the same time, the "T"-shaped slider can ensure the stability of the connecting frame's movement, thereby ensuring the stability of the first motor and the movable plate, and guaranteeing the reliability of the rib rolling operation.

[0012] The present invention is further configured such that the top of the frame is provided with a groove that fits with the rotating shaft, and the rotating shaft moves within the groove.

[0013] By adopting the above technical solution, when the linear motor drives the movable block to move at the top of the frame, the rotating shaft can move in the groove, avoiding interference between the two sides and thus affecting the use of the device.

[0014] The present invention is further configured such that a support ring is installed on the top of the movable block.

[0015] By adopting the above technical solution, when ribs are added to the surface of the drill rod, one end of the drill rod can pass through the support ring, thereby supporting the drill rod, increasing the stability of the drill rod, and ensuring the smooth progress of the rib rolling operation.

[0016] The present invention is further configured such that each of the adjacent sides of the set of fixed blocks is fixedly connected to a guide block.

[0017] By adopting the above technical solution, the guide block can guide the rib strip, so that the rib strip maintains the correct path and direction during the rolling process, avoids the rib strip from deviating or twisting, and improves the accuracy and consistency of rib strip rolling.

[0018] The present invention is further configured such that the movable block and the support ring are connected by a plurality of bolts.

[0019] By adopting the above technical solution, the bolt connection method is firm and reliable, which can ensure that the support ring is stably installed on the movable block. This can increase the stability of the drill rod when ribs are added to the surface of the drill rod. At the same time, the bolt connection method facilitates quick installation and disassembly, thereby enabling the maintenance and replacement of the support ring.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention uses a three-jaw clamp to hold one end of the drill rod. A first motor rotates a movable plate to adjust the angle of the fixed block. A rib strip is then passed through the middle of the fixed block and contacts the drill rod, positioned below the first roller. A second motor is then activated to rotate the three-jaw clamp, and a linear motor moves the movable block, thus adding ribs to the surface of the drill rod. A brush on the first roller cleans the connection between the ribs and the drill rod, while the second roller guides the rib strip's winding path, resulting in a more uniform rib pitch. Both the first and second rollers reduce metal stress between the drill rod and the ribs, ensuring a tight fit. This structure can be adjusted to meet the specific needs of adding ribs to the drill rod surface, improving the device's versatility and enabling automated winding, reducing manual intervention and increasing production efficiency.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] Rib rolling machine, such as Figure 1-4 As shown, the device includes a frame 1 and a control mechanism 22. A movable block 4 is slidably connected to the top of the frame 1. A set of rails 2 is provided on the top of the frame 1. A set of linear motors 3 that fit with the rails 2 are provided at the bottom of the movable block 4. The linear motors 3 move on the surface of the rails 2. The position of the movable block 4 can be adjusted by the movement of the linear motors 3 on the surface of the rails 2, which is convenient for adding ribs to the surface of the drill rod. At the same time, the speed of the movable block 4 can be adjusted according to the actual needs during processing, which can increase the versatility of the device.

[0030] Subsequently, a movable plate 5 is rotatably connected to the top of the movable block 4, and a connecting frame 8 is slidably connected to the top of the frame 1. A first motor 7 is installed on the top of the connecting frame 8. The output end of the first motor 7 is connected to the bottom of the movable plate 5 via a rotating shaft 6. A set of fixed blocks 12 are fixedly connected to the top of the movable plate 5. The first motor 7 can be started to drive the connecting frame 8 to rotate via the rotating shaft 6, thereby adjusting the angle of the fixed blocks 12 to match the requirements of the rib strip. The axis of movement of the movable block 4 matches the axis of rotation of the drill rod, avoiding affecting the requirement to add rib strips to the surface of the drill rod. A first roller 13 is rotatably connected to each adjacent side of the set of fixed blocks 12. A set of brushes 14 is provided on the surface of each first roller 13, so that the connection between the rib strip and the drill rod can be cleaned by the brushes 14. The top of the movable plate 5 rotates... A second roller 16 is dynamically connected, which can assist in guiding the rib strip winding path, making the wound rib strip pitch more uniform. At the same time, the first roller 13 and the second roller 16 reduce the metal stress between the drill rod and the rib strip, making the rib strip fit tightly with the drill rod. A second motor 20 is installed on one side of the frame 1. The second motor 20 is rotatably connected to a turntable 21 via a shaft, and a three-jaw fixture 19 is fixedly connected to one side of the turntable 21. The three-jaw fixture 19 can clamp one end of the drill rod. Then, the second motor 20 is started to drive the three-jaw fixture 19 and the drill rod to drill a hole, thereby adding rib strips to the surface of the drill rod. This structure can be adjusted according to the actual needs of adding rib strips to the surface of the drill rod, which can improve the versatility of the device, realize automated winding, reduce manual intervention, and improve production efficiency.

[0031] A set of sliding grooves 10 is provided at the bottom of the frame 1. Each sliding groove 10 is slidably connected to a slider 11 that matches the sliding groove 10. Each slider 11 is fixedly connected to the top of the connecting frame 8. The design of the sliding grooves 10 and sliders 11 allows the connecting frame 8 to move along a predetermined trajectory on the top of the frame 1. The sliders 11 are designed with a "T" shape to ensure the stability of the movement of the connecting frame 8, thereby ensuring the stability of the positions of the first motor 7 and the movable plate 5, and ensuring the reliability of the rib rolling operation. At the same time, a groove 9 that matches the rotating shaft 6 is provided on the top of the frame 1. The rotating shaft 6 moves within the groove 9. When the linear motor 3 drives the movable block 4 to move, the rotating shaft 6 can move within the groove 9, avoiding motion interference that would affect the use of the device.

[0032] Furthermore, guide blocks 15 are fixedly connected to each side of a set of fixed blocks 12. The guide blocks 15 can guide the rib strip, so that the rib strip maintains the correct path and direction during the rolling process, avoids the rib strip from deviating or twisting, and improves the accuracy and consistency of rib strip rolling.

[0033] Meanwhile, a support ring 17 is installed on the top of the movable block 4. Therefore, when ribs are added to the surface of the drill rod, one end of the drill rod can pass through the support ring 17, thereby supporting the drill rod and increasing its stability. This ensures the smooth progress of the rib rolling operation. The movable block 4 and the support ring 17 are connected by multiple bolts 18. The bolt connection method facilitates quick installation and disassembly, thereby enabling the maintenance and replacement of the support ring 17.

[0034] Therefore, during the use of this device, the control mechanism 22 can be used to control the first motor 7, the second motor 20 and the linear motor 3, so as to adjust their rotation speed and moving speed according to the actual needs of rolling the rib strip, and to make the device easier to use. At the same time, the linear motor 3, the three-jaw tool 19 and other structures in this embodiment are existing technologies and are technical means that are easily known to those skilled in the art.
