Description

Technical Field

[0001] This utility model relates to the field of pipe processing and surface treatment technology, and in particular to an inner wall rust removal device for composite pipe production. Background Technology

[0002] Composite pipes, as a high-performance fluid transport material, are widely used in petroleum, chemical, and municipal construction. During the manufacturing process of composite pipes, to ensure the bonding strength between the metal layer and the protective layer, or to meet the cleanliness requirements of subsequent fluid transport, the inner wall of the metal pipe must undergo rigorous rust removal and grinding. Residual rust or oxide scale on the inner wall will directly affect the corrosion resistance and service life of the composite pipe.

[0003] Currently, most existing internal rust removal devices use a rotary drive method, that is, a motor drives a long shaft, and a wire brush or abrasive wheel is fixedly installed at the end of the shaft to extend into the pipe for grinding. However, this traditional structure has a significant technical drawback, that is, the working diameter of its rust removal end is usually fixed, or can only be adjusted within a very small range by bolts.

[0004] When a production line needs to process composite pipes of different diameters, or when the inner diameter of the same pipe varies slightly due to manufacturing tolerances, this type of fixed rust removal head becomes inadequate. If the diameter of the rust removal head is smaller than the inner diameter of the pipe, it cannot effectively contact the pipe wall, resulting in incomplete rust removal; if the diameter of the rust removal head is forced to match or slightly larger than the inner diameter of the pipe, it is prone to jamming during pipe insertion or causing excessive cutting damage to the pipe wall. To solve this problem, operators often need to prepare multiple sets of rust removal equipment of different specifications, or spend a lot of time disassembling the equipment and replacing different sized brush heads when changing pipe diameters. This not only increases the purchase cost of equipment, but also seriously reduces the operating efficiency of the production line.

[0005] Therefore, this utility model proposes an inner wall rust removal device for composite pipe production to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems that existing pipe rust removal equipment usually adopts a fixed diameter grinding head structure, which cannot flexibly adapt to the changes in the inner diameter of composite pipes of different specifications, resulting in frequent shutdowns to disassemble and replace the entire set of equipment when carrying out multi-specification production tasks, as well as cumbersome maintenance after grinding head wear, poor equipment versatility and low operating efficiency, this utility model aims to provide an improved composite pipe production inner wall rust removal device with an adaptive diameter change through a linkage mechanism and convenient and quick maintenance.

[0007] This utility model provides an inner wall rust removal device for composite pipe production, including: a base, a support base, a column, a handwheel, a drive motor, an adaptive component, a rust removal component, a turntable, a connecting rod, a driven wheel, and a driving wheel; the drive motor is installed above the base, the support base provides load-bearing support, the turntable is rotatably mounted on the support base, and the column is located above the turntable and connected to the adaptive component.

[0008] The adaptive component includes a base plate, a sliding plate, an outer plate, a support base, a linkage arm, a drive arm, fixing bolts, a vertical rod, and a fixing plate. The base plate is installed on the top of the column, the support base is fixed to the base plate by the vertical rod, and the bottom of the linkage arm is connected to the support base. The connecting rod is disposed inside the column and associated with the sliding plate, the sliding plate is slidably disposed on the base plate, the fixing plate is connected to the sliding plate, and the drive arm is connected between the fixing plate and the linkage arm.

[0009] Furthermore, the connecting rod, through its own rotation, causes the sliding plate to slide vertically on the base plate. The sliding plate drives the driving arm connected to the fixed plate to move, thereby causing the linkage arm to open and close relative to the support base. The rust removal component is installed at the end of the linkage arm. The rust removal component includes a rust removal head, a connecting shaft, and a quick-release bolt. One end of the connecting shaft is connected to the linkage arm, and the other end is connected to the rust removal head through the quick-release bolt, so that the rust removal head can closely contact the inner wall of the composite pipe for operation. The fixing bolt is used to fasten the various components. The outer plate is set around the self-adaptive component to assist in adapting to the internal space of the composite pipe and to provide a limit for the connecting rod.

[0010] Preferably, in order to achieve overall rotational drive of the equipment, the drive motor serves as the power output source. After starting, the power is transmitted to the turntable via the drive wheel and the driven wheel. The turntable rotates and drives the base plate via the column, causing the adaptive component and the rust removal component to rotate as a whole.

[0011] Preferably, in order to achieve convenient manual diameter adjustment, after the handwheel is rotated, it is driven by the drive wheel and the driven wheel. The drive wheel drives the driven wheel to rotate, the driven wheel drives the connecting rod to rotate, and the rotation of the connecting rod drives the linkage arm to slide up and down, causing the sliding plate to slide up and down on the base plate accordingly.

[0012] Preferably, in order to enhance the support stability of the linkage mechanism, the bottom of the linkage arm is fixed to the support base. During the outward opening of the linkage arm, the support base is fixed to the base plate via the vertical rod to provide stable load-bearing support for the linkage arm and prevent the mechanism from shaking.

[0013] Preferably, in order to improve the replacement efficiency of vulnerable parts, the outer side of the linkage arm is connected to the rust removal assembly through the quick-release bolt and the connecting shaft, and the worn rust removal head can be quickly replaced by loosening the quick-release bolt.

[0014] Preferably, in order to ensure the structural strength of the transmission node, the sliding plate drives the drive arm connected to the fixed plate to move, and the connection points of each component are reinforced by high-strength fixing bolts.

[0015] Preferably, in order to protect the internal structure and improve the accuracy of operation, the outer plate is adapted to the internal space of the composite pipe and the connecting rod provides a limit, and the various structures work together in sequence to complete the rust removal operation on the inner wall of the composite pipe.

[0016] Preferably, in order to ensure the accuracy of transmission, the connecting rod is set inside the column and, through association with the sliding plate, provides precise support and transmission foundation for the positional adaptation of the rust removal operation using threaded or mechanical transmission principles.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem that existing pipe rust removal equipment typically uses a fixed-diameter grinding head, which cannot flexibly adapt to the inner diameter of different specifications of composite pipes, resulting in frequent shutdowns to replace the entire set of equipment or severe wear when dealing with multi-specification production tasks. It achieves the technical effect of stepless adjustment of the rust removal working diameter, ensuring that the rust removal head always adheres to the pipe wall with the best pressure, and significantly improving rust removal efficiency and equipment versatility.

[0018] 2. This utility model solves the problem of cumbersome replacement of worn parts in traditional rust removal devices by setting a connecting shaft and quick-release bolts between the end of the linkage arm and the rust removal head. This often requires disassembling the entire support rod for maintenance, resulting in long downtime for equipment maintenance. The new model achieves the technical effect of quickly replacing the rust removal head by simply loosening the quick-release bolts, greatly reducing maintenance difficulty and ensuring continuous operation of the composite pipe production line.

[0019] 3. This utility model solves the problem that cantilever rust removal mechanisms are prone to violent shaking due to centrifugal force or uneven pipe walls during high-speed rotation grinding, resulting in uneven rust removal or damage to the transmission screw. It achieves the technical effect of using the outer plate for auxiliary pre-positioning and limiting, and using the triangular linkage structure to enhance rigidity, thereby ensuring stable rust removal operation and extending the service life of the core transmission components.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] Example: Please refer to Figures 1 to 4 This utility model provides an inner wall rust removal device for composite pipe production, which aims to solve the technical problem that existing pipe rust removal equipment is difficult to adapt flexibly to composite pipes of various diameters, resulting in poor rust removal head fit and low operating efficiency.

[0024] like Figure 1As shown, the rust removal device for the inner wall of composite pipe production includes a base 1, a support 2 fixedly installed on the base 1, a turntable 8 rotatably mounted on the support 2, a column 3 fixedly connected to the top of the turntable 8 and extending vertically, an adaptive component 6 installed on the top of the column 3, and a rust removal component 7 connected to the end of the adaptive component 6. The base 1 serves as the basic load-bearing component of the entire device, providing a stable mounting plane for each moving component. The support 2 is constructed as a hollow or frame structure to be fixedly mounted on the top of the base 1. The turntable 8 is rotatably connected to the upper surface of the support 2 through a bearing assembly, enabling it to rotate circumferentially relative to the base 1. The column 3 serves as an intermediate transmission and support component, with its bottom end fixedly connected to the turntable 8 and an internal cavity for accommodating adjustment components. The top of the column carries the adaptive component 6, thereby transmitting the rotational motion of the turntable 8 to the working area above.

[0025] like Figure 1 and Figure 2 As shown, in order to provide the power and adjustment power required for rotary rust removal, a drive motor 5 is fixedly installed on the base 1. The drive motor 5 serves as the power output source, and its output shaft is connected to the turntable 8 through a transmission component. After starting, the power is transmitted to the turntable 8 through the drive wheel 11 and the driven wheel 10, which drives the column 3 and the adaptive component 6 and the rust removal component 7 to rotate synchronously, providing rotary cutting force for rust removal. At the same time, a handwheel 4 is rotatably installed on one side of the base 1. The handwheel 4 is used for manual input of adjustment actions. After the handwheel 4 rotates, it is transmitted through the drive wheel 11 and the driven wheel 10, which in turn drives the connecting rod 9 located inside the column 3 to rotate. The connecting rod 9 is located inside the column 3 and is associated with the sliding plate 602 in the adaptive component 6. The connecting rod 9 provides support and transmission foundation for the subsequent rust removal operation position adaptation through its own rotation. The drive wheel 11 and the driven wheel 10 serve as key transmission nodes here, connecting the power output of the drive motor 5 and the adjustment input of the handwheel 4 respectively, ensuring that the device has the dual functions of rotary rust removal and radial diameter change.

[0026] like Figure 3 and Figure 4As shown, the adaptive component 6, as the core variable-diameter actuator, includes a base plate 601, a sliding plate 602, an outer plate 603, a support base 604, a linkage arm 605, a drive arm 606, a fixing bolt 607, a vertical rod 608, and a fixing plate 609. The base plate 601 is horizontally fixed on the top plane of the column 3, providing the basic support for the entire adaptive component 6. The support base 604 is firmly fixed to the base plate 601 by the vertical rod 608. The bottom of the linkage arm 605 is rotatably connected to the support base 604, allowing the linkage arm 605 to open and close with the support base 604 as the fulcrum. The connecting rod 9 passes through the column 3 and establishes a transmission connection with the sliding plate 602. The sliding plate 602 is slidably positioned above the base plate 601. The fixing plate 609 is fixedly connected to the side of the sliding plate 602. The two ends of the drive arm 606 are respectively hinged between the fixing plate 609 and the linkage arm 605. The sliding plate 602 is driven to move on the base plate by the rotation of the connecting rod 9. The sliding plate 602 drives the drive arm 606 connected to the fixed plate 609 to move, thereby causing the linkage arm 605 to deflect at an angle relative to the support base 604, realizing the adjustment of the radial dimension. The outer plate 603 is set on the outside of the adaptive component 6 to assist in adapting to the internal space of the composite pipe and to provide limit protection for the connecting rod 9. The fixing bolt 607 passes through each hinge node for fastening and rotating the connection of each component. The rust removal component 7 includes a rust removal head 701, a connecting shaft 702 and a quick-release bolt 703. The rust removal component 7 is installed at the end of the linkage arm 605 away from the support base 604. The rust removal head 701 directly contacts the inner wall of the composite pipe for grinding. One end of the connecting shaft 702 is connected to the linkage arm 605, and the other end is connected to the rust removal head 701 through the quick-release bolt 703. The quick-release bolt 703 allows the rust removal head 701 to be quickly disassembled and replaced. The components cooperate with each other to form an organic whole and jointly complete the adaptive rust removal operation of the inner wall of the composite pipe.

[0027] To solve the above-mentioned technical problems, the inner wall rust removal device for composite pipe production also includes an adaptive component 6 for radial adjustment and adaptive fitting. Furthermore, the adaptive component 6 forms a specific structural fit and linkage relationship with the aforementioned column 3 and connecting rod 9. Through the coordinated action of the internal linkage mechanism, the vertical driving force is converted into the horizontal expansion force, thereby flexibly adapting to composite pipes with different inner diameters.

[0028] Please refer to the following carefully. Figure 3 and Figure 4 The following is a detailed description of the core adaptive and rust-removing structure: The adaptive component 6 is located at the top of the column 3. Its main body includes a base plate 601, which is horizontally fixed in a disc shape on the top end face of the column 3, providing a stable mounting reference surface for the entire component. A sliding plate 602 is slidably fitted in the upper central area of ​​the base plate 601. The sliding plate 602 is constructed as a disc-shaped structure that can move up and down in the vertical direction. Its bottom is connected to a connecting rod 9 that penetrates the interior of the column 3. When the connecting rod 9 rotates or moves axially inside the column 3, it can drive the sliding plate 602. The base plate 601 has a lifting displacement relative to the base plate 601. Multiple vertical rods 608 are evenly distributed and fixed on the outer periphery of the upper surface of the base plate 601. Each vertical rod 608 has a support base 604 fixedly connected to its top end. The support base 604 serves as the fixed fulcrum of the linkage mechanism. A linkage arm 605 is rotatably mounted on it. The bottom end of the linkage arm 605 is hinged to the support base 604 through a pin or other rotating connector, so that the linkage arm 605 can swing around the hinge point in the vertical plane, thereby changing the radial position of its top end.

[0029] To convert the lifting motion of the sliding plate 602 into the swinging motion of the linkage arm 605, multiple outwardly extending fixed plates 609 are fixedly connected to the outer edge of the sliding plate 602. Each fixed plate 609 corresponds to a linkage arm 605 assembly. The drive arm 606 serves as an intermediate transmission rod, with its inner end rotatably connected to the fixed plate 609 and its outer end rotatably connected to the middle position of the linkage arm 605. Fixing bolts 607 are provided at the rotation nodes between each component. The fixing bolts 607 not only serve as a connection and fastening function but also act as a rotation axis, allowing the components to rotate relative to each other. When the connecting rod 9 drives the sliding plate 602 to move upward, the sliding plate 602 drives the inner end of the drive arm 606 to rise through the fixed plate 609. The drive arm 606 then pushes the linkage arm 605 to open outward around the support base 604. Conversely, when the sliding plate 602 descends, the linkage arm 605 retracts inward. This linkage transmission structure ensures that the rust removal device can continuously and steplessly adjust the working diameter to accurately match the inner wall size of the composite pipe to be processed.

[0030] The rust removal component 7 is installed at the free end of the linkage arm 605 and is directly responsible for the physical grinding of the pipe wall. The rust removal component 7 includes a rust removal head 701 that is rotatably connected to the top of the linkage arm 605 via a connecting shaft 702. The connecting shaft 702 is arranged laterally, allowing the rust removal head 701 to be finely adjusted within a certain range to better fit the curvature of the pipe wall. The outer surface of the rust removal head 701 is provided with a wear-resistant grinding layer or bristles for removing rust. A quick-release bolt 703 is also provided between the connecting shaft 702 and the rust removal head 701. The quick-release bolt 703 passes through the connection part, allowing the rust removal head 701 to be easily removable. After wear, the operator does not need to disassemble the entire linkage mechanism. He only needs to loosen the quick-release bolt 703 to quickly replace the new rust removal head 701, which greatly improves the maintenance efficiency and operation continuity of the equipment. In addition, an outer plate 603 is fixedly installed at the top center of the adaptive component 6. The outer plate 603 covers the sliding plate 602 in the shape of a cover plate, which plays the role of dust prevention and protection of the internal mechanism. At the same time, it also provides a limit to the upward stroke of the connecting rod 9 to prevent the mechanism from being over-opened and causing damage. All the structures work together in sequence to form an efficient and flexible internal wall rust removal operation system.

[0031] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, to enhance the stability and adaptability of the adaptive component 6 when operating inside the composite pipe, please refer to... Figure 3 The adaptive component 6 also includes an outer plate 603 disposed on the periphery. The outer plate 603 is constructed as an arc-shaped or ring-shaped plate structure and is fixedly connected to the outer wall of the linkage arm 605 by a bracket or bolts. It is located below or to the side of the rust removal head 701. The outer diameter of the outer plate 603 is designed to be slightly smaller than the minimum working inner diameter of the composite pipe. During the rust removal operation, the outer plate 603 can assist the rust removal head 701 in pre-positioning the internal space of the composite pipe to prevent the rust removal component 7 from violently jumping due to the unevenness of the inner wall of the pipe. At the same time, the outer plate 603 can also provide a certain degree of protection and shielding for the internal connecting rod 9 and linkage mechanism, reducing the entry of splashed rust slag into the precision transmission parts, thereby extending the service life of the device.

[0032] As another preferred embodiment, in order to ensure a more stable and reliable transmission connection between the drive arm 606, the linkage arm 605, and the sliding plate 602, multiple fixing plates 609 are integrally formed or welded on the outer periphery of the sliding plate 602. Each fixing plate 609 has a precision pin hole. The end of the drive arm 606 is embedded in the mounting groove of the fixing plate 609 and is hinged by high-strength fixing bolts 607 passing through the pin holes. This structural design not only increases the contact area of ​​the connection parts and reduces the stress concentration per unit area, but also effectively prevents the connection from loosening due to long-term high-frequency vibration, ensuring the accurate transmission of the diameter adjustment action.

[0033] As another preferred embodiment, in order to facilitate the quick maintenance and replacement of the rust removal head 701 and improve on-site operation efficiency, the rust removal component 7 adopts a quick-release design. The end of the connecting shaft 702 is provided with an installation groove or threaded hole, and the back of the rust removal head 701 is provided with a matching installation handle. The quick-release bolt 703 passes horizontally through the connection part between the connecting shaft 702 and the rust removal head 701 and locks it. When the abrasive layer on the surface of the rust removal head 701 is worn away, the operator does not need to use complicated tools. He only needs to loosen the quick-release bolt 703 to remove the old rust removal head 701 and replace it with a new one. The whole process is simple and quick, which greatly shortens the equipment downtime for maintenance and ensures the continuous operation of the composite pipe production line.

[0034] As another preferred embodiment, in order to achieve independent and precise adjustment of the connecting rod 9, please refer to... Figure 1 and Figure 2 The handwheel 4 is connected to the connecting rod 9 through an independent gear transmission mechanism. Specifically, the driving wheel 11 is coaxially fixed on the rotating shaft of the handwheel 4, and the driven wheel 10 is fixedly sleeved on the end of the connecting rod 9 that extends out of the bottom of the column 3. The driving wheel 11 and the driven wheel 10 mesh with each other. This design tightly couples the manual operation of the handwheel 4 with the rotation of the connecting rod 9. The operator can precisely control the opening degree of the high-altitude adaptive component 6 by rotating the handwheel 4 from the ground, without having to climb to a height. This is both safe and convenient. At the same time, the gear transmission has the advantages of accurate transmission ratio and no slippage, ensuring a smooth and stable adjustment process.

[0035] The working principle of this utility model's inner wall rust removal device for composite pipe production is as follows: Before starting the rust removal operation on the inner wall of the composite pipe, the composite pipe to be treated is first placed in the work area, and the column 3 and the self-adaptive component 6 at the top of the device are inserted into the inner cavity of the composite pipe. At this time, the operator rotates the handwheel 4 to make radial adjustments according to the specific inner diameter of the composite pipe. The rotation of the handwheel 4 drives the coaxial driving wheel 11 to rotate, and the driving wheel 11 drives the driven wheel 10 to rotate through meshing. Since the driven wheel 10 is fixedly connected to the bottom end of the connecting rod 9, the connecting rod 9 rotates accordingly inside the column 3.

[0036] The rotation of the connecting rod 9 is converted into the vertical lifting and lowering motion of the sliding plate 602 through the transmission mechanism. Specifically, when the connecting rod 9 rotates in the forward direction, it drives the sliding plate 602 to move upward. The upward movement of the sliding plate 602 causes the fixed plate 609 fixed on it to rise synchronously, and the fixed plate 609 in turn pulls the inner end of the drive arm 606 hinged on it to lift up. Since the outer end of the drive arm 606 is hinged to the middle of the linkage arm 605, and the bottom end of the linkage arm 605 is hinged to the fixed support base 604, the upward lifting force of the drive arm 606 forces the linkage arm 605 to open and swing outward around the support base 604. The opening action of the linkage arm 605 causes the rust removal component 7 at its top to expand radially outward until the rust removal head 701 is tightly attached to the inner wall surface of the composite pipe, thereby completing the adaptive adjustment for a specific pipe diameter.

[0037] After radial fitting adjustment is completed, drive motor 5 is started. Drive motor 5 outputs power, driving turntable 8 to rotate at high speed on support base 2 through transmission system. The rotation of turntable 8 causes column 3 and all adaptive components 6 and rust removal components 7 installed on top of column 3 to rotate synchronously. At this time, the rust removal head 701, which is close to the pipe wall, performs high-speed circumferential grinding on the inner wall of the composite pipe under the combined action of centrifugal force and mechanical support force, effectively removing rust and impurities from the inner wall. During the rust removal process, outer plate 603 helps maintain the concentricity of the device inside the pipe and prevents excessive swaying.

[0038] When the rust removal head 701 wears out due to prolonged friction and needs replacement, the operator stops the drive motor 5 and removes the device from the pipe. Then, loosening the quick-release bolt 703 allows the old rust removal head 701 to be removed from the connecting shaft 702, and a new rust removal head 701 can be quickly installed. Tightening the quick-release bolt 703 again allows operation to resume. The entire process does not require disassembling the complex linkage mechanism, ensuring high production efficiency.

[0039] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
