Description

Technical Field

[0001] This utility model relates to the technical field of pipeline anti-corrosion and rust prevention equipment, specifically a rust removal device for the inner wall of a pipeline. Background Technology

[0002] Pipelines are essential components for transporting fluids, powdery solids, and exchanging heat energy, playing a vital role in water conservancy projects and the transportation of oil and natural gas. To ensure the safety and stability of pipelines during long-term use, anti-corrosion treatment is necessary. However, since rust easily forms on the inner surface of metal pipelines during installation, rust removal is required before anti-corrosion treatment. Currently, manual shot blasting or ball-driving is mainly used to remove rust from the inner wall of steel pipes. However, the internal space of pipelines is small, and this method results in high labor intensity for workers, affecting their health and safety, and also has low production efficiency and affects construction efficiency. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a pipe inner wall rust removal device to solve the problem of high labor intensity and impact on workers' health and safety during the pipe inner wall rust removal process.

[0004] The technical solution adopted by this utility model is: a pipe inner wall rust removal device, including a laser rust remover and a movable support. The bottom of the movable support is equipped with a first driving mechanism for driving the movable support to move. The first driving mechanism is connected to the movable support through a lifting mechanism. A rotating mechanism is provided in the middle of the movable support. The output end of the rotating mechanism is connected to a rotating support for installing the laser rust remover. Several sets of flip-open auxiliary support components are provided on the outside of the movable support. The auxiliary support components include an auxiliary support frame and several support wheels installed in the auxiliary support frame.

[0005] The above structure has the following beneficial effects: 1. The rotating mechanism drives the laser rust remover to rotate along with the rotating bracket, enabling the laser rust remover to remove rust from the inner wall of the pipe 360 ​​degrees. At the same time, the moving bracket moves the laser rust remover under the action of the first drive mechanism, thereby achieving uniform and stable automatic rust removal of the entire inner wall of the pipe. This avoids the need for personnel to enter the pipe to remove rust, greatly reducing the labor intensity of workers and reducing the health and safety risks caused by rust removal work.

[0006] 2. The lifting mechanism can drive the first drive mechanism to lift and lower, thereby adjusting the height of the laser rust remover. This allows the laser rust remover to remain in the center of the pipe when removing rust from pipes of different inner diameters, thereby improving the uniformity of rust removal and enhancing the rust removal effect.

[0007] 3. During the movement of the moving support driven by the first drive mechanism, the auxiliary support frame abuts against the inner wall of the pipe through the support wheels to prevent the moving support from tipping over during movement, thereby improving the stability of the moving support during movement and ensuring that the rust removal efficiency is not affected.

[0008] Preferably, the lifting mechanism includes a lifting bracket fixedly mounted on the movable bracket and a second driving member mounted on the lifting bracket. The output end of the second driving member is connected to a lead screw. A connecting block is provided on the side of the first driving mechanism, and a threaded hole for cooperating with the lead screw is provided on the connecting block.

[0009] The second driving component drives the lead screw to rotate, thereby causing the connecting block connected to the lead screw to move vertically. This effectively and stably drives the lifting bracket to rise and fall, achieving precise adjustment of the height of the laser rust remover.

[0010] Preferably, the lifting bracket is further provided with first guide rods on both sides, and the first drive mechanism is further provided with guide blocks on its side, and the guide blocks are provided with first guide holes for cooperating with the first guide rods.

[0011] The guide block cooperates with the first guide rod through the first guide hole, making the movement of the lifting mechanism safer and more stable, and avoiding the probability of the moving support shaking during the movement, so as to achieve a uniform and stable rust removal effect.

[0012] Preferably, the auxiliary support frame also has a mounting bracket for mounting the support wheel slidably connected inside, the mounting bracket is also connected to a support plate, the support plate is provided with a second guide rod, the mounting bracket is provided with a second guide hole for cooperating with the second guide rod, the end of the second guide rod is provided with a limit block, the mounting bracket is slidably engaged with the second guide rod through the second guide hole, the second guide rod is also provided with a first elastic element, one end of the first elastic element abuts against the support plate, and the other end of the first elastic element abuts against the mounting bracket.

[0013] This design allows the mounting bracket to slide along the second guide rod. Meanwhile, the first elastic element uses a compression spring, which, under its action, causes the support wheel to tend to move outward toward the auxiliary support frame. This allows the support wheel to stably abut against the inner wall of the pipe. The limiting block at the end of the second guide rod can limit the second guide rod and the mounting bracket, preventing the second guide rod from separating from the mounting bracket.

[0014] Preferably, the support plate is provided with a positioning shaft, and the auxiliary support frame is provided with a plurality of positioning holes for cooperating with the positioning position.

[0015] By matching the positioning shaft with different positioning holes, the length of the mounting bracket extending out of the auxiliary support bracket can be adjusted. This allows the support wheel to stably abut against the inner wall of the pipe when removing rust from pipes with different inner diameters.

[0016] Preferably, an adjustment hole is provided on one side of the positioning hole, and several positioning holes are connected through the adjustment hole. The positioning shaft is rotatably connected to the support plate, and the positioning shaft can slide in the adjustment hole.

[0017] The adjustment hole connects all the positioning holes, so that when adjusting the position of the mounting bracket, it is only necessary to turn the positioning shaft so that the positioning shaft enters the adjustment hole, and the support plate can drive the mounting bracket to move along the adjustment hole. When it moves to the desired position, turn the positioning shaft so that it is inserted into the corresponding positioning hole to achieve the positioning of the support plate.

[0018] Preferably, a second elastic element is provided between the positioning shaft and the mounting bracket.

[0019] The second elastic element is a torsion spring. The second elastic element makes the positioning shaft tend to move towards the positioning hole. This ensures that the positioning shaft will not easily separate after it is engaged with the positioning hole, and ensures that the device is safe and stable during use.

[0020] Preferably, the auxiliary support frame is provided with a limiting hole on its side, and the movable bracket is provided with a through hole that matches the position of the limiting hole, and a limiting shaft for insertion into the limiting hole is slidably connected in the through hole.

[0021] After the rust removal work is completed, the auxiliary support frame can be rotated into the movable bracket and inserted into the through hole through the limiting shaft to limit the auxiliary support frame so as to facilitate the storage of the device.

[0022] Preferably, the limiting shaft is provided with a first boss and a second boss, the first boss is located on the outside of the movable bracket, the second boss is located on the inside of the movable bracket, and a third elastic member is also installed on the limiting shaft. One end of the third elastic member abuts against the second boss, and the other end of the third elastic member abuts against the side wall of the movable bracket. A handle is also provided at the end of the limiting shaft located on the outside of the movable bracket.

[0023] The first and second protrusions can limit the positioning shaft, while the third elastic element is a compression spring, which can make the positioning shaft tend to move inward toward the inside of the moving bracket, thereby keeping the positioning shaft inserted in the through hole and preventing it from easily separating, ensuring a stable storage state. The handle makes it easy to unlock the auxiliary support frame.

[0024] Preferably, the auxiliary support frame is also provided with a guide platform, the limiting hole is located on the guide platform, and one side of the guide platform is an inclined surface.

[0025] The inclined surface on one side of the guide platform allows the auxiliary support frame to push the limiting shaft to move when it is stored. When the through hole coincides with the limiting shaft, the limiting shaft is automatically inserted into the through hole under the action of the third elastic element, thereby locking the auxiliary support frame, which is more convenient and faster.

Detailed Implementation

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] Example 1 According to the instruction manual Figure 1-8 As shown, this utility model provides a pipe inner wall rust removal device, including a movable support 20. A first drive mechanism 30 for moving the movable support 20 is installed at the bottom of the movable support 20. In this embodiment, the first drive mechanism 30 includes a drive motor and four drive rollers. A lifting mechanism 40 for raising and lowering the first drive mechanism 30 is also provided between the first drive mechanism 30 and the movable support 20. In this embodiment, the lifting mechanism 40 includes a lifting bracket 41 fixedly installed on the movable support 20 and a second drive component installed on the lifting bracket 41. The second drive component is a servo motor, and its output end is connected to a lead screw via a gear set. 42. A connecting block is fixedly connected to the side of the first drive mechanism 30, and a threaded hole that mates with the lead screw 42 is provided on the connecting block. In this embodiment, two lead screws 42 are symmetrically arranged. Each of the two lead screws 42 is connected to a servo motor, and both motors are connected to a servo controller to ensure that the two lead screws 42 rotate synchronously and at the same speed, thereby ensuring that the two sides of the moving bracket 20 can rise and fall synchronously. In this embodiment, the first drive mechanism 30, the rotating mechanism 12, and the laser rust remover 11 are all connected to a controller. The controller is a microcomputer and is connected to a wireless control module, which can be remotely controlled by a mobile phone or other wireless terminal.

[0037] To ensure the stability of the movable support 20 during lifting, first guide rods 43 are fixedly installed on both sides of the lifting support 41, and guide blocks are fixedly installed on the side of the first drive mechanism 30. A first guide hole is provided on the guide block to cooperate with the first guide rods 43.

[0038] A rotating mechanism 12 is also installed in the middle of the movable support 20. The rotating mechanism 12 is a motor. The output end of the rotating mechanism 12 is connected to the rotating support 13. A laser rust remover 11 is installed on the outer periphery of the rotating support 13. The laser rust remover 11 can rotate together with the rotating support 13. In this example, the laser rust remover 11 is installed on the rotating support 13 at an angle to the outside of the movable support 20, so that it can remove rust in the direction of movement and avoid the laser being blocked by the movable support 20.

[0039] In this embodiment, four sets of flip-open auxiliary support assemblies are also installed on the outer side of the movable bracket 20. Each auxiliary support assembly includes an auxiliary support frame 51 and auxiliary support wheels 52. A mounting frame 53 for mounting the support wheels 52 is slidably connected inside the auxiliary support frame 51. A support plate 54 is slidably connected above the mounting frame 53. A second guide rod 55 is provided on the support plate 54. A second guide hole is provided on the mounting frame 53 to cooperate with the second guide rod 55, allowing the mounting frame 53 to slide along the second guide rod 55. A limiting block 551 is provided at the end of the second guide rod 55. The diameter of the limiting block 551 is larger than the diameter of the second guide hole. The limiting block 551 can prevent the mounting bracket 53 from separating from the second guide rod 55. In this embodiment, a first elastic element 56 is also provided on the second guide rod 55. The first elastic element 56 is a compression spring. One end of the first elastic element 56 abuts against the support plate 54, and the other end of the first elastic element 56 abuts against the mounting bracket 53. The first elastic element 56 enables the roller to abut against the inner wall of the pipe stably.

[0040] In this embodiment, a fourth elastic element is provided between the auxiliary support frame 51 and the movable bracket 20. The fourth elastic element is a torsion spring. A baffle 21 fixedly connected to the movable bracket 20 is also provided on one side of the auxiliary support frame 51. The auxiliary support frame 51 abuts against the baffle 21 under the action of the fourth elastic element, and the position of the auxiliary support frame 51 is restricted by the baffle 21.

[0041] In this embodiment, a positioning groove is also provided on the support plate 54, and a vertically arranged rotating shaft is provided in the positioning groove. The positioning shaft 57 is rotatably connected to the rotating shaft. At the same time, four positioning holes 511 for cooperating with the positioning shaft 57 are provided on the auxiliary support frame 51. An elongated adjustment hole 512 is also provided on one side of the positioning hole 511. The adjustment hole 512 is connected to the four positioning holes 511, so that the positioning shaft 57 can slide in the adjustment hole 512 and enter each positioning hole 511 through the adjustment hole 512. By pulling the positioning shaft 57 into different positioning holes 511, the length of the support roller extending out of the auxiliary support frame 51 can be adjusted, thereby adapting to pipes with different inner diameters.

[0042] In this embodiment, a second elastic element is also installed between the positioning shaft 57 and the rotating shaft. The second elastic element is a torsion spring. The torsion spring causes the positioning shaft 57 to tend to move toward the positioning hole 511, so that the positioning shaft 57 can be kept in the positioning hole 511 under normal conditions and will not easily separate from the positioning hole 511. When it is necessary to adjust the extension length of the support roller, the positioning shaft 57 can be adjusted by moving it. After the adjustment is completed, the positioning shaft 57 is released, and the positioning shaft 57 can be locked in the positioning hole 511 under the action of the second elastic element, ensuring the stability of the device during use.

[0043] In this embodiment, a guide platform 514 is also provided on the side of the auxiliary support frame 51. One side of the guide platform 514 is inclined, and a limiting hole 513 is provided on the guide platform 514. A through hole is provided on the side of the movable bracket 20, and a limiting shaft 60 is slidably connected in the through hole. The limiting shaft 60 can be inserted into the limiting hole 513. The limiting shaft 60 can limit the auxiliary support frame 51 so that the auxiliary support frame 51 can be stored normally. In this embodiment, the limiting shaft 60 is provided with a first protrusion 61 and a second protrusion 62. The first protrusion 61 is located on the outer side of the movable bracket 20, and the second protrusion 62 is located on the inner side of the movable bracket 20. A third elastic element 63 is also installed on the limiting shaft 60. The third elastic element 63 is a compression spring. One end of the third elastic element 63 abuts against the second protrusion 62, and the other end of the third elastic element 63 abuts against the side wall of the movable bracket 20. A handle 64 is also provided at the end of the limiting shaft 60 located on the outer side of the movable bracket 20. The first protrusion 61 and the second protrusion 62 can limit the limiting shaft 60. At the same time, the third elastic element 63, being a compression spring, can make the limiting shaft 60 tend to move towards the inside of the movable bracket 20, thereby keeping the limiting shaft 60 inserted inside the through hole and preventing it from easily separating, ensuring a stable storage state. The handle 64 facilitates unlocking the auxiliary support frame 51.

[0044] Its working principle is as follows: when it is necessary to remove rust from the inner wall of the pipe, first adjust the lifting mechanism 40 so that the axis of the rotating bracket 13 is basically aligned with the axis of the pipe to achieve a better rust removal effect. Then, pull the handles 64 on both sides of the moving bracket 20 to unlock the auxiliary support frame 51. Under the action of the fourth elastic element, the auxiliary support frame 51 rotates and abuts against the baffle 21. Then, move the positioning shaft 57 to adjust the position of the support roller so that the support roller abuts against the side wall of the pipe. After the adjustment is completed, the staff can use the wireless controller to remotely control the equipment, start the rotating mechanism 12 to make the laser rust remover 11 rotate with the rotating bracket 13, and at the same time start the laser rust remover 11 and the first drive mechanism 30 so that the laser rust remover 11 rotates while removing rust and moves inside the pipe to achieve automatic rust removal of the pipe.
