Description

Technical Field

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

[0002] Pipelines are essential components for transporting fluids, powdery solids, and exchanging heat energy. They play 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 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. This method results in high labor intensity for workers, affects their health and safety, and has low production efficiency, impacting construction efficiency. Summary of the Invention

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

[0004] The technical solution adopted by this utility model is as follows: a pipe rust removal device, including a laser rust remover and a movable support. The bottom of the movable support is provided with a plurality of first rollers. A rotating support is mounted on the movable support and is rotatably connected to the movable support. The laser rust remover is mounted on the rotating support. A lifting support for driving the rotating support to rise and fall is also installed between the rotating support and the movable support. The lifting support is slidably connected to the movable support, and a first driving mechanism is installed between the lifting support and the movable support. The rotating support is connected to a second driving mechanism for driving the rotating support to rotate.

[0005] The above structure has the following beneficial effects:

[0006] 1. The movable support moves the laser rust remover through the pipeline. At the same time, rotating the support causes the laser rust remover to rotate along the pipeline axis, thereby uniformly and comprehensively removing rust from the inner wall of the pipeline. This eliminates the need for workers to manually remove rust with the rust remover, effectively avoiding the health and safety issues associated with rust removal work.

[0007] 2. Using a laser rust remover to remove rust from the inner wall of the pipe can improve rust removal efficiency and reduce the generation of dust and impurities during the rust removal process, further avoiding the health and safety issues of workers during rust removal work.

[0008] 3. The lifting bracket can move the laser rust remover up and down, thus adjusting its height so that it can be positioned on the axis of the pipe when removing rust from pipes of different diameters. This ensures that every part of the pipe's inner wall receives a uniform rust removal effect during the rust removal process, thereby improving the overall rust removal efficiency.

[0009] Preferably, the first driving mechanism includes a first driving member, a lead screw rotatably mounted on the movable bracket, and a slider connected to the lifting bracket, wherein the slider is provided with a thread that cooperates with the lead screw.

[0010] The first driving component drives the lead screw to rotate, thereby causing the slider that cooperates with the lead screw to rise and fall, enabling precise adjustment of the height of the laser rust remover. At the same time, the lead screw has a self-locking function, which allows the laser rust remover to maintain a stable height after the height adjustment is completed, and it will not easily deviate from the set height.

[0011] Preferably, the movable support is also provided with a guide rod, and the slider is provided with a guide hole that cooperates with the guide rod.

[0012] The guide rod and guide hole design enable the slider to remain stable during height adjustment.

[0013] Preferably, auxiliary support plates are rotatably connected to both sides of the movable bracket, and several second rollers are installed at the bottom of the auxiliary support plates.

[0014] After the auxiliary support plate is flipped over, the second roller can abut against the side wall of the pipe, making the moving support more stable during movement. At the same time, the auxiliary support plate can be flipped at different angles according to the inner diameter of the pipe, and the second roller can abut against the inner side wall of the pipe stably.

[0015] Preferably, a ratchet assembly is also installed between the auxiliary support plate and the movable bracket. The ratchet assembly includes a ratchet connected to the auxiliary support plate and a pawl rotatably connected to the movable bracket. One end of the pawl abuts against the ratchet, and the other end of the pawl extends to the outside of the movable bracket. A first elastic element is also installed between the pawl and the movable bracket.

[0016] The ratchet assembly ensures that the auxiliary support plate opens unimpeded, allowing the second roller to smoothly abut against the inner wall of the pipe. Simultaneously, when the auxiliary support plate flips to the appropriate position, the ratchet is obstructed by the pawl, preventing the auxiliary support plate from flipping away from the inner wall of the pipe. This ensures that the second roller provides continuous and stable support. The first elastic element is a torsion spring, which allows the pawl to stably limit the movement under normal conditions. When the auxiliary support plate needs to be retracted, pressing the other end of the pawl separates it from the ratchet, causing the auxiliary support plate to flip in the opposite direction for easy resetting.

[0017] Preferably, a second elastic element is also installed between the auxiliary support plate and the movable bracket.

[0018] The second elastic element also adopts a torsion spring. The second elastic element makes the auxiliary support plate tend to rotate away from the pipe side wall. On the one hand, it can facilitate the reset of the auxiliary support plate. On the other hand, the second elastic element can provide auxiliary support for the auxiliary support plate, so that the auxiliary support plate will not easily flip further towards the pipe side wall, thereby ensuring that both the first roller and the second roller can stably abut against the pipe side wall.

[0019] Preferably, the movable bracket is also equipped with a first buckle, and the auxiliary support plate is also provided with a first slot that cooperates with the first buckle.

[0020] The engagement between the first buckle and the first slot allows the auxiliary support plate to be fixed in a vertical position after it is flipped and reset. This facilitates the storage of the device and reduces space occupation, while also making it easy to reuse in the future. Simply press the other end of the first buckle to separate it from the first slot, and the auxiliary support plate can be rotated.

[0021] Preferably, a roller position adjustment mechanism is also provided between the auxiliary support plate and the second roller. The roller position adjustment mechanism includes an adjustment shaft located at the end of the auxiliary support plate and an adjustment roller rotatably connected to the adjustment shaft. The second roller is connected to the adjustment roller. A first positioning screw hole is provided on the side of the adjustment roller. A plurality of second positioning holes for cooperating with the first positioning screw hole are provided on the side of the auxiliary support plate.

[0022] The second roller can rotate along the adjusting shaft via the adjusting roller, thereby allowing the first positioning screw hole on the adjusting roller to engage with different second positioning holes. At this point, a bolt needs to be inserted and screwed in to fix the relative position of the adjusting roller and the adjusting shaft, thus achieving the adjustment of the angle of the second roller. Adjusting the angle of the second roller ensures that it can stably abut against the inner wall of the pipe when dealing with pipes of different inner diameters, thereby enabling the device to move stably.

[0023] Preferably, a fan is also installed on the movable support, and the fan is located on the side of the movable support away from the laser rust removal instrument.

[0024] The fan allows air to circulate inside the pipe, which on the one hand prevents debris or impurities generated during the rust removal process from falling onto key components such as the rotating bracket and laser rust remover, thus preventing damage to them due to impurities. On the other hand, it also balances the weight at both ends of the device, making its movement more stable.

[0025] Preferably, a first camera is mounted on the rotating bracket, a second camera is mounted on the movable bracket, and a fill light is mounted on the movable bracket.

[0026] The first camera rotates along with the laser rust remover to monitor the rust removal effect in real time. The second camera monitors the overall rust removal effect to ensure excellent and stable results. The supplementary lighting illuminates the inside of the pipe to facilitate monitoring of the rust removal effect. Attached Figure Description

Detailed Implementation

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] Example 1

[0039] According to the instruction manual Figure 1-7 As shown, this utility model provides a pipe rust removal device, including a laser rust remover 10 and a movable support 20. The bottom of the movable support 20 is provided with a plurality of first rollers 21. A rotating support 30, rotatably connected to the movable support 20, is mounted on the movable support 20. The laser rust remover 10 is mounted on the rotating support 30. A lifting support 40, used to drive the rotating support 30 to rise and fall, is also installed between the rotating support 30 and the movable support 20. The lifting support 40 is slidably connected to the movable support 20, and a first roller 21 is installed between the lifting support 40 and the movable support 20. A drive mechanism 50 is provided, and a second drive mechanism for driving the rotating bracket 30 to rotate is connected to the rotating bracket 30. In this embodiment, the second drive mechanism is a stepper motor, which is fixedly installed in the lifting bracket 40, and the output shaft of the stepper motor is connected to the rotating bracket 30. The stepper motor can drive the laser rust remover 10 to rotate stably, thereby performing 360-degree rust removal on the inner wall of the pipe. In this example, a third drive mechanism for driving the first roller 21 to move is also installed inside the movable bracket 20. The third drive mechanism is a motor.

[0040] In this embodiment, the first driving mechanism 50 includes a first driving component, a lead screw 51 rotatably mounted on the movable support 20, and a slider 52 connected to the lifting support 40. The slider 52 is provided with a thread that cooperates with the lead screw 51. The first driving component is a motor, which is fixedly installed inside the movable support 20. The motor drives the lead screw 51 to rotate, thereby causing the slider 52 that cooperates with the lead screw 51 to rise and fall. This enables precise adjustment of the height of the laser rust remover 10. At the same time, the lead screw 51 has a self-locking function, which allows the laser rust remover 10 to maintain a stable height after the height adjustment is completed and not to easily deviate from the set height. The movable support 20 is also provided with a guide rod 53, and the slider 52 is provided with a guide hole that cooperates with the guide rod 53. The guide rod 53 and the guide hole enable the slider 52 to remain stable during the height adjustment process.

[0041] In this example, auxiliary support plates 60 are rotatably connected to both sides of the movable support 20. Several second rollers 61 are installed at the bottom of the auxiliary support plates 60. A ratchet assembly 62 is also installed between the auxiliary support plates 60 and the movable support 20. The ratchet assembly 62 includes a ratchet 621 connected to the auxiliary support plates 60 and a pawl 622 rotatably connected to the movable support 20. One end of the pawl 622 abuts against the ratchet 621, and the other end extends to the outside of the movable support 20. A first elastic element is also installed between the pawl 622 and the movable support 20. The ratchet assembly 62 ensures that the auxiliary support plates 60 are opened without obstruction, allowing the second rollers 61 to smoothly abut against the inner wall of the pipe. Simultaneously, when the auxiliary support plates 60 are flipped to the corresponding position, the ratchet 62... 1. The pawl 622 prevents the auxiliary support plate 60 from flipping away from the inner wall of the pipe, thus ensuring that the second roller 61 can provide continuous and stable support. In this example, the first elastic element is a torsion spring, which allows the pawl 622 to stably limit the movement under normal conditions. When the auxiliary support plate 60 needs to be retracted, pressing the other end of the pawl 622 separates it from the ratchet 621, allowing the auxiliary support plate 60 to flip in the opposite direction for easy reset. After the auxiliary support plate 60 flips, the second roller 61 can abut against the side wall of the pipe, making the movable bracket 20 more stable during movement. The auxiliary support plate 60 can be opened at different angles depending on the inner diameter of the pipe, and the second roller 61 can always abut against the inner wall of the pipe.

[0042] A second elastic element is also installed between the auxiliary support plate 60 and the movable bracket 20. In this example, the second elastic element is also a torsion spring. The second elastic element gives the auxiliary support plate 60 a tendency to rotate away from the pipe sidewall. On the one hand, this facilitates the reset of the auxiliary support plate 60, and on the other hand, the second elastic element provides auxiliary support for the auxiliary support plate 60, preventing it from easily flipping further towards the pipe sidewall. This ensures that both the first roller 21 and the second roller 61 can stably abut against the pipe sidewall. At the same time, the movable bracket... The auxiliary support plate 60 is also equipped with a first buckle 22 and a first slot 63 that cooperates with the first buckle 22. The cooperation between the first buckle 22 and the first slot 63 can be achieved after the auxiliary support plate 60 is flipped and reset, thereby fixing the auxiliary support plate 60 in a vertical position. This makes it easier to store the device and reduce the space occupied, and also makes it easier to use it again later. It is only necessary to press the other end of the first buckle 22 to separate it from the first slot 63 to unlock it, thereby allowing the auxiliary support plate 60 to rotate.

[0043] In this embodiment, a roller position adjustment mechanism is also provided between the auxiliary support plate 60 and the second roller 61. The roller position adjustment mechanism includes an adjustment shaft 66 located at the end of the auxiliary support plate 60 and an adjustment roller 64 rotatably connected to the adjustment shaft 66. The second roller 61 is connected to the adjustment roller 64. A first positioning screw hole is provided on the side of the adjustment roller 64. A plurality of second positioning holes 65 for cooperating with the first positioning screw hole are provided on the side of the auxiliary support plate 60. The second roller 61 can rotate along the adjustment shaft 66 through the adjustment roller 64, so that the first positioning screw hole on the adjustment roller 64 cooperates with different second positioning holes 65. At this time, it is necessary to insert a bolt and screw it in to fix the relative position of the adjustment roller 64 and the adjustment shaft 66, thereby realizing the adjustment of the angle of the second roller 61. Adjusting the angle of the second roller 61 enables it to stably abut against the inner wall of the pipe when dealing with pipes of different inner diameters, thereby making the device move stably.

[0044] Its working principle is as follows: when pipe rust removal is required, the pipe rust removal device is pushed into the inside of the pipe, then the auxiliary support plate 60 is flipped so that the second roller 61 abuts against the side wall of the pipe. Then, the height of the laser rust remover 10 is adjusted so that it is located at the pipe axis. Then, the second drive mechanism, the third drive mechanism, and the laser rust remover 10 are started, so that the laser rust remover 10 rotates and moves forward while removing rust from the inner wall of the pipe, thereby achieving comprehensive rust removal of the inner wall of the pipe. This eliminates the need for workers to use handheld rust removers, effectively avoiding the health and safety issues of workers during rust removal. At the same time, using the laser rust remover 10 to remove rust from the inner wall of the pipe can improve rust removal efficiency and reduce the generation of dust and impurities during the rust removal process, further avoiding the health and safety issues of workers during rust removal.

[0045] Example 2

[0046] According to the instruction manual Figure 8 As shown, in this embodiment, a fan 70 is also installed on the movable support 20. The fan 70 is located on the side of the movable support 20 away from the laser rust remover 10. The fan 70 enables air circulation inside the pipe, which on the one hand prevents the debris or impurities generated during the rust removal process from falling onto key components such as the rotating support 30 and the laser rust remover 10, thus preventing them from being damaged by impurities. On the other hand, it also balances the weight at both ends of the device, making its movement more stable.

[0047] Example 3

[0048] According to the instruction manual Figure 9 As shown, in this embodiment, a first camera 81 is installed on the rotating bracket 30, a second camera 82 is installed on the movable bracket 20, and a supplementary light 83 is installed on the movable bracket 20. The first camera 81 rotates together with the laser rust remover 10 to monitor the rust removal effect in real time, the second camera 82 monitors the overall rust removal effect to ensure excellent and stable rust removal effect, and the supplementary light 83 can illuminate the inside of the pipe to facilitate monitoring of the rust removal effect.
