Description

Technical Field

[0001] This invention belongs to the field of rust removal technology, and in particular relates to a pipe rust removal device and construction method. Background Technology

[0002] In existing technologies, pipe rust removal methods mostly employ sandblasting or manual angle grinders. Sandblasting has several drawbacks: it requires large rust removal equipment, necessitates a large open space, lacks flexibility, and is costly. Manual angle grinder removal for small-diameter pipes requires workers to maintain a squatting posture while holding the grinder, resulting in flying rust dust that affects worker health and the surrounding environment, and also has low efficiency. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a pipe rust removal device and construction method, which is particularly suitable for efficient and environmentally friendly rust removal operations on small-diameter pipes. Compared with large-scale rust removal equipment, it can reduce the footprint of the device and improve the flexibility of use.

[0004] The technical solution adopted in this invention is: a pipe rust removal device, including a device base; a rust removal mechanism, which includes a first treatment part and a second treatment part arranged opposite to each other to treat the surface of the pipe, both the first treatment part and the second treatment part being rotatably connected to the device base; a protective cover, which covers the first treatment part and the second treatment part, the protective cover having an opening for the pipe to pass through and a flexible isolation member provided at the opening.

[0005] Furthermore, in the first processing unit and the second processing unit, at least one is slidably connected to the device base to adjust the distance between the two.

[0006] Furthermore, the rust removal mechanism also includes a pipe support assembly, which includes a mounting bracket connected to the device base and a tray movably connected to the mounting bracket, the tray being positioned below the first processing section and the second processing section.

[0007] Furthermore, the rotation axes of the first processing unit and the second processing unit are set at an angle.

[0008] Furthermore, pipe support structures are provided on both the pipe inlet and pipe outlet sides of the rust removal mechanism, and the pipe support structures have pipe swing limiting parts.

[0009] Furthermore, it also includes a dust collection mechanism, which is connected to a protective cover or device base and the suction port of the dust collection mechanism is connected to the internal space of the protective cover.

[0010] Furthermore, the rust removal mechanism also includes a first drive unit and a second drive unit connected to the device base, with the output end of the first drive unit connected to the first processing unit and the output end of the second drive unit connected to the second processing unit.

[0011] Furthermore, a reinforcing component is provided on the side of the first drive unit and / or the second drive unit. The reinforcing component includes a set screw support connected to the device base and a tightening member threadedly connected to the set screw support. The end of the tightening member is used to press against the first drive unit or the second drive unit.

[0012] Furthermore, the protective cover is connected to the device base, and the flexible isolation components are multiple curtain strips connected to the protective cover.

[0013] Furthermore, the present invention also provides a construction method for a pipeline rust removal device, comprising the following steps:

[0014] Start the rust removal mechanism to drive the first and second processing sections to rotate;

[0015] The pipe to be treated is inserted through an opening on one side of the protective cover and placed in the working area between the first treatment section and the second treatment section to remove rust from the pipe surface.

[0016] During the rust removal process, the pipe moves along its axis and exits through an opening on the other side of the protective cover, which works in conjunction with a flexible isolation element to limit the spread of rust dust.

[0017] The advantages and positive effects of this invention are as follows: due to the adoption of the above technical solution, efficient mechanical rust removal operations can be carried out on pipelines. The protective cover and flexible isolation components work together to effectively reduce the diffusion of rust dust to the external environment. It has the advantages of simple structure, reduced space occupation compared with large rust removal equipment, and strong practicality. Attached Figure Description

[0029] The embodiments of the present invention will now be described with reference to the accompanying drawings. The described embodiments are only some embodiments of the invention, and not all embodiments.

[0030] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar units or units having the same or similar functions throughout.

[0031] 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. In the description of the present invention, it should be understood that terms such as "installation," "connection," and "fixing" should be interpreted broadly, and can refer to direct connection, installation, or fixing, or indirect connection, installation, or fixing. The present invention does not impose any limitations in this regard.

[0032] It should be understood that the electrical connection relationship and control logic between the motor speed control switch and the corresponding fixed motor and movable motor, the power switch and the dust collection mechanism and each motor in this device are all implemented using conventional and mature circuit connection methods in this field. This is existing technology, so it will not be described in detail in this specification.

[0033] like Figure 1As shown, this is the traditional manual angle grinder rust removal method, which requires workers to work in a squatting position for a long time while holding the angle grinder. During the operation, rust dust flies around, affecting the health of workers and the surrounding environment, and the rust removal efficiency is low.

[0034] like Figures 2 to 9 The diagram shows an embodiment of a pipe rust removal device of the present invention, including a device base 1; a rust removal mechanism 2, which includes a first treatment section 21 and a second treatment section 22 disposed opposite to each other to treat the surface of a pipe 8, both the first treatment section 21 and the second treatment section 22 being rotatably connected to the device base 1; and a protective cover 3, which covers the first treatment section 21 and the second treatment section 22, the protective cover 3 having an opening for the pipe 8 to pass through, and a flexible isolation element 4 provided at the opening. Mechanical rust removal is achieved through the cooperation of the first treatment section 21 and the second treatment section 22, improving work efficiency; the protective cover 3, together with the flexible isolation element 4, effectively surrounds the rust removal area, preventing rust dust from splashing, improving the working environment, and creating conditions for dust collection. Preferably, the first treatment section 21 and the second treatment section 22 are wheel-shaped structures, and can be made of diamond grinding wheels.

[0035] In the first processing unit 21 and the second processing unit 22, at least one is slidably connected to the device base 1 to adjust the distance between them. The adjustable distance design increases the adaptability and flexibility of the device, allowing it to be used with pipes 8 of different diameters by adjusting the distance between the first processing unit 21 and the second processing unit 22, thus expanding the application range of the device.

[0036] The rust removal mechanism 2 also includes a pipe support assembly 23, which includes a mounting bracket connected to the device base 1 and a support plate 231 movably connected to the mounting bracket. The support plate 231 is positioned below the first processing section 21 and the second processing section 22. During commissioning or when the distance between the first processing section 21 and the second processing section 22 is large, the support plate 231 can support the pipe 8 from below, effectively reducing the risk of damage to the pipe 8 due to accidental falling to the ground, and improving operational safety and convenience.

[0037] The rotation axes of the first processing unit 21 and the second processing unit 22 are set at an angle, and the angle can be adjusted by those skilled in the art based on the working conditions and common technical knowledge. By using the axial force generated when the processing units rotate, the pipe 8 is automatically propelled forward without the need for additional power devices or manual pushing, thus realizing the automation and continuity of the rust removal process, improving work efficiency and reducing the physical exertion of personnel.

[0038] Pipe support structures 5 are provided on both the inlet and outlet sides of the rust removal mechanism. Each pipe support structure 5 has a pipe swing limiting part 51. Specifically, pipe support structures 5 are optionally provided on the front (inlet side) and rear (outlet side) sides of the rust removal mechanism 2 along the moving direction of the pipe 8. The pipe support structures 5 not only provide support for the pipe 8, but more importantly, guide and constrain the movement of the pipe 8, effectively preventing the pipe 8 from swinging during rust removal and automatic movement, and ensuring the stability and straightness of the rust removal process.

[0039] The pipeline rust removal device also includes a dust collection mechanism 6, which is connected to the protective cover 3 or the device base 1, and the suction port of the dust collection mechanism 6 is in communication with the internal space of the protective cover 3. The dust collection mechanism 6 can promptly remove rust dust generated inside the protective cover 3, further improving the working environment, and can also collect valuable metal dust.

[0040] The rust removal mechanism 2 also includes a first drive unit 24 and a second drive unit 25 connected to the device base 1. The output end of the first drive unit 24 is connected to the first processing unit 21, and the output end of the second drive unit 25 is connected to the second processing unit 22. Preferably, the first drive unit 24 and the second drive unit 25 can be drive motors, and the output shaft axis of the first drive unit 24 and the output shaft axis of the second drive unit 25 are set at an angle.

[0041] A reinforcing assembly 26 is provided on the side of the first drive unit 24 and / or the second drive unit 25. The reinforcing assembly 26 includes a set screw support 261 connected to the device base 1 and a clamping member 262 threadedly connected to the set screw support 261. The end of the clamping member 262 is used to abut against the first drive unit 24 or the second drive unit 25. The reinforcing assembly 26 can in particular compensate for the problem of insufficient fixing rigidity caused by using elongated holes to install the movable drive unit. The clamping member 262 provides additional lateral clamping force, which significantly enhances the stability of the movable motor during operation, ensuring the rust removal effect and equipment life.

[0042] The protective cover 3 is connected to the device base 1. The flexible isolation component 4 consists of multiple curtain strips connected to the protective cover 3, thereby creating a relatively closed working environment that facilitates the passage of the pipe 8. The flexible door curtain achieves a good balance between sealing and passage, with a reasonable structure and strong practicality.

[0043] In a specific embodiment:

[0044] The device base 1 includes two opposing raised bases 11 and a motor mounting base fixed to these two raised bases 11. The raised bases 11 are welded from structural steel and are used to raise the entire rust removal mechanism 2 to a suitable working height. The motor mounting base includes a first base 12 and a second base 13 arranged in parallel, which are connected by a connector 14 for reinforcement. The two ends of the first base 12 are respectively connected to the corresponding raised base 11, and similarly, the two ends of the second base 13 are respectively connected to the corresponding raised base 11, forming a stable overall structure.

[0045] The first processing unit 21 and the second processing unit 22 are diamond grinding wheels; the first drive unit 24 and the second drive unit 25 are drive motors, and in this embodiment, they are 220V threaded shaft speed-regulating motors. In this embodiment, the first drive unit 24 is fixed in position, and the second drive unit 25 is movable; in other embodiments, the first drive unit 24 is movable while the second drive unit 25 is fixed in position, or both the first drive unit 24 and the second drive unit 25 are movable. The fixed drive unit (first drive unit 24) is fixedly installed on the motor mounting base (such as the first base 12 and / or the second base 13) at a preset circular hole position by motor mounting bolts 29; the movable drive unit (second drive unit 25) is installed at a position corresponding to the elongated hole opened on the motor mounting base (first base 12 and / or the second base 13) and is also fixedly installed by motor mounting bolts 29, so that the distance between the second drive unit 25 and the first drive unit 24 is adjustable, thereby changing the distance between the first processing unit 21 and the second processing unit 22 (two grinding wheels) to adapt to pipes 8 of different diameters. Preferably, the first drive unit 24 and the second drive unit 25 have connecting seats for mounting motor fixing bolts 29. Both the first base 12 and the second base 13 have elongated holes for fixing the movable drive units. This design not only allows for the movable adjustment of some processing units but also facilitates the angled arrangement of the two processing units. The output shafts of the first drive unit 24 and the second drive unit 25 are reliably connected to their respective processing units (grinding wheels) via connecting components such as internal thread fixing flange 27 and external thread fixing flange 28.

[0046] To reduce the risk of the pipe 8 falling to the ground and being damaged due to excessive spacing between the first processing unit 21 and the second processing unit 22 during commissioning or under specific circumstances, a support plate 231 is installed below the first processing unit 21 and the second processing unit 22. The mounting bracket for installing the support plate 231 includes multiple sets of fixing plates (such as the first fixing plate 232 and the second fixing plate 233 forming a set installed on the first base 12 or the second base 13) respectively fixed to the first base 12 and the second base 13, and threaded rods mounted between the corresponding sets of fixing plates (such as the first threaded rod 234 connecting between the first fixing plate 232 and the second fixing plate 233 on the first base 12; and the second threaded rod 235 connecting between the first fixing plate 232 and the second fixing plate 233 on the second base 13). The two ends of the support plate 231 are respectively fitted onto the first threaded rod 234 and the second threaded rod 235, and the two sides of the support plate 231 are threadedly engaged with the threaded rods via adjusting nuts 236. By loosening the adjusting nut 236, the position of the support plate 231 on the lead screw can be adjusted; after adjustment, tightening the adjusting nut 236 will fix the support plate 231, allowing it to move and adjust effectively to support the support track 8.

[0047] The axis of the output shaft of the first drive unit 24 (first drive motor) and the axis of the output shaft of the second drive unit 25 (second drive motor) are not parallel, but have a specific angle. This angle design makes the two rotating processing units (grinding wheels) arranged at an angle. While removing rust from the surface of the pipe 8, it can generate an axial thrust on the pipe 8, thereby driving the pipe 8 to move automatically along its axis and realize continuous automated rust removal operation.

[0048] Along the working direction of the pipeline 8, pipeline support structures 5 are typically provided on both the front and rear sides of the pipeline rust removal mechanism 2. The pipeline support structure 5 includes a main body 52 and a pipeline swing limiting part 51 connected to the main body 52. ​​In this embodiment, the pipeline swing limiting part 51 is an inverted U-shaped frame structure connected to the main body 52. ​​The space formed between the U-shaped frame structure and the main body 52 allows the pipeline 8 to pass through, while its inner wall limits the pipeline 8 to prevent excessive swinging during movement. In another feasible embodiment, the pipeline swing limiting part 51 can also be a support member connected to the main body 52, with the top of the support member having an upward-opening curved surface, thus supporting the pipeline while preventing excessive swinging.

[0049] For the slidably adjustable second drive unit 25, although movement and initial fixation are achieved through elongated holes and motor fixing bolts 29, a reinforcing component 26 is added to the side of the second drive unit 25 to improve its stability during operation. The reinforcing component 26 includes a set screw support 261 fixed to a motor mounting base (such as the first base 12 and the second base 13), and a tightening member 262 (such as a bolt) threadedly connected to the set screw support 261. By tightening the tightening member 262, its end is tightly pressed against the connecting seat of the second drive unit 25, thereby providing additional lateral support and enhancing its stability in the working state. It is understood that in other embodiments, the reinforcing component 26 may also be simultaneously provided on the side of the first drive unit 24; its structure and reinforcement method will not be described further in this invention.

[0050] The protective cover 3 includes a main frame 31 mounted on the raised base 11, which encloses the main working areas (first processing section 21 and second processing section 22) of the rust removal mechanism 2. The main frame 31 is covered with a sealing plate, which consists of a surrounding plate 32, a front plate 33, and a rear plate 34, forming a protective space. This improves the sealing effect and reduces safety hazards for personnel compared to fully open operations. The surrounding plate 32 is made of sheet metal, fireproof canvas, or transparent acrylic sheet. It has a connecting hole for the dust collection mechanism. The front plate 33 and rear plate 34 are arranged sequentially along the direction of movement of the pipe 8. Both the front plate 33 and rear plate 34 are made of transparent acrylic sheet and have openings for the pipe 8 to pass through. The front plate 33 has mounting holes for the rust removal mechanism. To minimize the leakage of rust dust during the movement of the pipe 8, flexible seals are provided at the openings. In this embodiment, the flexible seals are multiple hanging curtain strips connected to the front plate 33 or the rear plate 34. The curtain strips are made of rubber or fireproof canvas. A dust collection mechanism 6 (e.g., a vacuum cleaner) is provided at the top of the protective cover 3 or at an appropriate position on the sealing plate. The suction pipe of the dust collection mechanism 6 extends into the main frame 31 of the protective cover 3 to connect the suction port of the dust collection mechanism 6 with the internal space of the protective cover 3, for timely absorption of rust dust generated during the rust removal process.

[0051] In addition, a switch mounting box 7 is installed on the device base 1 to house and protect the power switch 72 and the motor speed control switch 71. The power switch 72 is used to control the power supply to and from the entire device (including the drive unit and the dust collection mechanism 6); the motor speed control switch 71 is used to adjust the rotational speed of the corresponding first drive unit 24 or second drive unit 25 (for example, one motor speed control switch for each drive unit, corresponding to the first drive motor and the second drive motor respectively). The electrical connection method between the motor speed control switch 71, the power switch 72 and the corresponding control equipment is prior art and will not be described in detail here. By adjusting the rotational speed and direction of the two drive motors, the direction and speed of the automatic movement of the pipe 8 can be controlled. In this embodiment, the switch mounting box 7 is installed on the first base 12 or the second base 13.

[0052] On the other hand, the present invention also provides a construction method for a pipeline rust removal device, comprising the following steps:

[0053] The pipe rust removal equipment was transported to the vicinity of the small-diameter pipe storage area.

[0054] According to the diameter of the pipe 8 to be processed, adjust the position of the movable drive unit so that the distance between the first drive unit 24 and the second drive unit 25 is adapted to the diameter of the pipe 8, and lock it in place; adjust the position of the support plate 231 in the pipe support assembly 23 as needed.

[0055] Connect the power supply to the on-site distribution box and turn on the power switch to start the rust removal mechanism 2 and the dust collection mechanism 6. Adjust the speed and direction of the two drive motors to control the rotation of the first processing section 21 and the second processing section 22 (for example, make the speed of the movable motor about 3 times the speed of the fixed motor, and the specific multiple can be adjusted according to the movement direction and requirements of the pipeline 8).

[0056] One end of the pipe 8 to be treated is passed through the opening of the pipe support structure 5 and the front plate 33 of the protective cover 3 on one side, and placed in the working area between the first processing section 21 and the second processing section 22 to remove rust from the surface of the pipe 8.

[0057] During the rust removal process, pipe 8 is driven to move automatically along its axial direction. After rust removal, pipe 8 exits through the opening in the rear plate 34 of the protective cover 3 and moves to the pipe support structure 5 on the other side. The protective cover 3 cooperates with the flexible isolation element 4 to limit the spread of rust dust. The operator then performs follow-up work (such as stacking or painting).

[0058] This invention is particularly suitable for efficient and environmentally friendly rust removal operations on small-diameter pipes 8. Compared with large-scale rust removal equipment, it can reduce the footprint of the device and improve its applicability in various construction environments.

[0059] The embodiments of the present invention have been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
