Description

Technical Field

[0001] This utility model belongs to the technical field of pipeline processing, specifically a device for grinding and cleaning the inner and outer walls of steel pipes. Background Technology

[0002] Surface treatment is a crucial step in the production, processing, and maintenance of steel pipes. Whether it's removing welding burrs and oxide scale, or improving surface smoothness to meet the requirements of corrosion protection, painting, or precision assembly, the grinding process of both the inner and outer walls is essential. Traditional manual grinding is inefficient and inconsistent, making it difficult to meet the needs of industrialized mass production. However, the emergence of steel pipe inner and outer wall grinding devices, through mechanized and automated design, has achieved efficient and precise surface treatment, becoming one of the core equipment in the modern steel pipe processing field.

[0003] Existing steel pipe internal and external wall grinding devices have certain shortcomings in use. When grinding the outer wall of a steel pipe, the grinding operation is completed by the rotation and movement of the grinding wheel on the outer wall of the steel pipe, in conjunction with the rotation of the steel pipe itself. However, when grinding the inner wall of a steel pipe, the grinding wheel needs to be inserted into the inside of the steel pipe for grinding. Grinding the inner and outer walls of steel pipes usually requires the use of two sets of grinding wheels, and it is impossible to complete the grinding of the inner and outer walls separately with a single grinding structure. Secondly, different models of steel pipes have different lengths and diameters, and traditional grinding devices cannot flexibly adapt to different models of large-diameter steel pipe structures, which reduces their applicability.

[0004] In summary, existing steel pipe inner and outer wall grinding devices cannot complete the grinding of the inner and outer walls of steel pipes separately using a single grinding structure. They have poor flexibility and cannot be flexibly applied to large-diameter steel pipe structures of different specifications, thus reducing their applicability. Utility Model Content

[0005] This utility model provides a steel pipe inner and outer wall grinding and cleaning device, which can solve the problem that the existing steel pipe inner and outer wall grinding devices cannot complete the grinding of the inner and outer walls of the steel pipe separately through a single grinding structure, resulting in poor flexibility and inability to flexibly apply to large-diameter steel pipe structures of different specifications, thus reducing its applicability.

[0006] A steel pipe inner and outer wall grinding and cleaning device includes a grinding box and a drive base. The drive base is movably installed at one end of the grinding box. The grinding box and the drive base are movably connected by a transverse slide rod. A rotating rod is movably installed at one end of the drive base, and a grinding wheel for grinding the pipe body is fixedly installed at the end of the rotating rod. The outer surface of the rotating rod and the grinding box are movably connected by a lifting slider. Two sets of inclined slide seats are movably installed at the lower side of the grinding box. A limit slide seat is fixedly installed at one end of the inclined slide seat. The limit slide seat is slidably installed inside the grinding box, and two sets of triangular brackets for supporting the pipe body are movably installed on the upper outer surface of the limit slide seat.

[0007] As a further technical solution of this utility model, the two sets of triangular brackets are symmetrically arranged, and a limiting chuck is movably installed on one side of the triangular bracket. The user can adjust the position of the two sets of limiting slides according to the length of the tube, place the tube inside the grinding box, and make the tube stuck between the two sets of triangular brackets of the limiting slide. The triangular bracket can limit the tube when it rotates by means of the limiting chuck.

[0008] As a further technical solution of this utility model, a drive wheel is movably installed at the upper middle position of the limiting slide. The drive wheel is driven by a motor and contacts the bottom of the tube. The drive wheel can drive the tube to rotate.

[0009] As a further technical solution of this utility model, a movable clamping plate is movably installed on the lower part of the triangular card holder, and a slide rail is provided inside the limiting slide block to cooperate with the movable clamping plate. When the triangular card holder moves to the corresponding position, the movable clamping plate is driven to move by the screw, so that the slide rail is locked between the two sets of movable clamping plates, thus completing the fixing operation of the triangular card holder.

[0010] As a further technical solution of this utility model, an electric motor for driving the rotating rod is movably installed inside the drive seat. The electric motor and the drive seat are movably connected by a vertical slide rod. The electric motor moves up and down along the vertical slide rod, which can adjust the height of the rotating rod and the grinding wheel. When grinding the outer wall of the tube, the grinding wheel is moved to the outer wall of the tube. The electric motor drives the rotating rod, which in turn drives the grinding wheel to rotate. The drive seat pushes the rotating rod and the grinding wheel forward. During the rotation of the tube, the grinding process of the inner or outer wall of the tube is completed.

[0011] As a further technical solution of this utility model, the upper end of the motor and the drive seat are driven by a second lead screw, and the lower end of the second lead screw and the top end of the motor are movably connected by a shaft. The lower ends of the second lead screw and the first lead screw are both non-threaded structures, and the second lead screw and the drive seat are threadedly connected. When the second lead screw rotates, the operating height of the motor can be adjusted by the up and down movement of the second lead screw.

[0012] As a further technical solution of this utility model, a first lead screw is movably installed at the upper end of the lifting slider. The lifting slider and the grinding box are driven by the first lead screw. When the rotating rod is in use, the lifting slider plays an auxiliary support role for the rotating rod. At the same time, the height of the lifting slider can be adjusted by the first lead screw. The lifting slider and the rotating rod are movably connected.

[0013] As a further technical solution of this utility model, a side-rotating cover plate is movably installed on one side of the grinding box, and a caster is movably installed at the bottom of the drive seat. After the tube body has been ground, the side-rotating cover plate is opened, the tube body is lifted upward, and the tube body can be discharged to one side through the inclined slide.

[0014] As a further technical solution of this utility model, a rinsing slide is movably installed on the upper outer surface of the grinding box. Several sets of nozzles are provided at the bottom of the rinsing slide. The rinsing slide is connected to the cleaning fluid, and the cleaning fluid can be sprayed downward through the nozzles to clean the rust on the surface of the pipe.

[0015] As a further technical solution of this utility model, the upper end of the grinding box is provided with a sliding groove for use with the rinsing sliding sleeve, and the upper outer surface of the inclined sliding seat is an inclined structure.

[0016] The beneficial effects of this utility model are as follows: By setting a drive seat and a lifting slider, this utility model allows for the grinding and cleaning of the inner and outer walls of the steel pipe. By adjusting the vertical position of the grinding wheel and coordinating it with the lateral movement of the grinding wheel itself, the grinding structure can be used to grind both the inner and outer walls of the pipe. During operation, the motor moves up and down along the vertical slide bar, adjusting the height of the rotating rod and the grinding wheel. When grinding the outer wall of the pipe, the grinding wheel is moved to the outer wall, and the motor drives the rotating rod, causing the rotating rod to rotate the grinding wheel. The moving seat pushes the rotating rod and grinding wheel forward, completing the grinding of the outer wall of the pipe during its rotation. When the second lead screw rotates, its vertical movement adjusts the operating height of the motor. For grinding the inner wall of the pipe, the grinding wheel is moved to the inner wall. When the rotating rod is in use, the lifting slider provides auxiliary support, and the height of the lifting slider can be adjusted using the first lead screw to improve the stability of the rotating rod. The driving seat pushes the driving seat, causing it to move the grinding wheel laterally, completing the grinding of the inner or outer wall of the pipe during its rotation.

[0017] By setting limit slides and triangular clamps, this steel pipe inner and outer wall grinding and cleaning device can be flexibly applied to different types of pipe structures, thus expanding its applicability. Users can adjust the positions of the two sets of limit slides according to the length of the pipe, place the pipe inside the grinding box, and let the pipe be clamped between the two sets of triangular clamps of the limit slides. The triangular clamps can limit the rotation of the pipe by using limit rollers. The drive wheel can drive the pipe to rotate. When the triangular clamps move to the corresponding position, the screw drives the moving clamp to move, so that the slide rail is clamped between the two sets of moving clamps, completing the fixing operation of the triangular clamps. The triangular clamps play a limiting role on both sides of the pipe. Attached Figure Description

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] like Figures 1-4 As shown, a steel pipe inner and outer wall grinding and cleaning device includes a grinding box 2 and a drive seat 5. The drive seat 5 is movably installed at one end of the grinding box 2. The grinding box 2 and the drive seat 5 are movably connected by a transverse slide rod 4. A rotating rod 8 is movably installed at one end of the drive seat 5, and a grinding wheel 9 for grinding the pipe body 11 is fixedly installed at the end of the rotating rod 8. The outer surface of the rotating rod 8 and the grinding box 2 are movably connected by a lifting slider 7. Two sets of inclined slide seats 3 are movably installed at the lower side of the grinding box 2. A limiting slide seat 12 is fixedly installed at one end of the inclined slide seat 3. The limiting slide seat 12 is slidably installed inside the grinding box 2, and two sets of triangular brackets 14 for supporting the pipe body 11 are movably installed on the upper outer surface of the limiting slide seat 12.

[0026] Pipe body 11 is a seamless steel pipe, model GB / T8162-2018, with an outer diameter of 325mm and a wall thickness of 16mm;

[0027] The two sets of triangular brackets 14 are symmetrically arranged. A limiting wheel 16 is movably installed on one side of the triangular bracket 14. The user can adjust the position of the two sets of limiting slides 12 according to the length of the tube 11, place the tube 11 inside the grinding box 2, and make the tube 11 lock between the two sets of triangular brackets 14 of the limiting slide 12. The triangular brackets 14 can limit the tube 11 when it rotates through the limiting wheel 16.

[0028] A drive wheel 13 is movably installed at the upper middle position of the limit slide 12. The drive wheel 13 is driven by a motor and contacts the bottom of the tube body 11. The drive wheel 13 can drive the tube body 11 to rotate.

[0029] The lower part of the triangular bracket 14 is movably mounted with a movable clamping plate 17. The interior of the limiting slide 12 is provided with a slide rail that works in conjunction with the movable clamping plate 17. When the triangular bracket 14 moves to the corresponding position, the movable clamping plate 17 is moved by the lead screw, so that the slide rail is locked between the two sets of movable clamping plates 17, thus completing the fixing operation of the triangular bracket 14.

[0030] The drive base 5 houses a motor 15 for driving the rotating rod 8. The motor 15 and the drive base 5 are movably connected by a vertical slide rod 18. The motor 15 moves up and down along the vertical slide rod 18 to adjust the height of the rotating rod 8 and the grinding wheel 9. When grinding the outside of the tube 11, the grinding wheel 9 is moved to the outer wall of the tube 11. The motor 15 drives the rotating rod 8, causing the rotating rod 8 to rotate the grinding wheel 9. The drive base 5 then pushes the rotating rod 8 and the grinding wheel 9 forward. During the rotation of the tube 11, the grinding process on the inner or outer wall of the tube 11 is completed.

[0031] The upper end of the motor 15 is driven by the second lead screw 19 to the drive seat 5. The lower end of the second lead screw 19 is movably connected to the top end of the motor 15 by a shaft. The lower ends of the second lead screw 19 and the first lead screw 6 are both non-threaded structures. The second lead screw 19 and the drive seat 5 are threaded together. When the second lead screw 19 rotates, the working height of the motor 15 can be adjusted by the up and down movement of the second lead screw 19.

[0032] The upper end of the lifting slider 7 is movably mounted with a first lead screw 6. The lifting slider 7 and the grinding box 2 are driven by the first lead screw 6. When the rotating rod 8 is in use, the lifting slider 7 provides auxiliary support for the rotating rod 8. At the same time, the height of the lifting slider 7 can be adjusted by the first lead screw 6. The lifting slider 7 and the rotating rod 8 are movably connected.

[0033] A side-rotating cover plate 1 is movably installed on one side of the grinding box 2, and casters are movably installed on the bottom of the drive seat 5. After the tube body 11 has been ground, the side-rotating cover plate 1 is opened, the tube body 11 is lifted upward, and the tube body 11 can be discharged to one side through the inclined slide 3.

[0034] A flushing sleeve 10 is movably installed on the upper outer surface of the grinding box 2. Several sets of nozzles are provided at the bottom of the flushing sleeve 10. The cleaning fluid is connected to the flushing sleeve 10 and can be sprayed downward through the nozzles to clean the rust on the surface of the pipe body 11.

[0035] The upper end of the grinding box 2 is provided with a sliding groove for use with the flushing sliding sleeve 10, and the upper outer surface of the inclined sliding block 3 is an inclined structure.

[0036] A steel pipe inner and outer wall grinding and cleaning device, in use, by setting up a drive seat 5 and a lifting slider 7, can grind the inner and outer walls of the pipe separately by adjusting the vertical position of the grinding wheel 9 and moving the grinding wheel 9 itself in conjunction with the vertical position adjustment of the grinding wheel 9. During operation, the motor 15 moves up and down along the vertical slide rod 18 to adjust the height of the rotating rod 8 and the grinding wheel 9. When grinding the outer wall of the pipe body 11, the grinding wheel 9 is moved to the outer wall of the pipe body 11, and the motor 15 drives the rotating rod 8, causing the rotating rod 8 to drive the grinding wheel 9 to rotate. The moving seat 5 pushes the rotating rod 8 and the grinding wheel 9 forward, completing the grinding process on the outer wall of the pipe 11 during its rotation. When the second lead screw 19 rotates, its vertical movement adjusts the operating height of the motor 15. During the inner wall grinding operation, the grinding wheel 9 is moved to the inner wall of the pipe. When the rotating rod 8 is in use, the lifting slider 7 provides auxiliary support. Simultaneously, the height of the lifting slider 7 can be adjusted using the first lead screw 6 to improve the stability of the rotating rod 8 during use. This pushes the drive seat 5, causing it to move the grinding wheel 9 laterally, completing the grinding process on the inner or outer wall of the pipe during its rotation.

[0037] By setting the limiting slide 12 and the triangular clamp 14, the steel pipe inner and outer wall grinding and cleaning device can be flexibly applied to different types of pipe structures, thus expanding its applicability. The user can adjust the position of the two sets of limiting slides 12 according to the length of the pipe body 11, place the pipe body 11 inside the grinding box 2, and make the pipe body 11 clamp between the two sets of triangular clamps 14 of the limiting slide 12. The triangular clamp 14 can limit the pipe body 11 when it rotates through the limiting clamp wheel 16. The drive wheel 13 can drive the pipe body 11 to rotate. When the triangular clamp 14 moves to the corresponding position, the moving clamp 17 is moved by the screw, so that the slide rail is clamped between the two sets of moving clamps 17, completing the fixing operation of the triangular clamp 14. The triangular clamp 14 plays a limiting role on both sides of the pipe body 11.

[0038] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
