Description

Technical Field

[0001] This utility model relates to the field of pipe rust removal, and in particular to a pipe surface rust removal device. Background Technology

[0002] As an important industrial and building material, pipes are prone to oxidation and rust formation on their outer surface due to long-term exposure to air, requiring regular rust removal treatment. Currently, the main methods for removing rust from the outer surface of pipes include manual rust removal and mechanical rust removal. Manual rust removal mainly relies on operators using tools such as sandpaper and wire brushes for grinding, which is labor-intensive, inefficient, and results in uneven rust removal quality. Existing mechanical rust removal equipment, on the other hand, uses fixed grinding heads in some devices, requiring manual rotation of the pipe to achieve circumferential grinding, which also carries the risk of uneven grinding and makes it difficult to achieve comprehensive grinding of the outer wall of the pipe.

[0018] The first aspect of this utility model proposes a rust removal device for pipe surfaces, such as... Figure 1-6 As shown, it includes: a rust removal table 1 and symmetrically arranged chute 101 on the upper part of the rust removal table 1. The rust removal device also includes: Positioning components 2 are slidably installed in the slide groove 101, and a fixing component for supporting and positioning the inner wall of the pipe is provided between the bottom of the two positioning components 2 and the bottom of the rust removal table 1. A bracket 3 is fixed to the top of the rust removal table 1. A guide groove 301 is provided on the surface of the bracket 3, and a movable frame 4 is slidably installed on the guide groove 301. A drive component for driving the movable frame 4 to move along the length direction of the guide groove 301 is provided between one end of the movable frame 4 and the bracket 3. Rotary sleeve 5 is rotatably installed on the inner wall of the movable frame 4. At least one grinding block 6 for grinding the surface of the pipe is adjustablely installed inside the rotating sleeve 5. A gear ring 7 is fixedly installed on the outer wall of one end of the rotating sleeve 5. A gear 8 is meshed on the surface of the gear ring 7, and a first motor 9 for driving the gear 8 to rotate is connected to the gear 8. The first motor 9 is fixed on the movable frame 4.

[0019] When removing rust from the pipe surface, the pipe to be removed is first placed on the rust removal table 1. The distance between the two positioning parts 2 is adjusted by the fixing component so that the conical positioning end of the positioning part 2 is inserted into the inner wall of both ends of the pipe to achieve tight fixation. Then, the first motor 9 drives the gear 8 to rotate, so that the gear 8 meshes with the toothed ring 7 fixed on the outer wall of the rotating sleeve 5, thereby driving the grinding block 6 on the inner wall of the rotating sleeve 5 to rotate and grind the pipe. The driving component drives the rotating grinding block 6 to move, so as to achieve comprehensive grinding and rust removal treatment of the outer wall of the pipe.

[0020] In this embodiment: a dust cover 10 is fixedly installed on the outer wall of one side of the movable frame 4, and the dust cover 10 has a ring-shaped structure. The gear ring 7 and the gear 8 are both located inside the dust cover 10. The first motor 9 is fixedly installed on the outer wall of the dust cover 10, and the output end of the first motor 9 passes through the wall surface of the dust cover 10 and is fixedly connected to the center of the gear 8. The design of the dust cover 10 can effectively prevent dust generated during the grinding process from entering the transmission components, thereby extending the service life of the device.

[0021] In this embodiment, an annular groove is provided on the inner wall of the dust cover 10 corresponding to the installation position of the toothed ring 7. One end of the rotating sleeve 5 passes through the annular groove, and the toothed ring 7 is fixedly sleeved on the outer wall of the rotating sleeve 5 that passes through the annular groove. This structure ensures a stable connection between the rotating sleeve 5 and the toothed ring 7, while allowing the rotating sleeve 5 to rotate freely.

[0022] In this embodiment: the movable frame 4 has an annular structure adapted to the rotating sleeve 5, and the inner ring wall of the movable frame 4 and the outer ring wall of the rotating sleeve 5 are rotatably connected by a bearing. The inner ring of the bearing is fixedly connected to the surface of the rotating sleeve 5, and the outer ring of the bearing is fixedly connected to the inner wall of the movable frame 4 to ensure the smooth operation of the rotating sleeve 5.

[0023] In this embodiment: the fixing component includes: a first threaded sleeve 11 slidably installed inside the slide groove 101, the top of the first threaded sleeve 11 being fixedly connected to the bottom of the adjacent positioning member 2; A first lead screw 12 is rotatably installed at the bottom of the rust removal table 1. The surface of the first lead screw 12 is engaged with the internal thread of the first threaded sleeve 11. Both ends of the first lead screw 12 are threaded, and the threads at the left and right ends turn in opposite directions. Positioning sleeves are rotatably installed at both ends of the first lead screw 12, and the top of the positioning sleeves is fixedly installed at the bottom of the rust removal table 1. A rotating part is fixedly installed at one end of the first lead screw 12 to facilitate rotation of the first lead screw 12. When fixing the pipe, by rotating the first lead screw 12, the two first threaded sleeves 11 can be driven to move in opposite directions along the slide groove 101, thereby adjusting the distance between the two positioning parts 2 to adapt to pipes of different lengths and to tighten and fix the inner wall of the pipe.

[0024] In this embodiment, the positioning element 2 includes a connecting end and a positioning end fixed to the top of the connecting end. The bottom of the connecting end is fixedly connected to the top of the adjacent first threaded sleeve 11. The positioning end has a tapered structure and is used to insert into the end of the pipe and tighten and fix the inner wall of the pipe. The tapered structure of the positioning end facilitates insertion into the end of the pipe and achieves stable fixing of the pipe through the tightening force, preventing displacement during grinding.

[0025] In this embodiment: the drive assembly includes: a second threaded sleeve 14 slidably installed inside the guide groove 301, one side of the second threaded sleeve 14 being fixedly connected to the outer wall of the movable frame 4; The second lead screw 13, which is rotatably mounted on the bracket 3, is installed with the internal thread of the second threaded sleeve 14 in a mating manner. A second motor 15 is fixedly installed at one end of the bracket 3. The output end of the second motor 15 is fixedly connected to one end of the second lead screw 13 to drive the second lead screw 13 to rotate.

[0026] As the rotating sleeve 5 drives the grinding block 6 on the surface to rotate around the pipe, the second motor 15 works to drive the second lead screw 13 to rotate, which in turn drives the second threaded sleeve 14 and the moving frame 4 to move along the guide groove 301, so as to realize the feeding movement of the grinding block 6 along the axial direction of the pipe and ensure comprehensive rust removal.

[0027] In this embodiment: two grinding blocks 6 are provided, and the two grinding blocks 6 are symmetrically arranged on the inner wall of the rotating sleeve 5 along the axis of the rotating sleeve 5; The grinding block 6 is rotatably mounted with an adjusting bolt 601 on the side near the inner wall of the rotating sleeve 5 via a bearing, and the surface of the adjusting bolt 601 is threadedly fitted with the wall surface of the rotating sleeve 5. A guide rod 602 is symmetrically fixed on the side of the grinding block 6 near the inner wall of the rotating sleeve 5. The end of the guide rod 602 away from the grinding block 6 extends through to the outer wall of the rotating sleeve 5.

[0028] By rotating the adjusting bolt 601, the position of the grinding block 6 in the radial direction of the rotating sleeve 5 can be adjusted to accommodate pipes of different diameters. The guide rod 602 ensures the stability of the grinding block 6 during movement and improves the grinding accuracy.
