Description

Technical Field

[0001] The invention relates to the field of pipeline rust removal, and in particular to a rust removal robot. Background Art

[0002] Circular steel pipes are widely used in industrial production and construction, but steel is prone to rust and oxidation in the air, requiring regular rust removal and maintenance. Most factories today still use manual rust removal, which is not only inefficient and ineffective, but also creates a negative impact on worker health and safety risks. Rust removal robots have emerged as a response to this. However, existing rust removal robots can only polish undocked steel pipes. For pipes already installed in the wall, there are two ways to handle them. The first involves workers using a rust removal machine for manual polishing, which is limited by the site and results in low efficiency. The second involves disassembling the steel pipes and then using a rust removal robot to remove the rust. The repeated disassembly and installation of the steel pipes consumes a significant amount of manpower and material resources, resulting in low efficiency. Summary of the Invention

When both sides of the two semi-circular outer bodies are in the separated state, the two semi-circular outer bodies can be separated.

[0040] like Figure 2 and Figure 3 As shown, the walking drive mechanism includes a first support 16, a first driving motor 17, a driving wheel 18, a plurality of first driven walking components and a plurality of second driven walking components. A first waist-shaped hole is provided at the bottom of the first support 16.

A third groove is provided on one side of the snap base 41. The second pin 42 is provided on the snap base 41 and located in the third groove. One end of the snap 43 is rotatably sleeved on the second pin 42. The two ends of the spring 44 are respectively connected to the snap base 41 and one end of the snap 43. The other end of the snap 43 passes through two corresponding snap mounting holes 40 on the two second support plates 35 and can be snapped onto the other second support plate 35. In this embodiment, two second locking mechanisms are provided, one at the front and rear ends of the second support plate 35. Under the action of the spring 44, when the buckle 43 is connected to the other second support plate 35, the two second support plates 35 are in a locked and fixed state; when the two second support plates 35 need to be separated, the third nut 39 is first adjusted to make the two first support plates 34 able to rotate relative to each other, and the buckle 43 is pulled so that it is no longer connected to the second support plate 35. At this time, the buckle 43 squeezes the spring 44, and the other second support plate 35 is rotated so that the buckle 43 is disengaged from the buckle mounting hole 40 on the second support plate 35, thereby completing the separation of the two second support plates 35.

[0047] like Figure 1As shown, the rotation drive mechanism includes a fourth support 26, a second drive motor 27, a driving bevel gear 28 and a semi-ring bevel gear 29. A fourth waist-shaped hole is provided at the bottom of the fourth support 26. The fourth locking bolt is used to pass through the fourth waist-shaped hole to fix the fourth support 26 to the front side of a first semi-ring plate 1. The length direction of the fourth waist-shaped hole is consistent with the radial direction of the first semi-ring plate 1. The fourth locking bolt can also be used in conjunction with a nut to ensure that the fourth support 26 is firmly fixed. The second drive motor 27 is provided on the fourth support 26. The driving bevel gear 28 is fixedly sleeved on the power output shaft of the second drive motor 27. The axial direction of the driving bevel gear 28 is consistent with the radial direction of the first semi-ring plate 1. The semi-ring bevel gear 29 is fixed to the front side of a third semi-ring plate 30. The semi-ring bevel gear 29 can extend to the outside through the hole in the middle of the outer front cover, and the driving bevel gear 28 is meshed with the semi-ring bevel gear 29.

[0048] like Figure 15 As shown, the grinding device also includes a plurality of fifth supports 46. The grinder includes a support column 48 and a grinding disc 49 disposed at the rear end of the support column 48. The support column 48 is fixed to the fifth support 46. The supporting semi-annular plate 33 is provided with a fifth waist-shaped hole 45 and a mounting hole. A fifth locking bolt 47 is used to pass through the fifth waist-shaped hole 45 to thereby fix the fifth support 46 to the supporting semi-annular plate 33. The length direction of the fifth waist-shaped hole 45 is consistent with the radial direction of the supporting semi-annular plate 33. The fifth locking bolt 47 can also be used in conjunction with a nut to secure the fifth support 46. The grinding disc 49 is located in the semi-circular inner shell. The axial direction of the grinding disc 49 is consistent with the radial direction of the supporting semi-annular plate 33. The support column 48 extends through the mounting hole to the outside of the semi-circular inner shell. By adjusting the position of the fifth support 46, the radial position of the grinder can be adjusted, thereby enabling the grinding device to adapt to pipe bodies 200 of different outer diameters. In this embodiment, two fifth locking bolts 47 are provided on both sides of the fifth support 46 , and one fifth support 46 is installed in conjunction with four fifth waist-shaped holes 45 .

[0049] like Figure 4-Figure 7 As shown, the grinding device also includes a chip discharge tube 50 and multiple reinforcing support plates 51. The chip discharge tube 50 is arranged on the outside of a semi-cylindrical plate 32. The two ends of each reinforcing support plate 51 are respectively connected to a supporting semi-annular plate 33 and a third semi-annular plate 30. By arranging the reinforcing support plate 51, the connection between the semi-circular inner shell and the third semi-annular plate 30 is more firmly made.

[0050] like Figure 1As shown, the two ends of the tube body 200 are respectively fixed in the two walls 300. When in use, first adjust the fifth support 46 and the radial position of the grinder according to the outer diameter of the tube body 200, then install the grinding device on the tube body 200, tighten the third nut 39, so that the two first support plates 34 cannot rotate relative to each other, and make the buckle 43 clamped on the other second support plate 35, so that the two second support plates 35 are locked and fixed, thereby realizing the locking and fixation of the two semicircular inner bodies; then install the motion device, so that the front slide rail on the inner front cover contacts the multiple front pulleys 14, and the rear slide rail on the inner rear cover contacts the multiple rear pulleys 15, install the first bolt 7 and the first nut 8 on the two first locking plates 6, and install the second bolt and the second nut on the two second locking plates 9. At the same time, the locking rod 13 is rotated to make it engage in the second groove, thereby realizing the locking and fixation of the two semicircular outer bodies, and then the radial positions of the first support 16, the second support 19 and the third support 21 are adjusted according to the outer diameter of the tube body 200, so that the driving wheel 18, the first driven wheel 20 and the second driven wheel 24 are all in contact with the outer wall of the tube body 200; the first drive motor 17 and the second drive motor 27 are turned on, and the first drive motor 17 drives the driving wheel 18 to move, and the friction force between the driving wheel 18 and the tube body 200 drives the first driven wheel 20 and the second driven wheel 24 to move, so that the entire rust removal robot 100 performs axial movement on the tube body 200, and the grinding device rotates, the axial movement and the rotational movement are coordinated to make the grinding effect more uniform, and the grinding waste is discharged from the chip discharge pipe 50.

[0051] It can be seen that the movement device and the grinding device in this embodiment are both disassembled, and the tube body 200 does not need to be removed, and the installed tube body 200 can be directly ground. When in use, it is installed on the tube body 200 that has been put into use. The axial movement of the rust removal robot 100 on the tube body 200 is achieved by the walking drive mechanism, and the rotation drive mechanism drives the grinding device to rotate relative to the housing, thereby driving the grinder to grind and remove rust from the tube body 200. The rust removal robot 100 is easy to disassemble and install, can be recycled, realizes automatic grinding, has a fast grinding speed and uniform grinding, saves manpower, improves work efficiency, and is safe during use.
