Description

Technical Field

[0001] This utility model relates to the field of circular pipe cleaning technology, specifically a circular pipe inner wall cleaning device. Background Technology

[0002] A round pipe is a steel material with open ends and a hollow concentric circular cross-section. Its length is larger than its perimeter. The main uses of round pipes include pipelines, thermal equipment, machinery industry, oil and geological drilling, containers, chemical industry and special purposes. When cleaning the inner wall of a pipe, a round pipe inner wall cleaning device is required.

[0003] The round tube inner wall cleaning device uses a motor to drive the cleaning rod to rotate, which in turn drives the sandpaper flap wheel to rotate. The rotating sandpaper flap wheel can contact the inner wall of the round tube and rotate circumferentially, thus performing grinding and cleaning. However, the round tube cannot be placed stably during the cleaning process, which causes instability.

[0004] Therefore, we propose a novel device for cleaning the inner wall of circular tubes to solve the above-mentioned technical problems. Utility Model Content

[0034] Example 1

[0035] This embodiment provides a technical solution: a device for cleaning the inner wall of a circular tube, such as... Figures 1-6 As shown, it includes a positioning and grinding frame, a round tube body 5, an inner wall cleaning mechanism, a grinding moving mechanism, and a rolling collection box.

[0036] The cylindrical tube body 5 is installed and connected to both sides of the upper end of the positioning and grinding frame. The cylindrical tube body 5 can be stably positioned by the positioning and grinding frame, which effectively avoids shaking during cleaning. The inner wall cleaning mechanism is installed and connected to the inner side of the outer end of the cylindrical tube body 5. The inner wall cleaning mechanism can rotate and clean inside the cylindrical tube body 5. The grinding and moving mechanism is installed and connected to the upper end of the positioning and grinding frame, and can be stably positioned. The movable end of the grinding and moving mechanism is connected to the inner wall cleaning mechanism, and the grinding and moving mechanism can drive the inner wall cleaning mechanism to move and grind. The rolling collection box is installed and connected to the inner side of the left end of the positioning and grinding frame. The rolling collection box can be pulled out from the left end of the positioning and grinding frame, which facilitates the collection of cleaning debris.

[0037] The positioning and grinding machine frame includes a housing 7. The inner left side of the housing 7 has a storage cavity 43. A rolling collection box is installed in the housing 7 through the storage cavity 43, so that the rolling collection box can be installed accordingly. A double-headed telescopic cylinder 4 is installed on the inner upper side of the housing 7. The double-headed telescopic cylinder 4 is fixedly connected to the housing 7 by screw ear plates 41. The double-headed telescopic cylinder 4 can be stably placed on the housing 7 for telescopic movement. The telescopic rod end of the double-headed telescopic cylinder 4 is fixedly connected to an abutment pad 44. When the telescopic rod of the double-headed telescopic cylinder 4 is extended, it can drive the abutment pad 44 to move, thereby achieving abutment positioning. Pipe placement grooves 42 are opened on both sides of the upper end of the housing 7, which facilitates the placement of the round tube body 5.

[0038] The round tube body 5 is fitted into the pipe placement groove 42 at the upper end of the housing 7, so that it can be installed accordingly;

[0039] The double-headed telescopic cylinder 4 abuts against the round tube body 5 inside the pipe placement groove 42 through the abutment rubber pad 44, which can clamp it by abutting. The abutment rubber pad 44 can effectively increase the contact friction with the round tube body 5, so that the abutment fixation is more stable and firm.

[0040] like Figure 1 , Figure 3 and Figure 4 As shown, the rolling collection box includes a collection box body 6. The collection box body 6 has an impurity collection cavity 61 inside, which can collect the cleaned impurities. An outer handle 63 is installed in the middle of the outer end of the collection box body 6 by screws, which makes it easy for personnel to hold and pull it out, so that the collection box body 6 can be easily exposed to collect impurities. Rolling balls 62 are rotatably installed on the inner sides of both ends of the collection box body 6. The collection box body 6 makes rolling contact with the placement box 7 through the rolling balls 62. The rolling of the rolling balls 62 makes the collection box body 6 more flexible and convenient to pull out. The collection box 6 can receive impurities that fall from the inside of the round tube body 5 from right to left after cleaning.

[0041] During use, the round tube body 5 can be stably positioned by the positioning and grinding frame, which effectively avoids shaking during cleaning. The inner wall cleaning mechanism is installed and connected to the inner side of the outer end of the round tube body 5. The inner wall cleaning mechanism can rotate and clean inside the round tube body 5. The grinding and moving mechanism can drive the inner wall cleaning mechanism to move and grind. The rolling collection box is installed and connected to the inner side of the left end of the positioning and grinding frame. The rolling collection box can be pulled out from the left end of the positioning and grinding frame, which facilitates the collection of cleaning debris.

The output shaft of the first rotary motor 21, during rotation, can drive the second coupling 22 to rotate. A connecting rod is fixedly connected to the other end of the second coupling 22, which can then drive the connecting rod. The body rotates, and a third coupling 25 is fixedly connected to the other end of the connecting rod. The connecting rod can drive the third coupling 25 to rotate.

The other end of the first coupling 13 is fixedly connected to a connecting shaft 11. The first coupling 13 can change the position of the connecting shaft 11. The other end of the connecting shaft 11 is fixedly connected to a moving end plate 1. The connecting shaft 11 can change the position of the moving end plate 1. The lower inner side of the moving end plate 1 is fixedly connected to a fixed end plate 12. The moving end plate 1 can change the position of the fixed end plate 12. The fixed end plate 12 is fixedly connected to the transverse panel 2. The fixed end plate 12 can change the position of the transverse panel 2, so that the position can be changed for moving cleaning.

[0047] The maximum length of the telescopic rod of the electric telescopic cylinder 3 is greater than the length of the round tube body 5. When the electric telescopic cylinder 3 is extended, it can move from right to left for cleaning.
