Description

Technical Field

[0001] This utility model relates to the technical field of cleaning and degreasing equipment, and in particular to a precision steel pipe inner wall cleaning and degreasing equipment. Background Technology

[0002] The production process of precision steel pipes is the same as that of ordinary seamless pipes, except for an additional final pickling and cold rolling process. After the precision steel pipes are produced, impurities and oxides remain on the inner wall. To prevent these impurities and oxides from corroding the inner wall and to ensure the quality of the steel pipes, the inner wall of the precision steel pipes needs to be cleaned. However, the equipment currently used to clean the inner wall of precision steel pipes cannot quickly dry it after cleaning, resulting in water stains remaining in the inner cavity of the precision steel pipes. This can easily cause rust and corrosion on the inner wall of the precision steel pipes, reducing their quality and service life. Utility Model Content

[0003] This utility model discloses a precision steel pipe inner wall cleaning and degreasing device, which solves the problem that after cleaning the inner wall of precision steel pipe, the inner wall of precision steel pipe cannot be dried quickly, which easily causes rust and corrosion of the inner wall of precision steel pipe.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A precision steel pipe inner wall cleaning and degreasing device includes a support base, a top plate above the support base, an arc-shaped plate fixed to the top of the support base, and a movable plate and a sliding plate slidably connected to both sides of the top plate. A first connecting shell and a second connecting shell, which can be inserted into the steel pipe, are respectively provided on the opposite sides of the movable plate and the sliding plate. A nozzle and a spray head are respectively connected to the first connecting shell and the second connecting shell. Water supply pipes and air supply pipes for supplying water and air to the first connecting shell and the second connecting shell, respectively, are provided on the movable plate and the sliding plate. A cleaning cotton is detachably connected to the first connecting shell. A first electric telescopic rod and a second electric telescopic rod are respectively provided on the movable plate and the connecting plate for driving the first connecting shell and the second connecting shell to move relative to each other.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] After placing the steel pipe inside the arc-shaped plate, the placement and positioning of the steel pipe are completed. Then, the moving plate and sliding plate are moved so that the first and second connecting shells correspond to the two ends of the steel pipe, respectively. Then, the first electric telescopic rod is activated to drive the first connecting shell into the steel pipe. The water supply pipe is connected to an external water source. After the water supply pipe flows into the first connecting shell, the water is discharged through the nozzle on the first connecting shell, which can clean the inner wall of the steel pipe. With the repeated movement of the cleaning cotton, the inner wall of the steel pipe can be wiped clean. After the inner wall is cleaned, the No. 1 connecting shell is moved outside the steel pipe. Then, the No. 2 electric telescopic rod is activated to allow the No. 2 connecting shell to enter the steel pipe. The air supply pipe is connected to the external heater, and warm air is supplied into the No. 2 connecting shell. The warm air can then be discharged through the nozzle on the No. 2 connecting shell, quickly drying the inner wall of the steel pipe. This invention can quickly dry the cleaned inner wall of the steel pipe, avoiding water stains remaining in the inner cavity of the steel pipe, preventing subsequent rusting, and improving the quality and service life of the steel pipe.

[0013] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a precision steel pipe inner wall cleaning and degreasing device, including a support base 1, a top plate 2 above the support base 1, an arc-shaped plate 3 fixed to the top of the support base 1, and two slidably connected movable plates 4 and sliding plates 5 on the two sides of the top plate 2, which can move laterally. The opposite sides of the movable plates 4 and sliding plates 5 are respectively provided with a first connecting shell 41 and a second connecting shell 51 that can be inserted into the steel pipe. The first connecting shell 41 and the second connecting shell 51 are respectively connected to nozzles and spray heads. The movable plates 4 and sliding plates 5 are respectively provided with water supply pipes 74 and air supply pipes 58 for supplying water and air to the first connecting shell 41 and the second connecting shell 51. A cleaning cotton 42 is detachably connected to the first connecting shell 41. The movable plates 4 and sliding plates 5 are respectively provided with a first electric telescopic rod 43 and a second electric telescopic rod 52 for driving the first connecting shell 41 and the second connecting shell 51 to move relative to each other. After placing the steel pipe on the arc-shaped plate 3, the moving plate 4 and the sliding plate 5 are moved toward the steel pipe, so that the first connecting shell 41 and the second connecting shell 51 (both of which are circular) are aligned with the axis of the steel pipe. Then, the first electric telescopic rod 43 is activated to drive the first connecting shell 41 into the steel pipe. At the same time, an external water source enters the first connecting shell 41 through the water supply pipe 74 and is discharged through a set of nozzles on the first connecting shell 41 to rinse the inner wall of the steel pipe. Simultaneously, the cleaning cotton 42 is also flushed along with the first connecting shell 41. The movement of the first connecting shell 41 can scrub the inner wall of the steel pipe, cleaning away impurities and oxides adhering to it. After the inner wall of the steel pipe is cleaned, the first connecting shell 41 moves to the outside of the steel pipe, and then the second electric telescopic rod 52 is activated, driving the second connecting shell 51 into the steel pipe. At the same time, the air supply pipe 58 (both the water supply pipe 74 and the air supply pipe 58 are flexible hoses) delivers external warm air into the second connecting shell 51. After the warm air is discharged through a set of nozzles on the second connecting shell 51, the inner wall of the steel pipe can be quickly dried.

[0015] like Figure 1As shown, the bearing seat 1 has two sets of arc-shaped plates 3, which are distributed left and right, and each set of arc-shaped plates 3 is evenly distributed from front to back; a set of support plates 21 is fixed between the top plate 2 and the bearing seat 1, and each set of arc-shaped plates 3 has hydraulic rods 10 fixed on the support plates 21 on both sides. The telescopic end of the hydraulic rods 10 is fixed with a fixing plate 101, and a set of T-shaped plates 102 is fixed on the fixing plate 101. The set of T-shaped plates 102 and the set of arc-shaped plates 3 are staggered. After the steel pipe is placed inside a set of arc-shaped plates 3, the hydraulic rods 10 located on both sides of the set of arc-shaped plates 3 can be activated. The hydraulic rods 10 drive the T-shaped plates 102 to approach the steel pipe through the fixing plate 101. The two sets of T-shaped plates 102 can then cooperate to clamp the steel pipe, thus fixing it and preventing it from shaking during cleaning. Rubber pads are provided on the side of the T-shaped plate 102 that contacts the steel pipe, as well as on the inner wall of the arc-shaped plates 3, to increase the friction with the steel pipe. With the two sets of arc-shaped plates 3, when a steel pipe is placed inside a set of arc-shaped plates 3, the moving plate 4 can be moved to connect the first connecting shell 41 to the steel pipe. One end corresponds to the other, and then enters the steel pipe to clean the inside of the steel pipe. At the same time, the operator can place another steel pipe inside another set of arc plates 3. After the inner wall of the previous steel pipe is cleaned, the second connecting shell 51 can enter the cleaned steel pipe to air dry the inner wall of the steel pipe. The moving plate 4 moves towards the steel pipe to be cleaned so that when the cleaned steel pipe is air drying, the cleaning operation of another steel pipe can begin. There is no need to stop the machine for a long time to unload and load the steel pipe, which improves the cleaning efficiency of the steel pipe. The bottom of the T-shaped plate 102 is located below the bottom of the inner side of the arc plate 3.

[0016] like Figure 1 , Figure 2 and Figure 3As shown, a connecting post 44 is fixed on the first connecting shell 41, penetrating the axis of the cleaning cotton 42. A circular plate 45 is attached to the side of the cleaning cotton 42 away from the first connecting shell 41. A screw 46, threadedly connected to the connecting post 44, is fixed on the first circular plate 45. A connecting frame 7 is fixed to the telescopic end of the first electric telescopic rod 43. A connecting pipe 47 is connected to the side of the first connecting shell 41 away from the cleaning cotton 42. The connecting pipe 47 passes through the connecting frame 7 and is rotatably connected to the connecting frame 7. A motor 71 is fixed inside the connecting frame 7. A drive gear 72 is fixed on the shaft of the first motor 71. A driven gear 48 that meshes with the drive gear 72 is fixed on the connecting pipe 47. A fixed pipe 73, rotatably connected to one end of the connecting pipe 47, is fixed inside the connecting frame 7. A water supply pipe 74 is connected to the fixed pipe 73. After starting the No. 1 electric telescopic rod 43, the telescopic end of the No. 1 electric telescopic rod 43 can drive the connecting pipe 47 to move through the connecting frame 7, so that the connecting pipe 47 drives the No. 1 connecting shell 41 into the steel pipe; subsequently, the screw 46 and connecting post 44 can be disassembled, the No. 1 circular plate 45 can be removed, and then the cleaning cotton 42 can be removed for cleaning or replacement; when the cleaning cotton 42 is inside the steel pipe, the No. 1 motor 71 can be started to drive the driven gear 48 to rotate through the driving gear 72, and the driven gear 48 then... The connecting pipe 47 drives the first connecting shell 41 to rotate, so that the nozzle on the first connecting shell 41 can spray water evenly into the steel pipe. At the same time, the cleaning cotton 42 rotates and can further rub against the inner wall of the steel pipe to better wipe away impurities and oxides on the inner wall of the steel pipe, thus better cleaning the inner wall of the steel pipe. The water supply pipe 74 can discharge water into the fixed pipe 73, and the fixed pipe 73 can then distribute water into the connecting pipe 47, so that the water in the connecting pipe 47 enters the first connecting shell 41.

[0017] like Figure 2 and Figure 3 As shown, a connecting piece 6 is fixed on the connecting pipe 47 between the connecting frame 7 and the first connecting shell 41. A scraper 61 is fixed to the connecting piece 6 by bolts. After the scraper 61 is fixed to the connecting piece 6 by bolts, the scraper 61 enters the steel pipe and the end away from the connecting piece 6 contacts the inner wall of the steel pipe. Subsequently, when the connecting pipe 47 drives the scraper 61 to rotate, the tightly adhered impurities on the inner wall of the steel pipe can be scraped off.

[0018] like Figure 1 and Figure 4As shown, a disc 53 is fixed to the telescopic end of the second electric telescopic rod 52. A thin tube 54 connected to the second connecting shell 51 is fixed on the disc 53. An air supply pipe 58 is connected to the thin tube 54. A water-absorbing cotton 55 is provided on the side of the second connecting shell 51 away from the thin tube 54. A fixing post is fixed on the second connecting shell 51, penetrating the axis of the water-absorbing cotton 55. A second circular plate 56 is attached to the side of the water-absorbing cotton 55 away from the second connecting shell 51. A threaded post 57 connected to the fixing post is fixed on the second circular plate 56. The air supply pipe 58 delivers warm air to the second connecting shell 51 through the thin tube 54. After the second electric telescopic rod 52 is activated, the telescopic end of the second electric telescopic rod 52 can drive the thin tube 54 to move through the disc 53. The thin tube 54 then drives the second connecting shell 51 to move. The cleaning cotton 42 and the water-absorbing cotton 55 are both arranged in a ring. When the water-absorbing cotton 55 enters the steel pipe and comes into contact with the inner wall of the steel pipe, it can effectively absorb the water remaining in the steel pipe as the second connecting shell 51 moves, thus accelerating the drying efficiency of the inner wall of the steel pipe. When it is necessary to replace the water-absorbing cotton 55, the threaded post 57 can be separated from the fixed post, and the second circular plate 56 can be removed.

[0019] like Figure 1 , Figure 2 and Figure 4 As shown, the movable plate 4 and the sliding plate 5 are respectively provided with openings for the first electric telescopic rod 43 and the second electric telescopic rod 52 to pass through. The first automatic telescopic rod 8 and the second automatic telescopic rod 9 are respectively fixed on the movable plate 4 and the sliding plate 5. The telescopic ends of the first automatic telescopic rod 8 and the second automatic telescopic rod 9 are respectively fixed with the first lifting plate 81 and the second lifting plate 91 slidably connected in the openings. The first lifting plate 81 and the second lifting plate 91 are respectively fixed to the main body of the first electric telescopic rod 43 and the second electric telescopic rod 52. After activating the No. 1 automatic telescopic rod 8 and the No. 2 automatic telescopic rod 9, the No. 1 lifting plate 81 and the No. 2 lifting plate 91 can be driven to move up or down, so as to adjust the height of the No. 1 connecting shell 41 and the No. 2 connecting shell 51 according to the inner diameter of the steel pipe, so that the axis of the No. 1 connecting shell 41 and the No. 2 connecting shell 51 corresponds to the axis of the steel pipe. In addition, for steel pipes with different inner diameters, the cleaning cotton 42 and the water-absorbing cotton 55 can be disassembled and replaced with the corresponding ones. The diameter of the No. 1 connecting shell 41 and the No. 2 connecting shell 51 is adapted to the smallest inner diameter of the steel pipe. When cleaning the inner wall of the steel pipe with a larger inner diameter, it is not necessary to replace the No. 1 connecting shell 41 and the No. 2 connecting shell 51 because of the setting of the nozzle and spray head of the No. 1 connecting shell 41 and the No. 2 connecting shell 51.

[0020] like Figure 1As shown, two motors 13 are fixed to both sides of the top plate 2. Lead screws 131 are fixed to the shafts of the two motors 13, and the two lead screws 131 are threadedly connected to the moving plate 4 and the sliding plate 5, respectively. Slide tracks 11 are provided on both sides of the support base 1, and the two slide tracks 11 are slidably connected to the sliders on the moving plate 4 and the sliding plate 5, respectively. After starting the two motors 13, the two lead screws 131 rotate, allowing the moving plate 4 and the sliding plate 5 to move laterally. The slide tracks 11 increase the stability of the moving plate 4 and the sliding plate 5 during movement.

[0021] like Figure 1 As shown, the top of the support base 1 has a perforation, and the bottom of the support base 1 is fixed with a collection frame 12. The perforation on the support base 1 allows wastewater generated during steel pipe cleaning to pass through the perforation and enter the collection frame 12.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
