[0002] Ductile iron pipe is a type of cast iron pipe, belonging to the category of metal pipes. It has excellent corrosion resistance and is mainly used for water supply, gas transmission, and oil transmission in municipal and industrial enterprises. If the required transmission length is long, ductile iron pipes need to be spliced ​​and installed.

[0003] The installation of ductile iron pipes is a process that requires precise operation, including cleaning the pipe openings to avoid the presence of foreign objects. Generally, the pipe openings are cleaned manually with a cloth. However, due to the large number of ductile iron pipes being installed, manual cleaning can easily lead to fatigue and is inefficient.

[0004] Therefore, we proposed auxiliary equipment for ductile iron pipe installation to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide auxiliary equipment for the installation of ductile iron pipes, so as to solve the problem mentioned in the background art that the current market uses rags to clean the openings of ductile iron pipes manually.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-7 The present invention provides the following technical solution: an auxiliary device for installing ductile iron pipes, including a mounting base 1, a support base 2 installed at the right end of the mounting base 1, a first spring 3 connected inside the support base 2, a moving rod 4 connected to the end of the first spring 3, a positioning groove 5 opened on the side of the moving rod 4 near the support base 2, a protrusion 6 connected to the side of the moving rod 4 away from the support base 2, and a roller 7 installed at the end of the moving rod 4 extending out of the support base 2.

[0028] Furthermore, the protrusions 6 are distributed at an angle on the side away from the moving rod 4, and the moving rod 4 is distributed at an equal angle about the transverse center line of the mounting base 1, so that the pipe opening contacts the protrusions 6 first, and smoothly presses the moving rod 4 to adapt to the diameter of the pipe opening for expansion and contraction.

[0029] A fixing plate 8 is installed on the outer wall of the mounting base 1. A second spring 9 is connected to the left side of the fixing plate 8. A moving ring 10 is connected to the end of the second spring 9. A positioning frame 11 is installed on the outer edge of the moving ring 10.

[0030] Furthermore, the movable ring 10 is sleeved on the outside of the mounting base 1, and there is a gap between the inner wall of the movable ring 10 and the outer wall of the mounting base 1 to ensure that the movable ring 10 moves smoothly and adjusts the position of the positioning frame 11.

[0031] Furthermore, the positioning frame 11 slides through the fixed plate 8 and the support base 2 in sequence, and the positioning frame 11 engages with the positioning groove 5, thereby limiting the movement rod 4 using the positioning frame 11;

[0032] A motor 12 is installed at the right end of the mounting base 1. A rotating rod 13 is connected to the output end of the motor 12. A connecting base 14 is installed at the left end of the rotating rod 13. An adjusting plate 22 passes through the inside of the connecting base 14. A limit frame 18 passes through the end of the adjusting plate 22. A mounting frame 15 is connected to the end of the limit frame 18. A cleaning cloth 17 is provided on the inner side of the mounting frame 15. Velcro 16 is connected to the opposite sides of the cleaning cloth 17 and the mounting frame 15.

[0033] Furthermore, the mounting bracket 15 has a side "U" shaped structure, and the mounting bracket 15 is connected to the cleaning cloth 17 by Velcro 16, which makes it easy to remove the cleaning cloth 17.

[0034] The end of the adjusting plate 22 is connected to a third spring 19, the end of the third spring 19 is connected to a limit seat 21, and one end of the limit seat 21 is connected to a connecting rod 20.

[0035] Furthermore, the side of the limiting seat 21 away from the adjusting plate 22 is inclined, and the other side of the limiting seat 21 engages with the limiting frame 18, which facilitates the assembly of the mounting frame 15.

[0036] Specifically, when using this ductile iron pipe to install auxiliary equipment, pressing the moving ring 10 to the left stretches and stores the second spring 9, and the moving ring 10 drives the positioning frame 11 to move to the left, moving the positioning frame 11 out of the positioning groove 5, releasing the lock on the moving rod 4. Then, the right end of the mounting base 1 can be gradually moved into the pipe opening of the ductile iron pipe. At this time, the pipe opening end contacts the protrusion 6, and the protrusion 6 can be pressed, thereby controlling the moving rod 4 to move into the support base 2, and the moving rod 4 compresses and stores the first spring 3 until the roller 7 moves into the ductile iron pipe and rolls along the inner wall of the ductile iron pipe, clamping the cleaning cloth 17 onto the inner and outer walls of the pipe opening. Releasing the pressure on the moving ring 10, the second spring 9 can then control the moving ring 10 to move to the right and reset, thereby controlling the positioning frame 11 to move to the right and reset, clamping the positioning frame 11 into the corresponding positioning groove 5. Figure 4 As shown, the moving rod 4 is locked to secure the position of the mounting base 1, thereby ensuring that the cleaning cloth 17 continues to be in contact with the tube opening;

[0037] The position of the mounting bracket 15 is adjustable. Remove the bolts fixing the adjusting plate 22 and the connecting seat 14, move the adjusting plate 22, and adjust the position of the mounting bracket 15 according to the diameter of the ductile iron pipes used in different batches, so that the cleaning cloth 17 can smoothly adhere to the pipe opening. After adjustment, lock the adjusting plate 22 and the connecting seat 14 with bolts. The two sets of mounting brackets 15 can be used alternately. The cleaning cloth 17 on one set of mounting brackets 15 cleans the pipe opening, while the other set can be disassembled for cleaning to ensure its working efficiency. Connect the motor 12 to the power supply, control the rotating rod 13 connected to the output end to rotate, thereby controlling the rotation of the connecting seat 14, which in turn causes the adjusting plate 22 to drive the mounting bracket 15 to rotate, allowing the cleaning cloth 17 to thoroughly clean the pipe opening. Press the connecting rod 20 away from the mounting bracket 15, and the connecting rod 20 drives the limiting seat 21 to move. At the same time, the limiting seat 21... The third spring 19 is pressed and stored, releasing the limiting seat 21 from limiting the limiting frame 18, thereby releasing the limiting of the mounting frame 15. The mounting frame 15 is pulled, and the limiting frame 18 is pulled out from the end of the adjusting plate 22. Then the cleaning cloth 17 is removed for cleaning. The mounting frame 15 is pushed directly, and the mounting frame 15 contacts the inclined surface of the limiting seat 21. The limiting seat 21 is pressed away from the mounting frame 15, and the limiting seat 21 presses and stores the third spring 19, so that the limiting frame 18 can smoothly pass through the adjusting plate 22. The mounting frame 15 is assembled to the end of the adjusting plate 22. The third spring 19 controls the limiting seat 21 to reset and move. The adjusting plate 22 is locked to the outside of the limiting frame 18, limiting it and realizing the installation of the mounting frame 15. The internal cleaning cloth 17 is then used to clean the pipe opening. The contents not described in detail in this specification are prior art known to those skilled in the art.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
