Description

Technical Field

[0001] The utility model relates to the technical field of pipeline construction equipment, in particular to a pipeline cleaning device. Background Art

[0002] Underground pipelines are generally connected by passing the sub-pipes through the preset pipe holes. Before passing the sub-pipes through the pipe holes, the inside of the pipe holes needs to be cleaned to prevent the inside of the pipe holes from being blocked by debris, which makes it difficult for the sub-pipes to pass through.

[0003] At present, most people use metal rods plus wire brushes and miscellaneous cloth to clean the inner wall of the pipe hole. Although this simple device can achieve certain effects, when the metal rod is inserted into the pipe hole, the wire brush on the outside can easily push foreign matter deeper, making it difficult to remove the foreign matter, affecting the cleaning work and failing to improve the efficiency of pipeline construction.

[0030] Embodiment 1:

[0031] Combination Figures 1 to 4 As shown, this embodiment is a pipeline cleaning device, which is suitable for pipeline cleaning work in municipal engineering, including a cleaning cylinder 1, a scraper assembly, a cleaning assembly, a first drive assembly and a second drive assembly. The cleaning cylinder 1 includes a first cylinder body 11 and a second cylinder body 21. The scraper assembly includes a scraper plate 25. The cleaning assembly includes a cleaning cloth 14 and a support rod assembly. The first end of the first cylinder body 11 is a hand-held portion, and the second end of the first cylinder body 11 is provided with a support plate 12. The surrounding side of the support plate 12 is connected to the cleaning cloth 14. A support rod assembly is provided between the cloth surface of the cleaning cloth 14 and the outer wall of the first cylinder body 11. The first drive assembly is provided inside the first cylinder body 11. The first drive assembly is transmission-connected to the support rod assembly. The first drive assembly is used to drive the support rod assembly to drive the cleaning cloth 14 to achieve an extended state or a contracted state. The first barrel 11 is connected to the second barrel 21 via the support plate 12. A scraper plate 25 is movably provided at the end of the second barrel 21 away from the support plate 12. A second driving assembly is provided inside the second barrel 21. The second driving assembly is transmission-connected to the scraper plate 25. The second driving assembly is used to drive the scraper plate 25 and change its rotation angle.

[0032] When the support rod assembly drives the cleaning cloth 14 to achieve an extended state, the unfolded side of the cleaning cloth 14 abuts against the inner wall of the tube hole. When the support rod assembly drives the cleaning cloth 14 to achieve a contracted state, the cleaning cloth 14 closes and fits against the outer wall of the first tube body 11.

[0033] In some embodiments, the support rod assembly includes a first connecting rod 13, a second connecting rod 16 and a push ring 15, the outer wall of the first barrel 11 is slidably sleeved with the push ring 15, the push ring 15 is transmission-connected with the first driving assembly, and the first driving assembly can drive the push ring 15 to slide along the axial direction of the first barrel 11. The cloth surface of the cleaning cloth 14 is provided with first connecting rods 13 at intervals along the annular direction, the end of the first connecting rod 13 is hinged to the support plate 12, one end of the second connecting rod 16 is hinged to the outer wall of the push ring 15, and the other end of the second connecting rod 16 is hinged to the middle position of the first connecting rod 13, and a plurality of second connecting rods 16 are arranged circumferentially along the outer wall of the push ring 15.

[0034] Furthermore, four second connecting rods 16 are used in this embodiment.

[0035] In some embodiments, such as Figure 2 As shown, the first driving assembly includes a threaded rod 17, a threaded block 18 and a limit block 111. The threaded rod 17 is rotatably installed inside the first barrel 11 via a bearing. The threaded block 18 is threadedly installed on the outer wall of the threaded rod 17. The outer wall of the threaded block 18 is slidably connected to the inner wall of the first barrel 11. A limit groove 110 is axially provided on the outer wall of the first barrel 11. A slidable limit block 111 is provided in the limit groove 110. The limit block 111 is connected to the threaded block 18 toward the side wall of the threaded rod 17, and is connected to the push ring 15 toward the side wall of the push ring 15.

[0036] Furthermore, a knob 19 is rotatably mounted on the first end of the first barrel 11 , and the knob 19 is connected to the end of the threaded rod 17 .

[0037] By turning the knob 19, the knob 19 drives the threaded rod 17 to rotate around its own axis. Since the threaded rod 17 is threadedly connected to the threaded block 18, and the limit block 111 cooperates with the limit groove 110 to limit the threaded block 18, the threaded block 18 can only move linearly inside the first barrel 11, so that the limit block 111 drives the push ring 15 to slide along the axial direction of the first barrel 11. According to the different rotation directions of the knob 19, the limit block 111 drives the push ring 15 to slide in different directions. The push ring 15 synchronously drives the second connecting rod 16 to swing back and forth, and the second connecting rod 16 supports the first connecting rod 13, so that the cleaning cloth 14 is in an extended state when opened or in a contracted state when closed.

[0038] In some embodiments, such as Figure 3 and Figure 4As shown, the second driving assembly includes a rotating shaft 23, a gear 24, a toothed plate 26 and an electric telescopic rod 27. The second barrel 21 is provided with a groove 22 at the end away from the support plate 12. The rotating shaft 23 is rotatably mounted in the groove 22 via a bearing. The rotating shaft 23 is sleeved with a gear 24, and the gear 24 is fixedly connected to a scraper plate 25. The electric telescopic rod 27 is fixedly mounted inside the second barrel 21. The output end of the electric telescopic rod 27 is connected to a toothed plate 26 that can slide axially along the second barrel 21, and the side wall of the toothed plate 26 is meshed with the gear 24.

[0039] Furthermore, the grooves 22 at the ends of the second barrel 21 are arranged symmetrically, and the two grooves 22 are symmetrically provided with the rotating shaft 23, the gear 24 and the scraper plate 25, and the two sides of the tooth plate 26 are meshed with the corresponding gears 24.

[0040] By starting the electric telescopic rod 27, the electric telescopic rod 27 drives the tooth plate 26 to slide axially along the second barrel 21. Due to the meshing action of the tooth plate 26 and the gear 24, the telescopic action of the tooth plate 26 drives the gear 24 to rotate, so that the gear 24 drives the connected scraper plate 25 to rotate. The electric telescopic rod 27 provides power for the rotation of the gear 24, and then the rotation angle of the scraper plates 25 on both sides is adjusted.

[0041] Embodiment 2:

[0042] This embodiment is a method for using a pipeline cleaning device, comprising the following steps:

[0043] First, keep the cleaning cloth 14 closed, the cleaning cloth 14 is in a contracted state and fits against the outer wall of the first tube body 11, and keep the scraper plate 25 in a folded state and fits against the outer wall of the second tube body 21;

[0044] Then, the cleaning cylinder 1 is inserted into the pipe hole until it is located at the bonding block, and the electric telescopic rod 27 is started to push the tooth plate 26 to move. Due to the meshing action between the tooth plate 26 and the gear 24, the tooth plate 26 drives the gear 24 to rotate, and the gear 24 correspondingly drives the scraper plate 25 to rotate, so that the angles of the scraper plates 25 on both sides are changed, and the scraper plates 25 are controlled to maintain a vertical state with the inner wall of the pipe hole, and the scraper plates 25 are attached to the inner wall of the pipe hole. The operator can drive the scraper plates 25 to scrape the inner wall of the pipe hole by pulling the cleaning cylinder 1 back and forth;

[0045] When the scraping work is finished, the knob 19 is turned, and the knob 19 drives the threaded rod 17 to rotate. Since the threaded rod 17 is threadedly connected to the threaded block 18, and the threaded block 18 is limited by the limit groove 110 and the limit block 111, the rotation of the knob 19 drives the limit block 111 to slide in the limit groove 110, and the limit block 111 simultaneously drives the push ring 15 to slide toward the support plate 12 side, and the push ring 15 drives the first connecting rod 13 and the second connecting rod 16, so that the first connecting rod 13 and the second connecting rod 16 cooperate to gradually open the cleaning cloth 14, and the peripheral edge of the cleaning cloth 14 is attached to the inner wall of the pipe hole, and then the cleaning tube 1 is pulled out. At this time, the opened cleaning cloth 14 will simultaneously bring debris out of the pipe hole.

[0046] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
