Description

Technical Field

[0001] This utility model belongs to the field of pipeline spraying technology, specifically relating to a pipeline repair spraying device. Background Technology

[0002] Pipeline repair spraying equipment is a specialized device used to repair defects in underground pipelines. Its core function is to uniformly coat the pipeline with anti-corrosion, anti-seepage, wear-resistant, or structural repair materials using high-pressure spraying technology, forming a protective or repair layer. This not only prevents media corrosion or leakage but is also suitable for repairing old cast iron and cement pipes. Through repair and protection, it can extend the service life of pipelines and reduce maintenance costs. Pipeline repair spraying equipment is widely used in municipal water supply and drainage pipelines, oil and gas pipelines, industrial pipelines, submarine pipelines, and trenchless repair projects.

[0003] Chinese Patent Publication No. CN222659060U relates to the field of spraying equipment technology, specifically disclosing a chemical pipeline anti-corrosion spraying device. The device includes a base, a linear guide rail on one side of the upper surface of the base, a movable seat slidably mounted on the linear guide rail, an adjusting groove penetrating the center of the base, two sets of stabilizing slides on both sides of the adjusting groove, two sets of movable plates slidably mounted within the adjusting groove and the two sets of stabilizing slides, two sets of grooves fixed to the upper surface of the movable plates, a rotating mechanism at the top of the grooves, and a movable slide block fixed to the center of the lower surface of the movable plates. The movable slide block slidably mounts within the adjusting groove, and a stabilizing bolt passes through the bottom of the groove. A spraying mechanism is mounted on one side of the upper surface of the movable seat, and a surface cleaning component is mounted on the other side of the upper surface of the movable seat. This invention can perform anti-corrosion spraying on chemical pipelines of different specifications, avoiding the impact of residual dust, stains, and rust on the outer surface of the chemical pipelines on the quality of the anti-corrosion spraying.

[0004] In actual use, to ensure repair quality, the present invention typically uses cleaning components to remove impurities from the pipeline surface. However, the cleaning components of pipeline repair spraying devices are often simply designed and only use simple cleaning rollers for cleaning. This cleaning method not only makes it difficult to completely remove various impurities from the pipeline surface, but also makes it easy for the removed impurities to re-adhere to the outer wall of the pipeline during the cleaning process, which in turn has an adverse effect on the overall repair efficiency and quality of the pipeline repair spraying device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1:

[0028] Please see Figure 1-4 This utility model provides a pipeline repair spraying device, comprising:

[0029] Base plate 1 and mounting bracket 2;

[0030] A fixing plate 3 is set on the upper end of the mounting frame 2, which is set on the upper end of the base plate 1. A storage box 4 is rotatably connected to the bottom end of the fixing plate 3. Multiple nozzles 5 are provided at the bottom end of the storage box 4.

[0031] Mounting frame 6 is set on the upper end of base plate 1. Mounting plates 7 are provided on both sides of the upper end of mounting frame 6. Both mounting plates 7 are rotatably connected to clamping plates 9 through mounting shaft 8.

[0032] The positioning frame 10 is located on the upper end of the base plate 1 and is located inside the mounting frame 6. The upper end of the positioning frame 10 is provided with a positioning bracket 11. The positioning bracket 11 is rotatably connected to the positioning shaft 12, and the outer side of the positioning shaft 12 is provided with a cleaning rod 13.

[0033] Specifically, such as Figure 3 As shown, the cleaning rod 13 has multiple rectangular grooves on its outer side, and multiple limiting springs 14 are provided in each of the multiple rectangular grooves. The other end of the multiple limiting springs 14 located on the same side is provided with the same cleaning brush 15 that is adapted to the rectangular groove. The multiple limiting springs 14 can restrict the position of the multiple cleaning brushes 15, so that the multiple cleaning brushes 15 can fit tightly against the pipeline surface, thereby improving the cleaning effect on the pipeline surface.

[0034] Specifically, such as Figure 3 As shown, a ventilation groove is provided inside the positioning shaft 12, and multiple dust suction holes 16 are provided on the side wall of the ventilation groove. The multiple dust suction holes 16 are arranged in a ring around the central axis of the positioning shaft 12, and one end of each of the multiple dust suction holes 16 passes through the ventilation groove and the cleaning rod 13.

[0035] Its design allows multiple suction holes 16 to fully absorb the cleaned impurities when the cleaning rod 13 rotates, which not only avoids affecting the operators and working environment, but also prevents secondary pollution of the cleaned pipeline, thus ensuring the quality of pipeline repair spraying.

[0036] Specifically, such as Figure 2 As shown, a matching air extraction pipe 17 is connected to one side of the ventilation slot, and a filter box 18 is provided at the other end of the air extraction pipe 17.

A filter plate 29 is provided inside the filter box 18. One end of the filter plate 29 passes through one side of the filter box 18 and extends to the outside. The filter plate 29 can be easily cleaned by removing the filtered impurities, thus ensuring the effect of filtering impurities.

The electric push rod 20 can adjust the height of the cleaning rod 13 and the multiple cleaning brushes 15 so that it can be adapted to pipelines of different sizes and specifications.

[0038] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the end of the mounting shaft 8 located on one side passes through the mounting plate 7 on one side and is provided with a mounting wheel 21. The side wall of the mounting plate 7 on one side is provided with a second motor 22. The second motor 22 is existing technology and will not be described in detail here. The output end of the second motor 22 is provided with a drive wheel 23 that meshes with the mounting wheel 21. When the second motor 22 is started, its output end will drive the drive wheel 23 to rotate. The drive wheel 23 will drive the mounting wheel 21 and the mounting shaft 8 on one side to rotate, thereby driving the pipeline to rotate, which can facilitate cleaning and spraying from different directions.

[0039] Example 2:

[0040] Please see Figure 1-4 This utility model provides a pipeline repair spraying device, comprising:

[0041] Base plate 1 and mounting bracket 2;

[0042] A fixing plate 3 is set on the upper end of the mounting frame 2. The mounting frame 2 is set on the upper end of the base plate 1. A storage box 4 is rotatably connected to the bottom end of the fixing plate 3. Multiple nozzles 5 are provided at the bottom end of the storage box 4.

[0043] Mounting frame 6 is set on the upper end of base plate 1. Mounting plates 7 are provided on both sides of the upper end of mounting frame 6. Both mounting plates 7 are rotatably connected to clamping plates 9 through mounting shaft 8.

[0044] The positioning frame 10 is located on the upper end of the base plate 1 and is located inside the mounting frame 6. The upper end of the positioning frame 10 is provided with a positioning bracket 11. The positioning bracket 11 is rotatably connected to the positioning shaft 12, and the outer side of the positioning shaft 12 is provided with a cleaning rod 13.

[0045] Specifically, such as Figure 1 and Figure 2 As shown, cylinders 24 are provided on both sides of the mounting frame 6. Cylinders 24 are existing technology and will not be described in detail here. The output ends of the two cylinders 24 are respectively located on one side of the two mounting plates 7. The two cylinders 24 can drive the two mounting plates 7 and the two clamping plates 9 to move respectively, so as to conveniently fix pipelines of different sizes and specifications, making the pipeline repair spraying device more applicable.

[0046] Specifically, such as Figure 2 As shown, a drive groove is provided in the base plate 1, and a threaded rod 25 is rotatably connected in the drive groove. Both sides of the threaded rod 25 are threadedly connected to a matching sliding sleeve 26. The upper ends of the two sliding sleeves 26 extend to the outside and are respectively set at the bottom ends of the two mounting plates 7. A third motor 27 is provided at one end of the base plate 1. The third motor 27 is existing technology and will not be described in detail here. One end of the threaded rod 25 extends to the outside and is set on the output end of the third motor 27.

[0047] Its design allows the threaded rod 25 to rotate, which in turn drives the two sliding sleeves 26 and the mounting frame 6 to move left and right. The mounting frame 6 can drive the two mounting plates 7 and the pipeline to move, thereby enabling multiple cleaning brushes 15 and multiple spray nozzles 5 to comprehensively repair and spray the pipeline.

[0048] See Figure 1-4When using the pipeline repair spraying device to repair and spray the pipeline, the pipeline first needs to be placed between two clamping plates 9, and then the two cylinders 24 are activated. The output ends of the two cylinders 24 will drive the two mounting plates 7 and the two clamping plates 9 to move respectively, thereby fixing the position of the pipeline. Then, the first motor 19 and the electric push rod 20 are activated. The output end of the first motor 19 will drive the positioning shaft 12 and the cleaning rod 13 to rotate, thereby driving multiple cleaning brushes 15 to rotate. The electric push rod 20 can adjust the height of the cleaning rod 13 and the multiple cleaning brushes 15 so that they can be pressed against the outside of pipelines of different sizes and specifications to clean the impurities on the outside of the pipeline.

[0049] When absorbing the impurities generated during cleaning, the air pump 28 needs to be started. The air pump 28 will draw air from the ventilation slot through the air extraction pipe 17 to create a negative pressure device, so that the cleaned impurities can be drawn into the filter box 18 through multiple dust suction holes 16, and the impurities are filtered by the filter plate 29 in the filter box 18.

[0050] When cleaning and spraying different locations on the pipeline, the second motor 22 and the third motor 27 need to be started. The output of the second motor 22 will drive the drive wheel 23 to rotate, which in turn drives the mounting wheel 21 and the mounting shaft 8 on one side to rotate, thereby driving the pipeline to rotate. The output of the third motor 27 will drive the threaded rod 25 to rotate, which will drive the mounting frame 6 to move through the two sliding sleeves 26. This allows for convenient repair spraying of different locations on the pipeline, making the pipeline repair spraying device more practical and convenient to use.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
