Description

Technical Field

[0001] This utility model belongs to the field of concrete conveying technology, and in particular relates to a cleaning nozzle device for concrete conveying pipelines. Background Technology

[0002] Concrete conveying pipelines are tubular structures used to transport ready-mixed concrete from the mixing equipment to the pouring site during concrete construction. They are usually made of high-strength steel, such as seamless steel pipes, and have good compressive strength and wear resistance, and can withstand the high pressure of concrete during pumping and friction with the pipe wall.

[0003] After use, concrete conveying pipelines often have a large amount of concrete residue left on their walls. If this residue is not cleaned in time, it will affect the pipeline's next use, reduce its conveying efficiency, and may even cause blockages, shortening its service life. High-pressure flushing is not effective at cleaning stubborn concrete residue on the pipe walls. Therefore, it is necessary to provide concrete conveying pipeline cleaning nozzle devices that use high-pressure impact combined with physical force to effectively clean stubborn concrete residue on the pipe walls, thereby reducing flushing time and speeding up the cleaning process. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning nozzle device for concrete conveying pipelines, which uses high-pressure impact combined with physical force to effectively clean stubborn concrete residues adhering to the pipe wall, thereby reducing rinsing time and accelerating cleaning speed, thus solving the above-mentioned technical problems.

[0020] In the following description, embodiments of the concrete conveying pipeline cleaning nozzle device of the present invention will be described with reference to the accompanying drawings.

[0021] Figure 1-4 This invention illustrates a concrete conveying pipeline cleaning nozzle device according to an embodiment of the present invention, comprising a rotating tube 1; a nozzle 2 communicating with its inner cavity is fixedly connected to the front end of the rotating tube 1; a conical surface is provided on the left side of the nozzle 2; multiple spray holes 6 communicating with its inner cavity are opened on the surface of the nozzle 2; a rotating hose 10 communicating with its inner cavity is fixedly connected to the right end of the rotating tube 1; a rotatable sleeve 7 is fitted on the surface of the rotating hose 10; an adjusting sleeve 3 is fitted on the right side of the surface of the rotating tube 1; and a dredging component 4 is provided on the surface of the adjusting sleeve 3. The device includes three ear plates 41 fixedly connected to the surface of the nozzle 2 and arranged in a ring. A steel chain 42 passes through the inner cavity of the ear plate 41. Three U-shaped lock heads 43 arranged in a ring are fixedly connected to the surface of the adjusting sleeve 3. The end of the steel chain 42 away from the ear plate 41 is engaged in the inner cavity of the U-shaped lock head 43. A limit pin 44 is inserted into the inner cavity of the U-shaped lock head 43. One end of the surface of the limit pin 44 has an insertion hole 8. An insert 9 is inserted into the inner cavity of the insertion hole 8. Through the cooperation of the insertion hole 8 and the insert 9, the limit pin 44 is locked, thus limiting and locking the limit pin 44. 4 can be stably inserted into the inner cavity of the U-shaped lock head 43, thereby making the U-shaped lock head 43 stably connected to the steel chain 42. The limiting pin 44 is inserted into the inner cavity of the steel chain 42. The surface of the rotating tube 1 is provided with an adjusting component 5. The adjusting component 5 includes rectangular grooves 51 opened on the front and rear sides of the rotating tube 1. The inner cavity of the rectangular grooves 51 is fitted with a plate 52. The front and rear sides of the inner cavity of the adjusting sleeve 3 are provided with rectangular slots 54 that are adapted to the plate 52. The front and rear sides of the adjusting sleeve 3 are provided with second screws 55. The second screws 55 are provided through the front and rear sides of the adjusting sleeve 3. One end of the 5 extends into the inner cavity of the adjusting sleeve 3 and is threaded into the inner cavity of the adjusting screw hole 56. Both sides of the surface of the insert plate 52 are threaded with the first screw 53. One end of the first screw 53 extends through the insert plate 52 and is threaded into the rectangular insert groove 51. By using the second screw 55 and the adjusting screw hole 56 together, the position of the adjusting sleeve 3 can be adjusted, thereby adjusting the length of the steel chain 42. This allows the striking range to be adjusted according to the actual inner diameter of the pipe, so that the steel chain 42 can accurately act on the surface of the concrete residue.

[0022] Working Principle: When using this utility model, the user first engages the end of the steel chain 42 away from the ear plate 41 in the inner cavity of the U-shaped lock head 43. Then, the limiting pin 44 is inserted into the inner cavity of the steel chain 42, and the insert 9 is inserted into the inner cavity of the insertion hole 8. The insert 9 is bent to prevent the limiting pin 44 from slipping out of the inner cavity of the steel chain 42. Next, the insert plate 52 is engaged in the inner cavity of the rectangular groove 51, and then the insert plate 52 is installed and fixed using the first screw 53. Then, the adjusting sleeve 3 is fitted onto the surface of the rotating tube 1, so that the rectangular groove 54 fits onto the surface of the insert plate 52. The position of the adjusting sleeve 3 is adjusted according to the actual usage length to ensure that the extension length of the steel chain 42 meets the required cleaning pipe inner diameter. The left and right sliding of the adjusting sleeve 3 controls the extension length of the steel chain 42. After adjusting to the appropriate length, the user turns the second screw 55 into the inner cavity of the adjusting sleeve 3 and makes it threadedly connected to the adjusting screw hole 56 at the corresponding position. When using it, the user needs to fix and connect the rotating nozzle of the pipe cleaning machine with the rotating hose 10. Then, through the sleeve 7, the user controls the nozzle 2 and the rotating tube 1 to enter the pipe to be cleaned. The user turns on the pipe cleaning machine to supply water and drives the rotating hose 10 to rotate. During the rotation of the rotating hose 10, the rotating tube 1 and the nozzle 2 rotate. At the same time, the cleaning water source is supplied into the inner cavity of the rotating tube 1 and the nozzle 2 and sprayed out from the nozzle 6. During the rotation of the nozzle 2 and the rotating tube 1, the steel chain 42 is thrown out in all directions and hits the concrete residue on the pipe wall, so that the concrete residue attached to the pipe wall can be removed and discharged with the cleaning water source.

[0023] In summary, this concrete conveying pipeline cleaning nozzle device, through the setting of the adjusting component 5, adjusts the position of the adjusting sleeve 3. With the coordinated use of the nozzle 2, rotating pipe 1 and unblocking component 4, it can knock and wash the concrete residue and stubborn residue inside the pipe wall, thereby achieving the purpose of thorough cleaning, speed and effective removal of stubborn residue.
