Description

Technical Field

[0001] This application belongs to the technical field of pipeline cleaning equipment, specifically a concrete conveying pipeline cleaning device. Background Technology

[0002] Concrete conveying pipelines refer to pipelines used to transport concrete to designated locations. Concrete conveying pipelines include straight pipes, bends, tapered pipes, and placing hoses. The requirements for them are low resistance, wear resistance, light weight, easy disassembly and assembly, and good sealing. The commonly used materials are steel pipes and low alloy pipes. The pipe walls must not have defects such as cracks, holes or pits, and the pipe wall thickness is between 2 and 5 mm.

[0003] Existing cleaning devices connect high-pressure spray guns or nozzles to high-pressure pumps. High-pressure water is sprayed out through the spray guns and nozzles. The nozzles limit the water flow area, accelerate the water flow speed, and form the required jet shape, enabling the high-pressure water to concentrate and impact the concrete inside the pipe.

[0004] However, the following problems still exist: the use of high-pressure spray guns and nozzles requires manual control of the rinsing position, and due to different pipe specifications, the nozzles and spray guns cannot be stably set in the center of the pipe. During rinsing, the rinsing pressure is high on the side closer to the pipe and low on the side farther away, which makes it unsuitable for different pipes and causes uneven cleaning. Utility Model Content

[0005] The purpose of this application is to provide a concrete conveying pipeline cleaning device to solve the problems mentioned above, which require manual control of the rinsing position when using high-pressure spray guns and nozzles, and the inability to stably set the nozzles and spray guns in the center of the pipeline due to different pipeline specifications. During rinsing, the rinsing pressure is high on the side closer to the pipeline and low on the side farther away, which cannot be adapted to different pipelines and causes uneven cleaning.

[0006] The technical solution adopted in this application is as follows: A concrete conveying pipeline cleaning device includes a cylinder and a water pump. A receiving shell is fixedly connected to the upper surface of the cylinder. A first moving block is slidably connected to the inner wall of the receiving shell. There are two first moving blocks. A first push plate is rotatably connected to the upper surface of the first moving block on the right side of the receiving shell. A second push plate is rotatably connected to the upper surface of the first moving block on the left side of the receiving shell. The end of the first push plate away from the first moving block passes through the lower surface of the second push plate and extends out of the upper surface of the second push plate. A second moving block is rotatably connected to the side of the second push plate and the side of the first push plate away from the first moving block. A crossbeam is slidably connected to the surface of the second moving block. A roller is rotatably connected to the inner wall of the crossbeam. A bidirectional threaded screw is rotatably connected to the inner wall of the receiving shell. A threaded cylinder is inserted through the side of the first moving block. The inner wall of the threaded cylinder is threadedly connected to the surface of the bidirectional threaded screw.

[0007] Preferably, the number of the storage shells is three, and the three storage shells are arranged in a triangular array on the surface of the cylinder. By setting three storage shells, the rollers can be pressed against the top wall and both sides of the pipe by three crossbars, thus stably supporting the cylinder.

[0008] Preferably, a support block is fixedly connected to the lower surface of the cylinder, a motor is fixedly connected to the upper surface of the support block, a drive rod is fixedly connected to the output end of the motor, a drive gear is fixedly sleeved on the surface of the drive rod, and there are three bidirectional threaded screws, with driven gears fixedly sleeved on the surfaces of the three bidirectional threaded screws. The surfaces of the drive gears mesh with the driven gears. When the motor rotates, it drives the drive rod to rotate, thereby driving the drive gears to rotate. By setting the drive gears, when they are driven by the drive rod, they can simultaneously drive the three driven gears to rotate, thereby driving the three bidirectional threaded screws to rotate, which facilitates the simultaneous adjustment of the second push plate and the first push plate.

[0009] Preferably, a pipe is fixedly connected to the inner wall of the cylinder, a connecting pipe is fixedly connected to the end of the pipe away from the cylinder, a fan-shaped high-pressure nozzle is fixedly connected to the end of the connecting pipe away from the pipe, and an externally threaded connecting pipe is fixedly connected to the surface of the pipe. The connecting pipe is bent toward one side of the pipe, and water flows through the pipe and is sprayed out from the fan-shaped high-pressure nozzle to rinse the inner wall of the pipe.

[0010] Preferably, the outlet end of the water pump is fixedly connected to an outlet hose, and the end of the outlet hose away from the water pump is threadedly connected to a threaded connecting cylinder. The inner wall of the threaded connecting cylinder is threadedly connected to the surface of the external threaded connecting pipe. The inlet end of the water pump is fixedly connected to an outlet pipe, and the end of the outlet pipe away from the water pump is connected to an external water source. The threaded connecting cylinder is aligned with the groove of the external threaded connecting pipe, and then the threaded connecting cylinder is rotated to fix the outlet hose on the external threaded connecting pipe. When the water pump is running, it draws external water into the external threaded connecting pipe through the inlet hose, then flows into the pipe body, and then through the connecting pipe and is sprayed out by a fan-shaped high-pressure nozzle.

[0011] Preferably, a rotating rod is rotatably connected to the front of the second push plate and the first push plate, so that when the lower part of the second push plate and the first push plate is driven, the upper and lower sides of the second push plate and the first push plate rotate stably.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0013] 1. In this application, under normal conditions, the crossbeam is stored inside the cylinder. First, the cylinder is pushed into the pipe. Then, the motor is turned on. The motor drives the drive rod to rotate, which in turn drives the drive gear to rotate. The drive gear then drives the driven gear to rotate, which in turn drives the bidirectional threaded screw to rotate. The bidirectional threaded screw then uses the threaded cylinder to move the first moving block. At this time, the upper and lower sides of the first and second push plates approach each other and push the crossbeam to move until the roller is driven to fit against the inner wall of the pipe. Then, the motor is stopped. After that, the threaded connecting cylinder is rotated to fix the water outlet hose to the external threaded connecting pipe. Then, the water pump is turned on. The water pump runs and draws external water into the external threaded connecting pipe through the water inlet hose. Then, the water flows into the pipe and is sprayed out through the connecting pipe and the fan-shaped high-pressure nozzle to rinse the inner wall of the pipe. Thus, the device can adapt to pipes of different specifications. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Example:

[0021] Reference Figure 2-4A concrete conveying pipeline cleaning device includes a cylinder 1 and a water pump 20. A receiving shell 2 is fixedly connected to the upper surface of the cylinder 1. Two first moving blocks 3 are slidably connected to the inner wall of the receiving shell 2. A first push plate 6 is rotatably connected to the upper surface of the first moving block 3 on the right side of the receiving shell 2, and a second push plate 23 is rotatably connected to the upper surface of the first moving block 3 on the left side of the receiving shell 2. The end of the first push plate 6 away from the first moving block 3 passes through the lower surface of the second push plate 23 and extends out of the upper surface of the second push plate 23. The second push plate 23 and the first push plate 6 are rotatably connected to the side away from the first moving block 3 by a second moving block 7. The surface of the second moving block 7 is slidably connected to a cross frame 8. The inner wall of the cross frame 8 is rotatably connected to a roller 9. By setting the first moving block 3 and the second moving block 7, when the first driving block 3 is driven, the second push plate 23 and the first push plate 6 rotate, and the included angle between them becomes smaller. At the same time, the included angle above the first push plate 6 and the second push plate 23 becomes smaller. The first push plate 6 and the second push plate 23 move above the second moving block 7 and push the cross frame 8.

[0022] Reference Figure 2-3 The inner wall of the housing 2 is rotatably connected to a bidirectional threaded screw 5. A threaded cylinder 10 is inserted through the side of the first moving block 3. The inner wall of the threaded cylinder 10 is threadedly connected to the surface of the bidirectional threaded screw 5. The cylinder 1 is pushed into the pipe. Then the motor 13 is turned on. The motor 13 drives the drive rod 14 to rotate. The drive rod 14 rotates and drives the drive gear 16 to rotate. The drive gear 16 rotates and drives the driven gear 11 to rotate. The driven gear 11 rotates and drives the bidirectional threaded screw 5 to rotate. The bidirectional threaded screw 5 rotates and then uses the threaded cylinder 10 to drive the first moving block 3 to move. At this time, the upper and lower sides of the first push plate 6 and the second push plate 23 approach each other and push the cross frame 8 to move until the roller 9 is driven to fit against the inner wall of the pipe.

[0023] Reference Figure 1-2 There are three storage shells 2, and the three storage shells 2 are arranged in a triangular array on the surface of the cylinder 1. By setting three storage shells 2, the rollers 9 can be pressed against the top wall and both sides of the pipe by three crossbars 8 respectively, so as to stably support the cylinder 1.

[0024] Reference Figure 2-3A support block 12 is fixedly connected to the lower surface of the cylinder 1, and a motor 13 is fixedly connected to the upper surface of the support block 12. A drive rod 14 is fixedly connected to the output end of the motor 13. A drive gear 16 is fixedly sleeved on the surface of the drive rod 14. There are three bidirectional threaded screws 5, and driven gears 11 are fixedly sleeved on the surfaces of the three bidirectional threaded screws 5. The surfaces of the drive gears 16 mesh with the driven gears 11. When the motor 13 rotates, it drives the drive rod 14 to rotate, thereby driving the drive gears 16 to rotate. By setting the drive gears 16, when they are driven by the drive rod 14, they can simultaneously drive the three driven gears 11 to rotate, thereby driving the three bidirectional threaded screws 5 to rotate, which facilitates the simultaneous adjustment of the second push plate 23 and the first push plate 6.

[0025] Reference Figure 1-2 A pipe body 17 is fixedly connected to the inner wall of the cylinder 1. A connecting pipe 18 is fixedly connected to the end of the pipe body 17 away from the cylinder 1. A fan-shaped high-pressure nozzle 19 is fixedly connected to the end of the connecting pipe 18 away from the pipe body 17. An externally threaded connecting pipe 24 is fixedly connected to the surface of the pipe body 17. The connecting pipe 18 is bent toward one side of the pipe. Water flows through the pipe body 17 and is sprayed out from the fan-shaped high-pressure nozzle 19 to rinse the inner wall of the pipe.

[0026] Reference Figure 2-3 The outlet end of the water pump 20 is fixedly connected to an outlet hose 22. The end of the outlet hose 22 away from the water pump 20 is threadedly connected to a threaded connecting sleeve 15. The inner wall of the threaded connecting sleeve 15 is threadedly connected to the surface of the external threaded connecting pipe 24. The inlet end of the water pump 20 is fixedly connected to an outlet pipe 21. The end of the outlet pipe 21 away from the water pump 20 is connected to an external water source. The threaded connecting sleeve 15 includes a sealing ring, which is an existing structure. When threadedly connected to the external threaded connecting pipe 24, it seals the gap between the threaded connecting sleeve 15 and the external threaded connecting pipe 24, reducing the occurrence of water leakage when passing through the external threaded connecting pipe 24. The threaded connecting sleeve 15 is aligned with the groove of the external threaded connecting pipe 24. Then, the threaded connecting sleeve 15 is rotated to fix the outlet hose 22 to the external threaded connecting pipe 24. The water pump 20 operates to draw external water into the external threaded connecting pipe 24 through the inlet hose 21, then flows into the pipe body 17, and then through the connecting pipe 18 and is sprayed out by the fan-shaped high-pressure nozzle 19.

[0027] Reference Figure 1-2 The front of the second push plate 23 and the first push plate 6 are rotatably connected to a rotating rod 4. When the lower part of the second push plate 23 and the first push plate 6 is driven, the upper and lower sides of the second push plate 23 and the first push plate 6 rotate stably.

[0028] The implementation principle of a concrete conveying pipeline cleaning device according to this application is as follows: Under normal conditions, the horizontal frame 8 is stored in the housing 2. First, the cylinder 1 is pushed into the pipeline. Then, the motor 13 is turned on. The motor 13 drives the drive rod 14 to rotate. The rotation of the drive rod 14 drives the drive gear 16 to rotate. The rotation of the drive gear 16 then drives the driven gear 11 to rotate. The rotation of the driven gear 11 then drives the bidirectional threaded screw 5 to rotate. The rotation of the bidirectional threaded screw 5 then uses the threaded cylinder 10 to drive the first moving block 3 to move. At this time, the first push plate 6 and the second push plate 6 move simultaneously. The upper and lower sides of plate 23 move closer to each other and push the crossbar 8 to move until the roller 9 is driven to fit against the inner wall of the pipe. Then, the motor 13 is stopped. Then, the threaded connecting cylinder 15 is rotated to fix the water outlet hose 22 to the external threaded connecting pipe 24. Then, the water pump 20 is turned on. The water pump 20 runs and draws external water into the external threaded connecting pipe 24 through the water inlet hose 21. Then, the water flows into the pipe body 17 and is sprayed out through the connecting pipe 18 and the fan-shaped high-pressure nozzle 19 to rinse the inner wall of the pipe. This makes the equipment adaptable to pipes of different specifications.
