Description

Technical Field

[0001] The utility model relates to the technical field of grooving devices for water supply pipeline construction, and more specifically, it relates to a grooving device for water supply pipeline construction. Background Art

[0002] In the existing technology, there are some problems in the design of grooving devices for water supply pipeline construction, which have an adverse impact on the construction process and the environment.

[0003] First of all, most grooving devices are usually handheld structures. This design requires construction workers to hold the device for a long time during operation, increasing labor intensity and fatigue. At the same time, the handheld structure may cause the device to be unstable, affecting the accuracy and efficiency of construction. During the grooving process, due to the vibration and friction of the device, a large amount of dust will be generated. These dusts not only pose a threat to the health of construction workers, but also reduce the visibility of the construction site, affecting construction safety.

[0004] Secondly, to solve the above problems, some devices use the method of spraying water flow to achieve the purpose of dust reduction. However, in the existing technology, the pipeline structure is usually relatively simple and cannot flexibly control the water flow rate. This means that during the construction process, the spraying intensity of water cannot be adjusted according to actual needs, resulting in poor dust reduction effect. In addition, due to the inability to accurately control the water flow rate, it may cause waste of water resources and increase construction costs.

[0005] In addition, in the existing technology, some devices use some mechanisms to adjust the water flow rate, but their structures are relatively simple and cannot ensure the stability of the water flow after adjustment. This means that during the construction process, the water flow rate may change due to device vibration or other external factors. This instability will affect the dust reduction effect and may even lead to safety accidents during the construction process. At the same time, due to the simple structure, these devices are prone to looseness during long-term use and need to be adjusted and maintained frequently, increasing the complexity and cost of construction.

[0035] A spray head 28 is arranged above the cutting tool 24. One end of the spray head 28 is connected to the fixed pipe 2. One end of the adjusting sleeve 9 is provided with a connecting pipe 29. The adjusting sleeve 9 and the connecting pipe 29 are movably connected. The other end of the connecting pipe 29 is provided with a corrugated pipe 30.

[0038] Sliding rails 35 are symmetrically arranged on both sides of the base 1, and sliding grooves 36 are provided at corresponding positions on the mounting seat 27. The sliding rails 35 are adapted to the sliding grooves 36.

[0039] In this embodiment, when the device needs to be used, the conveying speed of the water flow can be adjusted according to requirements and the wall material. First, rotate the mating sleeve 10. The mating sleeve 10 will drive the arc groove and the through groove 16 to move. At the same time, the mating sleeve 10 will drive the return block 17 to move. Then the return block 17 will cooperate with the connecting block 13 to squeeze the spring 14. When the spring 14 is squeezed to the limit, the position of the through groove 16 just corresponds to the position of the limiting plate 19. Then push the sliding sleeve 11. The sliding sleeve 11 will slide along the limiting plate 19 and the limiting groove 20. And the sliding sleeve 11 will cooperate with the mating sleeve 10 to squeeze the push spring 21. At the same time, the sliding sleeve 11 will drive the mating rod 12 and the mating plate 18 to pass through the through groove 16. When the push spring 21 is squeezed to the limit, the corresponding mating plate 18 just moves to one side of the mating sleeve 10. Then release the mating sleeve 10. The spring 14 pushes the return block 17 and the mating sleeve 10 to reset, so that the mating rod 12 enters the arc groove, and the sliding sleeve 11 is clamped on one side of the mating sleeve 10 through the mating rod 12 and the corresponding mating plate 18. At this time, the outside of the adjusting sleeve 9 loses the limit of the sliding sleeve 11. Then rotate the adjusting sleeve 9. The adjusting sleeve 9 drives the prism rod 5 to rotate through the connecting frame 8 arranged inside. Then the prism rod 5 drives the movable frame 3 to rotate through the prism sleeve 4. Since the movable frame 3 is movably connected to the inner wall of the fixed pipe 2 through a thread, then the movable frame 3 will slide spirally along the inner wall of the fixed pipe 2. Then the distance between the movable frame 3 and the rotating frame 7 will change. Then the gap between the elastic plates 6 will change, thereby changing the passing speed of the water flow. After adjustment, release the adjusting sleeve 9. Then rotate the mating sleeve 10. The mating sleeve 10 drives the return block 17 to squeeze the spring 14 again. Then when the positions of the through groove 16 and the mating plate 18 correspond, the push spring 21 pushes the sliding sleeve 11 to reset, so that the sliding sleeve 11 resets along the sliding rails 35 and the sliding grooves 36. At the same time, the sliding sleeve 11 will drive the mating rod 12 and the mating plate 18 to reset. Then the sliding sleeve 11 will be sleeved outside the adjusting sleeve 9 to form a limit on the adjusting sleeve 9 to prevent the adjusting sleeve 9 from rotating. Then release the mating sleeve 10. The spring 14 pushes the return block 17 and drives the mating sleeve 10 to reset, so that the positions of the through groove 16 and the mating plate 18 no longer correspond, so that the mating rod 12 forms a limit on the sliding sleeve 11 to prevent the sliding sleeve 11 from moving, thus ensuring the stability after the flow rate adjustment.

[0040] Please refer to Figure 1 and Figure 3, as an embodiment of the grooving device: The grooving device includes a movable seat 22, a driving assembly 23, a cutting tool 24, a cylinder 25, a piston rod 26, and a mounting seat 27. The movable seat 22 is movably arranged on the mounting seat 27. The driving assembly 23 is installed on the movable seat 22. The cutting tool 24 is movably installed on one side of the movable seat 22. The cylinder 25 is installed on the mounting seat 27. One end of the piston rod 26 is connected to the output end of the cylinder 25, and the other end of the piston rod 26 is connected to the movable seat 22. The mounting seat 27 is movably installed inside the base 1.

[0041] Above the cutting tool 24, there is a spray head 28. One end of the spray head 28 is connected to the fixed pipe 2. One end of the adjusting sleeve 9 is provided with a connecting pipe 29. The adjusting sleeve 9 and the connecting pipe 29 are movably connected. The other end of the connecting pipe 29 is provided with a corrugated pipe 30. The other end of the corrugated pipe 30 is connected to an external device through another connecting pipe 29.

[0042] Inside the mounting seat 27, there is a guide rail 31. Below the movable seat 22, a guide groove 32 is opened. The guide groove 32 is adapted to the guide rail 31.

[0043] Inside the base 1, there is a hydraulic cylinder 33. The output end of the hydraulic cylinder 33 is connected with a hydraulic rod 34. The top end of the hydraulic rod 34 is connected to the bottom end of the mounting seat 27.

[0044] On both sides of the base 1, slide rails 35 are symmetrically arranged. At the corresponding positions of the mounting seat 27, sliding grooves 36 are opened. The slide rails 35 are adapted to the sliding grooves 36.

[0045] More specifically, when the device needs to be used, first, turn on the hydraulic cylinder 33. The hydraulic cylinder 33 drives the mounting seat 27 to slide along the slide rails 35 and the sliding grooves 36 through the hydraulic rod 34 connected to the output end. After adjusting the initial height of the device, turn off the hydraulic cylinder 33. Then, turn on the driving assembly 23 to make the driving assembly 23 drive the cutting tool 24 to rotate. Then, turn on the cylinder 25. The cylinder 25 pushes the movable seat 22 to slide along the guide rail 31 and the guide groove 32 through the piston rod 26 connected to the output end. At the same time, turn on the external conveying device to deliver water to the spray head 28 through the connecting pipe 29 and the corrugated pipe 30, and spray it out from below and the front end of the spray head 28 to achieve the function of dust reduction. At the same time, the hydraulic cylinder 33 can be turned on to make the hydraulic cylinder 33 drive the mounting seat 27 to slowly move along the slide rails 35 and the sliding grooves 36 through the hydraulic rod 34 connected to the output end, so as to complete the grooving work. Then, after the grooving is completed, use a grooving tool to groove.

[0046] In summary, when the overall device is in use or operation: when the device needs to be used, the conveying speed of the water flow can be adjusted according to the requirements and the wall material. First, rotate the mating sleeve 10. The mating sleeve 10 will drive the arc-shaped groove and the through groove 16 to move. At the same time, the mating sleeve 10 will drive the return block 17 to move. Then, the return block 17 will cooperate with the connecting block 13 to squeeze the spring 14. When the spring 14 is squeezed to the limit, the position of the through groove 16 just corresponds to the position of the limiting plate 19. Then, push the sliding sleeve 11. The sliding sleeve 11 will slide along the limiting plate 19 and the limiting groove 20. And the sliding sleeve 11 will cooperate with the mating sleeve 10 to squeeze the push spring 21. At the same time, the sliding sleeve 11 will drive the mating rod 12 and the mating plate 18 to pass through the through groove 16. When the push spring 21 is squeezed to the limit, the corresponding mating plate 18 just moves to one side of the mating sleeve 10. Then, release the mating sleeve 10. The spring 14 pushes the return block 17 and the mating sleeve 10 to reset, so that the mating rod 12 enters the arc-shaped groove, and the sliding sleeve 11 is clamped on one side of the mating sleeve 10 through the mating rod 12 and the corresponding mating plate 18. At this time, the outside of the adjusting sleeve 9 loses the limit of the sliding sleeve 11. Then, rotate the adjusting sleeve 9. The adjusting sleeve 9 drives the prism rod 5 to rotate through the connecting frame 8 arranged inside. Then, the prism rod 5 drives the movable frame 3 to rotate through the prism sleeve 4. Since the movable frame 3 is movably connected to the inner wall of the fixed tube 2 through a thread, then the movable frame 3 will slide spirally along the inner wall of the fixed tube 2. Then, the distance between the movable frame 3 and the rotating frame 7 will change. Then, the gap between the elastic plates 6 will change, thereby changing the passing speed of the water flow. After adjustment to the appropriate value, release the adjusting sleeve 9. Then, rotate the mating sleeve 10. The mating sleeve 10 drives the return block 17 to squeeze the spring 14 again. Then, when the positions of the through groove 16 and the mating plate 18 correspond, the push spring 21 pushes the sliding sleeve 11 to reset, so that the sliding sleeve 11 resets along the slide rail 35 and the chute 36. At the same time, the sliding sleeve 11 will drive the mating rod 12 and the mating plate 18 to reset. Then, the sliding sleeve 11 will be sleeved on the outside of the adjusting sleeve 9 to form a limit for the adjusting sleeve 9 to prevent the adjusting sleeve 9 from rotating. Then, release the mating sleeve 10. The spring 14 pushes the return block 17 and drives the mating sleeve 10 to reset, so that the positions of the through groove 16 and the mating plate 18 no longer correspond, so that the mating rod 12 forms a limit for the sliding sleeve 11 to prevent the sliding sleeve 11 from moving, thus ensuring the stability after the flow rate adjustment.

[0047] When the equipment needs to be used, first open the hydraulic cylinder 33. The hydraulic cylinder 33 drives the mounting seat 27 to slide along the slide rail 35 and the slide groove 36 through the hydraulic rod 34 connected to the output end. After adjusting the initial height of the equipment, close the hydraulic cylinder 33, and then open the drive assembly 23, so that the drive assembly 23 drives the cutting knife 24 to select, and then open the cylinder 25. The cylinder 25 pushes the movable seat 22 to slide along the guide rail 31 and the guide groove 32 through the piston rod 26 connected to the output end. At the same time, open the external conveying equipment, and escort the water to the nozzle 28 through the connecting pipe 29 and the bellows 30, and spray it from the bottom and front end of the nozzle 28 to achieve the function of dust reduction. At the same time, the hydraulic cylinder 33 can be opened, so that the hydraulic cylinder 33 drives the mounting seat 27 to move slowly along the slide rail 35 and the slide groove 36 through the hydraulic rod 34 connected to the output end, thereby completing the grooving work. Then, after the grooving is completed, the grooving can be performed with the help of a grooving tool.

[0048] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded.
