Description
Technical Field
[0001] This invention relates to the technical field of auxiliary equipment for pipeline laying, and in particular to a device for laying building water supply and drainage pipelines. Background Technology
[0002] Drainage pipes are primarily responsible for draining rainwater, sewage, and agricultural irrigation water. They are classified as plastic, concrete, and reinforced concrete pipes. Laying drainage pipes involves burying them underground. Currently, laying drainage pipes requires first creating a trench in the ground, then placing the pipes in the trench, and finally covering them with soil.
[0003] Because the soil in different terrains and landforms contains impurities of varying sizes that are difficult to break, it is difficult to ensure that the depth and width of the trenches are uniform, thus affecting the accuracy of the drainage pipe laying. Summary of the Invention
[0004] This application provides a building water supply and drainage pipe laying device that can effectively ensure the consistency of the groove depth and width of the laying trench.
[0005] This application provides a building water supply and drainage pipeline laying device, which adopts the following technical solution: A building water supply and drainage pipe laying device is used to pre-open laying trenches on the ground for laying drainage pipes. The device includes a frame, a reinforced frame chassis at the bottom of the frame, a swing arm rotatably mounted on the bottom of the reinforced frame chassis, a hydraulic rod for driving the swing arm at the bottom of the reinforced frame chassis, a drive motor mounted on the swing arm, a drive shaft connected to the output end of the drive motor, an installation shaft mounted on the drive shaft, a plurality of U-shaped retaining strips arranged on the radial surface of the installation shaft, the plurality of U-shaped retaining strips being distributed at equal angles around the central axis of the installation shaft, a first drive motor being installed inside the U-shaped retaining strips, a soil-cutting shaft connected to the output end of the first drive motor, and a plurality of cutter heads on the surface of the soil-cutting shaft.
[0006] By adopting the above technical solution, the swing arm is adjusted to a suitable angle via a hydraulic rod. At this time, the digging shaft on the swing arm contacts the ground surface, and the drive motor is started, causing the mounting shaft to rotate. Since the digging shaft is set at an equal angle on the mounting shaft, the rotation of the mounting shaft can effectively break up impurities of different sizes and form a paving groove on the ground surface. This effectively ensures the consistency of the paving groove's depth and width, thereby guaranteeing the quality and stability of the drainage pipe. Furthermore, the digging shaft can rotate on the mounting shaft via the first drive motor, adapting to different terrains and landforms, thus making it more widely applicable.
[0007] Preferably, the frame has an internal mounting cavity, the mounting cavity has an impeller, the impeller is rotatably mounted on the chassis of the reinforcement frame machine, a second drive motor is located at the center of the impeller, the chassis of the reinforcement frame machine has a dust collection box, the input end of the dust collection box is connected to the mounting cavity inside the frame, the frame has a dust inlet, and the dust inlet is connected to the mounting cavity.
[0008] By adopting the above technical solution, by starting the second drive motor, the impeller rotates inside the placement chamber and forms a negative pressure, which can absorb the dust generated during the grooving process through the dust inlet and store it inside the dust collection box. By vacuuming, the impact of the dust generated during the grooving process on the construction personnel can be reduced, thereby protecting the health of the construction personnel.
[0009] Preferably, the dust inlet is located on the side of the frame, and the frame is provided with a dust baffle plate located above the dust inlet.
[0010] By adopting the above technical solution, since the dust inlet is located on the side of the frame, it can effectively prevent soil from below the frame from entering the dust inlet and effectively prevent soil from clogging the dust inlet. The dust baffle is located above the dust inlet and can effectively block the dust generated during the grooving process from splashing upwards, reducing the impact of dust on construction personnel.
[0011] Preferably, the lower surface of the dust baffle is provided with an arc-shaped guide surface, which is located near the upper side of the dust inlet.
[0012] By adopting the above technical solution, the arc-shaped guide surface can guide the dust generated during the grooving process to the dust inlet, making it easier to be sucked into the dust collection box. The arc-shaped guide surface can also prevent dust from splashing downwards, reducing the impact of dust on construction workers. In addition, the arc-shaped guide surface can guide the dust to the dust inlet more concentratedly, improving the dust collection effect. In summary, by setting an arc-shaped guide surface on the lower surface of the dust baffle plate and placing it near the upper side of the dust inlet, the dust can be guided to the dust inlet, preventing dust from splashing, improving the dust collection effect, and facilitating subsequent cleaning work.
[0013] Preferably, a guide plate is provided at the head position of the reinforced frame chassis, the end of the guide plate is tapered, and the guide plate is a downward streamlined structure.
[0014] By adopting the above technical solution, the conical structure of the guide plate can guide the broken soil generated during trenching to the sides of the reinforced machine chassis, thereby assisting in trenching. By designing the guide plate as a downward streamlined structure, the splashing and scattering of broken soil can be reduced, improving the efficiency of the operation. The broken soil can pass through the guide plate more smoothly, reducing the accumulation and compression of broken soil, thereby improving work efficiency.
[0015] Preferably, the guide plate has connecting rods on both sides, one end of the connecting rod is connected to the guide plate, and the other end of the connecting rod is provided with a fork plate, which has a plurality of fork teeth.
[0016] By adopting the above technical solution, the fork teeth on the fork plate are used to remove large particles of gravel from the soil in the laying trench. Large particles of gravel may cause instability in the pipeline. By removing large particles of gravel, the risk of pipeline misalignment and movement can be reduced, and the stability of the pipeline can be increased.
[0017] Preferably, a fixing rod is provided at the rear of the reinforced frame chassis, a rotating shaft is provided at the bottom of the fixing rod, a shaping wheel is provided on the rotating shaft, and the edge of the shaping wheel is chamfered.
[0018] By adopting the above technical solution, after the laying trench is formed on the ground, the shaping wheels at the bottom of the reinforcing machine chassis move and compress inside the laying trench as the chassis moves, effectively solidifying the soil on the inner wall of the laying trench and making the soil inside the laying trench more firm. By solidifying the soil on the inner wall of the laying trench, the stability of the pipeline can be increased. The solidified soil provides more stable support for the pipeline, reducing the possibility of pipeline movement and displacement.
[0019] Preferably, the fixing rod is rotatably connected to the chassis of the reinforcement frame machine, and a cylinder is provided at the bottom of the chassis of the reinforcement frame machine, with the output end of the cylinder hinged to the middle of the fixing rod.
[0020] By adopting the above technical solution, the cylinder causes the fixed rod to rotate with the chassis of the reinforcement frame, which is used to adjust the angle of the shaping wheel on the fixed rod. By adjusting the angle of the shaping wheel, the squeezing force and compaction effect on the soil can be changed, thereby realizing the adjustment of construction parameters.
[0021] Preferably, a cleaning assembly for cleaning debris from the surface of the shaping wheel and the planing shaft is provided between the fixed rod and the swing arm.
[0022] By adopting the above technical solution, the debris on the surface of the shaping wheel and the cutting shaft may affect their normal operation. The cleaning component can remove the debris in time, keep the shaping wheel and the cutting shaft clean, and thus improve work efficiency. The cleaning component can quickly and easily remove debris and reduce downtime.
[0023] Preferably, the cleaning assembly includes a cleaning frame, the interior of which is provided with a cleaning groove for accommodating a shaping wheel and a soil-scraping shaft, and the cleaning groove of the cleaning frame is provided with cleaning bristles.
[0024] By adopting the above technical solution, the rotation of the fixed rod and the swing arm respectively positions the shaping wheel and the soil-scraping shaft inside the cleaning groove. By activating the shaping wheel and the soil-scraping shaft, relative motion is generated between them and the cleaning brush bristles, which is used to clean the surface of the shaping wheel and the soil-scraping shaft. During the construction process, the shaping wheel and the soil-scraping shaft will accumulate mud, debris, etc. The combined action of the cleaning groove and the cleaning brush bristles can thoroughly clean the surface of the shaping wheel and the soil-scraping shaft, ensuring that the work is not interfered with by debris and improving the construction quality.
[0025] In summary, this application has the following beneficial effects: 1. Adjust the swing arm to a suitable angle using the hydraulic rod. At this point, the digging shaft on the swing arm contacts the ground surface, and the drive motor is started, causing the mounting shaft to rotate. Since the digging shaft is set at an equal angle on the mounting shaft, the rotation of the mounting shaft can effectively break up impurities of different sizes and form a paving groove on the ground surface. This effectively ensures the consistency of the paving groove's depth and width, thereby guaranteeing the quality and stability of the drainage pipe. Furthermore, the digging shaft can rotate on the mounting shaft via the first drive motor, adapting to different terrains and landforms, thus making it more widely applicable.

[0027] This invention discloses a building water supply and drainage pipe laying device, such as... Figure 1 , Figure 2 and Figure 3 As shown, a laying device for laying drainage pipes is used to pre-open laying trenches on the ground. This device includes a frame 1, a reinforcing chassis 2 at the bottom of the frame 1, a swing arm 3 rotatably mounted on the bottom of the reinforcing chassis 2, and a hydraulic rod for driving the swing arm 3 at the bottom of the chassis 2. A drive motor is mounted on the swing arm 3, and the output end of the drive motor is connected to a drive shaft 4. An installation shaft 5 is mounted on the drive shaft 4, and several U-shaped retaining strips 6 are arranged on the radial surface of the installation shaft 5. It is worth noting that the angle between the U-shaped retaining strips 6 and the central axis of the installation shaft 5 is 15°. This 15° angle reduces stress concentration between the U-shaped retaining strips 6 and the installation shaft 5; by dispersing stress, the stress level of the U-shaped retaining strips 6 can be reduced, thereby extending their service life. To improve lifespan and durability, several U-shaped clips 6 are distributed at equal angles around the central axis of the mounting shaft 5. A first drive motor 7 is installed inside each U-shaped clip 6, and the output end of the first drive motor 7 is connected to a digging shaft 8. The surface of the digging shaft 8 is equipped with several cutter heads 9. Through a hydraulic rod, the swing arm 3 is adjusted to a suitable angle. At this time, the digging shaft 8 on the swing arm 3 contacts the ground surface, and the drive motor is activated, causing the mounting shaft 5 to rotate. Because the digging shaft 8 is set at equal angles on the mounting shaft 5, it is used to form a paving groove on the ground surface, ensuring that the groove depth and width are uniform, thereby guaranteeing the quality and stability of the drainage pipe. Furthermore, the digging shaft 8 can rotate on the mounting shaft 5 via the first drive motor 7, adapting to different terrains and landforms, thus having wider applicability.
[0028] like Figure 4 and Figure 5As shown, the frame 1 has a mounting cavity 10 inside, and an impeller 11 is installed inside the mounting cavity 10. The impeller 11 is rotatably mounted on the chassis 2 of the reinforcement frame machine. A second drive motor is located at the center of the impeller 11. A dust collection box 12 is installed on the chassis 2 of the reinforcement frame machine. The input end of the dust collection box 12 is connected to the mounting cavity 10 inside the frame 1. The frame 1 has a dust inlet 13, which is connected to the mounting cavity 10. By starting the second drive motor, the impeller 11 rotates inside the mounting cavity 10 and forms a negative pressure, which can absorb the dust generated during the grooving process through the dust inlet 13 and store it inside the dust collection box 12. By vacuuming the dust, the impact of the dust generated during the grooving process on the construction personnel can be reduced, thereby protecting the construction personnel. Personnel health; since no large amount of dust is generated during the grooving process, construction personnel do not need to frequently stop to clean up dust, thereby improving construction efficiency; Environmental hygiene protection: vacuuming can effectively reduce the impact of dust generated during grooving on environmental hygiene, reduce dust flying, and keep the surrounding environment clean; storing the generated dust in the dust collection box 12 by vacuuming can reduce cleaning costs and frequency, and improve construction efficiency; In summary, by using the second drive motor to rotate the impeller 11 inside the mounting cavity 10 and create negative pressure, the impact of dust generated during grooving on construction personnel and the environment can be reduced, improving construction efficiency and safety; the dust inlet 13 is located on the side of the frame 1, and the frame A dust baffle 14 is provided on the frame 1, positioned above the dust inlet 13. Since the dust inlet 13 is located on the side of the frame 1, it effectively prevents soil from below the frame 1 from entering the dust inlet 13, thus preventing soil blockage. The dust baffle 14, positioned above the dust inlet 13, effectively blocks dust generated during the grooving process from splashing upwards, reducing the impact of dust on construction personnel. Therefore, the dust baffle 14 guides and concentrates dust, improving the dust collection effect. Furthermore, the dust baffle 14 allows dust to be stored more concentratedly in the dust collection equipment, facilitating subsequent maintenance and cleaning. In summary, placing the dust baffle 14 above the dust inlet 13 prevents dust splashing and improves dust collection efficiency. The dust baffle 14 has an arc-shaped guide surface on its lower surface, which is close to the upper side of the dust inlet 13. The arc-shaped guide surface can guide the dust generated during the grooving process to the dust inlet 13, making it easier to be sucked into the dust collection box 12. The arc-shaped guide surface can also prevent dust from splashing downwards, reducing the impact of dust on construction personnel. In addition, the arc-shaped guide surface can guide the dust to the dust inlet 13 more concentratedly, improving the dust collection effect. In summary, by setting the lower surface of the dust baffle 14 to have an arc-shaped guide surface and placing it close to the upper side of the dust inlet 13, the dust can be guided to the dust inlet 13, preventing dust from splashing, improving the dust collection effect, and facilitating subsequent cleaning work.
[0029] like Figure 6 and Figure 7As shown, a guide plate 15 is provided at the head of the reinforced frame chassis 2. The end of the guide plate 15 is conical, and the guide plate 15 has a downward streamlined structure. The conical structure of the guide plate 15 can guide the broken soil generated during trenching to the sides of the reinforced frame chassis 2, thereby assisting in trenching. By designing the guide plate 15 with a downward streamlined structure, the splashing and scattering of broken soil can be reduced, improving the efficiency of the operation. The broken soil can pass through the guide plate 15 more smoothly, reducing the accumulation and compression of broken soil, thereby improving work efficiency. Connecting rods 16 are provided on both sides of the guide plate 15, and one end of the connecting rod 16 is connected to the guide plate. 15. The other end of the connecting rod 16 is provided with a fork plate 17, and the fork plate 17 is provided with several fork teeth 18. By using the fork teeth 18 on the fork plate 17, large particles of gravel in the paving trench soil can be removed. Large particles of gravel may cause instability in the pipeline. By removing large particles of gravel, the risk of pipeline misalignment and movement can be reduced, and the stability of the pipeline can be increased. Moreover, large particles of gravel may cause pressure and friction on the pipeline. By removing large particles of gravel, the risk of damage to the pipeline can be reduced, and the service life of the pipeline can be extended. In addition, large particles of gravel may cause pipeline rupture or leakage. By removing large particles of gravel, the safety of the pipeline can be ensured and the occurrence of accidents can be reduced.
[0030] like Figure 6 and Figure 8As shown, a fixing rod 19 is provided at the rear of the reinforced frame chassis 2, and a rotating shaft 20 is provided at the bottom of the fixing rod 19. A shaping wheel 21 is provided on the rotating shaft 20, and the edge of the shaping wheel 21 is chamfered. After a paving groove is formed on the surface, as the reinforced frame chassis 2 moves, the shaping wheel 21 at the bottom of the reinforced frame chassis 2 moves and compresses inside the paving groove, which can effectively solidify the soil on the inner wall of the paving groove, making the soil inside the paving groove more firm. By solidifying the soil on the inner wall of the paving groove, the stability of the pipeline can be increased. The compacted soil provides more stable support for the pipeline, reducing the possibility of pipeline movement and displacement. The fixed rod 19 is rotatably connected to the reinforcing frame chassis 2, and a cylinder 22 is located at the bottom of the chassis 2. The output end of the cylinder 22 is hinged to the middle of the fixed rod 19. The cylinder 22 causes the fixed rod 19 to rotate relative to the chassis 2, adjusting the angle of the shaping wheel 21 on the fixed rod 19. By adjusting the angle of the shaping wheel 21, the compressive force and compaction effect on the soil can be changed, thereby achieving… Adjusting construction parameters is crucial; different soil conditions and pipeline requirements may necessitate different compaction effects, which can be achieved by adjusting the angle to meet diverse construction needs. A suitable angle reduces resistance and friction, improving the wheel's mobility in the soil and accelerating construction. Furthermore, adjusting the angle of the shaping wheel 21 allows for more uniform and thorough soil compaction, enhancing construction quality. A suitable angle ensures sufficient soil solidification during compaction, reducing loosening and deformation of the soil around the pipeline. Adjusting the angle of the shaping wheel 21 minimizes soil damage and disturbance, reducing the environmental impact of construction. A suitable angle maximizes the preservation of soil structure and stability, minimizing soil erosion and loss. In summary, by rotating the fixed rod 19 and the reinforcing frame chassis 2 using the cylinder 22, the angle of the shaping wheel 21 on the fixed rod 19 can be adjusted, enabling the modification of construction parameters, improving construction efficiency and quality, and reducing environmental impact. This is highly beneficial for pipeline laying during construction.
[0031] like Figure 6As shown, a cleaning assembly 23 for cleaning debris from the surfaces of the shaping wheel 21 and the cutting shaft 8 is provided between the fixed rod 19 and the swing arm 3. Debris on the surfaces of the shaping wheel 21 and the cutting shaft 8 may affect their normal operation. The cleaning assembly 23 can remove the debris in a timely manner, keeping the shaping wheel 21 and the cutting shaft 8 clean, thereby improving work efficiency. The cleaning assembly 23 can quickly and easily remove debris, reducing downtime. Furthermore, the accumulation of debris may cause equipment jamming or seizure. Timely removal of debris by the cleaning assembly 23 can reduce the risk of equipment failure and ensure the continuity and stability of construction. Additionally, debris on the surfaces of the shaping wheel 21 and the cutting shaft 8 may affect the equipment's operation. The cleaning component 23 removes debris, improving equipment stability and operational safety, and reducing the occurrence of accidents. In summary, by providing a cleaning component 23 between the fixed rod 19 and the swing arm 3 for cleaning debris from the surfaces of the shaping wheel 21 and the cutting shaft 8, work efficiency can be improved, equipment lifespan extended, failure risk reduced, and safety enhanced. This is highly beneficial for pipeline laying during construction. The cleaning component 23 includes a cleaning frame 2301, with a cleaning groove 2302 inside the frame 2301 to accommodate the shaping wheel 21 and the cutting shaft 8. Cleaning bristles 23 are located within the cleaning groove 2302 of the frame 2301. 03; By rotating the fixed rod 19 and the swing arm 3, the shaping wheel 21 and the shoveling shaft 8 are respectively positioned inside the cleaning groove 2302. Activating the shaping wheel 21 and the shoveling shaft 8 creates relative movement between them and the cleaning brush 2303, cleaning their surfaces. During construction, the shaping wheel 21 and the shoveling shaft 8 accumulate dirt and debris. The combined action of the cleaning groove 2302 and the cleaning brush 2303 thoroughly cleans their surfaces, ensuring they are not disturbed by debris and improving construction quality. The dirt and debris on the surface of the shaping wheel 21 and the shoveling shaft 8 may... This can lead to wear and corrosion. Regular cleaning can reduce these damages, extend the service life of the shaping wheel 21 and the cutting shaft 8, and reduce maintenance and replacement costs. Moreover, the cleanliness of the surfaces of the shaping wheel 21 and the cutting shaft 8 affects their construction effect. Regular cleaning can ensure the normal operation of the shaping wheel 21 and the cutting shaft 8 and improve construction efficiency. In addition, dirt and debris on the surfaces of the shaping wheel 21 and the cutting shaft 8 may cause problems such as unstable sliding and jamming of the equipment. Cleaning can ensure the stability of the equipment and construction safety. Furthermore, debris on the surfaces of the shaping wheel 21 and the cutting shaft 8 may be introduced into the surrounding environment. Cleaning can reduce environmental pollution and impact.In summary, the rotation of the fixed rod 19 and the swing arm 3 positions the shaping wheel 21 and the cutting shaft 8 inside the cleaning groove 2302. Relative motion is generated between the shaping wheel 21 and the cutting shaft 8 and the cleaning bristles 2303, which cleans the surfaces of the shaping wheel 21 and the cutting shaft 8. This thoroughly cleans the equipment, extends its service life, improves work efficiency, ensures construction safety, and reduces environmental impact, offering significant benefits for pipeline laying and related projects.
[0032] Working principle: The user first marks the position of the paving groove on the ground, grasps the handle set on the frame 1, and pushes it in the direction of the marked paving groove. The fork tooth 18 is the first to contact the ground. The fork tooth 18 can remove large particles of impurities in the soil, so that the large particles of impurities float on the soil surface, and loosen the soil texture.
[0033] The loosened soil, under the rotation of the mounting shaft 5, drives the digging shaft 8, which breaks up the loosened soil to form a paving groove on the ground surface. This ensures that the depth and width of the paving groove are uniform, thus guaranteeing the quality and stability of the drainage pipe. In addition, the digging shaft 8 can rotate on the mounting shaft 5 via the first drive motor 7, which can crush large particles of impurities.
[0034] After the laying trench is formed, the inner wall of the laying trench is compacted by the shaping wheel 21, which can effectively solidify the laying trench. Finally, the pipe is placed inside the laying trench, and the pipe is assembled and adjusted. Finally, soil is backfilled on the pipe to achieve the laying function of the pipe.
[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
