Abstract
Description
Technical Field
[0001] This application belongs to the field of pipeline maintenance technology, specifically relating to a component for adjusting the amount of resin curing injection in drainage pipelines. Background Technology
[0002] Localized resin curing technology is widely used in the maintenance and repair of urban drainage pipelines. This technology involves injecting resin material into the inner wall of the pipeline, utilizing the curing properties of the resin to form a robust lining, thereby repairing cracks, corrosion, and other problems in the pipeline and extending its service life.
[0003] The resin injection volume refers to the quantitative amount of resin material delivered from the storage tank to the discharge equipment. Specifically, it is the volume or weight of resin precisely transferred from the storage tank to the discharge equipment per unit time or in a single operation via a specific delivery device (such as a pump or pressure system). This process requires strict control to ensure that the resin is injected evenly and accurately into the target area as designed, thereby guaranteeing the consistency of the curing effect and the quality of the repair.
[0004] The inventors discovered that due to the high viscosity and poor fluidity of the resin, unstable flow or local stagnation is likely to occur during transportation. This leads to uneven distribution of the resin on the inner wall of the pipe, with excessive resin accumulation in some areas and insufficient resin in others, thus affecting the thickness of the lining and the quality of the repair after curing. Utility Model Content
[0005] This application provides a resin curing injection volume adjustment component for drainage pipes, which aims to solve the technical problem of inaccurate injection volume caused by poor resin fluidity in the prior art, so as to achieve precise control of the resin injection process, ensure uniform resin distribution, thereby improving the efficiency and quality of pipe repair, and providing more reliable technical support for the maintenance of urban drainage pipes.
[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0007] A component for adjusting the amount of resin curing injection in a drainage pipe is provided, comprising:
[0008] A base for fixing on a horizontal surface; the base has two support plates arranged side by side in the horizontal direction, and a top plate located on the upper side of the base and connected to the two support plates, and the top plate has a feed inlet and a push outlet that pass through in the vertical direction;
[0009] A turntable is rotatably disposed between the top plate and the base, and is connected to a rotation drive component for driving its rotation; the turntable has a plurality of mounting holes that are through in the vertical direction and spaced apart in the circumferential direction, each mounting hole being adapted to communicate with the feed inlet and the push outlet, and each mounting hole having a metering tube inserted into it and connected to the lower side of the top plate;
[0010] A positioning plate is slidably disposed between the turntable and the base in a vertical direction, and has a locking structure with one or two of the support plates so that the upper side of the positioning plate abuts against the lower end face of the metering tube; the positioning plate has a discharge port that runs vertically through and is coaxially disposed with the push port; and
[0011] A piston is slidably disposed in the push port in the vertical direction, and is driven by a linear drive component for moving it, so that the piston extends out of the push port into the metering tube; and when the piston enters the metering tube, the outer circumferential surface of the piston contacts the inner circumferential surface of the metering tube, so that when the piston moves, it pushes the material in the metering tube to the discharge port.
[0012] In one possible implementation, the top plate also has a reserved hole that runs through the vertical direction; the reserved hole is located at the center between the feed port and the push port, the upper side of the turntable has a convex shaft that extends through the reserved hole, and the rotation drive component is a rotating motor that is fixedly mounted on the upper side of the top plate and is drivenly connected to the convex shaft.
[0013] In one possible implementation, the upper side of the turntable is provided with a plurality of sinking grooves that correspond one-to-one with the plurality of mounting holes, and the upper end of the metering tube has a limiting part that extends radially outward and is adapted to abut against the bottom of the sinking groove.
[0014] In one possible implementation, the piston further includes:
[0015] An elastic collar is fixedly sleeved on the outer periphery of the piston and is adapted to abut against the inner peripheral wall of the push port and the metering tube;
[0016] When the outer peripheral wall of the elastic collar abuts against the inner peripheral wall of the feed port and the inner peripheral wall of the metering tube, the elastic collar undergoes elastic deformation.
[0017] In one possible implementation, the locking structure includes:
[0018] Multiple positioning holes are spaced apart on the support plate in the vertical direction;
[0019] A positioning nut, fixedly mounted on the positioning plate and adapted to communicate with any one of the positioning holes; and
[0020] A stop bolt, adapted to be inserted into any of the positioning holes and adapted to be threadedly connected to the alignment nut, to restrict movement of the positioning plate relative to the support plate.
[0021] In one possible implementation, the positioning plate has a groove suitable for the alignment nut to be inserted, and the bottom of the groove also has a slot suitable for the end of the stop bolt to be inserted.
[0022] In one possible implementation, the upper side of the base is provided with a receiving groove that is coaxially arranged with the discharge port.
[0023] In one possible implementation, the base has an upwardly extending fixed shaft coaxial with the turntable, and the lower side of the turntable is rotatably connected to the upper end of the fixed shaft.
[0024] The positioning plate has a guide hole that runs vertically through the fixed shaft, and a spring is fitted around the fixed shaft on the lower side of the positioning plate. The two ends of the spring abut against the base and the positioning plate, respectively, so as to drive the positioning plate to move upward to abut against the metering tube.
[0025] In one possible implementation, the metering tube has a convex ring extending radially outward therefrom, and the lower side of the convex ring is provided with a plurality of concave ball grooves, and each concave ball groove is provided with a ball.
[0026] Each of the balls extends out of the concave ball groove and is adapted to abut against the upper side of the positioning plate.
[0027] In one possible implementation, the linear drive component is a linear cylinder;
[0028] When the power output end of the linear cylinder retracts, the upper and lower sides of the piston are coplanar with the upper and lower sides of the top plate, respectively.
[0029] In this embodiment, by rotating the turntable to a preset angle using the rotating drive component, the mounting hole and the feed inlet at the corresponding angle can be coaxially aligned, thus connecting the corresponding metering tube to the feed inlet. In this state, the outlet at the lower end of the metering tube is closed by the upper side of the positioning plate, allowing the resin discharged through the feed inlet to collect and fill the inner cavity of the metering tube. After the inner cavity of the metering tube is filled with resin, restarting the rotating drive component moves the next metering tube to a position connected to the feed inlet, and repeating the above process completes the resin feeding.
[0030] Under the same conditions, by rotating the drive component to rotate the turntable to a preset angle, the mounting hole and the push port at the corresponding angle can be set coaxially, so that the corresponding metering tube is connected to the push port and the discharge port; based on this, by driving the piston to move through the linear drive component, the resin in the metering tube can be squeezed and discharged to the outside through the discharge port.
[0031] In the aforementioned process, different injection volumes can be preset by changing the metering tubes of different lengths; correspondingly, the position of the positioning plate can be locked by the locking structure to ensure that the positioning plate abuts against the lower end face of the metering tube, preventing the resin from being discharged from the gap between the positioning plate and the metering tube before entering the discharge port.
[0032] The resin curing injection volume adjustment component for drainage pipes provided in this embodiment can solve the technical problem of inaccurate injection volume caused by poor resin fluidity in the prior art, so as to achieve precise control of the resin injection process, ensure uniform resin distribution, thereby improving the efficiency and quality of pipe repair and providing more reliable technical support for the maintenance of urban drainage pipes.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0049] Please refer to the following: Figures 1 to 10 The resin curing injection volume adjustment component for drainage pipes provided in this application will now be described. The resin curing injection volume adjustment component for drainage pipes proposed in this application includes a base 1, a turntable 2, a positioning plate 3, and a piston 4.
[0050] The base 1 is used to fix it on a horizontal plane. In this embodiment, the base 1 has two support plates 11 arranged side by side in the horizontal direction, and a top plate 12 located on the upper side of the base 1 and connected to the two support plates 11. The top plate 12 has a feed inlet 121 and a pusher 122 that are arranged side by side in the horizontal direction and pass through in the vertical direction.
[0051] The turntable 2 is rotatably mounted between the top plate 12 and the base 1, and is driven by a rotational drive component 10. The turntable 2 has multiple mounting holes 21 that extend vertically and are spaced apart circumferentially. Each mounting hole 21 is adapted to communicate with the inlet 121 and the pusher 122, and a metering tube 5 connected to the lower side of the top plate 12 is inserted into each mounting hole 21. Different lengths of metering tubes 5 can be used to output different resins.
[0052] The positioning plate 3 is slidably disposed between the turntable 2 and the base 1 in the vertical direction, and has a locking structure 6 between it and one or two support plates 11, so that the upper side of the positioning plate 3 abuts against the lower end face of the quantitative tube 5 of different specifications; and the positioning plate 3 has a discharge port 31 that runs through in the vertical direction and is coaxially disposed with the push port 122.
[0053] The piston 4 is slidably disposed in the push port 122 in the up and down direction, and is driven by a linear drive member 20 for moving it, so that the piston 4 extends out of the push port 122 into the metering tube 5; and when the piston 4 enters the metering tube 5, the outer peripheral surface of the piston 4 contacts the inner peripheral surface of the metering tube 5, so that when the piston 4 moves, it pushes the material in the metering tube 5 to the discharge port 31.
[0054] In this embodiment, by rotating the drive component 10 to rotate the turntable 2 to a preset angle, the mounting hole 21 and the inlet 121 at the corresponding angle can be coaxially arranged, so that the corresponding metering tube 5 is connected to the inlet 121. In this state, the outlet at the lower end of the metering tube 5 is closed by the upper side of the positioning plate 3, so that the resin discharged through the inlet 121 can be collected and fill the inner cavity of the metering tube 5. After the inner cavity of the metering tube 5 is filled with resin, the drive component 10 is restarted again, so that the next metering tube 5 can be moved to the position connected to the inlet 121. Repeating the above process can complete the resin feeding.
[0055] Under the same conditions, by rotating the drive member 10 to rotate the turntable 2 to a preset angle, the mounting hole 21 and the push port 122 at the corresponding angle can be set coaxially, so that the corresponding metering tube 5 is connected to the push port 122 and the discharge port 31; based on this, by driving the piston 4 to move through the linear drive member 20, the resin in the metering tube 5 can be squeezed and discharged to the outside through the discharge port 31.
[0056] In the aforementioned process, different injection volumes can be preset by replacing the metering tubes 5 of different lengths; correspondingly, the position of the positioning plate 3 can be locked by the locking structure 6 to ensure that the positioning plate 3 abuts against the lower end face of the metering tube 5, preventing the resin from being discharged from the gap between the positioning plate 3 and the metering tube 5 before entering the discharge port 31.
[0057] The resin curing injection volume adjustment component for drainage pipes provided in this embodiment can solve the technical problem of inaccurate injection volume caused by poor resin fluidity in the prior art, so as to achieve precise control of the resin injection process, ensure uniform resin distribution, thereby improving the efficiency and quality of pipe repair and providing more reliable technical support for the maintenance of urban drainage pipes.
[0058] In some embodiments, such as Figure 7 and Figure 9 As shown, the top plate 12 also has a reserved hole 123 that runs through the vertical direction; the reserved hole 123 is located at the center between the feed inlet 121 and the pusher inlet 122, and the upper side of the turntable 2 has a convex shaft 22 that extends through the reserved hole 123, and the rotation drive component 10 is a rotating motor that is fixedly installed on the upper side of the top plate 12 and is connected to the convex shaft 22 for transmission.
[0059] In some embodiments, such as Figure 7 and Figure 10 As shown, the upper side of the turntable 2 is provided with multiple sinking grooves 23 that correspond one-to-one with multiple mounting holes 21. The upper end of the metering tube 5 has a limiting part 51 that extends radially outward and is suitable for abutting the bottom of the sinking groove 23, so as to facilitate the combination of the positioning tube 5 and the turntable 2.
[0060] In some embodiments, such as Figure 8 As shown, the piston 4 also includes an elastic collar 41, which is fixedly sleeved on the outer periphery of the piston 4 and is adapted to abut against the inner peripheral wall of the feed port 122 and the metering tube 5.
[0061] By adopting the above technical solution, when the outer peripheral wall of the elastic collar 41 abuts against the inner peripheral wall of the push port 122 and the inner peripheral wall of the metering tube 5, the elastic collar 41 undergoes elastic deformation to ensure full contact with the inner peripheral wall of the push port 122 and the inner peripheral wall of the metering tube 5 and complete ejection of the resin.
[0062] In some embodiments, such as Figure 4 and Figure 5 As shown, the locking structure 6 includes multiple positioning holes 61, alignment nuts 62, and stop bolts 63.
[0063] Multiple positioning holes 61 are spaced apart on the support plate 11 in the vertical direction, and the axial direction of each positioning hole 61 is parallel to the arrangement direction of the two support plates 11.
[0064] The alignment nut 62 is fixedly mounted on the positioning plate 3; as the positioning plate 3 moves longitudinally, the alignment nut 62 can communicate with any of the positioning holes 61.
[0065] The stop bolt 63 is adapted to be inserted into either of the positioning holes 61 and to be threadedly connected to the alignment nut 62 to restrict the movement of the positioning plate 3 relative to the support plate 11.
[0066] In some embodiments, such as Figure 4 and Figure 5 As shown, the positioning plate 3 has a groove 32 suitable for the insertion of the alignment nut 62, and the bottom of the groove 32 also has a slot 33 suitable for the insertion of the end of the stop bolt 63, so as to ensure the full connection between the stop bolt 63 and the alignment nut 62.
[0067] In some embodiments, such as Figure 3 and Figure 9 As shown, the upper side of the base 1 is provided with a receiving groove 13 coaxially arranged with the discharge port 31. This receiving groove 13 is used to receive containers or temporarily store resin.
[0068] In some embodiments, such as Figure 1 , Figure 6 and Figure 9 As shown, the base 1 has a fixed shaft 14 that extends upward and is coaxial with the turntable 2, and the lower side of the turntable 2 is rotatably connected to the upper end of the fixed shaft 14 to enhance the rotational connection strength between the turntable 2 and the top plate 12.
[0069] The positioning plate 3 has a guide hole 34 that runs through the vertical direction and is suitable for the fixed shaft 14 to pass through. The lower side of the positioning plate 3 has a spring 7 that is sleeved on the outer periphery of the fixed shaft 14. The two ends of the spring 7 abut against the base 1 and the positioning plate 3 respectively, so as to drive the positioning plate 3 to move upward to abut against the metering tube 5, so as to connect the positioning plate 3 and the support plate 11 through the locking structure 6.
[0070] In some embodiments, such as Figure 10 As shown, the metering tube 5 has a convex ring portion 52 extending outward along its radial direction. The lower side of the convex ring portion 52 is provided with a plurality of concave ball grooves 521, and each concave ball groove 521 is provided with a ball 522.
[0071] In actual use, each ball 522 extends to the outside of the concave ball groove 521 and is adapted to abut against the upper side of the positioning plate 3, thereby ensuring the smooth rotation of the positioning tube 5 with the turntable 2.
[0072] In some embodiments, such as Figure 8 As shown, the linear drive component 20 is a linear cylinder.
[0073] Compared to other devices that can achieve linear drive, the shortest stroke of the linear cylinder is a fixed value; that is, when the power output end of the linear cylinder retracts, the upper and lower sides of the piston 4 are coplanar with the upper and lower sides of the top plate 12, thereby ensuring that the piston 4 is reset.
[0074] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
