Description

Technical Field

[0001] This application relates to the technical field of grouting machines, and in particular to a water-curing propylene grouting machine. Background Technology

[0002] Currently, grouting technology is widely used in civil engineering, foundation reinforcement, tunnel construction, crack repair, and waterproofing projects as an efficient and economical reinforcement and waterproofing method. Water-cured propylene grouting materials are gradually becoming the preferred material in grouting projects due to their rapid curing, high strength, excellent waterproofing performance, and environmentally friendly characteristics.

[0003] In traditional grouting machines, before injecting water to cure the acrylic grouting material, the grouting pipe is connected to the grout outlet pipe on the grouting machine body. The grouting pipe is a PVC flexible hose, and a gasket is placed at the end of the grouting pipe and directly inserted into the grout outlet pipe before grouting begins.

[0004] With the continuous use of grouting machines, traditional gaskets, which consist of only one layer, are prone to leakage after wear. Utility Model Content

[0005] To reduce leakage, this application provides a water-curing propylene grouting machine.

[0006] The water-curing propylene grouting machine provided in this application adopts the following technical solution:

[0007] A water-curing propylene grouting machine includes a main body with a grout outlet pipe connected to it. A grouting pipe is connected to the end of the grout outlet pipe away from the main body. A grout outlet cap connects the grout outlet pipe and the grouting pipe. One end of the grout outlet cap is fitted over the end of the grout outlet pipe and threaded to the outer wall of the grout outlet pipe. The other end of the grout outlet cap is inserted into one end of the grouting pipe. A sealing gasket assembly is placed inside the grout outlet cap. Along the direction away from the grout outlet pipe, the inner diameter of the internal passage of the grout outlet cap decreases to press the sealing gasket assembly closer to the grouting pipe. The sealing gasket assembly includes a first gasket, a second gasket, and a third gasket. A first annular groove is formed on the circumferential outer wall of the first gasket. The second gasket is looped around the outer wall of the first gasket and located within the first annular groove. The third gasket abuts against the side wall of the first gasket. The side wall of the first gasket away from the third gasket abuts against the end face of the grout outlet pipe. The circumferential outer walls of the first, second, and third gaskets abut against the inner walls of the corresponding internal passages of the grout outlet caps.

[0008] By adopting the above technical solution, as the grouting machine is used continuously, the grout washes over the sealing gasket assembly, causing wear on the sealing gasket assembly. At this time, by further tightening the grout outlet cap, the sealing gasket assembly is pressed closer to the grouting pipe, thus ensuring the sealing degree again and reducing the occurrence of leakage.

[0009] Optionally, the sealing gasket assembly further includes a fourth gasket and a fifth gasket. A second annular groove is formed on the circumferential outer wall of the fifth gasket. The fourth gasket is looped around the outer wall of the fifth gasket and located in the second annular groove. The fifth gasket abuts against the side wall of the third gasket away from the first gasket.

[0010] By adopting the above technical solution, the thickness of the sealing gasket assembly is further increased, thereby ensuring that the sealing gasket assembly has sufficient compression in the direction close to the grouting pipe after wear.

[0011] Optionally, the second and fourth washers are made of soft rubber.

[0012] By adopting the above technical solution, the second and fourth gaskets are made of soft rubber gaskets, which ensures the elasticity of the sealing gasket assembly and further improves the compression of the sealing gasket assembly in the direction close to the grouting pipe after wear.

[0013] Optionally, a rotating head is rotatably connected to the end of the slurry outlet cap away from the slurry outlet pipe. The center line of the rotating head coincides with the center line of the slurry outlet cap, and the end of the rotating head away from the slurry outlet cap is inserted into one end of the slurry outlet pipe.

[0014] By adopting the above technical solution, when the grouting pipe adjusts the grouting position, the rotating head swings accordingly to adjust the angle, reducing the occurrence of the grouting pipe and rotating head becoming disconnected due to the swinging of the grouting pipe.

[0015] Optionally, a fastening assembly is provided on the outer wall of the rotating head. The fastening assembly includes a strap, a vertical plate, a check strip, and a coil spring. The vertical plate is slidably disposed on the outer wall of the rotating head and slides horizontally in the direction close to or away from the rotating head. One end of the strap is fixedly connected to the inner wall of the vertical plate facing the rotating head, and the other end passes through the vertical plate after passing around the outer wall of the grouting pipe. The check strip is rotatably disposed on the side wall of the vertical plate away from the rotating head. The check strip is used to limit the retraction of the strap. The coil spring is disposed on the rotation axis of the check strip and is used to push the check strip to move in the direction close to the strap.

[0016] By adopting the above technical solution, in order to reduce the occurrence of grouting pipe detachment when the grouting pressure changes, after the grouting pipe is inserted and connected to the rotating head, the connection between the grouting pipe and the rotating head is wrapped with a strap and a reinforcing bar is tied. The strap can be pulled in one direction. The check strip restricts the return of the strap, thereby achieving the binding effect. When you want to untie it, you can manually push the check strip away from the strap.

[0017] Optionally, a protrusion is fixed on the side of the vertical plate near the rotating head, and a groove is provided on the protrusion. The fixing point of the strap to the vertical plate and the point where the strap passes through the vertical plate are both located in the groove.

[0018] By adopting the above technical solution, the protrusions abut and squeeze the areas at both ends of the binding strap that are not tightly bound to the grouting pipe, thereby improving the binding effect of the binding strap on the grouting pipe.

[0019] Optionally, a third annular groove is provided on the outer wall of the rotating head, the third annular groove is positioned opposite the protrusion, and the third annular groove is formed around the outer wall of the rotating head.

[0020] By adopting the above technical solution, the third annular groove provides space for the strap and the protrusion.

[0021] Optionally, a horizontal plate is fixed on the rotating head. The horizontal plate is horizontally arranged and has a sliding groove. The sliding groove is opened in the direction close to or away from the rotating head. The bottom end of the vertical plate is inserted into the sliding groove and slides along the length of the sliding groove. A screw is rotatably arranged on the horizontal plate. The screw passes through the vertical plate and is threadedly connected to the vertical plate.

[0022] By adopting the above technical solution, rotating the screw can adjust the position of the vertical plate on the horizontal plate, thereby adjusting the distance between the vertical plate and the rotating head. When the binding strap is binding the grouting pipe, the vertical plate is moved synchronously towards the grouting pipe, so that the protrusion is inserted into the third annular groove, thus completing the binding strap binding the grouting pipe.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The sealing gasket assembly ensures a tight seal after prolonged use of the grouting machine; simply tighten the grout outlet cap again.

[0025] 2. The fastening components ensure the firmness of the connection between the grouting pipe and the rotating head, reducing the occurrence of grouting pipe detachment. Attached Figure Description

[0030] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0031] This application discloses a water-curing propylene grouting machine.

[0032] refer to Figure 1 and Figure 2 A water-curing propylene grouting machine includes a body 1, with a grout outlet pipe 11 connected to the body 1. A grout injection pipe 12 is provided at the end of the grout outlet pipe 11 away from the body 1, and a grout outlet cap 2 is connected between the grout injection pipe 12 and the grout outlet pipe 11. One end of the grout outlet cap 2 covers the end of the grout outlet pipe 11 away from the body 1, and the grout outlet cap 2 is threadedly connected to the outer wall of the grout outlet pipe 11. A rotating head 4 is rotatably connected to the other end of the grout outlet cap 2. The end of the rotating head 4 away from the grout outlet cap 2 is inserted into one end of the grout injection pipe 12. At this time, the grout outlet pipe 11, the grout outlet cap 2, the rotating head 4, and the interior of the grout injection pipe 12 are all connected to form a normal grout outlet passage.

[0033] refer to Figure 1 and Figure 2 The discharge cap 2 contains a sealing gasket assembly 3, which includes a first gasket 31, a second gasket 32, a third gasket 33, a fourth gasket 34, and a fifth gasket 35. The first gasket 31 has a first annular groove 311 on its circumferential outer wall, extending around its entire circumference. The fifth gasket 35 has a second annular groove 351 on its circumferential outer wall, extending around its entire circumference. The second gasket 32 ​​is fitted around the outer wall of the first gasket 31 and located within the first annular groove 311, while the fourth gasket 34 is fitted around the outer wall of the fifth gasket 35 and located within the second annular groove 351. The sealing gasket assembly 3 is arranged in the following order from top to bottom inside the slurry outlet cap 2: the fifth gasket 35, the third gasket 33, and the first gasket 31, which abut against each other. The side wall of the first gasket 31 away from the third gasket 33 abuts against the end face of the slurry outlet pipe 11 away from the body 1. The side wall of the fifth gasket 35 away from the third gasket 33 abuts against the inner wall of the slurry outlet cap 2.

[0034] refer to Figure 1 and Figure 2Along the direction away from the grout outlet pipe 11, the inner diameter of the internal passage of the grout outlet cap 2 decreases. In this embodiment, there is only one reduction in diameter. The necking point is where the side wall of the fifth washer 35 away from the third washer 33 abuts against the inner wall of the grout outlet cap 2. When the sealing washer assembly 3 wears down, the grout outlet cap 2 is tightened downwards. The inner wall of the grout outlet cap 2 exerts pressure on the sealing washer assembly 3 towards the grouting pipe 12, further compressing the sealing washer assembly 3. The circumferential outer wall of the sealing washer assembly 3 abuts against the inner wall of the grout outlet cap 2, that is, the circumferential outer walls of the first washer 31, the second washer 32, the third washer 33, the fourth washer 34, and the fifth washer 35 all abut against the inner wall of the grout outlet cap 2.

[0035] refer to Figure 2 The second washer 32 and the fourth washer 34 are made of soft rubber. The first washer 31, the third washer 33 and the fifth washer 35 have a higher hardness than the second washer 32 and the fourth washer 34.

[0036] refer to Figure 2 and Figure 3 The centerline of the rotating head 4 coincides with the centerline of the discharge cap 2, meaning the rotating head 4 rotates relative to the discharge cap 2. A horizontal plate 7 and a fastening assembly 5 are provided on the outer wall of the rotating head 4. The fastening assembly 5 includes a strap 51, the horizontal plate 7, a check strip 53, and a coil spring 54. The horizontal plate 7 is horizontally positioned, with one end fixedly connected to the outer wall of the rotating head 4. A groove 71 is provided on the top surface of the horizontal plate 7, extending towards or away from the rotating head 4. A screw 72 is rotatably mounted on the horizontal plate 7, rotating relative to the horizontal plate 7. One end of the screw 72 passes through a vertical plate 52, which is vertically positioned. The bottom end of the vertical plate 52 is inserted into the groove 71 and slides along the length of the groove 71.

[0037] refer to Figure 2 and Figure 3A protrusion 6 is fixed on the side wall of the vertical plate 52 near the rotating head 4. A third annular groove 41 is formed on the outer wall of the rotating head 4, and the third annular groove 41 is formed around the circumference of the outer wall of the rotating head 4. The protrusion 6 is positioned directly opposite the third annular groove 41. A groove 61 is formed on the side wall of the protrusion 6 facing the rotating head 4, and the groove 61 is positioned horizontally. One end of the binding strap 51 is fixedly connected to the protrusion 6, and the fixing point is located in the groove 61. The other end of the binding strap 51 wraps around the grouting pipe 12 and passes through the vertical plate 52 to the side of the vertical plate 52 away from the rotating head 4. The point where the binding strap 51 passes through the vertical plate 52 is located in the groove 61. The check bar 53 and the coil spring 54 are both located on the side wall of the vertical plate 52 away from the rotating head 4. The check bar 53 is rotatably mounted on the vertical plate 52 with its rotation axis set horizontally. The coil spring 54 is located on the rotation axis of the check bar 53. One end of the coil spring 54 is fixedly connected to the check bar 53, and the other end is fixedly connected to the vertical plate 52. The rebound force of the coil spring 54 pushes the check bar 53 to rotate toward the point where the strap 51 passes through the vertical plate 52. The check bar 53 abuts against the strap 51, restricting the strap 51 from retracting to the side of the vertical plate 52 near the rotating head 4.

[0038] The implementation principle of a water-curing propylene grouting machine according to an embodiment of this application is as follows: one end of the grouting pipe 12 is inserted into the rotating head 4, and then the binding strap 51 is pulled around the outer wall of the grouting pipe 12 and passes through the vertical plate 52. While tightening the binding strap 51, the vertical pipe is moved towards the grouting pipe 12 until the protrusion 6 is inserted into the third annular groove 41. As the grouting machine is used continuously, the grout washes the sealing gasket assembly 3, and the sealing gasket assembly 3 is worn. At this time, by further tightening the grouting cap 2, the sealing gasket assembly 3 is pressed towards the grouting pipe 12, thus ensuring the sealing degree again and reducing the occurrence of leakage.

[0039] The embodiments described in this specific implementation are 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.
