Description

Technical Field

[0001] This utility model relates to the field of pipeline repair technology, specifically to a CIPP hose grouting and compaction device. Background Technology

[0002] CIPP is a trenchless pipeline repair technology that repairs damaged pipelines by installing a flexible inner liner inside the existing pipeline, which then hardens to form a new inner wall. The repair process is quick and has minimal environmental impact. During the operation, under water or air pressure, a specially designed polyester felt resin liner is laid onto the inner surface of the existing pipeline and tightly adheres to the original pipeline wall, achieving the purpose of pipeline repair.

[0003] During hose processing, before grouting and compaction, the inside of the hose must first be vacuumed to prevent air bubbles, ensure a tight bond between the resin material and the hose, improve impregnation, and enhance the strength of the lining. However, in actual operation, because the inner layer of the hose is mostly made of fiberglass felt, the special properties of the material result in gaps and burrs in the inner layer. This makes it difficult to achieve a good vacuum effect when vacuuming from the end, leading to low work efficiency and incomplete impregnation of the resin material. After curing, this affects the quality and strength of the lining layer, indicating room for technical improvement. Utility Model Content

[0004] This invention aims to solve the technical problem mentioned above, where gaps and burrs exist in the inner layer of the hose, making it difficult to achieve a good vacuum effect when vacuuming from the end. It provides a CIPP hose grouting and compaction device.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a CIPP hose grouting and compaction device, including a support frame, an inclined conveyor belt and a driving device on the support frame, wherein the hose can be conveyed from low to high on the conveyor belt; further comprising:

[0006] A compaction assembly; including a compaction roller mounted on a support frame at a higher end, the compaction roller being movable up and down above a hose; and a vacuum pump connected to the hose;

[0007] Grouting assembly; including an injection head located at the end of a hose away from the vacuum pump; a clamping element located on the outside of the hose near the injection head;

[0008] A vacuum assembly includes a second conveyor belt and its driving device mounted on a support frame and positioned below the second conveyor belt. An auxiliary flattening structure is fixedly mounted on the support frame and positioned above the second conveyor belt. The auxiliary flattening structure includes an outer protective box, in which a squeezing roller is movably mounted. The inner bottom surface of the outer protective box slopes downward from one end near the vacuum pump to the other end.

[0009] Furthermore, the higher end of the support frame is provided with a cross brace, and an electric push rod is provided on the cross brace. The output end of the electric push rod extends into the cross brace and is connected to the rolling roller.

[0010] Furthermore, both sides of the outer protective box are provided with through grooves that can accommodate hoses, and the hoses can pass through the outer protective box from the lower end of the extrusion roller; the front and rear ends of the extrusion roller are rotatably provided with extension threaded shafts, and the extension threaded shafts extend out of the outer protective box and are locked with nuts; the front and rear ends of the outer protective box are provided with strip grooves that can slide with the extension threaded shafts.

[0011] Furthermore, the vacuum pump is connected to the hose near its end, and the corresponding end is sealed.

[0012] Furthermore, the injection head is funnel-shaped and detachable; the clamping component includes two elongated metal pressure plates located at the upper and lower ends of the hose, respectively. Both ends of the metal pressure plates are provided with threaded holes, and the corresponding threaded holes are detachably connected by a screw and a wing nut.

[0013] Furthermore, the support frame is provided with mounting strips on both the front and rear sides and on the outer sides of the transmission belt; the lower end of the auxiliary flattening structure is fixedly connected to the corresponding mounting strip.

[0014] Furthermore, a guide frame is provided on one side of the support frame; the guide frame includes two symmetrical uprights, and two guide rollers are rotatably arranged between the uprights, through which the hose passes when vacuuming.

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] Adding a second conveyor belt below the main conveyor belt allows vacuum grouting and compaction operations to be completed on the same support frame, reducing the need to turn the hoses around and drag them, thus improving work efficiency.

[0017] During vacuuming operations, the hose is pre-compressed, and the degree of compression can be adjusted. After compression, the air is driven to the vacuum machine, which not only improves the vacuuming efficiency but also squeezes out the air in the gaps in the hose lining, reducing air residue and thus preventing air bubbles from forming after grouting, thereby improving the structural strength of the inner lining layer after the flipping construction.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Example 1, in conjunction with Appendix Figure 1 A CIPP hose grouting and compaction device includes a support frame 1, an inclined conveyor belt 2 and a drive device on the support frame 1, and a hose 3 can be conveyed from low to high on the conveyor belt 2; thereby completing the orderly compaction of the hose 3 after grouting, so that the internal resin material is flattened.

[0025] It also includes a compaction assembly 4; including a compaction roller 401 provided on the support frame 1 at the higher end, the compaction roller 401 being able to move up and down above the hose 3;

[0026] Specifically, the higher end of the support frame 1 is provided with a cross brace 403, and an electric push rod 404 is provided on the cross brace 403. The output end of the electric push rod 404 extends into the cross brace 403 and is connected to the crushing roller 401. The electric push rod 404 can drive the crushing roller 401 to move up and down, adjust the distance between it and the hose 3, so that it can play a crushing role without being too tight and causing the hose 3 to break.

[0027] It also includes a vacuum pump 402 connected to the hose 3; the vacuum pump 402 is connected to the hose 3 near the end, and the corresponding end is sealed. The sealing creates a closed space inside the hose 3, which facilitates vacuuming. The sealing can be done by using a highly adhesive engineering tape.

[0028] Example 2, in conjunction with Appendix Figure 2 , 3 4;

[0029] It includes a grouting assembly 5; and an injection head 501 located at the end of the hose 3 away from the vacuum pump 402. The injection head 501 is funnel-shaped and detachable, which enlarges the diameter of the end of the hose 3 to facilitate grouting.

[0030] In addition, a clamping element 502 is provided on the outside of the hose 3 and near the injection head 501; the clamping element 502 includes two long strip metal pressure plates, located at the upper and lower ends of the hose 3 respectively, and both ends of the metal pressure plates are provided with threaded holes, and the corresponding threaded holes are detachably connected by a screw and a wing nut; the clamping element 502 enables grouting to be performed only on a section of the end of the hose 3 during grouting operations, so that it is concentrated, avoids random flow, and facilitates subsequent compaction;

[0031] It also includes a vacuum assembly 6; the vacuum assembly 6 includes a second conveyor belt 601 and its driving device located on the support frame 1 and below the conveyor belt 2, which is used to move the hose 3 during the vacuuming operation to facilitate the air being driven to one end close to the vacuum pump 402.

[0032] An auxiliary flattening structure is fixedly provided on the support frame 1 and above the second conveyor belt 601; specifically, mounting strips 602 are provided on the front and rear sides of the support frame 1 and on the outer side of the second conveyor belt 601; the lower end of the auxiliary flattening structure is fixedly connected to the corresponding mounting strip 602; the auxiliary flattening structure can be fixed above the second conveyor belt 601 and avoid affecting the normal operation of the second conveyor belt 601.

[0033] Specifically, the auxiliary flattening structure includes an outer protective box 603, in which a pressing roller 604 is movably provided, and the inner bottom surface of the outer protective box 603 slopes downward from one end near the vacuum pump 401 to the other end.

[0034] Both sides of the outer protective box 603 are provided with through grooves 605 that can accommodate the hose 3, and the hose 3 can pass through the outer protective box 603 from the lower end of the extrusion roller 604; the front and rear ends of the extrusion roller 604 are rotatably provided with extension threaded shafts 606, and the extension threaded shafts 606 extend out of the outer protective box 603 and are locked with nuts; the front and rear ends of the outer protective box 603 are provided with strip grooves 607 that can slide with the extension threaded shafts 606.

[0035] In the above structure, by releasing the extended threaded shaft 606 so that it can move to the right in the strip groove 607, the distance between the extrusion roller 604 and the inner bottom surface of the outer protective box 603 can be reduced, thereby compressing the space through which the hose 3 can pass. When the hose 3 passes through the outer protective box 603, it can undergo a round of extrusion in advance, squeezing out the air in the gaps in the inner layer of the hose 3 and driving it to the vacuum pump 401, so that the vacuuming effect is better, thereby avoiding the generation of air bubbles after grouting, which would affect the overall structural strength of the hose 3 after it is turned over.

[0036] During operation, after the vacuuming and grouting of the hose 3 are completed, the upper grouting end can be directly extended to the higher end of the conveyor belt 2 for compaction. This reduces the scattered operation links in the existing technology, as well as the twisting, turning and dragging of the hose 3, and improves the degree of integration.

[0037] In addition, a guide frame 7 is provided on one side of the support frame 1; the guide frame 7 includes two symmetrical uprights, and two guide rollers are rotatably arranged between the uprights. When the hose 3 is vacuumed, it passes between the two guide rollers; since the squeeze roller 604 will bring resistance to the hose 3, it is not convenient to move the hose 3 by relying solely on the drive of the conveyor belt 601. It can be squeezed and dragged by the guide roller. In practical applications, the outer side of the guide roller can be set as a protrusion to reduce the contact area between it and the hose 3 and avoid the phenomenon of reverse squeezing of air in the hose 3 caused by full contact.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
