Description

Technical Field

[0001] This invention relates to the field of civil engineering equipment technology, and in particular to an automatic crack monitoring and grouting repair device. Background Technology

[0002] Cracks are a common quality defect in engineering structures, especially at the joints between two structural elements. These joints, subjected to long-term loads, environmental effects, and material aging, are highly susceptible to cracking over time. Taking bridge engineering as an example, the connection between the concrete arch foot and the steel arch is a critical part of the bridge structure, achieved through concrete pouring. However, in actual use, due to various factors such as temperature changes, load effects, and material shrinkage, the concrete at the joint is prone to cracking. This not only reduces the reliability of the connection but also poses serious safety hazards, becoming a significant factor affecting the durability and safety of the bridge structure.

[0003] When cracks develop to a certain extent, if timely intervention and repair are not carried out, they may lead to further deterioration of structural performance and even cause safety accidents. Currently, commonly used crack repair methods mainly include the following:

[0004] Grouting: This method involves injecting a bonding and sealing material into the cracks to restore the integrity and airtightness of the structure.

[0005] Grooving method: Grooves of a certain width are cut on both sides of the crack, and then repair material is filled in to improve the repair effect.

[0006] Surface sealing method: Apply a layer of sealant to the surface of the crack to prevent moisture and harmful substances from penetrating into the crack.

[0007] Although these traditional methods can repair cracks to some extent, they generally have the following drawbacks:

[0008] Manual operation: requires a large number of people to operate, is labor-intensive, and is difficult to operate.

[0009] Time-consuming: The process of crack detection, repair plan formulation and implementation is complicated and time-consuming.

[0010] Low efficiency: Manual operation has limited precision, making it difficult to guarantee repair quality and resulting in low efficiency.

[0044] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

Therefore, they should not be construed as limitations on this application.

[0046] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0047] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0048] To better understand the purpose, structure, and function of this invention, the invention will be described in further detail below with reference to the accompanying drawings.

[0049] like Figures 1 to 4 A specific embodiment of an automatic crack monitoring and grouting repair device is shown, wherein the outer shell 1 is attached to the component 1 (not shown in the figure), the outer shell 2 is attached to the component 2 (not shown in the figure), the outer shell 2 is fitted inside the outer shell 1, and the two are slidably connected. When a crack occurs between the component 1 and the component 2, the outer shell 1 and the outer shell 2 slide relative to each other, and the distance of the slide is the crack width.

[0050] Specifically, the amplification assembly includes a rack 6, a first gear 7, a first gear shaft 8, a second gear 9, a second gear shaft 10, a take-up disc 11, and a connecting rod 12. The rack 6 is fixed to the bottom of the second outer shell 2. The first gear 7 is connected to the first outer shell 1 via the first gear shaft 8 and meshes with the rack 6. The second gear 9 is connected to the first outer shell 1 via the second gear shaft 10. The radius of the first gear 7 is larger than the radius of the second gear 9, and the first gear 7 meshes with the second gear 9. The second gear 9 and the take-up disc 11 are fixed together via the connecting rod 12 to achieve synchronous rotation of the take-up disc 11 and the second gear 9. The take-up disc 11 is connected to the beginning of the insulating tape 14.

[0051] Specifically, when gear 29 rotates, the winding disc 11 will rotate synchronously at the same angular velocity. That is, the rotational angular velocity of the winding disc 11 is greater than that of gear 17, and its radius is also larger. Therefore, when a crack occurs, the distance that the winding disc 11 rotates, that is, the length that the insulating tape 14 is pulled, is greater than the crack width, thereby improving the accuracy of the device.

[0052] Specifically, such as Figure 3 and Figure 4 As shown, the power supply assembly includes a tape 13, an insulating tape 14, a power supply device 15, a support rod 17, and two current contact points 22. The insulating tape 14 is wound around the tape 13. The power supply device 15 is installed inside a support housing. The support housing of the power supply device 15 is installed inside an outer casing 1 via the support rod 17. The tape 13 is installed inside the power supply device 15. The two current contact points 22 are located inside the power supply device 15, on the upper and lower sides of the insulating tape 14, respectively. The insulating tape 14 has holes to allow the two current contact points 22 to make contact and conduct electricity.

[0053] Specifically, the grouting assembly includes a material cylinder 18, a support rod 19, and an automatic grouting mechanism; the material cylinder 18 can heat the internal material; the material cylinder 18 is fixed to the outer shell 1 by the support rod 19; the bottom of the material cylinder 18 is provided with an automatic grouting mechanism.

[0054] Specifically, the insulating tape 14 has pre-drilled holes according to the crack width limit and the gear magnification factor. The insulating tape 14 is initially wound onto the winding tape 13, with its end connected to the winding disc 11 and passing between two current contact points 22. When a crack occurs, the winding disc 11 rotates, pulling the insulating tape 14 and winding it into the disc. When the crack width has not reached the limit, the device is not energized as the insulating tape 14 remains between the current contact points 22. When the crack width limit is reached, the holes on the insulating tape 14 are precisely between the current contact points 22, at which point the current contact points 22 make contact, and the device is energized. The material cylinder 18 contains repair material such as asphalt, which is solid at room temperature and does not flow. The power supply device 15 is electrically connected to the material cylinder 18. When the crack width reaches the limit, the device is energized, and the material cylinder 18 begins to heat. As the temperature rises, the internal repair material gradually becomes liquid. An automatic grouting mechanism controls the outflow of the repair material to repair the crack.

[0055] In this way, such as Figure 4 As shown, the expansion of the crack is linked to the pulling of the insulating tape 14. When the crack does not reach the limit, the insulating tape 14 is located between the current contact points 22, the device is de-energized, and the repair material is solid. When the crack reaches the limit, the pores on the insulating tape 14 are located between the current contact points 22, the device is automatically energized, and the material cylinder 18 heats the repair material into a liquid state to repair the crack. This achieves the effect of monitoring the crack width and automatically repairing it when the limit is reached.

[0056] In other preferred embodiments, such as Figure 5As shown, the automatic grouting mechanism includes a valve housing 30, a grouting port 20, a float 21, a bolt 23, a connecting rod 24, a bolt 25, a push rod 26, a piston 27, a slider 28, and a groove 29. The valve housing 30 has a grouting port 20 at its bottom. A piston 27 is slidably connected inside the valve housing 30. A push rod 26 is connected to the side of the piston 27 away from the grouting port 20. A slider 28 is provided at the end of the push rod 26 away from the piston 27. A groove 29 is provided on the connecting rod 24. The connecting rod 24 and the push rod 26 are connected to the slider 28 via the groove 29. The connecting rod 24 is fixed to the valve housing 30 by bolts 25. The float 21 is fixed to the connecting rod 24 by bolts 25, and the angle between the float 21 and the connecting rod 24 is fixed.

[0057] Specifically, when a crack exists, the float 21 at the bottom of the material cylinder droops, and the piston 27 is located outside the grouting port 20. The grouting port 20 opens, and liquid material is injected into the crack through it. As material is injected, the liquid level rises, the float 21 rises, and the connecting rod 24 rotates around the bolt 25. The slider 28 slides within the groove 29, pushing the push rod 26 inward, which in turn pushes the piston 27 inward. When the crack is filled, the grouting port 20 is blocked by the piston 27, and grouting stops. This method monitors the height of the grouting liquid through the float 21, which is linked to the opening and closing of the grouting port 20, thereby accurately controlling the amount of repair material injected and avoiding waste.

[0058] In other preferred embodiments, the inner sides of the outer shell 1 are provided with sliding grooves 3; the inner sides of the outer shell 2 are provided with sliding rails 4; the sliding grooves 3 and the sliding rails 4 cooperate with each other; the outer shell 2 is provided with a sliding rod 5; the outer shell 1 is provided with a circular opening; the sliding rod 5 and the circular opening cooperate with each other to realize that the outer shell 1 and the outer shell 2 can slide.

[0059] In other preferred embodiments, the material cylinder 18 is heated by a spiral heating wire.

[0060] Specifically, a spiral heating wire is used to heat the material, which has high heating efficiency and uniform temperature. It can quickly heat solid repair materials to a liquid state, shorten the grouting time, and improve repair efficiency.

[0061] In other preferred embodiments, the top of the material cylinder 18 is provided with an exhaust port.

[0062] Specifically, the top of the material cylinder 18 is equipped with an exhaust hole, which can effectively discharge the gas generated during the heating process, avoid air bubbles from affecting the grouting effect, and ensure the compactness of the repair material.

[0063] In other preferred embodiments, the insulating tape 14 may have multiple holes.

[0064] Specifically, multiple holes can be drilled in the insulating tape 14 to allow for multiple repairs of the crack.

[0065] In other preferred embodiments, the support rod 17 is integrally connected to the support housing of the power supply device 15, and integrally or threadedly connected to the outer shell 1; the support rod 19 is integrally connected to the material cylinder 18, and integrally or threadedly connected to the outer shell 1, which improves the structural strength and stability of the device and ensures the safe and reliable operation of the device.

[0066] In other preferred embodiments, the power supply device 15 is connected to the material cylinder 18 via a wire 16. The connection method is flexible and facilitates the installation and maintenance of the device.

[0067] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. Furthermore, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
