Description

Technical Field

[0001] This invention relates to the field of pavement repair technology, and in particular to a self-healing grouting and curing device for roadbed and pavement cracks. Background Technology

[0002] The self-healing grouting and curing device for roadbed and pavement cracks is a specialized device designed to treat cracks in roadbeds and pavements, enabling them to heal themselves. It primarily works by injecting specific materials into the cracks through grouting and then curing the cracks after injection to promote repair and healing. In actual production, because the size of cracks is not easily controlled, multiple areas of varying widths often exist within a single crack. Current technology, for wider areas (wide cracks), involves directly inserting the grouting nozzle into the crack for grouting. However, for narrower cracks (narrow cracks), the nozzle cannot be inserted, necessitating either placing the nozzle directly above the narrow crack or replacing it with a nozzle of a size specifically designed for narrow cracks.

[0003] However, in practical applications, since the nozzle specifications of the grouting equipment are fixed, the diameter of the nozzle that outputs the grouting material is constant. When the output diameter is larger than the width of the narrow crack, the grouting material output cannot enter the narrow crack as smoothly as it does when entering a wide crack. The grouting material that cannot enter the narrow crack will accumulate around the crack, and the filling material will spread outwards due to its own fluidity, thus affecting the smooth progress of the grouting repair work. As for injection work by changing nozzles, there are even greater drawbacks, because there are often multiple areas of different widths on a crack, so the nozzles need to be changed frequently. This method of operation will greatly increase the workload and seriously delay work efficiency. Summary of the Invention

Detailed Implementation

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Reference Figures 1-13 This invention includes a roadbed and pavement crack self-healing grouting and maintenance device, comprising a grouting machine body 1 and a nozzle body 2 installed below the grouting machine body 1. The nozzle body 2 includes a connecting component 21 communicating with the grouting machine body 1, a driving component 22 sleeved on the lower end of the connecting component 21, a spiral rack 222 with a spiral structure opened on one side of the driving component 22, and a nozzle component 23 inserted into the connecting component 21. The grouting machine body 1 is the main structure of the grouting equipment, and its interior includes, but is not limited to, a raw material tank and a delivery pump. The nozzle body 2 is a nozzle used for spraying. Reference Figure 5 The connecting component 21 includes a receiving pipe 215 sleeved on the top of the nozzle component 23, a receiving groove 216 opened in the receiving pipe 215, a rectangular groove 217 opened at the axial position of the receiving pipe 215 and in the shape of a rectangle, and a limiting pipe 218 fixedly connected to the lower end of the receiving pipe 215, with the rectangular groove 217 passing downward through the limiting pipe 218. At the same time, the driving component 22 is sleeved on the limiting pipe 218. The receiving groove 216 and the rectangular groove 217 are used to provide space for installing the nozzle component 23 and for the nozzle component 23 to move. The limiting pipe 218 is used to install the driving component 22. Reference Figure 11 The nozzle component 23 includes multiple sets of annularly evenly spaced nozzle baffles 231 arranged in a rectangular groove 217. Each set of nozzle baffles 231 has a sealing plate 232 at its top, which is located in the receiving groove 216. Each set of nozzle baffles 231 has a transversely arranged transmission rack 233 on its outer wall, which meshes with a helical rack 222 for transmission. The injection port 234 is composed of multiple sets of nozzle baffles 231 and has a rectangular structure. The four sets of nozzle baffles 231 are distributed in a staggered manner. The injection port 234 is the channel for the sealant to flow outward, and its size is not fixed. The transmission rack 233 can be moved by meshing with the helical rack 222. The transmission racks 233 of the four sets of nozzle baffles 231 are synchronously connected to the helical rack 222, so the four sets of nozzle baffles 231 will move synchronously by being pushed by the helical rack 222.

[0032] Among them, reference Figure 12 and Figure 13Each set of nozzle baffles 231 has a long side 2311 on its inner side and a short side 2312 on the side of the nozzle baffle 231 that is perpendicular to the long side 2311. The injection port diameter 234 is composed of the long side 2311 of multiple sets of nozzle baffles 231, and the short side 2312 on each set of nozzle baffles 231 abuts against the long side 2311 of another set of nozzle baffles 231.

[0033] Among them, reference Figure 5 The connecting component 21 also includes a connecting pipe 211 disposed at the top of the receiving pipe 215, a transfer pipe 212 disposed between the connecting pipe 211 and the receiving pipe 215, and a connecting groove 213 disposed inside the transfer pipe 212 and having an inverted conical structure. The connecting pipe 211 is used to transport the grouting material brought by the grouting machine body 1.

[0034] Furthermore, refer to Figure 5 and Figure 8 The bottom end of the connecting groove 213 is provided with a connecting port 214, and the diameter of the connecting port 214 is larger than the width of the injection port 234. At the same time, the connecting groove 213 is connected to the injection port 234 through the connecting port 214. The sealant can be output outward through the connection of the three. In addition, the way that the connecting port 214 is larger than the injection port 234 ensures that the injection port 234 is always within the range of the connecting port 214, maintaining the connection between the two.

[0035] Furthermore, refer to Figure 7 The limiting pipe 218 is provided with slots 219 that correspond to the number and position of the transmission rack 233. The slots 219 extend to the outside of the limiting pipe 218. The slots 219 are limited by the limiting pipe 218 and can only move horizontally within the limiting pipe 218.

[0036] Furthermore, refer to Figure 8 and Figure 9 The width of the sealing plate 232 is greater than the width of the nozzle baffle 231, and the two mutually perpendicular sides of the inner side of each set of nozzle baffles 231 respectively abut against the sides of the other two sets of nozzle baffles 231. The sealing plate 232, which is wider than the nozzle baffle 231, can move synchronously in the receiving groove 216 when the nozzle baffle 231 moves. At the same time, it fills the gap caused by the movement with its larger size, thereby blocking the connection between the receiving groove 216 and the injection port 234, thus avoiding leakage.

[0037] Furthermore, refer to Figure 10The driving component 22 also includes a gear ring 221 sleeved on the limiting pipe 218, and the gear ring 221 is rotatably connected to the limiting pipe 218. The gear ring 221 can rotate circumferentially on the connecting groove 213, thereby driving the nozzle component 23 to perform adjustment operations through the helical rack 222.

[0038] Furthermore, refer to Figure 2 A base 11 is provided below the grouting machine body 1. A gear disk 12 is rotatably connected to the base 11, and the gear disk 12 meshes with the drive component 22 for transmission. By meshing with the drive component 22, the gear disk 12 can drive the drive component 22 to rotate, thereby achieving the purpose of adjusting the drive nozzle component 23.

[0039] In summary, the maximum size of an injection port with a diameter of 234 under normal conditions is as follows: Figure 12 As shown, when the output diameter of the nozzle body 2 needs to be adjusted according to requirements, the drive component 22 is driven to rotate. The rotating drive component 22 is driven by the meshing of the helical rack 222 and the transmission rack 233, which pushes the transmission rack 233 to slide horizontally along the slot 219. At this time, the four sets of transmission racks 233 move synchronously, so the four sets of nozzle baffles 231 also move synchronously. At this time, the four sets of transmission racks 233 will move along one side of the rectangular slot 217 respectively, and the movement directions of adjacent sets of transmission racks 233 are perpendicular to each other in an arc. For specific details, please refer to [reference needed]. Figure 12 and Figure 13 As the four sets of nozzle baffles 231 move along with the transmission rack 233, they gradually and proportionally compress the injection orifice diameters 234 among the four, ultimately changing the diameter of the injection orifice diameter 234. Figure 13 As shown, this allows for the modification of the injection nozzle diameter 234, thereby meeting the needs of grouting repair work for cracks of different sizes. This enables the device to flexibly handle various crack conditions, improving its applicability in different construction scenarios and better meeting the needs of various road surface grouting repairs. Furthermore, the device's adjustable output nozzle diameter allows for quick adjustment based on crack width without changing the nozzle, significantly saving construction time and improving efficiency.

[0040] Furthermore, referring to the figure, a rectangular shaft 121 with a rectangular structure is provided above the gear disk 12, and a screw 13 is inserted above the rectangular shaft 121, with the gear disk 12 and the screw 13 mutually limiting each other in the circumferential direction.

[0041] Furthermore, referring to the figure, the upper end of the screw 13 is threadedly connected to the base 11, and the lower end of the screw 13 is fixedly provided with a sleeve 131. The sleeve 131 has a slot inside that matches the rectangular shaft 121. The rectangular shaft 121 and the sleeve 131 are connected by insertion to limit the circumferential direction of the gear disk 12 and the screw 13, so that the two can rotate synchronously. However, they are not limited in the vertical direction. Therefore, the sleeve 131 can move vertically while driving the rectangular shaft 121 to rotate. The screw 13 is threadedly connected to the base 11 and can move vertically on the base 11. Then, through the cooperation of the sleeve 131 and the rectangular shaft 121, the gear disk 12 drives the drive component 22 to rotate. At the same time, the screw 13 threadedly connected to the base 11 can play a self-locking function, thereby preventing the nozzle component 23 from shaking after adjustment.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
