Description

Technical Field

[0001] This application relates to the technical field of concrete crack repair, and in particular to a concrete crack plugging device. Background Art

[0002] Concrete crack plugging and repair is a technical work for waterproofing and repairing cracks in concrete structures. Concrete structures are widely used in many fields such as construction and hydraulic engineering. However, affected by various factors such as temperature changes, foundation settlement, self-shrinkage of concrete, and external forces, cracks may appear on the surface or inside of the concrete. If these cracks are not treated in time, it will cause water, air, and other corrosive media to invade, which will in turn lead to problems such as steel bar corrosion and reduced durability of concrete, affecting the safety and service life of the structure. Concrete crack plugging and repair is to seal the cracks by using appropriate materials and processes, such as injecting chemical grouting materials such as epoxy resin, applying waterproof sealant, setting waterstops, or using cement mortar for plugging and repairing, to prevent moisture and other harmful substances from entering, and at the same time restore the integrity and waterproof performance of the concrete structure, so as to ensure that the concrete structure can work normally in various environments, extend its service life, and guarantee the quality and safety of the project;

[0003] Chinese Patent with Publication No. "CN219410473U" discloses a concrete pavement crack repair device, which includes a bottom plate, a material pipe, a nozzle, and a knocking head. Rollers and clamping rods are provided at the bottom of the bottom plate. The clamping rod is located behind the roller. The nozzle is installed on the clamping rod and faces downwards. A material box is provided on the bottom plate. One end of the material pipe is connected to the material box and the other end is connected to the nozzle. A pump is provided on the material pipe; a column sleeve is provided below the bottom plate. The column sleeve is located on both sides of the nozzle. The knocking head is movably arranged in the column sleeve. The knocking head made of rubber moves up and down to knock the ground. The utility model can push the device along the concrete crack on the road surface. The nozzle sprays the repair material into the crack. The operation is convenient and labor-saving. The knocking head repeatedly knocks the ground on both sides of the crack, which can promote the repair material to flow fully downward and around the crack to fill the gap, making the crack repair effect better and more effectively repairing the concrete crack on the road surface. It has good prospects for industrial application;

[0004] In the actual application process of the above device, although it has a certain degree of convenience, by deeply analyzing its application details, it is not difficult to find that there are many problems to be solved. In the concrete crack repair operation, the device only injects the repair material into the crack by relying on the nozzle. However, before injecting the repair material, according to the construction specifications and quality requirements, it is necessary to clean the impurities on the outer surface of the road surface crack to a certain extent to ensure the best repair effect. However, the device obviously lacks the corresponding cleaning structure and cannot meet the requirements of this key pre-treatment process;

[0005] In addition, after the injection repair is completed, in order to ensure the flatness and overall quality of the repaired road surface, it is usually necessary to level the slurry filled in the repair. Obviously, the above device does not have this leveling function, seriously affecting the integrity and quality of the repair work;

[0006] Furthermore, in the actual process of repairing road surface cracks, the road surface cracks present irregular shapes and may extend in any direction. The movement of the nozzle of this device completely depends on manually controlling the bottom rollers, which not only consumes manpower and is laborious to operate, but also difficult to accurately control the movement trajectory of the nozzle, unable to efficiently and flexibly adapt to the repair requirements of various irregular cracks, thus significantly reducing the working efficiency of the entire crack repair. At the same time, the cumbersome operation process also makes the overall repair operation extremely inconvenient, seriously restricting the construction progress and quality. Therefore, it is necessary to improve its design. Summary of the Invention

[0019] In summary, the present application includes the following beneficial technical effects:

[0020] 1. The repair mechanism of this device can achieve precise and flexible operation through dual-motor drive. During use, the first motor can be started, which drives the first gear, causing the first tooth ring meshing with it to rotate, and then driving the sliding ring to rotate within the circular track, changing the displacement direction of the adjustment component. Then, the second motor is started, the lead screw rotates to push the movable block to slide, driving the repair and auxiliary components to linearly displace. The discharge valve is opened, and the repair raw material is injected into the gap through the discharge pipe. During the whole process, there is no need to move the base, and only by controlling the motor, the repair component can freely turn within the circular track to adapt to cracks in various directions, greatly improving the repair efficiency and reducing the frequency of equipment movement;

[0021] 2. By setting the repair component, the stable transportation and stirring of the repair material can be ensured. During use, the repair material enters the tank through the top guiding hopper and the feeding pipe. The concrete delivery pump at the bottom of the tank sends the slurry through the hose and the connecting pipe to the transfer tank. The third motor is started to drive the third gear to rotate the second tooth ring, driving the movable steel ring and the fixing plate, enabling the stirring plate, the side stirring frame and the side stirring plates to stir the material. At the same time, the power augers at the bottom and in the middle of the transfer tank assist in stirring to ensure the stable downward delivery of the raw material, which is transported to the crack through the discharge valve and the discharge pipe. The temporary storage and power stirring functions of the transfer tank ensure the stable progress of the repair work;

[0022] 3. By setting the adjustment component and the auxiliary component to work together, the repair quality can be further improved. During use, the second motor drives the displacement of the movable block, driving the transfer tank and the second gears on both sides to move horizontally. Since the second gears are engaged with the racks, they rotate by themselves when moving. The hexagonal slide bar and the hexagonal sleeve are used to link the cross plate to rotate, driving the cleaning brush plate and the scraper. When grouting, the electric push rod lowers the cleaning brush plate to clean the cracks; after grouting, another electric push rod lowers the scraper to level the surface. The hexagonal slide bar and the hexagonal sleeve cooperate to ensure the stable lifting and rotation of the cross plate, enabling the equipment to complete cleaning and leveling during repair without additional operations, improving the repair efficiency and quality.

Detailed implementation mode

[0032] The following will further elaborate on this application in conjunction with the attached Figures 1-8 drawings.

[0033] An embodiment of this application discloses a concrete crack plugging device. As Figures 1-8 shown, it includes a base 1. Support frames 2 are fixedly installed at the four corners of the base 1. Moving wheels 4 are rotatably connected to the bottom of the support frames 2. A repair mechanism 3 is fixedly installed in the middle of the top of the base 1. A supply mechanism 5 is fixedly installed outside the repair mechanism 3 at the top of the base 1. The output end of the supply mechanism 5 is communicated with the input end of the repair mechanism 3;

[0034] The repair mechanism 3 includes an annular track 31 and a driving component 32. A slip ring 33 is movably installed inside the annular track 31. The driving component 32 is fixedly installed on one side of the top of the base 1. The driving component 32 is in transmission connection with the slip ring 33. A regulating component 34 is fixedly installed on the top of the slip ring 33. A repair component 35 is fixedly installed on the top of the regulating component 34. The top of the repair component 35 is communicated with the output end of the supply mechanism 5. An auxiliary component 36 is arranged outside the repair component 35 inside the regulating component 34. Support frames 2 at the four corners of the base 1 and moving wheels 4 rotatably connected to the bottom facilitate the movement of the device to the concrete cracks that need to be plugged. The repair mechanism 3 in the middle of the top of the base 1 is the core part. The driving component 32 is fixed on one side of the top of the base 1. After being started, the driving component 32 transmits power to the slip ring 33, causing it to move inside the annular track 31. The movement of the slip ring 33 drives the regulating component 34 at the top to move. By changing the direction through the regulating component 34, the repair component 35 fixed at the top can be oriented in different directions. At the same time, the supply mechanism 5 located outside the repair mechanism 3 on the top of the base 1 starts to work, conveying the plugging material to the input end of the repair component 35 through the output end. During the repair process, the auxiliary component 36 located outside the repair component 35 inside the regulating component 34 works together, which can assist in cleaning the outer surface of the crack and smoothing the surface after repair, and jointly complete the plugging work of the concrete crack, realizing the effective repair of concrete cracks at different positions and orientations.

[0035] Please refer to Figures 5-8, the auxiliary component 36 includes a connecting arm 361. The connecting arm 361 is fixedly installed on both sides of the movable block 344. An electric push rod 362 is fixedly connected to the outer side of the connecting arm 361. The bottom output end of the electric push rod 362 penetrates through the connecting arm 361 and is fixedly connected to a bottom plate 363. A linkage cleaning group 364 is provided at the bottom of the bottom plate 363. The linkage cleaning group 364 includes a rack 3641, a connecting plate 3642, and a lower rotating shaft 3643. The rack 3641 is fixedly connected to one side of the top of the rail frame 342. The lower rotating shaft 3643 is rotatably connected to the outer end of the bottom plate 363. The connecting plate 3642 is fixedly installed at the upper end of the outer surface of the main body of the telescopic cylinder. The outer end of the connecting plate 3642 is rotatably connected to an upper rotating shaft 3644. The top of the upper rotating shaft 3644 penetrates through the connecting plate 3642 and is fixedly connected to a second gear 3645. The second gear 3645 is meshed with the rack 3641. The top of the lower rotating shaft 3643 is fixedly connected to a hexagonal slide bar 3646. A hexagonal sleeve 3647 is sleeved on the outer surface of the hexagonal slide bar 3646. The bottom of the upper rotating shaft 3644 penetrates through the connecting plate 3642 and is connected to the top of the hexagonal sleeve 3647. The bottom of the lower rotating shaft 3643 is fixedly connected to a cross plate 36410. A cleaning brush plate 3648 is installed at the bottom of one of the cross plates 36410 on both sides of the movable block 344, and a scraping plate 3649 is fixedly connected to the bottom of the cross plate 36410 on the other movable block 344. When the device operates, when the movable block 344 in the repair mechanism 3 is displaced, the connecting arms 361 fixed on both sides of the movable block 344 move accordingly. The electric push rod 362 on the outer side of the connecting arm 361 is started, and its bottom output end pushes the bottom plate 363 to move up and down. The linkage cleaning group 364 at the bottom of the bottom plate 363 starts to function. The rack 3641 fixed on one side of the top of the rail frame 342 cooperates with the linkage cleaning group 364. When the electric push rod 362 makes the bottom plate 363 descend, the second gear 3645 at the top of the upper rotating shaft 3644 meshes with the rack 3641. Since the position of the rack 3641 is fixed, the movement of the movable block 344 drives the upper rotating shaft 3644 and the second gear 3645 to move. Under the meshing action, the second gear 3645 rotates. The bottom of the upper rotating shaft 3644 is connected to the hexagonal sleeve 3647, and the top of the lower rotating shaft 3643 is connected to the hexagonal slide bar 3646 and is sleeved in the hexagonal sleeve 3647. This structure enables the upper rotating shaft 3644 to drive the lower rotating shaft 3643 to rotate synchronously through the linkage of the hexagonal slide bar 3646 and the hexagonal sleeve 3647 when the upper rotating shaft 3644 rotates. The cross plate 36410 fixed to the bottom of the lower rotating shaft 3643 rotates accordingly. If a cleaning brush plate 3648 is installed at the bottom of one of the cross plates 36410 on one side of the movable block 344, during the rotation process, the cleaning brush plate 3648 can clean the periphery of the concrete gap. If a scraping plate 3649 is at the bottom of the cross plate 36410 on the other side, after the grouting is completed, the scraping plate 3649 rotates to level the repaired area, thereby assisting in completing the plugging and repair work of the concrete gap.

[0036] Please refer to Figures 1-5 , the driving assembly 32 includes a first toothed ring 321 and a first motor 322. The first motor 322 is fixedly installed in the middle of one side of the bottom of the base 1. The first toothed ring 321 is fixedly installed on the outer side of the slip ring 33. The output end of the first motor 322 penetrates through the base 1 and is fixedly connected with a first gear 323. The first gear 323 is meshed and connected with the first toothed ring 321. The adjusting assembly 34 includes side arms 341. The side arms 341 are fixedly connected to the middle of both sides of the top of the slip ring 33. A track frame 342 is fixedly installed on the inner side of the side arms 341. A driving member 343 is fixedly connected to one side of the track frame 342. A movable block 344 is slidably connected inside the track frame 342. The repair assembly 35 is installed on the top of the movable block 344 and the bottom output end penetrates through the movable block 344. The auxiliary assembly 36 is arranged on the outer side of the movable block 344. The driving member 343 includes side plates 3431. The side plates 3431 are fixedly installed at the front and rear ends of one side of the track frame 342. A second motor 3432 is fixedly connected to the front end of one side plate 3431. The output end of the second motor 3432 penetrates through the side plate 3431 and is fixedly connected with a lead screw 3433. The lead screw 3433 is rotatably connected between the inner sides of the two side plates 3431. The movable block 344 is threadedly connected with the lead screw 3433. When the concrete crack plugging device works, the driving assembly 32 serves as the starting end of the movement. The first motor 322 fixed in the middle of one side of the bottom of the base 1 starts, and its output end drives the first gear 323 to rotate. Since the first gear 323 is meshed and connected with the first toothed ring 321 fixed on the outer side of the slip ring 33, when the first gear 323 rotates, it drives the first toothed ring 321, and then drives the slip ring 33 to rotate in the annular track 31. The side arms 341 fixed to the middle of both sides of the top of the slip ring 33 rotate accordingly, changing the direction. The track frame 342 fixed to the inner side of the side arms 341 also rotates synchronously, realizing the adjustment of the orientation of the repair assembly 35. When it is necessary to repair the concrete crack, the side plates 3431 fixed at the front and rear ends of one side of the track frame 342 play a supporting role. The second motor 3432 at the front end of one of the side plates 3431 operates, and its output end drives the lead screw 3433 to rotate. The lead screw 3433 is rotatably connected between the inner sides of the two side plates 3431. When the movable block 344 threadedly connected with the lead screw 3433 rotates, under the action of the screw drive, it makes a linear slide along the inside of the track frame 342. The repair assembly 35 installed on the top of the movable block 344 moves with it, and sends the plugging material conveyed by the supply mechanism 5 to the concrete crack through the bottom output end for repair. At the same time, the auxiliary assembly 36 arranged on the outer side of the movable block 344, such as during the movement, can use the linkage cleaning group 364 to clean the periphery of the crack or level the surface after repair, assisting in completing the entire concrete crack plugging work.

[0037] Please refer to Figures 1-3, the supply mechanism 5 includes a concave frame 51 which is fixedly installed on the top of the base 1 and located outside the annular rail 31.

The output end of the concrete delivery pump 54 is fixedly connected with a hose 55. A connecting pipe 56 is provided at the end of the hose 55. The connecting pipe 56 is rotatably connected to the top of the repair assembly 35 and its bottom is communicated with the inside of the repair assembly 35. A feeding pipe 57 is fixedly connected to the middle of the top of the tank body 53. A guiding hopper 58 is fixedly connected to the top of the feeding pipe 57. A concave handrail frame 6 is fixedly installed on one side of the top of the base 1. An anti-slip handrail cover is fixedly connected to the outer surface of the outer end of the concave handrail frame 6. The concave frame 51 fixed on the top of the base 1 and outside the annular rail 31 stably supports the entire supply mechanism 5. The tank body 53 for storing the leak stoppage material is fixed on the base plate 52 in the middle of the top of the concave frame 51. Before the leak stoppage operation, the leak stoppage material is poured into the guiding hopper 58 at the top and steadily enters the inside of the tank body 53 through the feeding pipe 57. When the concrete gap needs to be repaired, the concrete delivery pump 54 installed at the bottom of the tank body 53 is started. The concrete delivery pump 54 sucks the leak stoppage material inside the tank body 53 and uses the pressure of the pump to push it to the output end and convey it out through the hose 55 fixedly connected thereto. The connecting pipe 56 at the end of the hose 55 is rotatably connected to the top of the repair assembly 35 and its bottom is communicated with the inside of the repair assembly 35, so that the leak stoppage material can smoothly flow into the repair assembly 35 and provide sufficient material support for the repair work. In addition, the concave handrail frame 6 on one side of the top of the base 1 facilitates the operator to push the device to move. The anti-slip handrail cover on the outer surface of the outer end can effectively increase the friction force, facilitating the operator to stably grip and ensuring the safety and convenience of the device during the moving process.

[0038] Please refer to Figures 4-7, the repair component 35 includes a transfer tank 351. The transfer tank 351 is fixedly connected to the top of the movable block 344.

On the top of the base frame 358, there is a fixedly connected third motor 359. The output end of the third motor 359 penetrates through the base frame 358 and is fixedly connected with a third gear 3510. The third gear 3510 is meshed and connected with the second gear ring 356. The connecting pipe 56 is rotatably connected inside the second gear ring 356. The bottom of the connecting pipe 56 penetrates through the top cover 354. The stirring component 357 includes a fixing plate 3571. The fixing plates 3571 are arranged at equal intervals in a ring shape and fixedly connected to the bottom of the movable steel ring 355. The bottom of the fixing plate 3571 is fixedly connected with a side stirring frame 3572. Inside the side stirring frame 3572, there are fixedly connected side stirring plates 3573 at equal intervals. In the middle of the inner side of the side stirring plates 3573 inside the side stirring frame 3572, there is a fixedly connected power auger 3574. The power auger 3574 is rotatably connected to the middle part inside the transfer tank 351. During the process of plugging concrete cracks, the repair component 35 plays a key role in stirring and transporting the plugging material. When the movable block 344 moves to the designated position driven by the adjusting component 34, the transfer tank 351 fixed to the top of the movable block 344 also reaches the corresponding position. The connecting pipe 56 transports the plugging material supplied by the supply mechanism 5 through the rotatable second gear ring 356 and penetrates through the top cover 354 into the transfer tank 351. At this time, start the third motor 359 on the top of the base frame 358. Its output end drives the third gear 3510 to rotate. Since the third gear 3510 is meshed with the second gear ring 356 fixed to the top of the movable steel ring 355, the third gear 3510 rotates to drive the second gear ring 356, and then drives the movable steel ring 355 to rotate. The fixing plates 3571 arranged in a ring shape at the bottom of the movable steel ring 355 rotate accordingly. The side stirring frames 3572, side stirring plates 3573 and the power auger 3574 in the middle of the inner side connected to the bottom of the fixing plate 3571 operate together. The side stirring plates 3573 and the power auger 3574 fully stir the plugging material in the transfer tank 351 to make it evenly mixed. After the stirring is completed, open the discharge valve 352 connected to the bottom output end of the transfer tank 351 penetrating through the movable block 344. The plugging material is transported through the discharge pipe 353 to the concrete crack to complete the repair and filling operation of the crack.

[0039] The implementation principle of a concrete crack plugging device in an embodiment of the present application is as follows: The device is provided with a repair mechanism 3, which greatly improves the flexibility and efficiency of concrete crack repair. During use, the first motor 322 is started, and the power generated by the operation of the first motor 322 drives the first gear 323 to rotate. Since the first gear 323 meshes with the first toothed ring 321, the rotation of the first gear 323 causes the first toothed ring 321 to rotate accordingly. The rotation of the first toothed ring 321 further drives the slip ring 33 to perform circular motion inside the annular track 31. During the rotation of the slip ring 33, the adjustment assembly 34 rotates accordingly, thereby changing the linear displacement direction of the adjustment assembly 34;

[0040] After the displacement direction is adjusted, the second motor 3432 is started. The second motor 3432 drives the lead screw 3433 to rotate. The rotation of the lead screw 3433 converts the threaded motion into the linear sliding of the movable block 344. The sliding of the movable block 344 drives the repair assembly 35 and the auxiliary assembly 36 to perform linear displacement. At this time, the discharge valve 352 is opened, and the repair raw material can be accurately sprayed into the concrete crack through the discharge pipe 353. During the entire repair process, there is no need to move the entire base 1. Only by driving the slip ring 33 to rotate through the first motor 322 to change the displacement direction of the movable block 344 on the rail frame 342, and then using the second motor 3432 to drive the lead screw 3433 to drive the movable block 344 to slide and displace, it can be ensured that the repair assembly 35 can move flexibly in any direction inside the annular track 31 of the base 1, best adapting to the cracks that may extend in any direction, realizing rapid repair operations, avoiding frequent movement of the entire equipment, and effectively improving the crack repair efficiency;

[0041] The setting of the repair assembly 35 provides a strong guarantee for the stable repair of the device. During the repair process, the repair material is guided through the guiding hopper 58 and the feeding pipe 57 at the top and smoothly added into the interior of the tank body 53. A concrete delivery pump 54 is installed at the bottom of the tank body 53. After starting, the concrete delivery pump 54 transports the concrete slurry through the cooperation of the hose 55 and the connecting pipe 56 to the interior of the transfer tank 351;

[0042] Inside the transfer tank 351, the third motor 359 is started. The third motor 359 drives the third gear 3510 to rotate. Since the third gear 3510 is meshed and connected with the second toothed ring 356, the rotation of the third gear 3510 drives the second toothed ring 356 to rotate, thereby driving the movable steel ring 355 to rotate. The rotation of the movable steel ring 355 drives the fixed plate 3571 at the bottom of the top cover 354 to rotate. When the fixed plate 3571 rotates, the stirring plate rotates accordingly, and at the same time drives the stirring side frame and the side stirring plate 3573 to rotate together, playing a good stirring role for the repair material in the transfer tank 351;

[0043] During the stirring process, the power augers 3574 at the bottom and middle of the transfer tank 351 rotate synchronously to assist in stirring the raw materials in the tank, prompting the raw materials to be stably conveyed downward. Eventually, the slurry is stably conveyed through the discharge valve 352 and the discharge pipe 353 into the cracks to be repaired, ensuring the smooth progress of the repair work. The transfer tank 351 can temporarily store the slurry, and the operation of the internal power auger 3574 ensures that the slurry can be stably conveyed into the concrete gaps, realizing the stable gap repair function; the adjustment component 34 and the auxiliary component 36 cooperate with each other, significantly improving the repair efficiency and quality of the device. When the second motor 3432 operates to drive the movable block 344 to linearly displace, the movable block 344 drives the transfer tank 351 to laterally displace. The movement of the movable block 344 simultaneously drives the second gears 3645 on both sides to laterally displace. Since the second gears 3645 are meshed with the racks 3641, during the lateral displacement of the second gears 3645, the racks 3641 drive them to rotate, causing the second gears 3645 to rotate while laterally moving themselves;

[0044] The rotation of the second gears 3645 drives the cross plates 36410 at their bottoms to rotate synchronously through the linkage of the hexagonal slide bars 3646 and the hexagonal sleeves 3647. When performing the grouting operation, start the electric push rod 362 on the cleaning brush plate 3648. The electric push rod 362 operates to drive the bottom plate 363 to drive the cross plate 36410 at the bottom of the rotating shaft to move downward, making the cleaning brush plate 3648 contact the ground, cleaning and brushing the ground cracks to remove impurities, providing a good foundation for subsequent grouting; after the grouting is completed, start another electric push rod 362 to push the scraper 3649 downward, making the scraper 3649 fit the ground. As the rack 3641 drives the second gear 3645 to drive the upper rotating shaft 3644 and the lower rotating shaft 3643 to rotate, it drives the scraper 3649 at its bottom to rotate and fit the repaired area, performing a rotating smoothing operation on the repaired area to ensure the flatness after repair. During the adjustment of the electric push rod 362, the hexagonal slide bars 3646 and the hexagonal sleeves 3647 are stably sleeved and slid with each other, ensuring that the cross plate 36410 can move up and down stably while stably driving its rotation. Through this collaborative design, the device can perform cleaning and smoothing work simultaneously during the repair process without additional operations, effectively improving the overall repair efficiency and repair quality.

[0045] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
