Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 - 5 , the present invention provides a technical solution: a device for cleaning the construction joint surface of concrete, including a mobile base 1. At both ends of the top of the mobile base 1, support frames 2 are symmetrically arranged. Between the two support frames 2, a three-dimensional adjustment frame 3 is arranged. At the output end of the three-dimensional adjustment frame 3, a grinding mechanism 4 is arranged. Above the three-dimensional adjustment frame 3 on the support frame 2, a water spraying assembly 5 is arranged; at the bottom of the mobile base 1, a plurality of universal wheels 101 are arranged, and a braking assembly 102 is arranged on the universal wheels 101; the grinding mechanism 4 includes an auxiliary frame 401. On both sides of the inner wall of the auxiliary frame 401, swing arms 402 rotatably connected are symmetrically arranged. At the end of the swing arm 402 away from the auxiliary frame 401, a grinding roller 403 rotatably connected is arranged. One end of the swing arm 402 away from the grinding roller 403 is rotatably connected to one end of a cylinder 404, and the end of the cylinder 404 away from the swing arm 402 is rotatably connected to the auxiliary frame 401; on one end of the outer wall of the grinding roller 403, a first gear 405 is arranged. On the outer wall of the swing arm 402 outside the first gear 405, a second servo motor 406 is arranged, and on the output shaft of the second servo motor 406, a second gear 407 meshing with the first gear 405 is arranged.

[0031] In one embodiment, the three-dimensional adjustment frame 3 includes an X-axis drive frame 301, a Y-axis drive frame 302, and a Z-axis drive frame 303. The moving part of the X-axis drive frame 301 is fixedly connected to the Y-axis drive frame 302. The moving part of the Y-axis drive frame 302 is fixedly connected to the Z-axis drive frame 303. The moving part of the Z-axis drive frame 303 is fixedly connected to the grinding mechanism 4. The X-axis drive frame 301 in the three-dimensional adjustment frame 3 drives the Y-axis drive frame 302 and the Z-axis drive frame 303 to move in the X-axis direction, thereby realizing the adjustment movement of the grinding mechanism 4 in the X-axis direction. The Y-axis drive frame 302 in the three-dimensional adjustment frame 3 drives the Z-axis drive frame 303 to move in the Y-axis direction, thereby realizing the adjustment movement of the grinding mechanism 4 in the Y-axis direction. The Z-axis drive frame 303 in the three-dimensional adjustment frame 3 drives the grinding mechanism 4 to move in the Z-axis direction, thereby realizing the movement adjustment of the grinding mechanism 4 in three-dimensional directions.

[0032] In one embodiment, the X-axis drive frame 301 includes a support frame 307, a first servo motor 304, a synchronous belt 305, and two synchronous wheels 306. The two synchronous wheels 306 are rotatably arranged at both ends inside the synchronous belt 305. The output shaft of the first servo motor 304 is fixedly connected to one synchronous wheel 306. The first servo motor 304, the synchronous belt 305, and the two synchronous wheels 306 are all arranged inside the support frame 307. The top of the Y-axis drive frame 302 is fixedly connected to the bottom of the synchronous belt 305. The support frame 307 provides overall support for the X-axis drive frame 301. When the X-axis drive frame 301 works, the first servo motor 304 drives one synchronous wheel 306 to rotate. The two synchronous wheels 306 cooperate to drive the synchronous belt 305 to perform a rotary motion. The Y-axis drive frame 302 moves along the X-axis direction along with the bottom of the synchronous belt 305. The operation is convenient and fast. Moreover, the synchronous belt 305 drive method enables the grinding mechanism 4 to have a certain buffering effect in the X-axis direction during the grinding operation, which can effectively prevent the grinding mechanism 4 from still being directly pushed forward when a rigid collision occurs during the grinding operation, and can effectively reduce the damage of the grinding mechanism 4. The top of the Y-axis drive frame 302 is slidably connected to the bottom of the support frame 307. Designing the Y-axis drive frame 302 to be slidably connected to the support frame 307 can effectively ensure the safety and stability of the horizontal movement adjustment of the Y-axis drive frame 302 along the X-axis direction. Both the Y-axis drive frame 302 and the Z-axis drive frame 303 are electric sliding tables, which can effectively ensure the convenience and stability of the adjustment movement of the Y-axis drive frame 302 and the Z-axis drive frame 303. The Z-axis drive frame 303 is fixedly connected to the slide base of the Y-axis drive frame 302. The Y-axis drive frame 302 drives the Z-axis drive frame 303 to move in the Y-axis direction through the slide base. The grinding mechanism 4 is fixedly connected to the slide base of the Z-axis drive frame 303. The Z-axis drive frame 303 drives the grinding mechanism 4 to move in the Z-axis direction through the slide base.

[0033] Working principle of the present invention:

[0034] Referring to the attached drawings of the specification Figures 1 - 5 , the present invention is provided with a moving base 1, a three-dimensional adjusting frame 3, a grinding mechanism 4, a water spraying assembly 5, a swing arm 402, a grinding roller 403 and a cylinder 404. The moving base 1 is used for overall moving support of the cleaning device, facilitating the movement of the cleaning device above the concrete construction joint surface, and then fixing the position of the moving base 1; the support frame 2 is used for overhead support between the moving base 1 and the three-dimensional adjusting frame 3, enabling the three-dimensional adjusting frame 3 to perform normal movement adjustment in three-dimensional space; the three-dimensional adjusting frame 3 is used for performing three-dimensional movement adjustment on the grinding mechanism 4, enabling the grinding mechanism 4 to perform automatic walking movement above the construction joint surface, realizing standardized grinding and cleaning of the concrete construction joint surface, and effectively avoiding the problem of uneven and deviated cleaning paths caused by completely relying on workers to push the cleaner; the grinding mechanism 4 is used for polishing and grinding the construction joint surface, and can effectively grind, polish and repair the defects on the top of the construction joint surface; the water spraying assembly 5 is used for spraying water to reduce dust during the grinding and polishing of the construction joint surface by the grinding mechanism 4, which can effectively prevent the dust generated during grinding and polishing from flying outwards, and at the same time clean the dust and sundries on the construction joint surface, and impact and move the dust and sundries away from the construction joint surface;

[0035] A number of universal wheels 101 with braking components 102 are provided at the bottom of the moving base 1. The universal wheels 101 can ensure that the moving base 1 can be freely moved and adjusted, with convenient and fast operation. The braking component 102 is used for braking and fixing the moving base 1 after the position of the moving base 1 is adjusted appropriately, effectively avoiding the displacement of the moving base 1 during the grinding process;

[0036] The auxiliary frame 401 in the grinding mechanism 4 supports the swing arm 402 and the cylinder 404. The cylinder 404 is used for adjusting the swing angle of the swing arm 402. The swing arm 402 is used for swing support of the grinding roller 403, enabling the grinding roller 403 to swing and adjust along with the swing arm 402. At the same time, the grinding roller 403 can rotate at the end of the swing arm 402, and is used for grinding, polishing and leveling the construction joint surface, effectively repairing the surface defects of the construction joint surface;

[0037] The second servo motor 406 can drive the second gear 407 to rotate. The rotation of the second gear 407 drives the first gear 405 to rotate. The grinding roller 403 rotates along with the first gear 405, and the grinding roller 403 performs grinding and polishing treatment on the construction joint surface;

[0038] During the process of the grinding mechanism 4 grinding and processing the construction joint surface, the adjustable cylinder 404 performs telescopic movement. The cylinder 404 drives one end of the swing arm 402 to swing and adjust, thereby driving the grinding roller 403 located at the other end of the swing arm 402 to swing and adjust. The distance between the grinding roller 403 and the construction joint surface can be finely adjusted, and then the grinding and polishing depth of the construction joint surface can be adjusted. Moreover, the grinding contact angle of the surface defects of the construction joint surface can be adjusted, so as to ensure the grinding, polishing and repair effect of the surface defects of the construction joint surface. The grinding roller 403 is used to perform roller-type grinding and polishing treatment on the construction joint surface. When the grinding roller 403 performs grinding and polishing treatment, the grinding roller 403 travels along the length direction of the construction joint surface, so that the dust after being ground and polished by the grinding roller 403 diffuses along the length direction of the construction joint surface, which can effectively prevent the grinding and polishing dust from diffusing to the outside of the construction joint surface. The dust located at the top of the construction joint surface is cleaned under the water spraying treatment of the water spraying component 102, and the grinding dust can be effectively washed away from the top of the construction joint surface, and the grinding dust is washed down from the top of the concrete, avoiding the grinding dust remaining on the top surface of the concrete.

[0039] Please refer to Figure 1 and Figures 5 - 8 As shown in, the present invention provides a technical solution: a concrete construction joint surface cleaning device. The water spraying component 5 includes a water tank 501 and a liquid storage cylinder 502. The water tank 501 is arranged on the top of the support frame 2. The liquid outlet at the bottom of the water tank 501 is connected to the liquid inlet 504 at the top of the liquid storage cylinder 502 through a water pump and a water delivery pipe 503. A plurality of spray heads 505 are obliquely arranged at the bottom of the outer wall of the liquid storage cylinder 502. The two ends of the liquid storage cylinder 502 are respectively fixedly connected to the two swing arms 402. The liquid storage cylinder 502 is arranged between the grinding roller 403 and the cylinder 404. The water spraying component 5 further includes a turntable 506. One side of the top of the turntable 506 is rotationally connected to the bottom of the water tank 501 through a connecting shaft 509. A first winding cylinder 507 is rotatably arranged on the other side of the bottom of the turntable 506. A second winding cylinder 508 is rotatably arranged on the other side of the bottom of the turntable 506. A first torsion spring is arranged between the outer wall of the first winding cylinder 507 and the turntable 506. A second torsion spring is arranged between the outer wall of the second winding cylinder 508 and the turntable 506. The first winding cylinder 507, the second winding cylinder 508 and the connecting shaft 509 are distributed in an isosceles triangle. Limit disks 510 are respectively arranged at the bottoms of the first winding cylinder 507 and the second winding cylinder 508. The first torsion spring and the second torsion spring are respectively a left-handed torsion spring and a right-handed torsion spring.

[0040] The working principle of the present invention:

[0041] Referring to the attached drawings of the specification Figure 1 and Figures 5 - 8, in the present invention, by providing a water tank 501, a liquid storage cylinder 502, a water delivery pipe 503, a liquid inlet 504 and a nozzle 505, the water tank 501 is used to store water liquid in the water spraying assembly 5, the liquid storage cylinder 502 is used for transfer buffering between the water tank 501 and the nozzle 505, the liquid inlet 504 is used to connect the water delivery pipe 503 to the liquid storage cylinder 502, and the nozzle 505 is used for spraying water on the construction joint surface and for dust reduction by spraying water during grinding processing; during use, a water pump conveys the water liquid inside the water tank 501 to the water delivery pipe 503, the water delivery pipe 503 conveys the water to the liquid storage cylinder 502 through the liquid inlet 504, and the water liquid inside the liquid storage cylinder 502 is sprayed out through the nozzle 505; in addition, the liquid storage cylinder 502 is arranged between two swing arms 402, so that the liquid storage cylinder 502 can move along with the swing of the swing arms 402, thereby realizing the adjustment of the distance and angle between the nozzle 505 and the construction joint surface. Before the grinding roller 403 starts grinding, the grinding roller 403 can be adjusted to swing upward, at this time the liquid storage cylinder 502 swings downward, and then the water pump is turned on, and the nozzle 505 performs pre-spraying treatment on the construction joint surface, which can effectively perform water spraying and cleaning treatment on the construction joint surface before grinding treatment; during the process of the grinding roller 403 grinding the construction joint surface, the nozzle 505 also simultaneously performs water spraying and dust reduction and cleaning treatment on the construction joint surface;

[0042] By providing a turntable 506, a first winding cylinder 507 and a second winding cylinder 508, the turntable 506 rotates at the bottom of the water tank 501 through a connecting shaft 509, and the connecting shaft 509 is eccentrically arranged with the turntable 506, so that the movement range of the turntable 506 during rotation is larger, and the rotational movement range of the water delivery pipe 503 at the bottom of the turntable 506 is larger, thereby ensuring that the water delivery pipe 503 can better adapt to the movement adjustment of the liquid storage cylinder 502 along with the grinding mechanism 4, and avoiding the problem that the interface of the water delivery pipe 503 breaks due to excessive tension during the movement adjustment of the grinding mechanism 4;

[0043] Since the liquid storage cylinder 502 and the nozzle 505 need to move along with the grinding mechanism 4, the water delivery pipe 503 needs to be designed with a sufficient reserved length. At the same time, in order to avoid the adverse impact of the reserved water delivery pipe 503 on the movement of the equipment, the first winding cylinder 507 and the second winding cylinder 508 are designed to wind and support the water delivery pipe 503 at the bottom of the turntable 506. The first winding cylinder 507 is located between the water pump and the second winding cylinder 508. One end of the water delivery pipe 503 is connected to the water outlet of the water pump, and then the water delivery pipe 503 is wound around the surfaces of the first winding cylinder 507 and the second winding cylinder 508 in sequence. Finally, the water delivery pipe 503 is connected to the liquid inlet 504 at the top of the liquid storage cylinder 502. The first torsion spring elastically torsionally supports the first winding cylinder 507, and the second torsion spring elastically torsionally supports the second winding cylinder 508, so that the water delivery pipe 503 wound on the first winding cylinder 507 and the second winding cylinder 508 can be elastically wound and unwound along with the tension received by the water delivery pipe 503, which can effectively ensure the wire management effect of the water delivery pipe 503 and effectively avoid the interference between the movement adjustment of the three-dimensional adjustment frame 3 and the grinding mechanism 4 and the water delivery pipe 503;

[0044] The first torsion spring and the second torsion spring are designed as a left-handed torsion spring and a right-handed torsion spring respectively, so that the elastic torsional movement directions of the first winding cylinder 507 and the second winding cylinder 508 are opposite. When the second winding cylinder 508 unwinds, the first winding cylinder 507 winds; when the second winding cylinder 508 winds, the first winding cylinder 507 unwinds. In actual use, when the water delivery pipe 503 is pulled out under the movement of the grinding mechanism 4, the second winding cylinder 508 rotates and unwinds, and the first winding cylinder 507 rotates and winds. When the second winding cylinder 508 rotates and unwinds, the tension of the end of the water delivery pipe 503 close to the liquid storage cylinder 502 increases and it unwinds and moves towards the liquid storage cylinder 502. The end of the water delivery pipe 503 close to the first winding cylinder 507 also unwinds, and the tension received by the first winding cylinder 507 decreases. The first winding cylinder 507 winds the part of the water delivery pipe 503 unwound from the second winding cylinder 507 under the action of the elastic force of the first torsion spring. When the water delivery pipe 503 relaxes under the movement of the grinding mechanism 4, the tension on the outer wall of the second winding cylinder 508 decreases, and the second torsion spring rebounds to drive the second winding cylinder 508 to wind. The water delivery pipe 503 at the end of the outer wall of the second winding cylinder 508 close to the first winding cylinder 507 also winds. The water delivery pipe 503 between the first winding cylinder 507 and the second winding cylinder 508 is pulled out along the first winding cylinder 507 under the winding action of the second winding cylinder 508, and the first winding cylinder 507 unwinds under the tension of the water delivery pipe 503;

[0045] The first winding cylinder 507 is used to provide a buffer storage and processing area between the second winding cylinder 508 and the water pump, ensuring that the water delivery pipe 503 is in a tensioned state during both the unwinding and rewinding processes of the second winding cylinder 508. This can effectively prevent the water delivery pipe 503 from stacking or being bent at a large angle during the unwinding and rewinding processes of the second winding cylinder 508, thereby ensuring the normal water delivery of the water delivery pipe 503.

[0046] During the movement of the grinding mechanism 4, the water delivery pipe 503 on the liquid storage cylinder 502 will first drive the turntable 506 to rotate. As the turntable 506 rotates along the connecting shaft 509, the connection point between the water delivery pipe 503 and the turntable 506 can swing adaptively with the movement of the grinding mechanism 4, which is used to make a large-range adaptive adjustment of the water delivery pipe 503 along with the grinding mechanism 4. At the same time, during the movement of the grinding mechanism 4, it can drive the water delivery pipe 503 to perform unwinding and rewinding operations on the second winding cylinder 508. The unwinding and rewinding operations of the second winding cylinder 508 are used to make a small-range adaptive adjustment of the water delivery pipe 503, which can effectively ensure the safety and stability of the water delivery pipe 503 during the movement of the grinding mechanism 4 and ensure normal water spraying work.
