[0002] In the process of infrastructure construction and building repair, the repair of concrete cracks is an important link that affects the durability and safety of the structure. Traditional concrete crack repair methods mainly rely on manual grouting or simple mechanical equipment for construction. These methods usually have certain limitations, such as low efficiency of manual grouting and difficulty in ensuring construction quality. Existing mechanized grouting equipment often has difficulty in achieving accurate and efficient collaborative operation during gap cleaning and grouting, resulting in uneven construction quality.

[0003] At present, most common crack grouting equipment uses fixed spray devices for operation. During the construction process, the equipment often needs to be moved frequently to adjust the position of the spray gun to adapt to the location and direction of different cracks. This method not only increases the workload of construction workers, but also reduces construction efficiency. In addition, if the dust and impurities on the surface of the cracks are not effectively cleaned, it will affect the permeability of the grouting material and reduce the repair effect. However, many existing crack repair equipment is not equipped with an effective cleaning mechanism. Even if some equipment has a cleaning function, most of them are simple brushing structures, which are not cleaned thoroughly and are difficult to meet high-standard construction requirements.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figure 1-Figure 4 As shown, the present invention provides a technical solution: an inorganic material grouting device for repairing concrete cracks, comprising a grouting vehicle 1, on which a mixing barrel 2 is provided, the mixing barrel 2 is connected to a connecting hose 16 through a delivery pipe 15, and the connecting hose 16 is connected to a spray gun 17; a pumping pump 18 is installed on the delivery pipe 15; a dust cleaning mechanism 4 is provided on the grouting vehicle 1, which is used to clean the dust and impurities in the cracks before grouting; and a spray gun adjustment mechanism is provided on the grouting vehicle 1, which is used to adjust the position of the spray gun 17. The device stores and stirs the inorganic grouting material through the mixing barrel 2, and the pumping pump 18 drives the grouting material to be transported along the delivery pipe 15 to the connecting hose 16, and finally sprayed into the concrete crack by the spray gun 17 to achieve crack filling and repair. The dust cleaning mechanism 4 is started before grouting to clean the dust and impurities inside the crack to ensure that the grouting material can fully penetrate and improve the repair quality. The spray gun adjustment mechanism allows the operator to adjust the direction and height of the spray gun 17 according to the crack position and repair requirements to improve the construction accuracy. The equipment integrates a dust cleaning mechanism 4 to ensure crack cleanliness and improve the adhesion and filling effect of the grouting material; the material pump 18 ensures uniform delivery of the grouting material and improves the repair efficiency; the spray gun adjustment mechanism provides flexible construction adjustment capabilities, which is suitable for different crack forms, improves the repair quality and construction convenience. In addition, the overall equipment has a compact structure and strong mobility, and is suitable for a variety of construction scenarios.

[0028] In another embodiment, the mixing barrel 2 can adopt a structure with different volumes or a heating function to adapt to different types of grouting materials. The delivery pipe 15 can be replaced with a wear-resistant pipe to be suitable for high-strength and high-viscosity grouting materials. The dust cleaning mechanism 4 can adopt ultrasonic vibration or high-pressure airflow cleaning to improve the cleaning effect. The spray gun adjustment mechanism can adopt an electric or automatic control system to improve the adjustment accuracy and the level of construction automation. In addition, the grouting vehicle 1 can be equipped with an optional remote control system to adapt to a more complex construction environment.

[0029] The dust cleaning mechanism 4 includes a dust storage box 401 and a mounting plate 402 mounted on the grouting vehicle 1. The outer wall of the mounting plate 402 is mounted with a motor 403. The output end of the motor 403 is connected to a threaded rod 404. The threaded rod 404 is threadedly connected to a connecting block 405. The connecting block 405 is connected to a connecting frame 406. When the dust cleaning mechanism 4 is started, the motor 403 drives the threaded rod 404 to rotate, so that the connecting block 405 threadedly matched with the threaded rod 404 moves along the axial direction of the threaded rod 404, thereby driving the connecting frame 406 to perform linear motion. The connecting frame 406 can be installed with a dust cleaning brush, a high-pressure air nozzle or other dust cleaning device, so that it can clean the surface or inside of the crack according to the set trajectory. The dust storage box 401 is used to collect dust and impurities generated during the cleaning process, prevent secondary pollution, and improve the cleanliness of the construction area. The dust cleaning mechanism adopts a motor-driven threaded rod structure, which can accurately adjust the position of the dust cleaning device to adapt to cracks of different depths and shapes and improve the cleaning effect. The ash storage box 401 effectively collects dust, prevents pollution of the construction area, and improves the grouting quality. The overall structure is compact and highly automated, which reduces manual operations and improves construction efficiency and repair quality.

[0030] In another embodiment, the ash storage box 401 can be designed to be replaceable so as to quickly clean the accumulated ash. The threaded rod 404 can be replaced by a lead screw or a rack drive to improve the transmission accuracy and stability. The motor 1 403 can be replaced by a stepper motor or a hydraulic drive system to meet different construction requirements. The shape and material of the connecting frame 406 can be adjusted, for example, a flexible structure can be used to adapt to complex crack shapes. In addition, the cleaning mechanism 4 can be equipped with an ultrasonic vibration or high-pressure airflow cleaning system to improve the cleaning effect.

[0031] A limit rod 407 is provided on the mounting plate 402 to guide the connecting frame 406 to move along a fixed track to prevent it from deflecting. A brush 410 is fixed to the bottom of the connecting frame 406 for physically cleaning the surface and interior of the crack. The ash storage box 401 is connected to an ash inlet pipe 408, and the ash inlet pipe 408 is connected to a blower 409. The blower 409 generates an airflow to transport the cleaned dust and impurities through the ash inlet pipe 408 to the ash storage box 401 for collection. A drawer 411 is provided below the ash storage box 401 for storing and facilitating the cleaning of the collected dust and impurities. When the cleaning mechanism 4 is started, the motor 403 drives the threaded rod 404 to rotate, so that the connecting block 405 moves along the axial direction of the threaded rod 404, thereby driving the connecting frame 406 and the brush 410 to reciprocate and clean the surface of the crack. The brush 410 can effectively remove floating dust and impurities in the cracks. At the same time, the blower 409 blows high-pressure air into the cracks to further remove tiny dust. The dust enters the ash storage box 401 through the ash inlet pipe 408 for collection. The limit rod 407 ensures the stable movement of the connecting frame 406 to prevent the brush 410 from deflecting or derailing during cleaning. The dust generated during the cleaning process is stored in the drawer 411. The operator can regularly pull out the drawer 411 for cleaning to maintain the continuous working ability of the equipment. The cleaning mechanism can effectively remove dust and impurities in the cracks through the combination of the brush 410 and the blower 409, thereby improving the quality of grouting repair. The limit rod 407 ensures that the connecting frame 406 moves along a fixed track to improve the cleaning accuracy. The ash inlet pipe 408 cooperates with the ash storage box 401 to enable dust to be collected in a centralized manner, thereby reducing secondary pollution at the construction site. The design of the drawer 411 facilitates the cleaning and maintenance of dust, thereby improving the practicality and continuous operation capability of the equipment. The overall cleaning mechanism has a compact structure and a high degree of automation, which reduces manual operation and improves construction efficiency.

[0032] In another embodiment, the limiting rod 407 may adopt a guide rail slide structure to improve the movement stability of the connecting frame 406. The brush 410 may be replaced with a rotating brush head or a high-frequency vibration brush to enhance the cleaning effect. The blower 409 may be replaced with a vacuum cleaner so that the dust is directly sucked into the ash storage box 401 to improve the dust collection efficiency. The ash inlet pipe 408 may be of an adjustable design to adapt to the depth and width of different cracks. The ash storage box 401 may be equipped with an automatic ash discharge system to reduce the frequency of manual cleaning and improve the continuous operation capacity of the equipment. In addition, the drawer 411 may be designed as a sealed structure to prevent dust leakage and improve the cleanliness of the environment.

[0033] In a possible embodiment, the spray gun adjustment mechanism includes a fixed block 5 fixedly mounted on the grouting vehicle 1, a motor 2 6 is mounted on the fixed block 5, the output end of the motor 2 6 is connected to a rotating shaft 7, a gear 1 8 is mounted on the rotating shaft 7, the gear 1 8 is meshed with a gear 2 9, the gear 2 9 drives the inner rod 10 to rotate, the inner rod 10 is fixedly connected to a support frame 11, a positioning column 12 is mounted on the support frame 11, and the inclined plate 13 is connected, a positioning block 14 is fixed on the inclined plate 13, and a spray gun 17 is mounted on the positioning block 14. When the operator adjusts the spray gun angle, the motor 2 6 drives the rotating shaft 7 to rotate, the rotating shaft 7 drives the gear 1 8 to rotate, the gear 1 8 is meshed with the gear 2 9, so that the gear 2 9 rotates synchronously. The rotation of the gear 2 9 drives the inner rod 10 to rotate, and then drives the support frame 11 to adjust the angle, so that the spray gun 17 changes position accordingly to meet the needs of different crack repairs. The matching structure of the positioning column 12 and the inclined plate 13 ensures that the support frame 11 remains stable during the adjustment process, and the positioning block 14 is used to fix the spray gun 17 to ensure that the spray direction is accurate and does not deviate. The spray gun adjustment mechanism adopts a gear transmission method to realize automatic adjustment of the spray gun angle, which improves the flexibility and accuracy of construction. The rotating shaft 7 is driven by the motor 26, so that the spray gun 17 can be smoothly adjusted to the required direction, which is suitable for repairing cracks of different angles and depths, and improves the adaptability of construction. The design of the support frame 11 and the positioning column 12 ensures the stability of the spray gun and avoids uneven spraying due to vibration or error, which affects the quality of grouting. In addition, the structure of the inclined plate 13 and the positioning block 14 provides additional support, enhances the fixing effect of the spray gun, makes the overall operation of the equipment more stable, and the repair effect is better.

[0034] In another embodiment, the gear transmission mechanism can be replaced by a lead screw or a hydraulic drive structure to improve the adjustment accuracy. The motor 26 can adopt a stepping motor to achieve more accurate angle control. The inner rod 10 can adopt a telescopic structure so that the spray gun 17 can be adjusted in height according to different crack depths. The shapes of the inclined plate 13 and the support frame 11 can be adjusted according to actual needs to optimize the support angle of the spray gun. The positioning block 14 can be designed as a detachable structure to facilitate the replacement of different types of spray guns to meet the needs of different materials or construction conditions.

[0035] The drawer 411 is detachably arranged so that it can be easily taken out and reinstalled from under the ash storage box 401. The drawer 411 is fixed under the ash storage box 401 by a slide rail or a buckle structure. The operator can easily pull out the drawer 411 by a handle to dump and clean the collected dust and impurities, and then push it back to its original position to ensure that the equipment continues to work. When the dust cleaning mechanism 4 is running, dust and impurities enter the ash storage box 401 through the ash inlet pipe 408 and are finally deposited in the drawer 411. When the operator needs to clean, he can directly pull out the drawer 411, pour out the dust and impurities therein, and reinstall it under the ash storage box 401 after cleaning. The detachable design makes the cleaning process faster and more efficient, without the need to disassemble the entire ash storage box 401, reducing maintenance time and improving the working efficiency of the equipment. This embodiment makes the process of cleaning dust and impurities more convenient, reduces the difficulty of manual operation, and improves the efficiency of equipment maintenance through the design of the detachable drawer 411. The operator can quickly dump the collected dust without disassembling the entire ash storage box 401, thereby improving the continuity of construction. The structure is simple in design and easy to install, which improves the practicability and operational convenience of the equipment.

[0036] In another embodiment, the drawer 411 may adopt a slide rail locking mechanism to improve stability and prevent accidental falling off. The drawer 411 may also be equipped with a sealing cover to reduce dust spillage and improve the cleanliness of the cleaning process. In addition, the material of the drawer 411 may be a transparent plastic or metal structure to facilitate observation of dust storage and remind operators to clean it in time. For scenarios with high automation requirements, it can be designed as an automatic drawer cleaning system, which automatically pushes the drawer for cleaning through an electric push rod or a pneumatic device to improve the automation level of the equipment.

[0037] The air inlet of the suction fan 409 is connected to the ash storage box 401 through the ash inlet pipe 408, so that during the cleaning process, the suction fan 409 can generate negative pressure, and the dust and impurities cleaned out of the cracks are sucked into the ash storage box 401 through the ash inlet pipe 408 for centralized collection, thereby avoiding dust spillage and improving the cleaning efficiency. When the equipment starts the cleaning function, the brush 410 cleans the surface and interior of the crack, and at the same time, the suction fan 409 works to generate negative pressure suction, and the dust and impurities are sucked into the ash storage box 401 through the ash inlet pipe 408. The ash storage box 401 temporarily stores dust to prevent dust from drifting into the construction environment. After the ash storage box 401 is full, the operator can clean the dust through the drawer 411 to ensure the continuous operation of the equipment. This embodiment realizes an efficient dust collection function through the cooperation of the suction fan 409 and the ash storage box 401. The negative pressure suction provided by the suction fan 409 allows the cleaned dust to be quickly sucked into the dust storage box 401, preventing dust pollution at the construction site and improving the cleanliness of the working environment. The connection design of the dust inlet pipe 408 ensures that the dust conveying path is unobstructed and improves the collection efficiency. In addition, this design reduces the workload of manual dust cleaning and improves the construction efficiency and the degree of automation of the equipment.

[0038] In another embodiment, the suction fan 409 can be controlled by frequency conversion to adjust the suction force according to different construction environments and improve energy efficiency. The ash inlet pipe 408 can be a hose with adjustable length to meet the cleaning needs of different crack positions. The ash storage box 401 can be equipped with a high-efficiency filtering device to further reduce the risk of dust spillage and improve the air purification effect. In addition, the air inlet of the suction fan 409 can be equipped with a multi-stage filtering system to reduce dust particles from entering the fan, thereby improving the service life of the equipment and the convenience of maintenance.

[0039] The threaded rod 404 is axially connected to the motor 1 403, that is, the output shaft of the motor 1 403 is directly coaxially connected to the threaded rod 404, so that the motor 1 403 can directly drive the threaded rod 404 to rotate, thereby driving the connecting block 405 to move along the axial direction of the threaded rod 404 to achieve the advance and retreat adjustment of the dust cleaning mechanism. When the motor 1 403 is started, its output shaft rotates and drives the threaded rod 404 axially connected thereto to rotate synchronously. Since the connecting block 405 is threadedly connected to the threaded rod 404, the rotation of the threaded rod 404 will push the connecting block 405 to move along the thread direction, thereby driving the connecting frame 406 to move in the specified direction. This axial connection method can ensure the high efficiency of power transmission, so that the dust cleaning mechanism can accurately adjust the position to meet the cleaning needs of different cracks. This embodiment reduces additional transmission components through the axial connection between the threaded rod 404 and the motor 1 403, and improves the overall compactness and power transmission efficiency of the mechanism. This design can ensure the smooth rotation of the threaded rod 404, reduce the transmission error, and improve the accuracy of the dust cleaning mechanism, so that it can accurately adjust the cleaning range. In addition, this structure reduces intermediate transmission devices, reduces maintenance costs, and improves equipment reliability and service life.

[0040] In another embodiment, the threaded rod 404 can be a ball screw to reduce friction and improve transmission efficiency. The motor 1 403 can be replaced with a stepper motor to provide higher precision positioning control. If a larger driving force is required, the threaded rod 404 can be replaced by a hydraulic cylinder or a cylinder drive to meet the needs of larger-scale crack cleaning. In addition, the connection between the threaded rod 404 and the motor 1 403 can be a coupling to absorb vibration and improve transmission stability.

[0041] The outlet end of the spray gun 17 is provided with a replaceable nozzle, so that the spray gun 17 can select a suitable nozzle for grouting according to different construction requirements. The replaceable nozzle can be threaded, snap-on or quick-change joint, which is convenient for operators to quickly replace to adapt to the requirements of different crack sizes, depths and construction environments. When repairing concrete cracks, the grouting material is sprayed into the cracks through the spray gun 17. Different cracks have different widths, depths and grouting flow rates, so the grouting effect can be optimized by replacing nozzles with different calibers, shapes or spray modes. For example, narrow slits can use slender nozzles to improve permeability, while wide slits can use diffuser nozzles to ensure uniform filling. In addition, specific nozzles can provide different spray modes such as atomization, direct injection, and diffusion to adapt to different working conditions. This embodiment uses a replaceable nozzle design to make the application range of the spray gun 17 wider and improve the flexibility and accuracy of construction. The replaceable nozzle can adapt to different crack sizes, ensure uniform filling of grouting materials, and improve the repair effect. At the same time, the design reduces the loss cost of the spray gun 17. When the nozzle is worn, it can be replaced separately without replacing the entire spray gun 17, thereby extending the service life of the equipment. In addition, the design of the quick-change structure improves the replacement efficiency, reduces the construction time, and improves the work efficiency.

[0042] In another embodiment, the nozzle can adopt an automatic adjustment structure to automatically adjust the spray angle or flow rate according to the construction requirements. The nozzle material can be selected from wear-resistant ceramics, stainless steel or polymer composite materials to improve durability and adapt to different grouting materials. The nozzle shape can include round, flat, multi-porous diversion, etc. to adapt to different crack repair requirements. In addition, a multifunctional nozzle assembly can be configured to enable it to quickly switch the spray mode and improve the applicability of the equipment.

[0043] The delivery pipe 15 is made of wear-resistant and corrosion-resistant materials to improve its durability and stability in the process of conveying inorganic grouting materials. The delivery pipe 15 can be made of polymer composite materials, wear-resistant rubber, polyurethane coated hose, stainless steel lined fluorine pipe or other wear-resistant and corrosion-resistant materials to adapt to long-term and high-frequency grouting operations and effectively resist the wear and chemical corrosion of the grouting materials on the pipeline. During the grouting operation, the inorganic grouting material enters the delivery pipe 15 from the mixing barrel 2, and is transported to the connecting hose 16 through the pumping pump 18, and then sprayed into the crack by the spray gun 17. Since the inorganic grouting material may contain fine particles, highly alkaline substances or corrosive components, the delivery pipe 15 needs to have good wear resistance and corrosion resistance to ensure that it is not easy to age, crack or clog during long-term use. The use of highly wear-resistant materials can reduce the wear inside the pipeline, improve the stability and delivery efficiency of the grouting, and at the same time, the corrosion-resistant material can prevent chemical erosion and extend the service life of the pipeline. This embodiment uses wear-resistant and corrosion-resistant materials to manufacture the delivery pipe 15, thereby improving the durability of the pipeline and reducing the replacement frequency due to wear or corrosion, thereby reducing maintenance costs. Wear-resistant materials reduce the loss of the inner wall of the pipeline, making the grouting material delivery smoother and improving construction efficiency. Corrosion-resistant materials prevent pipeline aging or blockage caused by chemical reactions, ensuring the continuity and stability of the grouting operation. In addition, this design is suitable for a variety of complex construction environments, improving the applicability and reliability of the equipment.

[0044] In another embodiment, the delivery pipe 15 may adopt a double-layer composite structure, with the inner layer being a wear-resistant material (such as high-density polyethylene HDPE or polyurethane PU) and the outer layer being a corrosion-resistant material (such as polytetrafluoroethylene PTFE or stainless steel) to further enhance its durability. The delivery pipe 15 may also be equipped with a heating or heat preservation function to meet the construction requirements under different ambient temperatures. In addition, the pipeline interface may adopt a quick-release structure to facilitate maintenance and replacement, thereby improving the convenience of construction.

[0045] The bottom of the grouting vehicle 1 is provided with a lockable universal wheel, so that the equipment can be flexibly moved at the construction site and fixed at a designated position when necessary to ensure the stability of the construction. The universal wheel can be made of high-strength polyurethane material, stainless steel bracket structure, and equipped with an independent brake locking device to adapt to the ground conditions of different construction environments, providing good load-bearing capacity and wear resistance. When the equipment is moving, the operator can push or pull the grouting vehicle 1 so that it can freely adjust its position along the construction area to facilitate the repair work in different crack areas. When the equipment moves to the target construction position, the universal wheel can be fixed by a locking device to keep the grouting vehicle 1 stable and prevent the grouting accuracy from being affected by the movement of the equipment during the construction process. In addition, the 360° rotating design of the universal wheel enables the grouting vehicle 1 to flexibly adjust its direction in a narrow space, thereby improving the operability of the equipment. This embodiment provides a lockable universal wheel at the bottom of the grouting vehicle 1, so that the equipment has good maneuverability and can be stably fixed during construction, thereby improving the convenience of operation and the accuracy of construction. The universal wheel is made of highly wear-resistant material to ensure that it is not easily damaged during long-term use, and can adapt to a variety of ground conditions, such as cement, asphalt, gravel, etc., to improve the applicability of the equipment. In addition, the design of the locking device prevents the equipment from moving during construction, improving construction safety and the stability of the grouting effect.

[0046] In another embodiment, the universal wheel can be designed with air pressure lifting, so that the grouting vehicle 1 can lower its center of gravity after being locked, thereby improving the stability of the equipment. The material of the universal wheel can be shockproof rubber to reduce the vibration when the equipment moves and improve the operating comfort. The locking method can adopt electromagnetic braking or foot-operated braking to improve the convenience and safety of locking. In addition, an automatic leveling function can be designed so that the equipment can adapt to uneven ground and improve construction stability and operating efficiency.

[0047] When the staff uses the grouting vehicle 1 to perform the gap grouting operation, first pour the concrete raw materials into the mixing barrel 2, and by starting the extraction pump 18, the concrete will be transported to the connecting hose 16 through the delivery pipe 15, and then the grouting will be sprayed out through the spray gun 17. Before grouting, the gap needs to be cleaned, and at this time, the motor 403 on the outer wall of the mounting plate 402 is started, and the threaded rod 404 is driven to rotate by starting the motor 403, and the connecting block 405 is driven to move left and right, thereby driving the connecting frame 406 to move left and right, and is limited on the limit rod 407. When the connecting frame 406 moves, it will drive the brush 410 at the bottom to clean the gap. During the cleaning, the dust will be adsorbed into the ash inlet pipe 4 by starting the suction fan 409. 08, and transported to the ash storage box 401, thereby falling into the drawer 411. The garbage can be easily cleaned by pulling out the drawer 411. Through the cooperation between them, the gaps in different positions can be quickly cleaned, thereby improving work efficiency. When grouting the gaps in different positions, the motor 26 on the fixed block 5 is started, and the rotating shaft 7 and the gear 18 are driven to rotate under the action of the motor 26. The rotation of the gear 18 will drive the gear 29 and the inner rod 10 to rotate, thereby driving the support frame 11 and the inclined plate 13 to rotate. The rotation of the inclined plate 13 will drive the spray gun 17 on the positioning block 14 to move left and right, thereby realizing the adjustment of the spray gun 17, so that there is no need to frequently move the equipment during grouting, thereby improving work efficiency.
