Description

Technical Field

[0001] This utility model relates to the field of building engineering maintenance technology, and in particular to a concrete crack filler. Background Technology

[0002] In construction engineering, concrete, as a widely used building material, is extensively used in the construction of various building structures due to its high strength, durability, and plasticity. However, due to various factors such as temperature changes, humidity differences, foundation settlement, structural loads, and the shrinkage of the concrete itself, cracks inevitably appear in concrete structures. The presence of concrete cracks not only affects the appearance of the building but can also reduce the load-bearing capacity and durability of the concrete structure. When cracks develop to a certain extent, moisture, air, and various harmful chemicals can penetrate into the concrete, accelerating the corrosion of the reinforcing steel, thereby weakening the bond between the concrete and the steel, and ultimately affecting the safety of the entire building structure.

[0003] In existing technologies, traditional crack repair methods often rely on manual operation of tools for filling, smoothing, and compaction. This is not only inefficient, but also difficult to guarantee the quality of repairs due to the instability of manual operation. For example, when smoothing after manually filling cracks, it is difficult to achieve a smooth and uniform surface, which may lead to uneven distribution of the repair material and affect its bonding with the original concrete structure. During the compaction process, manual operation is unlikely to achieve the desired compaction effect, resulting in insufficient structural strength at the repair site, making it prone to recurrence of cracks, and thus affecting the stability and safety of the entire building structure. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the existing technology involves manual operation of tools for filling, smoothing and compacting, which is not only inefficient, but also makes it difficult to guarantee the quality of repairs due to the instability of manual operation. Therefore, this invention proposes a concrete crack filler.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a concrete crack filler, comprising a base and a material box. A caster wheel is fixedly installed on the lower surface of the base, and a push handle is fixedly installed on the upper surface of the base. A feed pipe is fixedly installed on the surface of the material box, and a discharge pipe is fixedly installed on the lower surface of the material box.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the hydraulic cylinder A can drive the mounting plate A and the scraper plate below it to move up and down. After the concrete repair material is filled, it can be smoothed in time, which can enhance the bonding stability between the repair site and the original concrete structure.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-5 As shown, this utility model provides a technical solution: a concrete crack filler, including a base 1 and a material box 2. A caster wheel 3 is fixedly installed on the lower surface of the base 1, and a push handle 4 is fixedly installed on the upper surface of the base 1. A feed pipe 5 is fixedly installed on the surface of the material box 2, and a discharge pipe 6 is fixedly installed on the lower surface of the material box 2. A motor A7 is fixedly installed on the surface of the material box 2, and a stirring rod 8 is rotatably connected inside the material box 2. A bracket A9 is fixedly installed on the surface of the base 1, and a hydraulic cylinder A10 is fixedly installed on the surface of the bracket A9. An installation plate A11 is slidably connected to the inner side of the bracket A9, and a scraper plate 12 is fixedly installed on the lower surface of the installation plate A11. A side of the installation plate A11 is fixedly connected to... A sliding block A13 is attached. A fixing plate 14 is fixedly installed on the surface of the base 1. A hydraulic cylinder B15 is fixedly installed on the surface of the fixing plate 14. An installation plate B16 is slidably connected to the inner side of the fixing plate 14. A rolling roller 17 is provided on the inner side of the installation plate B16. A sliding block B18 is fixedly connected to the side of the installation plate B16. A sliding rod 19 is fixedly installed inside the fixing plate 14. The output end of the motor A7 is fixedly connected to one end of the stirring rod 8. The output end of the hydraulic cylinder A10 is fixedly connected to the surface of the installation plate A11. The sliding block A13 is slidably connected to the bracket A9. The output end of the hydraulic cylinder B15 is fixedly connected to the side of the sliding block B18. The sliding block B18 is slidably connected to the sliding rod 19.

[0024] In this embodiment, by activating the hydraulic cylinder A10 on the support A9, its output end pushes the mounting plate A11. Since the sliding block A13 is slidably connected to the support A9, the mounting plate A11 can move down smoothly. The scraper plate 12 on the lower surface of the mounting plate A11 moves down accordingly, smoothing the concrete repair material filled in the crack. After smoothing, the hydraulic cylinder B15 on the fixing plate 14 is activated. The output end of the hydraulic cylinder B15 pushes the sliding block B18. Since the sliding block B18 is slidably connected to the sliding rod 19, the mounting plate B16 drives the inner roller 17 to move down, compacting the smoothed repair material, so that the repair material is tightly bonded to the road crack.

[0025] Example 2: Figures 1-5As shown, a bracket B20 is fixedly mounted on the surface of the base 1, a hydraulic cylinder C21 is fixedly mounted on the surface of the bracket B20, a mounting plate C22 is slidably connected to the inner side of the bracket B20, a cleaning brush 23 is rotatably connected to the inner side of the mounting plate C22, a sliding block C24 is fixedly connected to the side of the mounting plate C22, a motor B25 is fixedly mounted to the side of the mounting plate C22, a gear A26 is fixedly mounted to the output end of the motor B25, a gear B27 is fixedly mounted to one end of the cleaning brush 23, the output end of the hydraulic cylinder C21 is fixedly connected to the side of the mounting plate C22, the sliding block C24 is slidably connected to the mounting plate C22, and the gear A26 and the gear B27 mesh and transmit power.

[0026] In this embodiment, before the filling operation, the hydraulic cylinder C21 on the bracket B20 is activated, and its output end pushes the mounting plate C22. The sliding block C24 ensures that the mounting plate C22 slides smoothly. The mounting plate C22 drives the inner cleaning brush 23 to approach the crack. Then, the motor B25 on the side of the mounting plate C22 is activated, and the gear A26 at the output end of the motor B25 rotates. Since the gear A26 meshes with the gear B27 at one end of the cleaning brush 23, the cleaning brush 23 starts to rotate at high speed to clean the crack and remove dust and debris from the crack, preparing for the subsequent filling and bonding of the repair material.

[0027] The working principle of this embodiment is as follows: When in use, first push the handle 4, and use the universal wheels 3 on the lower surface of the base 1 to move the filler to the location of the concrete crack. Then, add the repair material into the material box 2 through the feed pipe 5, start the motor A7 on the surface of the material box 2, and the output end of the motor A7 drives the stirring rod 8 to rotate inside the material box 2 to stir and mix the repair material. After the stirring is completed, the repair material flows to the crack through the discharge pipe 6. After a certain amount of repair material is filled into the crack, the hydraulic cylinder A10 on the bracket A9 is activated, and its output end pushes the mounting plate A11. Due to the sliding connection between the sliding block A13 and the bracket A9, the mounting plate A11 can move smoothly downwards. The scraper plate 12 on the lower surface of the mounting plate A11 moves downwards accordingly, smoothing the concrete repair material filled into the crack. After smoothing, the hydraulic cylinder B15 on the fixed plate 14 is activated, and the output end of the hydraulic cylinder B15 pushes the sliding block B18. Due to the sliding connection between the sliding block B18 and the sliding rod 19, the mounting plate B16 drives the inner roller 17 to move downwards, compacting the smoothed repair material. To ensure a tight bond between the repair material and the road surface cracks, before filling, the hydraulic cylinder C21 on the bracket B20 is activated. Its output end pushes the mounting plate C22, and the sliding block C24 ensures that the mounting plate C22 slides smoothly. The mounting plate C22 drives the inner cleaning brush 23 to approach the crack. Then, the motor B25 on the side of the mounting plate C22 is activated, and the gear A26 at the output end of the motor B25 rotates. Since the gear A26 meshes with the gear B27 at one end of the cleaning brush 23, the cleaning brush 23 begins to rotate at high speed to clean the crack, removing dust and debris from the crack, preparing it for subsequent filling and bonding of the repair material.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
