Description

Technical Field

[0001] This utility model relates to the technical field of crack repair, specifically a fixing structure for repairing cracks in municipal roads and bridges. Background Technology

[0002] After years of use, the structural performance of bridges gradually deteriorates, and damage occurs in many places. Structural cracks on bridges are caused by external loads, and their distribution and width are related to the external loads. The appearance of such cracks indicates that the structural bearing capacity may be insufficient or there are other serious problems. Active cracks are cracks whose width cannot be stabilized under existing environmental and working conditions, and which easily open and close with changes in the stress, deformation, or ambient temperature and humidity of structural components.

[0003] Existing methods for filling and repairing cracks in roads and bridges are relatively simple and cannot provide targeted, firm pressing to the repaired area. As a result, the repaired crack area is not secure, leading to the formation of secondary cracks in a short period of time. This necessitates repeated repairs, which consumes a lot of manpower and resources and shortens the service life of roads and bridges. Therefore, we propose a fixing structure for repairing cracks in municipal roads and bridges to solve the aforementioned problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Please see Figure 1-4 A fixing structure for repairing cracks in municipal roads and bridges includes a workbench 1. Two cylinders 2 are symmetrically mounted on the bottom of the workbench 1. Connecting blocks 3 are fixedly mounted on the bottom of the two cylinders 2. A rotating shaft 4 is rotatably mounted between the two connecting blocks 3. Multiple rollers 5 are slidably mounted on the rotating shaft 4 via a limiting mechanism. Two partitions 10 are symmetrically fixedly mounted on both ends of the outer wall of the rotating shaft 4. By installing the partitions 10, the rotating shaft 4 is limited during sliding operations. The limiting mechanism includes a fixing column 11, which is fixedly mounted on the outer wall of the rotating shaft 4. A groove is formed on the inner wall of the rotating shaft 4 and slidably connected to the fixing column 11. The fixed column 11 facilitates the limiting operation of the rotating shaft 4 of the sliding operation. It should also be noted that a storage bin 12 is fixedly installed at the top of the workbench 1, and a conveying pipe 13 is connected to the bottom of the storage bin 12. A valve is opened on the conveying pipe 13. The installation of the storage bin 12 and the conveying pipe 13 facilitates the filling operation of the crack. Two upright plates 14 are symmetrically fixedly installed at the bottom of the workbench 1. Multiple wheels 15 are symmetrically rotated and installed at the bottom of each upright plate 14. The installation of the upright plates 14 and the wheels 15 facilitates the movement of the device. A handle 16 is fixedly installed at the top of the workbench 1. The installation of the handle 16 facilitates the movement of the device.

[0025] Please see Figure 1-4 A connecting plate 6 is fixedly installed at the bottom of the workbench 1. Multiple sliding grooves 7 are provided on the connecting plate 6. A limiting plate 9 is fixedly installed at the front end of each sliding groove 7. The limiting plates 9 are slidably engaged on several of the sliding grooves 7. The bottom area of ​​the limiting plates 9 is in contact with the outer wall of the rotating shaft 4. This municipal road and bridge crack repair fixing structure uses rollers 5 to slide on the rotating shaft 4. Different numbers of rollers 5 are arranged for different sizes of cracks. While the limiting plates 9 slide on the sliding grooves 7, they also limit the outer wall of the rollers 5. The cylinder 2 provides power to the connecting block 3, which in turn drives the rotating shaft 4 and rollers 5 to move. The rollers 5 press the cracks, improving the device's targeting for crack repair, enhancing the repair effect, and increasing its practicality.

[0026] In summary, when using this municipal road and bridge crack repair and fixing structure, the storage bin 12 and the delivery pipe 13 work together to fill the cracks. The rollers 5 slide on the rotating shaft 4 under the limitation of the fixed column 11. Different numbers of rollers 5 are arranged for cracks of different sizes. The limiting plate 9 slides and engages with the chute 7 and is fixed under the limitation of the baffle 8. The limiting plate 9 contacts the outer wall of the rollers 5 to limit the rollers 5. The cylinder 2 provides longitudinal force to the connecting block 3, which in turn drives the rotating shaft 4 and the rollers 5 to squeeze the cracks. Thus, targeted repair work can be carried out for cracks of different sizes.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
