Description

Technical Field

[0001] The utility model relates to the technical field of bridge crack repair, in particular to a bridge crack repair device. Background Art

[0002] Bridges generally refer to structures built across rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that are built across mountain streams, poor geology, or to meet other transportation needs to make passage more convenient. During the use of bridges, cracks are prone to appear at the bottom of the bridge, causing the bridge to leak.

[0003] Although the existing bridge crack repair device is used by setting a limit plate, a threaded groove and a limit nut, after the roller is used, the staff can unscrew the limit nut through the threaded groove, and then separate the roller and the support frame. The staff only needs to install a new roller and limit it through the limit plate to use it, thereby improving the reuse rate and reducing the cost of using the device. However, in actual use, it is easy for the staff's hands to be stuck with repair materials and glue, causing inconvenience to the staff. At the same time, when idle, the device cannot be erected and needs to be laid flat, which makes it easy for the roller to contaminate other places and the use effect is poor. Therefore, a bridge crack repair device is provided to solve the above problems. Utility Model Content
