Description

Technical Field

[0001] This utility model relates to the field of road and bridge construction technology, specifically a novel road and bridge expansion joint repair device. Background Technology

[0002] Expansion joints in roads and bridges are an important structural component, mainly used to absorb and mitigate bridge structural deformation caused by factors such as temperature changes, settlement, and vibration. Over time, expansion joints may experience wear, aging, deformation, or leakage, affecting their normal function and requiring repair.

[0003] When using common expansion joint repair equipment, guide wheels are inserted into the interior of the expansion joint to guide the movement of the equipment, allowing it to move along the expansion joint and repair its interior. However, since different types of expansion joints have different internal spacing, and the guide wheels are mostly in fixed positions, it is not easy for them to fit snugly against the inside of different types of expansion joints. The guide wheels are also prone to shaking inside the expansion joint, affecting the guiding function and reducing the applicability of the repair equipment. Utility Model Content
