The height of the reinforcement device can be adjusted by the lifting mechanism to improve practicality.

[0004] However, due to the setting of the second bearing plate and the support box, the bearing capacity of the support box on the second support plate is small, which makes the second bearing plate prone to breakage, small bearing capacity and low strength. At the same time, due to the small number of connecting devices between the second bearing plate and the buffer plate, when the bridge is placed on the buffer plate, the buffer plate and the bridge are prone to shaking, and the overall stability of the device is low, resulting in low safety and low usability of the device.

[0005] Therefore, we propose a bridge strengthening device. Utility Model Content
