Abstract
Description
Technical Field

[0002] Bridges are under the pressure of vehicles for a long time, so the status of bridges needs to be checked regularly to avoid traffic safety problems caused by damage to the bridges. The bottom of the bridge can most intuitively reflect the status of the bridge after damage. However, in order to support the bridge deck, several piers are arranged at the bottom of the bridge, and multiple narrow walls are formed between the piers. The narrow walls are not conducive to the construction of tracks, so a device that can stably walk between the narrow walls is needed to observe the status of the bottom of the bridge. The spacing between the wheels of the existing inspection trolley cannot be adjusted, and inspection cannot be performed between piers with different spacings. It is necessary to produce trolleys with various spacings for piers with different spacings, which increases the inspection cost. Summary of the invention
