The utility model discloses a
wharf trestle device which comprises a base, a first hinge, a large gangplank, a second hinge, a small gangplank, two stand columns and two sets of tensioning structures. The
wharf trestle device is arranged at a
fixed position and is fixed through a connecting channel composed of the small springboard, the large springboard and the base, when the
barge moves due to the influence of sea stormy
waves and tide fluctuation, an
excavator does not need to be frequently used for correcting deviation, and the loading efficiency of the
barge is improved; the large gangplank, the small gangplank and the base are connected through the hinges, mobility is achieved, the connecting channel can change along with rising and falling of the
barge during rising and falling of the tide and can be freely adjusted through the
winch, the stability of the connecting channel is guaranteed, and the
operation safety of the barge is improved; the
laser signal transmitting and receiving module transmits the pulse
laser and records the reflection
time difference to generate the 3D
point cloud model of the
wharf and the barge so as to accurately control the barge berthing range, and connection between the automatic trestle device and the barge is facilitated.
