Cable trench temporary bridge convenient to move

The cable trench temporary bridge convenient to move comprises a bridge body and further comprises a mounting component, a rotating component, an adjusting component and a sliding component, the upper portion of the mounting component is fixed to the bottom of the bridge body, and the rotating end of the rotating component is rotationally connected into the mounting component. According to the cable trench temporary bridge convenient to move, when the bridge body is erected above a cable trench body, the relative fixed positions between the adjusting component and the mounting component and between the adjusting component and the rotating component are adjusted, and the sliding component moves circumferentially along the rotating end of the rotating component so that the sliding component and the bottom of the bridge body can be relatively parallel, relatively inclined and relatively perpendicular; when the sliding part is relatively parallel to the bottom of the bridge body, the sliding part makes contact wi
