Structure for increasing moving length of sanitation vehicle

The utility model relates to the technical field of sanitation vehicles, and discloses a sanitation vehicle moving length increasing structure which comprises a frame, a carriage bottom plate is movably arranged on the upper surface of the frame, fixed pulleys are fixedly connected to the lower surface of the carriage bottom plate, frame girders are slidably connected to the outer surfaces of the fixed pulleys, and limiting guide rails are fixedly connected to the lower surfaces of the frame girders. The end face of the guide wheel is rotationally connected with a guide wheel arm rod, and the lower surface of the compartment bottom plate is rotationally connected with a main supporting arm rod. The electric push rod is started to extend to drive the guide wheel arm rod to do anticlockwise circular motion around the guide wheel, so that the front end of the main supporting arm rod is driven to move, the main supporting arm rod drives the carriage bottom plate to be pushed out, and the carriage bottom plate can
