[0002] The road marking cleaning vehicle mainly includes a clean water tank, a return water tank (sewage tank), a high-pressure pump system, a power unit, a vehicle front cleaning device, an independent control system, and oil and water pipes. There are currently two commonly used ways to install these equipment: one is to install it exposed on the floor of a vehicle with a Class II chassis, and the equipment does not have an outer cover on the periphery. The disadvantage is that the whole vehicle is not beautiful, and the equipment is exposed to the open air without protection and dustproof; the other is to install it in a compartment, and the whole vehicle becomes a traditional fully enclosed compartment vehicle with a maintenance door. The equipment is installed on the floor of the compartment. Although rolling shutter doors for daily equipment maintenance, inspection, and operation are arranged on the sides and rear of the compartment, the appearance of the whole vehicle is retained. However, due to the limited internal space of the compartment, once the large internal equipment needs overhaul and maintenance, the equipment must not only be decomposed into small parts, but sometimes the equipment must be completely disassembled before it can be removed, which is labor-intensive, time-consuming, and inefficient.
