Working process of asphalt concrete paver

The main engine is used to provide the power needed by the paver and support the frame, and to receive, store and transport the asphalt mixture to the spiral paver. The ironing device mainly includes vibration mechanism, vibration mechanism, ironing board, thickness regulator, road arch regulator and heating system. The screed is the basic machine for shaping and ironing paving materials, and it uses its own weight to pre-compact paving materials.

The thickness adjuster is a manual adjusting device, which is used to adjust the vertical elevation angle of the bottom surface of the flat plate to change the thickness of the pavement layer; The road arch adjuster is a spiral adjusting device located in the middle of the screed, which is used to change the lateral inclination of the left and right halves at the bottom of the screed to ensure that the pavement meets the requirements of a given road arch.

The heating system is used to heat the screed bottom plate and related moving parts, so that they will not stick to the asphalt mixture, ensure the smoothness of the road surface, and can be constructed normally even at low temperature; The vibrating mechanism and the vibrating mechanism vibrate and vibrate the paving materials paved by the spiral paver in turn, and then perform preliminary compaction.

Extended data

Paver operators must receive professional training, understand the mechanical performance and structure, master the knowledge of maintenance, and master the performance, operating essentials and safety matters of the machine. Only after being confirmed by relevant departments can they operate alone.

Before starting the engine, you must check whether the engine oil (engine oil, fuel oil, working oil and lubricating oil) is sufficient, whether the belt on the fan is tight, whether there is oil leakage and whether its components are loose. Check whether all kinds of accessories, accessories and tools needed for the day's work are complete. After the engine is started, run at idle speed for at least two minutes, and check whether the indication of each monitoring system is normal.

Someone must direct the unloading truck to accurately unload the materials into the machine hopper. Before paver operation, it is necessary to get in touch with the left and right leveling personnel to ensure that other personnel are not in operation.

When switching from working gear to driving gear, it must be completed with a small throttle after the machine stops completely and all working parts stop working. It is forbidden for operators to operate after drinking. When operating the equipment, you must dress neatly, and do not wear slippers, smoke, eat and other behaviors that hinder safe operation.
