Abstract

The invention provides a paving width automatic control system of a paver. The system comprises a PLC program controller, a control output module and a width detection module, wherein the PLC program controller is connected with the control output module and the width detection module through a signal line. The PLC is used for controlling electromagnetic valves of the paving width of the paver in a concentrated way, the internal structure for adjusting width of the paver is simplified, the reliability of width adjustment is improved, different road construction requirements are satisfied, the road paving quality is improved, and the system has the advantages of convenience for installation and debugging.

Description

Technical field [0001] The invention belongs to the field of road work engineering equipment, and particularly relates to an automatic control system for the paving width of a paver. Background technique [0002] The paver is suitable for paving the base and surface layers of various materials, especially for paving asphalt concrete roads, RCC base layer materials, stabilized soil, etc. It is an essential key equipment for building high-grade highways. The screed device is the key device for the work of the paver. The screed width adjustment is the main factor that directly affects the paving efficiency of the entire paver equipment. The system that controls the paving width generally needs to control more hydraulic solenoid valves. The circuit is complicated. Existing hydraulic control systems generally use relays and hard wiring methods to control numerous hydraulic solenoid valves. The required design, installation, wiring, and debugging workload is large, the failure rate i...
