Rail brake device for track running machine

摘要

Problem to be solved: to provide a rail brake system of a track running type machine capable of remodeling a control device and reducing the cost of wiring and capable of shortening the remodeling period.Fluid pressure cylinders 41 andFluid pressure unit 42Rail clamp opening / closing detector 60 for detecting the operating state of rail clamp to clamp railA traveling brake opening / closing detector 70 for detecting an operating state of a running brake provided in a running drive motor of a track running machine andA running speed detector 80 for detecting the running speed of a track running machine is provided.AndOperating condition of rail clamp detected by rail clamp opening / closing detectorThe running state of the running brake detected by the traveling brake opening / closing detector 70 andA simplified controller 90 is provided for outputting the control signal 90a to the fluid pressure unit 42 based on the running speed detected by the traveling speed detector 80.Diagram
