Research And Produce Of Automatic Oiling Sleeper Bolts Machine

During railway maintenance, it is mainly including sleeper bolts oiled, rail washers and sleepers exchanged. Railway workers loose and tighten sleeper bolts using handing electric spanners, oil them by hand when they oil sleeper bolts. The mechanical oiling machine was created by Shenyang Railway Maintenance Department. Both of tightening torque and oiling quantity are controlled by operator. The machine is difficult to operate and only a sample.Large-size and highly automatic integrated machine is widely used on railway sleeper bolts maintenance in developed countries. There are not any small-size railway maintenance machine technology of other countries can be used for our reference. It needs self research and develop. It is an interesting attempt to create automatic sleeper bolts oiling equipment.The frame of the automatic sleeper bolts oiling machine is the whole of making of by weld stainless pipes. It illuminates the design of the power of oiling machine and the transmission by planet reduction device as well as screw holders driven by inertia dynamic force. It accounts the state tightening torque when a small resistance and the shock tightening torque when the high tightening resistance. This is advance structure which compos of two working states during bolts are tightening processes. When tightening resistance is smaller, turn round is motionless, otherwise is shocking tightening. Design accounting is the foundation basis of compose of oiling working efficiency and accurate tightening torque.The design of PLC control system of the automatic sleeper bolts oiling machine is based on automatic control principle. Oiling machine checks sleeper bolts by means of sensor which installed on the front of turn round head and loosing screw distance by photoelectricity coding device, guarantees oil even by means of controlling screw tightening force, PLC control oil quantity precisely.Automatic sleeper bolts oiling machine have been used in maintaining railways which administered by all Railway Maintenance Departments of Shenyang Railway Bureau and achieved good results. Bolts tightening torque is accurate. Intensity of labour is reduced. Production efficiency has been increased. It jet oil uniformly and ecoomize on oil.
