Frog self-lubricating coating device and method and frog structure
The embodiment of the invention provides a frog self-lubricating coating device and method and a frog structure, and relates to the field of railway turnouts. The frog self-lubricating coating devicecomprises an oil spraying assembly used for being installed on a frog structure. The oil injection assembly comprises an oil storage tank, an oil pump, an oil injection pipeline and an oil injection nozzle, the oil injection pipeline is connected with the oil storage tank and the oil injection nozzle, the oil pump is connected with the oil injection pipeline and used for enabling lubricant in theoil storage tank to flow along the oil injection pipeline, and the oil injection nozzle is used for injecting lubricant to easily-abraded parts of the frog structure. According to the frog self-lubricating coating device, the frog self-lubricating coating method and the frog structure, the friction coefficient of wheel rail contact can be reduced and controlled within a certain range, so that acting of the wheel rail friction effect in the turnout passing process of a train is reduced, abrasion of easily-damaged parts of the frog is reduced, and the service life of the frog is prolonged. And meanwhile, the maintenance cost is also reduced in an automatic coating mode.
本发明的实施例提供了一种辙叉自润滑涂敷装置、方法和辙叉结构，涉及铁路道岔领域。辙叉自润滑涂敷装置包括用于安装于辙叉结构的喷油组件，喷油组件包括储油罐、油泵、喷油管路和喷油嘴，喷油管路与储油罐和喷油嘴连接，油泵与喷油管路连接，用于使储油罐内的润滑剂沿喷油管路流动，喷油嘴用于向辙叉结构的易磨损部位喷出润滑剂。上述的辙叉自润滑涂敷装置、方法和辙叉结构能够减小轮轨接触的摩擦系数并将该摩擦系数控制在一定范围，从而减少列车过岔过程中轮轨摩擦作用的做功，达到减少辙叉易损部位的磨损，提高辙叉使用寿命。同时，通过自动涂敷的方式也降低了维护成本。
