[0035] It should be noted that the terms "first", "second", etc. in the specification and claims of the invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order and sequence. It should be understood that the data used in this way can be interchanged where appropriate, so as to describe the embodiments of the invention described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to the steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0036] The oiling equipment currently used on the Hong Kong high-speed rail line is the ground-fixed curved rail solid lubrication system (II) designed and invented by the China Academy of Railway Sciences. After a period of use, it was found that the oiling effect was not ideal. First, the failure rate is high, and the oil block feeding device often fails, resulting in the inability to feed according to the original design; second, because the lubricant is solid, it is difficult to use the train wheel flange to "drive" grease for long-distance lubrication; therefore, according to the on-site rail wear detection, the project department added manual oiling work, but the development of manual oiling work increased the labor cost, and the employees bent over for a long time when oiling, which was harmful to the employees' occupational health and had low work efficiency. In view of the above situation, after analysis and research by the project department, it was finally decided to design a manual rail oiling trolley.

[0037] like Figures 1 to 3As shown, this embodiment provides an artificial rail oiling trolley, characterized in that it includes: a running device, a solid oil block box 1 and an oil block pressure device, the running device can move back and forth on the rail along the direction of the rail, the solid oil block box is installed on the running device, the solid oil block box 1 is a tubular structure, one end of the solid oil block box 1 is located on the outside of the rail head surface 12 that needs to be oiled, and the oil block pressure device is arranged in the solid oil block box and can apply a certain pressure to the solid oil block so that the lower end of the solid oil block is close to the oiled surface 12 of the rail head.

[0038] In this embodiment, the solid oil block box 1 is used to install solid oil blocks. Compared with liquid lubrication, it can effectively avoid spraying onto the wheel tread to cause the train to slip and pollute the roadbed, and it can also effectively avoid harm to the occupational health of operators.

[0041] In this embodiment, the solid oil block installed in the solid oil block box 1 is pressurized by the trolley push rod handle 4 and the trolley push rod 3, so as to conveniently control the pressure between the solid oil block and the oiling surface 12 and thus control the oiling effect. At the same time, the operator can walk upright and complete the rail oiling without bending over, which reduces the labor intensity.
