The swing arm 31 drives the oil separation plate 34 to move with the sliding assembly 2 through the rotating device 32, and the rotating device 32 and the oil separation plate 34 can generate relative rotation. Since the slotted pipe 372 rotates, the oiling pipe 38 that coincides with the axis of the slotted pipe 372 is driven to rotate, and the oiling pipe 38 is connected to the output pipe of the oil separation plate 34. Therefore, the oil separation plate 34 needs to rotate with the slotted pipe 372, and the swing arm 31 connects the vertical guide rod and the oiling assembly 3, so the oil separation plate 34 and the rotating device 32 need to be able to generate relative rotation.

The central oil delivery shaft 320 is a hollow structure, and one end of the central oil delivery shaft 320 is connected to the grease mixing and emulsifying device 4 as an oil delivery pipe, and the other end is hinged to the oil separation plate 34, and is connected to the inner cavity of the oil separation plate 34, so that the oil separation plate 34 and the grease mixing and emulsifying device 4 can produce relative rotation; the middle shell 323 is sleeved on the outside of the central oil delivery shaft 320, and the middle shell 323 is hinged to the swing arm 31, one end of the middle shell 323 is hinged to the outside of the central oil delivery shaft 320 through the cam plate 322, and the other end is fixedly connected to the oil separation plate 34, so that the middle shell 323 can rotate with the oil separation plate 34; the above-mentioned end The rotatable cover 321 is arranged on the outer side of the middle shell 323, and the end cover 321 is fixedly connected to the swing arm 31 to realize the relative rotation of the end cover 321 and the middle shell 323. At the same time, the swing arm 31 can drive the height adjustment of the oiling component 3 through the end cover 321; the above-mentioned sensor 33 is installed on the end cover 321, and when the raised portion of the cam plate 322 contacts the sensor 33, the sensor 33 is triggered to control the sliding component 3 to slide along the vertical guide rod 1. Specifically, the sliding component 2 is realized by starting the control driving device 22.

[0074] The oiling pipe 38 disclosed in the present application includes: a sleeve 381, an oil sealing plate 382, ​​a push rod 384, a spring 383 and an elastic telescopic sleeve 385. Among them, the sleeve 381 is sealed and connected to the output pipe 342 on the shell 341 of the oil distribution plate 34, and the sleeve 381 has a step hole connected to the output pipe 342, and the step hole is divided into a first hole section, a second hole section and a third hole section in the direction away from the oil distribution plate 34, and the diameter of the first hole section and the third hole section is greater than the diameter of the second hole section. The oil sealing plate 382 is arranged at the step surface between the first hole section and the second hole section and can seal the step surface so that the first hole section and the second hole section can be separated by the oil sealing plate 382 to prevent oil leakage. One end of the push rod 384 is fixedly connected to the oil sealing plate 382, ​​and the other end is slidably matched with the side wall of the third hole section through a top plate with an oil through hole, and the top plate is used to abut against the fastener. One end of the spring 383 is arranged between the step surface of the second hole section and the third hole section and the top plate; the elastic expansion sleeve 385 is arranged at the end of the sleeve 381 away from the oil distribution plate 34, and can cover the fastener. The elastic expansion sleeve 385 is made of non-metallic elastic material and installed at the lower part of the sleeve 381. The interior is a hollow structure, the outer wall is composed of folds, and the lower part has an open edge for wrapping the fastener.

[0075] During the oiling operation, after the slotted tube 372 is matched with the fastener, when the oiling assembly is pressed down, the fastener enters the oiling tube 38 through the edging opening of the elastic telescopic sleeve 385, and pushes against the push rod 384, so that the oil sealing plate 382 and the opening of the sleeve 381 are opened, and the pressurized rust-proof medium enters the elastic telescopic sleeve 385; continue to press down to the end of the stroke, the elastic telescopic sleeve 385 contacts the bottom of the fastener to shrink, and the rust-proof medium seeps out from the edging and reaches the root of the fastener; then the oiling assembly is lifted up, the elastic telescopic sleeve 385 is separated from the fastener, and the edging evenly applies the grease to the fastener, thereby completing the oiling operation.

[0076] Specific oiling process:

[0077] 1. The fastener oiling device is lowered to any position, and the friction column 374 contacts the rail head, so that the escape wheel 37 and the rail are kept at a fixed distance in the horizontal direction. At the same time, due to the action of the reset assembly 35, the lower plane of the escape wheel 37 and the fastener plane are kept at a relatively fixed distance in the vertical direction.

[0078] 2. When the engineering vehicle moves forward, due to the action of the friction column 374, the center line of the escape wheel 37 moves horizontally in the direction of movement, and the slotted tube 372 of the escape wheel 37 is stuck in the fastener. After the open lip 373 contacts the fastener, the longitudinal movement is blocked, forcing the escape wheel 37 to rotate around the fastener, driving the oil distributor 54, the middle shell 323, and the cam plate 322 to rotate and trigger the sensor 33.

[0079] 3. The sensor 33 controls the shortening of the driving device 22 through a signal, so that the oil distribution plate 34 is lowered, and the oiling pipe 38 cooperates with the fastener to apply oil. After the escape wheel 37 rotates a certain angle, the driving device 22 is triggered to lift up, and the oiling pipe 38 is separated from the fastener, and the anti-rust medium is evenly applied on the fastener screw.

[0080] 4. Enter the next cycle.

[0081] The escape wheel is used to automatically locate and capture the railway fasteners to achieve rapid positioning; the oil distributor is used to distribute the anti-rust medium to multiple output shafts, and the railway fasteners are oiled alternately on multiple shafts to achieve automation and standardization of railway fastener oiling.

[0082] Compared with traditional manual fastener oiling, the present invention has the characteristics of automatic collection of fastener positions, automatic fastener oiling, and high operating efficiency. It can save a lot of labor resources and greatly reduce the safety risks of railway operations.
