[0052] The rail spike detection device 3 is located in front of the sleeper surface cleaning device 2 along the longitudinal direction of the car body. It is used to detect the position of the rail spike on the sleeper. The rail spike detection device 3 can move laterally and vertically relative to the sleeper surface cleaning device 2.

[0053] The road stud oiling device 4 is located on the rear side of the pillow surface cleaning device 2 along the longitudinal direction of the vehicle body; the road stud oiling device 4 includes a mounting bracket 41 and an oiling assembly, the oiling assembly includes a plurality of oiling nozzles 42 for spraying grease, and the mounting bracket 41 is used to connect to the pillow surface cleaning device 2.

[0054] The grease supply device 5 is located on the frame 1 and is connected to the road stud oiling device 4, and is used to inject grease into the road stud oiling device 4.

[0055] The frame 1 supports the overall structure, and the sleeper surface cleaning device 2 is installed on the frame 1 to clean the sleeper surface. By removing debris (such as dust and gravel) from the sleeper surface, a clean working environment is provided for subsequent operations, which helps improve the accuracy and efficiency of subsequent operations (such as spike inspection and lubrication). The specific structure of the sleeper surface cleaning device 2 can be set according to existing technology, and will not be described in detail here.

[0056] In the longitudinal direction of the train body, a rail spike detection device 3 is installed in front of the sleeper surface cleaning device 2. Here and below, "front" refers to the direction of train travel, and "rear" refers to the direction opposite to the direction of travel. The rail spike detection device 3 is positioned in front of the train travel direction to identify the position of the rail spikes on the sleeper in advance. The rail spike detection device 3 has lateral and vertical adjustment capabilities, thereby improving the accuracy of rail spike positioning, adapting to different track gauges or irregularly installed rail spikes, and ensuring the targeted and effective application of lubrication in subsequent operations.

[0057] The road stud oiling device 4, located behind the pillow surface cleaning device 2, consists of a mounting bracket 41 and an oiling assembly. The mounting bracket 41 extends along the length of the pillow surface cleaning device 2, and the oiling assembly is located on the mounting bracket 41. The oiling assembly includes several oiling nozzles 42 for spraying grease. The mounting bracket 41 ensures effective connection between the entire oiling device and the cleaning device. This automates the oiling process, reduces manual intervention, improves work efficiency, and ensures uniform grease coverage of the road studs, extending their service life.

[0058] The grease supply device 5 is located on the frame 1 and connected to the road spike oiling device 4. It is used to inject grease into the road spike oiling device 4. The grease supply device 5 is responsible for providing the necessary grease resources to the road spike oiling device 4 to ensure the continuity of the oiling operation. It ensures that the oiling device always has a sufficient grease supply, avoids maintenance interruptions due to insufficient grease, and improves the reliability and operating efficiency of the equipment.

[0059] The tamping machine provided in this application embodiment has the following technical advantages compared to the prior art:

[0060] In this application, a spike detection device 3 and a spike oiling device 4 are respectively installed on the front and rear sides of the sleeper surface cleaning device 2. The spike detection device 3 is used to detect the position of the spikes on the sleeper. The spike oiling device 4 includes a mounting bracket 41 and an oiling assembly. The oiling assembly includes several oiling nozzles 42 that spray grease. During the tamping operation of the tamping machine, the spike detection device 3 is installed in front of the sleeper surface cleaning device 2. It can be positioned forward of the cleaning device in the direction of train travel to identify the position of the spikes on the sleeper in advance, and the device has lateral and vertical adjustment capabilities. The spike oiling device 4, installed after the cleaning device, consists of a mounting bracket 41 and an oiling assembly. The oiling assembly has multiple oiling nozzles 42 for spraying grease, realizing an automated oiling process, reducing manual intervention, improving work efficiency, and ensuring that the grease evenly covers the spikes, extending their service life. It improves the accuracy of spike positioning, adapts to different track gauges or irregularly installed spikes, and ensures the targeted and effective nature of subsequent oiling operations.

[0061] In one embodiment, the road stud detection device 3 includes:

[0062] First support 31;

[0063] The lateral movement drive 32 has its fixed end located on the first bracket 31;

[0064] The vertical drive component 33 has a fixed end connected to the telescopic end of the horizontal drive component 32.

[0065] The position sensor 34 is connected to the telescopic end of the vertical drive 33, and the detection end of the position sensor 34 is oriented toward the rail surface.

[0066] The first bracket 31 serves as the basic support structure for the entire rail spike detection device 3. Preferably, it extends laterally along the bolster surface cleaning device 2 to fix the lateral movement drive 32 and support subsequent moving components, ensuring the overall structure is stably and reliably installed on the vehicle body. The first bracket 31 is preferably a welded metal structure with sufficient strength and rigidity. The fixed end of the lateral movement drive 32 is fixed to the first bracket 31 and can move laterally. The lateral movement drive 32 can be configured as a cylinder, hydraulic cylinder, or electric push rod. The lateral movement drive 32 drives the vertical drive 33 and its sensor in the lateral direction to adapt to different track gauges or rail spike position deviations. When the bolster surface cleaning device 2 is loaded laterally to the left or right, to ensure the position sensor 34 remains in the same relative position to the rail spike, the direction of movement of the lateral movement drive 32 is controlled to be opposite to the loading direction of the bolster surface cleaning device 2, achieving the aforementioned technical effect.

[0067] The telescopic end of the lateral drive component 32 is connected to the fixed end of the vertical drive component 33, and the telescopic end of the vertical drive component 33 is connected to the position sensor 34 for retracting and extending the position sensor 34. The fixed end of the vertical drive component 33 is connected to the telescopic end of the lateral drive component 32, and the telescopic end can move up and down in the vertical direction. Similarly, pneumatic, hydraulic, or electric methods can be used to drive the position sensor 34 up and down, enabling it to accurately align with the height of the rail spike, which is particularly suitable for situations where the track surface is uneven or the installation height of the rail spikes is inconsistent. The position sensor 34 can be configured as one or more of the following: a laser displacement sensor, a visual recognition camera (image sensor), an ultrasonic sensor, and a proximity switch, used to detect the presence of the rail spike, determine its specific position, and feed back a signal to the control system.

[0068] In another optional embodiment, the vertical drive member 33 only performs the retraction and extension of the position sensor 34; the road stud detection device 3 also includes a vertical adjustment plate 35 and an adjustment block 36; the top end of the vertical adjustment plate 35 is connected to the fixed end of the vertical drive member 33, and the bottom end of the vertical adjustment plate 35 is provided with a first serrated portion 351; the adjustment block 36 includes a body portion 361 and a second serrated portion 362, the body portion 361 has a vertically penetrating relief groove 3611, the vertical adjustment plate 35 is located in the relief groove 3611, the second serrated portion 362 is disposed facing the relief groove 3611 and engages with the first serrated portion 351; the body portion 361 and the second serrated portion 362 are detachably fixedly connected.

[0069] The top of the vertical adjustment plate 35 is connected to the fixed end of the vertical drive member 33, and the bottom end is provided with a first serrated part 351 for mechanical engagement with the adjustment block 36 below to form an adjustable and stable connection structure; as the basic structure for height adjustment, it provides multiple fixed position points through the serrations on the first serrated part 351. The adjusting block 36 includes a body part 361 and a second serrated part 362. The body part 361 has a vertically penetrating relief groove 3611 inside. The second serrated part 362 is arranged facing the inside of the relief groove 3611 and is used to engage with the first serrated part 351 on the vertical adjusting plate 35. It can be understood that the body part 361 and the second serrated part 362 form a U-shaped relief groove 3611. The vertical adjusting plate 35 is inserted into the relief groove 3611, and the first serrated part 351 and the second serrated part 362 are engaged and locked together. The adjusting block 36 is fixed to the vertical adjusting plate 35 by a locking member. The serrated engagement enables the height fine adjustment function and can be firmly locked after adjustment. This allows the vertical position of the rail spike oiling device 4 to be adjusted according to different track gauges, making it suitable for rail spike oiling of different track gauges and increasing the versatility of the device. The vertical adjustment plate 35 and the adjustment block 36 are detachably fixedly connected by means of screws, pins or other means to realize the vertical adjustment of the adjustment block 36.

[0070] Driven by the vertical drive component 33, the entire adjustment structure can move up and down for retraction and extension. At the same time, through the sawtooth engagement structure between the adjustment block 36 and the vertical adjustment plate 35, the sensor installation position can be finely adjusted manually or semi-automatically. After adjustment, the two are locked together with the fixing component to ensure stable position during the detection process.

[0071] Specifically, the second serrated portion 362 is provided with horizontally oriented mounting holes, and the second serrated portion 362 is connected to the body portion 361 via the mounting holes and threaded fasteners. The mounting holes on the second serrated portion 362 are horizontal (i.e., perpendicular to the vertical adjustment plate 35), providing mounting positions for the threaded fasteners and ensuring that the second serrated portion 362 can be securely fixed to the body portion 361, while facilitating disassembly and maintenance. Preferably, two mounting holes are provided, arranged vertically along the second serrated portion 362, to further improve stability. Threaded fasteners (e.g., bolts or screws) are passed through the mounting holes on the second serrated portion 362 and fixed to the corresponding holes on the body portion 361. The clamping force provided by the threaded fasteners ensures a tight fit between the second serrated portion 362 and the body portion 361, preventing loosening or displacement; this helps maintain the accuracy of the serrated engagement structure and ensures stability during height adjustment.

[0072] In another embodiment, the road spike detection device 3 and the road spike oiling device 4 are respectively set into two sets. The two sets of road spike detection devices 3 are set at both ends of the pillow surface cleaning device 2 in the lateral direction. The two sets of road spike oiling devices 4 are set at both ends of the pillow surface cleaning device 2 in the lateral direction.

[0073] The dual-set spike detection devices 3 are located at both ends of the sleeper surface cleaning device 2. Each set of spike detection devices 3 operates independently and can simultaneously detect spikes on both sides of the sleeper. Similarly, the dual-set spike oiling devices 4 are also located at both ends of the sleeper surface cleaning device 2. Each set of oiling devices 4 is responsible for automatically oiling the spikes on the corresponding side. Due to the dual-set configuration, simultaneous detection and oiling of spikes on both sides of the sleeper can be completed in a single pass, significantly improving operational efficiency; it eliminates the need for multiple back-and-forth vehicle movements to cover the entire track width, saving time and resources.

[0074] In some optional embodiments, the grease supply device 5 includes a grease tank 51, a grease pump 52, a grease filter module 53, and an oil pipeline 54 connected in sequence. The oil pipeline 54 is connected to an oil interface for injecting grease into the coating nozzle 42. The coating nozzle 42 includes an air interface and an oil interface. The air interface is connected to a pneumatic device for providing a high-speed airflow to the coating nozzle 42 to disperse and spray the grease. The grease tank 51 is used to store the grease to be sprayed and is fixed on the frame 1. It can be made of metal or high-strength plastic. The grease pump 52 draws grease from the grease tank 51 and pressurizes and transports it. The grease filter module 53 filters the grease during the transportation process, removing impurities and particles, preventing nozzle clogging, improving coating uniformity, and extending the service life of the equipment. It is understood that the grease tank 51, grease pump 52 and grease filter module 53 are all connected by pipelines. The oil pipeline 54 delivers the filtered grease to the oiling nozzle 42 and is connected to the oil circuit structure of the nozzle through pipe joints or quick-connect fittings. The oil pipeline 54 is such as a corrosion-resistant hose or metal pipe.

[0075] The oiling nozzle 42 includes an air interface and an oil interface. The air interface is connected to an on-board pneumatic device (such as an air compressor) to introduce high-speed compressed air, creating an "air-mist mixing" effect that disperses the grease into fine particles before spraying it out. The oil interface is connected to an oil pipe 54 to receive grease from the grease pump 52.

[0076] The specific working process is as follows: grease is drawn from grease tank 51 by grease pump 52; impurities are removed by grease filter module 53; grease is transported to the oil interface of oiling nozzle 42 through oil pipeline 54; at the same time, compressed air enters the nozzle through air interface; inside the nozzle, high-pressure air mixes with grease, and atomizes the grease and sprays it evenly onto the surface of the road stud using pneumatic power.

[0077] Furthermore, the grease supply device 5 also includes a grease pressure regulating module 55, located between the grease filter module 53 and the oil pipeline 54, for regulating the grease spraying pressure. The grease pressure regulating module 55 regulates the pressure of the filtered grease, and can set or automatically adjust the grease pressure output to the nozzle; for example, a manual pressure regulating valve or an electrically controlled proportional pressure valve can be used in conjunction with the control system to achieve intelligent regulation.

[0078] In another embodiment, a pressure detection device is provided between the grease pump 52 and the grease filter module 53. When the grease pressure reaches the upper limit, the grease pump 52 is controlled to stop working. When the grease pressure reaches the lower limit, the grease pump 52 is controlled to start working. The grease supply is controlled by controlling the start and stop of the grease pump 52, thereby improving the system safety.

[0079] In one optional embodiment, the rail spike oiling device 4 further includes a grease back suction valve located on the oiling nozzle 42, used to back suction and store the grease in the oiling nozzle 42 and oil pipeline 54 after the spraying is completed; after the spraying operation is completed, the grease in the nozzle and oil pipeline 54 is actively drawn back to the storage container (such as the grease bucket 51) or a special recycling device to prevent grease from accumulating at the nozzle and dripping, and to avoid contaminating the track or other components.

[0080] Specifically, each pair of oiling nozzles 42 constitutes a group of oiling nozzles 42. The road stud oiling device 4 includes two groups of oiling nozzles 42, which are respectively located at both ends of the mounting bracket 41 along its length. It also includes two baffles 43, which are spaced apart along the length of the mounting bracket 41 and located between the two groups of oiling nozzles 42.

[0081] The nozzles, which were originally distributed independently, are grouped into groups of two nozzles each; this increases the coverage area of ​​a single spray; enhances the uniformity of spraying; and allows for control of different groups as needed, improving flexibility.

[0082] The entire device comprises two sets of 42 oiling nozzles, which are respectively set at both ends of the mounting bracket 41 along its length to achieve simultaneous spraying of rail spikes on both sides of the sleeper; improving work efficiency; reducing the time spent on repeated equipment movement or adjustment; two baffles 43 are set at intervals along the length of the mounting bracket 41; set between the two sets of oiling nozzles 42; used to prevent grease from interfering with or splashing between adjacent nozzles; and play a role in isolation, directional spraying, and pollution prevention.

[0083] During the operation of the tamping machine, the track spikes enter the oiling area after being cleaned by the sleeper surface cleaning device 2; two sets of oiling nozzles 42 are located at both ends of the mounting bracket 41, which can spray the track spikes on the left and right sides of the sleeper simultaneously; two baffles 43 are set between the nozzle sets to prevent the grease from flying across the air and causing waste or pollution; guide the grease to spray in the designated direction to improve the spraying accuracy.

[0084] Specifically, in each group of 42 oiling nozzles, one nozzle 42 is positioned vertically, while the other is inclined to the vertical. One nozzle 42 has its axis perpendicular to the rail surface, directly facing the top or center of the rail spike, enabling direct spraying of the main body of the spike; this improves the adhesion rate of grease to critical stress areas; and is suitable for lubricating rail spikes in standard locations. The other nozzle 42 has its axis at a certain angle (e.g., 30°–60°) to the vertical, facing the side or edge of the rail spike, covering the base, sides, or areas difficult to cover by vertical spraying; this prevents "blind spots" caused by obstruction or structural limitations; and enhances overall lubrication and rust prevention.

[0085] During the spraying process, the vertical nozzle in a set of nozzles is responsible for concentrated spraying of the center area of ​​the road spike; at the same time, the tilting nozzle is responsible for auxiliary spraying of the sides and roots of the road spike; the synergistic effect of the two allows the grease to cover the surface of the road spike more comprehensively, improving lubrication efficiency and protective performance.

[0086] Although preferred embodiments of this application have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.

[0087] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
