[0002] In the mass production of locomotive sprockets and chains, the surfaces of the finished chains and sprockets are often covered with dirt or oil, requiring cleaning to meet subsequent assembly or usage requirements. Currently, the industry mostly uses manual cleaning for such chains and sprockets. When the number of chains and sprockets is small, manual cleaning can maintain a certain level of efficiency. However, in mass production scenarios, manual cleaning not only significantly increases the labor intensity of workers but also leads to higher labor costs. Furthermore, the cleaning efficiency is low and cannot keep up with the pace of mass production. At the same time, the cleanliness of manual cleaning is greatly affected by human factors, making it impossible to guarantee consistent cleaning quality, which is detrimental to the smooth progress of subsequent processing steps.

[0003] Therefore, there is an urgent need to design a locomotive sprocket and chain cleaning device that can achieve automatic cleaning and adapt to batch processing needs, in order to solve the problems existing in the current technology. Utility Model Content

[0033] The following is in conjunction with the appendix Figure 1-7 The present invention provides a more detailed description of an embodiment of a cleaning device for locomotive chains and sprockets.

[0034] A cleaning device for locomotive chains and sprockets, such as Figure 1-3As shown, the system includes a cleaning tank 1, a feeding chain device 2, a spraying device 3, and a drying device 4. The cleaning tank 1 serves as a cleaning area for the chain and sprockets, and is a closed tank on all sides and at the bottom. The feeding chain device 2 drives the chain and sprockets along a preset path. The feeding chain device 2 is located inside the cleaning tank 1 and has a level section and an lifting section. The level section is located inside the cleaning tank 1. The lifting section is inclined upward along the discharge end of the cleaning tank 1 and extends out of the cleaning tank 1. The spraying device 3 provides cleaning water containing cleaning agent to rinse the chain and sprockets. The spraying device 3 is fixed to the top of the cleaning tank 1 and is located above the level section of the feeding chain device 2. The drying device 4 is used to dry the cleaned chain and sprockets. The drying device 4 is arranged parallel to the lifting section of the feeding chain device 2.

[0035] Specifically, the cleaning tank 1, as the core area for cleaning chains and sprockets, adopts a tank structure that is enclosed on all sides and at the bottom to store cleaning water and ensure a safe cleaning environment for chains and sprockets. To achieve stable support and height adjustment of the cleaning tank 1 to adapt to different ground flatness and usage scenarios, a support structure is connected below the cleaning tank 1. The support structure is preferably a square tube spaced along the bottom edge of the cleaning tank 1. The square tube has high strength and good support stability. At the end of the square tube, there is an adjustable support component, specifically a foot cup with a nut. To achieve a stable connection between the foot cup and the square tube, a square plate is welded to the end of the square tube. A threaded hole is opened in the center of the square plate, and the foot cup is threaded into the threaded hole. By rotating the nut on the foot cup, the length of the foot cup extending out of the square plate can be changed, thereby adjusting the overall height of the cleaning tank 1 and effectively eliminating the impact of uneven ground on equipment placement.

[0036] To further enhance its automation, the cleaning equipment also includes an electrical control box 10, which is installed on one side of the cleaning tank 1 and electrically connected to the feeding chain device 2, the spraying device 3, and the multi-stage wastewater filtration device 5. As the control core of the entire equipment, the electrical control box 10 receives feedback signals from each device and outputs control commands through its internal preset control circuitry, enabling the coordinated operation of all components. To reduce wiring length, complexity, and cost, the electrical control box 10 is positioned on one side of the cleaning tank 1. Furthermore, to facilitate operation and maintenance by personnel, the electrical control box 10 is free of obstructions from other auxiliary structures, ensuring ample operating space.

[0037] In this embodiment, as Figure 6As shown, the feeding chain device 2 includes a feeding frame 21, a drive shaft 22 disposed at both ends of the feeding frame 21, a drive chain 23 sleeved on both sides of the drive shaft 22, and a geared motor 24 for driving the drive shaft 22 to rotate. Carrying plates 25 are spaced apart on the drive chain 23, and the two ends of the carrying plates 25 are respectively connected to corresponding links on the drive chain 23. The output end of the geared motor 24 is linked to the drive shaft 22 through chain drive. The drive shaft 22 is driven to rotate by the geared motor 24, so as to synchronously drive the drive chain 23 and the carrying plates 25 to move along a preset path.

[0038] Specifically, after the geared motor 24 starts, its output torque is transmitted to the drive shaft 22 through the chain drive, causing the sprockets at both ends of the drive shaft 22 to rotate synchronously, thereby driving the double drive chain 23 to move along the feeding frame 21. When the drive chain 23 moves, the carrying plate 25 fixed on the chain link moves synchronously with the drive chain 23. When the carrying plate 25 moves to the feeding end of the cleaning tank 1, it receives the chain sprocket from the loading plate 12 and then enters the gentle section in the tank. At this time, the chain sprocket is cleaned under the action of the spray device 3 and the high-pressure air agitation. After cleaning, the carrying plate 25 enters the lifting section with the drive chain 23 and gradually leaves the water surface. During this process, the water on the surface of the chain sprocket drips back into the cleaning tank 1 under the action of gravity. Finally, the carrying plate 25 is transported to the top of the lifting section, and the chain sprocket slides off the carrying plate 25 to the subsequent conveying mechanism under the action of gravity, completing the entire conveying process.

[0039] The material carrier plate 25 features a ribbed structure to prevent the chain and sprocket from slipping off the sides of the plate during transport. Multiple through holes 251 are also provided on the plate to facilitate the flow of cleaning agent, ensuring effective cleaning and reducing resistance during water movement. The feeding chain device 2 follows a pre-defined path, passing through both the inside and outside of the cleaning tank 1. The material carrier plate 25 drives the chain and sprocket into the water within the cleaning tank 1 for cleaning. After cleaning, the material is air-dried and then moved outside the cleaning tank 1, thus achieving an automatic transition from cleaning to air-drying and discharge.

[0040] In this embodiment, as Figures 1 to 3 As shown, the spraying device 3 includes a high-pressure water pipe 31, a water supply pipe 32, and multiple nozzles 33. The high-pressure water pipe 31 extends axially along the length of the cleaning tank 1, and one end of the high-pressure water pipe 31 is connected to a water source. Multiple water supply pipes 32 are arranged in parallel, and the multiple water supply pipes 32 are connected to the high-pressure water pipe 31 at intervals along the width of the cleaning tank 1. A throttling valve 34 for controlling the water flow interruption and flow rate is provided between one end of each water supply pipe 32 and the high-pressure water pipe. Multiple nozzles 33 are arranged at intervals on the water supply pipe 32, and the spraying direction of the nozzles 33 is towards the movement path of the material-carrying component.

[0041] Specifically, an external high-pressure water pump pressurizes the water mixed with cleaning agent and delivers it to the high-pressure water pipe 31. The water flow is then distributed to each water supply pipe 32 through a three-way connector. The operator can control the flow rate of a single water supply pipe 32 by adjusting the throttle valve 34 according to the degree of dirt on the chain and sprockets. For example, the flow rate is increased when the dirt is severe and decreased when the dirt is mild. The water flow is delivered to each nozzle 33 through the water supply pipe 32. Under high pressure, a fan-shaped water stream is sprayed from the nozzle 33, covering the chain and sprockets on the feeding chain device 2. When the chain and sprockets move with the material plate 25 in the flat section, they are continuously washed by the high-pressure water from the nozzle 33 above. The dirt and oil on the surface are peeled off and fall into the bottom of the cleaning tank 1 with the water flow to ensure thorough cleaning.

[0042] In this embodiment, as Figure 6 As shown, the air drying device 4 includes a main air pipe 41, a conveying air pipe 42, and a jet nozzle 43. One end of the main air pipe 41 is connected to a blower, and the other end is connected to the conveying air pipe 42. The conveying air pipes 42 are arranged at equal intervals on the main air pipe 41, and an airflow valve 44 is provided between the conveying air pipes 42 and the main air pipe 41. There are multiple jet nozzles 43, and the air delivery direction of the multiple jet nozzles 43 is towards the lifting section movement path of the feeding chain device 2.

[0043] Specifically, after cleaning, the chain and sprocket are conveyed to the lifting section through the smooth section. Under the action of the air drying device 4, the main air pipe 41 transmits the high-pressure airflow sprayed by the blower to the conveying air pipe 42. The airflow is controlled by the airflow valve 44 and then blown onto the surface of the chain and sprocket through the jet nozzle 43, thereby quickly blowing off the residual moisture and achieving the drying effect.

[0044] In this embodiment, as Figure 7 As shown, a multi-stage wastewater filtration device 5 is provided on one side of the cleaning tank 1 for filtering oil and impurities in the wastewater after cleaning. The multi-stage wastewater filtration device 5 is connected to the sewage discharge port 11 of the cleaning tank 1 through a pipe. The multi-stage wastewater filtration device 5 includes a primary filter box 51 for settling impurities, a secondary filter box 52 for separating oil, and a tertiary filter box 53 for discharging wastewater. The primary filter box 51, the secondary filter box 52, and the tertiary filter box 53 are separated by a partition 54. An oil separation plate 521 is provided in the secondary filter box 52, and a connecting hole 541 is provided on the partition 54 between the secondary filter box 52 and the tertiary filter box 53. A filter screen 542 is provided in the connecting hole 541.

[0045] Specifically, the bottom of the primary filter box 51 is designed with an inclination angle of 15-20° to facilitate the sedimentation and cleaning of impurities. Wastewater flows into the primary filter box 51 through the drain port 11. A guide plate is installed at the end of the drain port 11 to slow down the flow rate of the wastewater, allowing metal scraps and large particles of dirt to settle to the bottom of the box under gravity. A drain valve is installed at the bottom of the primary filter box 51, which can be opened periodically to discharge the settled impurities. The partition 54 between the primary filter box 51 and the secondary filter box 52 is relatively low, allowing wastewater in the primary filter box 51 to overflow into the secondary filter box 52. The oil-sludge separation plate 521 in the secondary filter box 52... Located near the top, after sewage flows into the secondary filter box 52, due to the density difference between oil and water, the oil will float to the surface. When flowing through the multi-layer oil separation plate 521, the oil is intercepted on the surface of the oil separation plate 521 and gradually gathers into an oil film. The collected oil can be discharged periodically by replacing the oil separation plate 521. After being separated by the oil separation plate 521, the sewage enters the tertiary filter box 53 through the connecting hole 541 between the secondary filter box 52 and the tertiary filter box 53. Since the connecting hole 541 is equipped with a filter screen 542, it can further intercept the fine impurities contained in the sewage, while preventing oil from entering the tertiary filter box 53 with the water flow. The tertiary filter box 53 is equipped with an activated carbon filter layer and a PP cotton filter layer, with the two filter materials arranged one above the other. After the sewage flows in through the connecting hole 541 of the secondary filter box 52, it first passes through the PP cotton filter layer to intercept fine impurities, and then passes through the activated carbon filter layer to adsorb residual oil and odors. The bottom of the tertiary filter box 53 is connected to a sewage pipe to discharge the qualified sewage in a unified manner.

[0046] In this embodiment, as Figure 3 , 4 As shown, the cleaning tank 1 is also provided with a sewage discharge port 11, which is used to discharge the sewage after cleaning to the multi-stage sewage filtration device 5, and a valve assembly 7 is provided on the sewage discharge port 11.

[0047] Specifically, the drain port 11 is located at the bottom of the cleaning tank 1, near the multi-stage wastewater filtration device 5. The port is connected by a flange, and a matching valve assembly 7 enables automatic control. The valve assembly 7 is an electric butterfly valve. The valve body of the electric butterfly valve is connected to the drain port 11 via a flange, ensuring a tight connection and good sealing performance. The drive end of the electric butterfly valve is connected to the electrical control box 10. When the liquid level is higher than the preset value, the electrical control box 10 controls the electric butterfly valve to open, increasing the valve plate rotation angle, expanding the flow area, accelerating wastewater discharge, and lowering the liquid level. When the liquid level is lower than the preset value, the electrical control box 10 controls the electric butterfly valve to close, reducing the valve plate rotation angle, narrowing the flow area, reducing wastewater discharge, and causing the liquid level to rise again, thereby achieving automatic and stable control of the liquid level in the cleaning tank 1.

[0048] To achieve automatic control of the liquid level in cleaning tank 1 and ensure stable water level during the cleaning process, a liquid level detection device 6 is also installed on cleaning tank 1, such as... Figure 5 As shown, the liquid level detection device 6 includes a float 62 and a slide bar 63. The slide bar 63 is vertically installed inside the cleaning tank 1. The float 62 is sleeved on the slide bar 63 and can slide up and down along the slide bar 63. The float 62 rises and falls synchronously with the change of liquid level in the cleaning tank 1. The liquid level detection device 6 is electrically connected to the electrical control box 10 and can transmit the liquid level signal to the electrical control box 10. The processor in the electrical control box 10 compares the detected liquid level signal with the preset liquid level value and controls the valve assembly 7 at the drain port 11 of the cleaning tank 1 to operate according to the comparison result.

[0049] In this embodiment, as Figure 1-3 As shown, a belt conveyor 8 is provided at the feed end of the cleaning tank 1. The conveying direction of the belt conveyor 8 is adapted to the feeding direction of the feeding chain device 2. A feeding plate 12 is connected between the belt conveyor 8 and the feeding chain device 2. The feeding plate 12 is fixedly installed on the cleaning tank 1, and the two sides of the feeding plate 12 shrink inward to form a constricted structure.

[0050] Specifically, a mounting bracket for the feeding plate 12 is welded to the top of the feeding end of the cleaning tank 1 to fix the feeding plate 12. The tilt angle of the feeding plate 12 is set to 30-45° to ensure that the chain sprockets conveyed by the belt conveyor 8 can slide smoothly onto the feeding chain device 2. The two sides of the feeding plate 12 shrink inward to form a constriction structure to prevent the chain sprockets from sliding out of the tank.

[0051] In this embodiment, as Figure 1 As shown, perforated plates 9 are provided between the two sides of the feeding chain device 2 and the inner wall of the cleaning tank 1. One end of the perforated plate 9 abuts against the feeding plate 12, and the other end abuts against the lifting section.

[0052] Specifically, the perforated plate 9 can effectively prevent the chain sprocket from sliding off the material plate 25 into the cleaning tank 1 under the rinsing of the spray device 3. At the same time, several perforations are evenly punched on the surface of the perforated plate 9, which allows the wastewater after rinsing to flow out into the cleaning tank 1 and then out through the drain port 11 to the multi-stage wastewater filtration device 5 for filtration before being discharged.

[0053] The working process of the cleaning equipment of this utility model is as follows:

[0054] First, the chain sprockets to be cleaned are placed on the belt conveyor 8 and transported to the loading plate 12 at the front end of the cleaning tank 1. Under the action of gravity, the chain sprockets slide down the inclined surface of the loading plate 12 onto the carrying plate 25 of the feeding chain device 2. Then, the equipment is started by the electrical control box 10, and the reduction motor 24 of the feeding chain device 2 starts, driving the transmission chain 23 and the carrying plate 25 to move forward synchronously to transport the chain sprockets. At the same time, the electrical control box 10 controls the valve components of the spray device 3 to open, and cleaning water containing cleaning agent is sprayed from the nozzle 33 through the water supply pipe 32 to clean the chain sprockets on the carrying plate 25. High-pressure rinsing is performed; finally, after the material carrier plate 25 drives the chain and sprocket to complete the cleaning in the cleaning tank 1, the chain and sprocket move away from the water surface as the feeding chain device 2 moves and is transported to the lifting section. The air drying device 4 located above the lifting section sprays high-pressure airflow through the jet nozzle 43 onto the surface of the chain and sprocket, quickly blowing off the residual water. The residual water flows back to the cleaning tank. The dried chain and sprocket move to the top of the lifting section and continue to be transported to the next process. During the cleaning process, the wastewater generated flows into the multi-stage wastewater filtration device 5 through the sewage outlet 11 of the cleaning tank 1. After filtration, the oil and impurities in the wastewater are removed, and the treated water meets the standards and is discharged uniformly.

[0055] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical chains and sprockets are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
