Description

Technical Field

[0001] The utility model belongs to the field of spraying, and particularly relates to a portable rail lubrication spraying device. Background Art

[0002] With the rapid development of the railway transportation industry, the improvement of train operation speed and the increase in traffic volume, the friction problem between wheels and rails has gradually become one of the key factors affecting railway safety and economy. In the traditional railway system, the dry friction between the wheel flange and the rail not only causes serious wear on the rail side, but also may cause problems such as noise and vibration, thus affecting the train operation performance and passenger comfort. To improve this situation, the method of using lubricating oil (grease) as an anti-friction material to reduce the friction between wheels and rails has been widely applied. However, some significant problems have emerged in the actual application of the existing methods.

[0003] When traditional lubricating oil (grease) faces the high-strength impact load borne by the contact surface between the wheel flange and the rail side when a high-speed train passes through a curve, its extreme pressure performance is often insufficient. This results in a very limited lubrication effect even when lubricating oil (grease) is applied, and it is unable to effectively reduce wear. Especially under high-load conditions, the lubricant is easily extruded out of the contact surface and loses its due protective effect.

[0004] Due to its strong fluidity, the liquid lubricating medium is difficult to stably adhere to the side of the rail for a long time. Especially when the train passes by, due to the high-speed rotation of the wheels, the lubricating medium is easily thrown off the track surface, causing the formed instantaneous liquid lubrication layer to quickly disappear and unable to provide continuous and effective lubrication. In this case, the wheel-rail interface is still mainly in a dry friction state and fails to achieve the expected anti-friction effect.

[0005] More seriously, the lubricating oil may penetrate into the micro fatigue cracks on the rail surface to form a so-called "oil wedge". This phenomenon not only weakens the integrity of the rail structure, but also accelerates the crack propagation, leading to the early failure of the rail and shortening its service life. In addition, the existence of the "oil wedge" may also change the contact mechanical behavior between the wheel and the rail, increasing the risk of derailment and posing a threat to railway operation safety.

[0006] Based on this, the utility model proposes a portable rail lubrication spraying device. Summary of the Utility Model

Especially under high-load conditions such as the wheel-rail contact surface of high-speed trains, it can effectively avoid the problem that lubricating oil (grease) is easily extruded or thrown off in traditional lubrication methods.

[0026] Ensure the quality of the lubricating medium: The heating device equipped inside the storage tank can perform appropriate heating treatment on the lubricating medium, which helps to improve the fluidity of the lubricating medium and ensure that it can still maintain good lubrication performance under harsh environments such as low temperatures, so as to better adapt to different working environments.

[0027] Precisely control the spraying position: The walking mechanism composed of walking wheels, walking supports and positioning rollers can achieve precise control of the spraying position, ensuring that the lubricating medium can evenly cover the target area, reducing waste and enhancing the lubrication effect at the same time.

[0028] Enhance the stability and safety of the equipment: The walking mechanism is reasonably designed.

[0029] Facilitate operation and maintenance: The device adopts a modular design concept, such as the adjustable connection method between the storage tank and the walking support, and the detachable fixing structure between the walking positioning support rod and the second track, which greatly simplifies the operation process of the equipment and facilitates daily inspection and maintenance work.

[0030] Energy conservation and environmental protection: By effectively combining the monitoring of the air supply system with the air pump switch, the spraying volume can be intelligently adjusted according to actual needs, avoiding waste of resources caused by excessive use of lubricating media and reducing environmental pollution at the same time.

[0031] Significantly improve the anti-wear effect: Compared with traditional methods, after spraying operations using this portable rail lubrication coating machine, the anti-wear effect of the rail can be increased by approximately 50%.

[0038] The following further elaborates on this application in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant utility model and are not intended to limit the utility model. Additionally, it should be noted that for the sake of description, only parts related to the relevant utility model are shown in the drawings.

[0039] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will detail this application with reference to the drawings and embodiments.

[0040] As Figure 1 - Figure 2 shown, refer to Figure 1 , the present utility model provides a portable rail lubrication spraying device, which includes a storage tank 1, a traveling mechanism 2 and a spraying mechanism 3;

[0041] The storage tank 1 is installed on the traveling mechanism 2. The storage tank 1 is used to store the lubricating medium, and a heating device is installed in the storage tank 1 for heating the lubricating medium;

[0042] A spraying mechanism 3 is installed at the discharge port of the storage tank 1, and the spraying mechanism 3 is used to spray the heated liquid lubricating medium onto the first track 4 to be sprayed;

[0043] The traveling mechanism 2 is arranged on both sides of the first track 4 to be lubricated and moves along the length direction of the first track 4.

[0044] As a further explanation of the present utility model, refer to Figure 1 and Figure 2 , the traveling mechanism 2 includes traveling wheels 21, a traveling bracket 22 and positioning rollers 23;

[0045] The traveling wheels 21 are distributed on the ground on both sides of the first track 4 to be lubricated. The traveling wheels 21 are mounted on the traveling bracket 22, and a storage tank 1 is installed on the traveling bracket 22. Positioning rollers 23 are mounted on the storage tank 1, and the positioning rollers 23 are in rolling contact with the first track 4.

[0046] Preparation before startup: First, place the device near the first track 4 that needs to be lubricated. Ensure that the traveling wheels 21 are correctly placed on the ground on both sides of the track, and the positioning rollers 23 should be in good contact with the track surface to ensure that the device can move smoothly along the track.

[0047] Heating the lubricating medium: Turn on the heating device in the storage tank 1 to preheat the lubricating medium stored therein. This process is to reduce the viscosity of the lubricant so that it can be more easily sprayed evenly onto the track surface through the spraying mechanism 3, and at the same time improve the lubrication effect.

[0048] Start the traveling mechanism: When the lubricating medium reaches the appropriate working temperature, start the traveling mechanism 2. The traveling wheels 21 start to rotate, driving the entire device to move forward along the track direction. During this process, the positioning rollers 23 continuously keep in contact with the track surface to ensure that the device moves stably along the predetermined path.

[0049] Spray lubricating medium: As the device advances, the spraying mechanism 3 extracts the heated lubricating medium from the storage tank 1 and evenly sprays it onto the track surface. The design of the spraying mechanism should consider factors such as the spraying range and injection pressure to ensure that the lubricating medium can effectively cover the entire track surface, especially in the worn areas or key parts of the track.

[0050] Suppose it is necessary to lubricate a 1000-meter-long railway track. The operator first checks and confirms that all components of the device are in good working condition, especially whether the running wheels 21 and positioning rollers 23 can operate normally, whether there is enough lubricating medium in the storage tank 1, and whether the heating device can work properly. Then, place the device at the starting point of the track, adjust the position to ensure that the relative positions of the running wheels 21 and positioning rollers 23 and the track are accurate.

[0051] Next, the operator starts the heating device and waits for a certain time until the lubricating medium reaches the appropriate temperature. Subsequently, start the walking mechanism 2 to let the device automatically travel along the track, and at the same time turn on the spraying mechanism 3 to start the spraying operation. During the whole process, the operator needs to monitor the running state of the device. In case of obstacles or abnormal situations, the equipment should be stopped in time, and after troubleshooting, continue the operation.

[0052] After completing the lubrication of the 1000-meter track, the operator turns off all power supplies and moves the device to a safe place for storage. If necessary, the device can also be cleaned and maintained for future use.

[0053] As a further explanation of the present utility model, a new case Figure 1 On the walking support 22, a storage tank 1 is installed, and its structure is:

[0054] A first guide groove is provided on the walking support 22, and a nut 25 moving along it is arranged in the first guide groove. The nut 25 is threadedly connected with a bolt 26. The bolt 26 is borne on the walking support 22, and the nut 25 is rotatably connected with the storage tank 1.

[0055] When it is necessary to adjust the position of the storage tank 1 in the present utility model, the operator can achieve it by rotating the bolt 26. Rotating the bolt 26 clockwise or counterclockwise will cause the nut 25 threadedly connected with it to move forward or backward in the first guide groove.

[0056] Since the storage tank 1 is rotatably connected with the nut 25, as the nut 25 moves, the storage tank 1 will also adjust its position accordingly, so that the height or front-back position of the storage tank 1 can be finely adjusted to adapt to tracks of different heights or widths.

[0057] Since the spraying mechanism 3 sprays on the side of the first track 4, by rotatably connecting the nut 25 to the storage tank 1, the spraying mechanism 3 can be swung to the side of the first track 4. This rotational connection can be a bearing connection or a pin connection.

[0058] For a further explanation of the present invention, refer to Figure 1 , a nut 25 that moves along the first guide groove is provided therein, and its structure is:

[0059] A slider 27 that moves along the first guide groove is provided in the first guide groove, and the slider 27 is fixed to the nut 25.

[0060] For a further explanation of the present invention, refer to Figure 1 , the bolt 26 is coaxially fixed to the turntable 28, and the turntable 28 can be understood as a handle. By rotating the turntable 28, the user can conveniently rotate the bolt 26.

[0061] For a further explanation of the present invention, refer to Figure 1 , the traveling mechanism 2 is detachably fixed to one end of the traveling positioning support rod 6, and the other end of the traveling positioning support rod 6 is arranged on the second track 7.

[0062] For a further explanation of the present invention, refer to Figure 1 , the other end of the traveling positioning support rod 6 is arranged on the second track 7, and its structure is:

[0063] A clamping groove 61 is formed at the other end of the traveling positioning support rod 6, and an insulating wheel 62 is mounted in the clamping groove 61, and the insulating wheel 62 is in contact with the second track 7.

[0064] Among them, the traveling mechanism 2 is connected to one end of the traveling positioning support rod 6 in a detachable fixing manner, which enables the user to quickly disassemble and assemble according to needs, facilitating the transportation and maintenance of the equipment.

[0065] The other end of the traveling positioning support rod 6 is arranged on the second track 7. In this way, the traveling mechanism 2 can move stably on the second track 7.

[0066] Connection between the traveling positioning support rod 6 and the second track 7:

[0067] The insulating wheel 62 is in contact with the second track 7. By rolling of the insulating wheel 62, the traveling positioning support rod 6 can move smoothly along the second track 7. At the same time, the insulating wheel 62 can also prevent current conduction and improve safety.

[0068] For a further explanation of the present invention, the heating device includes a heating tile and a heat-insulating silicone heating sheet.

[0069] Among them, the installation of the heating tile: The heating tile is usually installed at the bottom or side wall of the storage tank because these positions can transfer heat to the lubricating medium more effectively.

[0070] If the bottom space of the storage tank is limited, multiple heating tiles can be selected to be installed on the side wall to ensure uniform heat distribution.

[0071] The installation of the heat-insulating silicone heating sheet: The heat-insulating silicone heating sheet can be installed on the outer wall of the storage tank, especially in areas where heat is easily dissipated, such as the top and sides.

[0072] The heat-insulating silicone heating sheet can fit the curved surface of the storage tank, providing a uniform heating effect while reducing heat loss.

[0073] The fixation of the heating tile: High-temperature-resistant screws or clamps can be used to fix the heating tile to the bottom or side wall of the storage tank.

[0074] Ensure that the fixing points are firm and reliable to avoid the heating tile falling off due to vibration or movement.

[0075] The fixation of the heat-insulating silicone heating sheet: Use high-temperature-resistant double-sided tape or special fixing straps to attach the heat-insulating silicone heating sheet to the outer wall of the storage tank.

[0076] Ensure that the heating sheet is flat and well-attached without bubbles or gaps to improve the heat transfer efficiency.

[0077] The power cords led out from the heating tile and the heat-insulating silicone heating sheet should be wrapped with high-temperature-resistant insulating materials to prevent damage caused by high temperature. The power cords should be introduced into the control box through waterproof connectors to ensure the safety of electrical connections.

[0078] A temperature controller should be installed inside the control box to monitor and control the temperature inside the storage tank to avoid overheating. The temperature controller can monitor the temperature inside the storage tank in real time through a temperature sensor and automatically adjust the power of the heating device according to the set value.

[0079] Install a temperature sensor inside the storage tank and use it in conjunction with the temperature controller to ensure that the temperature does not exceed the safe range. Set the over-temperature protection function so that once the temperature exceeds the set value, the power supply of the heating device is automatically cut off. All electrical connections should comply with safety standards, and moisture-proof and dust-proof connectors and cables should be used. The control box should have grounding protection to ensure the electrical safety of the equipment.

[0080] Installation steps

[0081] Prepare the required materials such as heating tiles, heat-insulating silicone heating sheets, high-temperature-resistant screws or clamps, double-sided tape or fixing straps, high-temperature-resistant insulating materials, temperature controllers, and temperature sensors. Confirm the installation location and fixing points of the storage tank.

[0082] Install the heating tile:

[0083] Place the heating tile at the bottom or side wall of the storage tank and fix it with high-temperature resistant screws or clamps. Ensure that the contact surface between the heating tile and the storage tank is flat without gaps.

[0084] Install the heat-insulating silicone heating sheet:

[0085] Attach the heat-insulating silicone heating sheet to the outer wall of the storage tank, especially the top and sides. Use high-temperature resistant double-sided tape or fixing straps to fix the heating sheet to ensure a flat and snug fit.

[0086] Connect the power cord:

[0087] Wrap the power cords led out from the heating tile and the heat-insulating silicone heating sheet with high-temperature resistant insulating materials. Introduce the power cords into the control box through waterproof connectors.

[0088] Install the temperature controller and temperature sensor:

[0089] Install the temperature sensor inside the storage tank to ensure that the sensor can accurately measure the temperature inside the storage tank. Connect the signal wire of the temperature sensor to the temperature controller and set the appropriate temperature range.

[0090] Testing and debugging:

[0091] Switch on the power supply, start the heating device, and check whether the readings of the temperature sensor are normal. Adjust the set value of the temperature controller to ensure that the temperature is within a safe range. Observe the operation of the heating device to ensure that there are no abnormal phenomena.

[0092] Through the above steps, it can be ensured that the heating device is safely and effectively installed on the storage tank, providing a stable heating effect for the lubricating medium.

[0093] As a further explanation of the present utility model, the spraying mechanism 3 is a nozzle.

[0094] As a further explanation of the present utility model, the spraying mechanism 3 is connected to the monitoring air supply system. The monitoring air supply system is installed on the walking bracket 22. The monitoring air supply system is connected to the air pump switch and the power supply. The air pump switch is used to control the start of the monitoring air supply system. Both the air pump switch and the power supply are installed on the walking bracket 22.

[0095] Among them, when spraying operations are required, the operator starts the monitoring air supply system through the air pump switch. The air pump starts to work, providing a stable gas pressure, which is delivered through the pipeline to the spraying mechanism 3. The spraying mechanism 3 atomizes and sprays the lubricating medium in the storage tank 1 using the gas pressure, and evenly sprays it onto the surface of the track. The monitoring air supply system can monitor the gas pressure in real time to ensure the stability and reliability of the spraying process.

[0096] Assume that lubrication operations need to be carried out on a new track section, and the specific steps are as follows:

[0097] Equipment preparation: Install the storage tank 1 on the walking bracket 22, and ensure that the nozzle is correctly installed at the discharge port of the storage tank.

[0098] Install the monitoring gas supply system including the air pump, air pump switch, and power supply on the walking bracket 22, and ensure that all connections are firm and reliable.

[0099] Start the monitoring gas supply system: Check whether the air pump switch and power supply are properly connected to ensure that the air pump can work normally. Start the monitoring gas supply system through the air pump switch, and the air pump starts to provide a stable gas pressure.

[0100] Start the walking mechanism:

[0101] Start the walking mechanism 2, so that the walking wheels 21 and the positioning rollers 23 move along the first track 4. Ensure that the insulating wheel 62 of the walking positioning rod 6 is in good contact with the second guide rail 7, and the walking mechanism 2 moves stably.

[0102] Spraying operation: As the walking mechanism 2 moves, the spraying mechanism 3 atomizes and sprays the lubricating medium in the storage tank 1 using gas pressure, and evenly sprays it onto the track surface. The operator can monitor the gas pressure and spraying effect in real time to ensure the smooth progress of the spraying process.

[0103] Complete the operation: After completing the spraying operation, stop the monitoring gas supply system through the air pump switch. Turn off the walking mechanism 2 and move the equipment to a safe place for storage.

[0104] Through the above settings, with the stable gas pressure provided by the monitoring gas supply system, the spraying mechanism 3 can spray the lubricating medium evenly and continuously, ensuring that the track surface is fully lubricated.

[0105] The air pump switch and power supply are integrated on the walking bracket 22, allowing the operator to easily start and stop the monitoring gas supply system, simplifying the operation process.

[0106] The monitoring gas supply system can monitor the gas pressure in real time, ensuring the stability and reliability of the spraying process, and avoiding uneven spraying or interruption caused by unstable gas pressure.

[0107] All key components, the air pump, air pump switch, and power supply, are installed on the walking bracket 22, facilitating daily maintenance and inspection, and extending the service life of the equipment.

[0108] The design of the monitoring gas supply system ensures the stability of the gas pressure, reduces potential safety hazards caused by pressure fluctuations, and improves the overall safety of the equipment.

[0109] Among them, a liquid level regulating device 8 is also installed on the storage tank 1. Specifically:

[0110] The components of the liquid level regulating device may include the following devices:

[0111] Liquid level sensor: Used to detect the liquid level height in the storage tank. Common liquid level sensors include float type, ultrasonic type, capacitive type, and pressure type, etc. It is usually installed on the side wall or bottom of the storage tank to ensure accurate detection of liquid level changes.

[0112] Liquid level controller: Used to receive the signal from the liquid level sensor and control the replenishment system or alarm system according to the set liquid level range. It can be a simple relay controller or an intelligent controller with a display screen and programming function. It is usually installed on the walking support 22 for easy operation and monitoring.

[0113] Replenishment system: Used to automatically replenish the lubricating medium when the liquid level is lower than the set value. It includes a replenishment pump, a replenishment pipeline, and a replenishment tank. The replenishment pump and the replenishment pipeline are installed near the storage tank, and the replenishment tank can be placed in other parts of the equipment or externally.

[0114] Alarm system: Used to send an alarm signal when the liquid level exceeds the set range (too high or too low). It can be an audible and visual alarm or a remote alarm system. It is usually installed in a place where the operator can easily see and hear, such as on the walking support 22.

[0115] Manual regulating valve: Used for the operator to manually adjust the liquid level when necessary. It is usually a manual valve installed on the replenishment pipeline.

[0120] Alarm system: Install the audible and visual alarm and connect it to the alarm output terminal of the liquid level controller.

[0121] Manual regulating valve: Install the manual regulating valve on the replenishment pipeline for easy manual adjustment by the operator.

[0122] Working principle:

[0123] Liquid level detection: The liquid level sensor continuously detects the liquid level height in the storage tank and sends the signal to the liquid level controller.

[0124] Liquid level control: The liquid level controller controls the supply pump of the replenishment system according to the set liquid level range. When the liquid level is lower than the set minimum value, the supply pump starts to replenish the lubricating medium into the storage tank; when the liquid level reaches the set maximum value, the supply pump stops.

[0125] Alarm prompt: When the liquid level exceeds the set range, the liquid level controller triggers the alarm system to send out audible and visual alarm signals to remind the operator to take measures.

[0126] Manual adjustment: When necessary, the operator can manually adjust the liquid level through the manual regulating valve to ensure that the liquid level in the storage tank is within the safe range.
