Description

[Technical Field]

[0001] The present invention relates to a lubricating device that applies lubricant to rails by spraying the lubricant onto the rails when a railway vehicle is traveling on a curved section. [Background technology]

[0002] When a railway vehicle is traveling on a curved section, there are known on-board devices that spray lubricants such as oil onto the rails to suppress wear and tear on the rails (e.g., Patent Document 1).

[0003] Such devices typically consist of a tank that stores lubricant and a sprayer that injects the lubricant onto the rails. The tank contains both the lubricant and a space (gas phase) above it. The pressure of the gas phase within the tank is used to deliver the lubricant to the sprayer. [Prior art documents] [Patent Documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 11-173495 [Overview of the project] [Problems that the invention aims to solve]

[0005] In the above-described apparatus, when the pressure in the gas phase of the tank is maintained at a constant pressure, the lubricant is delivered from the tank to the injector at a constant flow rate. However, many lubricants have properties such as viscosity that change with ambient temperature. Therefore, even if the pressure in the gas phase of the tank is maintained at a constant pressure, if the viscosity of the lubricant changes due to ambient temperature, the flow rate of the lubricant delivered from the tank to the injector will change. Consequently, the amount of lubricant injected from the injector onto the rail will also change.

[0006] For example, when the outside temperature is high, such as in summer, the viscosity of the lubricant is low, making it easier for the lubricant to be delivered from the tank to the sprayer. In this case, a large amount of lubricant is sprayed onto the rails. On the other hand, when the outside temperature is low, such as in winter, the viscosity of the lubricant is high, making it difficult for the lubricant to be delivered from the tank to the sprayer. In this case, a small amount of lubricant is sprayed onto the rails. Furthermore, changes in the viscosity of the lubricant due to changes in the outside temperature throughout the day also affect the amount of lubricant sprayed onto the rails. These factors cause changes in the amount of lubricant used.

[0007] However, it is desirable that the amount of lubricant used remain constant regardless of the ambient temperature. Therefore, the following methods are currently being implemented. A gas pipe is connected to the tank to supply gas to the gas phase inside the tank. A valve is located on this gas pipe. The operator adjusts the valve's opening in accordance with changes in ambient temperature to change the pressure in the gas phase inside the tank, thereby ensuring that the flow rate of the lubricant sent from the tank to the sprayer remains constant.

[0008] The above method places a burden on the worker because they have to adjust the valve opening every time the outside temperature changes.

[0009] The objective of this invention is to provide a device that can reduce the burden on workers. [Means for solving the problem]

[0010] The coating apparatus described herein is mounted on a railway vehicle and applies lubricant to rails by spraying the lubricant onto the rails, and comprises a tank for storing lubricant, a pressure adjusting means capable of adjusting the pressure of the gas phase in the tank, a sprayer for spraying the lubricant sent from the tank, a temperature detection unit for detecting the ambient temperature or the temperature of the lubricant in the tank, a pressure determination unit for determining the pressure of the gas phase in the tank based on the temperature information detected by the temperature detection unit, and a first control unit for controlling the pressure adjusting means based on the pressure determined by the pressure determination unit.

[0011] According to the above configuration, since the pressure in the gas phase portion of the tank is automatically adjusted according to the change in the outside air temperature, the burden on the operator can be reduced. Also, even if the outside air temperature changes, the amount of lubricant used can be made constant.

[0012] Also, in the above device, the pressure adjusting means may have a gas phase valve disposed in a gas phase gas pipe that sends gas to the gas phase portion in the tank, and the first control unit may be capable of adjusting the opening degree of the gas phase valve.

[0013] According to the change in the outside air temperature, by automatically adjusting the opening degree of the gas phase valve, the pressure in the gas phase portion of the tank is automatically adjusted, so that the burden on the operator can be reduced.

[0014] Also, in the above device, when the outside air temperature detected by the temperature detection unit is an arbitrary outside air temperature, or when the temperature of the lubricant in the tank detected by the temperature detection unit is an arbitrary temperature, it has a storage unit in which the pressure information of the gas phase portion in the tank that can send the lubricant to the injector at a predetermined flow rate from the tank is stored, and the pressure determination unit uses the pressure information stored in the storage unit to determine the pressure of the gas phase portion in the tank that can send the lubricant to the injector at a predetermined flow rate when the outside air temperature detected by the temperature detection unit or the temperature of the lubricant in the tank detected by the temperature detection unit.

[0015] By using the pressure information of the storage unit, the pressure of the gas phase portion in the tank at various outside air temperatures can be determined.

[0016] Also, in the above device, the pressure determination unit may be capable of determining the pressure of the gas phase portion in the tank based on the temperature information and the speed information of the railway vehicle.

[0017] For example, when a railway vehicle is passing through a curve, if the vehicle is moving at a high speed, the rails wear down more easily than when the vehicle is moving at a low speed. However, because the amount of lubricant injected per unit area onto the rails is less, the rails wear down even more easily. If the railway vehicle is moving at a speed higher than a predetermined speed, for example, by increasing the pressure in the gas phase of the tank to a higher pressure than the predetermined pressure, it is possible to prevent a decrease in the amount of lubricant injected per unit area onto the rails. When the speed of a railway vehicle is slower than a predetermined speed, the opposite occurs: the amount of lubricant injected per unit area onto the rail increases. Therefore, for example, by lowering the pressure of the gas phase in the tank to a pressure lower than a predetermined pressure, it is possible to prevent the amount of lubricant injected per unit area onto the rail from increasing.

[0018] In the above configuration, the pressure in the gas phase of the tank is automatically adjusted according to temperature information and the speed of the railway vehicle. This makes it possible to change the amount of lubricant used according to the vehicle speed while suppressing fluctuations in lubricant usage due to changes in ambient temperature.

[0019] Furthermore, the above-described apparatus may have a storage unit that stores pressure information of the gas phase in the tank, which allows the lubricant to be delivered from the tank to the sprayer at a predetermined flow rate when the ambient temperature and speed are arbitrary, or when the lubricant in the tank is at an arbitrary temperature and speed. The pressure determination unit may use the pressure information stored in the storage unit to determine the pressure of the gas phase in the tank, which allows the lubricant to be delivered from the tank to the sprayer at a predetermined flow rate when the ambient temperature and speed detected by the temperature detection unit are arbitrary, or when the lubricant in the tank is at an arbitrary temperature and speed.

[0020] By utilizing the pressure information from the memory unit, the pressure in the gas phase of the tank can be determined according to the ambient temperature and the speed of the railway vehicle.

[0021] Furthermore, the above-described device may also include a curve determination unit that determines whether the track is a curved section requiring lubricant injection based on the speed information and rotational angular velocity information of the railway vehicle, and a second control unit that can inject lubricant from the injection device based on the determination result of the curve determination unit.

[0022] With the above configuration, for example, the radius (R) of the curved section of the track is determined based on the speed information and rotational angular velocity information of the railway vehicle. Based on R, it is automatically determined whether the track is a curved section where lubricant needs to be sprayed onto the rails. If it is a curved section where lubricant spraying is necessary, lubricant is automatically sprayed onto the rails. The above series of actions are performed automatically. [Effects of the Invention]

[0023] This device can provide a solution that reduces the burden on workers. [Brief explanation of the drawing]

[0024] [Figure 1] This is a schematic diagram of a railway vehicle equipped with a coating device according to the first embodiment. [Figure 2] This is a diagram showing the configuration of the coating apparatus according to the first embodiment. [Figure 3] (a) and (b) are cross-sectional views of an example of a sprayer, where (a) shows the sprayer when no lubricant is being sprayed and (b) shows the sprayer when lubricant is being sprayed (during spraying). [Modes for carrying out the invention]

[0025] The embodiments will be described below with reference to the drawings.

[0026] [First Embodiment] The coating device according to this embodiment is a device that applies lubricant to rails by spraying the lubricant onto the rails. The coating device is mounted on a railway vehicle. In this specification, a railway vehicle may be simply referred to as "vehicle".

[0027] Figure 1 shows an example of the coating device 100 according to the first embodiment mounted on a railway vehicle 200. The vehicle width direction shown in Figure 1 is perpendicular to the longitudinal and height directions of the railway vehicle 200.

[0028] Figure 1 schematically shows the car body 201 and bogie 202 of a railway vehicle 200. The car body 201 is positioned above the bogie 202. The car body 201 is supported by the bogie 202. The bogie 202 has a bogie frame 203, a first wheel 204, and a second wheel 205. The first wheel 204 and the second wheel 205 are spaced apart in the vehicle width direction.

[0029] Railway vehicle 200 runs on the first rail 301 and the second rail 302. The first wheel 204 runs on the first rail 301, and the second wheel 205 runs on the second rail 302.

[0030] For example, when a railway vehicle 200 is traveling on a curve, the outer rail of the curve is subjected to lateral pressure from the flange of the wheel above it, causing wear on the inner surface of the outer rail head and the wheel flange. Therefore, in the curve, lubricant may be sprayed onto the inner surface of the outer rail head using the coating device 100. Also, when a railway vehicle 200 is traveling on a curve, lubricant may be sprayed onto the head of the inner rail of the curve to reduce the coefficient of friction of the inner rail head, thereby reducing the derailment coefficient of the outer rail. For the reasons stated above, when the railway vehicle 200 is traveling on a curve, lubricant is sprayed onto specific points on the rail, such as the top of the rail.

[0031] The coating device 100 includes, for example, a body mounting section 101 attached to the vehicle body 201, and a first sprayer 111 and a second sprayer 112 attached to the bogie 202.

[0032] The vehicle body mounting portion 101 may be located under the floor of the vehicle body 201, as shown in Figure 1. The vehicle body mounting portion 101 includes a plurality of components, as shown in Figure 2, which will be described later. The plurality of components may be housed in, for example, one or more housings, or they may be grouped together in one or more housings.

[0033] The first sprayer 111 is positioned, for example, to spray lubricant onto the head of the first rail 301. The first sprayer 111 is held, for example, on a first mounting bracket 401 attached to a bogie 202.

[0034] The second sprayer 112 is positioned to spray lubricant onto the head of the second rail 302, for example. The second sprayer 112 is held by a second mounting bracket 402 attached to the bogie 202, for example.

[0035] The first injector 111 and the second injector 112 may inject only lubricant, or they may inject lubricant and gas. When lubricant and gas are injected, injecting gas around the lubricant allows the lubricant to be concentrated on a specific point on the rail (e.g., the top of the rail). The gas may be, for example, air.

[0036] The type of lubricant is not particularly limited. For example, a general lubricant capable of suppressing rail wear (such as oil) may be used as the lubricant. The lubricant may contain solid or liquid wear inhibitors.

[0037] The configuration and arrangement of each component for mounting the coating device 100 on the railway vehicle 200 are not limited to those shown above and can be changed. Furthermore, the positions and inclinations of the first injector 111 and the second injector 112 are not limited to those shown in Figure 1 and can be changed.

[0038] The configuration of the coating apparatus 100 will be described below with reference to Figures 2 and 3.

[0039] [Coating device] Figure 2 schematically shows the configuration of the coating device 100. Above the dashed line is the body mounting section 101 which is attached to the vehicle body 201 (see Figure 1), and below the dashed line are the first sprayer 111 and the second sprayer 112, and the first rail 301 and the second rail 302 which are attached to the bogie 202 (see Figure 1).

[0040] Here, the coating apparatus 100 will be described by dividing it into detection means A, control means B, operating means C, and spraying means D. A to D are for convenience in explaining the configuration of the coating apparatus 100.

[0041] Detection means A includes a temperature detection unit 1, a speed detection unit 2, an angular velocity detection unit 3, and an acceleration detection unit 4. All or part of the speed detection unit 2, the angular velocity detection unit 3, and the acceleration detection unit 4 do not have to be part of the coating device 100. In other words, all or part of the speed detection unit 2, the angular velocity detection unit 3, and the acceleration detection unit 4 do not have to be part of the coating device 100. All or part of the speed detection unit 2, the angular velocity detection unit 3, and the acceleration detection unit 4 may, for example, be attached to or mounted on the railway vehicle 200 as a separate unit from the coating device 100. All or part of the speed detection unit 2, the angular velocity detection unit 3, and the acceleration detection unit 4 may, for example, be attached to or mounted on the railway vehicle 200 for a purpose other than applying lubricant to the first rail 301 and the second rail 302. Furthermore, detection means A may have other detection means.

[0042] Control means B includes a pressure determination unit 11, a first storage unit 12, a first control unit 13, a curve determination unit 21, a second storage unit 22, a second control unit 23, and a curve outside determination unit 31. Control means B may also have parts that perform processing or storage other than those described above.

[0043] Actuator C includes a gas tank 50 and a lubricant tank (tank) 60, among others. Actuator C also includes pipes and valves, among other things. Actuator C may have other parts besides those mentioned above.

[0044] The injection means D includes a first injection device 111 and a second injection device 112.

[0045] The following will explain A through D above. Note that the explanation of control means B may use a part of actuating means C and a part of injection means D, so the following will be explained in the order of detection means A, actuating means C, injection means D, and control means B.

[0046] [Detection means A] (Temperature detection unit 1) The temperature detection unit 1 detects the ambient temperature. The temperature detection unit 1 may be, for example, a thermometer or a temperature sensor. The ambient temperature information detected by the temperature detection unit 1 is sent to the pressure determination unit 11 of the control means B.

[0047] The temperature detection unit 1 can be installed anywhere as long as it can detect the ambient temperature. The ambient temperature information detected by the temperature detection unit 1 is used to estimate the viscosity of the lubricant in the lubricant tank 60 and to determine the pressure of the gas phase of the lubricant tank 60, which is affected by the viscosity of the lubricant in the lubricant tank 60. For this reason, the temperature detection unit 1 may be placed near the lubricant tank 60.

[0048] (Speed ​​detection unit 2) The speed detection unit 2 detects the vehicle's speed. The speed detection unit 2 may be, for example, a speedometer or a speed sensor. The vehicle speed information detected by the speed detection unit 2 may be sent to the pressure determination unit 11 and the curve determination unit 21 of the control means B, or it may be sent only to the curve determination unit 21. The speed detection unit 2 can be mounted anywhere as long as it can detect the vehicle's speed.

[0049] (Angular velocity detection unit 3) The angular velocity detection unit 3 detects the rotational angular velocity of the vehicle. The angular velocity detection unit 3 may be, for example, a vibration-type angular velocity sensor (such as a vibration-type gyro sensor) used for detecting the rotational angular velocity of railway vehicles. The rotational angular velocity information of the vehicle detected by the angular velocity detection unit 3 is sent to the curve determination unit 21 of the control means B. The angular velocity detection unit 3 can be mounted anywhere as long as it can detect the rotational angular velocity of the vehicle.

[0050] (Acceleration detection unit 4) When the vehicle's direction of travel is considered forward, the acceleration detection unit 4 can detect the vehicle's acceleration in the longitudinal direction. The acceleration detection unit 4 may be, for example, an acceleration sensor commonly used for detecting vehicle acceleration. The vehicle acceleration information detected by the acceleration detection unit 4 is sent to the curve outside determination unit 31 of the control means B. The acceleration detection unit 4 can be mounted anywhere as long as it can detect the vehicle's acceleration in the longitudinal direction.

[0051] Detection by each detection unit may be performed, for example, continuously or at regular intervals. The information detected by each detection unit may be sent to the control means B.

[0052] [Operating means C] (Gas tank) The gas tank 50 is a tank that stores gas. The type of gas is not particularly limited. The gas could be, for example, air. The gas tank 50 could also be, for example, an air reservoir that stores compressed air. There may be pipes or other means to supply gas to the gas tank 50.

[0053] (Lubricant tank) The lubricant tank (tank) 60 is a tank in which lubricant is stored. As shown in Figure 2, when lubricant is stored in the lubricant tank 60, the lubricant and a space above it exist within the lubricant tank 60. In this specification, the space above the lubricant is sometimes referred to as the "gas phase," and the part in which the lubricant exists is sometimes referred to as the "liquid phase."

[0054] The lubricant tank 60 is configured such that the stored lubricant is sent from the lubricant tank 60 to the first injector 111 and the second injector 112 by the pressure in the gas phase. For example, if the viscosity of the lubricant does not change, when the pressure in the gas phase is at a predetermined pressure, the lubricant is sent from the lubricant tank 60 to the first injector 111 and the second injector 112 at a constant flow rate. For example, if the viscosity of the lubricant does not change, when the pressure in the gas phase is higher than the predetermined pressure, the flow rate of the lubricant increases. A pressure tank may be used as the lubricant tank 60, for example.

[0055] There may also be pipes for supplying lubricant to the lubricant tank 60 and pipes for discharging lubricant from the lubricant tank 60.

[0056] (Gas pipe) A gas pipe 70 is connected to a gas tank 50. The gas pipe 70 branches into two pipes along the way. One of the branched gas phase pipes, 70A, is connected to the gas phase section of a lubricant tank 60. The other branched injection gas pipe, 70B, further branches into two pipes (first injection gas pipe 70B1 and second injection gas pipe 70B2). The first injection gas pipe 70B1 is connected to the first injection device 111. The second injection gas pipe 70B2 is connected to the second injection device 112.

[0057] Of the gas flowing from the gas tank 50 into the gas pipe 70, some is sent to the lubricant tank 60 through the gas phase gas pipe 70A, and the remaining gas flows into the injection gas pipe 70B. Of the gas flowing into the injection gas pipe 70B, some is sent to the first injection device 111 through the first injection gas pipe 70B1, and the remaining gas is sent to the second injection device 112 through the second injection gas pipe 70B2.

[0058] (Gas phase valve) A gas phase valve 71 is located in the gas phase pipe 70A between the gas tank 50 and the lubricant tank 60. The opening, closing, and adjustment of the gas phase valve 71 change the presence or absence of gas sent from the gas tank 50 to the gas phase section of the lubricant tank 60, as well as the amount of gas and the gas flow velocity. This changes the pressure in the gas phase section of the lubricant tank 60.

[0059] (Pressure adjustment means) A pressure adjustment means is configured, which allows for adjustment of the pressure in the gas phase of the lubricant tank 60, by comprising the gas tank 50, the gas phase pipe 70A, and the gas phase valve 71.

[0060] (First gas valve, second gas valve) A first gas valve 72 is located on the first injection gas pipe 70B1. A second gas valve 73 is located on the second injection gas pipe 70B2.

[0061] When the first gas valve 72 is open, gas is sent to the first injector 111 through the first injection gas pipe 70B1. When the first gas valve 72 is closed, no gas is sent to the first injector 111.

[0062] When the second gas valve 73 is open, gas is sent to the second injector 112 through the second injection gas pipe 70B2. When the second gas valve 73 is closed, no gas is sent to the second injector 112.

[0063] (Fluid tube) A fluid pipe 80 is connected to the liquid phase of the lubricant tank 60. The fluid pipe 80 branches into two pipes midway. One of the branched pipes is connected to the first sprayer 111, and the other pipe is connected to the second sprayer 112. The lubricant in the lubricant tank 60 is delivered to the first sprayer 111 and the second sprayer 112 through the fluid pipe 80.

[0064] The types of valves described above—the gas phase valve 71, the first gas valve 72, and the second gas valve 73—are not particularly limited. These valves may be, for example, solenoid valves. Other types of valves may also be present.

[0065] In addition to the gas pipe 70, gas phase gas pipe 70A, injection gas pipe 70B, first injection gas pipe 70B1, second injection gas pipe 70B2, and fluid pipe 80, there may be other pipes through which gas or lubricant passes. The branching points of the gas pipe 70 and fluid pipe 80 are not limited to the parts shown in Figure 2. Also, although the gas pipe 70 and fluid pipe 80 shown in Figure 2 are branched pipes, multiple pipes may be used instead of branched pipes.

[0066] [Injection means D] The first injector 111 injects lubricant onto the first rail 301. The second injector 112 injects lubricant onto the second rail 302. The first injector 111 and the second injector 112 are arranged apart, for example, in the vehicle width direction. The first injector 111 and the second injector 112 are, for example, nozzles.

[0067] Figures 3(a) and 3(b) show examples of sprayers, specifically the first sprayer 111 and the second sprayer 112. Figure 3(a) shows the system when no lubricant is being sprayed, and Figure 3(b) shows the system when lubricant is being sprayed.

[0068] The sprayer comprises a sprayer body 121 and a piston 122.

[0069] As shown in Figure 3(a), the sprayer body 121 has a gas passage 121x and a lubricant passage 121p. One end of the gas flow path 121x (the upper end in Figure 3(a)) is connected to the first injection gas pipe 70B1 or the second injection gas pipe 70B2 shown in Figure 2. The other end of the gas flow path 121x (the lower end in Figure 3(a)) is a gas injection port. The piston 122 is positioned below the gas flow path 121x, so that the gas flow path 121x is formed around the axis of the piston 122. One end of the lubricant passage 121p (the upper end in Figure 3(a)) is in communication with the fluid pipe 80 shown in Figure 2. The other end of the lubricant passage 121p (the lower end in Figure 3(a)) is in communication with the lubricant passage 122p of the piston 122, as shown in Figure 3(b).

[0070] The piston 122 has a lubricant passage 122p, as shown in Figure 3(a). The lower end of the lubricant passage 122p in Figure 3(a) is a lubricant injection port, as shown in Figure 3(b).

[0071] When no gas is supplied to the gas passage 121x, the piston 122 blocks the gas passage 121x (see Figure 3(a)). In this case, the lubricant passage 121p of the injector body 121 and the lubricant passage 122p of the piston 122 are not in communication. Therefore, no lubricant is injected from the injector.

[0072] When gas is supplied to the gas passage 121x, as shown in Figure 3(b), the gas causes the piston 122 to rise, opening the gas passage 121x from one end to the other. This causes gas to be ejected from the injector. Additionally, the lubricant passage 121p of the injector body 121 and the lubricant passage 122p of the piston 122 are opened, causing lubricant to be ejected from the injector. By injecting gas to surround the ejected lubricant, the lubricant can be concentrated on a specific location (for example, the head of the rail).

[0073] According to the above configuration, when gas is supplied to the injector, lubricant is injected from the injector, and when gas is not supplied to the injector, lubricant is not injected from the injector. However, the configurations of the first injector 111 and the second injector 112 are not limited to this configuration. Furthermore, the first injector 111 and the second injector 112 are not limited to the configurations shown in Figures 3(a) and 3(b).

[0074] [Control means B] (Pressure determination section) The pressure determination unit 11 shown in Figure 2 can determine the pressure in the gas phase of the lubricant tank 60 based on the temperature information detected by the temperature detection unit 1. The pressure determination unit 11 can also determine the pressure in the gas phase of the lubricant tank 60 based on the speed information of the railway vehicle detected by the speed detection unit 2. Furthermore, the pressure determination unit 11 can determine the pressure in the gas phase of the lubricant tank 60 based on the temperature information detected by the temperature detection unit 1 and the speed information (speed of the railway vehicle) detected by the speed detection unit 2.

[0075] For example, based on the temperature information detected by the temperature detection unit 1, the pressure determination unit 11 may determine the pressure in the gas phase portion of the lubricant tank 60 that can send the lubricant at that temperature from the lubricant tank 60 to the fluid pipe 80 at a predetermined flow rate. As another example, based on the temperature information detected by the temperature detection unit 1, the pressure determination unit 11 may estimate the viscosity of the lubricant at that temperature and determine the pressure in the gas phase portion of the lubricant tank 60 that can send the lubricant with the estimated viscosity from the lubricant tank 60 to the fluid pipe 80 at a predetermined flow rate. In this specification, the above-mentioned another example is also referred to as "determining the pressure in the gas phase portion of the lubricant tank 60 based on the temperature information detected by the temperature detection unit 1".

[0076] Also, as an example, the pressure determination unit 11 may determine the pressure in the gas phase portion of the lubricant tank 60 with respect to the speed of the vehicle by the following method. For example, when the speed of the vehicle is less than a certain speed (less than Va [km / h]), the pressure determination unit 11 determines that the pressure in the gas phase portion of the lubricant tank 60 is set to a certain pressure (P A [kPa]), and when the speed of the vehicle is within a certain speed range (Va to Vb [km / h]), the pressure determination unit 11 may determine that the pressure in the gas phase portion of the lubricant tank 60 is set to another certain pressure (P B [kPa]). Further, when the speed of the vehicle exceeds a certain speed (when exceeding Vb [km / h]), the pressure determination unit 11 may determine that the pressure in the gas phase portion of the lubricant tank 60 is set to another certain pressure (P C [kPa]). Thus, the pressure determination unit 11 may determine the pressure in the gas phase portion of the lubricant tank 60 corresponding to the vehicle speed range. As another example, when the speed of the vehicle is a certain speed (V X1 [km / h] or less), the pressure determination unit 11 determines that the pressure in the gas phase portion of the lubricant tank 60 is set to a certain pressure (P X1 [kPa]), and when the speed of the vehicle is another certain speed (V X2 [km / h]), the pressure in the gas phase portion of the lubricant tank 60 is determined to be another certain pressure (P X2 [kPa]). For example, for any vehicle speed (V[[ID=二十ー]] Xn [km / h]), there is a corresponding pressure (P Xn [kPa]) in the gas phase portion of the lubricant tank 60 (where n is a natural number), and for any vehicle speed (VXn [km / h]) The pressure in the gas phase of the lubricant tank 60 corresponding to (P Xn [kPa]) may be determined to be V. X1 and P X1 , V X2 and P X2 , , , V Xn and P Xn As shown above, there may be multiple combinations of the speed of any vehicle and the corresponding pressure in the gas phase of the lubricant tank 60. Also, the combination of the speed of any vehicle and the corresponding pressure in the gas phase of the lubricant tank 60 is V X1 Less than (or V X1 In the following cases, P X1 , V Xn When it exceeds (or V Xn (The above) is P Xn The combination may include a range for the vehicle speed, etc. In this way, the pressure determination unit 11 may determine the pressure of the gas phase portion of the lubricant tank 60 corresponding to the vehicle speed.

[0077] The pressure determination unit 11 may determine the pressure in the gas phase of the lubricant tank 60 based on the temperature information detected by the temperature detection unit 1 and the speed information (speed of the railway vehicle) detected by the speed detection unit 2. In other words, the pressure determination unit 11 may determine the pressure in the gas phase of the lubricant tank 60 by considering both the temperature information detected by the temperature detection unit 1 and the speed information (speed of the railway vehicle) detected by the speed detection unit 2. For example, the pressure determination unit 11 may determine the pressure by combining the above determinations.

[0078] The pressure determination unit 11 may, for example, determine the pressure in the gas phase of the lubricant tank 60 at regular intervals based on temperature information and / or speed information detected at regular intervals. Alternatively, the pressure in the gas phase of the lubricant tank 60 may be determined each time the temperature information detected by the temperature detection unit 1 changes, in other words, each time the ambient temperature changes. Alternatively, the pressure in the gas phase of the lubricant tank 60 may be determined each time the speed information detected by the speed detection unit 2 changes, in other words, each time the vehicle speed changes.

[0079] The pressure determination unit 11 may determine the pressure of the gas phase of the lubricant tank 60 using the information described above, as well as the information stored in the first storage unit 12, which will be described later. The pressure information determined by the pressure determination unit 11 is sent to the first control unit 13.

[0080] (1st memory) The first storage unit 12 stores information that can be used to determine the pressure of the gas phase of the lubricant tank 60. Specifically, the first storage unit 12 stores information (pressure information) of the pressure of the gas phase of the lubricant tank 60 corresponding to the temperature (ambient temperature). The first storage unit 12 may also store information (pressure information) of the pressure of the gas phase of the lubricant tank 60 corresponding to the vehicle's speed. Furthermore, the first storage unit 12 may also store information (pressure information) of the pressure of the gas phase of the lubricant tank 60 corresponding to both the temperature (ambient temperature) and the vehicle's speed.

[0081] For example, the first storage unit 12 may store pressure information (pressure information) of the gas phase of the lubricant tank 60 that allows lubricant to be delivered from the lubricant tank 60 to the first injector 111 or the second injector 112 at a predetermined flow rate when the ambient temperature is "any ambient temperature". In this case, pressure information corresponding to various ambient temperatures may be stored in the first storage unit 12.

[0082] As another example, the first storage unit 12 may store information on the viscosity of the lubricant at an arbitrary ambient temperature (viscosity information) and information on the pressure of the gas phase of the lubricant tank 60 that enables the lubricant to be delivered from the lubricant tank 60 to the first injector 111 or the second injector 112 at a predetermined flow rate when the lubricant has an arbitrary viscosity (pressure information). In this case, the first storage unit 12 may store information on viscosity at various ambient temperatures and information on pressure at various viscosity levels. In this specification, the above example is also referred to as "information on the pressure of the gas phase in the tank that enables the lubricant to be delivered from the tank to the injector at a predetermined flow rate when the ambient temperature is arbitrary."

[0083] As pressure information of the gas phase portion of the lubricant tank 60 corresponding to the vehicle's "speed," for example, when the vehicle's speed is below a certain speed (less than Va [km / h]), information on the "pressure" of the gas phase portion of the lubricant tank 60 (pressure information) (P) is provided so that the lubricant can be delivered from the lubricant tank 60 to the first injector 111 or the second injector 112 at a "predetermined flow rate." A [kPa]) may be stored in the first memory unit 12. Furthermore, when the vehicle speed is within a certain speed range (Va~Vb [km / h]), information on the "pressure" of the gas phase of the lubricant tank 60 (pressure information) (P) allows the lubricant to be delivered from the lubricant tank 60 to the first injector 111 or the second injector 112 at a different "predetermined flow velocity" (P B [kPa]) may be stored in the first memory unit 12. Furthermore, when the vehicle speed exceeds a certain speed (when it exceeds Vb [km / h]), information on the "pressure" of the gas phase of the lubricant tank 60 (pressure information) (P) allows for the delivery of lubricant from the lubricant tank 60 to the first injector 111 or the second injector 112 at another "predetermined flow velocity" (P C [kPa]) may be stored in the first memory unit 12.

[0084] Another example is when the vehicle speed reaches a certain speed (V X1 When the speed is less than [km / h], information on the "pressure" of the gas phase of the lubricant tank 60 (pressure information) (P X1 [kPa]) may be stored in the first storage unit 12. Also, the vehicle speed may be another speed (V X2 When the speed is [km / h], information on the "pressure" of the gas phase of the lubricant tank 60 (pressure information) (P X2 [kPa]) may be stored in the first memory unit 12.

[0085] Furthermore, as pressure information of the gas phase portion of the lubricant tank 60 corresponding to the "outside temperature" and the "speed" of the vehicle, for example, information (pressure information) of the "pressure" of the gas phase portion of the lubricant tank 60 that enables the lubricant to be delivered from the lubricant tank 60 to the first injector 111 or the second injector 112 at a "determined flow velocity" when the "outside temperature" and the vehicle is at a certain "speed" may be stored in the first storage unit 12. Information (pressure information) of the "pressure" of the gas phase portion of the lubricant tank 60 for various combinations of outside temperature and "speed" may also be stored in the first storage unit 12.

[0086] The first storage unit 12 may store all of the following: (i) information on the pressure of the gas phase of the lubricant tank 60 corresponding to the outside temperature (pressure information), (ii) information on the pressure of the gas phase of the lubricant tank 60 corresponding to the vehicle's speed (pressure information), and (iii) information on the pressure of the gas phase of the lubricant tank 60 corresponding to both the outside temperature and the vehicle's speed (pressure information). Alternatively, one or two of (i) to (iii) may be stored. Furthermore, the pressure information stored in the first storage unit 12 is not limited to the above (i) to (iii).

[0087] The aforementioned "arbitrary ambient temperature," "predetermined flow velocity," "pressure," "ambiency," "arbitrary viscosity," "velocity," and "predetermined velocity" may be values ​​of 1 or ranges. A range may be, for example, a range with an upper and lower limit (A or more and B or less, greater than A and less than B, etc.), a range with only an upper limit, or a range with only a lower limit. The same applies below.

[0088] (First Control Unit) The first control unit 13 controls the pressure adjustment means based on the pressure determined by the pressure determination unit 11. Specifically, the first control unit 13 adjusts the opening degree of the gas phase valve 71 so that the pressure in the gas phase of the lubricant tank 60 reaches the pressure determined by the pressure determination unit 11. The first control unit 13 may also perform the opening and / or closing operations of the gas phase valve 71.

[0089] (Curve judgment section) The curve determination unit 21 determines whether the track is a curved section where lubricant must be sprayed onto the rails, based on the speed information detected by the speed detection unit 2 and the rotational angular velocity information detected by the angular velocity detection unit 3. A "curved section where lubricant must be sprayed onto the rails" is a curved section where the rails are prone to wear due to the radius of the curve, and therefore it is better to spray lubricant onto the rails. Hereinafter, curved sections where lubricant must be sprayed onto the rails may be referred to as "sharp curves".

[0090] The curve determination unit 21, for example, calculates the radius (R) of the curved section of the track based on the vehicle's speed information and rotational angular velocity information, and determines whether the track is a sharp curve based on R. In this case, each time the speed information detected by the speed detection unit 2 changes, it calculates the radius (R) of the curved section and determines whether the track is a sharp curve based on R.

[0091] The curve determination unit 21 may determine the radius R of the curved section at regular time intervals and determine whether the track is a sharp curve based on R, or it may determine the radius R of the curved section each time the rotational angular velocity information detected by the angular velocity detection unit 3 changes and determine whether the track is a sharp curve based on R.

[0092] The curve determination unit 21 may use the information stored in the second storage unit 22 (described later) to determine whether the track is a sharp curve based on the speed information detected by the speed detection unit 2 and the rotational angular velocity information detected by the angular velocity detection unit 3.

[0093] The determination result of the curve determination unit 21 is sent to the second control unit 23. The curve determination unit 21 may determine whether the track is a sharp curve or not, and send either determination result to the second control unit 23.

[0094] (Second memory) The second memory unit 22 stores information that can be used to determine whether a track is a sharp curve. The second memory unit 22 may store, for example, the range of R for determining whether a track is a sharp curve, the range of R for determining whether a track is not a sharp curve, and a threshold value for R for determining whether a track is a sharp curve or not.

[0095] (Curve outside judgment part) The curve outer determination unit 31 determines the outer edge of a curve (including sharp curves) based on the acceleration information detected by the acceleration detection unit 4. For example, the outer edge of a curve may be determined based on the acceleration information in the longitudinal direction of the vehicle detected by the acceleration detection unit 4.

[0096] The curve outside determination unit 31 may determine the outside of the curve at regular time intervals, or it may determine the outside of the curve each time the acceleration information detected by the acceleration detection unit 4 changes.

[0097] Furthermore, information that can be used to determine the outside of the curved section may be stored in a memory unit (not shown). The curved section determination unit 31 may use the information stored in the memory unit (not shown) to determine the outside of the curved section based on the acceleration information detected by the acceleration detection unit 4.

[0098] The determination result from the curve outside determination unit 31 is sent to the second control unit 23.

[0099] (Second Control Unit) The second control unit 23 opens or closes the first gas valve 72 or the second gas valve 73 based on the determination result of the curve determination unit 21 and the determination result of the curve outside determination unit 31.

[0100] For example, if the curve determination unit 21 determines that it is a sharp curve, the second control unit 23, based on the information from the curve outside determination unit 31 regarding the outside of the curve, opens the first gas valve 72 in the first injection gas pipe 70B1 or the second gas valve 73 in the second injection gas pipe 70B2 (hereinafter sometimes referred to as the "outside gas valve") connected to the injection device (first injection device 111 or second injection device 112) that sprays lubricant to the outside of the curve. Subsequently, if the curve determination unit 21 determines that it is not a sharp curve, the second control unit 23 closes the open outside gas valve (first gas valve 72 or second gas valve 73).

[0101] [Operation of the coating device] Next, an example of the operation of the coating device 100 will be described.

[0102] The temperature detection unit 1 detects the temperature. The velocity detection unit 2 detects the velocity. The angular velocity detection unit 3 detects the rotational angular velocity. The acceleration detection unit 4 detects the acceleration. The detected information is sent to the control means B, as shown in Figure 2.

[0103] <Pressure adjustment in the gas phase of the lubricant tank 60> (1) The pressure determination unit 11 determines the pressure in the gas phase of the lubricant tank 60 based on the ambient temperature information detected by the temperature detection unit 1. The determined pressure information is sent to the first control unit 13. The first control unit 13 adjusts the opening degree of the gas phase valve 71 based on the determined pressure information.

[0104] The above series of operations are performed automatically. This eliminates the need for operators to adjust the opening of the gas phase valve 71 in accordance with changes in ambient temperature, thereby reducing the burden on operators. Furthermore, the amount of lubricant used can be automatically kept constant even when the ambient temperature changes.

[0105] Furthermore, when the pressure determination unit 11 determines the pressure, it uses the pressure information stored in the first storage unit 12 to determine the pressure, thereby enabling it to handle various ambient temperatures.

[0106] (2) The pressure determination unit 11 may determine the pressure of the gas phase of the lubricant tank 60 based on the speed information detected by the speed detection unit 2. The determined pressure information is sent to the first control unit 13. The first control unit 13 adjusts the opening degree of the gas phase valve 71 based on the determined pressure information.

[0107] The above series of operations are performed automatically. This means that, for example, if the vehicle is traveling at a high speed while passing through a sharp curve, the amount of lubricant injected will automatically increase, thus reducing rail wear. Also, if the vehicle's speed decreases while passing through a sharp curve, the amount of lubricant injected will automatically decrease, reducing the amount of lubricant used in areas where it is not needed as much.

[0108] Furthermore, the pressure determination unit 11 can handle various speeds by determining the pressure using pressure information corresponding to the vehicle speed stored in the first storage unit 12.

[0109] (3) The pressure determination unit 11 may determine the pressure of the gas phase of the lubricant tank 60 based on the ambient temperature information detected by the temperature detection unit 1 and the speed information detected by the speed detection unit 2. The determined pressure information is sent to the first control unit 13. The first control unit 13 adjusts the opening degree of the gas phase valve 71 based on the determined pressure information. This series of operations is performed automatically. This eliminates the need for operators to adjust the opening of the gas phase valve 71 in accordance with changes in ambient temperature, thereby reducing the burden on operators. Furthermore, it automatically determines the flow velocity considering the ambient temperature and vehicle speed, and automatically delivers the lubricant to the first injector 111 and the second injector 112 at that flow velocity. In addition, it can change the amount of lubricant used according to the vehicle speed while suppressing fluctuations in the amount of lubricant used due to changes in ambient temperature.

[0110] Furthermore, the pressure determination unit 11 can handle various speeds by determining the pressure using pressure information corresponding to the vehicle speed stored in the first storage unit 12.

[0111] As described in (1) to (3) above, the pressure in the gas phase of the lubricant tank 60 is automatically adjusted. For example, the pressure determination of the pressure determination unit 11 and the opening degree adjustment of the gas phase valve 71 described in (1) to (3) above may be performed at regular intervals. Also, in (1) or (2) above, the pressure determination of the pressure determination unit 11 and the opening degree adjustment of the gas phase valve 71 may be performed each time the outside temperature changes. Also, in (2) or (3) above, the pressure determination of the pressure determination unit 11 and the opening degree adjustment of the gas phase valve 71 may be performed each time the vehicle speed changes. The pressure determination of the pressure determination unit 11 and the opening degree adjustment of the gas phase valve 71 described in (1) to (3) above may be performed at times other than those listed above.

[0112] <Lubricant spraying> The curve determination unit 21 determines whether the track being traveled is a sharp curve requiring lubrication, based on the speed information detected by the speed detection unit 2 and the rotational angular velocity information detected by the angular velocity detection unit 3. The curve outside determination unit 31 determines whether the outside of a curve (including sharp curves) is the curved section. These judgment results are sent to the second control unit 23.

[0113] When the second control unit 23 receives a determination that it is a sharp curve section requiring lubricant injection, and also receives a determination that it is outside the curve section (including the sharp curve section), it opens the "outer gas valve" (first gas valve 72 or second gas valve 73) of the sharp curve section. As shown in Figure 3(a), gas is supplied to one of the injection devices, and as shown in Figure 3(b), lubricant is injected onto the outer rail. Subsequently, when the second control unit 23, as shown in Figure 2, receives a determination that it is not a sharp curve section, it closes the "outer gas valve" (first gas valve 72 or second gas valve 73) that was open. This stops the injection of lubricant onto the rail.

[0114] The above series of operations are performed automatically while the vehicle is in motion. As a result, lubricant is automatically sprayed in sharp curves where it is needed. In addition, for example, lubricant is automatically sprayed only on the outer rail, which is prone to wear in sharp curves. Furthermore, the configurations in which lubricant is sprayed in sharp curves and in which lubricant is sprayed on the outer rails, etc., are not limited to the above-described configurations.

[0115] [Second Embodiment] The difference between the coating apparatus 1100 according to the second embodiment and the first embodiment is that the coating apparatus 1100 according to the second embodiment has a temperature detection unit 1001 that detects the temperature of the lubricant in the lubricant tank (tank) 60, instead of the temperature detection unit 1 that detects the ambient temperature in the first embodiment. The other configurations of the coating apparatus 1100 according to the second embodiment are the same as those of the first embodiment, and therefore the same reference numerals are used for the same components as in the first embodiment described above. Furthermore, the following explanation will be given with reference to Figures 1 to 3 used in the first embodiment.

[0116] (Temperature detection unit) The temperature detection unit 1001 detects the temperature of the lubricant in the lubricant tank (tank) 60 shown in Figure 2. The temperature detection unit 1001 may be, for example, a thermometer or a temperature sensor. The temperature detection unit 1001 is installed, for example, inside the lubricant tank (tank) 60 shown in Figure 2. The temperature information of the lubricant in the lubricant tank (tank) 60 detected by the temperature detection unit 1001 is sent to the pressure determination unit 11 of the control means B.

[0117] The pressure determination unit 11 shown in Figure 3 can determine the pressure in the gas phase of the lubricant tank 60 based on the temperature information detected by the temperature detection unit 1001. The pressure determination unit 11 can also determine the pressure in the gas phase of the lubricant tank 60 based on the speed information of the railway vehicle detected by the speed detection unit 2. Furthermore, the pressure determination unit 11 can determine the pressure in the gas phase of the lubricant tank 60 based on the temperature information detected by the temperature detection unit 1001 and the speed information (speed of the railway vehicle) detected by the speed detection unit 2. An example of the pressure determination method is the same as the example of the method described in the first embodiment.

[0118] (1st memory) The first storage unit 12 shown in Figure 3 stores information that can be used to determine the pressure of the gas phase of the lubricant tank 60. Specifically, the first storage unit 12 stores information (pressure information) of the "pressure" of the gas phase of the lubricant tank 60 corresponding to the temperature of the lubricant in the lubricant tank 60 (in this embodiment, this may be simply referred to as "temperature"). The first storage unit 12 may also store information (pressure information) of the "pressure" of the gas phase of the lubricant tank 60 corresponding to the "speed" of the vehicle. In addition, the first storage unit 12 may also store information (pressure information) of the "pressure" of the gas phase of the lubricant tank 60 corresponding to the "temperature" (temperature of the lubricant in the lubricant tank 60) and the "speed" of the vehicle. Examples of information stored in the first storage unit 12 are similar to the examples of information described in the first embodiment, where "temperature" (ambient temperature) or "ambient temperature" is replaced with "temperature" (temperature of the lubricant in the lubricant tank (tank) 60) or "temperature of the lubricant in the lubricant tank (tank) 60".

[0119] The configurations shown in Figures 1 to 3, other than those described above, are the same as those of the first embodiment.

[0120] The coating apparatus 1100 according to the second embodiment operates, for example, as follows. The pressure determination unit 11 shown in Figure 2 determines the pressure in the gas phase of the lubricant tank (tank) 60 based on the temperature information of the lubricant in the lubricant tank (tank) 60 detected by the temperature detection unit 1. The determined pressure information is sent to the first control unit 13. The first control unit 13 adjusts the opening degree of the gas phase valve 71 based on the determined pressure information. This series of operations is performed automatically. The coating apparatus 1100 according to the second embodiment also performs operations other than those described above. Examples of operations other than those described above for the coating apparatus 1100 according to the second embodiment are the same as the examples of operations of the coating apparatus 100 according to the first embodiment, in which "temperature detection unit 1", "outside temperature", etc. are replaced with "temperature detection unit 1001", "temperature of the lubricant in the lubricant tank (tank) 60", etc.

[0121] The coating device 1100 according to the second embodiment, like the coating device 100 according to the first embodiment, eliminates the need for the operator to adjust the opening of the gas phase valve 71 (see Figure 2) in accordance with changes in ambient temperature, thereby reducing the burden on the operator. Furthermore, the amount of lubricant used can be automatically kept constant even when the ambient temperature changes. In addition, the coating device 1100 according to the second embodiment provides the same effects as the coating device 100 described in the first embodiment.

[0122] Although embodiments of the present invention have been described above with reference to the drawings, it should be understood that the specific configurations are not limited to these embodiments. The scope of the present invention is indicated not by the above description but by the claims, and all modifications within the meaning and scope equivalent to the claims are included.

[0123] For example, the configuration of the coating apparatus 100 is not limited to the configuration shown in Figures 2, 3(a), and 3(b).

[0124] For example, the positions and configurations of the gas phase valve 71, the first gas valve 72, and the second gas valve 73 shown in Figure 2 are not particularly limited. For instance, instead of the first gas valve 72 and the second gas valve 73, a three-way valve or the like may be present at the branching point of the gas pipe 70. Also, valves other than those described above may be arranged in the piping.

[0125] Furthermore, the configuration capable of spraying lubricant is not limited to the configurations shown in Figures 2, 3(a), and 3(b). The configuration capable of spraying lubricant is not limited to a configuration in which lubricant is sprayed when gas is supplied to the first injector 111 and / or the second injector 112.

[0126] Furthermore, in the above embodiment, the pressure regulating means for adjusting the pressure in the gas phase of the lubricant tank 60 includes a gas tank 50. However, the pressure regulating means may include one that can supply a gas other than the gas tank 50. Alternatively, a gas supply means mounted on the vehicle for another purpose may be used instead of the gas tank 50.

[0127] Furthermore, in the above embodiment, gas can be supplied from a single gas tank 50 to the gas phase of the lubricant tank 60, the first injector 111, and the second injector 112. However, the gas supply means that supplies gas to the gas phase of the lubricant tank 60 and the gas supply means that supplies gas to the first injector 111 and the second injector 112 may be different.

[0128] Furthermore, the first control unit 13 and the second control unit 23 shown in Figure 2 may be composed of a single control unit.

[0129] Furthermore, the first storage unit 12 and the second storage unit 22 shown in Figure 2, and the other storage units, may all be composed of one storage unit. Also, the first storage unit 12 and the second storage unit 22 shown in Figure 2, and some of the other storage units, may all be composed of one storage unit.

[0130] Furthermore, there may be a pressure detection unit capable of detecting the pressure in the gas phase of the lubricant tank 60. The pressure information detected by the pressure detection unit may be sent to the first control unit 13. The first control unit 13 may adjust the opening degree of the gas phase valve 71 based on the pressure information detected by the pressure detection unit, in addition to the pressure information determined by the pressure determination unit 11.

[0131] Furthermore, there may be a flow velocity detection unit capable of detecting the flow velocity of the lubricant passing through the fluid pipe 80. For example, the flow velocity information detected by the flow velocity detection unit may be sent to the first storage unit 12, thereby updating the pressure information in relation to ambient temperature and the pressure information in relation to the viscosity of the lubricant stored in the first storage unit 12. Alternatively, the flow velocity information detected by the flow velocity detection unit may be sent to the first control unit 13. The first control unit 13 may adjust the opening degree of the gas phase valve 71 based on the pressure information determined by the pressure determination unit 11 as well as the flow velocity information detected by the flow velocity detection unit.

[0132] Furthermore, the coating apparatus according to the present invention may include both a temperature detection unit 1 for detecting ambient temperature and a temperature detection unit 1001 for detecting the temperature of the lubricant in the lubricant tank (tank) 60. The present invention includes cases in which the coating apparatus includes either or both of the temperature detection unit 1 for detecting ambient temperature and the temperature detection unit 1001 for detecting the temperature of the lubricant in the lubricant tank (tank) 60. When the coating apparatus includes both the temperature detection unit 1 and the temperature detection unit 1001, for example, the coating apparatus may be configured so that if one of the temperature detection units fails to detect the temperature, the other temperature detection unit is used to operate the coating apparatus. Also, when the coating apparatus includes both the temperature detection unit 1 and the temperature detection unit 1001, the temperature detection unit 1 for detecting ambient temperature may be used for purposes other than the coating apparatus. In this case, the temperature detection unit 1 for detecting ambient temperature does not have to be housed in the same casing as other components of the coating apparatus, for example. Similarly, in the coating apparatus having a temperature detection unit 1 for detecting ambient temperature as described in the first embodiment, the temperature detection unit 1 may also be used for purposes other than the coating apparatus, and it does not have to be housed in the same enclosure as other components of the coating apparatus.
