Description

  The present invention relates to an on-vehicle type lubricant application method and apparatus for a railway vehicle, and more particularly, when a vehicle is traveling on a curved road, the lubricant is applied from a vehicle side to a specific part of a wheel, for example, at a boundary between a flange and a tread. The present invention relates to an on-vehicle type lubricant application method and apparatus for applying a lubricant.

  A vehicle-mounted type equipped with an electromagnetic pump that pumps lubricating oil and a lubricant application nozzle that applies lubricant by injecting the lubricating oil pumped by this electromagnetic pump to a specific part of the rail or the wheel axial direction of the wheel Is known (see, for example, Patent Document 1).

According to this, in the method of installing the lubricant applying device individually for each curved path of the rail, Installation is uneconomical. 2. There is a problem in safety because it is arranged close to the vehicle wheel or moved by vibration of the rail. 3. The installation and adjustment of the lubricant application device is delicate and its maintenance is also difficult. Such a problem can be solved. Also, although it is an on-vehicle type, a spray nozzle that sucks up the liquid lubricant in the lubricating oil tank using compressed air supplied by opening a solenoid valve that leads to the air tank of the vehicle, and is placed close to the wheel or rail 1. Spray type to spray and apply lubricant. Piping for lubricating oil and air piping are necessary, and the piping structure is complicated. 2. Since the lubricating oil is sprayed in the form of a mist, the surrounding environment is polluted. 3. This scattering causes lubricant to be applied to the tread surface of the wheel or the top of the rail other than the desired location, causing the wheel to slip relative to the rail. Can be solved (see, for example, Non-Patent Document 1).

  However, conventionally known in-vehicle lubricant applicators, including the above-mentioned ones, have a dedicated mounting structure for mounting on axle boxes and carts and are equipped with a position correction mechanism. In particular, the structure and assembly work are complicated and expensive, and work such as inspection and repair is also complicated.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle-mounted lubricant application method and apparatus for a railway vehicle that can stably apply a lubricant to a predetermined lubricant application position with a simple and inexpensive apparatus using a wheel as a lubricant application object. It is in.

  In order to achieve the above-described object, the on-vehicle type lubricant application method for a railway vehicle according to the present invention is provided with a lubricant application means attached to a tread cleaning tool that is mounted on a vehicle and cleans the tread of a wheel. One feature is that the lubricant is applied to a specific portion of the wheel by the lubricant applying means attached to the tool.

  As a lubricant application device that achieves such a method, a tread cleaning tool that is mounted on a vehicle and cleans the tread of the wheel, and a lubricant application that is attached to the tread cleaning tool and applies a lubricant to a specific part of the wheel. One feature suffices to be provided with the means and the control means for controlling the lubricant application by the lubricant application means and the stop of the lubricant application.

  In such a configuration, since the lubricant is applied to the wheel from the lubricant applying means attached to the tread cleaning tool of the wheel, a dedicated mounting structure for mounting the lubricant applying means on the vehicle is unnecessary, and the tread cleaning tool itself It is mounted on the vehicle with a support structure that has a mechanism that corrects the position of the wheel so that it does not shift in the axial direction of the wheel while facing the tread surface of the wheel and does not shift in the direction perpendicular to the axis. Therefore, simply by attaching the lubricant application means to the tread cleaning tool, the tread cleaning tool position accuracy can be kept stable with respect to a specific part in the axial direction, which is an important point of lubricant application to the wheels. The lubricant can be stably applied to a predetermined position of the wheel with a simple and inexpensive device.

As a lubricant application means, a lubricant such as an oil-impregnated material attached to the abrasive is used, and the lubricant is applied by bringing the lubricant into contact with the wheel by the operation of the abrasive.
Lubricant itself is in contact with the wheel to apply the lubricant, but by attaching it to the abrasive, the abrasive can be separated from the wheel by the operation of the abrasive, and the lubricant can be applied and stopped. Lubricant can be applied without a dedicated operating mechanism. In addition to the oil, the lubricant may be a slippery component forming the lubricating body itself, or so-called talc can be used.

  As a device for realizing this, the lubricant applying means is a lubricating body such as an oil impregnated attached to the abrasive, and the control means makes the lubricant contact the wheel by the advancing and retreating operation of the abrasive, and the contact is released. Thus, it may be configured to control the lubricant application and the stop of the lubricant application.

  Lubricant is in contact with the wheel during the cleaning operation of the abrasive to provide lubricant. In a further configuration, the lubricant is brought into contact with the wheel during the cleaning of the abrasive and no special operation is performed. A lubricant can be applied to the surface.

  As a device for realizing this, the control means may be configured to contact and release the wheel simultaneously with the contact and release of the abrasive wheel with the tread.

  As a lubricant application means, an injection tool for injecting oil attached to the abrasive is used, and oil is injected to the wheel through this injection tool to apply the lubricant. In a further configuration, the lubricant is applied to a specific part of the wheel. Since the application can be performed without contact, maintenance due to wear or the like is not required. In addition, it is non-contact but attached to the abrasive, so that it is possible to apply the lubricant without removing the aim from a position very close to the wheel, and without causing waste and surrounding pollution.

  As a device for realizing this, the lubricant applying means is an injection tool for injecting oil, and the control means controls the injection of oil through the injection tool to control the application of lubricant and the stop of the application of lubricant. Any configuration may be used.

  Further objects and features of the present invention will become apparent from the following detailed description and drawings. Each feature of the present invention can be used alone or in combination in various combinations as much as possible.

  Without a dedicated attachment structure for the lubricant application means, the position of the tread cleaning tool can be kept stable with respect to a specific part of the wheel as it is, and the lubricant can be stably placed at a predetermined position on the wheel with a simple and inexpensive device. Can be granted. Work such as assembly, inspection and repair is also simplified.

  Embodiments of an on-vehicle type lubricant application method and apparatus for a railway vehicle according to the present invention will be described in detail with reference to FIGS. 1 to 12 to provide an understanding of the present invention.

  The vehicle-mounted lubricant application method for a railway vehicle according to the present embodiment includes the lubricant application device shown in FIGS. 1 to 5, the lubricant application device shown in FIGS. 6 and 7, and FIGS. 8 and 9. The lubricant applying device 3 is attached to the tread cleaning tool 2 that is mounted on the vehicle and cleans the tread of the wheel 1, and the lubricant is attached to the tread cleaning tool 2. The tool 3 applies a lubricant to a specific portion of the wheel 1, mainly a boundary 1c between the tread surface 1a and the flange 1b as shown in FIG. Thereby, since the lubricant is applied to the wheel 1 from the lubricant applicator 3 attached to the tread cleaning tool 2 of the wheel 1, a dedicated mounting structure for mounting the lubricant applicator 3 on the vehicle is unnecessary, and the tread cleaning is performed. Support having a mechanism for correcting the position of the tool 2 itself facing the tread surface 1a of the wheel 1 so as not to be displaced with respect to the direction of the axis 16 of the wheel 1 and whether it is almost displaced even in the direction perpendicular to the axis 16 Since it is mounted on a vehicle with a structure, the lubricant applicator 3 is attached to the tread cleaning tool 2 only to a specific portion that is an important point for applying the lubricant to the wheel 1, that is, the boundary 1c. On the other hand, since the position accuracy of the tread cleaning tool 2 can be kept stable, the lubricant can be stably applied to a predetermined position of the wheel 1, such as the above-mentioned extremely limited boundary 1c, with a simple and inexpensive device. be able to. Also, assembly, inspection, and repair work are simplified.

  In the example shown in FIGS. 1 to 5, the tread cleaning tool 2 is mounted on the disc brake device 5 mounted on the carriage 4, and is not only in the axial direction but also in the direction perpendicular to the axis with respect to the tread 1 a of the wheel 1. Positioned and mounted so as not to swing. Specifically, the disc brake device 5 has a pair of left and right brake disc portions 6 provided on both side surfaces of the wheel 1 and a pair of brake members 8 supported on the carriage 4 and opened and closed by an actuator 7. In addition, a U-shaped support frame 9 is provided, and braking is applied by sandwiching the brake disk portion 6 between the brake members 8. The tread cleaning tool 2 is arranged with respect to the disc brake device 5 so as not to interfere with each other by using the space 12 provided therein, and the advancing and retreating axis 15 of the abrasive 14 in the tread cleaning tool 2 is substantially horizontal and the wheels 1, a U-shaped support frame 11 as a support member of the brake member 8 in the disc brake device 5 is attached to a bracket 13 that supports the carriage 4, and the abrasive 14 is attached to the tread 1 a of the wheel 1. They are facing each other. However, it goes without saying that the support member of the brake member 8 may employ a pair of brake levers that are opened and closed with a brake member by an actuator (not shown) instead of the U-shaped support frame 11. There is no particular limitation on the support structure, the opening / closing mechanism, and the mounting structure of the support member to the cart 4. The tread cleaning tool 2 can be attached not only to the bracket 13 but also to a support member such as the U-shaped support frame 11 or to both the bracket 13 and the support member. Depending on the case, it can also be attached to the cart 4 itself or over the cart 4 itself.

  The bracket 13 is fixed between the side beams 21 of the carriage 4 by welding or the like to a horizontal beam 23 installed in parallel to the axle 22, and the vertical symmetry axis 24 of the control 8 is supported at a position almost passing the axis 16 of the wheel 1. They are opened and closed by an actuator 7 such as a hydraulic cylinder. The bracket 13 has a box shape projecting from the horizontal beam 23 located slightly higher than the axle 22 toward the wheel 1 with a broadened shape in which the upper surface is substantially horizontal and the lower surface is inclined obliquely downward, and is below the horizontal beam 23. Windows 26 and 27 are provided on the front and rear sides of the portion, and a space 12 that penetrates the bracket 13 back and forth and connects from the base through window 20 of the U-shaped support frame 11 to the forked portion is formed. That is, a space 12 penetrating the entire disc brake device 5 in the front-rear direction is formed.

  As shown in FIGS. 1 to 4, the tread cleaning tool 2 includes a cylinder 32 having a mounting portion 31 and an abrasive receiving rod 33 inserted into the cylinder 32 so as to extend and contract. The abrasive 14 is supported on the protruding end of the rod 33 from the cylinder 32. The torque receiving rod 33 is acted on a return spring 30 shown in FIG. When air is sent from the air supply port 36 into an air chamber (not shown) of the cylinder 32, the torque receiving rod 33 is extended against the return spring 30 and presses the abrasive 14 against the tread surface 1 a of the wheel 1 for cleaning. When the air in the air chamber is released, the torque receiving rod 33 is returned with the abrasive 14 by the urging of the return spring, and the abrasive 14 is pulled away from the tread surface 1 a of the wheel 1. The tread cleaning tool 2 is also provided with a latch device 38 for regulating the retracted position of the abrasive receiving rod 33 as shown in FIG.

  As shown in FIG. 1, the attachment portion 31 of the tread cleaning tool 2 is welded with a leg portion 31a so as to stand up with an H-shaped cross section, for example, as shown in FIG. A rectangular mounting seat 31b is applied and welded, and mounting holes are provided in the mounting seat 31b. Thus, the mounting seat 31b of the mounting portion 31 of the tread cleaning tool 2 disposed in the space 12 of the disc brake device 5 is applied to the bottom of the bracket 13 of the disc brake device 5 from above as shown in FIGS. However, it is fastened and attached by the mounting hole and the bolt 37.

  As described above, the wheel tread cleaning 23 is arranged in the space 12 in the disc brake device 5 and attached to the bracket 13 of the disc brake device 5, so that in addition to the mounting bracket and outfitting space of the tread cleaning tool 2 alone, auxiliary A support mechanism becomes unnecessary. Therefore, the support structure is simplified, and the outfitting space is smaller than the conventional one. Moreover, the vertical axis 15 of the abrasive brake 14 of the tread cleaning tool 2 is substantially horizontal and the axis 16 of the wheel 1 without disturbing the installation condition in which the vertical axis 24 of the disc brake device 5 substantially passes through the axis 16 of the wheel 1. Can be made to work in a direction almost passing through. Therefore, not only the required installation conditions of the disc brake device 5 but also the best installation conditions of the tread cleaning tool 2 are satisfied, and both the brake function and the tread cleaning function are stable and highly reliable.

  Further, since the space 12 penetrates the disc brake device 5 from the opposite wheel 1 side to the wheel 1 side, the tread cleaning tool 2 protrudes forward and backward from the bracket 13 of the disc brake device 5 as shown in FIG. Well, it works on the wheel 1 in normal form. Therefore, the tread cleaning tool 2 itself needs only to fit the mounting seat 31b to the bracket 13, and no special design change is required.

  In another example shown in FIGS. 6 and 7, the tread cleaning tool 2 is attached to a U-shaped support frame 11, which is a support member for the brake control 8. Specifically, the attachment portion 31 provided in the cylinder 32 of the tread cleaning tool 2 is bolted to the bottom wall 20 a of the base through window 20 of the U-shaped support frame 11 with a bolt 37. Other structures are not particularly different from the previous example, and common members are denoted by the same reference numerals, and redundant descriptions are omitted.

  In another example shown in FIGS. 8 and 9, the disc brake device 5 is supported by a bracket 41 fixed by welding or the like to the cross beam between the side beams of the carriage 4, and the tread cleaning is performed immediately above the disc brake device 5. The tool 2 is provided and attached to the uppermost portion of the bracket 41 by means of a bolt 42 from above, so that the advance / retreat axis 15 of the abrasive 14 passes through the axis 16 of the wheel 1 substantially.

  As a result, the abrasive 14 works stably on the tread 1a with less vibration load regardless of which side the wheel 1 rotates. Also, the disc brake device 5 has an upper and lower symmetric axis 24 that is substantially horizontal and substantially passes through the axis 16 of the wheel 1, so that even if the carriage 4 and the wheel 1 move relative to each other up and down, the disc brake device 5 is stable with little deviation. Work. Further, when the carriage 4 and the wheel 1 move relative to each other in the vertical direction, the gap between the abrasive 14 and the wheel 1 fluctuates, so that the pressing force of the abrasive 14 against the tread surface 1a of the wheel 1 fluctuates from time to time. Although the child 14 becomes unstable, the abrasive 14 is supported by being suspended by another auxiliary support mechanism 44. Therefore, also in this example, the tread cleaning tool 2 works while maintaining a substantially stable positional relationship with respect to the wheel 1.

  The examples shown in FIGS. 1 to 5, the examples shown in FIGS. 6 and 7, and the examples shown in FIGS. 8 and 9, the lubricant applicator is embedded in the abrasive 14 as the lubricant applicator 3. The injection tool 51 for injecting the oil attached thereto is used, and the oil is injected to a specific portion of the wheel 1 through the injection tool 51 to apply the lubricant. Thereby, since the lubricant can be applied to the specific part of the wheel 1 in a non-contact manner, maintenance due to wear or the like becomes unnecessary. In addition, it is non-contact but attached to the abrasive, so that it is possible to apply the lubricant without removing the aim from a position very close to the wheel, and without causing waste and surrounding pollution. In addition, when the injection tool 51 is embedded in the abrasive 14, there is an advantage that it is easy to accurately face the necessary specific part such as the boundary 1 c of the wheel 1 from the nearest place without any interruption.

  By the way, in contrast to the polishing surface of the abrasive 14 retreating with time, the gap with respect to the wheel 1 is stabilized by restricting the retracted position of the abrasive 14 with the latch device 38. If the position of the injection tool 51 relative to the abrasive 14 is moved backward, the distance to the wheel 1 becomes stable. Such a backward operation can also be performed manually. However, if the injection tool 51 is attached to a fixing member such as the cylinder 32 of the tread cleaning tool 2, such consideration is not necessary, but it is necessary not to interfere with the cleaning operation of the abrasive 14. This can be easily dealt with by providing a local relief on the abrasive 14 to avoid the injection tool 51.

  In particular, the application of the lubricant is determined automatically based on the relationship between the approach speed or the passing speed at the time when the vehicle enters the curved road, or at a necessary timing according to a predetermined program. FIG. 12 shows an example of the control means 52 that automatically determines such conditions and applies the lubricant.

  To explain this, as shown in FIG. 12, the oil 113 in which the back pressure applied to the oil storage tank 111 is adjusted to the optimum pressure by turning on and off the high pressure electromagnetic valve 122 according to the speed in the oil storage tank 111 is changed to the wheel 1. And an electromagnetic valve control means for controlling supply of air for opening and closing the electromagnetic valve 121 of the injection tool 51 based on information from the curve detector 114a. The vehicle 101 includes 114 and a left and right traveling direction discriminating means 146 that discriminates the left and right traveling direction from detection information from the non-contact type gyro sensor 103 that receives the yaw rate of the vehicle 101 and detects the yaw rate in a non-contact manner. . In particular, the control means 52 determines a curve by the curve detector 114 from the yaw rate detected by the gyro sensor 103 and causes the oil 113 to be injected in accordance with this determination. Thereby, accurate lubricant application based on the detection of the yaw rate of the vehicle 101 by the non-contact type gyro sensor 103 can be performed automatically and stably.

  Preferably, a speed sensor 115 for detecting the speed of the vehicle 101 and a temperature sensor 116 for detecting the ambient temperature are provided, and the control means 52 is controlled by the electromagnetic valve control means 114 from a curve detector 114a registered therein. The oil 113 is injected in accordance with the information of the curve, speed, and ambient temperature. This makes it possible to avoid lubricant application timing shifts due to speed differences, excessive or insufficient lubricant application amounts, changes in oil viscosity due to differences in ambient temperature, and excessive or insufficient lubricant application amounts. It is always possible to guarantee proper lubricant application. The oil storage tank 111, the oil supply means 112, and various sensors 103, 115, and 116, the traveling direction determination means 146 that constitutes the control means 52, the curve detector 114, and the like are integrated as an underfloor equipment 117 of the vehicle 101. Yes.

  Here, the injector 51 includes a left wheel 1 and a right wheel 1, both of which are opened and closed by supplied air controlled by the left and right solenoid valves 121, and the oil supply means 112 is an oil storage tank. If oil 113 in 111 is always supplied by pressurized air and the solenoid valve 121 is opened, the oil 113 can be injected immediately, and the pressure increase according to the speed of the vehicle 101 by the pressure increase solenoid valve 122 in the middle of the oil supply path. The lubricant can be applied at an injection speed according to the speed of the vehicle. The oil supply means 112 supplies compressed oil stored in the air tank 124 to the oil storage tank 111 after reducing the compressed air to the lubricant application reference pressure by the pressure reducing valve 125. Thereby, the existing air tank 124 used for other applications can be shared to obtain compressed air having a lubricant application reference pressure, and automatic lubricant application can be performed without the need for a special compressed air source. However, the injection method of the oil 113 is not limited to the above case, and the injection of the oil 113 through the injection tool 51 employs a method in which the oil 113 is pumped and injected by a pump such as an electromagnetic pump described in Patent Document 1. be able to. Moreover, although the injection tool 51 has shown the example attached to each tread surface cleaning tool 2, specifically, two or more with respect to the abrasive 14, specifically, it can increase / decrease, 1 There may be one, or three or more.

  In the example shown in FIG. 10, a lubricant 61 such as an oil-impregnated material attached to the abrasive 14 is used as the lubricant applicator 3, and the lubricant 61 is brought into contact with the wheel 1 by the operation of the abrasive 14. Granting is done. As a result, the lubricant 61 itself is brought into contact with the wheel 1 to apply the lubricant, and the lubricant 61 is attached to the abrasive 14 so that it is separated from the wheel 1 by the operation of the abrasive 14. The lubricant can be applied and stopped, and the lubricant can be applied without a dedicated operation mechanism. As the oil-containing material, a soft oil retaining material such as felt or a hard oil retaining material having open cells such as sintered metal can be used. Further, depending on the material, it can also serve as the abrasive 14. The lubricant 61 may be used in an oil-impregnated state, or may be used while maintaining a predetermined oil-impregnated state by replenishing the lubricant.

  Note that the lubricant may be a slippery component forming the lubricating body 61 in addition to the lubricating oil, and so-called talc can be used as such a lubricating body 61. The talc is also known as a wax, and one of its uses is a lubricant. The talc has the hardness of 1 and is the softest among stones. When rubbed against a specific part of the wheel 1, its components are scraped off and adhere to the surface of the specific part of the wheel 1. Works as a lubricant.

  In the example shown in FIG. 10, the lubrication body 61 using a hard oil retaining material such as talc is fitted and bonded to a portion of the abrasive 14 cut out, and bonded to the abrasive base 14a. Attached with a rivet and a holding bracket, it is used in a state where both sides are the same. In this case, the lubricating body 61 works simultaneously with the abrasive 14 being pressed against the tread surface 1a of the wheel 1 for polishing and cleaning, and has an advantage that the two functions need not be controlled separately. If the hardness and wear resistance of the lubricant 61 are lower than that of the abrasive 14, the normal function of the tread cleaning by the abrasive 14 is not impaired, and the wear of the lubricant 61 has a large contact area and the hardness and wear resistance. The wear amount of the high abrasive 14 is adjusted. The lubricating body 61 does not wear beyond the wear amount of the abrasive 14. If the relationship between the hardness and the degree of wear is opposite to that described above, the abrasive 14 having a large contact area and low hardness may be worn prior to the lubricant body 61 and the polishing action on the tread 1a of the wheel 1 may be disturbed.

  In the example shown in FIG. 11, the lubricant 61 is caused to appear and disappear from the abrasive 14 by an actuator 71 such as a solenoid provided on the abrasive base 14 a. As a result, the lubricant can be applied to the wheel 1 at the same time as the abrasive 14 cleaning the tread or simultaneously.
