Description

Train wheel lubricator and the wheel lubrication system using the same

The present invention relates to a wheel oiling device for a train and a wheel oiling system using the same, and in particular, a device for applying lubricant to a wheel by a rotary brush, and a device installed on a straight portion of a track to apply lubricant to an entire wheel of a vehicle. In addition, the present invention relates to a wheel lubrication system that can reduce frictional noise and abrasion of the rail caused by the contact between the wheel and the rail by automatically being held on the rail when the train travels on a curved track of the track.

As is well known, when the train travels on a curved track, the centrifugal force causes the train wheels to exert a transverse pressure on the outer rails of the track, thereby causing friction between the wheels and the rails in contact. In addition, the train is inevitably steered along the curved direction as if the curved high rail and the wheel flanges slide in friction contact with each other. This friction causes continuous wear of the wheels and rails, Generates metallic friction noises that are unpleasant to passengers while driving.

On the other hand, in order to reduce this phenomenon, when a train passes a curved track, a grease is used to apply a lubricant such as grease to the friction surface between the rail and the wheel. When the driving wheel passes the grease jet point, it is buried and applied to the curved track of the track.

One of the oil drainers is an oil drainage method that attaches and drains the oil drainage plate from which grease is discharged at the time point of the relief curve of the track. The grease is discharged to the rail side through the hole formed in the oil drainage plate. have. However, this method is usually installed at the point of relaxation curve where centrifugal force is applied because the wheel can be in contact with the side of the greased rail, in which case it passes through the spot where grease is already in contact with the wheel and the rail. As a result, the required oiling position is scattered without proper oiling, thereby reducing the oiling effect and contaminating the surrounding area of the track due to scattered grease. In addition, maintenance of the drainage plate nozzle hole through which grease is discharged frequently occurs.

Another oiler type spraying oiling method is a method of spraying grease on the side of the rail through an injection gun. Such spraying oilers can spray grease at the proper oiling point on the side of the rail, but due to the nature of the spraying type, the grease has a low viscosity, so it is insufficient to extend the application distance, and a large amount of grease splashes to provide an optimal oiling effect. it's difficult.

As a result, the above two types of oil lubricator extends the coating distance by applying the grease to the rail by applying the grease to the rail side, but since the grease contacts only a part of the first wheel of the train, the rail / wheel There are many limitations to prolong wear life by preventing wear.

On the other hand, in addition to the above-described methods, there is also a vehicle-mounted pottery that is installed directly in the vehicle and passes through the curve by applying a solid lubricant to the friction surface of the wheel by a sensor, which is installed when not installed on all wheels Only wheels can be oiled to reduce the effect, the cost of solid lubricants are expensive, and the scattering in the tunnel can cause environmental pollution. The complexity of the device and the weight of the installation also contributes to the increased power consumption costs of the train.

The present invention has been made to solve the above problems, and provides a device for applying a lubricant to the wheel by the rotary brush, but installed in the position just before the curved track of the track, when the train runs the track of the track automatically It is an object of the present invention to provide a wheel oiling system capable of lubricating the entire wheel of a vehicle to maximize the oiling effect as well as to reduce friction noise and abrasion of the rail caused by the contact between the wheel and the rail.

The wheel oiling apparatus of the train of the present invention for achieving the above object is a main frame installed on the inner surface of the rail; Drive pulleys and driven pulleys respectively installed at both ends of the main frame; An indirect power transmission member connected to the drive pulley and the driven pulley to rotate; A drive motor for rotating the drive pulley; It is provided with a plurality of intervals on the upper portion of the indirect power transmission member is provided with a lubricating brush for applying a lubricant to the wheel and a lubricant supply means for supplying a lubricant to the petroleum brush.

In the above-described configuration, the main frame is installed on the inner surface of the rail, each of the oil brush is preferably composed of two to three stages of the outer end of the relatively large key brush and the inner end of the relatively small key brush. Do.

Furthermore, a surplus lubricant removing member for removing the lubricant excessively attached to the oiling brush may be further provided.

In addition, it is preferable that a height adjusting means for adjusting the height of the oil brush or adjusting means for adjusting the tension of the indirect power transmission member is provided.

The indirect power transmission member may be implemented as a chain or a belt.

On the other hand, the wheel oiling system of the train according to another feature of the present invention

Oiling device which is installed on each of the inner side surfaces of both rails with a plurality of rotatable oiling brush to apply a lubricant to the wheel passing through it;

A train passage detecting unit detecting whether the train passes;

Lubricant supply means for supplying lubricant to the oiling brush;

Timer and timer to set operating time and idle time

A control means for controlling the lubricant supply means to supply lubricant to the oiling brush while the train passage detection signal is input from the train passage detecting part, and controlling the oiling device to rotate the oiling brush. Is done.

According to the wheel oiling device of the train of the present invention and the wheel oiling system using the same, it is possible to increase the oiling effect by accurately applying lubricant to the wheels of the train being driven by the rotating brush, as well as oiling in consideration of the circumferential distance of the wheels. By determining the length of the device, it is possible to lubricate all the wheels as well as the circumference of each wheel of the train, thereby effectively reducing the wear of the rails and wheels and the friction noise of the rails and wheels at low cost.

Hereinafter, with reference to the accompanying drawings will be described in detail a wheel oiling apparatus and a wheel oiling system using the same according to a preferred embodiment of the present invention.

In the above configuration, the oiling apparatus is preferably installed on the inner side of the straight portion just before the curved portion of the rail 210 starts. The reason is that since the train is not subjected to centrifugal force in the straight portion of the rail 210, it is possible to secure a constant distance between the wheel 220 and the rail 210 (see FIG. 5 to be described later), and grease is applied to the gap. This is because grease can be applied to the flange of the wheel 220 by inserting the brush 150. Furthermore, unlike the related art, the main reason for oiling the wheel 220 using the oiling brush 150 can be precisely oiled at the point where friction occurs between the rail 210 by appropriately selecting its installation position. This is because the oiling effect can be maximized.

Moreover, it is preferable to install the oiling device on both rails 210 of the rail so that the oiling effect can be sufficiently exerted by only one oiling even in the reverberation curve connecting the right curve and the left curve. 220 is in contact with the rail 210 by the centrifugal force and the steering force during the running of the curved portion, whereby grease is transferred to the rail 210 is buried.

Next, the train passage detection unit 330 may be installed at a position immediately before the start of the curved track of the track at a distance from the rail 210, for example, a sensor such as a light sensor of light transmission or light reflection type. By operation it is possible to detect whether the train has passed. The train passage detection unit 330 may be accommodated together with the storage box and the control unit in a control panel installed at a distance from the rail (210). The grease supply system is a grease discharge pump (not shown) for discharging grease stored in the reservoir to the outside, a grease discharge hose 252 serving as a discharge path of the grease, and a grease installed on both rails 210 at the same pressure. It may be made to include a distributor 250 to distribute evenly to, the grease dispensed in this way will be supplied to the oiling brush 150 through a grease discharge nozzle (not shown) in the future.

As shown in Figures 4 to 9, the oiling apparatus according to the present invention is made of a hollow steel or the like, the main frame 100, the main frame 100 is fixed in the longitudinal direction on the inner surface of the rail (210) Axial coupling to the drive chain sprocket 120 and the driven sprocket 130, the drive sprocket 120 and the driven sprocket 130 and the chain 140, the drive sprocket 120 is rotatably installed at both ends of the inside) Chain drive motor 110 for rotating the drive sprocket 120, a plurality of oil brushes 150, which are installed at intervals above each other over the entire circumference of the chain 140 to rotate together with the chain 140, oil A grease discharge nozzle 170 for discharging grease to the brush 150 and a fastening (clamping) bracket 102 for fastening and fixing the main frame 100 to the inner surface of the rail 210 may be formed.

In the above configuration, the length of the main frame 100 may be determined in consideration of the diameter of the wheel 210 so that grease can be applied over the entire wheel 210 when the wheel 210 passes through the oiling apparatus. . Next, the oiling brush 150 may be formed of polyethylene (PE) or PP (polypropylene) fiber having good elasticity, and may be installed at equal intervals over the entire circumference of the chain 140. Furthermore, in consideration of the wheel structure having a smoothly curved flange, the oil brush 150 has an internal and external two-stage structure, while the outer end is formed with a relatively large key, while the inner end is formed with a relatively small key (FIGS. 5 and 7). By minimizing damage to the oil brush 150, grease may be properly applied to the wheel flanges. Furthermore, it is desirable to allow the oiling brush 150 to be detachable from the chain 140 by a screw so that it can be replaced when the wear reaches its limit.

Next, the fastening bracket 102 forms a groove that fits perfectly to the rail bottom shape so that the main frame 100 is not separated from the rail 210 by vibration generated during train operation, and the groove is inserted into the rail bottom. It may be made of a structure that is fixed by the bolt fastening after. Next, the chain drive motor 110 may be implemented as a geared motor having a reduction coupling 112 coupled to the rotation shaft thereof, whereby the rotational force of the chain drive motor 110 is appropriately reduced while the rotation speed thereof is appropriately reduced. Will be delivered to the drive sprocket 120. The grease discharge nozzle 170 is installed on the rotational path of the oil brush 150 at the end of the main frame 100 where the driven sprocket 130 is installed, for example, to discharge grease directly to the oil brush 150. . In FIGS. 7 and 8, reference numerals 180 and 180 ′ denote excess grease removing members for removing excess grease that may be excessively buried in the oiling brush 150, which may cause environmental pollution due to scattering during oiling. Such excess grease removing members 180 and 180 'may be implemented in a knife shape and a comb-shape as shown, and in some cases, these two types of members may be used up and down.

In the drawings, reference numeral 160 denotes a chain guide for guiding the rotation of the chain 140, and 104 is formed in the lower portion of the main frame 100 to inevitably discharge water filled in the main frame 100 when cleaning water on the drawing. The water discharge hole for this is shown. Reference numeral 102a denotes a vertical hole for bolt through formed in the fastening bracket 102. Thus, by forming the bolt through hole as a vertical long hole, the height of the main frame 100, that is, the oil brush 150 of the You can adjust the height accordingly. For example, when the oiling brush 150 is worn, a constant amount may be always oiled by adjusting the height of the main frame 100 on the fastening bracket 102.

Reference numeral 190 denotes a tension control unit for adjusting the tension of the chain 140, this also allows the horizontal spherical 190a to adjust the position of the rotating shaft of the driven sprocket 130 to the left and right as a whole of the chain 140 Tension can be adjusted properly.

10 is an electrical block diagram of the wheel oiling system of the train of the present invention. As shown in Figure 10, the electrical configuration of the wheel oiling system of the train of the present invention is largely, the train passage detection unit 330, grease discharge pump 315 and grease discharge to drive the train passage detection unit for detecting whether the train passes. The grease discharge pump driver 310 and the chain drive motor driver according to signals input from the pump driver 310, the chain drive motor 325, the chain drive motor driver 320, and the train passage detector 330. And a controller 300 for controlling the operation of the controller 320.

In the above-described configuration, the train passage detector 330 may include an optical sensor as described above, and the installation position of the optical sensor may be appropriately determined in relation to the installation position of the oiling apparatus. The train pass detector 330 outputs a low level signal to the controller 300 while the train does not pass, and outputs a high level signal to the controller 300 while the train passes, or vice versa. do. The controller 300 may be implemented as a hardware or software device.

In addition, it is possible to set the idle time and the operating time so that the oil tanker does not operate by track members or other equipment vehicles passing the oil tanker installation point during the late-night hours when the operating train does not go. Can be.

Hereinafter, the operation of the wheel oiling system of the present invention will be described. First, when the heat shield and the detection unit 330 detects the entry of a train, the train detection signal is output to the control unit 300 until the train passes, and accordingly, the control unit 300 transmits to the chain drive motor driving unit 320. The chain 140 is rotated by driving the chain driving motor 325 by outputting a control signal. At the same time, the control unit 300 outputs a control signal to the grease discharge pump driver 310 to drive the grease discharge pump 315 so that the grease discharged from the grease discharge nozzle 170 is buried in the oil brush 150. At this time, the rotational speed of the oil brush 150, that is, the rotational speed and the driving time of the chain drive motor 325 may be appropriately adjusted to suit the site situation in consideration of the traveling speed of the train.

As such, while the train travels through the installation point of the oiling device, the oiling brush 150 continuously applies grease to the friction surface of the wheel 220 flange, and this operation is repeated until the train completely passes. Grease is applied to all the wheels from the leading wheel to the rear wheel.
