Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a point oil supply device capable of automatically supplying oil to a railway point.

[Prior Art] The point of railways is to allow vehicles to be interchanged between a pair of reference rails that form a reference line and a pair of branch rails that form a branch line, as shown in, for example, Japanese Patent Laid-Open No. 64-58701. The vehicle is replaced by opening and closing the tongue rail. The tongue rail is opened and closed by swinging by a motor or manually around one end side in the longitudinal direction, and is slidable on a floor plate supporting the rail in the swinging state.

By the way, in order to smoothly open and close the tongue rail, the point was to refuel between the ton gray rail and the floor plate supporting the tongue rail. Refueling is performed several times a month or once a week, and is generally performed along with track maintenance work in the hours when trains do not pass often such as midnight. The refueling work was carried out by a group of three, one person monitoring the train, one removing dirt on the floor board with a waste cloth, and the other one painting the oil (lubricating oil) on the floor board with a brush. .

However, performing refueling work by hand is extremely heavy work, and therefore, the applicant of the present invention has been using the conventional method.
And the point lubrication device shown in Japanese Utility Model Publication No. Sho 63-63103 were proposed. That is, this device includes an oil supply source for storing oil, an oil supply pipe arranged along the longitudinal direction of the tongue rail, a pump for supplying oil from the oil supply source, and pumping the oil to the oil supply pipe at predetermined intervals. A discharge nozzle provided in the oil supply pipe and capable of discharging the oil pumped by the pump between each floor plate and the tongue rail.

According to this device, since the oil is discharged from the discharge nozzles arranged between the floor plates and the tongue rails every predetermined time, the three workers do not apply oil to the floor plates as described above, and the labor is reduced. The cost and point management cost can be significantly reduced.

[Problems to be solved by the invention] By the way, the points are regularly disassembled and inspected, and repairs are performed in some cases due to safety management requests. Along with this, the point oil supply device installed at the point was also removed from the point portion and reattached to the point along with reassembly of the point. The point is that it is generally assumed that the installation position of each floor plate and the distance between the floor plates in the longitudinal direction of the tongue rail in the state after reassembly is significantly different from that before the disassembly. For this reason, there is a case where a displacement occurs between the discharge nozzles arranged at a predetermined interval in the oil supply pipe of the point oil supply device installed again and the corresponding floor plate. In such a case, conventionally, if oil was supplied onto a large number of corresponding floor plates, there was no particular problem, and the discharge nozzle was displaced, and some floor plates to which oil was not supplied were ignored. However, if this condition is left as it is, some floor plates may cause rust on the upper surface.
It was a problem from the point of view of management.

On the other hand, in the conventional point oil supply device, intermittent drive of the pump (drive at predetermined time intervals) is performed by a continuously rotating motor and a cam mechanism connected to the motor and intermittently operating the pump. Was there. Therefore, the motor is constantly rotating, and power is wasted accordingly. Therefore, it has been desired to develop a pump that consumes less power and is easy to manage.

A first aspect of the present invention is to provide a point oiling device that can easily deal with various kinds of points and disassembly and inspection, which can easily cope with the arrangement state and arrangement interval of floor plates. Has an aim.

A second object of the present invention is to provide a point refueling device that is easy to manage and can significantly reduce power consumption.

[Means for Solving the Problems] In the first aspect of the present invention, in order to achieve the above-mentioned object, the position of each discharge nozzle is arranged along the longitudinal direction of the tongue rail corresponding to each floor plate position. It is adjustable.

A second aspect of the present invention is, in order to achieve the above object, a pump, which is driven by a solar cell to perform a timekeeping operation, and which generates a pump drive signal at predetermined time intervals, and A pump drive circuit that inputs a pump drive signal generated by the drive signal generation unit and issues a drive command for the pump is provided.

[Operation] According to the first aspect of the present invention, the position of each discharge nozzle disposed in the oil supply pipe can be adjusted along the longitudinal direction of the tongue rail in correspondence with each floor plate position. It is possible to install point lubrication devices at points having various floor plate intervals and perform automatic oil supply to each floor plate. In addition, the point is disassembled and inspected, and even if the space between each floor plate and the installation position of the floor plate are different from those before the inspection, the position of each discharge nozzle is adjusted according to the position of the floor plate,
Can respond. As a result, it becomes possible to provide various types of points and a point oil supply device that can easily deal with overhaul and inspection.

According to a second aspect of the present invention, a pump is driven by a solar cell to perform a timekeeping operation, and a drive signal generator that generates a pump drive signal at predetermined time intervals, and the drive signal generator. And a pump drive circuit that inputs a pump drive signal to generate a pump drive command. That is, the drive signal generator is
It is operated by a solar cell that does not require any electric power equipment and generates a pump drive signal at predetermined time intervals. Further, the pump drive circuit receives the pump drive signal and issues a drive command for the pump, and does not drive the pump (for example, drive the motor or the like) in other time zones, thus reducing power consumption accordingly. It becomes possible to do. Therefore, the cost required for management can be significantly reduced, and the power consumption for operating the pump can be significantly reduced.

The tip ends of the pair of tongue rails 16 sliding in the direction of the arrow Y on the floor plate 19 arranged along the rail longitudinal direction face the inner surface of the corresponding main rail 10 (see FIGS. 1 and 2).
See figure). That is, the tip end portion of the tongue rail 16 can move in and out of contact with the main rail 10.
Oil (lubricating oil) is automatically supplied by the point oil supply device 26 between 16 and each floor plate 19 supporting the same.

Point The lubricator 26 is roughly divided into the pump unit 2
7, a distribution unit 28, and a refueling unit 29. The pump unit 27 is arranged on the side of the track A as shown in FIG. 1, and the unit 27 and the distribution unit 28 are connected by an oil feed pipe 30. The distribution unit 28 is arranged between the base end sides of the pair of tongue rails 16. At the inner side surface position of each tongue rail 16, a long oil supply unit 29 is supported and fixed along the longitudinal direction of the rail. Each refueling unit 29 is connected to each distribution unit 28.
That is, the oil supplied from the pump unit 27 through the oil supply pipe 30 is distributed to the left and right by the distribution unit 28 and supplied to the left and right oil supply units 29.

The pump unit 27 is always covered with a protective cover 31 so as to protect the entire pump unit 27 from rainwater and the like. As shown in FIG. 8, the pump unit 27 includes a storage tank 32 (fuel supply source), a pump drive motor 33, and a pump body.
34, feed button 35, power switch 36, time switch 37 and the like. Oil can be stored in the storage tank 32, and an oil level gauge 38 for visually recognizing the internal oil level is formed on the outer surface of the tank 32. The motor 33 is operated by the ON operation of the power switch 36, and the pump body 34 can be operated by the continuous drive of the motor 33 as in the conventional point oil supply device.

The pump body 34 is located above the tank 32 as shown in FIG. The pump body 34 includes a reduction gear group 40 on the output shaft 39 side of the motor 33. Worm gear on output shaft 39
41 is pivotally supported and meshes with the gears of the reduction gear group 40. The reduction gear group 40 is provided with a cam 42 that receives the drive transmission of the motor 33 and rotates once per hour. An arm 43 which is swingable in the E direction around the support shaft D is brought into contact with the cam surface of the cam 42.
The arm 43 follows the rotation of the cam 42, and once every hour, the arrow E
Rocks in the direction. A hammer portion 44 is provided below the tip of the arm 43.
Is provided, and the hammer portion 44 can contact the upper end portion of the flanger shaft 45. The flanger shaft 45 can be moved up and down in the cylinder cylinder 46, and the flanger shaft 45 is always operated by the elastic force of the tension spring 47 and the compression spring 48 which are mounted on the shaft.
The cylinder 46 is positioned at a fixed position (except when the rocking of 43 is performed).

As shown in FIG. 9, the feed button 35 is located at the upper end portion of the elevating shaft 49, and the elevating shaft 49 is inserted into the support tubular portion 50 and can be moved up and down. This elevating shaft 49 has a feed button 35
Positioning the scales at the scales 1, 2, 3 (see FIG. 10) makes it possible to position the elevating shaft 49 at each of the upper and lower positions within the support tubular portion 50.
It is performed by fixing the feed button 35 with. By thus raising and lowering the feed button 35 and positioning it at each position, the lower end position of the raising and lowering shaft 49 is also variably set up and down. The lower end of the elevating shaft 49 is located above the hammer portion 44 of the arm 43, and the lower end regulates the upper swing end of the arm 43 swinging in the direction of arrow E once an hour. There is. That is, the arm 43, which swings once per hour by the rotation of the cam 42, interferes with the lower end of the lift shaft 49 that is raised and lowered and positioned by adjusting the feed button 35, and the upper swing end of the arm 43 can be set. I am trying.

The arm 43 swings once per hour due to the rotation of the cam 42, so that the hammer portion 44 of the arm 43 moves the flanger shaft 45.
As a result, the flanger shaft 45 moves downward in the cylinder 46 against the elastic force of the tension spring 47. A cylinder chamber 52 is defined below the flanger shaft 45 in the cylinder cylinder 46. Below the cylinder chamber 52 is a suction port communicating with the inside of the tank 32.
53 is formed, and a filter 54 is attached to the suction port 53. Further, a first check valve 55 is provided in a pipe line that connects the suction port 53 and the cylinder chamber 52. Cylinder chamber
A discharge pipe 56 is connected to 52, and a connection port 57 is formed on the outlet side of the discharge pipe 56. A second check valve 58 is provided at this connection port 57. When the upper end of the flanger shaft 45 is hit from above by the hammer portion 44 of the arm 43 and the flanger shaft 45 moves downward, the shaft 45
As a result, the inside of the cylinder chamber 52 is compressed, and the oil sucked into the cylinder chamber 52 is pumped to the discharge pipe line 56 side. The oil to be pumped is discharged from the connection port 57 via the second check valve 58. The flanger shaft 45 moved downward by the swing of the arm 43 is restored to its original vertical position by the elastic force of the tension spring 47 mounted on the shaft 45, and moves upward. As a result, the oil in the tank 32 flows into the cylinder chamber 52 from the suction port 53, and the inflowing oil is prevented from flowing back to the tank 32 side by the action of the first check valve 55.

In this way, the pump body 27 can pump the oil in the tank 32 to the connection port 57 side once an hour by the continuous rotation of the motor 33. Further, the amount of oil pumped at one time can be adjusted by raising and lowering and positioning the feed button 35. That is, by adjusting the feed button 35 up and down, the up-and-down shaft 49 is adjusted in the up-and-down position.
The swing amplitude of the arm 43 that interferes with the lower end of the 49 is adjusted, and the amount of oil pumped at one time is adjusted. By the way, in Fig. 10, the scales 1, 2, and 3 relate to the amount of oil pumped at one time, and the unit is cc. In FIG. 9, reference numeral 59 relates to an oil receiving bucket and is adapted to constantly supply a constant amount of oil to the reduction gear group regardless of the oil surface position in the tank. The time switch 37 shown in FIG. 8 relates to a device that regulates the drive time of the motor 33 in a day, and by turning on the time switch 37 and inputting and setting the motor rest time period beforehand, for example, midnight It is possible to set a time period in which the motor 33 is stopped from being energized, such as hour to 5:00 am.

The refueling unit 29 is supported on the tongue rail 16 at the center in the longitudinal direction by a fixing member 64 having a U-shaped cross section. That is, as shown in FIG. 5, with the support member 62 and the base of the rail 16 sandwiched between the fixing metal fittings 64, the tightening bolts 65 previously screwed into the fixing metal fittings 64 are screwed in the tightening direction. As a result, the center portion of the oil supply unit 29 is supported by the rail 16. Further, the tip end side of the oil supply unit 29 (specifically, the metal fitting 66 welded to the support member 62) is also fixed to the rail 16 by screwing a fixing bolt 67 and a nut 68 which penetrate the rail 16 ( (See Figures 3 and 4).

The bottom portion of the tongue rail 16 is hung down and dropped on the corresponding floor plate 19 in the arrow F direction. Similarly, the discharge nozzle 78 formed at the tip of the pipe material 79 also discharges oil in the direction of arrow F between the floor plate 19 and the rail 16 located on the most distal side of the tongue rail 16. In this way, once the oil is supplied to the corresponding floor plate 19 once an hour, the opening / closing operation (idling) in the θ direction of the point is performed as necessary, and the tongue rail 16 and the floor plate supporting this are performed. The oil should be evenly distributed between 19 and.

Next, the operation of the point oil supply device 26 according to the above embodiment will be described. According to the present device 26, the pump body 34 is operated by the drive of the motor 33, and the oil in the tank 32 is supplied to the oil pipe 30 → distribution unit 28 → oil supply unit 29 at intervals of once an hour.

Is always charged with sufficient electric power to operate the circuits shown in FIG.

The drive signal generation unit 91, as shown in FIG.
It is composed of a signal generation circuit 96 and a timing setting circuit 97. The clock circuit 95 is composed of a clock circuit, a clock circuit or the like, and can output time information to the signal generation circuit 96. The signal generation circuit 96 inputs the time information and enables the pump drive signal to be transmitted in the state where the preset time information is input. The timing setting circuit 97 determines the transmission timing of the pump drive signal transmitted by the signal generation circuit 96 (eg, every hour,

It is possible to move 103 back and forth. When power is supplied to the solenoid 101, the rod 103 moves forward (moves downward), contacts the upper end of the flanger shaft 45, and pushes the shaft 45 downward. As a result, the oil in the cylinder chamber 52 is pumped to the oil supply unit 29 side. When the input of the pump drive signal to the signal input unit 98 is released, the relay 100 is also turned off and the rod 103 of the solenoid 101 is also moved backward. As a result, the pumping of the oil to the oil supply unit 29 side is completed, and the tank 32 is newly placed in the cylinder chamber 52.
The oil inside will be replenished. The solenoid 101
Can be moved up and down by adjusting the screw of the adjusting screw 104. That is, the solenoid 101 can adjust the forward end of the rod 103 by adjusting the position vertically.
As a result, the vertical movement amplitude of the flanger shaft 45 is also adjusted, and the amount of oil pumped by the pump body 102 can also be adjusted. Other configurations and operations are similar to those of the pump main body 34 shown in FIG.

According to the pump main body 102 and the drive circuit thereof according to the present embodiment, the solar cell 90 is installed on the side of the track A of the line,
By the electromotive force of 90, the clock circuit 95 of the drive signal generation unit 91, the signal generation circuit 96, the timing setting circuit 97, the signal input unit 98 of the pump drive circuit 92, and the relay 100 can be operated. Therefore, the pump body 102 can be automatically controlled without requiring extra power supply equipment and management cost. Further, in the pump main body 102, the solenoid 101 is energized only when the pump drive signal is transmitted, and the motor 33 is always driven by the motor 33 like the pump main body 34 shown in FIG.
Since no electric power is consumed to drive the power source, the power consumption can be reduced accordingly.
