DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lubricating oil for tong rails for automatically supplying lubricating oil to a sliding surface in order to reduce the sliding frictional resistance between the floor surface and the tong rail when the tong rail is converted. The present invention relates to an automatic feeding device.

[0002]

2. Description of the Related Art As a means for reducing the sliding frictional resistance between a tongue rail and a floor plate during a conversion operation of a rail tong rail and improving the conversion sliding property, a special lubricating oil is applied to a sliding surface. The method is general.

[0003] As a conventional lubrication operation, a method in which an operator carries a container containing lubricating oil and directly applies the lubricating oil to the floor plate with a brush or the like or an automatic lubrication method using a simple lubricating device is generally used. In the latter method, one end of the bundled fiber or band-like fiber is dropped into the oil tank, and the other end is brought into contact with the sliding surface of the tongue rail, and the lubricating oil sucked up by the capillary phenomenon is continuously dripped onto the floor plate. A refueling machine having a structure for supplying oil is used. In addition, refueling machines have been devised that use plane motion at the time of tong rail conversion as a power source, but are not widely used.

[0004]

The application of the lubricating oil by hand is inefficient, and the operation under the hot summer sun and the application operation in severe cold can be said to be a representative of the 3K operation. In addition, the lubricating oil application device applying the capillary phenomenon
This is a so-called run-off method, in which lubricating oil is continuously supplied to the floor plate regardless of the operation of the tong rail and day or night. Therefore, in most cases, the lubricating oil is excessive, leading to waste of lubricating oil. In addition, dirt and dust adhere to the lubricating oil on the excessively lubricated tong rail sliding surface, and the tongue rail sliding surface , And conversely, increase the frictional resistance.

The present invention solves all of the problems in the prior art described above, and automatically and reliably supplies a minimum required amount of lubricating oil to a sliding surface only when a tong rail is changed. It is an object to provide an automatic lubricating oil supply device for tong rails.

[0006]

SUMMARY OF THE INVENTION The present invention relates to an oil supply mechanism for supplying lubricating oil to reduce friction on a sliding surface of a tongue rail when the tongue rail moves on a floor plate at the time of conversion. The hydraulic pump for refueling includes a cylinder and a piston in the middle, and includes a piston rod protruding on both sides of the cylinder, and both ends of the piston rod are brought into contact with a tong rail. The above problem is solved by an automatic lubricating oil supply device for tong rails, characterized in that the hydraulic pump is driven in accordance with the operation when the tong rail is changed to supply oil.

Preferably, the oil tank for storing the lubricating oil for the hydraulic pump includes an oil level pressurizing means for constantly pressing the oil level at the same pressure, and the cylinder is made of a transparent material. The operation and the wear state of the piston are made visible.

[0008]

Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a view showing an installation state of a tongue rail automatic lubricating oil supply device according to the present invention and a piping system for supplying a line sliding portion. The apparatus includes a double-acting hydraulic pump 1 having piston rods 3 and 4 protruding on both sides of a cylinder 2, an oil tank 31 which is installed beside a track and is connected to the hydraulic pump 1, and a hydraulic pump 1 described later.
The lubricating oil sent out from the floor plate 6 fixed to the tongue rail sliding portion on the sleeper 5 and the hydraulic piping 8 for supplying the lubricating oil sent from the tongue rail 7 sliding thereon Be composed.

The hydraulic pump 1 is, as shown in FIG.
It has piston rods 3 and 4 projecting from both sides of the cylinder 2. The piston rods 3, 4 are one-piece,
It has a piston 11 and a piston ring in the middle,
Two compression chambers 12, 13 are formed in the cylinder 2 with the piston 11 and the piston ring interposed therebetween. The tip portions 3a, 4a of the piston rods 3, 4 are made of a hard insulating resin so as to be electrically insulated.

[0010] Both ends of the cylinder 2 are connected to oil inlet pipes 14, 1
End cover 1 provided with 4a and oil delivery pipes 15, 15a
The end covers 16, 17 and the piston rods 3, 4 are sealed via O-rings 18, 19.

The lubricating oil sent from an oil tank 31, which will be described later, through the hydraulic pipe 20 is split into two parts, each of which passes through a check valve 21, 22 and an oil inlet pipe 14, 14a.
, And from the oil discharge pipes 15 and 15a with the operation of the piston rods 3 and 4 described later, are sent to the oil supply sections of the tongue rails 7 through the check valves 23 and 24. . In that case, it is preferable that the hydraulic pipes 25 and 26 extending from the check valves 23 and 24 are branched, one of which is guided to the tongue rail 7 and the other is guided to the main rail 9. The tip of each of the hydraulic pipes 25 and 26 is held, for example, by passing through a through hole of a rail, and a nozzle for ejecting lubricating oil is attached to the tip. The hydraulic pipes 25 and 26 directed to the tongue rail 7 are flexible pipes.

The cylinder 2 can be made of reinforced plastic such as transparent polycarbonate or heat-resistant reinforced glass. If you do so, cylinder 2
It is possible to visually inspect the wear state of the piston 11 and the piston ring in the inside, the operating state of the piston rods 3 and 4, the state of the lubricating oil in the cylinder, and the like from the outside. However, in this case, it is preferable that the cylinder 2, that is, the hydraulic pump 1 be surrounded and protected by a strong cover in consideration of the possibility that the cylinder 2 may be damaged due to an abnormal external impact.

FIGS. 3 and 4 show examples of the structure of the cylinder cover of the hydraulic pump 1. FIG. The cover 28 is made of a thick iron plate and protects the cylinder 2 from external impact and pressure. An inspection port 29 is provided at the center of the cover 28 so that the inside can be inspected from outside.

FIG. 5 and FIG. 6 show a pressurized oil tank 31 for supplying lubricating oil to the hydraulic pump 1. Since the lubricating oil is viscous, there is a problem in supplying the oil from the oil tank 31 to the hydraulic pump 1 naturally. That is, if the hydraulic pump 1 self-inhales the high-viscosity lubricating oil, an excessive load is applied to the piston of the pump, and there is a risk that the switching work will be hindered.
In order to avoid such an obstacle, it is necessary to pressurize the lubricating oil delivered from the oil tank 31 to some extent when supplying the lubricating oil. In addition, the lubricating oil needs to be pressurized so that the lubricating oil is always delivered at a constant pressure regardless of whether the oil storage amount is full or close to zero.

Therefore, in the oil tank 31 used in the present invention, a method is used in which the lubricating oil 33 in the container 32 is constantly pressurized by a heavy metal upper cover 34 at a constant pressure. For this pressure adjustment, a pair of balance weights 35 for pressure adjustment are suspended symmetrically from the upper lid 34 via a sprocket 37 by a chain 36 outside the container 32.

A pressure weight 38 is attached to the chain 36. As the oil level decreases as the lubricating oil 33 is consumed, the pressure weight 38 descends into the container 32 and is consumed. The upper lid 34 is configured to have a weight corresponding to the weight of the lubricating oil 33. For this reason, even if the amount of the lubricating oil 33 decreases, the pressure supplied to the hydraulic pump 1 is always kept constant, and the piston 11 of the hydraulic pump 1
There is no extra burden on the user. When supplying the lubricating oil 33 into the container 32, the air vent valve 39 is opened, and the upper portion is opened by lifting the hook fitting 40 with the rope of the simple winder.

In the apparatus according to the present invention, the hydraulic pump 1 is fixed on an optional sleeper 5 or a track bed of the tong rail 7, and the oil tank 31 is placed in a place near the railroad where there is no hindrance to train operation and maintenance. Hydraulic piping 8 that is installed and exits from hydraulic pump 1
The installation is completed by disposing the nozzles at each end of the branch so as to face the tongue rail sliding surface of the floor plate 6.

In the present apparatus, the piston 11 of the hydraulic pump 1 is operated by utilizing the amount of lateral movement of the tong rail 7 from left to right and from right to left during a switching operation. That is, when the tongue rail 7 moves to the left in FIG. 2, the piston rods 3 and 4 also move to the left by being pushed by the tongue rail 7, and the lubricating oil in the left compression chamber 12 is pushed out by the piston 11. Oil delivery pipe 1
5 through the check valve 23, from the hydraulic pipe 25 through the hydraulic pipe fixed to the side of the tong rail 7,
A fixed amount of lubricating oil is jetted onto the sliding surface between the upper predetermined tongue rail 7 and the floor plate 6. Further, by arranging the hydraulic piping using the side surface of the main line rail 9, it is possible to apply the lubricating oil to the entire sliding surface of the tongue rail 7 and the floor plate 6.

As described above, the piston rods 3 and 4 are
In the case of moving to the left, the lubricating oil is supplied into the right compression chamber 13 via the check valve 22. Next, when the tongue rail 7 moves in the opposite direction, the respective parts operate in the opposite manner to the above, and oil is discharged from the compression chamber 13 side and the hydraulic piping 26
Lubrication is performed from the side, and lubricating oil is supplied to the compression chamber 12.

Such an operation is repeated every time the tong rail 7 is turned, and the sliding surface of the tong rail 7 and the floor plate 6 is reliably operated by the operation of the hydraulic pump 1 even when the turning direction is left or right. It is possible to constantly supply and apply a constant amount of lubricating oil.

As described above, in the oil tank 31 for supplying the lubricating oil to the hydraulic pump 1, the upper lid 34 functions as a hydraulic piston in the container 32, and when the lubricating oil in the tank decreases, the reduced lubricating oil A considerable amount of weight is transferred to the upper lid 34 together with the weight 35 mounted on the chain 36 via sprockets 37 mounted symmetrically at two places in the tank.
Since the upper pressure is applied, the initially set pressure can be maintained up to the check valves 21 and 22 of the hydraulic pump 1 via the lubricating oil pressure pipe 20 regardless of the increase or decrease of the lubricating oil.

When lubricating oil runs out and is replenished,
The air release valve 39 is opened, and the hook of the simple type hand-winding machine is hooked on the hook fitting 40 attached to the upper lid 34, and is wound up to a predetermined position. At the same time, the weight 35 attached to the upper lid 34 also returns to the original position via the sprocket 37. Then, the replenishing operation is completed by replenishing the lubricating oil and closing the replenishing port and the air vent valve 39. In the winter, a heater for keeping heat using the power of the solar cell is wound around the oil tank 31 to heat it.
Oil viscosity can be improved by lowering the viscosity of the lubricating oil.

[0023]

As described above, the hydraulic pump type lubricating oil supply system according to the present invention does not rely on an external power source.
There is an effect that an optimal amount of lubricating oil can be automatically supplied to the sliding surface between the tongue rail and the floor plate when necessary by utilizing a small force when the tongue rail is operated. Further, according to the present invention, it is possible to reduce labor costs for lubricating oil supply of tong rails and prevent waste of lubricating oil, and to supply a necessary amount of lubricating oil when necessary and to reduce cost. Economic effects can be expected by contributing.
