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 A special lubricating oil is applied to a sliding surface as a means for reducing the sliding frictional resistance between a tong rail and a floor plate and improving the sliding property during the conversion operation of a rail tong rail. 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 planar 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-down system, 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 lubrication oil is excessive, leading to waste of lubricating oil. In addition, dirt and dust adhere to the lubricating oil on the excessively lubricated tongue 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 provides an oil supply mechanism for supplying lubricating oil to reduce friction of a sliding surface of a tongue rail when the tongue rail moves on a floor plate at the time of conversion. In the hydraulic pump for refueling, a pinion fixed to a pivot shaft is formed on a side surface of an intermediate portion of a rod whose both ends are in contact with a tong rail and supported so as to be movable in the length direction of the sleeper. The above problem is solved by an automatic lubricating oil supply device for tong rails, wherein the lubrication oil is supplied by being driven by the operation of the rod when the tongue rail is converted by meshing with the rack.

Preferably, the lubricating oil supply oil tank for the hydraulic pump includes oil level pressurizing means for constantly pressurizing the oil level at the same pressure. Install an auxiliary tank to reduce the hydraulic resistance in the piping.

[0008]

Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a plan view showing an installation state of an automatic lubricating oil supply device for tong rails according to the present invention and a piping system for supplying a line sliding portion, and FIG. 2 is a detailed perspective view thereof.

In FIG. 1, reference numeral 1 denotes a rod having a rack 2 formed on a side surface of an intermediate portion.
The sleeper 6 is mounted on the intermediate sleeper 6 so as to be movable in the length direction thereof. Hard insulating resin caps 7, 7a are fitted to both ends of the rod 1. The length of the rod 1 is set such that the caps 7 and 7a lightly contact the inner surface of the tongue rail 5.

Reference numeral 8 denotes a hydraulic pump, on which a pinion 9 meshing with the rack 2 is fixed. Therefore, the hydraulic pump 8 operates by the pinion 9 being rotationally driven with the movement of the rod 1 described later. As the hydraulic pump 8, various types such as a gear pump, a vane pump, and a plunger pump can be used. A pressure pipe 11 extending from a pressurized oil tank 10 installed near the line is connected to a suction port of the hydraulic pump 8, and an oil discharge pipe 12 is connected to a discharge port.

FIG. 4 shows a configuration example of a pressurized oil tank 10 for supplying lubricating oil to the hydraulic pump 8. Due to the high viscosity of the lubricating oil, there is a problem in naturally supplying the oil pump 10 from the oil tank 10 to the hydraulic pump 8, and there is a risk of hindering the switching work. In order to avoid such a danger, it is necessary to pressurize the lubricating oil delivered from the oil tank 10 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, as the oil tank 10 used in the present invention, for example, a system in which the lubricating oil 33 in the container 32 is constantly pressurized at a constant pressure by the heavy metal upper lid 34 is used. A pair of pressure adjusting balance weights 35 is provided outside the container 32 for this pressure adjustment.
Symmetrically, the chain 36 hangs down from the upper lid 34 via a sprocket 37.

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 falls 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 is reduced, the pressure supplied to the hydraulic pump 8 is always kept constant, and the hydraulic pump 8 is not unnecessarily burdened.

Although such a pressurized oil tank 10 is installed and supplied to the hydraulic pump 8, a large resistance is still required to supply high-viscosity lubricating oil to the hydraulic pump 8 several meters away. There is a possibility that the suction by the hydraulic pump 8 may be hindered. Therefore, in the present invention, in order to avoid such a situation, the hydraulic pump 8 is further provided with a suction port side.
30cc to 100c to reduce hydraulic resistance in piping
c, and an auxiliary tank 13 having a capacity of about
To reduce the load.

The oil discharge pipe 12 is divided into two parts, each of which is connected to a nozzle pipe 14 extending along the inner surface of the tongue rail 5. Usually, the vicinity of the tongue rail 5 of the oil delivery pipe 12 is a flexible tube 12a. Nozzle piping 1
4 is provided with a nozzle 16 for supplying lubricating oil toward a floor plate 15 fixed on the sleeper 6.

As the nozzle 16, it is preferable to use a nozzle filled with an oil absorbing material 17 containing lubricating oil (see FIG. 3). In this case, the lubricating oil is absorbed by the oil-absorbing material 17 and is leached only when the hydraulic pump 8 is operated and a certain pressure is applied. Therefore, oil leakage when the hydraulic pump 8 is stopped is prevented.

Nozzle pipe 14 installed on tong rail 5
May be provided only on the inner side surface of the tongue rail 5, or may be provided on both the inner and outer side surfaces by extending through the side surface (see FIG. 5). As means for fixing the nozzle pipe 14 to the tongue rail 5, it is conceivable to use a permanent magnet and an adhesive together.

That is, the support base 1 made of a permanent magnet whose lower surface is inclined corresponding to the lower inclined surface 18 of the tong rail 5.
9 is adhered to the lower inclined surface 18 via an adhesive. Thus, the support base 19 is firmly fixed to the tong rail 5 by the adhesive force of the adhesive and the attractive force of the magnet. The nozzle pipe 14 is held by a saddle 20, and the saddle 20 is supported by being screwed to a support base 19.

In the apparatus according to the present invention, the rod 1 and the hydraulic pump 8 are installed on an optional sleeper 6 or a track bed of the tongue rail 5, and the oil tank 10 is used to obstruct the operation and maintenance of the train near the track. The nozzle pipe 14 connected to the oil discharge pipe 12 coming out of the hydraulic pump 8 is installed in such a manner that the nozzle 16 faces the tongue rail sliding surface of the floor plate 15 by the above method. Completed.

In the present apparatus, the hydraulic pump 8 is driven to perform refueling by utilizing the amount of lateral movement of the tong rail 5 from left to right and from right to left during a switching operation. That is, when the tong rail 5 moves rightward or leftward, the rod 1 is pushed by the tong rail 5 and moves in the same direction, and each time the pinion 9 meshing with the rack 2 is rotated. As a result, the hydraulic pump 8 operates to perform a discharge operation to the oil discharge pipe 12.

Such an operation is repeated every time the tong rail 5 is turned, and the sliding surface of the tongue rail 5 and the floor plate 15 is reliably operated by the operation of the hydraulic pump 8 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 10 for supplying the lubricating oil to the hydraulic pump 8, when the upper lid 34 functions as a hydraulic piston in the container 32 and the lubricating oil in the tank decreases, the reduced lubricating oil A significant amount of weight, along with a weight 35 attached to a chain 36, via a sprocket 37 symmetrically attached to two places in the tank,
Since it is applied above, it becomes possible to continue to supply the lubricating oil to the hydraulic pump 8 at the initially set pressure regardless of the increase or decrease 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.

According to the third aspect of the present invention, there is an effect that the hydraulic resistance in the pipe is reduced and the load at the time of suction of the hydraulic pump is reduced.
