DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention
The present invention relates to a tong rail antifriction device that slides on a slide.

[0002]

2. Description of the Related Art As a friction reducing device for a tongue rail, Shokai Sho 5
7-137602 is known. A constant amount of oil is sprayed from the nozzle onto the slide surface each time the tongue rail reciprocates. This configuration unnecessarily increases oil consumption. When passing through the train, oil is raised and pollutes the environment. In the case of an elevated line in an urban area, the adverse effect is particularly large. It is desirable that an appropriate amount of fuel be automatically supplied only when necessary.

[0003]

The point of refueling is closely related to the weather. The need for refueling is greatest after the rain. When fine weather continues, refueling is intermittent. Rainfall, rainfall intensity,
Rain gauges are available on the market that can accurately measure the start and end points of the descent. Using this, an automatic device that refuels only when refueling is required is made.

[0004]

In FIG. 1, a branch rail B branches off from a main rail M, and a tongue rail T connected to the branch rail swings on the slide 1 around a connection point P. The two tongue rails T are connected by a connecting rod 2, and by reciprocation thereof, one of the tongue rails comes into contact with the main rail to release the slide surface. On the other hand, the other tongue rail closes the slide surface. In FIG. 2, the tong rail T indicates a solid line when the slide is open and a chain line when the slide is closed.

The oil tank 3 incorporates a hydraulic pump 4, has two discharge holes, and is provided with solenoid valves 3a and 3b, respectively. The solenoid valves 3a and 3b pass through a plurality of branch pipes to the end pipes 4a and 4b, respectively, to form a pair of pipe systems. The nozzle at the distal end of the terminal tube is mounted so as to jet to the open sliding surface as shown in FIG. 2, and the nozzle is provided with a spring-loaded low-pressure valve (not shown) so as to automatically close at low pressure.

The connecting rod 2 is provided with a limit switch 2a so as to be engageable, while the central control device 5 is provided with a pipe system selecting device 6. The device 6 is a limit switch 2a
To know the position of the tong rail, and 2
One of the two solenoid valves 3a and 3b can be selectively opened. The control device 5 is additionally provided with a weather determination device 7. The apparatus 7 incorporates a rain gauge and other weather determination tools. As described above, the rain gauge can detect the amount of rainfall, the end point of falling, and the like, and determines the refueling point after the rain. Upon receiving this signal, the control device 5 drives the hydraulic pump 4 and simultaneously opens one of the solenoid valves 3a and 3b. Due to the tires in the control device, the pump stops after a set time and the solenoid valve returns to the old one.

After the rainfall, another timer may be set in the control device 5 so that intermittent refueling can be performed at regular intervals in the case where fine weather continues. The device 5 also has a thermometer,
A heater 8 linked to this is provided in the oil tank 3 so that the viscosity of the oil does not change even in cold weather.

[0008]

[Effect] The hydraulic pump is driven only when refueling is required, and the nozzle refuels only one of the opened sides. Oil wasted,
It does not hurt the environment.
