BACKGROUND OF THE INVENTION
The present invention relates to an automatic branching unit oil supply device that automatically supplies oil to a branching unit of a railway.
[0002]
[Prior art]
As shown in FIG. 8, the railway branching device is provided with a pair of tongrel 51 at the tip of the lead rail 50, and the point switching is performed by moving the tongrel 51 with a rolling rod (not shown). . At this time, the tongrel 51 slides on the floor board 53 disposed on the sleepers 52. However, if the sliding resistance increases due to rust, dust or the like, the point switching may not be performed smoothly.
[0003]
In order to eliminate this problem, the branching device has been regularly cleaned and refueled by human hands. However, since this work is in-track work and is dangerous, attempts have been made to eliminate the need for refueling by making the floorboard made of ceramic, embedding Teflon or carbon, or made of oil-impregnated metal. However, even if such a device is added, refueling cannot be completely eliminated, and there remains a problem that adhesion of dust or the like cannot be prevented.
[0004]
Therefore, the present applicants first developed an automatic branching oil supply apparatus in which a nozzle and an oil supply pipe are attached to a Tongrel and oil is dropped from the nozzle onto the floor plate at regular time intervals. It has been published as a special issue. As shown in FIG. 8, this branching device automatic oil supply apparatus is configured such that a metal duct 54 is attached to the side surface of a Tongrel 51 and an oil supply pipe 55 and a nozzle 56 are arranged on the inside thereof. However, this device has been found to have the following problems.
[0005]
{Circle around (1)} Since the metal duct 54 is heavy, it is necessary to attach it to the side surface of the Tongrel 51 using the bolts of the branching device main body, which takes a lot of time.
(2) Since the metal duct 54 is long, it is difficult to handle during transportation and installation. Moreover, the transportation to the site was a chartered transportation, which required a lot of costs.
(3) Since the shape and structure of the turnouts are not the same, it was necessary to conduct on-site surveys before production, including the layout of floorboards, and to produce them individually.
[0006]
[Problems to be solved by the invention]
The present invention solves the above-mentioned conventional problems, can be easily attached to various branching devices, can be transported to the field at low cost, and reliably drops oil on the floor plate of the branching device. It is made in order to provide the branching device automatic oil supply apparatus which can do.
[0007]
[Means for Solving the Problems]
In order to solve the above-described problems, the automatic branching device oil supply apparatus of the present invention drops a main oil supply pipe, an oil distributor, and an oil which has been divided onto a protective pipe having a predetermined length onto a floor plate of the branching apparatus. A unit that can be attached to the inside of the tongler of the branching unit by incorporating a nozzle to be connected, and by connecting the end of the protective tube of each unit with a cover, each unit is adjusted in the longitudinal direction of the tongler It is characterized by being free . In addition, it is preferable to connect a unit having a protective tube of a predetermined length by a slidable cover, and each part is made of resin, and the end of the oil supply main pipe of each unit can be connected by a one-touch type main pipe joint It is preferable to do so.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a plan view of a branching device to which the branching device automatic refueling device of the present invention is attached. In the same manner as in the prior art, 51 is a Tongler, 52 is a sleeper, and 53 is a floor board arranged on each sleeper 52. . The tongue rail 51 is driven by a rolling rod 57 and slides on the floor plate 53 to switch points.
[0009]
A large number of oil supply units 1 as shown in FIG. Each unit 1 preferably has a structure in which an oil supply main pipe 3 made of resin such as Teflon is passed through a protective pipe 2 made of hard resin having a predetermined length (for example, about 1 m). A slit 4 is formed on the upper surface of the protective tube 2 except for the central portion. Moreover, the main pipe joint 5 which can be connected by one touch only by inserting the end part of the oil supply main pipe 3 of the adjacent unit 1 is formed in the end part of the oil supply main pipe 3.
[0010]
As shown in the enlarged view of FIG. 3, an oil distributor 6 is attached to the central portion of the protective tube 2. The oil distributor 6 is an instrument that distributes oil flowing through the oil supply main pipe 3 to the two nozzles 7 and 7 provided in each unit 1 while adjusting the flow rate. These nozzles 7 are also made of a resin such as Teflon, and the base portion thereof is connected to the oil distributor 6 by the nozzle pipe joint 8, and the tip thereof is formed from a hole formed at a constant interval on the side surface of the protective tube 2. And is placed on floor plates 53 and 53 on both sides of the oil distributor 6. The central portion of the protective tube 2 is covered with a metal cover 9.
[0011]
Such a unit 1 is attached to the inner side of the Tongrel 51 by means of a mounting bracket 10. FIG. 4 is a cross-sectional view showing this attachment state. The mounting bracket 10 is formed by bending a steel plate having excellent spring properties into a J shape, and its main body portion is fixed between the protective tube 2 and the oil distributor 6 by bolts 11. Then, the unit 1 is fixed to the inner side of the Tongrel 51 by fixing the lower end with the fixing screw 12 in a state where the lower end bites into the bottom rear surface of the Tongrel 51. Since the unit 1 of the present invention is lighter than the conventional product, it is not necessary to attach it using the bolt of the branching device as in the conventional case.
[0012]
The unit 1 is configured to have a fixed length, but as described above, the size of the branching device is various. For this reason, it is inevitable that a gap is generated between the units 1 and 1. In view of this, the present invention employs a structure in which the end portions of the protective tube 2 of each unit 1 are connected to each other by a slidable cover 13 or the like. The cover 13 is also formed by forming a slit in the resin tube, and the gap between the units 1 and 1 is connected by covering the upper surface of the protective tube 2. In addition, since a heater for melting snow may be installed in the branching device, it is preferable to further cover the oil supply main pipe 3 and the like by covering the outside of the cover 13 with a nonflammable cover 14.
[0013]
As described above, by attaching a large number of units 1 inside the tongrel 51 and inserting the end of the oil supply main pipe 3 of the unit 1 adjacent to the main pipe joint 5 at the end of the oil supply main pipe 3 of each unit 1, A continuous piping path as shown in FIG. 6 is formed. Reference numeral 15 denotes a distribution box, and oil is supplied at regular time intervals from an oil supply pump installed on the side of the branching unit. Further, a tip nozzle 16 having a special shape as shown in FIG. 7 is attached to the tip of the Tongrel 51 so that oil can be supplied onto the floor plate 53 at the tip. The tip nozzle 16 is fixed to the connecting plates 58 at both ends of the rolling rod 57. The oil supplied through such a piping path is sent to the nozzle 7 while being controlled in flow rate by the oil distributor 6 of each unit 1 and dropped on the floor plate 53 at regular time intervals to form an oil film, thereby reducing the sliding resistance. It can be reduced and dust can be washed away.
[0014]
【The invention's effect】
Since the automatic branching device refueling apparatus of the present invention is configured as described above, the unit 1 is sent to the site by inexpensive transportation means such as courier, and the mounting bracket 10 is used on the site to the Tongleil 51 simply. Can be installed. In addition, since the gap between the units 1 and 1 can be easily connected by the slidable cover 13, there is no need for a prior investigation or the like, and there is an advantage that the manufacturing cost can be greatly reduced as compared with the conventional one-piece production. is there. Furthermore, if the one-touch type main pipe joint 5 is provided at the end of the oil supply main pipe 3 of each unit 1, there is an advantage that the construction at the site is further simplified. Therefore, this invention is a high value as a branching device automatic oil supply apparatus which solved the conventional problem.
