Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a section slider support metal fitting, and in particular, even if the inclination of the section and the inclination of the pantograph when entering the section are largely different, the pantograph smoothly moves from the trolley wire without separating. The present invention relates to a section slider support metal fitting that suppresses arc generation.

[0002]

2. Description of the Related Art Conventionally, a section insulator which is generally used as a sorting device includes a trolley wire mounting bracket that directly grips a trolley wire, an insulator that electrically separates the front and rear of a section, and a conductor that is arranged on the insulator. It is composed of sliders attached together, and is arranged in a straight line between the end portions of the trolley wire via the insulator of the section.Sliders are placed slightly higher than the height position of the trolley wire on both sides of this connecting trolley wire. The two sliders and the insulator are integrally attached by a slider support fitting.
Further, the slider support metal fitting engages with the slider rigidly.

[0003]

In the conventional type section described above, when the pantograph slides on the slider and moves to the outlet side trolley wire (main line), the pantograph is largely separated. The derailment tends to increase as the train speed increases, and is also easy to derail when the pantograph inclines into a section. This is because the conventional slider has high rigidity, so that the follow-up characteristic of the pantograph gradually decreases as the train speed increases, and the pantograph cannot be smoothly moved between the slider and the outlet-side trolley wire to depart. Especially in the latter case where the inclination of the section itself and the inclination of the pantograph when entering the section are greatly different, the pantograph shifts from the slider to the main line on the exit side of the section, There is a problem in that an arc is generated due to a large separation line. Therefore, the present invention adopts a structure in which the slider is supported on the outlet side from a fixed type as in the prior art, and has a structure in which a certain amount of movement is provided in the pushing-up direction. An object of the present invention is to provide a section slider support metal fitting that solves the problems of the support metal fittings, prevents the pantograph from separating, and suppresses arcing.

[0004]

In order to achieve the above object, the section slider support metal fitting of the present invention, in a section arranged between connecting trolley wires, is provided with an insulating rod arranged between the trolley wires. The slider support metal fitting is arranged so as to sandwich the slider between the slider and the insulating rod, and the slider is mounted on the lower end of the shaft supported by the slider mounting metal fitting body located at the tip of this slider support metal under spring pressure. Attach the ear piece to be sandwiched,
It is characterized in that the slider can be pushed up and supported by a pantograph against the spring pressure when passing a train.

In the section slider support fitting of the present invention having the above structure, even if the pantograph of the train entering the section is inclined, the slider supported by the slider support fitting is pushed up by the inclination of the pantograph. The pantograph passes through the insulating rod section in contact with both the slider and the insulating rod at the same level as the trolley wire of the main line, and the trolley line of the main line and the pantograph do not separate even at the section exit immediately after passing through this section. Can be held, and the occurrence of an arc due to a disconnection can be prevented in advance.

In this case, a piston retainer, a spring, and a cap, which are made of highly lubricious and highly durable material, are fitted in the body of the slider support metal fitting, and the piston retainer, the spring, and the cap are passed through. It is possible to insert a shaft and to provide a piston ring made of a material with excellent lubricity and durability on the outer circumference of the cap.

In the section slider support fitting of the present invention having the above-mentioned structure, when the slider is pushed up by the pantograph and the spring is compressed, the cap fitted with the piston ring is supported so that the cap moves smoothly in the vertical direction. Since it is possible to prevent unnecessary tilting of the shaft with respect to the front, rear, left and right, it is possible to smoothly move even when pushing up the slider by a tilted pantograph or the like, and it is possible to prevent the pantograph from separating even when the train speed is increased. .

Further, an adjusting nut for adjusting the built-in spring pressure can be screwed onto the upper end of the shaft that penetrates through the body of the slider support fitting.

In the section slider support fitting of the present invention having the above-mentioned structure, the slider pushing force is adjusted depending on the conditions such as the speed of the train entering the section, the inclination angle of the pantograph, the height difference between the main trolley wire and the slider. As a result, the slider can easily and surely follow the movement of the pantograph to prevent the wire separation.

The hepantograph smoothly slides and transfers, and a slider provided on the slider support metal fitting A is a slider arranged outside the trolley wire whose tips are opposed to each other, and an insulating rod connecting the end of the trolley wire. The slider support metal fittings A are connected to each other to form one body, and hanging tool stoppers for hanging and supporting from a messenger wire or the like are formed on both sides of the slider support metal fitting A.

One end of the slider 12 has one trolley wire T
2 is formed by bending in the central portion so as to be arranged in parallel with 2 at a predetermined interval, and on the other end side so as to be arranged substantially in contact with the outer surface of the other trolley wire T1 end, The portion of the end of the trolley wire T1 that is almost in contact with the outer surface is the trolley wire T1.
And two parallel sliders which are fixed by tripliers E and E and are separated from the trolley wire, and an insulating rod connected to the end of the trolley wire are connected by the slider support fitting A to be integrated.

In this slider support metal fitting A, a rod support metal fitting 3 for sandwiching an insulating rod 4 is arranged at a central portion, and insulating materials 2 and 2, for example, insulators are attached to both sides of the rod support metal fitting 3, and this insulating material 2 2, the slider mounting metal fitting bodies 1 and 1 are connected to the outer sides of the two.

The slider mounting bracket body 1 has a base end side that can be connected to the insulating material 2, is fixed by rivets, etc., and has a tubular tip, and the tubular body 10 is penetrated. Shaft 11 is arranged under spring pressure, and ear pieces 13 and 14 for sandwiching slider 12 are attached to the lower end of shaft 11.

A shaft 11 penetrating into a tubular body 10
Fixed one ear piece 13 to the lower end, engraved a male screw on the outer peripheral surface of the upper end, screwed an adjusting nut 20 to this so as to make the spring pressure variable, and made a synthetic material such as Teflon in the main body 10. A piston retainer 15 made of resin or other material is fitted, the shaft of the piston retainer also penetrates, and a cap 16 is fitted against the piston retainer. Then, a spring 17 is inserted between the piston retainer and the cap to apply a spring pressure to the piston retainer and the cap in opposite directions. In this case, the spring retainer 19 is provided so as to abut on the piston retainer to more reliably support the spring, and a Teflon or other synthetic resin piston ring 18 is provided on the outer peripheral surface of the cap.
Is integrally provided, so that the ear piece and the shaft can be smoothly slid in the main body in the upward direction against the upward load applied to the slider.

Also, the ear pieces 13 and 14 which oppose each other
Has a cap screw 21 penetrating between the ear pieces 13 and 14 so that the trolley linear slider 12 is sandwiched at the lower end, and a nut 22 is screwed into the cap screw 21 to fasten and fix the ear pieces.

Therefore, when the trolley wire is connected and supported by using the slider support fitting of the present invention as shown in FIG. 1, the slider 12 disposed along the outer side of the trolley wire connecting portion is gripped by the ear pieces 13 and 14. And is supported via a shaft and a spring, but when the pantograph moves from the trolley wire T1 to T2 by traveling of the train, the slider 1

While supporting smooth movement in the vertical direction,
Unnecessary tilting of the shaft 11 is prevented with respect to the front / rear and left / right.

The piston retainer 15 fixed to the upper portion of the slider support metal fitting body also has the same lubricity,
It is made of a material with excellent durability, and its function is the same as the piston ring. The coil spring 17 is fixed at the upper part by the spring retainer 19, and when the pantograph approaches the support point on the outlet side and the slider is pushed up, the coil spring is compressed, and when the pantograph passes the support point, the restoring force of the coil spring causes Push the slider down to the defined position. At that time, the resistance generated between the shaft and the piston retainer, and between the outer cylinder and the piston ring can prevent residual vibration from occurring and eliminate the influence on the pantograph that enters subsequently.

The sliding surface height of the slider is as follows depending on the traveling position of the pantograph. (1) On the section entrance side (point A), the position is set higher than the trolley wire of the main line, and the structure is such that the section is not easily affected by an impact even when the pantograph inclines into the section where the section is attached.

(2) In a range (points B to C) where the insulating rod is parallel to the trolley wire, the position is lower than that of the insulating rod, and the pantograph slides only on the insulating rod to prevent current interruption during power running. It has a structure that prevents the occurrence of arcs and prevents the occurrence of arcs.

(3) At the support point (point D) on the outlet side, 2 m from the same position as the sliding surface of the section, depending on the mounting condition.
By adjusting so that the slider sliding surface comes to a position about m lower, even if the pantograph tilts into a place where the section is tilted and installed, only the slider is pushed up by the pushing force of the pantograph. The pantograph smoothly moves to the main line (trolley line) on the exit side.

[0021]

According to the slider support fitting for a section of the present invention, even if the pantograph of the train entering the section is tilted, the slider supported by the slider support fitting is pushed up by the tilt of the pantograph and the main line The pantograph passes through the section in contact with both the trolley wire and the section at the same height as the trolley wire, and the trolley wire and the pantograph on the main line keep contact with each other even at the section exit immediately after passing the section. It is possible to prevent the occurrence of an arc due to disconnection.
