DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slider support for a section, in particular, even when the inclination of the section and the inclination of the pantograph at the time of entering the section are largely different, the pantograph moves smoothly without separating from the trolley wire, The present invention relates to a section support bracket for suppressing generation of an arc.

[0002]

2. Description of the Related Art Conventionally, a section insulator generally used as a sorting device includes a trolley wire mounting bracket for directly gripping a trolley wire, an insulator for electrically separating front and rear sections, and a conductor arranged in the insulator. It is composed of a slider attached to the trolley wire, and is disposed linearly between the ends of the trolley wire with a section insulator interposed between the trolley wires. The two sliders and the insulator are integrally attached with a slider support.
The slider support is rigidly engaged with the slider.

[0003]

In the above-mentioned conventional section, the pantograph is largely separated when it slides on the slider and moves to the exit side trolley wire (main line). The derailment tends to increase as the train speed increases, and the derailment easily occurs when the pantograph inclines and enters the section. This is because the rigidity of the conventional slider is high, so that the following characteristics of the pantograph gradually decrease as the train speed increases, and the pantograph is separated without smooth transition between the slider and the exit side trolley wire. In particular, when the inclination of the section itself and the inclination of the pantograph when entering the section are significantly different as in the latter case, the transition is made such that the pantograph jumps from the slider to the main line at the exit side of the section, There has been a problem that an arc is generated due to a large separation. In view of the above, the present invention provides the above-described conventional slider for a section by adopting a structure in which the slider is supported at the outlet side from a fixed type as in the related art to a certain degree of movement in the pushing direction. It is an object of the present invention to solve the problems of the support bracket and to provide a section slider support bracket that can prevent the pantograph from separating and suppress the occurrence of arcs.

[0004]

In order to achieve the above object, a section slider supporting bracket according to the present invention, in a section provided between trolley wires to be connected, is provided along an insulating rod provided between trolley wires. A slider support is provided so that the slider is sandwiched between the slider and the insulating rod, and the slider is mounted at the lower end of the shaft supported by a slider mounting bracket main body disposed at the tip of the slider support under spring pressure. Attach the ear piece to be pinched,
It is characterized in that the slider can be pushed up by a pantograph and supported against the spring pressure when the train passes.

In the section slider supporting bracket 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 supporting bracket is pushed up by the inclination of the pantograph. The pantograph is at the same height as the trolley wire of the main line and passes through the insulated rod section by contacting both the slider and the insulating rod, and even at the section exit immediately after passing this section, the trolley line of the main line and the pantograph contact without separating. Can be maintained, and generation of an arc due to wire breakage can be prevented beforehand.

In this case, a piston retainer, a spring and a cap made of a material having excellent lubricity and excellent in durability are fitted into the slider support bracket main body, and the piston retainer, the spring and the cap are penetrated. Along with inserting the shaft, a piston ring made of a material having excellent lubricity and excellent durability can be provided on the outer periphery of the cap.

In the section slider supporting bracket of the present invention having the above-described structure, the slider is pushed up by the pantograph, and the cap fitted with the piston ring supports the vertical movement smoothly when compressing the spring. Unnecessary tilting of the shaft with respect to the front, rear, left and right can be prevented, so that it is possible to move smoothly even when the slider is pushed up by a tilted pantograph or the like, and it is possible to prevent the pantograph from separating even when the train speeds up. .

Further, an adjusting nut for adjusting a built-in spring pressure can be screwed into an upper end of the shaft penetrating the inside of the slider supporting bracket main body.

In the section slider supporting bracket of the present invention having the above-described structure, the slider pushing force is adjusted by conditions such as the speed of the train entering the section, the inclination angle of the pantograph, and the height difference between the main trolley wire and the slider. Therefore, the slider can easily and surely follow the movement of the pantograph to prevent disconnection.

On the both sides of the slider supporting bracket A, suspension stoppers for suspending and supporting from a messenger wire or the like are formed.

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

The slider supporting member A has a rod supporting member 3 for sandwiching an insulating rod 4 at a center portion, and insulating members 2 and 2, for example, insulators are attached to both sides of the rod supporting member 3. 2 are connected to the slider mounting bracket main bodies 1 and 1 respectively.

The slider mounting bracket main body 1 has a base end side in a shape connectable to the insulating material 2 and is fixed with a rivet or the like, and a tip end is formed in a cylindrical shape so as to penetrate through the cylindrical main body 10. The shaft 11 is disposed under spring pressure, and ear pieces 13 and 14 for holding the slider 12 are attached to the lower end of the shaft 11.

A shaft 11 penetrating into a cylindrical main body 10
Is fixed to one of the ear pieces 13 at the lower end, an external thread is engraved on the outer peripheral surface of the upper end, and an adjusting nut 20 is screwed into the male screw so as to make the spring pressure variable, and a synthetic material such as Teflon is inserted into 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 is more securely supported by interposing a spring retainer 19 in contact with the piston retainer, and a piston ring 18 made of Teflon or other synthetic resin is provided on the outer peripheral surface of the cap.
Are provided integrally with each other, whereby the inside of the main body can be smoothly slid in the pushing up direction together with the ear piece and the shaft against the pushing up load applied to the slider.

Further, ear pieces 13 and 14 opposing each other are provided.
Is to penetrate a cap screw 21 between the ear pieces 13 and 14 so as to sandwich the trolley linear slider 12 at the lower end, and screw a nut 22 to this to fasten and fix the gap between the ear pieces.

Accordingly, when the trolley wire is connected and supported by using the slider supporting bracket of the present invention as shown in FIG. 1, the slider 12 disposed along the outside of the trolley wire connection portion is gripped by the ear pieces 13 and 14. And is supported via a shaft and a spring. When the pantograph moves from the trolley wire T1 to T2 by traveling of the train, the slider 1
Also contacts 2. When the slider 12 is pushed up by the pantograph, the shaft 11 and the cap 1 are held together with the ear pieces 13 and 14 which sandwich the slider and are integrated.
6 also pushes up and compresses the coil spring 17. At this time, the outer periphery of the cap 16 incorporates the piston ring 18 using a material having excellent lubrication and excellent durability.
While supporting smooth movement in the vertical direction,
Unnecessary tilting of the shaft 11 in the front-rear and left-right directions is prevented.

Incidentally, the piston retainer 15 fixed to the upper part of the slider supporting bracket main body is also rich in lubricity of the same quality.
It is made of a material with excellent durability, and its function is the same as that of 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 coil spring 17 is restored by the restoring force of the coil spring. Push the slider down to the defined position. At this time, the resistance generated between the shaft and the piston retainer and between the outer cylinder and the piston ring prevents the occurrence of residual vibration, and can eliminate the influence on the pantograph that subsequently enters.

The sliding surface height of the slider is determined as follows depending on the running position of the pantograph. (1) On the section entrance side (point A), the position is higher than the trolley wire of the main line, and a structure that is hard to receive an impact even when the pantograph enters in an inclined position where the section is installed at an inclination.

(2) In a range (points B to C) where the insulating rod is parallel to the trolley wire, the insulating rod is set at a lower position than the insulating rod, and the pantograph slides only on the insulating rod to prevent current interruption during power running. A structure that prevents the occurrence of an arc and does not cause the occurrence of an arc.

(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 the slider's sliding surface to a position about m lower, even when the pantograph slops into a section where it is installed with an inclination, the slider only is pushed up by the pantograph's push-up force. , And the pantograph smoothly transitions to the main line (trolley line) on the exit side.

[0021]

According to the section slider supporting bracket of the present invention, even if the pantograph of the train entering the section is inclined, the slider supported by the slider supporting bracket is pushed up by the inclination of the pantograph, and the main line is lifted. The trolley line is at the same height as the trolley line and the pantograph passes through the section in contact with both the trolley line and the section, and the main trolley line and the pantograph maintain contact without disconnection even at the section exit immediately after this section. Therefore, it is possible to prevent the occurrence of an arc due to wire breakage.

Further, according to the slider supporting bracket for section of the present invention, the slider is pushed up by the pantograph,
When compressing the spring, the cap fitted with the piston ring supports the movement in the vertical direction smoothly and prevents unnecessary tilting of the shaft to the front, back, left and right, so even when pushing up the slider with a tilted pantograph etc. It is possible to move smoothly, and it is possible to prevent the pantograph from breaking off even when speeding up the train.

Further, according to the section slider supporting bracket of the present invention, the slider lifting force is adjusted according to 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, and the like. Therefore, the slider can easily and surely follow the movement of the pantograph to prevent disconnection.
