Description

Collector shoe for pantograph

Technical Field

The present utility model relates to a collector shoe for a pantograph mounted on a roof of a railway vehicle running on a rail.

Background

For example, patent document 1 discloses such a collector shoe. The collector shoe is provided with: a boot body; and a sliding plate which is arranged on the upper surface of the boot body and is used for sliding contact of the overhead conductor. The slide plate is composed of a plurality of slide plate pieces arranged in a row in the sleeper direction. The elastic bodies that support the portions of the 2 runner pieces adjacent to each other are provided in the boot body at intervals in the sleeper direction. In this case, 2 support bodies having support plate portions fixed to portions of the runner pieces are vulcanization bonded to the rubber body to constitute each elastic body.

The contact area between the sliding plate of the collector shoe and the overhead conductor is small as in the conventional example. Thus, there is a problem that large-capacity current collection cannot be handled. Currently, as collector shoes for pantographs used for railway vehicles traveling in a trunk crossing section, there are used so-called flex plate type collector shoes using a flex plate made of a special titanium alloy and so-called multi-split slider type collector shoes supporting slider pieces split into a plurality of portions by rubber plates and coil springs. When a large current is to be handled by such a flexure plate type or multi-split slide plate type collector shoe, the structure of the collector shoe is complicated and the number of components is increased in any case.

Disclosure of utility model

In view of the above, an object of the present utility model is to provide a so-called crossover rubber type collector shoe which can ensure a large contact area between a runner and an overhead conductor and can realize large-capacity collection even when applied to a railway vehicle traveling at high speed.

In order to solve the above problems, a collector shoe for a pantograph according to the present utility model mounted on a roof of a railway vehicle traveling on a track includes: a boot body; and a slider provided on an upper surface of the shoe body and in sliding contact with the overhead conductor, the slider being constituted of a plurality of slider pieces arranged in a sleeper direction, and elastic bodies respectively supporting portions of 2 adjacent slider pieces being provided in the shoe body at intervals in the sleeper direction, the 2 supporting bodies having supporting plate portions fixed to portions of the slider pieces being adhered to the rubber body to constitute each elastic body, wherein the plurality of slider pieces arranged in the sleeper direction are formed as slider pieces, and the plurality of elastic bodies are further arranged in the shoe body along the track direction so that the plurality of slider pieces are arranged in parallel in the track direction.

According to the present utility model, for example, even in the bridge rubber type collector shoe having an advantage of a simpler structure than the flexure plate type or the multi-segment slider type collector shoe, since the slider blocks are arranged in a plurality of rows in the track direction, a large contact area between the slider and the overhead conductor can be ensured to realize large-capacity collection. Therefore, the present utility model can be suitably used as a collector shoe for a railway vehicle that needs to travel at a high speed and that can handle a large current.

In the present utility model, it is preferable that a biasing means for biasing the support plate portion toward the slide plate piece is further provided in the boot body. Thus, the respective slide plate pieces of the slide plate divided in the crosstie direction are supported by the respective urging units, so that the equivalent mass of the respective urging units can be reduced, and the following performance with respect to the overhead wire can be maintained even under high-speed running, which is advantageous.

Detailed Description

Hereinafter, an embodiment of the pantograph-use collector shoe CB according to the present utility model will be described with reference to the drawings, in which a pantograph mounted on a roof of a railway vehicle traveling on a track is referred to as a single-arm pantograph Sp.

Referring to fig. 1, the single-arm pantograph Sp has: a chassis 1 disposed on a roof of a railway vehicle (not shown) via an insulator (not shown); and a frame group 2 including a lower frame 21 and an upper frame 22 mounted on the chassis 1 and extending and contracting in the up-down direction orthogonal to the track direction of the railway vehicle, and supporting the collector shoe CB of the present embodiment by the upper frame 22. The lower frame 21 is swingably coupled at its lower end portion to the bracket 11 on the underframe 1 via a main shaft 21a parallel to the sleeper direction. A hinge frame 21b branched into two is provided at the upper end portion of the lower frame 21, and the upper frame 22 is swingably coupled to the hinge frame 21b via a shaft (not shown) parallel to the sleeper direction in the vicinity of the lower end thereof.

An equalizing link 3 is provided between the lower end of the upper frame 22 located below the shaft and the chassis 1, and swings the upper frame 22 and the lower frame 21 in conjunction with the swing. When the lower frame 21 is swung upward, the upper frame 22 is also swung upward, so that the frame group 2 is actuated on the upward extension side, and when the lower frame 21 is swung downward, the upper frame 22 is also swung downward, so that the frame group 2 is actuated on the downward folding side. The spring 4 disposed on the chassis 1 is coupled to the main shaft 21a via a rod 4a, and the cylinder 5 disposed on the chassis 1 is coupled to the main shaft 21a via a rod 5 a. The frame group 2 is biased upward by the spring 4, and the frame group 2 is operated downward by the cylinder 5 against the biasing force of the spring 4. Further, a balance link 6 is provided between the lower frame 21 and the collector shoe 3 described later, so that the posture of the collector shoe CB is kept constant. In fig. 1, hk is a hook unit that performs an operation on the folding side of the frame group 2 and that engages a collector shoe 3 described later at a predetermined lowering end position. The single-arm pantograph Sp itself may have a known structure, and therefore, a further detailed description thereof will be omitted.

Referring to fig. 2 to 4, the collector shoe CB includes: a box-shaped boot 71 which is long in the sleeper direction; a slider 72 provided to close an upper surface opening of the shoe 71 and to be in sliding contact with the overhead conductor Tw; and horn 73 protruding from both sides of the shoe 71 in the sleeper direction, respectively, for lifting and pulling in the overhead wire Tw when the railway vehicle is traveling. The slide plate blocks 72 ₁、72₂ formed by arranging the plurality of slide plate pieces 72a, 72b in the sleeper direction are arranged in parallel in the track direction in 2 rows, thereby forming the slide plate 72 made of a material having good conductivity such as copper alloy. The portions of the 2 slide plates 72a, 72b of the slide plate block 72 ₁、72₂ adjacent to each other are supported by the elastic bodies 8, in other words, a plurality of elastic bodies 8 are also arranged in the shoe 71 in the track direction in such a manner that the slide plates 72 ₁、72₂ of the plurality of slide plates are juxtaposed in the track direction.

The elastic body 8 is constituted by 2 supporting bodies 81 and a rubber body 82. Each support 81 has a substantially コ -shaped cross-section and has: support plate sections 81a fixed to lower surface portions of the runner pieces 72a, respectively; a side plate portion 81b bent from one end of the support plate portion 81a in the sleeper direction; and a bottom plate portion 81c bent from the lower end of the side plate portion 81b so as to extend parallel to the support plate portion 81 a. The rubber body 82 is sandwiched between the two side plate portions 81b in a posture in which the support plate portions 81a are directed in opposite directions, and vulcanization adhesion is performed so that the periphery of the bottom plate portion 81c is covered with rubber (see fig. 4). In a state where the slide plate 72 is provided so as to close the upper surface opening of the boot 71, the bottom plate portion 81c abuts against the bottom surface of the boot 71, thereby functioning as a stopper. The ends of the slide plate pieces 72b located on both sides in the sleeper direction are supported by other support bodies 9. The other support body 9 is also configured by vulcanizing and bonding a rubber body 92 to a support plate portion 91 fixed to the lower surface portion of the runner piece 72 b.

A coil spring Cs as urging means is disposed in the shoe 71 in correspondence with the position of the support plate portion 81 a. In a state where the slide plate 72 is provided so as to close the upper surface opening of the shoe 71, the support plate portion 81a is biased toward the slide plate piece 72a by the coil spring Cs. Further, although members necessary for collecting electric power from the overhead conductor Tw such as a flexible copper wire are provided in the shoe 71, they can be configured in a known manner, and therefore, a detailed description thereof is omitted here.

As described above, for example, even in the bridge rubber type collector shoe having an advantage of a simpler structure than the flexure plate type or the multi-split runner type collector shoe, since the runner blocks 72 ₁、72₂ are arranged in a plurality of rows in the track direction, a large contact area between the runner 72 and the overhead conductor Tw can be ensured, and large-capacity collection can be achieved. Therefore, the present invention can be suitably used as a collector shoe for a railway vehicle that needs to travel at a high speed and that can handle a large current. Further, by providing the coil springs Cs to support the respective runner pieces 72a, 72b of the runner 72 divided in the crosstie direction, the equivalent mass of each coil spring Cs can be reduced, and the following performance with respect to the overhead wire Tw can be maintained even during high-speed running, which is advantageous.

The embodiments of the present utility model have been described above, but various modifications are possible without departing from the scope of the technical idea of the present utility model. In the above embodiment, the explanation has been given taking the case where the 2-row slider blocks 72 ₁、72₂ are arranged in parallel in the track direction, but the present utility model is not limited thereto, and the elastic body 8 may be further arranged in the shoe 71 in the track direction so that 3 or more rows of slider blocks are arranged in parallel in the track direction. Thereby, a larger contact area of the slider 72 and the overhead wire Tw can be ensured.
