Description

  The present invention relates to an improvement in a current collecting boat device used in a state where it is installed on a roof of a railway vehicle operating at a high speed, such as a Shinkansen, in order to take in electric power from an overhead line, and to improve the followability of the sliding plate to the overhead line. Is.

  A current collector boat is supported above the roof of the railway vehicle via a pantograph so that power can be taken from the overhead line. That is, a sliding plate made of a conductive material such as sintered metal supported on the upper surface of the current collector boat is elastically pressed toward the lower edge of the overhead wire, and electric power is taken into the vehicle from this overhead wire. Among such pantographs and current collector boats, those used for high-speed vehicles such as the Shinkansen were used for conventional lines in consideration of reduction of airflow noise generated during operation and followability to overhead lines. A different structure is used.

  FIG. 22 shows a current collecting boat apparatus developed for a high-speed vehicle in consideration of such points as described in Patent Document 1. In the case of this conventional structure, an intermediate portion of the ceiling tube 2 is supported on the upper end portion of the upper frame 1 constituting the pantograph, a hollow boat body 3 is provided around the ceiling tube 2, and the ceiling tube 2 is slightly It is elastically supported so that it can be raised and lowered. For this purpose, linear shafts 4 and 4 and springs 5 and 5 and conducting wires 6 and 6 for energization are provided in the boat body 3. The sliding plate 7 is installed on the upper surface of the boat body 3.

  Because of such a structure, air does not flow around the ceiling tube 2, the linear shafts 4, 4, the springs 5, 5, and the conductors 6 and 6 even during high-speed operation, and airflow noise can be reduced accordingly. Further, when the vertical position of the overhead line changes finely, the boat body 3 is displaced with respect to the ceiling pipe 2 to follow this change. In other words, it is not necessary for the ceiling pipe 2 to be displaced in the vertical direction. Therefore, the inertial mass of the portion displaced in the vertical direction in order to follow the overhead wire can be reduced, and the followability to the overhead wire can be improved. When the vertical position of the overhead line changes greatly, the upper frame 1 is moved up and down to cause the sliding plate 7 to follow the overhead line. Moreover, the ceiling pipe said in the field of the current collector boat apparatus for rail vehicles means the support frame-like member arrange | positioned in the width direction of a vehicle at the upper end part of a pantograph. Previously (in the case of the diamond-shaped pantograph used in conventional lines), it was actually configured in a tubular shape, but now it is not necessarily in a tubular shape (especially for high-speed railways).

  In the case of the conventional structure described in Patent Document 1 as described above, the air flow noise can be reduced and the followability to the overhead line can be improved as compared with the conventional structure. Still has room for improvement. That is, in the case of the conventional structure, when the vertical position of the overhead wire is finely changed, the boat body 3 and a pair of left and right frame bars 8 and 8 fixed to the boat body 3 are connected to the sliding plate. 7 Go up and down with the whole. Therefore, although the ceiling tube 3 and the upper frame 1 are not included, it is inevitable that the inertial mass is considerably increased. For this reason, when the speed of the railway vehicle is increased, the contact between the upper surface of the sliding plate 7 and the overhead wire may be deteriorated. The springs incorporated in the pantograph to give the upper frame 1 elasticity in the standing direction, and the springs 5 and 5 that give the ceiling pipe 2 elasticity in the upward direction with respect to the boat body 3 are increased. Thus, the following ability can be improved. However, in this case, the contact surface pressure between the upper surface of the sliding plate 7 and the overhead wire becomes high, and the abrasion of the sliding plate 7 and the overhead wire becomes remarkable.

Japanese Patent No. 3297355

  In view of the circumstances as described above, the present invention further reduces the inertial mass of the portion displaced in the vertical direction together with the sliding plate in contact with the overhead wire, thereby reducing the elasticity of the spring for pressing the sliding plate against the overhead wire. The present invention has been invented to improve the followability of the sliding plate to the overhead wire without increasing the size.

Each of the current collecting boat apparatuses according to the present invention has a hull supported in the width direction of the vehicle at the upper end of the pantograph, and a slide disposed in the width direction of the vehicle along the hull above the hull. A plate support assembly and a slide plate supported and fixed on the upper surface of the slide plate support assembly are provided.
The sliding plate support assembly is configured such that the arrangement direction ends of a plurality of support pieces that are divided in the width direction of the vehicle and arranged in series in the width direction are connected to each other so as to be swingable and displaceable. It consists of.
The sliding plate is formed by supporting and fixing a plurality of sliding plate elements divided into the same number as the support pieces on the upper surfaces of the support pieces.
An elastic member that presses the support pieces upward is provided between the support pieces and the boat body.
Further, the end portions of the support pieces are connected to each other by a connecting shaft arranged in the traveling direction of the vehicle so as to be swingable and displaceable.
Further, in the case of the current collecting boat apparatus according to claim 1, a part of the connecting shaft and a portion of the upper surface of the boat body that is shifted from the connecting shaft in the width direction of the vehicle are arranged in the traveling direction of the vehicle ( = Both end portions of the link member are connected to a pivot arranged in parallel (in parallel with the connecting shaft) so as to be swingably displaceable.
On the other hand, in the case of the current collecting boat device according to claim 2, the lifting shaft is arranged in the middle part in the width direction of the vehicle among some of the support pieces, and parallel to the connecting shaft (= vehicle). In the direction of travel). Then, both end portions of the link member are swung to at least a part of the lifting shaft and a pivot arranged in the traveling direction of the vehicle at a portion shifted in the vehicle width direction from the lifting shaft on the upper surface of the boat body. It is connected so that it can be displaced freely.

According to the current collecting boat apparatus of this invention comprised as mentioned above, the inertial mass of the part displaced to an up-down direction with the sliding board which contacts an overhead wire can fully be reduced. That is, among a plurality of sliding plate elements constituting the sliding plate installed on the upper surface of the current collecting boat device, one or two of the sliding plate elements that rub against the overhead wire (the overhead wire exists between adjacent sliding plate elements). In the case). Further, the support pieces that support each of the sliding plate elements on their respective upper surfaces are connected to each other so as to be swingable and displaceable. Therefore, when the vertical position of the overhead wire changes finely, in order to keep the overhead wire and the sliding plate in contact with each other, the one or two sliding plate elements that are in friction with the overhead wire and the sliding plate are in contact with each other. Only the support piece supporting the plate element needs to be raised and lowered. These one or inertial mass of the supporting support pieces of two contact strip elements and the sliding plate device, much in comparison to the inertial mass of the combination of the collector head and the entire contact strip (all contact strip element) small. Accordingly, the followability of the sliding plate to the overhead wire can be improved without increasing the elasticity of the spring for pressing the sliding plate element against the overhead wire.
Further, since both ends of the link member are connected to a part of the connecting shaft or a part of the lifting shaft and the pivot so as to be swingable and displaceable, the support pieces are prevented from being displaced in the arrangement direction. The posture of each support piece can be stabilized, and the contact state between the upper surface of the sliding plate element supported on the upper surface of each support piece and the overhead wire can be stabilized.

When implementing the present invention as described above, preferably, as described in claim 3, a plurality of guide brackets each having a guide hole that is long in the vertical direction are fixed on the upper surface of the boat body. And each connection shaft which connects the edge parts of each said support piece, or a part of raising / lowering axis | shaft provided in the intermediate part of one part support piece is freely loosened freely to each said guide hole.
If comprised in this way, the attitude | position of each said support piece can be stabilized further, and the contact state of the upper surface of the said sliding board element and an overhead wire can be stabilized further.

Further, when the present invention is carried out, preferably, as described in claim 4 , each of the support pieces and each of the sliding plate elements are formed by connecting the upper surface of each of the support pieces and the lower surface of each of the sliding plate elements . In the middle, a single energizing plate is sandwiched and fixed. As this energization plate, a copper plate or a thin plate made of a copper alloy can be used. A portion of the energization plate that is located between the portions sandwiched between the upper surface of each of the support pieces and the lower surface of each of the sliding plate elements is the support pieces adjacent to each other in the vehicle width direction. In order to reduce the force required for the relative displacement in the vertical direction between the sliding plate elements, the width dimension in the traveling direction of the vehicle is made smaller than the sandwiched portions .
If comprised in this way, each said sliding board element can be connected so that electric power delivery is possible. Therefore, as long as the power supply plate is connected to the power cable, power can be taken into the power cable from the overhead wire, even if the overhead wire rubs against any sliding plate. In other words, it is not necessary to individually connect each of the sliding plate elements and the power cable, and the wiring for taking in the power can be simplified to facilitate the assembly work of the current collector boat device.
In this way, even when all the sliding plate elements are made conductive by a single energizing plate, a part of the conductive plate is sandwiched between the upper surface of each supporting piece and the lower surface of each sliding plate element. Since the width of the portion located between the two portions is narrow and the rigidity is low, the followability of each sliding plate element to the overhead wire can be improved.
When the invention described in claim 4 is carried out, more preferably, as described in claim 5 , a part of the energization plate where the width dimension is smaller is lower than the other part. A curved portion protruding in
If comprised in this way, the force which the relative displacement of the up-down direction of each said adjacent support piece and each sliding plate element will be made smaller, and the followability to the overhead wire of each said sliding plate element will be improved further. I can do things.

The current collecting boat apparatus according to the first embodiment of the present invention shown in FIGS. 1 to 6 includes a boat body 3a, a sliding plate support assembly 9, and a sliding plate 7a.
Of these, the hull 3a is supported over the width direction of the railway vehicle at the upper end of a pantograph frame (not shown). Between the hull 3a and the pantograph frame, there is provided a link mechanism (not shown) that has been conventionally known in the technical field of pantograph devices for railway vehicles, regardless of whether the pantograph frame is raised or lowered. The upper surface of the boat body 3a is parallel to the roof surface of the vehicle.

  The sliding plate support assembly 9 is arranged above the boat body 3a in the width direction of the railcar along the boat body 3a, and a plurality of support pieces 10a and 10b are combined in series. It consists of That is, the sliding plate supporting assembly 9 is divided in the width direction of the vehicle, and the end portions in the arrangement direction of the plurality of support pieces 10a, 10b arranged in series in the width direction are connected to the connecting shaft 11, 11 are connected to each other so as to freely swing and displace. Of the support pieces 10a and 10b, the support pieces 10a and 10a located at both ends in the width direction of the railway vehicle are supported and fixed on the upper surfaces of the both ends of the boat body 3a. On the other hand, the remaining support pieces 10b and 10b located in the intermediate portion are in a state where a space is interposed between the lower surface and the upper surface of the boat body 3a by the connecting shafts 11 and 11, respectively. It is supported. The inner diameters of the support holes 12, 12 formed at the ends of the support pieces 10 a, 10 b are slightly larger than the outer diameters of the connection shafts 11, 11. Therefore, the sliding plate support assembly 9 can be freely displaced in the bending direction and somewhat expanded and contracted like a wristwatch metal band. Then, the remaining support pieces 10b and 10b located in the intermediate portion are supported above the boat body 3a so as to be slightly movable up and down.

  Between the lower surfaces of the support pieces 10b and 10b located in such an intermediate portion and the upper surface of the boat body 3a, the support members 10b and 10b are elastic members described in the claims. Compression coil springs 13 are provided. Accordingly, the support pieces 10b and 10b located in the intermediate portion are given elasticity in the upward direction. Further, based on this elasticity, in order to prevent the support pieces 10b, 10b from being displaced excessively upward, the connecting shafts 11, 11 are inserted into the guide holes 15, 15 of the guide brackets 14, 14, respectively. I'm going to play together. Each of these guide brackets 14 and 14 is fixed to the upper surface of the boat body 3a, and each of the guide holes 15 and 15 is a long hole that is long in the vertical direction. Further, the width dimension of each of the guide holes 15 and 15 is slightly larger than the outer diameter of each of the connecting shafts 11 and 11. With this configuration, the support pieces 10b and 10b located in the intermediate portion are slightly supported (e.g., support pieces at both ends of the neutral position with respect to the neutral position in a state where elasticity is given upward above the boat body 3a. 10b and 10b are supported up and down freely (about ± 3 mm, and support pieces 10b and 10b near the center are about ± 5 mm).

  In addition, one end of each of the link members 16 and 16 is swingably displaceable to a part of the connection shafts 11 and 11 of the connection shafts 11 and 11 that connect the support pieces 10b and 10b positioned at the intermediate portion. It is linked to. The other end portions of the link members 16 and 16 are connected to pivots 17 and 17 installed on the upper surface of the boat body 3a so as to be swingable and displaceable. The connecting shafts 11 and 11 and the pivots 17 and 17 that connect both end portions of the same link member 16 and 16 are arranged in the traveling direction of the railway vehicle at portions shifted in the width direction of the railway vehicle. ing. With this configuration, the sliding plate support assembly 9 constituted by the support pieces 10a and 10b has a rigidity in the width direction of the railway vehicle. In addition, some gap is provided also about the connection part of the both ends of each said link member 16 and 16, and each said connection shafts 11 and 11 and each said pivots 17 and 17, and each said link member 16, 16 can be raised and lowered and the support pieces 10b and 10b positioned in the intermediate portion can be moved up and down.

  As described above, the sliding plate 7a is installed on the upper surface of the sliding plate supporting assembly 9 installed above the boat body 3a. The sliding plate 7a is formed by arranging sliding plate elements 18a and 18b divided in the same number as the support pieces 10a and 10b in series in the width direction of the railway vehicle. Each of the sliding plate elements 18a and 18b is supported and fixed to the upper surface of each of the support pieces 10a and 10b by screwing or the like. Accordingly, among the sliding plate elements 18a and 18b, the sliding plate elements 18b and 18b supported and fixed on the upper surfaces of the support pieces 10b and 10b located in the intermediate portion, together with the respective support pieces 10b and 10b, It can move up and down slightly. The upper surfaces of the sliding plate elements 18a and 18b are located on the same horizontal plane when the railway vehicle is present in a flat portion and the support pieces 10a and 10b are present in neutral positions.

  According to the current collecting boat device of the present embodiment configured as described above, when the inertial mass of the portion displaced in the vertical direction together with the sliding plate 7a in contact with the overhead wire is sufficiently reduced, the speed of the railway vehicle is increased. Moreover, the followability of the sliding plate 7a with respect to the overhead wire can be ensured. In other words, in the case of the structure of the present embodiment, the sliding plates 7a installed on the upper surface of the current collecting boat device are divided into a plurality (10 at the middle part for raising and lowering, and 12 including the fixed parts located at both ends). It is divided. During normal traveling, the overhead wire rubs against the upper surfaces of the sliding plate elements 18b and 18b supported and fixed on the upper surfaces of the support pieces 10b and 10b located at the intermediate portion. The overhead wires rub against the upper surfaces of the sliding plates 18a, 18a at both ends only when traveling at a low speed, such as when passing a point.

  Further, during normal (high speed) traveling, the one that rubs against the overhead wire is one or two of the sliding plate elements 18b, 18b supported and fixed on the upper surfaces of the support pieces 10b, 10b located in the intermediate portion. Only the sliding plate element 18b is provided. That is, in many cases, the overhead line rubs against the upper surface of any one sliding plate element 18b. In this state, when the vertical position of the overhead wire changes finely, the one sliding plate element 18b rises based on the elasticity of the compression coil spring 13 provided between the lower surface thereof and the upper surface of the boat body 3a. Or, it descends against the elasticity of the compression coil spring 13. In addition, when the overhead line is finely changed in a state where the overhead line is located between the two adjacent sliding plate elements 18b and 18b, the two adjacent sliding plate elements 18b and 18b are Ascending based on the elasticity of the compression coil springs 13 and 13 provided between the lower surface thereof and the upper surface of the boat body 3a, or descending against the elasticity of the compression coil springs 13 and 13, respectively.

  In any of these cases, the inertia mass of the one or two sliding plate elements 18b and the support piece 10b that supports the sliding plate elements 18b is the entire sliding plate 7a (all sliding plate elements 18a and 18b). Is much smaller than the inertial mass of the boat body 3a. Further, when any one of the sliding plate elements 18b and the support piece 10b supporting the sliding plate element 18b are moved up and down, the adjacent sliding plate elements 18b and the supporting piece 10b supporting the sliding plate element 18b are somewhat attached thereto. Even in this case, the inertial mass of the part that moves up and down is much smaller than the inertial mass that combines the entire sliding plate 7a and the boat body 3a. Therefore, without increasing the elasticity of the compression coil springs 13 and 13 for pressing the sliding plate elements 18b and 18b against the overhead wire, the sliding plate 7a against the overhead wire, that is, the sliding plate elements 18b and 18b, The followability of 18b can be improved. As a result, the speed of the railway vehicle can be increased without reducing the durability of each of the sliding plate elements 18b and 18b and the overhead wire. In general, the sliding plate constituting the current collecting boat apparatus is often divided into two in the traveling direction of the railway vehicle. Therefore, also when the present invention is implemented, each of the sliding plate elements 18a and 18b is divided into two in the traveling direction as necessary.

  FIG. 7 shows a second embodiment of the present invention. In the case of the present embodiment, the number of dividing the sliding plate 7b with respect to the width direction of the railway vehicle is made smaller than in the case of the first embodiment described above. That is, the width dimension Wb of the sliding plate elements 18b and 18b arranged at both ends of the sliding plate elements 18b and 18c located in the intermediate portion is the same as in the case of the above-described first embodiment. The width dimension Wc of the remaining sliding plate elements 18c, 18c arranged in the portion is approximately twice the width dimension Wb (Wc≈2Wb) of the sliding plate elements 18b, 18b arranged near the both ends. In accordance with this, the width dimensions of the support pieces 10b and 10c for supporting and fixing the sliding plate elements 18b and 18c on the upper surfaces thereof are also different from each other between the end portions and the center portion.

In the case of this embodiment, the guide holes of the guide bracket 14a in which the elevating shafts 19 and 19 provided at the center in the width direction of the support pieces 10c and 10c in the central portion are fixed on the upper surface of the boat body 3a. In 15a, it can be freely raised and lowered. Then, one end of each of the link members 16 and 16 is pivotally supported on each of the lift shafts 19 and 19 to suppress the displacement in the width direction of the support pieces 10c and 10c. Further, compression coil springs 13 and 13 are respectively provided between two positions where the lifting shafts 19 and 19 are sandwiched from both sides in the width direction on the lower surfaces of the support pieces 10c and 10c and the upper surface of the boat body 3a. Yes.
In the case of the present embodiment configured as described above, in the same manner as in the case of the first embodiment described above, the followability of each of the sliding plate elements 18b and 18c with respect to the overhead wire is improved, and each of these sliding plate elements 18b, The speed of the railway vehicle can be increased without reducing the durability of the 18b and the overhead wire.

8 to 21 show a third embodiment of the present invention. The present embodiment embodies the above-described first embodiment and adds a current plate. The parts corresponding to the structure of the first embodiment are denoted by the same reference numerals, and the explanation regarding the overlapping parts is simplified and a part thereof is omitted. Hereinafter, the characteristic part of the present embodiment, The description will focus on the structural portion that has not been described in the first embodiment.
The boat body 3a is formed in a ship shape in which a standing wall portion 21 is provided around the bottom plate portion 20 by machining a material made of an aluminum alloy or by die casting. A plurality of support pieces 10a and 10b that are swingably displaced by connecting shafts 11 and 11 are housed in the upper part of the inside of the boat body 3a. Each of these support pieces 10a and 10b is also made by cutting out a material made of an aluminum alloy or by die casting. Each of the support pieces 10a, 10b includes a flat plate-like support plate portion 22, a pair of hanging wall portions 23, 23 bent downward from both ends of the support plate portion 22 with respect to the traveling direction of the vehicle, The arm portions 24, 24 extending from the end edges of the both hanging wall portions 23, 23 are provided in the width direction.

  The support pieces 10a and 10b are connected to each other so as to be swingable and displaceable by inserting the connection shafts 11 and 11 into the distal ends of the arm portions 24 and 24, respectively. Is configured. Further, the support pieces 10a located at both ends are fixed to the end of the bottom plate portion 20 by screws 25, 25 via a fixing plate 30 described later. On the other hand, the positions of the two intermediate portions of the connecting shafts 11 and 11 that connect the support pieces 10b and 10b positioned at the intermediate portion are loosely engaged with the guide holes 15 and 15 of the guide brackets 14 and 14, respectively. The support pieces 10b and 10b positioned at the intermediate portion are supported above the bottom plate portion 20 so as to be slightly raised and lowered. Further, link members 16 and 16 are provided between the pivot shafts 17 and 17 supported by a part of the guide brackets 14 and a part of the connection shafts 11 and 11 so as to be swingable and displaceable.

  As described above, the slide plate elements 18a and 18b are respectively connected to the upper surfaces of the support plate portions 22 and 22 of the support pieces 10a and 10b connected by the connection shafts 11 and 11 through the current supply plate 26, respectively. The support is fixed. The width dimension of each of the sliding plate elements 18a and 18b with respect to the width direction of the vehicle is larger than the width dimension of each of the support plate portions 22 and 22. Accordingly, both end portions of each of the sliding plate elements 18a and 18b are projected from the end edges of the respective supporting plate portions 22 and 22 in the width direction of the vehicle. Further, with respect to the width direction of the vehicle, the edges of the sliding plate elements 18a and 18b are inclined with respect to the traveling direction of the vehicle and are close to each other with a minute gap therebetween. The reason for this configuration is that even when the overhead wire is located at a discontinuous portion of the adjacent slide plate elements 18a and 18b, the overhead wire is prevented from sinking into the discontinuous portion, and the slide plate elements 18a and 18b This is to prevent the sliding plate elements 18a, 18b and the overhead wire from being damaged by preventing excessive surface pressure from acting on the rubbing portion between the sliding wire and the overhead wire.

  The energization plate 26 is a thin plate made of copper or a copper-based alloy, and is provided only for one current collecting boat device. The energizing plate 26 has adjacent flat plates with wide flat plate portions 27a and 27b sandwiched between the upper surfaces of the support pieces 10a and 10b and the lower surfaces of the sliding plate elements 18a and 18b. Between the portions 27a and 27b, curved portions 28 and 28 are formed which are narrow and project downward from the flat plate portions 27a and 27b. The sliding plate elements 18a and 18b are placed on the upper surfaces of the supporting plate portions 22 and 22 via the flat plate portions 27a and 27b, respectively, and are supported by the supporting plate portions 22 and 22 and the flat plate portions. 27a and 27b are supported and fixed to the support plate portions 22 and 22 by screws 29 and 29 inserted from below. In this state, the curved portions 28 and 28 are located between the adjacent support pieces 10a and 10b and below the discontinuous portions of the adjacent sliding plate elements 18a and 18b. Since the bending portions 28 and 28 have low bending rigidity and can be expanded and contracted, the force required for the relative displacement in the vertical direction between the adjacent support pieces 10a and 10b is small. In addition, an end portion of a cable (not shown) is connected to a part of the energizing plate 26 to take in electric power taken from the overhead line to the vehicle side.

  Further, compression coil springs 13 and 13 are respectively provided between the lower surface center portions of the support plate portions 22 and 22 of the support pieces 10b and 10b located in the intermediate portion and the upper surface of the bottom plate portion 20 of the boat body 3a. Provided. In the case of the present embodiment, a fixing plate 30 provided with the guide bracket 14 and the like on the upper surface thereof is fixed to the upper surface of the bottom plate portion 20 with screws 31, 31, and the compression coil springs 13, 13 is provided between the upper surface of the fixed plate 30 and the center of the lower surface of each of the support plate portions 22 and 22. With this configuration, the sliding plate elements 18b and 18b fixed to the upper surfaces of the support plate portions 22 and 22 of the support pieces 10b and 10b by applying upward elasticity to the support pieces 10b and 10b, It is made to press elastically toward the overhead wire. In the illustrated example, circular or annular recesses 32a and 32b for fitting the compression coil springs 13 and 13 are provided on a part of the upper surface of the fixed plate 30, and these compression coils are provided. The springs 13 and 13 are positioned. Further, circular holes 33 and 33 having inner diameters larger than those of the compression coil springs 13 and 13 are formed in the central portions of the link members 16 and 16, and the compression coil springs 13 and 13 are installed. It is possible.

The current collecting boat apparatus of the present embodiment as described above is used in a state in which the center portion of the lower surface of the boat body 3a is supported by the upper end portion of a pantograph frame (not shown) and the overhead wire is in sliding contact with the upper surface of the sliding plate 7a. The When the vertical position of the overhead line slightly changes, as described in the first embodiment, the sliding plate element 18b that is in contact with the overhead line at that time moves up and down, and the sliding contact state with the overhead line is reached. Is maintained properly.
In addition, with respect to the width direction of the vehicle, the base ends of the pair of frame bars 8 are fixed to both ends of the boat body 3a. Each of these frame bars 8 may rarely come off the side of the boat body 3a from the upper side of the boat body 3a when the railway vehicle passes a point. The overhead wire is provided again to scoop up the boat body 3a.
