JP6590544B2 - Overhead structure for charging stations of storage battery vehicles - Google Patents

Description

  The storage battery vehicle stops at a charging station provided outdoors and charges the battery from the charging overhead line via the current collector. The present invention relates to an overhead wire structure provided in a charging station of a storage battery vehicle.

  The charging station where the storage battery vehicle stops and charges the battery is installed at, for example, a station, a stop, or a track. The charging station is provided with a charging overhead line in order to perform high-current charging. The charging overhead line is a partial overhead line made of a rigid trolley or the like installed over a distance of several meters to several tens of meters at a charging station (see Patent Document 1). The rigid trolley is composed of a conductive metal rail having a T-shaped cross section (for example, Patent Document 2), a trolley wire held and fixed by a pair of support saddles under an aluminum T-shaped material (for example, Patent Document 3), Known is a type in which a trolley wire is sandwiched between lower edges of a mold aluminum rigid body (for example, Patent Document 4).

  Each of the conventional rigid trolleys has a horizontal plate-like portion at the top. For this reason, in cold regions, it is easy for snow to accumulate on the plate-shaped part, and there is a risk that the accumulated snow will fall and damage the vehicle and the current collector. Since the rigid trolley has a large weight and a large amount of deflection when the weight increases due to snow accumulation, it is necessary to make the support point interval relatively small (for example, a maximum distance of 6 m for an overhead wire length of 25 m). Corresponding to this, there is a difficulty in that the cost for the support is increased. Further, the rigid trolley itself is a large heavy object and relatively expensive. Accordingly, an object of the present invention is to provide an overhead wire structure for a charging station that can prevent snow accumulation, can reduce the equipment cost by taking a relatively large support point distance, and can also reduce the material cost of the trolley itself. Yes.

Hereinafter, the present invention will be described with reference to the accompanying drawings, but the present invention is not limited thereto.
In order to solve the above problems, an overhead line structure 1 for a charging station according to the present invention is an overhead line structure provided at an outdoor charging station for charging a storage battery vehicle via a current collector while the vehicle is stopped. Underneath the support body 4, a main body 2 that contacts the electric device, a support structure 3 that supports the main body 2, a support body 4 that extends upward from the support structure 3 so as to be orthogonal to the rail. And a support member 6 that supports the train line main body 2 via the insulator 5. The train wire body 2 is made of a highly conductive metal plate in the form of a strip, and is installed above the rail so as to extend along the rail so that the current collector can contact the lower surface. The support structure 3 is provided on the side of the rail at every predetermined interval in the extension direction of the train line main body 2. The support member 6 includes a pair of hooks 15, a pedestal 13, and a pair of support saddles 14. The pair of hooks 15 are fixed to both surfaces of the upper edge portion of the train line main body 2. The pedestal 13 is fixed to the lower end of the insulator 5. The pair of support saddles 14 are fixed to the lower surface of the pedestal 13 and support the hanging bracket 15. The pair of hanging brackets 15 has an L-shaped cross section and has first and second sides 15a and 15b. The first side 15a is fixed to the side surface of the main body 2 and the second side 15b is a train. The wire body 2 extends laterally from the upper end of the wire body 2 at a right angle. The pair of support saddles 14 have support pieces 14 b, which receive the lower surface of the second side 15 b of the metal fitting 15 and hold the second side 15 b between the base 13.

  In the overhead wire structure 1 of the present invention, the train line main body 2 is made of a highly conductive metal plate in the form of a strip, so there is no risk of snow accumulation on the top. Since the main line 2 is relatively thin and light, material costs can be reduced, and the distance between the support points can be increased (for example, three support points with a maximum distance of 10 m for an overhead wire length of 24 m). Equipment costs can be reduced.

Embodiments of the present invention will be described with reference to the drawings.
The overhead line structure 1 for a charging station is an overhead line structure provided in an outdoor charging station for charging a storage battery vehicle via a current collector while the vehicle is stopped. The overhead wire structure includes a main body 2 that contacts the current collector, a support structure 3 that supports the main body 2, a support 4 that is supported on the base end side by the support structure 3, and under the support 4. And a support member 6 that supports the train line main body 2 via the insulator 5.

  The train wire main body 2 is made of a highly conductive metal plate such as strip-like aluminum, and is extended above the rail so as to extend along the rail so that the current collector can contact the lower surface thereof. When the train line main body 2 is configured by connecting a plurality of unit strip plates 2a and 2b, the adjacent end portions are sandwiched between a pair of seam plates 16 and tightened with bolt nuts 17 as shown in FIG. .

  The support structure 3 is made of, for example, a concrete pillar, and is provided on the side of the rail at every predetermined interval in the extension direction of the train line main body 2.

  The support 4 includes, for example, a horizontal support pipe 7 whose base end is supported by the support structure 3, a pair of parallel vertical pipes 8 that are fixed to a distal end portion of the horizontal support pipe 7 at the upper end and extend vertically, and a vertical support A suspension fitting 9 is provided between the pipes 8. The horizontal support pipe 7 extends upward from the support structure 3 so as to be orthogonal to the rail.

  The suspension fitting 9 includes a pair of suspension legs 10, a horizontal support plate 11 supported by the suspension legs 10, and a roof member 12 thereabove.

  The pair of suspension legs 10 are respectively fixed to the vertical pipes 8 at the upper ends, and extend downward in parallel inside the vertical pipes 8. The support plate 11 is supported horizontally between the lower ends of the suspension legs 10. The roof member 12 has a gable roof-like ridge, is supported between the suspension legs 10 above the support plate 11, and covers the support plate 11 so that snow does not accumulate on the support plate 11. The upper end of the insulator 5 is fixed under the support plate 11.

  The support member 6 includes a pedestal 13, a pair of support saddles 14, and a pair of hooks 15. The pair of hooks 15 are fixed to both surfaces of the upper edge portion of the train line main body 2. The pedestal 13 is a horizontal plate and is fixed to the lower end of the insulator 5. The pair of support saddles 14 are fixed to the lower surfaces on both sides of the pedestal 13 and support the hanging bracket 15. The pair of hanging brackets 15 has an L-shaped cross section and has first and second sides 15a and 15b. The first side 15a is fixed to the side surface of the main body 2 and the second side 15b is a train. The wire body 2 extends laterally from the upper end of the wire body 2 at a right angle.

  Each of the pair of support saddles 14 includes a fixed side 14a fixed to the lower surface of the pedestal 13, and a support piece 14b continuous through a step portion inside the fixed side 14a. The support piece 14 b extends substantially parallel to the lower surface of the pedestal 13 with an interval therebetween, and rests on the lower surface of the second side 15 b of the hanging bracket 15. For example, in the case where the train line main body 2 is supported at the three positions in the middle between the both ends, as shown in FIG. 3A, the second side 15b of the bracket 15 is connected to the support piece 14b and the pedestal 13 at At both ends, the second side 15b of the hanging bracket 15 is not clamped and is supported on the support piece 14b and supported to allow expansion and contraction.

  In this overhead wire structure 1, since the train wire main body 2 is made of a highly conductive metal plate having a strip shape, there is no risk of snow accumulation on the upper part. If necessary, by further reducing the thickness of the upper edge portion of the train line main body 2 toward the upper end, further measures for preventing snow accumulation can be taken. The roof member 12 above the insulator 5 prevents the snow on the support plate 11, the insulator 5 and the support member 6 below. Therefore, there is no possibility of accidents of damage to the vehicle or the current collector due to falling snow. Since the train line main body 2 is relatively thin and lightweight, the material cost can be reduced and the distance between the support points can be increased, so that the equipment cost is reduced.
