Description

Technical Field

[0001] The present invention relates to a cable receiving object configured to be able to place a cable.

Background Art

[0002] Cables such as power CV cables (cables with cross-linked polyethylene insulation and vinyl sheath) expand and contract due to thermal expansion during energization. Therefore, in consideration of the expansion and contraction of the cable, a snake laying method in which the cable is laid while being serpentined may be adopted.

[0003] In the snake laying method, generally, a cable in which three-phase coils are stacked is often supported by a plurality of cable receiving objects arranged at a predetermined interval, for example, an interval of about 3 m to about 7.� m. The cable receiving object is attached to a standing object or the like.

[0004] As an example of such a cable receiving object, one and the other fixing parts that are respectively in surface contact with one side surface and the other side surface of the standing part of the standing object, a support rod (arm) formed in a rectangular parallelepiped shape, and one and the other cable support members (dishes) respectively fixed to one side and the other side of this support rod, and one and the other rubber plates respectively attached to the upper surfaces of one and the other cable support members. The base end of the support rod is fixed between one and the other fixing parts, the upper surfaces of one and the other cable support members are located slightly above the upper surface of the support rod, and a power cable is laid on one and the other rubber plates. A cable receiving object can be mentioned (for example, refer to Patent Document 1).

Summary of the Invention

[0006] However, the receiving trays of cable support fittings are sometimes made of cast aluminum, which increases the weight of the cable support fitting. In the example of the cable support fitting described above, the arm and receiving tray are fixed together by welding or other means and transported to the cable laying site as an assembly. Such receiving trays and assemblies are difficult to stack and are large in size and weight. As a result, the receiving trays and assemblies are difficult to transport, reducing the efficiency of cable laying work.

The outer circumference of the support column 1 is formed in a roughly cylindrical shape. However, the support column is not limited to this. For example, the support column can be configured to have a flat plate extending approximately parallel to the vertical direction. Examples of support columns having a flat plate include L-shaped steel (angle steel), T-shaped steel, H-shaped steel, etc. In this case, the flat plate of the support column can be configured as a mounting plate, and the cable receiving hardware can be configured without a support mounting device.

[0028] "Details of the support mounting hardware" Referring to Figures 1-4, the support mounting bracket 20 can be configured in detail as follows. Hereinafter, one of the two support mounting members 22, 23 will be referred to as the first support mounting member 22, and the other of the two support mounting members 22, 23 will be referred to as the second support mounting member 23, as necessary. Each support mounting member 22, 23 can be made of steel. However, the material of the support mounting members is not limited to this.

[0029] The support portions 22b and 23b are formed to correspond to a part of the outer circumference of the support column 1. Each support mounting member 22 and 23 has two support fastening portions 22a and 23a, respectively, which are positioned at both ends of the support portions 22b and 23b in the circumferential direction of the support column 1.

[0033] As shown in Figure 4, in each connecting member 31, the arm support portion 31c is formed to correspond to a part of the outer circumference of the rear end portion 41a of the arm body 41. When the two connecting members 31 are combined, these arm support portions 31c are formed to correspond to the outer circumference shape of the rear end portion 41a of the arm body 41. The arm support portion 31c abuts against the rear end portion 41a of the arm body 41. As shown in Figure 1, when the arm 40 is installed at an inclination angle α1 with respect to the horizontal direction, the arm support portion 31c of each connecting member 31 is positioned to be inclined at an inclination angle α1 with respect to the horizontal direction.

[0034] As shown in Figures 1 to 4, each connecting member 31 has two fastening portions 31a and 31b, respectively, which are located at both ends of the arm support portion 31c in the circumferential direction of the arm body 41, namely the first fastening portion 31a and the second fastening portion 31b.

[0035] In such a connector 30, the arm support portions 31c of the two connecting members 31 abut against the outer circumference of the rear end portion 41a of the arm body 41 and are fastened by fastening means F2, and the first and second fastening portions 31a and 31b of one of the two connecting members 31 sandwich the mounting plate 21 with the first and second fastening portions 31a and 31b of the other of the two connecting members 31 and are fastened by fastening means F3, thereby attaching the connector 30 to the mounting plate 21 and the arm 40.

[0036] "Arm details" Referring to Figures 1-4, the arm 40 can be configured in detail as follows. In the following, the longitudinal direction, height direction, and width direction of the arm 40 substantially coincide with the longitudinal direction, height direction, and width direction of the arm body 41 and the receiving plate 50.

The two receiving trays 50 are formed substantially symmetrically with respect to the arm body 41 in the width direction of the arm body 41. The receiving trays 50 may be manufactured by extrusion molding along their longitudinal direction. The receiving trays 50 may also be made of an aluminum alloy. However, the method and material of manufacturing the receiving trays are not limited thereto.

[0042] As shown in Figure 3, the receiving tray 50 is formed to extend from the arm 40 in the width direction of the arm 40, intersecting the longitudinal direction of the arm 40. The tip 50a of the receiving tray 50 in the direction of extension is formed to curve toward the bottom side in the height direction of the receiving tray 50. This tip 50a of the receiving tray 50 functions as a handle during transport and contributes to the protection of the cable C. The direction of extension of the receiving tray 50 is approximately the same as the width direction of the receiving tray 50.

[0043] The top of the receiving tray 50 is positioned slightly above the top of the arm body 41 in the vertical direction. The receiving tray 50 is formed so that its height decreases from its base end 50b to its tip end 50a in the direction of its extension. The top of the receiving tray 50 in the height direction is formed in a corrugated shape with a plurality of substantially parallel small grooves to improve adhesion with the receiving tray cover member 61, which will be described later.
