BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving member for a connecting portion of an underground cable in a CV cable mode which is relatively maintenance free.

[0002]

2. Description of the Related Art Recently, underground lines have been widely used for power transmission in public areas such as public ditch (cave) in urban areas. In this case, the underground cable is also changing from the use of the old OF cable to the CV cable which requires relatively little maintenance. However, at the cable connection point of the CV cable, a large-scale special insulation connection device having a heating pot structure for welding insulating resin must be used,
Due to this, special consideration must be given to the supporting metal at this connection position. However, the underground cable (O
The receiving material (support metal fitting) of the F cable is simply a combination of a support arm portion of a fixed length protruding from the wall surface side and a support metal fitting on which the cable is placed. In order to manage the underground cable as much as possible along the wall surface (for example, at a position separated by 30 cm from the wall surface), the protruding length of the supporting arm portion is inevitably limited.

[0003]

However, when connecting a large-capacity CV cable as described above, a special connecting device has to be attached to the connecting point of the cable.
As in the conventional case, a mere fixed type support bracket cannot provide a predetermined working space because the space between the cable and the wall is limited, and the connecting device cannot be used in this state. Therefore, until now, a separate connection work support stand was once assembled at the tip of the fixed type support bracket (position near the wall surface), the cable was guided on the support stand to perform a predetermined connection process, and the support was made after connection. It is necessary to move the cable from the stand position to the fixed type support bracket by lifting the cable, which complicates the connection work. For this reason, the development of new support fittings that can be dealt with before and after connection work is awaited.

In view of the above situation, the present invention allows a receiving plate portion having a receiving body for directly receiving a cable to be pushed out to a forward position (front side) so that a worker can insert it between the cable and the wall surface at the time of connection work. It is an object of the present invention to provide a receiving material for a connecting portion of an underground cable which solves the above problems by obtaining a space.

[0005]

According to the present invention, a pair of plate-shaped supporting arms for fixing a base end to a wall side are provided with a sliding long hole having an upward slant toward a distal end and are supported in the sliding long hole. While penetrating two supporting bolts laterally projecting on the slide receiving plate portion interposed between the arms, the supporting bolts move in the sliding long holes to allow the receiving plate portion to be pushed out to the tip end. A receiving body having a cable receiving groove is placed on the upper portion of the receiving plate portion.

[0006]

With the above-mentioned structure, the support plate slidably mounted on the support arm which is fixed during the cable connection work, and the support bolt projecting from the support plate are slid on the support arm. If the sliding long hole moves forward (toward this side) along the moving elongated hole, the sliding long hole has an inclination inclined upward, so that the receiving plate portion guided by the sliding long hole moves forward and moves upward. Will be pushed out. If the support bolt is tightened at the end position of the sliding long hole, the receiving plate is fixed at that position, and the cable placed on the receiving body of the receiving plate is separated from the wall surface by the amount of movement of the sliding long hole and connected. Space required for work can be taken. After the connection work, reversely from the above, push back the receiving plate part on which the cable is placed to the base end side, and the supporting bolt of the receiving plate part is lowered and guided in the slidable long hole, so it can be easily specified. Return to the cable support position.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings of the embodiments.

The drawing shows a receiving member for a connecting portion using a CV cable in a cavernous hole, where 1 is a pair of fixing bases with mounting bolts 3 to a metal plate 2 fixed to a wall surface A'of the cavernous hole A. Of the plate-like support arm, each of which is provided with a slidable long hole 4 inclined in the longitudinal direction toward the upper end of the support arm 1, and one piece is provided in the gap 1a of the opposing support arm 1, 1. The slide receiving plate portion 5 is fitted, and the two bolt holes 6 bored at a predetermined distance in the base of the receiving plate portion 5 and the sliding long hole 4 of the support arm 1 are aligned with each other. While having a slide structure that penetrates the book support bolt 7 and sandwiches the receiving plate portion 5,
An insulator receiver 9 having an orthogonal cable receiving groove 8 formed in the upper portion 5a for mounting the receiving plate portion 5 protruding from the upper edge of the support arm 1 is formed at the center of the lower end longitudinal direction. Guide groove 1 provided
A so-called horse-riding set in which 0 is inserted is used, and the receiving portion 11 for the connecting portion of the underground cable is formed with the entire configuration thereof. in this case,
The front-rear positional relationship between the two support bolts 7, 7 is an inclination arrangement equivalent to the inclination of the sliding long hole 4 of the support arm 1.

Next, this operation will be described. First, when using the receiving member 11 for the connecting portion of the underground cable which is arranged so as to project from the wall surface A'side of the human hole portion A, a cable which is a connecting work step of the cable C is firstly performed. In laying in and carrying in, the setting position of the receiving body 9 of the receiving object 11 is set slightly outside the predetermined cable supporting position (to the wall surface A ′) in advance due to the mounting and connecting work of the special insulation connecting device (not shown). It must be supported away from this side. To this end, the connection receiving member 11
The receiving plate portion 5 provided with the receiving body 9 is placed by sliding it to the outside by a predetermined length in advance. That is, the movement of the slide receiving plate portion 5 fitted between the pair of two supporting arms 1 and 1 whose base ends are fixed to the wall surface A'side is such that the slide receiving plate portion 5 moves laterally through the base portion of the receiving plate portion 5.
Loosen the nuts 7a, 7a to move the supporting bolts 7, 7 in the sliding long holes 4, 4 of the supporting arms 1, 1 and, when reaching the front hole ends 4a, 4a, remove the nuts 7a, 7a. If tightened, it will be fixed in that position. In this case, the support arm 1,
Since the sliding long holes 4 and 4 of 1 are inclined toward the upper end of the slide, they move upward as the receiving body 9 integrated with the sliding receiving plate portion 5 is fed out (see FIG. 3).

In this way, in the receiving body 9 above the receiving plate portion 5 which is extended forward with respect to the support arm 1, the human body portion A from the sinusway B is inserted.
When the cable C pulled in is placed, since the receiving body 9 of the cable C has moved (protruded) to the tip position of the receiving plate portion 5, a predetermined space can be taken with respect to the wall surface A ′. Therefore, the special insulation connection device (not shown) set on the cable C can be mounted without contacting the wall surface A ', and a predetermined connection work may be performed.

Next, after the connection work is completed, the receiving plate portion 5 may be returned to the original supporting position. First, after removing the special insulation connection device, the cable C that has been extended to the other side in advance.
The support bolts 7, 7 fixing the receiving plate 5 with the receiving body 9 loosened the nuts 7a, 7a of the support bolts 7, 7,
Along the sliding long holes 4 and 4 of the support arm 1, 1
By moving to b, 4b, since the sliding long holes 4, 4 are inclined downward, the receiving plate portion 5 returns to the base end side of the supporting arm members 1, 1 by the sliding movement, and the nuts 7a, 7a are moved. It will be fixed if tightened. In this case, even if the cable C that has undergone the connecting step has a slightly larger diameter and becomes heavier due to installation of an insulating member, etc., the sliding elongated holes 4 and 4 of the supporting armrests 1 and 1 are inclined downward during the returning work, so that the cable C is separately provided. Even if the tool or the like is not used, the operator simply applies a small pressing force, and the supporting bolts 7, 7 slide down in the sliding long holes 4, 4 so that the supporting bolts 7, 7 move smoothly to the original supporting position.

Incidentally, the sliding long holes 4 of the supporting arms 1, 1
4 is the position where the receiving plate portion 5 has returned to the base ends of the supporting arms 1 and 1, and the hole end 4 that is the tip portion of the sliding long holes 4 and 4.
Since a and 4a are set to be slightly longer than the tip edge of the receiving plate portion 5, when the receiving plate portion 5 returns to the base ends of the supporting arm members 1 and 1, the tips of the sliding long holes 4 and 4 are A stopper bolt 12, which is used as a separate stopper pin, can be inserted into the hole ends 4a, 4a, and together with the tightening of the support bolts 7, 7, secures the receiving plate portion 5 (see FIG. 1). (See dashed line).

[0013]

As described above, the receiving member for the connecting portion of the underground cable according to the present invention has the sliding receiving plate portion having the receiving body for directly receiving the cable, and the sliding support armature fixed to the wall surface side. Since it is slid by the support bolt that guides it into the moving long hole and can be pushed out to the tip side, when using a metal receiving object during cable connection work, simply push out the receiving plate to the tip side A large space can be obtained, and there is no hindrance to the entry and exit of the worker on the wall surface side or the installation of a special insulation connection device that serves as a cable connection device. In addition, the cable support after the connection work is simply returned to the base of the support arm along the sliding long hole by simply returning the receiving plate part that has been extended to the close side to the wall surface similar to the conventional cable support. Can be set to position. Moreover, in this returning operation, since the sliding long hole is inclined downward toward the wall surface, the cable can be easily slid back to the predetermined supporting position without using a special tool when pushing back the cable, and workability is good. Therefore, it is not necessary to separately assemble a support base for connection work or remove it after connection work. Further, since the present invention has a simplified structure, it is easy to manufacture, can be provided at low cost, and has practical effects such as failure and damage during use.
