Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotating cable conveying device that conveys cables and hoses while rotating around a circular rail installed in a circular room of a building.

This type of rotating cable conveyance device that has already been proposed is
As shown in Figures 1 to 4, circular room b of building a
A rail platform c is horizontally extended within the interior, a circular rail d is installed on the rail platform c, and a rotating truck e is provided on the circular rail d so as to be able to travel via wheels e. stand c
Each holder f is provided on the inner circumferential wall of the circular chamber b located below the holder f, and an outer guide g having a substantially L-shaped cross section and an arc shape is fixed on each holder f. Swivel trolley e
An inner guide i is installed at the lower part of the machine via a plurality of support punches h to the position of the outer guide g, and this inner guide i can be rotated about 360 degrees together with the rotating cart e. , fixed ends i,,k, of a pair of upper and lower chains i, k constituting the cable conveyance device 1 are fixed to one end g, of the outer guide g, and each chain i, k is moved. Attach the ends i2 and k2 to one end i of the inner guide i (see Figures 3 and 4), and then attach each cable insertion plate 1 to each ring of each chain j and k. established,
Each cable m of a predetermined length is passed through each insertion hole 1 of each cable insertion plate 1, and each caster n is brought into contact with the inner and outer guides g and i on the lower surface of the chain k. The chains i, k' and the low hooves o, o2 are provided so as to fit against the inner and outer guides g and i.

Therefore, in advance, each cable insertion plate 1 as the cable conveying device 1 and each cable m are inserted and temporarily fixed to the
Next, by turning the turning cart e to the right or left, each cable m is rotated as shown in FIGS. 3 and 4.
The cable conveying device 1 holding the cable can be rotated and moved to a desired position.

However, each chain i of the cable conveying device 1
, k are the turning limits A, as shown by the chain lines in FIG.
It will be in state B.

That is, from the state where each of the chains i and k are at the turning limit A,
When the inner guide i is turned to the left, or when the chains j and k are trying to turn the inner guide i to the right from the turning limit B, the turning force of the inner guide causes Not only is there a risk that the casters n supporting each chain j and k may come off the path of the inner and outer guides g and i, but also the entire cable conveying device 1 may fall down, as shown by the chain lines in FIG. The present invention
In view of the above-mentioned points, the present invention has been made so that cables, etc. can be smoothly transferred to predetermined positions without each caster coming off from the inner and outer guides even when the rotating cart makes a large turn on the circular rail. The present invention provides a rotating cable conveying device for the purpose of.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An illustrated example in which the present invention is applied to a cable conveyance device in a nuclear reactor will be described below.

In FIGS. 5 to 11, reference numeral 1 denotes a building housing a nuclear reactor, for example, and a circular chamber 2 is provided in this building 1. The inner peripheral wall 2a of this circular chamber 2 has various rails. Tables 3 are horizontally extended at regular pitch intervals.
Furthermore, “a circular rail 4 is installed on the above-mentioned rail platform 3,
A rotating truck 5 having wheels 5a is provided on the circular rail 4 so as to be able to run thereon. Further, a locking member 6 is provided as a shield on the rotating carriage 5, and a stopper 7 is provided on the inner circumferential wall 2a on the movement path of the locking member 6 to prevent the rotating carriage 5 from rotating more than one rotation. It has been extended to . On the other hand, as shown in FIG. 8, support villages 8 having a channel-shaped cross section are provided on the rotating truck 5 at a constant pitch interval. An inner guide 9 is provided.

Further, on the inner peripheral wall 2a of the circular chamber 2 where the inner guide 9 is located, an outer guide 10 in the shape of a ring plate and an arc-shaped regulating plate 11 are fixed with a pedestal 12. A part 10a of the outer guide 10 is provided with a starting end 1 of a pair of upper and lower chains 13 and 14 as the cable conveyance device 1.
3a, 14a are fixed, and each chain 13,
The terminal ends 13b, 14b of 14 are attached to a part of the inner guide 9 (see FIG. 6). Furthermore, each cable insertion plate 15 is provided on each link constituting each of the chains 13 and 14 so as to connect both chains 13 and 14, and each cable insertion plate 15 is inserted into each link. Each cable 16 is inserted through the hole 15a.Furthermore, each caster 17 is connected to the inner and outer guides 9, 1 on the lower surface of the chain 14.
Each of the chains 13 and 14 is provided with rollers 18 and 19 so as to be in rolling contact with the side walls of the inner and outer guides 9 and 10. . Moreover, on one side of each cable insertion plate 15,
As shown in FIGS. 6 and 9, each support plate 20 is attached in the vertical direction, and each roller 21 is mounted on a support shaft 22 of the rotating truck 5 on which each support plate 20 is located. It is provided so that it can come into contact with each of the above-mentioned Fuji boards 20 via. Therefore, now, each cable 16 is inserted into each cable insertion plate 15 as the cable conveying device 1 and temporarily fixed, and then the above-mentioned turning cart 5 is turned to the right or left, as shown in FIG. As shown in FIG. 8, the cable conveying device 1 holding each cable 16 can be smoothly rotated by the arc-shaped regulating plate 11, each supporting surface 20 of each insertion plate 15, etc., and can be moved to a desired position. It looks like this.

That is, each of the rollers 21 provided on the support shaft 22 of the rotating truck 5 comes into contact with each of the support plates 201 to regulate the position of the cable conveying device 1 to prevent it from falling down, and also to prevent each of the rollers 21 from falling down. The cable conveying device 1 is kept in balance by coming into contact with the arc-shaped regulating plate 11. Furthermore, the two contact plates are brought into contact with each other at the inner and outer guides 9 and 10 near the reversed portions of the chains 13 and 14, as shown by the chain lines in FIG. , so each caster 17 is connected to the inner and outer guides 9,
There is no risk of them dropping out of the top 10. As described above, according to the present invention, the rotating carriage 5 is provided on the circular rail 4 of the circular chamber 2, and the inner guide 9 is mounted on the rotating carriage 5, and the plurality of supporting villages 8
The outer guide 10 and the arc-shaped regulating plate 1 are provided on the inner circumferential wall 2a of the circular chamber 2 where the inner guide 9 is located.
1, and this outer guide 10 and inner guide 9.
A pair of upper and lower chains 13 having a length of approximately half a circumference between them
. Since rollers 21 are attached to the support shafts 22 of the rotating cart 5 and can come into contact with each support plate 201, the cables 16 inserted into the cable insertion plates 15 do not fall down due to their own weight. , there is no fear of it coming off the inner and outer guides 9 and 10, and not only smooth operation is possible, but also the structure is simple, so it can be easily incorporated into existing equipment.
