Description

[Detailed description of the invention] (Industrial application field) This invention divides multiple cables so that they do not become entangled with each other when laying power or control cables along a cable tray. The present invention relates to an improvement in a guide roller device installed at required locations on a cable tray for guiding.

(Prior Art) In recent years, in order to meet the demand for more efficient cable laying work at power plants, etc., as shown in Figs. It is customary to run the line along the

In this case, the endless pulling rope R is stretched around the guide rollers G along the cable tray T, and is routed by the wire stretching device M.
The plurality of cables C are bundled and tied to the traction rope R, and are simultaneously extended.

(Problems to be solved by the invention) In the conventional cable extension method described above, multiple cables or cables and traction ropes become entangled with each other during the extension process.
There is a problem in that it is necessary to correct this entanglement after the wire is extended.

This invention solves the above-mentioned conventional problems, and can guide the drawing out while dividing the cables or the cable and the traction rope so that they do not get entangled with each other during wire extension work. It is an object of the present invention to provide a guide roller device that allows the cable to be easily taken down from the roller and placed on the cable tray after the cable is wired.

(Means for Solving the Problems) In order to solve the above problems, this invention includes a bracket 1 fixed to one edge of the cable tray T, and a shaft having one end pivotally connected to the bracket 1. 2, and a bearing member 3 which is fixed to the other edge of the cable tray T facing the bracket 1 and has a recess 4a for receiving the other end of the shaft 2.
, a pin 7 which is detachable from the bearing member 3 for closing the recess 4a of the bearing member 3 after the bearing is inserted to prevent the shaft 2 from coming off, and a pin 7 which is rotatably provided on the shaft 2 and extends in its extending direction. A guide roller device was constructed from a roller 8 having a plurality of flanges 8a, 8b, 8c, 8d, and 8e formed at intervals from each other.

(Function) This guide roller device is attached to a required location on the cable tray T so as to cross the cable tray T.

Then, the adjacent collars 8a, 8b, 8c of the roller 8,
The traction rope R and cable C are passed between 8d and 8e to proceed with the wire extension work. The roller 8 rotates and guides the traction rope R and the cable C as they advance. Therefore, each tow rope R and cable C have collars 8a, 8b, 8c, 8
d and 8e, so that they do not intertwine with each other during the wire extension.

After delivering the cable C to the specified section, stop the towing rope R, cut off the required cable C, lower the cable C from the roller R, and move it to the cable tray T.
Place it on top. In this case, from the bearing member 3 to the pin 7
, open the bearing recess 4a, and open the bearing recess 4a.
If the shaft 2 is removed and rotated, the cable tray T is opened, so that the cable C can be lowered from the roller 8 without removing the entire guide roller device. After lowering the cable C, the shaft 2 is again supported by the bearing member 4a in preparation for reuse.

(Embodiment) A bracket 1 is fixed to the inside of one edge of a cable tray T, and one end of a shaft 2 is pivotally connected to this for horizontal rotation. This shaft 2 is designed to be long so that it can be applied to cable trays T of various widths.

The bearing member 3 is fixed to the other edge of the cable tray T so as to face the bracket 1. This bearing member 3 has a horizontal bearing recess 4a.
and a pin insertion hole 4b for closing the bearing recess 4a, and a tightening member 6 which can be tightened with a bolt 5 with the edge of the cable tray T sandwiched therebetween. Consists of.

The retaining pin 7 can be inserted into and removed from the hole 4b of the bearing member 3, and can close the bearing recess 4a and hold the shaft 2 when inserted.

The roller 8 is rotatably supported on the shaft 2, and a plurality of flanges 8a, 8b, 8c, 8d, and 8e are provided on its outer periphery at intervals in the extending direction.

As shown in FIG. 2, a plurality of guide roller devices having the above configuration are provided at required locations on the cable tray T, and each collar 8a, 8b, 8c, 8d,
The traction rope R and cable C are passed between 8e.

Then, the traction rope R is drawn out along the cable tray T by a wire drawing device (not shown) while drawing out the cable C.

As the traction rope R and cable C move forward, the rollers 8 rotate to smoothly guide their progress. When the traction rope R and the cable C pass through the roller 8, they are separated by the collars 8a, 8b, 8c, 8d, and 8e, and are prevented from becoming entangled with each other.

When the cable C has been extended to the specified position, remove the pin 7 of the bearing member 3, open the bearing recess 4a, remove the shaft 2, swing it toward the bracket 1 side, open the cable tray T, and then remove the pin 7 of the bearing member 3. Cable C
from the tow rope R and lower it onto the cable tray T from the open part. After the cable is installed, for further cable extension work, return the shaft 2, insert the pin 7, and move the roller 8 to the cable tray T.
Build it above.

(Effects of the invention) As explained above, in this invention, there is a bracket 1 fixed to one edge of the cable tray T, a shaft 2 whose one end is pivotally connected to the bracket 1, and the bracket 1. a bearing member 3 that is fixed to the other edge of the cable tray T and has a recess 4a that receives the other end of the shaft 2;
, a pin 7 which is detachable from the bearing member 3 for closing the recess 4a of the bearing member 3 after the bearing is inserted to prevent the shaft 2 from coming off, and a pin 7 which is rotatably provided on the shaft 2 and extends in its extending direction. Since the guide roller device for cable extension is constituted by the roller 8 having a plurality of flanges 8a, 8b, 8c, 8d, and 8e formed at intervals from each other, the traction rope R and the cable C
As the tow rope R and cable C pass through the roller 8, the roller 8 rotates and can smoothly guide the progress.
8b, 8c, 8d, and 8e, and mutual entanglement is effectively removed. Therefore, the work of removing entanglements after the wire has been extended can be omitted, and the efficiency of the wire extension work can be greatly improved. In addition, after the cable extension is finished, the cable C is lowered from the roller 8 and the cable tray T
The work of laying the cables on top can be easily done by removing one end of the shaft 2 of the roller 8 and rotating it to open the cable tray T. Since there is no need to remove the entire device, it is ready for the next use immediately. It has the following effects.
