Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cable laying guide device for laying a cable in a trough within a tunnel.

Conventionally, cable guide devices have been widely used to lay cables in tunnels.

This guide device has a roller rotatably supported on a pair of brackets, and is installed on the cable laying route in the tunnel.
The cable is placed on the rollers and run, and the cable is drawn into the tunnel and laid.

Since such a guide device is installed on the floor of a sinus canal and draws the cable into the sinus, the cable must be lifted onto the trough after the cable is pulled into the sinus.

Lifting this cable onto the trough is difficult and requires a lot of effort.

This is particularly difficult when the cable is large or the trough is located at a high position.

In view of these points, the present invention aims to solve the above-mentioned drawbacks by providing a guide device for cable laying that allows cables to be drawn along a trough in a tunnel, and after being drawn in, to be laid within the trough as is. It is something to do.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.

1 is a trough placed in the tunnel; 2 is a cross-sectional support fitting; one end is fixed to a side wall or support 3 in the tunnel;
It supports the trough 1.

The bearing 4 is a roller, which is rotatably supported by a pair of bearing members 5.

The roller 4 of the receiver has a drum-shaped concave surface,
This is preferable because the contact surface with cable C matches.

The bearing member 5 is fixed to opposing side plates 6, 6.

The bearing member 5 and the side plate 6 may be formed as an integral member as shown in the drawings, or may be formed as separate members.

The side plate 6 is fixed and erected on a base plate 7, and the base plate 7 is fixed on a rising portion 8a of an L-shaped support member 8.

The support member 8 has its lower side portion 8b inserted into the cross-sectional shape of the support metal fitting 2, and is detachable from the support metal fitting 2.

An appropriate number of holes 9 are formed in parallel on the side surface of the lower side 8b of the support member 8, and holes 2a are formed on the side surface of the support metal fitting 2, so that the holes 9 and 2a are connected to each other. When they match, the pin 10 can be inserted and fixed at the same position.

The reason why a suitable number of holes 9 are arranged in parallel on the lower side 8b of the support member 8 is that the position of the roller 4 on the trough 1 can be adjusted by the receiver depending on the degree of insertion of the lower side 8b into the support fitting 2. This is to ensure that.

That is, if the lower side part 8b of the support member 8 is inserted less, the position of the roller 4 will be in front of the trough 1, and if it is inserted more, the position of the roller 4 will be in the back of the trough 1. Depending on where on the trough 1 the cable C is laid, the receiver adjusts the position of the roller 4 to the position where the cable falls, and the receiver reduces the distance the cable C has to be moved from the roller 4 so that it simply falls onto the trough 1. This is because it can be installed using

Reference numeral 11 denotes a guide roller, and a receiver prevents the cable C on the roller 4 from falling during retraction.

The guide roller 11 is rotatably provided by having its support shaft removably inserted into a mounting hole of a mounting member 12 fixed to the side plate 6.

Note that 13 is a reinforcing member for the base plate 7.

With this cable installation guide device, the cable C
To install the cable in the trough 1, first, the cable installation guide device according to the present invention (hereinafter referred to as the device according to the present invention) is attached to the support member 8 of the support fitting 2 of the trough 1. , installed at appropriate intervals.

After that, the cable C is placed on the roller 4 of the device according to the present invention, and the cable C is drawn in. The cable C is then dropped from above the roller 4 into the trough 1 and laid (see Fig. 1). .

At this time, depending on where in the trough 1 the cable is laid, the degree of insertion of the lower side 8b of the support member 8 is adjusted, and the position of the roller 4 is adjusted in advance so that the receiver is in the depressed position. Since it is a mating cable, dropping the cable C will take you to the installation position.

Once the installation is complete, remove the proposed device.

Incidentally, it is preferable that the roller 4 of the receiver is an electric roller because the cable C can be pulled in even more easily.

As described above, the present invention is detachable from the support fitting 2 of the trough 1, and when attached to the support fitting 2, the roller 4 of the receiver is located near the upper part of the trough 1, so that the cable can be attached to the trough 1. The receiver can pull in the roller 4 along the
The cable that has been drawn in can be laid by simply dropping the receiver onto the roller 4, so that the laying work can be easily carried out without requiring any time or effort.

Moreover, since the position of the roller 4 can be adjusted on the trough 1 depending on the cable installation position, the position where the cable is dropped can also be determined.

In particular, if the roller 4 of the receiver is an electric roller, it will be easier to pull in the cable.
