Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an installation device used to install a cable rack.

The conveyor 2 shown in FIG. 1 operates by receiving electric power from the electrical room 1 via a power supply cable.

This power supply cable is passed through the underground cable pit 4 so as not to cause any other damage.

Then, the power supply cable is installed so as to be supported on the cable rack 8 shown in FIG. 2 or the cable rank 3 on the conveyor side.

This cable pit 4 is covered with a lid 5 to eliminate the danger of traffic.

The cable rack 8 is installed on support metal fittings 6 protruding from both side walls of the cable pit 4, and a power supply cable can be mounted on the cable rank 8.

Conventionally, the work of installing the cable rack 8 on the support fitting 6 has been done manually inside the cable pit 4, which has been laborious and involves danger when transporting the cable rack.

An object of the present invention is to provide an installation device for safely and easily installing a cable rack.

An embodiment of the present invention will be described below with reference to FIGS. 2, 3, and 4.

The traveling trolley 13, which has a width smaller than the width of the passage in the cable pit 4, is made up of a traveling frame supported by traveling rollers 15, and this traveling frame is provided with four vertical guide columns. There is.

As shown in FIG. 4, a vertical portion of a T-shaped pedestal 9 is housed inside the guide column so as to be slidable up and down.

This T-shaped pedestal 9 has a lower frame 12 as shown in FIG.
and an upper frame 16 that covers this lower frame 12,
Arms 1 project horizontally from this upper frame 16 to both sides.
7, a guide roller 11 mounted on an arm 17 for free rotation, and a coil spring 10 provided between the upper and lower frames 12 and 16.

In particular, the arms 17 are bifurcated with two protruding from the upper frame 16 on each side.

The lower end of the pedestal 9 is supported from the traveling carriage 13 by a pantograph type jack 14, as shown in FIG.

In this embodiment, during the cable rack installation work, the traveling rollers 15 are suspended by a crane so as to land on the bottom surface of the TF cable pit 4.

Thereafter, the handle of the jack 14 is operated to jack up the gantry 9 so that the arm 17 and the guide roller 11 are at a higher position than the support fitting 6.

Next, the cable rack 8 prepared on the ground is lifted up by a crane and placed on the guide rollers 11.

If the cable rack 8 is long, the cable rack 8
A plurality of installation devices consisting of frames 9, traveling carts 13, etc. are included in the cable pit 4 so that the cable can be supported at multiple points.

Once the cable rack 8 is received on the guide roller 11, the traveling carriage 13 is moved to the installation position of the cable rack 8.

When the vehicle is running, the arm 17 is jacked up to a position higher than the support metal fitting 6, so that the support metal fitting 6 does not become an obstacle to running.

After carrying the cable rack 8 to the installation position, attach the pedestal 9
With a worker on top, the coil spring 10 is compressed by applying the worker's own weight, and the pedestal 9 is mounted, and the cable rack 8 is mounted on the support metal fitting 6.
Let it sink until it touches.

In this submerged state, the combined positional relationship between the support fitting 6 and the cable rack 8 is confirmed.

If the combination positions do not match, they can be adjusted by moving the traveling carriage 13 or adjusting the cable rack 8 on the guide roller 11.

If it fits, lower the pedestal 9 by operating the handle of the jack 14, and move the cable rack 8 from the pedestal 9 to the support fitting 6 side.
Replace and fix.

Thereafter, the pedestal 9 is further lowered so that the arm 17 and the guide roller 11 are positioned below the support fitting 6.

Once in this lowered position, the traveling carriage 13 is caused to travel toward its original position.

Thereafter, the arm 17 and the guide roller 11 are jacked up to a position above the support fitting 6, and the installation work of the next cable rack begins.

Once all the cable racks are installed, the traveling trolley 13
is rotated to direct the arm 17 in the longitudinal direction of the cable pit 4.

Thereafter, the traveling carriage 13 is lifted upward through the width of the passageway and left by a crane.

This embodiment has the advantage that the coil spring 10 also functions as a shock absorber when the cable rack 8 is received on the frame 9.

As described above, according to the present invention, operations such as transporting the cable rack, adjusting and moving the cable rack, which are necessary for cable rack installation work, can be performed without supporting the cable rack manually, and it is also possible to install the cable rack by lifting it with a crane. Compared to this, the cable rack does not wobble or fall off, so the cable rack can be installed safely and effortlessly.
