Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mount for a cable delivery device, and more particularly to a mount for a cable delivery device suitable as a mount for a device that continuously sends out cables within a tunnel.

Conventionally, when laying a cable in a tunnel, as described in Japanese Patent Publication No. 44-19309, an appropriate cable sending device is installed at the cable sending point, that is, the cable drum arrangement point, and A construction method is adopted in which a winch is installed on the side, the cable is sent out by a sending device, and the traction wire connected to the tip of the cable is pulled by the winch.

However, in such a construction method, when the length of the cable is long, it becomes impossible to lay the cable within the permissible tension, and the length of one cable to be laid is limited.

On the other hand, the cable delivery device, for example,
As described in Japanese Patent No. 5, there is a means for installing cables at several locations along a cable laying line in a tunnel so that one cable is sequentially sent out by a plurality of sending devices.

In order to implement such means, the cable laying height may vary depending on the surrounding circumstances within the tunnel, and the cable delivery device may have to be installed at a location considerably higher than the floor level.

However, conventionally, there has been no suitable mount for the cable sending device, and the turret and the like must be assembled each time, making the preparation and assembly work complicated.

An object of the present invention is to provide a mount for a cable delivery device that is easy to transport and store.

Another object of the present invention is to provide a height-adjustable stand for a cable delivery device.

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

FIG. 1 shows an embodiment of the present invention.

In the figure, a pedestal 1 according to the present invention includes a frame 3 having a size on which a cable delivery device 2 can be placed, and extendable and retractable support legs 4 provided at the outer edge of the frame 3.

The frame body 4 is constructed as shown in FIGS. 2 and 3.

That is, it is made of shaped steel and assembled into a rectangular shape with a size corresponding to the shape of the cable delivery device 2 to be supported, and a presser metal fitting 5 for holding down the cable delivery device 2 is provided at the outer edge.

The presser metal fitting 5 attaches a hook portion 7 to a pin 6 planted on the side surface of the frame body 3.
A clasp 8 having a clasp 8 is rotatably supported.

Although not shown, a mechanism for hooking the hook 7 to the base of the cable delivery device 2 is provided in correspondence with the presser fitting 5, and by rotating the clasp 8, the cable delivery device 2 is attached to the frame 3. It is designed to be easily fixed.

A hook 9 is fixed to the side surface of the frame 3.

The support leg 4 has a plurality of unit rods 12 each having a threaded portion 10 at one end and a matching female threaded portion 11 at the other end, each of which is connected in a screw-type manner in a detachable manner. The length is adjustable.

Further, the support legs 4 are locked to the frame body 3 in the following manner.

That is, a support cylinder 14 equipped with a lock nut 13 is fixed to the outer surface of the frame with a presser band 15, a unit rod 12 is removably inserted into this support cylinder 14, and the lock nut 1 is
It is fixed by tightening with 3.

The lock nut 13 is fixed to the lower end of the support tube 14 with a pin 16, and by tightening the pressure nut 17, an internal wedge 18 is pressed against the unit rod 12, thereby fixing the support tube 14 and the unit rod 12. It is something.

When the pedestal 1 constructed as described above is used, it is assembled in a tunnel etc. as shown in FIG. 1, but at this time,
The number of joints of the unit rods 12 is appropriately selected so that the installation position of the cable delivery device 2 is at the optimum height, the amount of insertion of the unit rods 12 inserted into the support tube 14 is adjusted as appropriate, and the lock nuts 13 are tightened. Make fine adjustments by doing this.

In addition, a hook 9 provided on the frame 3 to fix the entire mount 1 in the installation position and a hook 1 provided in the tunnel etc.
A fixing wire 21 having a turnbuckle 20 is passed between the fixing wire 9 and the fixing wire 21 to fix the frame body 3.

The cable delivery device 2 placed on the frame 3 is fixed by a presser fitting 5 so as not to move when the cable 22 is sent out.

FIG. 4 shows another embodiment of the invention.

This embodiment differs from the embodiments shown in FIGS. 2 and 3 in the structure of the support legs, and common parts are given the same reference numerals.

That is, the support leg 4 in this embodiment has a plurality of metal pipes 23A, 23B, and 23C having different diameters inserted and removed in sequence, and between the adjacent metal pipes 23A and 23B,
The space between 23B and 23C can be drained with a lock nut 24.25 having the same structure as that shown in FIG.

Therefore, by loosening the lock nuts 24 and 25, the length can be adjusted steplessly by adjusting the amount of insertion between the metal pipes.

The support leg 4 is constructed by using the same means as shown in FIG. It is fixed by tightening with a lock nut 13.

Further, a connecting rod 26 is stretched between the supporting legs 4 to maintain a spacing as necessary for reinforcement.

As described above, the cable sending device mount according to the present invention is easy to transport and store because the frame body and supporting legs can be separated to make it smaller and lighter, and it is especially easy to transport and install even in narrow places such as inside a tunnel. I can do it.

Furthermore, since the supporting legs are extendable and retractable, the installation height of the cable delivery device can be adjusted.
