Description

[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to a mount for a cable delivery device, and particularly to a mount for a cable delivery device suitable as a mount for a device that continuously sends out cables in a tunnel.

(Technical background of the invention and its problems) Conventionally, when laying a cable in a tunnel, as described in Japanese Patent Publication No. 44-1.9309, at the cable delivery point, that is, at the cable drum arrangement point, The construction method is to install an appropriate cable delivery device, install a winch at the opposite end of the laid line, send out the cable with the delivery device, and pull the traction wire connected to the tip of the cable with the winch.

However, when using this construction method, it becomes impossible to lay the cable within the permissible tension when the cable is long, and the length of each cable that can be laid is limited.

For example, the cable sending device was developed in 1800.
As described in Japanese Patent No. 25, there is a means for installing cables at several locations along a cable laying line in a tunnel, and sequentially sending out one cable using 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.

(Purpose of the invention) An object of the invention is to provide a stand for a cable delivery device that is easy to transport and store.

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

(Example of idea) The present invention will now be described with reference to the 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 bed 3 that supports a cable delivery device 2, a plurality of adjustable spacers 4, 44 on which the bed 3 is separably placed, and a base that supports the lowest adjustable spacer 4. Consists of 5.

The bed 3 is constructed as shown in FIGS. 2 and 3.

That is, a frame 6 of a size corresponding to the shape of the cable delivery device 2 to be supported is made of shaped steel, and lock pins 7 and hooks 8 are provided at four locations on the outer edge of this frame 6. .

A partially enlarged perspective view of the frame 60 of the head shown in FIG. 2 is shown within the circle A.

This frame body 6 is made of a cylindrical section steel 61 with a square cross section, and a strip 62 whose inner circumferential side is chamfered is welded to the upper surface.

The lock pin I is a threaded rod to which a bundle 9 is fixed at one end, and is screwed into and removed from a cylinder 11 fixed at the top of a plate 10 that projects upward from the upper surface of the frame 6. .

The other lock pins are similarly constructed.

The hook 8 is fixed to the frame 6 so as to protrude laterally from the frame 6.

Circle B part U) A perspective view is shown in circle B'.

Here, the plate 10 and the hook 8 are fixed to the frame 6 via an L-shaped fitting 63.

The bottom of the L-shaped fitting has a recess 631 as shown inside the circle.
is provided, and a convex portion on the upper surface of the adjustment spacer, which will be described later, fits therein.

As mentioned above, the upper surface of the frame 6 is provided with a step that matches the bottom surface of the cable delivery device 2, so that the installation of the device can be done to clarify the position and to increase the stability after installation. I have to.

In the circle d, the bottom surface of the delivery device placed on the diagonally shaded area C in FIG. 2 is shown.

A frame-shaped stepped portion 202 is provided on the bottom surface 201 of the delivery device, and the inner periphery of the frame body 60 and the strip members 62 are aligned with each other.

Further, a metal fitting 204 for receiving the tip of the lock pin 7 is attached to the side surface 203.

Place the delivery device 2 on the frame 6, fit the frame-like stepped portion 202 into the inner circumference of each village 62, and then turn the handles 9 at four locations and screw the tip of the lock pin 7 into the metal fitting 203. Fixation of the device is completed.

The adjustment spacer 4 is constructed as shown in FIGS. 4 and 5.

That is, the shape steel is formed into a truncated cone-shaped box with an opening at the bottom surface 12, and recesses 13 and protrusions 14 that can fit into the recesses 13 are provided at fixed positions on the upper and lower surfaces, respectively.

This adjustment spacer is the circle or circle E in Figure 5.
It is assembled by combining and welding cross-sectional steel sections as shown in '.

The recesses 13 and protrusions 14 are formed by stacking a plurality of adjusting spacers 4 by inverting them every other time, as shown in FIG. ing.

The cut-out adjustment spacer 4 has a hollow interior so that it can be stacked in a fitted manner as shown in FIG. 6 during storage and transportation.

The base 5 is constructed as shown in FIGS. 7 and 8.

That is, a plate-like body 15 having a composition σ of a size on which the adjusting spacer 4 can be placed is made of shaped steel, and adjustment bolts 16 are provided at each corner of this plate-like body 150.

The adjustment bolt 16 is screwed into a cylindrical body 17 fixed to the plate-like body 15, and moves up and down to adjust the height of the adjustment spacer.

The main part of the circle F is shown in a perspective view within the circle F'.

A lock nut 161 for fixing the screwing height is screwed into the adjustment bolt 16, and the tip of the adjustment bolt 16 is force-machined into a square shape so that it can be rotated with a ratchet spanner.

Furthermore, a protrusion 18 and a recess 19 corresponding to the recess and protrusion of the lowermost adjusting spacer 4 are provided on the upper surface of the base 5.

The bed 3, adjustable spacer 4, and base 5 constructed as described above are assembled in a tunnel etc. as shown in Fig. 1 before use. The number of azimuths and t-spacers 4 to be stacked is appropriately selected so as to make fine adjustments using the adjusting bolt 16 of the bezel 5.

In addition, in order to fix the entire pedestal 1 in the installation position, a fixing wire 22 having a turnbuckle 21 is stretched between a hook 8 provided on the bed 3 and a hook 20 provided in a tunnel etc. to fix the bed 3. Make it fixed.

The cable delivery device 2 placed on the bed 3 is fixed by a lock pin 1 so as not to move when the cable 23 is delivered.

9 and 10 show modified examples of the adjusting spacer.

Rods 24 of equal length are foldably locked at the four corners of one side of the frame 23 made of rectangular Adjust Space fJA section steel with a hinge, and a recess 25 is formed at a fixed position on the stacked surface of each rod and frame. Each of them is provided with a protrusion 26 that can be fitted into the.

A portion of circle G in FIG. 10 is shown in a perspective view within circle G.

The rod is pivotally attached to a bearing 231 welded onto the frame 23 by a shaft pin 232.

The shaft pin 232 is prevented from falling off by a C ring 233.

A plurality of adjusting spacers 4 are used in a stacked manner similar to those shown in FIGS. 4 and 5, and the rod 24 is folded in the direction of the arrow 27 during transportation and storage.

Although not shown, a connecting bar may be interposed between each rod to reinforce the rods 24.

(Effects of the invention) The above-ground cable sending device mount according to the present invention has a structure in which each part can be separated, so it is easy to transport and store, and can be carried into narrow places such as tunnels.

Furthermore, since the structure is simple, assembly and disassembly are easy.

By suitably adjusting the combination of the plurality of adjusted spacers and the adjustment bolt provided on the base, the installation height of the cable delivery device can be freely set.
