Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to cable transportation equipment for laying in a tunnel, which is suitable for laying and transporting power cables and the like.

Conventionally, the effective width of passages that can be used for laying power cables in tunnels is about 600 mm to 1000 mm.
In addition, power cables or trough sockets protruded from both sides, and most of the work had to be done by hand, making it difficult to work efficiently.

There is also a method of installing rails on the ceiling of the tunnel and running pulleys with cables suspended along the rails, but this method has not been widely used because of problems in terms of equipment costs and maintenance.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned difficulties and to provide cable transport equipment for laying cables in a tunnel, which can easily and reliably transport and lay cables in a tunnel.

That is, the cable transportation equipment of the present invention includes a running track for a bogie that is erected on the floor of a passage in a tunnel and has shoulders that continuously protrude on both sides of itself;
It consists of a plurality of carts that can run on this upper surface and have rollers for placing cables on the upper part, and each of the plurality of carts is connected by a connecting rod of a predetermined length, and some or all of the plurality of carts are The truck is characterized in that it is equipped with guide wheels that engage with shoulders of the traveling path.

Hereinafter, one embodiment of the present invention will be described based on the drawings. FIG. 1 is a drawing for explaining the present invention,
A is a cross-sectional view of the tunnel, b is a cross-sectional view of the running path for the trolley, and FIG.
a is a side view showing a roller truck with a simple structure without guide wheels (hereinafter referred to as a "simple truck"); b
FIG. 3 is a side view showing a roller truck provided with guide wheels (hereinafter referred to as a "guided truck"), and FIG. 3 is a plan view showing the trucks connected in a train shape at a bend in the truck running path.

In these figures, the same parts or parts that act in the same way are given the same reference numerals, and 1 is the tunnel;
Reference numeral 2 represents a running path for the trolley, and reference numeral 3 represents a cable mounting shelf provided on the inner wall of the tunnel 1. Reference numeral 4 denotes a truck body, 5 wheels for traveling, 6 guide wheels, 7 a power cable, and 8 a roller rotatably provided on the truck body 4 to support the power cable 7. Reference numeral 9 denotes a simple truck; 10 denotes a guided truck having a structure in which guide wheels 6 are provided on the simple truck 9; and 11 a connecting rod of a predetermined length that connects the simple truck 9 and the guide truck 10.

In addition, the term "predetermined length" mentioned above refers to the guide trolley 1.
This refers to an appropriate length that can be controlled so that the simple trolley 9 connected to the 0, etc. does not deviate from the running path 2 at bends in the tunnel 2, etc., no matter how it travels.

In the cable transportation equipment of this embodiment, as shown in FIG. 1, a running track 2 for a trolley is erected on the floor surface of the central part of the passageway of a tunnel 1, and has shoulders that continuously protrude on both sides of the upper part. A plurality of conical guide carts 10 and simple carts 9 shown in FIG. 2 are arranged on the upper surface of the running path 2. As shown in FIG.

That is, the plurality of carts 9 and 10 are configured such that a simple cart 9 is connected to a guide cart 10 by a connecting rod 11 of a predetermined length, as shown in FIG. When laying the power cable 7, while the power cable 7 is placed on the rollers 8 of the carts 9, 10, the plurality of carts 9, 10 are towed by, for example, traction wires (not shown) and run. Good. When the running path 2 has many curved parts, it is preferable to arrange the simple cart 9 in the middle of the guided cart 10. The power cable 7 is thus easily and reliably conveyed into the tunnel 1.

Note that the power cable 7 is placed on the rollers 8 attached to the top of the trolleys 9 and 10 that run on the upper surface of the running path 2 provided in the center of the floor surface, and is therefore transported. The work of transferring the subsequent cable to the mounting shelf 3 installed on the side of the tunnel 1 is extremely easy.

In addition, it is easy to recover the carts 9 and 10 after laying the cable.

In this embodiment, a plurality of carts are used as a roller cart 1.
0 and simple carts 9, it goes without saying that all the required number of carts 10 with guides may be used.

As explained above, according to the device of the present invention,
It is possible to easily and reliably transport and install power cables, etc. into the tunnel, and has an excellent practical effect of significantly improving work efficiency.

[Brief explanation of the drawing]

FIG. 1 is a drawing for explaining an embodiment of the present invention, in which a is a cross-sectional view of a tunnel, b is a cross-sectional view of a running path for the bogie, and FIG. 2 is a cross-sectional view of the running path for the bogie. 3 is a side view showing a simple cart, b is a side view showing a guided cart, and FIG. It is a top view showing a truck. 1: Tunnel, 2: Trolley running path, 3: Cable mounting shelf, 4: Trolley body, 5: Running wheels, 6: Guide wheels, 7: Power cable, 8: Roller, 9: Simple trolley, 10 : Guided trolley, 11: Connecting rod.
