DETAILED DESCRIPTION OF THE INVENTION

[0010]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hose or a cable for supplying air or electricity to a liftable car deck in an automobile carrier.

In a liftable car deck of a car carrier, a movable deck (hereinafter referred to as "RV car") which rises and descends between fixed decks when a vehicle having a high vehicle height such as an RV vehicle appears as a fixed amount of cargo in transporting the car. In recent years, there has been a liftable car deck which is one stage raised and two stages raised, and the range of ascending and descending is increased, and the length of a hose or a cable is increased.

[0030]

2. Description of the Related Art Conventionally, as shown in FIG. 4, a liftable car deck 31 which rises and descends along a hull 32 or pillars is provided, and the liftable car deck 31 is provided with the liftable car deck 31 as shown in FIG. Air is needed to activate the support device to hold the hull in place
An air line was connected to the liftable car deck 31 by an air hose 34 made of rubber or the like from an air device 33 laid on the 32 side.

The liftable car deck 31 has a general lighting cable 35 required for cargo handling, an explosion-proof lighting cable 36 required for transportation and the like, a fire detector cable 37, and a device for confirming the operation of the supporting device. Limit switch cable
38 is required, and the electric wires 351, 361, 371, and 381 laid between the frames 40 on the hull 32 side are wired to the liftable car deck 31 by cables such as cabtires.

The liftable car deck 31 moves up and down a predetermined height. The air hose 34, general lighting cable 35, explosion-proof lighting cable 36, fire detector cable 37 and limit switch cable 38 are Even if the liftable car deck 31 descends to the lowermost end or rises to the uppermost end, a hose or cable of sufficient length is required,
In each case, the hose or cable itself was hung naked along the wall on the hull 32 side.

[0060]

As described in the prior art, the ends of the hoses or cables of the air hose, general lighting cable, explosion-proof lighting cable, fire detector cable and limit switch cable are respectively twisted. Although measures have been taken to prevent the hose or cable from twisting, the hose or cable itself could not be sufficiently removed, causing twisting or entanglement with the adjacent hose or cable, which hindered lifting and lowering. There was a problem that it hindered the running of the car when loading, for example.

Further, the liftable car deck is designed to move up and down in a place with a small gap. When the liftable car deck moves up and down, the hose or cable is shaken or twisted, and the hose or cable is pinched, damaged or cut. Or, there was no danger of disconnection.

The present invention has been made in view of such insufficient points of the prior art, and has as its object to provide a hose or cable with a hollow bent cable duct. It is intended to protect pipes and cables from mechanical damage such as pinching of hoses or cables, and to arrange hoses or cables through hollow bent cable ducts to prevent twisting. It eliminates entanglement.

A box is provided, and a moving end fitting of the cable duct is fixed to a wall of the storage box, and an air hose and general lighting are respectively provided. Cable, explosion-proof lighting cable,
The fire detector cable and the limit switch cable are pipes or wiring at necessary places in the liftable car deck.

In a liftable car deck that moves up and down along the hull or pillar, an air pipe or electric wiring is piped or wired to the hull or pillar, and an air hose, a general lighting cable, an explosion-proof lighting cable. The fire detector cable and the limit switch cable are incorporated in a cable duct, and a fixed end fitting is provided at one end of the cable duct, and the fixed fitting is fixed to the hull. It is connected to the electric wiring source, and the moving end fitting of the cable duct is fixed to the liftable car deck, and in one direction only in a U-shape due to the weight of the cable duct
It is bent and suspended, fitted between frames, guided by guide plates on both sides of the cable duct, following the lifting and lowering of the liftable car deck, and piping or wiring is performed at necessary places in the liftable car deck It is.
