Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a propeller carrier used when transporting a propeller overland by a truck, trailer, or the like.

As conventional propeller carriers, those shown in FIGS. 1 to 3 have already been proposed.

The propeller carrier shown in Figures 1 to 3 is constructed by attaching carrier b to the loading platform of a special truck a in a pendulum manner via support pins e, and when loading the propeller, carrying carrier b is attached as shown in Figure 2. The propeller e is held horizontally and fixed with a fixing nut f, and then, as shown in FIG. 3, the carrier b is rotated about 400 degrees along with the propeller e and fixed with a fixing pin d.

As mentioned above, this transport platform b has a complicated structure due to the pendulum and is heavy, resulting in problems such as a reduction in the net transport capacity of the truck and the need for a dedicated truck due to its structure. In the present invention, one end of a pedestal having a substantially L-shaped cross section that is removably attached to the loading platform of a truck or the like is pivoted near the top of one vertical side of the pedestal, and the other end is pin-coupled to one horizontal end of the pedestal when transporting the propeller. a propeller fixing base attached to the propeller fixing base, a propeller fixing member attached to the fixing base, and a removably interposed plate between the free end of the propeller fixing base and the horizontal piece of the base when fixing the propeller to the propeller fixing base; It is characterized by consisting of a fixing base (see above) and a support bracket that holds the propeller horizontally and is removed after fixing the propeller.The purpose of this is to create a propeller carrier that has an extremely compact structure and eliminates the problems of conventional propellers. is to provide.

The present invention is composed of the above-mentioned pedestal, propeller fixing base, propeller fixing member, and support metal fittings, and these propeller fixing base, propeller fixing member, and support metal fittings are all pivotably or removably attached to the pedestal. . Therefore, the present invention allows the propeller to be mounted and transported by simply attaching the base incorporating the propeller fixing base, propeller fixing member, and supporting metal fittings to the loading platform of a truck or the like in a removable manner. There is no need to use a special transport platform.

Therefore, the weight of the transport platform can be significantly reduced, the net transport capacity can be improved, and ordinary trucks and trailers can also be used.

An illustrated embodiment in which the present invention is applied to a truck will be described below.

In this embodiment, as shown in FIG. 4, a propeller fixing base 2, which is pivotally attached to the vertical top of a pedestal 1 having an approximately L-shaped cross section and fixed on the bed of a truck 9, is supported by two supporting hardware 5. e) Hold it horizontally and use a crane or the like (not shown) to lift the propeller 10 on top of the boss fixed mandrel 4 which is shielded from the fixed base 2, and together with the boss fixed mandrel 4 constitute a propeller fixing member. Fix with nut 4'.

Next, a lifting hole 7 provided at the free end of the fixed base 2
Pass the wire (not shown) through the support pin 3 with the crane.
After lifting it up using it as a fulcrum and removing the free support hardware 5, the fixed base 2 is gently suspended together with the propeller and lowered onto the support hardware 6 provided on the horizontal piece of the base 1, and then attached to the anti-sway pin 8. to fix the fixed base 2 to the base 1.

By the above operation, the propeller 10 is tilted at the set angle, and the package (middle) B is reduced to B' as shown in FIG.

When lowering the propeller 10, the procedure above can be reversed.

Although two supporting metal fittings 5 are used as described above, it is not necessary to use two, and the supporting metal fittings 6 are used to fix the free end of the propeller fixing base 2 to the pedestal 1 when the propeller fixing base 2 is tilted.
Although this is done with a groove fixing pin 8, various fixing means other than these configurations can be used as the weave fixing means.

Since this embodiment is constructed as described above, it is possible to significantly reduce the weight compared to a pendulum-type carrier with support at both ends of the follower, and to increase the net transportation capacity of the truck.

In addition, in this embodiment, the above-mentioned pedestal 1 is detachably attached to each droplet of a truck, etc., so there is no need to use a dedicated truck as in the past, and a general truck or trailer can be used, making it suitable for general use. It can have excellent practical effects, such as being convenient because it can be made to have a unique character.
