Abstract

PURPOSE:To easily transport a heavy material without using an auxiliary facility such as, for example, crane, by splitting a heavy weight carrier vehicle into three sections, a tractor, a carrier bed and a trailer, and as well by firmly coupling these three sections with the use of a plug-in structure. CONSTITUTION:A coupling member 3 is attached to a dolly 2 attached to a tractor body 1. The coupling member 3 may be elevated at the connecting part of the dolly by means of a hydraulic device 4, and has a plug-in part 6. A carrier bed 7 carrying thereon a heavy weight material to be transported, is formed therein with a fitting hole adapted to be engaged with the plug-in part 6. A trailer composing vehicle 11 is self-propelledable, and is attached thereon with a coupling member 12 having a plug-in part 15 adapted to be engaged with a fitting hole formed in the carrier bed 7. When the coupling member 3, the carrier bed 7 and the trailer composing vehicle 11 are coupled together, these three constitutes an integral trailer car. In this condition, the hydraulic units 4, 13 are simultaneously operated to make it possible to run the entire trailer vehicle.

Description

[Detailed description of the invention] The present invention relates to a vehicle suitable for transporting heavy objects.

BACKGROUND ART Many large and heavy devices must be installed in facilities such as various plants, nuclear power plants, thermal power plants, etc., and special vehicles and cargo handling equipment are required to transport these devices overland.

In particular, large cranes are required when loading and unloading heavy objects, but the locations where equipment is loaded and unloaded are not limited to locations with such facilities, for example, oil fields under construction in the desert or other locations. 1) There are many places where cargo handling equipment is inadequate, such as petrochemical plants.

For this reason, several types of structures for heavy goods transport vehicles that do not require a crane have been proposed, but all of them have problems such as strength problems and complicated structures.

This invention was constructed in view of the above-mentioned problems,
An object of the present invention is to provide a vehicle that can easily transport heavy objects.

In short, this invention divides the structure of a vehicle into three parts: a towing vehicle for towing heavy objects, a platform for placing heavy objects, and a trailer, and the structure is structured so that the king of brackets is inserted and connected more firmly to the structure. It is a goods transport vehicle.

Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show a first embodiment of the invention.

In the figure, reference numeral 1 is a towing vehicle main body, 2 is a dolly attached to this main body, and 3 is a connecting body attached to this dolly 2. The connecting body 3 is constructed so that it can be raised and lowered by a hydraulic device 4 at the dow joint. 5 is a hydraulic unit for lifting and lowering the connecting body attached to the dolly. An insertion portion 6 is formed on the connection body 3 (J) to be inserted into and connected to an insertion opening of a mounting table (to be described later).

Reference numeral 7 is a mounting table on which a heavy object to be transported is placed, and reference numeral 8 is an insertion opening that engages with the insertion portion 6 of the connecting body 3. By the way, the heavy object 9 shown in Figure 2 is a container called a cask that stores the spent fuel of a nuclear reactor, and this cask is usually cylindrical with a length of about 5.9 m and an outer diameter of about 2.3 m. ,
It weighs about 75 tons, and when you add the weight of the 100 frames to which it is fixed, it becomes quite heavy.

11 is a trailer configuration vehicle and is capable of self-propulsion. 12
is the connection body attached to this trailer configuration vehicle, and the towing vehicle l
It has the same structure as the connecting body attached to , and is raised and lowered by a hydraulic system, and has an insertion part 15 that engages with the insertion opening 14 of the mounting table 7 . 16 is a hydraulic unit;
Reference numeral 17 denotes a driver's cab, which is equipped with an engine and a steering mechanism so that the driver can travel freely and independently.

FIG. 4 shows an example of a method of engaging the connecting body 3 and the mounting table.

The tip of the insertion part 6 of the connection body 3 is a tapered part 6a, which is formed so that it can be easily inserted into the insertion opening 8 of the mounting table 7 on which a heavy object is placed in advance. A connector 18 is attached to the tip of the tapered portion 6a, and is configured to be connected to a connector 19 attached to the mounting table side when insertion into the insertion port 8 is completed.

A laser oscillator 20 is a positioning device attached to the connector 18, and irradiates a laser beam 22 to a laser receiver 21 provided on the connector 19 on the mounting table 7 side. The connecting body 3 is moved and aligned so that the laser beam 22 can be received by the light receiving part 21, and then the connecting body 3 is moved back and the insertion part 6 is inserted into the insertion opening 8 to a predetermined depth. At this time, it is preferable to turn on the lamp 40 etc. once the alignment is completed (see FIG. 3). At this point, connectors 1B and 19 are also connected. In this state, bottles are inserted into the bottle holes 23 and 24 formed in both the insertion part 6 and the mounting table 7, and both are fixed. Note that the reference numeral 25 in the figure is a cushioning material made of a flexible material such as rubber.

On the other hand, the connecting body of the trailer component vehicle 11 has a similar structure, and a connector with a positioning device is attached to the tip of the connecting body 15, and by connecting the connecting body and the mounting base, the mounting base 7 side A signal circuit is constructed between the control device attached to the towing vehicle side and the trailer component vehicle 11 via wiring within the mounting table 7. In addition, to connect the trailer component vehicle 11 and the mounting platform 7, an operator rides on the driver's cab 17 of the trailer component vehicle 11 and moves the trailer component vehicle to the platform 7, and then connects the two. Furthermore, once the connection of the vehicle with the trailer is complete, the transmission is set to neutral and the steering mechanism is fixed.

Connection body 3. Mounting table7. By connecting the trailer component vehicles 11, an integrated trailer of "Championship 1" is constructed. In this state, a command signal is issued by the control device attached to the driver's cab of the towing vehicle 1, and the hydraulic devices 4 and 13, which are lifting devices,
are activated simultaneously to raise and fix the mounting table 7 to a predetermined height while keeping it horizontal, thereby creating a certain space between the mounting table 7 and the road surface. In this state, the entire heavy goods transport vehicle becomes movable and starts traveling towards the destination.

At the destination, the tow vehicle 1.
Mounting table7. Cut the trailer component vehicle 11), install it in a predetermined position, or let it be carried in. In addition to long-distance land transportation, this vehicle can also be used for cargo handling work such as loading and unloading heavy objects into and out of ships such as RO-RO ships (roll-on, roll-off ships) where vehicles can drive inside the ship. It can be used very effectively.

In addition, when moving backwards of the transport vehicle or when fine-tuning the position of installing heavy objects, the steering mechanism of the trailer component vehicle 11 is unlocked and the trailer component vehicle 1 is moved in correspondence with the towing vehicle.
1 may also be steered. In this case as well, it is of course possible to configure the vehicle so that it can be controlled centrally by the control device of the towing vehicle 1.

Figures 5 and 6 show another embodiment.

In this embodiment, the auxiliary wheels 26 are attached to the mounting table 7 in a semi-embedded manner. When the connecting bodies 3 and 12 are raised and the mounting base is set at the position when the vehicle is running, as shown in Fig. 5, a certain space is formed between the auxiliary wheels and the road surface, and the auxiliary wheels do not touch the ground. Configure it like this. When formed in this way, there are almost no restrictions on where heavy objects can be loaded or unloaded, and it is possible to move short distances without the need for a trailer.

FIG. 6 shows an example of how the transport vehicle is used in this embodiment.

For example, when a heavy object is transported and arrived at the site, the place where the heavy object is placed is higher than the road surface, as shown by reference numeral 27, or there is a wall surface 28, and the heavy object is placed close to this wall surface. In this case, the trailer component vehicle 11 becomes an obstacle. In this case, the transport vehicle is temporarily stopped at a predetermined location, and the connecting body 3 on the towing vehicle and the connecting body 12 of the trailer component vehicle 11 are lowered to ground the auxiliary wheels 26 of the platform 7. to support the load. In this state, the trailer component vehicle 11 is separated, and the towing vehicle 1 drives the mounting platform 7 and stops at a predetermined location. In addition, when moving the towing vehicle 1 backward, including in this case, the dolly 2 will be in a state where force is applied from the front and back due to the load of the heavy object and the backward force of the towing vehicle, and the dolly 2 and the mounting base 7 will move. A phenomenon in which the blade is twisted and positioned diagonally with respect to the direction (junk knife phenomenon) is likely to occur.

For this reason, a steering mechanism was also installed on the doe 92,
It is preferable to steer the dolly 2 so that it is always positioned in the moving direction. This steering may also be configured to be centrally controlled from the towing vehicle, or may be configured such that only this dow can be independently steered.

By implementing this invention, heavy objects can be easily transported without requiring auxiliary equipment such as a crane.

The towing vehicle, mounting platform, and trailer component vehicles are plug-in type, making them easy to attach and detach, and when connected together, they have great strength and can withstand the load of a heavy object for 1 minute.
