Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit carrier,
In particular, it can be used to transport various units such as building units that make up a unit-type building to a construction site via narrow roads, roads with sharp curves, roads with slopes in the width direction, and roads with many slopes. .

[0002]

BACKGROUND ART In recent years, as prefabricated houses and other buildings,
A unit-type building in which a plurality of box-shaped building units and roof units are combined is used. Such a unit-type building is constructed by manufacturing the building units and the like in advance in a factory, transporting the building units and the like to a construction site by a lorry or the like, and building the building units and the like in combination there.

A large-sized or small-sized freight vehicle used for transporting such building units or the like is appropriately selected according to transportation conditions, and if necessary, transshipment of building units between different types of freight vehicles. It is being appreciated. by the way,
Not all construction sites on which unit-type buildings are built can be reached while the building units are loaded with the above-mentioned trucks and the like. For example, there are various roads such as narrow roads that are difficult for small freight vehicles to pass through, roads with sharp curves, roads with slopes in the width direction, and roads with many slopes. Conventionally, when transporting a building unit or the like via such a road, when a small freight vehicle cannot be used, a truck for transportation is prepared at a predetermined place, and a large or small truck is mounted on this truck. The building units etc. that have been transported by the freight vehicle are transferred and fixed, and the carts are moved to the construction site. Here, the bogie has wheels on the front and rear, and on the left and right, and these wheels are connected to each other on the front and rear, so that the wheels on the front side in the traveling direction can turn through a turning shaft provided at an intermediate position between them. ing.

[0004]

However, in transporting a building unit by a dolly as described above, for example, when moving on a road having an inclination in the width direction, the whole body is inclined along the inclination of the road, so that the center of gravity is lowered. There was a risk that the position of the would shift and fall, which is dangerous. For this reason, many workers support the building unit so that it will not fall, or carry jigs that prevent the building unit from falling over, but there is still a risk that it will fall over. The problem has not been solved, and there was a desire for a transport vehicle that can be safely transported on any road.

Further, when the bogie turns a curve, as a result of the wheels on the front side turning around the pivot as a fulcrum, the position of the wheels changes according to the degree of the curve, and a range surrounded by the front and rear wheels (called a stable region) ) Shape also changes. When the curve is maximized, the front wheels are arranged parallel to the rear wheels on an orthogonal line, and at this time, the stable region is formed by the front rotation shaft and the rear wheels. It becomes an isosceles triangle and becomes unstable. On the other hand, the center of gravity of a building unit often has an eccentric center of gravity due to internal specifications. Therefore, if such a building unit is placed on the above-mentioned trolley and transported, the position of the center of gravity may deviate from the stable area, the posture of the building unit becomes unstable, and the building unit easily falls and is dangerous. There was also. In particular, when a building unit with its center of gravity on the front side is greatly curved when it is transported, the center of gravity will be completely out of the stable area of the above-mentioned isosceles triangle. Was difficult.

In the case of transporting a building unit by a trolley, usually, a plurality of workers pulls or pushes the transport, but for example, when transporting on a slope, it is pushed back when climbing and momentum when descending. Since it is accompanied by danger, and in that case, another traction means is required, and many facilities are required.

An object of the present invention is to provide a unit transport vehicle which can maintain a stable posture on any road shape and can be transported safely and easily.

[0008]

SUMMARY OF THE INVENTION Therefore, the present invention is a unit transporting vehicle for transporting various units including a building unit constituting a unit type building, the vehicle having wheels, a loading platform for loading the unit, A unit transport vehicle is configured by including a posture adjusting means for supporting the posture of the platform so as to be tiltable on the vehicle body.

Here, the wheels of the unit carrier may be endless tracks.

[0010]

According to the present invention as described above, the carrier of the transporting vehicle on which the unit is loaded is supported by the vehicle body such that the attitude can be appropriately tilted by the attitude adjusting means. Since the loading platform is appropriately tilted according to the shape of the road, the loading platform maintains a horizontal state and the unit maintains a stable posture. Therefore, it can be safely transported on roads of any shape, thereby achieving the above-mentioned object.

Further, if the wheels of the transport vehicle are in the endless track, the ground contacting ability is high, so that the vehicle can easily travel even on a steeply climbing and descending slope, and can easily make a sharp turn.
