Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building unit carrying apparatus, and particularly to a narrow unit where a truck cannot enter.
Alternatively, it can be used to transport a box-shaped building unit to a construction site via a sharply curved road.

[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 is appropriately selected according to transportation conditions, and if necessary, transshipment of building units between different types of freight vehicles. ing. By the way, not all construction sites on which unit-type buildings are built can be reached while the building units are loaded on the above-mentioned freight vehicles. For example, there are various roads such as narrow roads that are difficult for small freight vehicles to pass, and roads with sharp curves. Conventionally, when transporting a building unit via such a road, a trolley 70 for transportation as shown in FIG. 7 is prepared at a predetermined place, and a large or small cargo is loaded on the trolley 70. Building units 10 that have been transported by car
Is transferred and fixed, and the carriage 70 is moved to be transported to the construction site. Here, the carriage 70 has wheels 72, 73 on the front, rear, left and right on the back side of the luggage carrier 71. The wheels 72, 73 are connected to each other at the front and rear, and the wheel 72 on the front side in the traveling direction is provided at an intermediate position between them. It is possible to turn via a rotation shaft 74 that is formed.

[0004]

In the transportation of the building unit 10 by the dolly 70 described above, when the front and rear wheels 72 and 73 are positioned in substantially parallel directions as shown in FIG. A range S surrounded by a line connecting the centers of 72 and 73 (represented by an imaginary line in the figure and temporarily referred to as a stable region) S has a substantially rectangular shape.
However, when the dolly 70 turns a curve, the left and right wheels 72 move as the front wheel 72 turns around its pivot shaft 74 as a fulcrum.
72 and 72 are the center lines C in the longitudinal direction of the carriage 70 passing through the rotary shaft 74.
As a result, the shape of the stable region is gradually changed. When the curve reaches the maximum, that is, 90 degrees, the front wheels 72, 72 are located on the center line C, and the stable region S is located on the center line C as shown in FIG. It is an isosceles triangle formed by the front wheel 72A and the centers of the rear wheels 73, 73.

On the other hand, the center of gravity of the building unit 10 often has an eccentric center of gravity due to internal specifications. Therefore, if such a building unit 10 is carried on the above-mentioned trolley 70 and conveyed, the wheels 72, 72 turn around the rotation axis 74 according to the shape of the road, and the shape of the stable region S also changes, As a result, the position of the center of gravity of the building unit 10 may deviate from the stable area S, and the posture of the building unit 10 becomes unstable, and the building unit 10 tends to fall down, which is dangerous. In particular, as shown in FIGS. 7 and 8, the building unit 10 having the center of gravity M on the front side is a trolley.
When placed on 70 and sharply curved during transportation, the center of gravity M is completely out of the stable region S of the isosceles triangle, so the posture of the building unit 10 becomes unstable, and the building unit 10 easily falls, It was difficult to carry on curved roads.

[0006] It is an object of the present invention to provide a building unit carrying device which can carry a building unit in a stable posture even on a sharply curved road and can be carried safely.

[0007]

SUMMARY OF THE INVENTION Therefore, according to the present invention, there is provided a base for supporting a building unit, wheels provided at the front, rear, left and right of a lower part of the base and capable of turning in a horizontal plane at respective mounting positions, and these. And a synchronous turning means that connects the front sides of the wheels and the rear sides of the wheels to each other so that they can synchronously turn.

Here, the synchronous turning means may be provided with a handle, and the mounting position of the handle may be changeable in the left-right direction of the base body.

[0009]

In the present invention as described above, the wheels provided on the lower part of the base body in the front, rear, left and right directions turn in the horizontal plane at the respective mounting positions. Therefore, the positions of the four front and rear wheels are temporarily cut to the maximum curve. It does not change significantly, and the area in which the building unit is placed is surrounded by four wheels and has a substantially rectangular shape. Since the building unit is supported by the base body having such wheels, the posture of the building unit is stable even during transportation on a sharply curved road, and as a result, the building unit can be transported safely, thereby achieving the above object.

It can be positioned in any position.

A procedure for transporting the building unit 10 to the construction site by the transport device 1 will be described. Carrier 1
Is transported to a predetermined place where a lorry cannot enter, for example, by a dedicated carrier with a jig that holds the frame 4, and is lowered to that position. At this time, the carrying device 1 expands the width and length of the frame body 4 so as to suspend the building unit in accordance with the size of the building unit to be carried in, and extends the legs 3. When the building unit 10 is carried in, for example, by a large-sized freight car and further unloaded to a predetermined place by a crane or the like, the worker moves the carrying device 1 and puts the building unit 10 inside the carrying device 1.

Next, the building unit 10 is engaged with the hook 7 of the carrying device 1 using the hanging bolts or the like attached thereto, and the legs 3 are extended to suspend the building unit 10. After that, the other end of the node-short link 60 and both ends of the node-length link 61 are connected by a link pin 65, and the turning synchronization means 6 is attached to the frame body 4 side.

One operator pulls the front handle 64, and the other operator pushes the rear handle 64 while appropriately changing the position of the handle 64 according to the shape of the road. The building unit 10 is moved to the left side L or the intermediate position C and transported to the construction site. At the construction site, the building unit 10 is unloaded from the frame body 4 by the operation opposite to the above-described hanging work, the turning synchronization means 6 of either the front or rear is removed from the leg 3 side, and the handle 64 of the other turning synchronization means 6 is removed. To pull the frame body 4 out of the building unit 10.

Further, when transporting the next building unit 10, the removed swing synchronizing means 6 is attached to the frame body 4 again, and the handle 64 is pulled as it is to return to a narrow road or the like, and the building unit 10 is suspended again and transported. To do. When the transportation of the building unit 10 is completed, the transportation device 1 reduced in the width direction, the longitudinal direction and the height direction is loaded into a dedicated freight vehicle by a crane or the like and transported to a factory or the like.

According to this embodiment as described above, the following effects can be obtained. That is, the building unit 10 is hung on the upper frame 2 of the frame body 4, and the lower end of the unit 10 penetrates through the open portion at the lower part of the frame body 4 and is lowered to near the ground. It is lower than that of the carrier device, and the entire unit 10 is stable. Therefore, the risk of the unit 10 falling over during transportation is reduced.

Further, since the wheels 5 provided at four front and rear positions on the lower surface of the frame body 4 can independently turn at each position with the turning shaft 51 as the turning center, even if a large curve is cut,
Although the position of the tire 53 slightly moves around the rotation shaft 51, the shape of the stable region formed by being surrounded by the front, rear, left, and right tires 53 is still substantially rectangular as shown in FIG. And does not change. Therefore, even a building unit with an eccentric center of gravity is located in the stable area, so the posture is stable and it can be safely transported even on a sharply curved road.

Furthermore, since the building unit 10 is suspended within the frame 4, the unit 10 with the outer wall attached
The surface does not project outside the frame 4, and therefore, even during transportation on narrow roads, etc., it will not come into contact with trees along the road, telephone poles built along the road, fences, etc. It is possible to prevent the unit 10 from being damaged.

Furthermore, since the handle 64 can be easily moved to the three positions of the node-length link 61, the right side R, the intermediate position C, and the left side L, depending on the narrow road, for example, when the vehicle is turning to the right, the handle 64 is used. It can be pulled after being set to the right R position. Therefore, since the right side of the road can be seen well, the frame body 4 can be safely transported without colliding with the trees along the road, a telephone pole, or the like. In addition, since the handle 64 is attached to the front and rear of the frame body 4 in the traveling direction and can be moved to three positions in each of the front and rear positions, the operability is improved.

To suspend the building unit 10,
After setting the leg 3 to a height corresponding to the unit 10, hook the hook 7 on a hanging bolt or the like attached to the unit 10,
Only by extending the legs 3, the work is easy and can be performed in a short time.

The present invention is not limited to the above-mentioned embodiment, but includes the following modifications. That is, in the above-described embodiment, the turning synchronization means 6 is the link mechanism 62 in which the handle 64 can be positioned at three positions of R, C, and L of the node-length link 61, but not limited to this, for example,
The turning synchronization means 10 as shown in FIG. 6 may be used. Here, the same parts as those in the above embodiment are designated by the same reference numerals, and the description thereof will be omitted or simplified. Turning synchronization means 10
Is provided with a link mechanism 62, and the node length link 61 of the link mechanism 62 is connected to the middle of the handle 11. One end of the handle 11 is rotatably connected to a handle fulcrum 13 of a fixed rod 12. The fixing rod 12 is detachably attached to the bracket 14 attached to the reinforcing leg 32. In such a turning synchronization means 10, since the handle 11 can turn with respect to the handle fulcrum 13,
Driving operation can be performed by changing the handle 11 in any direction according to the shape of the road.

In the above embodiment, the handle 64 can be positioned at three positions R, C and L of the node-length link 61, but the handle 64 is not limited to three positions and may be increased to, for example, five positions. .

Further, in the above embodiment, the operator pulls and pushes the handle 64 to move the carrying device 1, but the present invention is not limited to this. For example, a frame is provided at the front part of the leg 3 or the like. A self-propelled motor may be provided by installing a motor and a handle or the like.

The front and rear four wheels 5 are mounted on both ends of the mounting shaft 52 connected to the rotary shaft 51. However, it is sufficient if each wheel 5 can turn at its respective mounting position. Alternatively, the tip of the rotatable shaft attached to the lower surface of the reinforcing leg 32 may be bent into a substantially V shape while leaving a predetermined vertical portion, and one wheel may be attached to the bent lower portion. Even in this case, the above-mentioned effects can be obtained.

In addition, the specific structure and shape for carrying out the present invention may be any other structure as long as the object of the present invention can be achieved.
