[0017]
Here, a description will be given of a transporting method of the thus configured heavy load transporting apparatus of the present embodiment.
[0018]
As shown in FIGS. 1 and 3, in a state where the building 10 to be transported is separated from the foundation and is prevented from falling down, the building 10 is lifted by a jack-up device (not shown), and the heavy object of the present embodiment is placed between the building 10 and the foundation. Insert the transport device. Then, the building 10 is lowered by the jack-up device and placed on the carrier 11 to take measures to prevent the building from falling in consideration of safety. In this state, in the present embodiment, as shown in FIG. 2, the plurality of moving mechanisms 12 are sequentially operated in synchronization with one row of block units A, B, C,.
[0019]
First, in block A, from the state of the moving mechanism 12 at the reference position shown in FIG. 1, as shown in FIG. 5, the drive jacks 21, 22, and 23 are contracted to raise the installation plate 26 from the ground S ( (Up position). At this time, the load of the building 10 on the carriage 11 is supported by the moving mechanism 12 other than the A block, and the number of mounted moving mechanisms 12 and the support of the driving jacks 21, 22, 23 are supported so that the load can be supported. It is necessary to set force and the like in advance.
[0020]
Subsequently, as shown in FIG. 6, by expanding and contracting each of the drive jacks 21, 22 and 23, the installation plate 26 is moved in the moving direction while being raised from the ground S, that is, moved rightward in FIG. Tilt position). Specifically, while the drive jack 21 is contracted and the drive jacks 22 and 23 are extended, each of the drive jacks 21, 22 and 23 swings with the spherical bearing 24 as a fulcrum, and the installation plate 26 is placed in a horizontal state. Move it as it is.
[0021]
Then, as shown in FIG. 7, by extending each of the drive jacks 21, 22, and 23, the installation plate 26 is lowered and installed on the ground S (inclined position). Then, the installation plate 26 can be moved by the distance T.
[0022]
As described above, when each moving mechanism 12 of the A block is operated to move each setting plate 26 by the distance T, next, each moving mechanism 12 of the B block is operated to move each setting plate 26 by the distance T. Further, when each moving mechanism 12 of the B block is operated to move each installation plate 26 by the distance T, similarly, each moving mechanism 12 of the C to O blocks is operated, and each installation plate 26 is moved by the distance T. .
[0023]
When the moving mechanism 12 of each of the A to O blocks is operated to move each of the installation plates 26 by the distance T, all the driving jacks 21, 22, and 23 expand and contract to move the carriage 11 in the moving direction, that is, In FIG. 7, it is moved rightward by a distance T. Specifically, by extending the drive jack 21 and contracting the drive jacks 22 and 23, the drive jacks 21, 22, and 23 swing about the spherical bearing 25 as a fulcrum.

[0025]
When the ground S on which the installation plate 26 of the moving mechanism 12 is installed is inclined, when the driving jacks 21, 22, 23 are extended to install the installation plate 26 on the ground S, the inclination of the ground S is reduced. The installation plate 26 is installed in parallel with the ground S by adjusting the amount of extension of each of the drive jacks 21, 22, and 23 according to. Specifically, for example, a pressure sensor is provided on each of the drive jacks 21, 22, and 23 of the moving mechanism 12, and when the respective drive jacks 21, 22, and 23 are extended, the installation plate 26 comes into contact with the ground S and a predetermined pressure is applied. Then, by stopping the extension driving of each of the drive jacks 21, 22, 23, the installation plate 26 can be brought into close contact with the inclined ground S.
[0026]
As described above, in the heavy object transporting apparatus of the present embodiment, a plurality of moving mechanisms 12 are provided at substantially equal intervals below the carrier 11, and each of the moving mechanisms 12 is mounted on the lower surface of the carrier 11 by a spherical bearing. 24, the upper ends of the three drive jacks 21, 22, 23 are connected, and the lower end of each drive jack 21, 22, 23 is connected to an installation plate 26 via a spherical bearing 25. .
[0027]
Accordingly, by moving the installation plate 26 up and down by moving the driving jacks 21, 22 and 23 of the moving mechanism 12 up and down and moving the carrier 11 horizontally, heavy objects can be carried, and Even if there is unevenness or inclination, the loaded heavy object can be stably transported without affecting the carrier such as vibration. In addition, since the carriage 11 is moved by the plurality of moving mechanisms 12 including drive jacks 21, 22, and 23 mounted on the lower part of the carriage 11, a traveling drive unit such as an engine is not required, so that the apparatus can be reduced in size and cost. Cost can be reduced.
[0028]
In the above-described embodiment, the moving mechanism 12 is configured by the three drive jacks 21, 22, and 23. However, it is sufficient that the number of drive jacks is two or more, and the upper ends of the two drive jacks are turned to the carrier. By connecting the lower end to the installation plate rotatably while movably connecting, the carrier can be moved at least in the front-back direction or the left-right direction. Further, the moving mechanism may be constituted by four or more drive jacks 21, 22, 23. Further, the lower portions of the drive jacks 21, 22, and 23 are spread outward and tilted, and adjacent persons are arranged in a truss shape. However, the upper portions of the drive jacks 21, 22, and 23 are spread outward and tilted. Alternatively, adjacent persons may be arranged in a truss shape.
[0029]
As a method of moving the carriage 11 (building 10), a plurality of moving mechanisms 12 are sequentially operated in synchronization with one row of block units A, B, C... O, and each block unit A, B, C When the moving mechanism 12 is operated at O, the driving jacks 21, 22, and 23 are contracted from the reference position to set the installation plate 26 to the raised position, and the driving jacks 21, 22, and 23 are expanded and contracted to the raised inclined position. The carriage 11 (building 10) is extended by extending the drive jacks 21, 22, 23 to the inclined position, and expanding and contracting the drive jacks 21, 22, 23 to horizontally move the carriage 11 back to the reference position. Although the movement is performed by the distance T, the movement procedure of the block units A, B, C... O, the movement mechanism 12 and the installation plate 26 is not limited to this method.
[0030]
For example, a block may be configured by randomly selecting from a plurality of moving mechanisms 12, or the moving mechanisms 12 may be sequentially operated one by one. Further, first, after the drive jacks 21, 22, and 23 are expanded and contracted to horizontally move the carriage 11 by the distance T, the drive jacks 21, 22, and 23 are contracted to raise the installation plate 26, and the drive jacks 21 and 22 are moved. , 23 may be extended and retracted, and the drive jacks 21, 22, 23 may be extended to install the installation plate 26 on the ground S and return to the reference position.
