JPH06204725A - Device for correcting absolute position of antenna installed on ground against crustal movement - Google Patents

Abstract

PURPOSE:To obtain a correction device for the absolute position of an antenna installed on ground against crustal movements by correcting the level with earth removal or banking and moving a base of the antenna in X, Y directions to correct a horizontal change thereby eliminating a hindrance on reception. CONSTITUTION:X, Y, Z displacement amounts of an antenna A are measured to obtain a position correction amount of an antenna base B to restore the position of the antenna A to an installed position. Then a transfer machine D is set, the base B is hoisted with wires 17 by a winding trolley 16 to move the base in the left direction in figure. As a result, a ground G is digged by a digging screw 21, a screeder is used to level required for earth removal or banking to form the ground in which the displacement in the direction Z is corrected, and a travelling frame 12 is moved in the right direction in the figure synchronously with the movement of the transfer equipment D. In the case of the movement, an earth removal conveyor 23 is used to carry removed earth or to supply earth for banking. When the base B is moved to the home position, the transfer equipment D and the travelling frame 12 are stopped to move the position of a traverse frame 15 and the travelling frame 12 thereby correcting the displacement in the X, Y directions, the base B is descended to the ground G and then the antenna A is set.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an absolute position correction device for ground fluctuation of an antenna installed on the ground.

[0002]

2. Description of the Related Art Antennas installed on the ground, such as fixed-point observation antennas, parabolic antennas, and radar antennas, are required to have their absolute positions unchanged.

[0003]

However, in a volcanic island, for example, the absolute position of the installed location changes due to crustal deformation. It is known that the absolute position can be easily obtained using artificial hygiene, but a technique for correcting the absolute position to the obtained absolute position has not been established.

An object of the present invention is to provide an absolute position correction device for ground fluctuation of an antenna installed on the ground.

A correction device according to the present invention comprises a frame body having a traveling means, an antenna suspension device provided on an upper portion of the frame body along a traveling direction, and a lower portion of the frame body. The antenna suspension device comprises an antenna traveling girder, an antenna traveling frame having traveling means suspended from the traveling girder, and an antenna traversing device suspended from the traveling frame. It comprises a traverse frame provided with a device and a plurality of antenna hoisting trolleys provided on the traverse frame, and the floor-equipped device comprises an excavation / excavation mechanism and a screed mechanism.

It is preferable that the suspension wire wound around the antenna winding trolley be detachably connectable to a suspension bolt that is erected on the antenna foundation on which the antenna is erected.

[0007]

In the correction device constructed as described above,
The X, Y, and Z displacement amounts of the antenna are measured by a known method, and the position correction amount of the antenna foundation for returning the antenna to the set position is obtained. Therefore, the correction device is set and the antenna foundation is lifted. Next, the correction device is moved so that the ground leveling or embankment leveling of the ground is performed by the flooring device, and the antenna direction is moved in the opposite direction in synchronization with the movement. Finally, when the antenna foundation moves to the almost original position, adjust the positions of the traveling frame and the traverse frame to X,
After correcting the displacement in the Y direction, set the antenna foundation to the corrected setting position on the ground.

Referring also to FIG. 2, the excavating screw 21 of the floor-equipped device 20 is provided on the steering cylinder 3 side of the frame 1, and in the Y direction of the screw 21, a screeder 22 and an earth discharging conveyor 23 are provided. Has been.

Next, a modification mode will be described.

First, the X, Y, Z displacement amounts of the antenna A are measured by a known method, and the position correction amount of the antenna foundation B for returning the antenna A to the set position is obtained.

Then, as shown in FIG. 2, the reshuffling machine D is set, the hoisting trolley 16 is operated, and the antenna foundation B is hoisted by the hoisting wire 17.

Next, as shown in FIG. 3 and FIG. 4, the reshuffling machine D is moved in the direction of arrow a, the ground G is excavated by the excavating screw 21, and the screed 22 leveles the floor, or
Ground G with embankment leveling and displacement in Z direction corrected
