[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leveling device applied when leveling equipment in a plant construction or the like, and more particularly to an equipment for installing many equipment at the same level such as an electric equipment panel. This is applied to leveling of the base material.

[0002]

2. Description of the Related Art A conventional leveling operation of a base material for installing an electric equipment panel will be described with reference to FIG. First, an inking line 1 indicating the installation position of the electrical equipment panel is drawn on the floor. Then, the installation base member 2 is provisionally positioned and arranged so as to substantially coincide with the installation position. At this time, the jacks 3 are arranged at the four corners of the installation base material 2 respectively. Therefore, the jack 3 is operated to raise and lower the installation base material 2, and the installation base material 2 is adjusted to a predetermined height while checking the transmission base (not shown) from another place (height position adjustment). ). Next, the hanging down 4 is hung from the installation base material 2, and it is confirmed whether or not the position of the hanging down 4 matches the ink mark line 1.

If the position of the lowering swing 4 does not coincide with the inking line 1, the installation base member 2 is hit with a wooden hammer (not shown) to move the installation base member 2 in the horizontal direction. Then, the front, rear, left and right positions of the base material 2 for installation are finely adjusted, and the position of the downspout 4 is adjusted to the ink line 1 (horizontal position adjustment). At this time, since the installation base member 2 is forcibly moved on the head of the jack 3, the stability of the jack 3 is lost and fine adjustment is difficult. Furthermore, when the adjustment amount is large, the jack 3 falls over when the installation base 2 is largely moved by hitting with a wooden hammer. In this case, the installation base 2 is once manually lifted to roughly adjust the position, and then finely adjusted by hitting with a wooden hammer. Alternatively, a spacer (not shown) is inserted between the installation base material 2 and the floor, the jack 3 is lowered to support the installation base material 2 on the spacer, and the installation base material 2 is wood hammered. While moving the installation base material 2 in the horizontal direction, the front, rear, left and right positions of the installation base material 2 are adjusted so that the position of the down swing 4 matches the marking line 1.

[0004] When the position of the lowering swing 4 matches the ink marking line 1, the jack 3 is operated to raise the installation base material 2 to adjust the height to a predetermined height. This operation is repeated to adjust the position of the installation base material 2 in the up, down, left, and right directions, that is, when leveling is completed, the installation base material 2 is fixed to the floor surface by welding using base legs (not shown). afterwards,
The jack 3 is removed, and the installation of the installation base material 2 is completed.

[0005]

As described above, the leveling of the conventional installation base material 2 is performed by adjusting the height position by the jack 3 and hitting the wooden hammer while being supported by the jack 3 or the spacer. Since the horizontal position adjustment and the horizontal position adjustment are performed alternately, there is a problem that the operation is complicated and the operation time is lengthened.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and enables the apparatus itself to move up and down and back and forth and left and right to improve leveling workability and reduce work time. The aim is to obtain a leveling device that works.
