Generally, in the case of installing or arranging a structure such as a dresser or a household appliance or a household appliance having relatively large volume such as a washing machine or a refrigerator, the bottom surface for installing the structure is not flat, It is a well-known fact that when installing a structure under unfavorable conditions, the installation work of the structure is troublesome and complicated, and there is a lot of trouble in the installation work such as requiring a lot of manpower and labor, as well as the equipment required. Due to these factors, joints such as furniture and the like are generated when the joints are displaced from each other, and expensive furniture is damaged or the door does not fit, resulting in inconvenience in use.

In the case of a structure such as a home appliance using a rotating machine such as a washing machine and a refrigerator, if the rotating machine is operated in a state where the structure is not horizontally rotated, an eccentric rotation operation of the rotating machine, In addition, the rotation shaft of the structure such as the washing machine or the refrigerator or the motor is easily worn or damaged, resulting in damage to expensive electric appliances and the like, and their life span And shorten the service life thereof.

Therefore, in order to level the structures used in homes, it is necessary to place a separate support plate at the bottom of the structure to maintain the level of the structure. However, And there were many inconveniences such as a lot of efforts and inconvenience to maintain and maintain the level of the operation.

In addition, since the structures such as furniture and household appliances have to be repeated many times in order to maintain the level of the structure, the work itself is very difficult and the inconvenience that the elderly or the woman can not easily perform the horizontal adjustment work In general, a bolt-regulating hydraulic cylinder is added to the lower part of each side of a washing machine or a refrigerator to adjust the level in each of the four sides. However, since the bolts of the cylinders, , It is difficult and difficult to precisely adjust the horizontal level by adjusting the horizontal level. Therefore, the horizontal level adjustment operation is very inconvenient because the worker is working in an inconvenient posture where the user is bent. Problems were followed.

Furthermore, in the case of machinery such as a machine tool or a construction structure that emphasizes the horizontal maintenance of the installation state, since the load of the structure is very heavy, the structure is elevated by using a lift device such as a separate jack, a chain block or a hoist And the height adjustment means of the bolts installed at the lower support angles of the structure are adjusted to maintain the horizontal position. In such a case, a separate lift device such as a jack, a chain block or a hoist must be used, There have been various defects such as non-economic defects requiring high manpower and work hours as well as expenses due to the adjustment work, and high skill required for the adjustment work.

When installing the structure, use a separate tool to adjust the height of the bolt or to adjust the height of the bolt manually so that the caster is raised from the ground. When moving the bolt, raise the bolt higher than the bottom of the caster After moving, once moved, the bolts are adjusted to support and fix the structure. Therefore, the work of moving the structure and re-installing the structure after moving is complicated and requires a lot of manpower and labor. There were various inconveniences such as being.

[

After this, the opening / closing means d1 on the side of the supply line 11 of the hydraulic pressure supply and discharge means E opened as shown in Fig. 4 is closed so that the hydraulic pressure supply and discharge means E to prevent hydraulic pressure from flowing backward. Then, the structure 1 is rocked back and forth or left and right so that the hydraulic pressure in the cylinders 2 of the plurality of supporting means A is communicated with each other in accordance with the horizontal state If the level is completely controlled, the horizontal state is detected by the horizontal state detecting means H and the alarm means I is activated to alarm the state of the structure 1 being maintained in the fully horizontal state. At this time, The hydraulic pressure in the cylinder 2 of the receiving means A is fixed by stopping the flow of the hydraulic pressure in the cylinders 2 of the plurality of receiving means A by closing the connecting means F, The support angle 4 and the anti-vibration plate 5 provided on the piston 3 So that the structure 1 is firmly supported by the hydraulic pressure so as to be firmly supported on the ground and supported while being kept in a completely horizontal state.

In this case, when it is necessary to adjust the height of the structure 1 or to move the structure 1 by discharging the hydraulic pressure of the receiving means A, as shown in FIG. 5, Closing means d1 of the switching means D provided on the supply line 11 of the supplying and discharging means E is closed and the opening and closing means d2 on the side of the discharging line I2 is opened, The valve seat 13 of the valve means F is opened to allow hydraulic pressure in the cylinder 2 of the receiving means A to communicate with each other and then the piston b₂ of the pump means B is moved backward The hydraulic pressure that has entered the cylinder 2 of each of the receiving means A is sucked by the backward movement of the piston b2 of the pump means B, Is drawn to the discharge line (l2) side of the hydraulic supply and discharge means (E) through the connecting pipe (8) and the connecting pipe (12) The check valve (c4) of the valve means (C)

And the check valve c3 is closed so that the sucked hydraulic pressure is introduced into the cylinder b1 of the pump means B through the intake pipe b4 of the pump means B, When the piston b2 of the pump means B is advanced and the hydraulic pressure in the cylinder b1 is discharged through the intake pipe b4 as described above, the hydraulic pressure in the cylinder 2 of the receiving means A is discharged by repeating the operation of the oil pressure storing means G. [ It is possible to move the structure 1 by means of a moving means I such as a caster installed close to the supporting angle 4 and the vibration isolating plate 5 raised from the ground by raising the piston 3, The height of the structure 1 is adjusted.

In the present invention having such a constitutional principle, the hydraulic pressure is always supplied to the hydraulic pressure supplying and discharging means E, not only the supply and discharge line 11, but also all the hydraulic systems, except for the supporting means A, And the suction side g 1 and the suction side g 2 are formed in the hydraulic pressure storage means G so that the corresponding pressure is supplied and discharged when the hydraulic pressure is sucked and discharged by the pump means B Smooth operation.

The spring 6 mounted on the outside of the cylinder 2 of the receiving means A of the present invention is supported by the support cap 7 on the upper part so that the structure 6 And the spring 6 of the receiving means A as described above allows the hydraulic pressure in the cylinder 2 of the rowing means A to communicate with each other and to prevent the sprue 6 in the initial operation by the swinging operation of the structure 1. [ (6) to support the structure (1) to perform an auxiliary horizontal holding operation.

9 shows another modified embodiment of the receiving means A according to the present invention in that it is connected to the leveling valve means F to determine the height of the supporting angle 4 by receiving or discharging the hydraulic pressure, To the distribution pipe 8 of the leveling valve means F instead of the structure of the cylinder 2 and the piston 3 applied in the embodiment shown in Fig. The support angle 4 is formed in the lower part of the bellows pipe 16 in a cylindrical shape and the vibration plate 5 is fixed to the lower part of the bellows pipe 16, And then a spring 6 is inserted between the bellows pipe 16 and the support angle 4 so that a support cap 7 having a spring seat 7 ' And shows another embodiment of the means (A). In this case as well, the hydraulic pressure is supplied to or discharged from the bellows pipe 16 of the receiving means A by the pump means B, the hydraulic pressure supply / discharge means E and the hydraulic pressure regulating valve means F, It is needless to say that the horizontal holding and adjusting effect of the structure 1 and the effect of sucking the height of the structure 1 can be obtained in the same manner.
