Description

TECHNICAL FIELD [0001] The present invention relates to a computer hydraulic pressure tuning system having a hydraulic pressure jack and a three-axis tilt system for restoring and raising a structure, and a method thereof. BACKGROUND OF THE INVENTION FOR THE SAME}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a position restoration and pull-up of a structure, and more particularly, to a hydraulic jack having a horizontal system for checking the horizontal position of a hydraulic jack for restoring a damaged structure or lifting a structure, (X, y, z) inclinometer including a direction (x axis) tiltmeter, a vertical direction (y axis) tiltmeter and a forward and backward direction (z axis) tiltmeter .

Generally, bridge structures are inevitably damaged due to frequent passage of heavy heavy vehicles or trains due to the characteristics of bridges and aging due to prolonged progress. Particularly, bridge supports installed at bridge piers and alternations are structurally important members that appropriately absorb the load on the bridge and transmit it to the substructure. Damage and breakage often occur due to excessive impact. Accordingly, the position of the bridge structure can be moved vertically, horizontally or back and forth for proper maintenance and reinforcement of the bridge structure.

In addition, when the bridge is located on the river, there is a case where the cross section of the water passage is insufficient due to the deposition of the gravel and the environment, and the bridge superstructure, for example, the bottom plate or the girder is to be pulled up.

In order to repair and reinforce maintenance of such bridges, it is necessary to move the bridges and move the bridges evenly or unevenly to the top, bottom, right and left, front and back.

In addition, large-scale structures in industrial fields such as shipbuilding and other plants other than the construction field may need to be moved appropriately according to the progress of the transportation work. For example, it may be necessary to extrude the ship after the ship is dry, and to install the roof of the plant after installing the column.

However, conventional movements of large structures such as bridges are mainly used by manually connecting hydraulic jacks to hydraulic pumps by hydraulic hoses. It is difficult to expect precise operation, and simultaneous impression or uneven impression is impossible, and in particular, when the structure is damaged, it becomes very dangerous. That is, according to the conventional technique, it is impossible to precisely measure and control the horizontal inclination of the hydraulic jack, the working load, the pressure, the displacement amount, and the like. In addition, it is practically impossible to control the movement of the large structure at a long distance.

In addition, a large amount of manpower must be input for the operation and maintenance of the work, and maintenance is not practically carried out at night, which may lead to a great accident at all times.

In the case of bridges, there is no control and control function for momentary load change because the load condition is changed from time to time as the vehicle and train continue to pass through the upper traffic load. If the risk situation is predicted, Despite the fact that it should be in operation, there is no such function. In addition, since there is no remote communication system, it is possible to control and maintain only in the field.

In order to overcome many problems of the conventional manual hydraulic operating system according to the related art, there is a need for a hydraulic operating system capable of performing safe automatic measurement and control and efficient remote communication and management.

1 is a view for explaining damage to a structure according to a conventional technique. FIG. 1 (a) shows a structure before a damage, and FIG. 1 (b) shows a damaged structure.

The upper structure 12 to be moved to the restoration position by using the hydraulic jack 13 in the case of the damage of the structure according to the conventional technique is moved to the lower structure 11 And it is determined that the position of the structure 12 has been moved even if the lower structure 11 sinks to generate a vertical displacement amount.

FIG. 2 is a view for explaining cracks in a structure due to a load and rotation of an upper structure according to a conventional technique. FIG. 2 (a) is a front view, and FIG. 2 (b) is a side view.

2, the bridge is composed of a lower structure 21 made up of alternating and pierced bridges, and an upper structure 22 composed of a girder and a bottom plate installed across the upper part, and the lower structure 21 of the bridge, And the upper structure 22 is lifted by using the hydraulic jack 240 according to the movement amount measured by the displacement gauge 25. [

Specifically, the upper structure 22 is supported and fixed by a support device 23 installed on the upper side of the pier, so that the upper structure 22 can be expanded or contracted according to the expansion and contraction stress acting on the upper structure 22 after the construction.

As shown in FIG. 2 b), these bridges are naturally aged after a long period of time after construction, or are cracked or damaged due to artificial factors in the lower structure 21, the upper structure 22, the support device 23, And the upper structure 22 installed on the upper portion of the lower structure 21 is pulled up by the hydraulic jack 24 to repair and replace each component portion of the bridge where cracks or breakage have occurred. For example, when the pulling load is P, cracks are generated by the horizontal load P ', and rotation of the upper structure 22 may occur.

The hydraulic jack 23 is placed in a space between the support surface of the lower structure 21 and the girder of the upper structure 22 and then the hydraulic jack 23 The hydraulic jack 23 is operated in a state of supporting the girder and the upper structure 22 is lifted while maintaining the upper level with the support surface of the upper part of the lower structure 21 as a fulcrum, The lower structure 21, the upper structure 22, the supporting device 23,

At this time, when the hydraulic jack 24 is installed, the upper structure 22 maintains the horizontal by keeping the hydraulic jack 24 tilted in order to keep the horizontal structure. However, the lower structure 21 is provided with the hydraulic jack 24 And measuring it in the oil phase. As a result, damage may occur to the lower structure 21, and a rotational force is generated when the upper structure 22 is moved, so that the abnormal deformation amount of the upper structure 22 is generated.

According to the conventional technique, an inclinometer can be mounted on the hydraulic jack 24 to confirm and maintain the vertical displacement of the structure, and the tuning control proceeds only with vertical displacement and load. That is, according to the conventional technique, the load according to the displacement is applied when the structure is moved, and the tuning control is proceeded with the vertical displacement and the load.

On the other hand, as a prior art, Korean Patent No. 10-415766 discloses an invention entitled " Bridge Structure Positioning Computer Control System ".

The bridge structure moving computer control system according to the related art is a system for lifting a large structure such as a bridge structure, an iron structure, a ship, etc., and is provided with a plurality of Hydraulic jack; A plurality of hydraulic jacks connected to each other through an oil supply line, and an oil pump connected to each of the oil pressure jacks for measuring a measurement value of at least one of a lower load, a shearing displacement amount, a horizontal inclination, Measuring means; Solenoid valve means provided on an oil supply line for controlling operation of each of the hydraulic jacks; And control means for controlling the operation of the solenoid valve means while processing the measured values inputted from the measuring means.

The bridge structure moving computer control system according to the related art can move the position of a large structure uniformly or irregularly by automatic control according to necessity, thereby reducing the number of workings, greatly improving the stability and efficiency, Control system, it is possible to perform safe automatic measurement and control of large structures, steel structures, ships, etc., and efficient remote communication, thereby reducing the occurrence of large-scale accidents, enabling constant management, An impression work can be performed.

However, in the case of a conventional computer control system for moving a bridge structure, it is difficult to expect a stable impression because the bridge structure is not stably supported while the bridge structure is stably supported. There is a problem in that it is not easy to restore and raise the position corresponding to the rotational displacement of the bridge structure.
