Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a connection jig for a turn-over jig and a turn-

The present invention relates to a turn-over method, and more particularly, to a turn-over jig for a turn-over jig, which enables a stable turning-over of a structure by connecting a turn- And a turn-over method using the same.

Generally, a structure made of a heavy body can be turned upside down for backside work, and when the work on the backside is completed, a turnover operation is performed to turn over again using a crane for subsequent work such as mounting.

12 to 17 are flowcharts sequentially illustrating a turn-over process using a conventional turn-over jig.

The turnover method of the conventional structure is such that the turnover jig 20 is rotated in the state in which the structure 10 is turned upside down on the support block 1 as shown in FIG. The main cable C1 and the auxiliary cable C2 connected to the crane are connected to both ends of the structure 10 as shown in Fig. 14, Lift the turn-over jig (20).

The auxiliary cable C2 connected to the erected structure 10 in which the main cable C1 is moved forward and the structure 10 is rotated by turning the turn-over jig 20 as shown in FIG. 15, So that the turn-over jig 20 is connected to the first connection part 11 connected thereto.

16, the structure 10 is lifted and separated from the turn-over jig 20, and then the main cable C1 is moved forward and downward to raise the auxiliary cable C2, Causing the structure 10 to turn over.

In the turnover method using the conventional turnover jig 20 as described above, when the structure 10 is lifted through the main cable C1 as shown in FIG. 15, The connecting point between the over jig 20 and the first connection part 11 acts as a center of gravity of the structure 10. At this time, the structure 10 is located at a position where the lower frame 13 is located near the vertical state The connection point between the main cable C1 and the second connection portion 12 of the structure and the connection point between the turnover jig 20 and the first connection portion 11 of the structure are close to a vertical state A sudden change in the center of gravity of the structure 10 occurs, causing problems such as vibration and bounding.

Conventionally, in order to stably maintain the structure, the structure 10 is inclined in the rotational direction beyond the vertical state (about 9 degrees). At this time, the structure 10 is tilted in the rotation direction The auxiliary cable C2 has to be connected to the vertical frame of the structure and the tension of the auxiliary cable C2 has to be precisely adjusted and maintained as shown in Fig. 14 in order to cope with a sudden change of the center of gravity when passing the vertical state in the process.

However, in order to stabilize the structure 10 as described above, the tension of the auxiliary cable C2 is required to be controlled so that the structure 10 is stabilized in the vicinity of the vertical state, and the operation time is accordingly increased .

In the process of reconnecting the auxiliary cable C2 to the structure 10, the structure 10 inclined in the rotational direction is in a state in which the center of gravity of the structure 10 is biased in the rotating direction, There is a problem that a considerable force corresponding to the weight of the structure 10 is transferred to the main cable C1.

In addition, in order to stabilize the structure in the standing state as a whole and reconnect to the first connection part 11 of the auxiliary cable C2, the standing structure 10 is tilted in the rotational direction past the vertical state A situation in which the center of gravity of the structure 10 changes abruptly is always generated according to necessity, and the risk of the turnover operation of the structure has to be taken into consideration.

Hereinafter, embodiments of a turn-over jig and a turn-over method using the same according to the present invention will be described in detail with reference to the accompanying drawings, wherein like reference numerals refer to like elements And redundant explanations thereof will be omitted.

1 is a perspective view showing a connecting jig 30 for a turn-over jig according to an embodiment of the present invention. 2 is a front view showing a connecting jig 30 for a turn-over jig according to an embodiment of the present invention. 3 is a partially enlarged view showing a state in which a connecting jig 30 for a turn-over jig is installed on the structure 10 according to an embodiment of the present invention.

1 to 3, a connecting jig 30 (hereinafter abbreviated as 'connecting jig') for turning over jigs according to an embodiment of the present invention includes a connecting jig 30 The rotation point which is the center of gravity of the structure 10 is positioned on the rotation direction side of the connection point between the main cable C1 and the second connection portion 12 of the structure 10 when the structure 10 is standing, It is possible to perform a stable turnover of the structure 10 by preventing the abrupt change of the center of gravity of the structure 10 even if the structure is in a state close to the vertical state.

The connecting jig 30 includes a first connecting block 31 rotatably connected to the turnover jig 20 and a second connecting block 31 connected to the first connecting block 31 to be integrally formed and connected to the structure 10 And a second connection block 34 as shown in FIG.

A first coupling lug 32 is formed at one side of the first coupling block 31 to be rotatably connected to the turnover jig 20 and a first coupling lug 33 is connected to the auxiliary cable C2, Can be formed.

Specifically, the first binding lug 32 may be formed to be biased to one end lower side of the first connection block 31 on the basis of the state shown in FIG. 2, and may be formed so as to protrude in one lateral direction have. In addition, the first binding lug 32 may be formed with a connection hole 32a to be connected to the coupling block of the turnover jig 20 by a pin.

The first connection lug 33 may be formed on the upper side of the first connection block 31 and may be formed to be biased to the other end (the right side in the figure) opposite to the one end of the first binding lug 32 . In addition, the first connection lug 33 may be formed with a connection hole 33a to be connected to the auxiliary cable C2 of the crane and connected to the pin. The first connection lug 33 may be connected to the auxiliary cable C2 so that the connection jig 30 can be lifted and moved by the auxiliary cable C2.

On the other hand, the second connection block 34 is perpendicular to the first connection block 31 at a position deviated from the other end of the first connection block 31, The second connection block can be connected in the longitudinal direction). The second connection block 34 is provided with a second binding lug 35 connected to the first connection part 11 formed at the lower end of the structure 10 and a second binding lug 35 connected to the standing and standing structure 10 The second connection lug 36 may be formed to be connected to the auxiliary cable C2.

At this time, the second binding lug 35 and the second connecting lug 36 are formed in a structure corresponding to the first binding lug 32 and the second connecting lug 33 described above, . Specifically, when the first binding lug 32 is protruded in the left direction, the second binding lug 35 is formed in a symmetrical structure protruding rightward, and the first connecting lug 33 protrudes upward The second connection lug 36 may be formed to protrude downward.

The length of the second connection block 34 may be set to a minimum range according to the position of the connection point to which the structure 10 and the main cable C2 are connected. The main cable C1 and the structure 10 are connected to each other in order to prevent a sudden change in the center of gravity in a state in which the structure 10 approaches the vertical state when the structure 10 stands up during the turn- The connection point of the structure 10 may not be aligned with the rotation point formed by the connection jig 30 and the turnover jig 20. In this case, (The rotation point is located in the lower rotational direction of the lower frame 13 of the minimum structure in the rotation of the structure 10).

When the position of the second connection part, which is the connection point between the structure 10 and the main cable C1, is formed on the lower side of the structure lower frame 13 as in the conventional case, the length of the second connection block 34 is in a specific range The rotation point of the structure is always positioned in the rotational direction with respect to the connection point between the main cable C1 and the second connection portion so that even if the structure 10 approaches the vertical state, A sudden change in the center of gravity does not occur.

On the other hand, when the position of the second connection portion is formed on the upper side of the structure lower frame 13, the connection point between the rotation point of the structure 10 and the first connection portion 11 and the second connection lug 35 The interval T2 between the points can be formed to be equal to or greater than the thickness T1 of the structure lower frame 13. [

That is, the minimum length of the second connection block 34 is set such that the interval T2 between the rotation point of the structure and the connection point at which the second coupling lug 35 and the first connection portion 11 are connected is smaller than the minimum bottom frame thickness length T1 is greater than the connection point between the main cable C2 and the structure 10, a rotation point corresponding to the center of gravity is located closer to the rotation direction than the connection point between the main cable C2 and the structure 10, The center of gravity of the structure 10 does not change abruptly, so that phenomena such as vibration and bounding do not occur. Accordingly, it is not necessary to tilt the structure 10 in the rotation direction for stabilization of the structure 10, and the load burden applied to the main cable C1 supporting the tilted structure can be reduced.

Hereinafter, a turning-over method using the connecting jig 30 for the turn-over jig will be described.

4 to 10 are flowcharts sequentially illustrating a turn-over process according to an embodiment of the present invention. 11 is a flowchart of a turn-over method of a structure using a connection jig for a turn-over jig according to an embodiment of the present invention.

Referring to FIGS. 4 to 11, first, as shown in FIG. 4, the structure 10 is placed in an inverted state on a plurality of support blocks 1 in order to carry out a process such as design work. The structure includes a first connection part 11 for connecting the connection jig 30 and second connection parts 12a and 12b for connecting the main cable to the both sides of the lower frame 13 of the structure Is installed. The second connection portions 12a and 12b may be formed on the bottom surface or the top surface of the lower frame 13 but the second connection portions 12b may be formed on the upper surface of the lower frame 13 ) Will be described as an example.

5, the connection jig 30 is attached to one side of the structure 10 supported by the plurality of support blocks 1 for the turnover operation of reversing the structure 10, as shown in FIG. 5, (Step S1). At this time, the connection jig 30 is installed by connecting the auxiliary cable C2 to the first connection lug 33 of the connection jig 30 to move the connection jig 30 to the lifting and structure side, The connecting jig 30 is installed on the structure 10 by connecting the second binding lug 35 to the structure side first connecting portion 11 while the second binding lug 35 and the first connecting portion 11 are connected to the pair So that they are not mutually rotated by the pins.

When the connection jig 30 is installed on one side of the structure 10, the main cable C1 of the crane is connected to the second connection portion 12b formed on the lower frame 13 as shown in FIG. 6, The coupling block 21 of the turnover jig 30 and the first coupling lug 32 of the coupling jig 31 are rotatably connected after the structure is lifted a predetermined height through the main cable C2 and the main cable C1 (Step S2)

 Next, when the connection between the turn-over jig 20 and the connection jig 30 is completed, the auxiliary cable C2 connected to the connection jig 30 is disconnected as shown in FIG. 7, and then the main cable C1 is lifted And moves in the direction of rotation (turnover) to stand the structure 10 (step S3). At this time, the connecting point between the main cable C1 of the standing structure 10 and the structure 10 is determined by the length of the second connecting block, even if the structure 10 is in a state of being close to a vertical state or slightly inclined in a rotating direction And is positioned within a range not exceeding the rotation point of the structure 10 in the rotation direction. (I.e., the rotation point of the structure 10 is positioned on the left side of the connection point between the main cable C1 and the structure 10 when the structure is standing as shown in FIG. 7).

In other words, even if the structure 10 stands upright when the structure 10 is standing by the main cable C1, even if the structure 10 is in a state of approaching to the vicinity of a vertical state or near a vertical state and in a state of being slightly inclined beyond a vertical state, The situation where the abrupt center of gravity of the structure 10 is changed does not occur because the rotation point exists on the rotational direction side of the connection point between the main cable C1 and the structure 10. [ Therefore, there is no need to finely adjust the tension of the main cable C1 and the auxiliary cable C2 as in the prior art, so that the structure can be stably and quickly turned up and turned over. In addition, since the structure can stand upright, the load of the structure 10 is dispersed in the turnover jig 20, so that the load burden applied to the main cable C1 can be minimized.

8, the auxiliary cable C2 is connected to the second connection lug 36 of the connection jig 30. When the auxiliary cable C2 is connected to the second connection lug 36 of the connection jig 30, 20 and the connecting jig 30 are separated from each other and then the main cable C1 is lifted to float the structure 10. In step S4,

When the structure 10 is separated from the turnover jig 20 and lifted up, the main cable C1 is moved forward and downward as shown in Fig. 9, and at the same time, the auxiliary cable C2 is lifted, (S5)

10, when the structure 10 is completely turned over, the main cable C1, the auxiliary cable C2 and the connecting jig 30 are separated from the structure 10 to perform the turnover operation of the structure 10 (Step S6)

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It will be understood that the invention may be varied and varied without departing from the scope of the invention.
