The drive motor 400 is a known motor, is fixed to the shelf 300 via the bracket (b). In addition, when the rotation shaft 410 of the drive motor 400 is fixed to the shaft (not shown) of the pinion 321 and rotates, the pinion 321 is forcibly driven in the rotation direction of the rotation shaft 410. Therefore, when the driving motor 400 is operated, the pinion 321 is engaged with the rack 210 according to the rotation direction of the rotation shaft 410 is moved.

The first solenoid 510 and the second solenoid 520 are coiled (not shown) to form a coil spring (not shown) by spirally densely and uniformly cylindrically winding a coil spring (not shown) and the magnetic force is almost zero outside of the cylinder. And a magnetic force of relatively uniform size is formed inside, and when magnetized inside the cylinder, a magnetic plunger is arranged to be movable in the longitudinal direction of the cylinder through a coil spring fixed at one end thereof. As the magnetic force generated in the coil protrudes the plunger out of the cylinder and the electric power is cut off, the conventional solenoid moves to the inside of the cylinder by the elastic force of the coil spring. Here, the first solenoid 510 is inserted into and fixed to the first seating groove 221 formed at the left end of the seating table 220 (a of FIG. 5). Therefore, when the shelf 300 is rotated to the left side, the locking protrusion 322 is applied to the first plunger 511 that protrudes to the outside, so that the shelf 300 functions as a stopper. The rotated state is maintained as much as (b of FIG. 5). The second solenoid 520 is inserted into and fixed to the second seating groove 222 formed at the right end of the seating table 220. Accordingly, when the shelf 300 is operated in a state in which the shelf 300 is rotated to the right, the locking protrusion 322 is applied to the second plunger 521 protruding to the outside so that the shelf 300 functions as a stopper. As long as it is rotated.

The control unit 600 receives control signals from the first input unit 710, the second input unit 720, the third input unit 730, and the fourth input unit 740, and inputs the control signals. According to the control of the operation of the drive motor 400, the first solenoid 510 and the second solenoid 520. The control unit 600 according to the present invention, when the control signal is input from the first input unit 710, the drive motor 400 is rotated in a forward direction for a predetermined time to tilt the shelf 300 to the left, and then the rotating shaft The rotation of the 410 is stopped and the first solenoid 510 is operated. At this time, the locking projection 322 is caught by the first plunger 511, the shelf 300 is fixed to the left inclined. In addition, when the first button 711 is re-operated, the control unit 600 stops the operation of the first solenoid 510, inserts the first plunger 511, and then reverses the driving motor 400. Rotate for a certain time to return to the original position. When the control signal is input from the second input unit 720, the control unit 600 rotates the driving motor 400 in a reverse direction for a predetermined time, tilts the shelf 300 to the right, and then rotates the rotating shaft 410. Stop the rotation of the second solenoid 520 to operate. At this time, the locking projection 322 is caught by the second plunger 521 is fixed while the shelf 300 is inclined to the right. In addition, when the second button 721 is remanufactured, the power supply to the second solenoid 520 is cut off and then rotated in a forward direction for a predetermined time to return the shelf 300 to its original position. In addition, when the control signal is input from the third input unit 730, the power supply to the first solenoid 510 is always cut off, and when the control signal is input from the fourth input unit 740 to the second solenoid 520 Always cut off the power supply.

On the other hand, the driving time of the drive motor 400 is to calculate the time that the pinion 321 is sufficiently moved from the center of the rack 210 to the left end or the right end.

The first input unit 710 is operated so that the first button 711 is exposed to operate on the right inner wall surface of the concrete structure (H), the drive motor 400 is operated so as to operate at a constant speed for a predetermined time The control signal is output to the control unit 600. For example, when the first button 711 is pressed once to operate the first input unit 710, the driving motor 400 is rotated in the forward direction, and when the first button 711 is operated, the driving motor 400 is reversed for a predetermined time. Is rotated.

The second input unit 720 is operated so that the second button 721 is exposed to operate on the left inner wall surface of the concrete structure (H), the drive motor 400 is operated so as to operate at a constant speed for a predetermined time The control signal is output to the control unit 600. For example, when the second button 721 is pressed once and the second input unit 720 is operated once, the driving motor 400 is rotated in the reverse direction for a predetermined time, and when the second button 721 is operated again, the driving motor 400 is Rotate forward for a certain time.

The third input unit 730 is installed on the left inner wall surface of the concrete structure (H), corresponding to one end or the end of the shelf 300 "continuous to the shelf 300 spaced apart from the second input unit 720 The third button 731 is exposed on the left inner wall surface of the concrete structure H, and when operated, outputs a control signal of the first solenoid 510 to the control unit 600. Then, the control unit 600 ) Cuts power to the first solenoid 510, rotates the driving motor 400 in a reverse direction for a predetermined time, and returns the shelf 300 to the center of the concrete structure H.

The fourth input unit 740 is installed on the right inner wall surface of the concrete structure (H), corresponding to one end or the end of the shelf 300 ″ continuous to the shelf 300 spaced apart from the first input unit 710 The fourth button 741 is exposed and installed on the left inner wall of the concrete structure H, and when operated, outputs a control signal of the second solenoid 520 to the control unit 600. Then, the control unit 600 ) Cuts power to the second solenoid 520, rotates the driving motor 400 in a reverse direction for a predetermined time, and returns the shelf 300 to the center of the concrete structure H.

Referring to Figure 3, 4 and 6 to 9 the operation of the insulated underground distribution line connecting structure configured as described above are as follows.

As shown in FIG. 3, in the forming panel according to the present invention, when the underground distribution line C is normal or when the initial shelf 300 is installed, the shelf 300 is disposed at the center of the rack 210. The working standby state is installed to be able to rotate in both the left and right directions of the concrete structure (H). Therefore, in the connecting rod according to the present invention, the shelf 300 is disposed at the center so as to be spaced apart from both side walls of the concrete structure H, and water flowing along the left and right side walls even if a leak occurs in the concrete structure H 300 Because it does not flow into the underground distribution line (C) is protected from flooding and at the same time has an effect of extending the service life of the underground distribution line (C).

6, when installation and maintenance of the underground distribution line C are required in the right direction of the guide member 200, the first button 711 moves while pushing the shelf 300 to the left. ) Is reached, press it to output the control signal. When the control signal is input from the first input unit 710, the control unit 600 rotates the drive motor 400 in the forward direction for a predetermined time and stops. At this time, the pinion 321 disposed in the center of the rack 210 is forcibly driven by the driving motor 400 and is moved to the left end of the rack 210.

As shown in FIG. 7, when the pinion 321 is moved to the left end of the rack 210, the control unit 600 operates the first solenoid 510 to remove the first plunger 511. 1 protrudes to the outside of the mounting groove (221). Therefore, since the shelf 300 is rotated to the center of the rack 210 by the load, the locking protrusion 322 is caught by the protruding first plunger 511 and is kept in a fixed state while being inclined to the left. The passage P is formed to the right.

When the operation is completed, the first button 711 is pressed again. Then, the first input unit 710 cuts off the power supply of the first solenoid 510 to the control unit 600 so that the first plunger 511 inserts a signal into the first seating groove 221. Enter it. Then, the control unit 600 cuts off the power supply to the first solenoid 510, rotates the drive motor 400 in the reverse direction for a predetermined time to return to the original position. Therefore, in the connecting rod according to the present invention, the first solenoid 510 in a state in which the shelf 300 is rotatably disposed in both left and right directions at the center of the rack 210 is rotated to the opposite side of the direction in which the shelf 300 is to be worked. And when the shelf 300 is fixed by operating the second solenoid 520, the passage (P) is formed, there is no need to secure a separate space for the passage (P) unnecessary space is omitted, so the utilization of the space is improved There is also an effect that the size of the concrete structure (H) is optimized.

In addition, when the underground distribution line (C) is arranged on the left side of the concrete structure (H), or when the passage (P) is formed on the left side for maintenance, the second method is performed in the same manner as the first input unit 710. It operates by operating the input unit 720, it is shown in Figures 8 and 9, the description thereof will be omitted.

On the other hand, as shown in Figure 4, it is assumed that the connecting rod is formed as a unit of 'A', the connecting rod continuous to this 'B'. At this time, the work proceeds from 'B' to 'A', if the shelf 300 included in the 'A' is not in its original position, the work becomes cumbersome. For example, the shelf 300 is fixed to the left side at the time of the previous work, and 'A' is a state in which a passage P is formed to the left and is fixed, and the passage P is currently fixed to the right of 'A'. You have to work while forming. At this time, when the worker forms a passage (P) from the 'B' to the right side and wants to move to the 'A' side, the passage (P) because the shelf 300 of the 'A' is inclined to the right. I can't help but stop working. At this time, by pressing the fourth button 741 installed on the right inner wall surface of the concrete structure (H) corresponding to the end of the shelf (300) of the 'B' by pressing the fourth button 741 to cut off the power supply to the second solenoid 520 to the second plunger Inserting the 521 into the second seating groove 222 and rotating the driving motor 400 in the forward direction for a predetermined time, the shelf 300 is returned to its original position. Then, when the second button 721 is pressed again, Since the shelf 300 is inclined to the left side and fixed to the left side, a passage P is formed on the right side. Therefore, in the insulating underground distribution line connecting rod according to the present invention, the connecting rod 'A' is disposed at the center of the concrete structure H during operation. Even if it is not, since the 'A' shelf 300 can be repositioned at one end or the end of the shelf 300 "of the continuous connecting table 'B', even if the shelf 300 is fixed to one side in the existing work, the concrete structure ( It is possible to return the shelf 300 to the center of the H), the line Even if the class 300 is not in the home position, there is an effect that the operation can continue without interruption.
