The pin 120 may be configured to enable height adjustment within a setting range.

For example, it may have a structure that can appear vertically from the jig body 110 using hydraulic pressure, but it may be configured using a hydraulic cylinder or the like, and may be changed to a configuration that is obvious to a person skilled in the art.

The jig body 110 receives hydraulic pressure from the outside and lifts the pin 120 to a set height.

The jig body 110 has a shape surrounding the pin 120 and supports the circumferential surface of the pin 120 when the pin 120 is elevated and may serve to guide the elevation of the pin 120.

The hydraulic drive unit 400 may provide hydraulic pressure to the jig body 110.

For example, although not shown separately, the hydraulic drive unit 400 may be configured to include a hydraulic tank, a hydraulic line, an opening/closing valve, a pump, and the like, and may be changed to a matter that is obvious to a person skilled in the art.

The load detection sensor 200 detects a load applied to the pin 120.

Specifically, the load detection sensor 200 may be configured to include at least one load cell. At least one load cell may be located close to the tip portion 130 of the pin, through which the pin 120 when the pin 120 is in contact with the ship block 10 (see FIG. 3) when the pin 120 is raised. The load applied to the device can be accurately detected.

Preferably, the load detection sensor 200 may use at least two or more load cells, and in this case, more precise measurement may be possible using an average value of load values detected at different positions. However, the present invention is not limited thereto, and a single load cell may be used.

The controller 300 can detect the contact of the pin 120 with the ship block 10 by using the load detected by the load detection sensor 200, and detect the magnitude of the load applied to the pin 120. .

In addition, the controller 300 may control the hydraulic drive unit 400 to maintain a set load on the pin 120.

Meanwhile, a plurality of pin jig 100 may be provided (see FIG. 3 ).

Referring to FIG. 3, a plurality of pin jigs 100 are disposed below the ship block 10 connected to the crane wire 20.

As shown in (a) of FIG. 3, after the ship block 10 descends to a height at which the height of the pin 120 is adjustable, that is, a set range (at this time, the descending ship block is indicated by reference numeral 10'). 3), it may be configured to raise the pin 120.

In addition, the controller 400 may control the hydraulic driving unit 400 to simultaneously raise a plurality of pins provided in each of the plurality of pin jig 100 after the ship block 10 (see FIG. 3) descends.

In addition, the controller 400 is in the load detection sensor 200, at least one pin 120 of the plurality of pins 120 is in contact with the ship block 10, the set load is maintained on the contacted pin 120 When detecting, it is possible to control the hydraulic driving unit 400 to stop the rise of the contacted pin 120.

In other words, referring to (b) of FIG. 3, the pin of the first pin jig 100-1 contacts the ship block 10 in advance, and the controller 300 controls the hydraulic drive unit 400 to control the first pin. The rise of the pin of the jig 100-1 is stopped and the set load is maintained.

In addition, the controller 300 is a hydraulic drive unit to raise the remaining plurality of pins 120 except for the first contacted pin 120 until the entire plurality of pins 120 contact the ship block 10. 400).

If, in the load detection sensor 200, as shown in Figure 3 (d), the entire pins provided in the plurality of pin jig 100 are in contact with the ship block 10, and the set load on each contacted pin When this is maintained and the balance of the load is confirmed, the controller 300 outputs a crane wire 20 dismantling signal. Thereby, the operator can dismantle the crane wire 20 and place the plurality of pin jig 100, more specifically, the ship block 10 on top of the pin.

Next, a method for supporting a ship block using a pin jig device for supporting a ship block according to an embodiment of the present invention will be described.

2 and 3, the ship block support method uses the above-described ship block support pin jig device.

First, as shown in (a) of FIG. 3, a plurality of pin jigs 100 are arranged, and the ship block (or hull block) 10 is lowered to a predetermined height 10'. At this time, the ship block descends to a height range that can be contacted when the pin of the entire pin jig 100 is raised, that is, a set range (S100).

Next, referring to (b) of FIG. 3, a plurality of pins provided in the plurality of pin jig 100 rises toward the ship block 10. At this time, when the pins provided in the first pin jig 100-1 contact the ship block 10 first, the rise of the pins in contact with the first pin is stopped and the set load is maintained (S200).

Next, referring to (c) of FIG. 3, a plurality of pins provided in the remaining pin jig 100 are re-equipped with the exception of the pin jig 100-1 on which the load was applied in advance contact with the ship block 10. It rises toward the ship block 10. At this time, when the pin provided in the second pin jig 100-2 contacts the ship block 10 for the second time, the rise of the contacted pin can be stopped and the set load can be maintained. In this way, the process of raising the pin and maintaining the load is repeated until all of the pins provided in the plurality of pin jig 100 are in contact with the ship block 10 (see (d) of FIG. 3) (S300).

Meanwhile, referring to (d) of FIG. 3, it can be seen that all of the pins provided on the plurality of pin jig 100 are in contact with the ship block 10. In this case, after checking the balance of the load by detecting the load applied to each of the plurality of pins, the crane wire 20 is disassembled to stably place the ship block on the upper portion of the pin (S400).

As described above, according to the configuration and operation of the present invention, the process of pre-calculating the curved surface of the block shell plate and the height of the pin from the drawing information is not required, and a prior work of adjusting the height of the pin whenever the block is replaced is required. Can reduce production gaps.

Furthermore, it is possible to stably support the block by raising the pin on the block lowered to a sufficient height, away from the method of raising the block on the upper part of the pin jig set in advance, and to prevent damage and damage to the pin.

Furthermore, the hydraulic drive unit that drives the pin by hydraulic pressure and the load on the pin during hydraulic drive are measured to detect the contact between the pin and the block, as well as the stable support of the block by the pin using a load detection unit that detects the load of the pin. You can plan.

As described above with reference to the drawings illustrated for the present invention, the present invention is not limited by the embodiments and drawings disclosed in the present specification, and various by a person skilled in the art within the scope of the technical idea of the present invention. It is obvious that transformation can be made. In addition, even if not explicitly described and described the effect of the configuration of the present invention while describing the embodiments of the present invention, it is natural that the predictable effect by the configuration should also be recognized.
