Pin jig for supporting the block of a hull}

The present invention relates to a pin jig for ship block support, and more particularly, a plurality of pin holes formed to penetrate the lifting bar of the pin jig in a zigzag direction in a 90 ° direction, so that the lifting bar is buckled. In order to improve the endurance force (bearing force) and to stop the height of the elevating rod, the stopper for temporarily stopping the height of the elevating rod is plunger type. Forming a see-through hole to check the position of the hole, the stopper's plunger is easily inserted into the other pin hole to check the position of the pin hole through the see-through hole so that the height of the lifting bar can be easily adjusted. When supporting the ship block as a pin jig by installing an inclination adjusting device that can adjust the angle of the pin jig to be placed on the bottom of the ship By supporting the lock is always perpendicular prevent buckling of the pin jigs and intended to be able to support the vessel safely block.

Conventional pin jigs include Patent Application No. 2003-99024 (Prior Invention 1), Patent Application No. 2003-99025 (Prior Invention 2), Patent Application No. 2004-90718 (Prior Invention 3), and Patent Application No. 2005-990 The inventions of 354 (Prior Invention 4) and Patent Application No. 2005-61022 (Prior Invention 5) exist.

The common structure of the prior invention 1 to 5 of the prior invention is a fixed support is installed vertically on the base of the work place for manufacturing a ship, and is installed to be installed in the vertical support to move up and down in a plurality of up and down length direction Pin holes are formed at regular intervals and is made of a lifting rod to adjust the height of the pin jig as the fixing pin is inserted.

However, since the plurality of pin holes formed in the elevating rods are formed only in one direction in the vertical direction, the portions in which the plurality of pin holes are formed at regular intervals are buckled rather than the portions where the pin holes are not formed. There is a problem of weakening the load.

For reference, the dimensions of the lifting rods used by domestic shipbuilders are 100-200cm long, 70-80mm outer diameter, and 60mm gap between the pinholes. It is manufactured and supplied.

In this situation, as the pinhole is formed only in one direction, the portion where the pinhole is formed is weakened by the buckling load, and abnormal load is applied to the pin jig in which the lifting bar is installed, or for a long time. It had a fatal problem that the part which formed the pinhole by use bends and finally bends.

In addition, as shown in FIG. 1, the inclined bottom portion of the ship block 3 (shown by a circular arc in the figure) is supported by the pin jig at the portion where the inclined bottom of the ship block is in contact with the tip of the pin jig. The load is concentrated in the perpendicular direction F3. The pin jig 1 is always installed on the base 2 only in the vertical direction F2, so that the load of the ship block 3 is at the distal end of the pin jig. A plurality of pin jigs supporting the inclined bottom portion by the force of pushing the tip portion of (1) outward (F1) do not properly support the load that each pin jig can support, and in severe cases, the pin jigs The front end of the can be separated in the outer direction (F1), or the lifting bar 20 can be rotated outward. Therefore, as the plurality of pin jigs supporting the inclined bottom of the ship block do not properly support their respective loads, the rest of the pin jigs, except for the pin jig supporting the inclined bottom, are the result of supporting the heavy ship block as a whole. The support is concentrated on each pin jig so that the support capacity of the dozens of pin jig weakens the support force of each pin jig weakened. This would be the same as holding the fork lifter at an angle when the fork lifter is held vertically from the ground when the fork lifter is supported by the fork lifter.

However, it is natural that the elevating rod having a pin hole only in one direction while the tip of the elevating rod is in contact with the rounded or inclined bottom of the starting block in the inclined direction T will have a greater degree of bending. .

In addition, the conventional invention is to install the handle or motor in the device portion for raising and lowering the elevating rod, and to apply the means such as using a roller and a wire to move the linear movement up and down linear movement, they raise and lower the elevating rod Device parts such as a steering wheel, a motor, and a roller to operate have a problem that the structure is complicated, the operation is cumbersome, and the manufacturing cost is increased.

The present invention is to solve the above problems by forming a plurality of pin holes formed in the lifting bar in the zigzag direction of 90 ° direction to improve the strength of the lifting rod to withstand the buckling load, and temporarily stop the lifting rod on the fixed support While the stopper is installed, the stopper's plunger can be easily inserted into the pin hole on the other side while checking the position of the pin hole on the other side, so that the height of the elevating rod can be easily adjusted. The purpose of the inclination control device to adjust the angle is to support the ship block vertically when supporting the ship block as a pin jig to prevent the buckling of the pin jig and to securely support the ship block.

The present invention for achieving the above object is inserted into the lifting rod formed with a plurality of pin holes at regular intervals in a fixed support that is installed vertically on the base of the workshop for manufacturing a vessel, the fixing pin is fitted in the pin hole In the pin jig for ship block support for adjusting the height of the elevating rod in the vertical direction, the pin hole is formed alternately in the zigzag direction of the 90 ° direction, the perspective hole for checking the pin hole in the upper portion of the front of the fixing support And a stopper through which a through hole is formed in the fixing support in the 90 ° direction of the see-through hole, and a stopper in which the plunger is inserted into the inside of the through hole through the through hole and elastically inserted into the pin hole. However, the stopper is installed so that the housing protrudes outward in the center of the flange portion is installed on the outer surface of the fixed support, Portion, and elastically supported by the rear end the spring is characterized in that the plunger is inserted into the inside of the front end portion through-hole pin is installed elastically inwardly.

As described above, the pin jig for ship block support of the present invention has a plurality of pin holes formed in the elevating rod in the zigzag direction in the 90 ° direction, so that the elevating rod can withstand the buckling load, thereby improving the force. The stopper for temporarily stopping the elevating rod is installed on the fixed support, while the plunger of the stopper is easily inserted into the other pin hole while checking the position of the pin hole on the other side of the fixed support, so that the height of the elevating rod can be easily adjusted. will be.

In addition, by installing a tilt adjusting device that can adjust the angle of the pin jig on the bottom of the fixed support, when the inclined bottom of the ship block is supported as a pin jig, the inclined bottom of the ship block and the tip of the pin jig are always perpendicular to each other. When the bottom surface of the ship block is rounded or inclined by supporting in the direction F3, the pin jig supports the portion in which the load is concentrated in the direction perpendicular to the inclined portion at an angle corresponding thereto. It is to compensate for the weakening of the bearing capacity for the part that explained the conventional problem with reference to 1, whereby each (several dozens) of pin jigs supporting the bottom of the ship block distributes the load of the ship block evenly. Given this, the overall bearing capacity is increased compared to the conventional one, and the bearing force for supporting each pin pin is increased. This means that when the fork lifter is inclined when the fork is lifted up, the fork lifter does not fall and effectively supports the fork.

Referring to Figures 1 to 8 the working relationship of the present invention configured as described above is as follows.

First, an embodiment of the present invention will be described with reference to FIGS. 1 to 6.

1, a plurality of pin jigs 1 are installed vertically on the base 2 so that the ship block 3 to be worked as shown in FIG. 1 can be placed for the production of the ship. In this case, the bottom of the ship block 3 to be placed The height of the lifting bar 20 is adjusted to suit the shape.

In order to adjust the height of the pin jig (1) by holding the lifting bar 20 up and down with the fixing pin (4) in the pin hole 21, the plunger 15 of the stopper 14 ) Is elastically in contact with the outer surface of the elevating rod 20 from the inside of the fixed support 10 by the elasticity of the spring 16, or the pin portion 15a of the plunger 15 in the pin hole 21 Even when elastically contacted, if the force for raising or lowering the elevating rod 20 is stronger than the elasticity of the spring 16, the tip pin portion 15a of the plunger 15, which has been inserted into the pin hole 21, becomes the pin hole 21. ) To move up and down the lifting bar 20 can be lifted or rotated.

When the lifting pin 20 is raised or lowered to the height to be adjusted while holding the lifting bar 20 by hand, the tip pin portion 15a of the plunger 15 coincides with the pin hole 21 of the height to be adjusted. The plunger 15 is inserted into the pin hole 21 corresponding to the plunger 15 by elasticity in the spring 16 installed inside the housing 17.

When the plunger 15 is to be matched with the pinhole 21 of the height to be adjusted as described above, the pinhole 21 is inserted into the fixing support 10 because the pinhole 21 to be fitted is inserted therein. Although it will not be easy to adjust the position of the 21, in the present invention, a see-through hole 13 for confirming the position of the pin hole 21 is formed in the upper portion of the front surface of the fixed support 10.

Therefore, the operator supports the fixed support 10 while aligning the front and rear pin holes 21a of the lifting rod 20 exposed upwards of the fixed support 10 in a straight line with the sight hole 13. When the front and rear pin holes 21a of the lifting rods 20 inserted into the inner side of the lifting rod 20 are visible through the see-through hole 13, the plunger 14 of the stopper 14 provided on the outside of the see-through hole 13 in the direction perpendicular to the see-through hole 13 15 is positioned in line with the left and right pin holes 21b so that the plunger 15 of the stopper 14 is elastically inserted into the left and right pin holes 21b located inside the fixing support 10 without difficulty. You can do it.

The state in which the plunger 15 of the stopper 14 is inserted into the pinhole 21 of the height to be adjusted as above is to temporarily adjust the height, and after visually confirming that the temporarily adjusted height is correct, the height is adjusted. If it does not match the height of the lifting rods 20 in the same manner as above, and if the height is temporarily adjusted to fit the fixing pin (4) hanging on the connecting chain (5) as shown in Figure 3 The pin hole 21 is firmly fixed to the lifting bar 20.

Put the vessel block 3 of the heavy weight to the top of the pin jig (1), the height of which is adjusted after fixing the lifting bar 20 firmly by pinching the pin hole 21 on the fixing support 10 as described above. If the upper part of the support head 23 is not correctly placed on the ship block 3, the support head 23 may be re-adjusted while adjusting the height of the support head 23 by unscrewing or tightening the support head 23. If the upper end of the ship block (3) to accurately support the bottom is to complete the installation and adjustment of the height of the pin jig (1).

For reference, the weight of the elevating rod 20 is 10-15kg, so when the height of the elevating rod 20 is temporarily adjusted as described above, the work is held when the elevating rod 20 is raised or lowered by hand. It is not difficult, and when the plunger 15 of the stopper 14 is inserted into the pin hole 21 of the elevating rod 20, the plunger 15 can fully support the elevating rod 20 so that it does not descend.

The following is a description of another embodiment shown in FIGS. 7 and 8, which is a direction perpendicular to the inclined bottom of the ship block 3 when the bottom of the ship block 3 is formed in an arc shape or is formed to be inclined. When the tip of the elevating rod 20 is supported by (F3) to support the inclined bottom surface of the ship block, the pin jig supports in a straight line correspondingly that the load is concentrated in the perpendicular direction at the inclined support. It is for the pin jig 1 not to bend without the support force of the pin jig 1 falling.

Therefore, another embodiment is to be able to adjust the installation angle of the angle of the pin jig (1) is set up in accordance with the degree of inclination or inclination of the bottom surface of the ship block (3).

At this time, the inclination of the bottom support plate 31 is adjusted by the lower hinge portion (up and down hinge brackets 36 and 33 and hinge pins) as the support bolts 34 installed downward on both sides of the bottom support plate 31 are loosened and tightened. And, as the pin jig (1) consisting of the lifting bar 20 and the fixed support 10 is installed vertically on the top of the bottom support plate 31 that is inclined so that the inclination angle of the pin jig (1) can be adjusted It is.

As described above, even when the bottom of the ship block 3 is arc-shaped or inclined, the pin jig 1 always supports the bottom of the ship block 3 vertically with respect to the inclined bottom of the ship block. The load of the ship block acts in a straight line in the vertical direction of the pin jig 1 to prevent the bending of the pin jig and to support the ship block 3 with a large supporting force, which is to pin the jig bottom of the ship block. In the part supported by the pin jig, the load of the ship block is concentrated in the right angle direction (F3) that the pin jig supports, so that the pin jig is supported in a straight line corresponding to the direction in which the load is concentrated. The three pin jigs fully support the load that can be supported, and in the conventional case shown in FIG. 1, the plurality of pin jigs supported on the inclined ground do not properly support the load each will support. In the present invention, the bearing capacity is lowered. F1 shown in Figure 7 indicates that the load of the ship block acts in the outward direction, F2 indicates that the load of the ship block acts in the vertical direction of the lower side, and the combined force of F1 and F2 is concentrated in the F3 direction As the pin jig is installed in the F3 direction, the pin jig does not slip or fall to fully support the load of the ship block.

In addition, when the pin jig 1 is erected vertically or inclined by forming a long long hole 32 in the vertical direction of the hinge pin hole into which the hinge pin 35 is inserted, the pin jig 1 is formed in the downward hinge bracket 33. The bottom surface of the downward hinge bracket 33 is in contact with the upper surface of the base plate 37 as the pin jig 1 is lowered by the weight of the ship block 3 mounted on the upper side of the pin jig 1 and the weight of the ship jig 1. Will be.

As the bottom surface of the downward hinge bracket 33 is contacted and supported without being spaced apart from the upper surface of the base plate 37, the heavy weight of the ship block 3 acts on the pin jig 1, There is no problem with support.
