Description

Ship block support {apparaus for supporting a block of ship}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a ship block support, and more particularly, to a ship block support in which the structure is improved so that a load applied to a ship block support is measured and compared with a calculated load value to maintain a stable posture of the block .

Conventionally, a column-shaped support pipe support is used in order to support a ship block during vessel drying and to prevent their conduction.

However, in the case of RUDDER HORN BLOCK, which has a severe bending of the surface, it is necessary to weld the support pipe to the ship block in lifting operation with the Goliath crane in order to mount the ship block. And it is necessary to lay down this whole body to the ground again. Therefore, the utilization efficiency of the Goliath crane equipment is considerably deteriorated due to the lifting operation. [2] Due to the unsupported lower support structure of the support pipe, Which is likely to cause accidents, and (3) it takes a long time to set the ship block as a whole.

When using a heavy equipment such as a forklift to move a block support, or moving a support by tilting the support in case of a small block, there is a high risk of injuring a worker in the event of a conduction accident.

In addition, screw screw type screw type is widely used for adjusting the height of the block supporter. However, in the state of receiving the force of the nut, the nut type regulating device does not turn and breakage is difficult and fine control is difficult.

However, when the hydraulic hoses and cylinders are broken, it is often difficult to keep the position of alignment, which makes the application difficult because of the high risk of safety accidents. In addition, due to the characteristics of hydraulic pressure, it is difficult to keep the fixed posture continuously due to the minute hydraulic pressure leaking when the block is supported for a long time.

As a representative example of the prior art, Korean Patent Registration No. 10-0998112 discloses a structure in which a plurality of pin holes, which are formed so as to pass through a pin-up rope of a pin jig, are formed in a zigzag direction in a 90 占 direction to endure a buckling load A stopper for temporarily stopping the height of the lifting rod is provided in a plunger manner on the fixed support base which is inserted inwardly so as to raise and lower the lifting rod while a plunger is installed on the other side of the fixed support, A pin jig for a ship block support is proposed in which a penetration hole for confirming a position is formed and the plunger of the stopper is easily fitted to the pin hole of the other side while confirming the position of the pin hole by the sight hole, .

Fig. 1 shows a ship block support according to the prior art.

A plurality of pin holes 3 are formed at regular intervals in a fixed support 1 which is vertically installed on a base of a workplace and a pin pin 3 is fitted with a pin 4 , The pin holes (3) are alternately formed in the zigzag direction along the 90 占 direction, and the pin holes (3) A through hole 5 for confirming the pin hole 3 is formed in the upper part of the front face. A through hole is formed through the fixing support 1 in the 90 ° direction of the through hole 5, Is inserted.

This conventional technique also uses a heavy equipment for moving the block support or tilts the support, and there is a danger of a conduction accident. In order to adjust the height of the block support, a screw system is frequently used. However, And it does not solve the difficult problem of fine adjustment.
