Abstract

The present invention relates to a detachable pin jig, and more particularly, to increase the utilization of the yard by being able to attach and detach the pin jig to secure the ship block.

Conventionally, by installing a pin jig fixed in a shipyard, such as a ship assembly block in a yard, the pin jig is fixed to the grid plate to protrude by a welding method. There was a bulge that protruded and could not operate the yard efficiently. In addition, when the pin jig was installed, welding work for fixing the pin jig was performed in a narrow work space, which caused a lot of difficulties in the work.

The present invention has been made to solve the above problems, the subject of the present invention is to install a circular fixed base on the top of each intersection of the grid-like plate installed on the yard surface, the lower end of the pin jig mounted on the top of the fixed base The part is fixed to the circular fastening plate by welding, the embodiment of this is inserted into the pin jig of the subject innovation in the upper part of the fixed pedestal installed in the yard when the ship block, etc. fastening of the fixing base and the pin jig The pin jig is fixed by combining the plate, and if there are no blocks to be loaded in the yard, the pin jig is removed from the fixing base to remove obstacles protruding from the yard so that the yard can be used for other purposes.

Description

Removable Pin Jig {A Removable Pin Jig}

The present invention relates to a structure in which a pin jig, which is a device for placing heavy items, such as a ship assembly block, can be detached and attached to a fixed yard of a yard.

Conventionally, the pin jig is installed on the upper surface of each intersection of the grid plate of the yard by welding to protrude on the ground, so that even when the block is not placed, the pin zigzag cannot be used for other purposes. There is a problem, in order to solve this problem, the pin jig that can be removed and attached.

The present invention relates to a pin jig that can be attached and detached, and more particularly, it is characterized by increasing the utilization of the yard by allowing the pin jig used for placing the ship assembly block to the yard.

Conventionally, when a ship assembly block is placed in a yard in a shipyard, the block is placed on the top of a pin jig fixed to the yard. Even if not, the pin jig protrudes on the ground, which makes it difficult to use the yard for other purposes. Due to the welding work, there were many difficulties in the work, which lowered the productivity and the risk of safety accident during work.

The present invention has been made to solve the above problems, the subject matter of the

On the upper surface of each intersection of the grid plate 3, which is installed in a grid using a steel beam, a plurality of circular fixed pedestals 2 are fixedly attached by welding, and are coupled with the fixed pedestals 4. At the center of the lower end of the pin jig (1) is characterized in that the structure consisting of a fixed structure by welding a circular fastening plate (2) formed a through-hole formed in the size of the fixing base (4) can be inserted It is to be done.

The present invention relates to a detachable pin jig, and when a ship assembly block is placed in a yard, a pin jig is installed on an upper part of a fixed pedestal installed in the yard, and a heavy object such as a block does not need to be placed in the yard. In this case, by removing the pin jig from the fixed base, the yard, which is a large space, can be efficiently used for other purposes, which is a very practical effect.

The present invention relates to a detachable pin jig, described in detail based on the drawings as follows.

On the upper surface of each intersection of the grid plate 3, which is installed in a grid using a steel beam in a yard formed in the shipyard, a circular fixed pedestal 4 having a diameter of 30 cm and a thickness of 3 cm is welded. In the center of the lower end of the pin jig 1 which is fixedly attached to the fixing bracket 4, and has a through hole 2a of a size into which the fixing bracket 4 can be inserted. The fastening plate 2 is welded and fixedly mounted.

The embodiment of the present invention inserts the pin jig 1 of the present invention into the fixing pedestal 4 fixedly installed on the grid plate when the heavy object such as a ship block is placed thereon. Since the fixing pedestal 4 and the fastening plate 2 of the pin jig 1 are combined, the pin jig 1 is fixed to the yard without a separate fastening method, and the pin jig above does not have a block to be loaded in the yard. By simply releasing (1) from the fixing pedestal (4), there is no protruding obstacle in the yard so that the yard can be used for other purposes.
