Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for inserting a longitudinal material, which constitutes the framework of a ship's block or the like, into a slit in a transformer material.

The framework of the ship block consists of a transformer material with slits formed at a predetermined pitch, and a longitudinal material that is inserted into the slits of the transformer material, and the two parts are integrally welded at their intersections. It is assembled as a structural member.

By the way, in the past, longitudinal materials were placed and welded on skin plates connected to a predetermined size, and then the lance materials were lifted one by one using a crane, and transformer materials were attached to the longitudinal materials. A construction method in which the longitudinal material is inserted sequentially from the end side so that the slit faces, the side of the longitudinal material is joined to one side edge of the transformer material, and the color plate is pressed against the slit part to weld the mutual joints at multiple locations. was adopted.

However, this method requires a large number of color plates and has the drawback of increasing the amount of welding work.

In order to eliminate this drawback, firstly, 1. lance materials are regularly arranged upright at predetermined intervals to hold them firmly, and then 4. lance materials are inserted from one side of the lance materials for temporary use. We proposed a so-called framework construction method in which the completed framework is exposed by welding, and then placed on a skin plate and attached to the skin. There are space and equipment constraints.

In addition, if a method of inserting each longitudinal material into the transformer material individually requires a large number of charging devices, if a method of inserting multiple longitudinal materials at the same time is adopted, the insertion is smooth. This causes inconveniences such as it is extremely difficult to get the person to do so.

The present invention has been made for the purpose of providing a further improved construction method that takes advantage of the advantages of the conventional construction method and compensates for its shortcomings, and will be explained below based on drawings showing embodiments.

In other words, Fig. 1 is an explanatory diagram showing the process of inserting longitudinal material into transformer material in sections. First, the skin plate, which has been welded to a predetermined size, is placed in place while taking into consideration the arrangement of the overhead equipment, etc. when carrying out the block. Then, the transformer material 2 is positioned and arranged on the skin plate 1 while preventing it from falling by using a fall-prevention horse stand or a tru wire.

At this point, the sagin plate is moved to a position where the longitudinal material can be placed, and this is fixed using a pick-up tool or the like.

Next, prepare for work by setting the temporary support 3 that supports approximately the middle part of each longitudinal material, and further setting the insertion base plate 4 that supports the rear end of the longitudinal material and has the function of pushing it. complete.

In the above-mentioned work, it goes without saying that the temporary holder 3 is made seven times in accordance with the pitch of the slits in which the transformer material 2 is provided.

Next, as shown in FIG. The rear end is placed on the insertion base plate 4 to keep it horizontal, and the positioning member 6 erected at the front end of the insertion base plate 4 and the temporary holder 3 maintain parallelism.

The skin plate 1 and the insertion base plate 4 described above are mounted on the roller conveyor 7, and the skin plate 1 is fixed at a proper position and the insertion base plate 4 is placed in a movable state.

In addition, the temporary support 3 has the function of supporting each longitudinal material 5 and adjusting the position according to the arrangement interval of the longitudinal materials 5, and when the insertion base plate 4 passes during the insertion operation to be described later. It has a structure that allows it to rotate and lie down in the insertion direction so as not to prevent its operation.

Further, an insertion member 8 is mounted on the insertion base plate 4 and acts to contact the rear end of the longitudinal member 5 to directly push it. The elongated hole 9 provided in the protruding chain 10 is pushed by a power transmitter 11 that transmits the movement of the chain 10.

By the way, after completing the arrangement of the longitudinal members 5 as shown in FIG. 1a, the chains 10 are respectively driven to advance the power transmitters 11 sequentially by a large amount starting from one side, and the insert members 8 are moved forward as shown in FIG. 1b.
Then, as shown in FIG. 3, by displacing the longitudinal material 5 in an oblique manner, the longitudinal material 5 is sequentially pushed forward starting from the one at one end, and as shown in FIG. After inserting, the tips of all the longitudinal members 5 are aligned diagonally in a straight line, and then the chains 10 are equally driven to start the full-scale insertion operation.

At this time, as the insertion base plate 4 comes into contact with the temporary holder 3, the temporary holder 3 is rotated and laid down, so that the insertion base plate 4 can pass freely.

Then, the insertion base plate 4 is stopped in contact with the edge of the skin plate 1, and when the state shown in FIG. 1C is reached, each power transmitter 1
The speed of each chain 10 is adjusted so that the positions of the chains 1 and 1 are aligned horizontally, and the insertion material 8 is moved parallel to the edge of the insertion base plate 4 as shown by the imaginary line in FIG. In this case, all the longitudinal members 5 are inserted equally into the transformer member 2 as shown in FIG. 1d.

In the insertion procedure described above, first the insertion member 8 is positioned obliquely, and the longitudinal member 5 is aligned with the front end surface of this insertion member 8.
It is also possible to adopt a method of arranging materials.

Furthermore, the present invention aims to achieve this by arranging the tips of the longitudinal members obliquely from those at one side end and inserting them into the dowel lance members sequentially starting from the one at the preceding one end. The equipment for this purpose is not specified.

After the insertion is completed, the chain 10 may be driven in the opposite direction. At this time, the insertion base plate 4 can be moved back by bringing the power transmitter 11 into contact with the rear edge of the elongated hole 9. As a means, it is also possible to move the insert member 8 by a small amount and reposition the power transmitter 11 to its front end side to perform a backward movement.

In the present invention, on the side of the transformer material disposed and held on the skin plate, the longitudinal material is arranged and supported horizontally and parallelly in correspondence with each of the slits L, and one end of the longitudinal material is supported. In order to advance from the beginning, the tips of all the longitudinal materials are aligned in a straight line with the needle, and the insertion is started sequentially from the leading longitudinal material. Since the insertion is performed sequentially starting from the end, it is possible for a small number of workers to accurately and smoothly adjust the tip position of each longitudinal material immediately before insertion, thereby reducing the load on the insertion device. It is possible to reduce the number of problems caused by insertion, and also to solve the problems that occur in the past at the time of insertion.

Moreover, since the insertion device itself can be made into a single unit with a relatively simple structure, the space required for this operation can be significantly reduced, and the number of workers for managing insertion can be reduced, making it possible to achieve smooth and efficient operation. insertion is achieved.
