Description

The present invention relates to a reversing facility plate body Ru reverses the front and back of the plate, in particular, the inversion of curved plate-shaped body reversal Suitable plate body, such as steel sheet used in the outer shell of the vessel Regarding equipment.

  Steel plates used in the construction of vessels such as container ships and merchant ships are divided into plate-like bodies with a side length of several meters to several tens of meters, formed into a desired shape, and then bonded together by welding. There are many. In particular, a steel plate used for the outer shell of a ship is linearly heated and bent using a gas burner or a high-frequency heating device. In such a bending process, it is not possible to form a desired shape simply by heating the surface of the steel sheet. Therefore, it is necessary to heat the steel sheet from the back side, and it is necessary to invert the steel sheet. In addition, when some processing must be performed on the front and back of a plate-like body such as a steel plate, it is necessary to invert the plate-like body. However, steel plates are generally heavy, and it is dangerous for the operator to turn the crane while operating the crane, so there is a problem that multiple people are required to work carefully and the efficiency is poor. . Then, what was described in patent document 1 and patent document 2 is proposed as an apparatus which reverses a plate-shaped object, for example.

  The reversing device described in Patent Document 1 suspends and conveys a disk-shaped disk, places it on the rotating part of the reversing member, operates the hydraulic cylinder of the disk pressing mechanism, and clamps the disk at the pressing part. This is a device for reversing the disk by rotating the rotating part. In the reversing device described in Patent Document 2, the swing arm is moved down so that the beam and the arm are positioned below the transfer device, and the plate-shaped steel plate is transferred directly above the swing arm. The electromagnet is energized while swinging to the bottom, and the steel plate is attracted and held from the lower surface side by the magnetic force, and the swing arm is further lifted to lift the steel plate upward of the transfer device and rotate the beam 180 degrees to reverse the front and back of the steel plate The swing arm is lowered and the steel plate is placed on the transport device to demagnetize the electromagnet.
