Definitions

  • the invention relates to a device for bringing work platforms to the inner walls of a tank space, wherein for pivoting the platforms are provided boom, which are held by an insertable through an upper opening of the tank space mast.
  • a conventional tanker is divided into tank rooms with dimensions of 20 mx 20 mx 20 m. These have a standardized upper filler opening of 1250 x 750 mm, which represents the only access to the tank room apart from a manhole for operators.
  • movable working stations are provided in three directions, from which the inner walls can be inspected, treated with sandblasting, phosphorized and painted. Even to minimize the downtime of the ship in the yard, but also for technical reasons, the processing of the entire interior should be completed in the shortest possible time. In this sense, it is advisable to arrange more than one work basket on the central mast, with the use of four baskets in practice is probably the upper limit.
  • the device is already largely ready for use, as soon as the boom is pushed through the pipe down. It is only necessary to connect the working baskets, which have been introduced in advance into the tank space, and at most these articulated arms, which connect with the arms, to the outriggers.
  • a particular advantage of the invention is that the formation of the mast as a tube, the available clear width of the upper opening of the tank space static maximum utilization and at the same time provides a space for the arrangement of supply lines.
  • the bottom of the tank room may only be moderately loaded, it can absorb horizontal forces. This is advantageously utilized by a further mast is connected to the support member, for which at the bottom of the tank space a backup against horizontal displacement is provided.
  • this supported on the ground further mast is also designed as a tube. This makes it possible to accommodate supply lines in the initial state in a collapsed form in this tube. These supply lines then extend after the extension of the boom from the support member of the boom to the recess provided in the deck.
  • FIG. 1 shows schematically the different phases of introduction and construction of a device according to the invention in a tank space
  • Fig. 2 is a schematic representation of a second embodiment (with lower
  • FIG. 3 shows, in section, the arrangement of a jib immediately after extension
  • FIG. 4 shows the device according to FIG. 3 after the radial swiveling out of the jib
  • FIG. 5 shows a side view corresponding to FIG. 3
  • FIG. 6 shows a section to FIG the line AA.
  • the basic idea of the invention is to stow the arms of a processing device in a folded state in a tube 1.
  • This cladding initially serves as protection against damage to the difficult mechanics and designed to the strength limit steel structure in rough shipyard operation. It allows horizontal storage of the system on the ship until the tube 1 is brought with the stowed boom from the ship's crane 15 by means of a steel cable 7 to the site.
  • the tube 1 together with the cantilevers mounted therein lowered by the opening formed by a dome 13 of a tank space and connected to the dome 13 after complete lowering by means of an automatic lock 16.
  • Tube 1 Since that Tube 1 is now fixed to the dome 13, go on further lowering of the rope 7 fixed to a support member 3 boom 2 down (second and third image in Fig. 1). Subsequently, the still to be described in detail locking of the support member 3 at the lower end of the tube 1 and finally the connection of the boom 2 with prepared articulated arms 5 and 6 platforms.
  • a lateral deflection of the entire device under the load exerted by the platforms is prevented in the embodiment of FIG. 2 by a fuse 10, in which a likewise formed as a tube further mast 4 engages. This is based on the bottom 12 predominantly from the side, so that the weight of the assembly does not have to be absorbed by the bottom 12, but is collected by the deck 11 supporting struts.
  • FIG. 5 is a side view of the central part 3 lowered down through the tube 1. It can clearly be seen that in this position corresponding to FIG. 4, the pivot drives 17 for the extension arms 2 can move them without mutual interference.
  • Fig. 6 is additionally illustrated by the example of two arms 2, as the pivoting of the boom about horizontal axes 9 can be done. Above all, however, one sees how the other two arms, which are shown in the position according to FIG. 3, fit into the tube 1 and how exactly on the other hand the tube 1 bears against the inside of the dome 13. Above the support member 3 is in the pipe 1 sufficient space for supply lines. These can be arranged during the retraction and extension of the support member 3 in the support member downwardly continuing pipe 4, which is fixedly connected to the support member 3. Incidentally, this tube 4 serves to firmly anchor the entire device to the bottom 12 of the tank space.
