Definitions

  • the invention relates to a device for moving work platforms, which are provided for pivoting the work platforms in vertical planes boom, which are mounted on a support member about vertical axes horizontally pivotable, and which are pivoted into a basic position.
  • Such devices may be used, for example, for the inspection or maintenance of the interior walls of a tank space.
  • 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 probably represents the upper limit.
  • WO 2006/119520 a device of the type defined above is disclosed. This is already largely ready for use, as soon as the support member is inserted with the arms to the lower end position in the tank space. 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.
  • the arms In the basic position, the arms must be very close to each other, so that they can be pushed through the standardized inlet opening of the tank space.
  • the cantilevers in the basic position are offset radially outward with respect to their vertical axes of rotation.
  • the pivoting of a boom about its vertical axis would be hampered by the adjacent boom.
  • the operating position of the device is therefore achieved by displacing the vertical axes of the arms radially outward by about 100 mm by means of a four-bar mechanism. This requires a relatively high design effort.
  • the object of the invention is to avoid the high design effort in the prior art.
  • the stated object is achieved in that the boom in the basic position are offset relative to the associated vertical pivot axes in the direction of a closed contour, which surrounds the support member together with the arms.
  • Protection is also desired for use of the device according to the invention for inspecting or processing the inner walls of a tank space, with the proviso that the basic position allows the in and out of the boom together with the support member through an upper opening of the tank space.
  • the device according to the invention can also be used in oil platforms for inspection or processing of individual areas. Such maintenance is necessary for oil platforms for corrosion protection.
  • Fig. 1 shows schematically the different phases of introduction
  • Fig. 2 to 5 show in four phases in each case in a cross section and a diagram, the transition from the basic position to the operating position in an inventive device.
  • the invention is not limited to embodiments in which the support member 3 together with the arms 2 by the defined by the dome 13 insertion is introduced together with an enveloping tube 1.
  • the supporting part could also be fastened to a mast projecting, for example, into the interior of a tank space or to struts which carry the deck 11.
  • boom 2 in a basic position as shown in Fig. 2, to arrange around the support member 3 around that they by merely pivoting about the vertical axes 8 in the operating position of FIG. 3 to 5 can be brought.
  • the articulated arms 5 are pivoted to the investors 2 zoom. This measure results in a very small cross-section, so that in the optional use of a tube 1, the entire assembly of support member 3, boom 2 and articulated arms 5 can be easily pushed through the tube 1.

Abstract

L'invention concerne un dispositif destiné au déplacement de plateformes de travail (6) et comportant des bras (2) qui font pivoter les plateformes de travail (6) sur des plans verticaux, ces bras étant logés orientables à l'horizontale autour d'axes verticaux sur un élément support (3) et pouvant être rentrés en position de base. En position de base, les bras (2) sont déplacés relativement aux axes de pivotement (8) verticaux associés, dans la direction d'une ligne fermée (11) qui entoure l'élément support (3) et les bras (2).
