DESCRIPTION:
BRIEF SUMMARY
The invention relates to an installation for storing and transporting elongated objects, particularly rods and pipes.
The storage of such elongated objects causes certain problems in connection with the arrangement thereof in the storage places and particularly in connection with their removal therefrom, especially if the rods or pipes have different lengths, diameters and possibly even material qualities. There is also the problem of transporting them from the storage place to the further processing location. Admittedly the conventional fixed storage place permits extensive subdivision, but with the exception of the top compartment they only permit loading and unloading from one end face. This means that the pipes or rods generally delivered in groups or bundles have to be virtually individually inserted into the associated storage chassis, which is time-consuming. Removal can also only take place in the same way. As a result a space must be left following onto the end face of such chassis whose length must at least correspond to that of the elongated objects to be stacked. In turn this leads to space problems. In the case of such chassis it is also virtually impossible to avoid the final objects placed therein, i.e. those at the top being the first to be removed for further use, whereas the objects below them are often left stored for a long time, which is also disadvantageous from the sales standpoint.
The object of the invention is to obviate these disadvantages and provide an installation for the storage of elongated objects which, if required, permits loading and unloading from above or from the end face and which can also be easily moved in both the loaded and unloaded states. This is intended to facilitate changes and modifications within the organisation. If needed the installation should also facilitate transportation between the storage place and the processing point.
According to the invention such an installation is characterized by the features of claim 1.
During transportation it may be necessary to lift the elongated objects by means of a lifting device, usually a crane. However, it is a well-known fact that in a bundle of elongated objects containing both longer and shorter objects, it is difficult to establish the centre of gravity point at which the bundle is to be raised. There is also the danger that on raising the whole bundle may be brought into an undesired or even dangerous inclined position. All that can be done to avoid this is to move the lifting device backwards and forwards several times until the centre of gravity is found and the attached bundle remains relatively horizontal. However, it is very time-consuming to determine the correct suspension point.
A preferred embodiment of the invention which obviates these disadvantages is characterized by the features of claim 6.
An exemplified embodiment of the invention is represented in the drawings, wherein show:
FIG. 1 a stack of individual frames viewed from the front, a roller support and a lifting device.
FIG. 2 a plan view of a single frame.
FIG. 3 a perspective view of an insertion container.
FIG. 4 a roller support, also in perspective view.
FIG. 4a a roller insert for a frame.
FIG. 4b a variant of both FIG. 4 and FIG. 4a.
FIG. 5 a lifting device and part of a frame in side view.
FIG. 6 details of the cooperation between lifting device and frame.
FIG. 7 a modified embodiment of the lifting device.
In FIG. 1 several frames 1 to 4 are stacked on top of one another, whilst a further frame 5 is shown raised from the stack. As shown there can be certain differences in the frames, particularly in their height. The essential point is that they are stackable and consequently all have the same width. According to FIGS. 1 and 2 each frame comprises two longitudinal beams 11, 12 and a plurality of cross-bars 13 or 13a-e which interconnect the beams. The number of cross-bars in a function of the frame length. On considering the left-hand beam in FIG. 1, each beam 11, 12 approximately has the shape of the letter Z or the FIG. 2 with and
