Definitions

• the invention relates to a spooling machine comprising two side frames spaced at a horizontal distance by a telescopic spacer beam, each frame having a pintle on supports for bearing a drum for cable pipe or hose, the telescopic spacer beam comprising at least one outer tube and at least one inner tube, which are slidably and telescopically one inside the other and a locking device positioned between the outer tube and the inner tube for locking the outer and inner tube in adjustable position.
• the invention relates to floor reeling devices, i.e. a pay-off devices or a take-up devices widely used for example in manufacturing electrical wires and cables, i.e. in various fields of cable manufacturing industry.
• Reeling devices or spooling machines consist typically of two side frames spaced at a horizontal distance by a telescopic spacer beam. Each frame has a pintle on vertically movable supports. The supports support and bear the drum onto which a cable, pipe or hose is paid off or taken up.
• a typical known structure uses frame distance adjustment achieved by means of a telescopic spacer structure in which a bar is made of a cylindrical rod sliding in a bushing similar to hydraulic cylinders.
• the precision fit of rod and bushing requires expensive precision manufacturing which means that the constructions used in the prior art rise the costs of for example cable manufacturing process.
• the object of the invention is to obtain an arrangement by which the disadvantages of the prior art can be eliminated. This is achieved with the present invention.
• the present invention is characterized in that the locking device comprises a split part of the inner tube extending over a part of the length of the inner tube and dividing the inner tube into sections, and a force element for creating a swelling force on the split part of the inner tube to press the sections against the inner surface of the outer tube.
• An advantage of the invention is its low manufacturing costs and therefore the use of the invention is very advantageous as a whole, i.e. the invention offers an economical way to obtain adjustable spacing function in connection with a reeling or a spooling machine.
• Figure 1 shows an example of a spooling machine known in the field
• Figure 2 shows a front view of one embodiment of the arrangement of the invention
• Figure 3 shows a top view of the embodiment of Figure 2
• Figure 4 shows a section along the line A - A shown in Figure 2
• Figure 5 is a detail of Figure 4 shown in a larger scale.
• Figure 1 shows a typical spooling machine of the prior art.
• the spooling machine shown comprises two side frames 1 spaced at a horizontal distance by a telescopic spacer beam 2.
• the telescopic spacer beam 2 is in the prior art technique made of a cylindrical rod sliding in a bushing similar to hydraulic cylinders as described earlier.
• the construction shown is also provided with an appropriate locking device positioned between the outer tube and the inner tube for locking the outer and inner tube in adjustable position.
• the construction shown has the disadvantages of the prior art described earlier.
• the invention offers an economical way to obtain the adjustable spacing function, i.e. an economical way to eliminate the expensive construction of the adjustable spacer beam used in the prior art.
• Figures 2 - 5 show one embodiment of the present invention, i.e. one embodiment of the arrangement for a telescopic spacer beam of the invention.
• the spacer beam 2 comprise two square tube sections, i.e. an outer tube 3 and an inner tube 4.
• Said square tubes are made of commercial steel tubing and said tubes form a telescopic arrangement which can be seen clearly from Figures 2 and 3.
• the outer tube 3 is a solid tube with for example a suitable flange 5 for attachment to the side frame 1 of a reeling device.
• the inner tube is also provided with an appropriate flange for attachment to the side frame as shown in the Figures.
• the inner tube 4 has a smaller section than the outer tube 3 such that the inner tube 4 can be fitted inside the outer tube 3 with some clearance to form a telescopic structure as shown in Figures 2 and 3.
• the locking device comprises a split part 6 of the inner tube 4. Said split part 6 extends over a part of the length of the inner tube as shown in Figure 3. Said split part 6 divides the inner tube 4 into sections 7, 8.
• the locking device comprises further a force element 9 for creating a swelling force on the split part 6 of the inner tube 4 to press the sections 7, 8 against the inner surface of the outer tube 3.
• the inner tube 4 has been split in a certain way.
• the inner tube 4 has been split in the vertical axis into two sections 7, 8. This however not the only possibility but also three, four or even more split sections can be used.
• FIG. 2 - 5 uses square tubes as the outer tube 3 and the inner tube 4.
• the invention is not however restricted into square tubes but other tube shapes can be used too, as an example a hexagonal form can be used etc.
• the force element 9 comprises an inflatable bag element or an inflatable hose element.
• the invention is however not restricted a certain type of force element, i.e. it is also possible to use for example hydraulic or electrical cylinder or a wedge element as a force element 9.
• the embodiment shown comprises advantageously also flat bars 10 fixed on the inside of the outer tube 3 to provide a vertical guiding of the inner tube 4 in the outer tube 3.
• the guide rolls 1 1 are preferably spring-loaded guide rolls.
• the embodiment may further comprise bars 12 extending over at least a part of the inner tube 4. Said bars 12 are fitted in the inside corners of the outer tube 3. Said bars 12 are preferably half square bars but it should be noted that appropriate other forms may also be used.
• the inflatable or pressurizing bag element 9 When the inflatable or pressurizing bag element 9 is inflated, it exercises a swelling force on the inner tube 4 which will swell with its split part such that the sections 7, 8 are pressed against the bars 12 fitted in the inside corners of the outer tube 3, and thereby fixing or locking the inner tube 4 respective to the outer tube 3.
• the inflatable bag element 9 may be inflated through an appropriate element for example through a pipe 13.
• the inflatable or pressurizing element 9 When the inflatable or pressurizing element 9 is deflated, the swelling force disappears and the inner tube 4 is released with respect to the outer tube 3 so that telescopic movement of the inner tube and the outer tube is enabled.
• the invention has been described above with an embodiment using two interacting tubes.
• the invention is not restricted to that but it is quite possible in the invention to use also for example three or even more interacting tubes.
