DEVICE FOR CONVEYING FLUID MATERIALS
The pre~ent inventlon relates to a device ~or conveying fluid materials as de~ined in claim l.
German patent publication DE 2,055,2~8 describes a concrete conveyor comprising a set of tele-scopic booms and a hose through which concrete i6 con-veyed. Moreover, the device is provided with a windingdrum on which the hose i5 wound and from which it is unwound as required.
A problem with the previously known devices is that the telescopic boom structure is general}y rela-tively heavy. Consequently, this 6ets rather. narrow limits on the extension leng~h o~ the boom structure.
Especially the weight o~ the outermost partis of the telescopic structure have a considerable e~ect on the extension length.
Another p~oblem with previously known devices is that the ~lexible ho~e ueed ln connection wlth the telesGopic boom structure has a rough interior surface retarding the motion o~ the material conveyed through the hose. Therefore, the pump used for moving the ma-terial is subject to a hard strain, naturally dependiny on the material being pumped.
A further problem with previously known de-vices is that pro~ection and cooling arran~emets must be provided to protect the end of the hose attached to the~ out~mos~ mem~er of the telescopic boom structure 1f the device i8- used e.g. for rire-flgnting: purposes.
Ths object of the pre6ent in~ention is to e}iminate or at least to reduce the above-mentioned drawbacks.
~he device of the invention is characterized by what i5 pre~ented in clalm 1.
The device o~ the invention comprisa5 a ~rame provided with a tel~scopic boom structure and a hose ~or conveying a fluid material, the hose being fitted ~ -- .

inside the tele~copic boom structure. According to the invention, the outermost membar of the telegcopic boom struature consists o~ a rigid tube ~lidably fitted inside the pracedln~ member o~ ~aid ~tructure, the end of the hose inside this member b~ing connected to the feed end o~ 6aid rigid tube.
In an embodiment of the device, the member preceding the outermost one in the telesooplc boom structurè is provlded with internal sliding rings placed at a distance from each other, said rings supporting the outermost member as it slides through them.
In an embodlment of the device, the outermost member o~ the telescopic boom structure is provided with a no2zle placed at the delivery end of the member.
In an embodiment of the device, the nozzle is provided with a valve, e.g. a magnetic valve, permit-. I ~. .~ ~

In an embodlment of the device, a Plexible tube i6 provlded at the delivery end o~ the outermost member of the telescopic boom structure.
In an embodiment of the device, the outermost member o~ the tele6copic boom structure consi~s of a metal pipe.
The invention has the advantage that the outer-most member of the telescopic boom structure i5 of a simple construction.
~other advantaye ofithe invention i6 that the outermos~ mem~e~ o~ the te~leficD~ic boom ~ruc~ure i9 relatively light and yet- 6turdy.
A furtèr adyantage of the invention is that the outermost member of the-telescopic boom structure can b~ easily connected to the rest of the boom struc-ture.
Moreover, the invention has ~he advantage that the extQnsion length o~ the boom strUctUre can be in-creased as compared to previously known telescopic boom structures without increasing the stress moment.

Furthermore, the ir.vention allows a more efficlent conveyance of fluid materials through the device. Tha outermost member of the telescopic boom structure is a tube with a smooth interior surface, presenting a low frictional opposition to the flow of the material. Regarding the material flow .in the critical part of the boom structure, a con~lderable improvement is thu~ achieved a6 compared to earlier ~oulutions. Thls is of great import~nce e.g. in the lo case of concrete as the material conveyed.
In addition, the device of the invention can be used in fire-~ighting without protecting or cooling the outermost member of the telescopic boom structure.
The end of this member can be brought close to ~he flre.
Be~ides, the invention permits simple mounting of a nozzle and/or valve on the outermo~ member of th~
telescopic boom ~tructure.
A further adv~ntage of th~ lnv~ntion i~ that the end of the telescopic boom struc~ure can be easily directed and the material will ~low in a clearly defined direction. This is important e.g. in fire-fighting.
In the following, the invention is described in detail by referring to the appended drawings, in which: .

- The telescopic boom structure 3 cansists of two or more elongated telescopic members 3a, 3b, 3c, 3d movable relative to each other and mounted at least partially inside each other. The outermost member 3a of the tele5copic boom structure 3 consists of a rigid tube slidably mounted in5ide the preceding telescopic member 3b. The end 4a of the hose 4 inside the tele~coplc boom structure 3 is connected to the feed end of the ri~ld tube 3a.
The telescop~c boom structure 3 is prov1ded with at least one hydraulic motor 7, by means. of which the telescopic members of 3a, 3b, 3c and the hose can 1~ be moved.
The hose ~ is ~itted in5ide the telescopic boom 6tructure 3. Thus it is well protected against external stres~e5 and impacts. The hub 6 o~ the winding drum 5 is attached to the ~rame 2 of the dovic~ 1. At least part o~ the ho5e 4 i~ wound on the reel 4c when the device is in the re5~ po5ition. From the reel 4c.
an extenslon 4b of the hose 4 goes through the hub 6 into the ~rame 2. The hose extension 4b leads out from in6ide the frame, e.g. into a pump unit 8. Thi6 can be provided with a 5uitable addi~ional hose 4d through which the material in question is pumped into the device 1.

The nozzle i6 preferably provided with a valve 14, e.g. a magnetic valve, which can be adjusted via remote control.
Alternatively, instead of a nozzle 10, the delivery end 3a" of the outermost member 3a o~ the telescopic boom structure 3 can be provided with a ~lexible tube 15 with a ~upport 16. By mean~ o~ the flexible tube 15, the mat~rial pumped through th~ d~via~
can easily be directed manually ko khe target. In thi~
case, the telescopic boom ~tructure 3 need not be accurately directed at the target, because the tube lS
can be bent and adjusted as far as its length permits.
This is an impoxtant feature e.g. when the devlce l is used for conveying concrete.

Thus, if the device 1 ig mounted on a vehicle, the control unit may be placed ln the cabin of the vehicl~.
~ n principle, the device o~ the invention works as follows. For example, when a suitable ~luid lo material is to be conveyed ~rom a tran6port container into a ~torage container using the device of the invention, mounted in conjunction with the storage container, the device i5 operated as follows. The end 3a" o~ the outermost member 3a tor the end of the flexib~e tube 15 in ~ig. 2). of the tele~copic boom structure i8 brought into aontaat wikh the tran~port contain~r by operating the hydraulia a~llnder 12 to lift the boom structure 3 to a ~u~ficient h~ight and the hydraulic motors 7 to extend the telesaopic members 3a, 3b, 3c to a suf~icient distance ~rom the frame 2.
Slmultaneously, the required length of the hose 4 is automatically unwound from the reel 4c of the winding drum 5 by means of the hydraulic motor 9 in synchroni6m with the telescoping action of the boom 6tructure 3.
After the end 3a" has been connected to the transport containerr the pump 8 i6 started and the mnterial in the transpor~ container i6 conveyd through ths hose :~ : into: the: storag8~ containe . A~t~r- the tr~n~por~
~:con~a-iner has^been~smptied, thie end 3a" is-d~tached f~om the trans~ort container, whereupon the tele~copic `members 3a, 3b, 3c are driven into one another by the ~: hydraulic motors 7 and the boom ~tructure i8 lowered to a suitable rest posltion. If neces5ary, the device 1 can be turned about the verlcal ax~ B o~ the ~rame 2 to a dasired po~ition.
The device o~ the invention can be used to handle many kinds of ~luid materials, e.g. liquids, woso/1o588 PCI/FI90/OOfl53 2 0 ~
gases, solid, granular or powdered mat~rial6 and variou~
mixtures thereof. Moreover, it is to be noted that these materials or mixtures thereof can be conveyed in a manner known in itself, e.g. using underpressure or overpressure or trans~er air, or the material can be pumped through the hose 4 in a desired direction using the pump 8.
A remote-controlled nozzle 10 can be employed e.g. when the devlce of the invention is used in ~ire-fighting to convey ~luid materials 6uch as water or fire foam.
The device of the invention can also be applied in the conveyance of materials li~e concrete, coarae~
aggregate, gravel and sand. A signi~icant advantage with the device is that the outermost member 3a of the boom structure can be relatively ldng in relatlon to the total length o~ the structure, ~o tha~ A large ranye of adjustment and radiu~ o~ oporatlon, e.g. 4 - 20 m, o~ the boom etructure i~ achi~ved.
In the ~oregoing, the invention has been described by referring to only one of its preferred embodiments, but it is obvious that the invention can be implemented in various ways within the scope of the idea of the invention as defined in the following claims.
