Definitions

  • the invention relates to a chute extension unit which has a transport container and a flexible storage chute which is shortened compared to its starting length by a plurality of transverse folds while narrowing its clear cross section, which cooperates with a guide tube which is accommodated in the narrowed chute cross section and supports the transverse folds, as well as one end of the storage flute is provided with a connecting flange for a pulling device which strips the other end of a flute tour to be extended over the guide tube, and at the opposite tube end has a spreading flange which slides on the inside of the flute and which seals the guide tube against the flute jacket.
  • extension units make it possible to dispense with adapters for the extension of lute tours, the end of which, for example, must best follow a tunnel or a section of the underground operation at a constant distance from the face. They enable a higher degree of rationalization in the construction of such special ventilation systems because they avoid the stoppage of the lute tour associated with the fitting and removal of adapters and the associated interruptions in the ventilation of the tunneling and the related dangers extend to periods that are longer and longer thus correspond to a longer tunneling length. With the extension unit according to the invention, you can work in such a way that the entire pre-built length of the tour is only made up of these extension units.
  • the invention is based on a ventilation extension unit in which such dangers are eliminated by using a transport container.
  • the storage duct is folded with the aim of accommodating the largest possible duct length in the smallest possible storage space.
  • a fold is particularly suitable for this purpose, in which polygons are produced from the Lutte in the fold planes and are offset from one another in neighboring planes.
  • the folded storage duct delivered in the transport container is prepared for installation by placing it on the guide tube.
  • This guide tube can be attached to the tapered end of one in the Luttentour attach the funnel to the other end of which the expansion flange is attached. In this way, the duct can be folded to save space and protected from damage by the transport container when it is folded, and can be prepared and used one after the other for installation.
  • the object of the invention is to simplify the transport containers and to design them in such a way that the stored tubes remain protected against damage until they are deployed in the tube tour.
  • the transport container consists of a tube housing, which in turn is composed of a cladding tube covering the folded storage tube and formed by a tube, the guide tube also realized with a tube, and its flanges, the connecting flange being the annular
  • the bottom of the housing forms and the expansion flange closes off on the inside an annular gap which is delimited from the outside by a cladding tube end, through which the storage end of the storage duct to be connected to the Luttentour exits.
  • the empty weight of the transport container is saved first. This is because it consists of the light air duct material, ie mostly of a fabric constructed from synthetic threads, which is coated on the inside and / or outside with a thermoplastic. Due to the flexibility of such pipes, the empty transport container can also be reduced to a small transport volume. In this way, the conditions are created for folding the storage duct in the manufacturing plant and inserting it into the respective transport container. Then the underground container only needs to be brought into the starting position for storing the air. Then the connection end of the storage flute, which can be easily removed through the annular gap, can be connected to the flute tour, and the unloading can be carried out in the usual way. The storage flue remains with its folded Length in the transport container until its inner end is pulled off over the guide tube. As a result, the cladding tube protects it from damage.
  • the invention has the advantage that it reduces the Statn losses to a small and inevitable extent, namely to the cases in which the transport container and the storage lute contained in it are damaged or otherwise lost.
  • the invention also has the advantage that it uses low-quality transport containers which also have a low transport weight and a small transport volume.
  • the pipes of the pipe housing are designed as spiral pipes, which are welded at their ends facing the housing base to a film forming the connecting flange.
  • Film can also be understood to mean the ventilation material described above.
  • This embodiment of the invention has the advantage that the parts can be easily welded to one another using the tried and tested method of plastics technology and all parts are flexible. On the other hand, the necessary stiffness in the cladding tube and in the guide tube can be easily achieved by the incorporated spirals.
  • the cladding tube is provided on the outside with suspension means.
  • suspension means can be previously known eyelets or brackets with which the transport container can be suspended from one or more trolleys of a monorail monorail when the storage channel is pulled out.
  • the duct extension unit according to the invention can in turn be designed such that the guide tube between the tube end and the expansion flange has a funnel consisting of a plastic film or the duct material.
  • This funnel which is known per se, serves, among other things. to avoid eddies during the transition of the weather flow from the Luttentour into the narrowed cross section of the Speicherlutte.
  • a blowing lute tour for example, which is generally designated by 3 and is only shown with its front end 4.
  • the lute tour consists of flexible lutes, each of which has a ring 5 made of round steel at its ends, which is incorporated into the lute jacket.
  • the pipes On the upper side, the pipes have a bar 6 with eyelets (not shown) which are spaced apart from one another and through which suspension cables 7 and 7 'can be pulled, that is, connected, with which the lute is suspended in a manner not shown in detail from the ridge 2 of the route 1.
  • trolleys 9 and 10 On the roof there is also a cantilevered rail 8 of a monorail overhead conveyor, of which, however, only two trolleys 9 and 10 designed as bottom flange sliders are shown schematically.
  • the trolleys 9 and 10 carry the lute extension unit, generally designated 11, which is explained in more detail below.
  • its basic structure consists of a transport container 12, which is designed as an upper housing, and a flexible storage duct 15, shortened by a plurality of transverse folds 14 by narrowing its clear cross section, which is shown schematically in the transport unit 11 Structure according to the Lutten, which are already installed in Luttentour 3.
  • the storage flute 15 has at both ends a round steel ring 16 or 16 'surrounded by the flute material, with which it can be coupled to the round steel ring 5 of the end 4 with the flute tour 3 via a band 17, as shown in FIG.
  • This band 17 in turn has a fixed ring 18 and 19 on its inside, and these two rings include rings 5 and 16 when the band is closed. In this way, a tensile coupling is created.
  • the tube housing 12 of the transport unit consists, on the one hand, of an enveloping tube 20 consisting of a spiral tube corresponding film 23 are covered, the. Foil is welded with its edges to the outside of the Luttenmantels 21.
  • the tube housing 12 consists of a guide tube 24 which is also realized with a spiral flute, the structure of which corresponds to the structure of the cladding tube 21, which differs from the guide tube only in its comparatively larger diameter.
  • the two tubes 20 and 24 are arranged concentrically and provided with a connecting flange forming the housing base 25 at one of their ends.
  • this connecting flange is an annular disk made of pipe material, that is to say in turn flexible and welded to the ends of the concentric tubes 20, 24 by means of an inner and an outer fillet seam 26 and 27, respectively.
  • An annular space 28 is thereby formed, in which the folded duct can be accommodated.
  • the cladding tube 20 is somewhat longer than the guide tube 24, but forms with its other end shown at 29 the outer boundary of an annular gap 30 which is delimited on the inside by an expansion flange generally designated 31 (FIG. 2).
  • This expansion flange in turn consists of an annular disk 32 made of Lutten material and on the other hand from a coupling ring 33, which corresponds to the coupling rings described so far, but has a slightly smaller diameter than this.
  • the storage duct 15 is folded and inserted into the tube housing 12 forming the transport container. This can be done mechanically and therefore, despite the flexibility of the transport container 12, does not pose any difficulties. Since the diameter of the coupling ring 33 is smaller than the diameter of the coupling ring 16, the connection end of the stored can Place the tube completely in the transport container, leaving only the annular gap 30 free. In this state, the air extension unit 11 can be transported safely in any way.
  • the transport unit with the stored duct is suspended on the two trolleys 9 and 10 of the monorail overhead conveyor with the help of eyelets 34, 35 which are fastened to the cladding tube 20.
  • the coupling ring 36 attached to the connecting flange 25 the entire transport unit 11 is coupled with a pipe, not shown, which is attached to a tunneling machine and e.g. belongs to a nozzle from which the ventilation air exits, which is blown in the Luttentour 3.
  • the end of the storage chute carrying the ring 16 is removed through the annular gap 30 by pulling out part of the storage chute.
  • the coupling ring 33 which is covered by the material of the guide tube, slides on the inner surface 37 of the storage duct and clamps it onto the end cross section in the duct tour 3. This takes place against a corresponding resistance with which the lute sleeves slide on one another and has the result that their plastic coatings seal against one another.
  • the result of this is that the inside of the transport unit 11 in the transport unit is relieved of the overpressure of the lumen tour 3 and only the guide tube is loaded with the overpressure of the weather current.
  • the annular disk 32 When pulling out the storage tube end associated with the coupling ring 26, the annular disk 32 is also deformed axially and forms a funnel jacket, as can be seen from FIGS. 1 and 2.
  • This funnel shape improves the flow conditions in the area of the expansion flange of the transport unit 11, so that there are fewer vortex and flow resistances.
  • such resistances are also relatively insignificant, because the storage unit 11 is axially short due to the tight folding of the storage duct and therefore the weather flow only has to pass a short pipe length until it emerges.
  • the advance machine also moves in the direction of the arrow 38 in FIG. 2 and takes the storage unit 11 along with it via the flange 25 and its ring 36.
  • the storage flute is pulled out of the annular space 28 until its inner end provided with a coupling ring 16 'finally passes through the flange 31 and the ring 33, whereupon a new storage unit 11 is installed.
  • the tubes of the storage unit are stiffened with external spirals. This results in smooth inner walls, which are expedient both for fluidic reasons and for reasons of easier storage of the duct.
