Definitions

  • the present invention relates to a winding device and unwinding for flexible hose, in particular for a hose to supply an aircraft with fuel.
  • the aircraft are supplied with fuel at by means of reinforced pipes, the diameters and lengths of which are relatively large.
  • a hose must be wound up when not in use, and a winding and unwinding device is used for this purpose, comprising a reel which is rotated by means of a engine.
  • a reel known in this application includes a hub constituted by a part machined in the mass and rims constituted by assembly of metallic elements, these rims comprising branches radial welded to the periphery of the hub.
  • the hub has an axial fuel supply port and a radial fuel outlet, to which the hose is connected by through a bent pipe. It also includes two bearings with balls by which it can rotate on a tree.
  • the radial branches are connected two by two transversely, from one rim to the other, at their base, these connections also used for mounting a spiral sheet which constitutes the bearing surface of the first turn of the pipe.
  • a toothed crown is attached to the base of the radial arms of one of the rims, to allow the drive in rotation of the reel via a chain engaged on this crown and on the motor pinion.
  • This device has several drawbacks.
  • the drive system is cumbersome, since the large diameter of the ring gear, which is imposed by the fixing of this crown on the base of the radial branches, implies an offset important lateral of the motor compared to the reel.
  • the catchment areas the chain with the crown or the pinion of the engine is therefore not placed out of reach of the personnel, which obliges the installation of protective casings without any danger being excluded.
  • the present invention aims to remedy all of these disadvantages.
  • the device which it relates comprises, in a manner known in itself, a reel formed of a hub which is constituted by a piece of foundry and two rims connected to this hub via radial branches, the hub being integral with a ring gear, coaxial to itself, used for the rotational drive of the reel.
  • the toothed crown is therefore no longer secured to the branches radial, as in the prior art, but is integral with the hub, which does not require perfectly rigid and solid connections between the radial arms and the hub to support the transmitted torque by the engine. Therefore, the radial branches of at least one of the rims can be removably mounted on the hub, allowing easy to reach, even after mounting the device on its structure support, the pipe connecting the pipe to the hub and the sheet spiral reel, to adapt the position of this pipe and this sheet in the desired winding direction.
  • said pipe is removably mounted on the hub and the means mounting of this pipe on the hub are provided to allow placing the pipe in two opposite positions corresponding to one or the other of the two possible directions of hose rewinding.
  • the spiral sheet is as for it removably mounted on the branches of the rims, and branches include means for placing said sheet in two inverse positions, these positions also corresponding to either of the two possible directions of winding of the pipe.
  • the manufacture of the reel is very notably facilitated by the possibility of separately producing the hubs and rims and then assemble hubs and rims as required.
  • the ring gear can come in direct contact with the pinion of the engine, which not only significantly reduces the overall dimensions of the assembly but above all allows to position the gear zone outside staff reach.
  • the toothed crown is arranged in the periphery of the outer annular part of a bearing, this part outer annular being integral with the hub while the annular part inside of the bearing is integral with the support structure of the device.
  • This unique bearing the outer annular part of which is securely mounted on the hub, eliminates costly machining to be made at the hub bore according to the technique anterior.
  • said inner annular part is integral a plate intended to be fixed to the support structure of the device, this plate also comprising the motor.
  • the plate, the motor, the bearing and the hub thus form a assembly which can be mounted individually on this support structure, and if necessary independently of the rims.
  • the plate can also include means for connecting the inlet pipe of the fluid.
  • the hub includes, on its periphery, legs from the foundry with itself, for mounting the branches of the rim closest to said crown toothed, and the other rim includes a circular part, on which are fixed its branches, this circular part being intended to be mounted on the hub.
  • the circular part gives a rigid structure to this second rim, more particularly likely to be disassembled.
  • Figure 1 shows a tank truck 1 intended for fueling aircraft.
  • truck 1 includes a hose 2 which is wound when not in use on the reel 3 of a device 4 for winding and unwinding this pipe 2.
  • the device 4 comprises, in addition to this reel 3, a motor 5 for driving the reel 3 in rotation and a plate 6 on which the reel 3 and the motor 5 are fitted.
  • This plate 6 is itself mounted on a frame 7 which forms the support structure of the device 4, this frame having been shown diagrammatically on the Figure 1, for clarity, by a simple plate.
  • the reel 3 is formed by a hub 10 and two rims 11, and has a bent pipe 12 for connecting the pipe 2 to this hub 10 as well as a spiral sheet 13 which forms the bearing surface of the first turn of hose 2.
  • the hub 10 is constituted by a casting part. As shown in particular in Figure 4, it has a central portion 10a which delimits a bent fuel flow duct 15, opening out through axial and radial orifices respectively for inlet and outlet of the fuel, and a peripheral part 10b, which is delimited by two faces axial ends 16, of annular shape, and which includes lugs 17 projecting radially outwards, with holes 18.
  • the rims 11 are formed by assembling rigid elements and include radial branches 20.
  • the branches 20 of the rim 11 located on the side of the plate 6 are removably connected to the legs 17 via bolts.
  • the branches 20 of the other rim 11 are connected to a circular part 21 pierced with holes, and tapped holes corresponding are arranged in the hub 10 at the face 16 located opposite, to allow removable mounting of this rim 11 on this hub 10 by means of screws.
  • the hub 10 On the side of the plate 6, the hub 10 has a bearing 25 ball 26, mounted coaxially to it. This assembly is carried out by through screws 27 which are engaged through the annular part outer 25a of this bearing 25 and in tapped holes correspondents that includes the hub 10 at the face end 16 located opposite.
  • the outer annular part 25a of this bearing has a toothing 30 arranged in its periphery, suitable for engaging with the pinion 31 of motor 5, this pinion 31 and the shaft of motor 5 being engaged through an appropriate opening which is arranged in the plate 6.
  • the inner annular part 25b of the bearing 25 is itself bolted to plate 6, as shown in figure 4. This bolting also allows the mounting of a flange 32, to which the flange 33 of the fuel supply line 34, and a ring 35 forming the seat of O-rings 36, the assembly constituting a seal turning which ensures the tight connection of said pipe 34 to hub 10.
  • the radial hole of the hub 10 is delimited by a square base 37 in the corners of which are tapped holes, and the pipe 12 comprises a square flange 38 pierced with corresponding holes.
  • the arrangement of these holes allows the mounting of the pipe 12 on the hub 10 in two reverse positions, shown respectively in lines solid and broken lines in Figure 2, corresponding to the two possible direction of winding of hose 2 on reel 3.
  • the branches 20 are pierced with pairs of holes 40 located at look at each other from one rim 11 to another. These holes 40 are intended for mounting the sheet 13 and are arranged so as to allow the mounting of this sheet 13 in two opposite positions, shown in solid lines and in broken lines respectively in FIG. 2. These two positions also correspond to the two winding directions pipe 2 possible on the reel 3.
  • This assembly is carried out, as well as this appears in Figure 4, by means of transverse tubes 41 integral of the internal face of the sheet 13, which come opposite the pairs of holes 40, these tubes 41 and holes 40 being able to receive studs 42 threaded to their ends, on which clamping nuts 43 can be screwed.
  • the invention thus provides a device for winding and unwinding for flexible hose, in particular for a hose supply of an aircraft with fuel, making it possible to remedy the abovementioned drawbacks of homologous devices of the technique anterior.
  • the hub can have an axial length such that a winding of the pipe is possible not according to a spiral but according to one or more helicoid; the hub can incorporate either a mechanical braking mechanism, pneumatic or hydraulic, with manual control or automated.
