Definitions

  • the present invention relates to an hydraulically-driven oscillating mechanism and particularly, though not exclusively, is concerned with a mechanism for traversing from side-to-side in an oscillatory angular manner the nozzle of a fire-fighting monitor or the like liquid-projecting device. It is known to provide fire-fighting monitors with mechanisms of this kind so that the monitor can be set up with its nozzle automatically swinging through a predermined arc to play a jet of water or foam from side-to-side over a desired target area.
  • One such mechanism comprises a Pelton-wheel driven by water taken from the main supply to the monitor, the wheel being connected through a speed-reducing gearbox to a crank which is linked at its other end to the structure bearing the monitor nozzle, so that the rotation of the Pelton wheel is transmitted by the crank into oscillatory angular motion of the nozzle.
  • the present invention seeks to provide an hydraulically-driven mechanism for producing oscillatory angular motion of a monitor nozzle or other device and which in a preferred embodiment may employ a primary transmission similar to that described above, but furthermore where the sector of the horizon (or other plane in which the angular motion is produced) in which the device operates can be readily adjusted without altering the spatial disposition of the mechanism as a whole.
  • the invention resides in a mechanism comprising an hydraulically-driven motor and a mechanical transmission for connecting the motor to a driving member whereby operation of the motor produces oscillatory angular motion of said driving member which is characterised by clutch means through which such oscillatory angular motion of the driving member is transferred to a driven member,the clutch means being selectively operable to disengage the driven member from the driving member to permit rotation of the driven member independently of the driving member, and adapted to permit re-engagement of the driven member with the driving member in different relative angular positions thereof.
  • the driven member can be connected e.g to the nozzle of a fire-fighting monitor to oscillate that nozzle from side-to-side through a predetermined arc and thereby play fire extinguishant over a corresponding area. If it is then desired to change the direction of the nozzle to cover an area not within its existing arc the clutch means can be operated to disengage the drive from the motor to the nozzle and permit the nozzle-and said driven member to be rotated into a new position, whereupon re-engaging the drive will recommence ocillation of the nozzle through a new arc angularly displaced from the previous arc.
  • the clutch means comprises a polygonal socket member and a polygonal spigot member, one such member comprising or being in driving connection with said driving member and the other comprising or being in driving connection with said driven member, these members normally being biased into engagement to permit angular drive transmission from one to the other but being selectively disengageable to permit relative rotation between them.
  • the two clutch members can be engaged in a plurality of discrete relative angular positions determined by the faces of the polygonal spigot and socket, so as to set the driven member to oscillate the nozzle or other device in a corresponding number of angularly displaced sectors.
  • a fire-fighting monitor 1 which in the illustrated embodiment is of the spherical head type and which in particular may be constructed as described in our published United Kingdom patent application No 2071527A.
  • this monitor comprises a head 2 which carries a nozzle via an outlet fitting 3 and which is borne in a housing 4 for pivotal movement about a horizontal axis so as to adjust the angular elevation or depression of the nozzle. In the illustrated embodiment this adjustment is conducted manually for which purpose a handle-bar 5 is provided.
  • the assembly of the head 2 and housing 4 is also rotatable as a whole about a vertical axis so as to permit the nozzle to be traversed angularly from side-to-side, to this end the assembly being fast on the upper end of a hollow vertical axle 6 which is borne rotatably in a fixed body 7 and which also serves to lead water to the head 2 in use of the monitor.
  • a mechanism 8 ( Figures 1 to 4) which is arranged automatically to oscillate the axle 6 through a predetermined angle (and with it the head 2 and the nozzle carried thereby), so as to play repeatedly from side-to-side the jet of water or foam which is discharged by the monitor. This mechanism will now be described.
  • a main water supply pipe 9 Beneath the monitor is a main water supply pipe 9, fed from below and arranged to deliver water into the rotatable axle 6.
  • a branch flow is also taken from this pipe and delivered via a shut-off valve 10, non-return valve 11, filter 12 and throttle valve 13 to a Pelton-wheel motor (turbine) 14, of which the jet nozzle 15 and runner 16 are seen in Figure 3.
  • the Pelton-wheel is driven to rotate at high speed by the supplied water, and its rotation is transmitted by a speed-reducing gearbox 17 to a drive wheel 18.
  • a crank arm 19 is pinned eccentrically to the wheel 18 and the arm 19 is pinned at its other end to a shorter drive arm 20 fast with a shaft 21.
  • the shaft 21 constitutes the input member of a clutch 22 mounted behind the monitor 1 and, as will be seen, its axis is parallel to that of the axle 6. It will also be appreciated that the effect of the linkage between the wheel 18 and the shaft 21 is to impart to the shaft an oscillatory angular motion as the wheel 18 rotates, the amplitude of which is determined by the throw of'the arm 19 and the effective length of the arm 20.
  • the oscillatory motion of the shaft 21 is transmitted through the clutch to a drive gear 23 coaxial with the shaft (but not keyed or otherwise secured in driving relationship to the shaft except through the clutch parts as described below), and this gear is in mesh with a ring gear 24 keyed to the axle 6 so that as the gear 23 oscillates so also does the axle 6.
  • the upper end 21A of the shaft 21 is of square cross-section and engages in a complementary hole in a member 25 which also defines a downwardly-facing polygonal (eg hexagonal) socket 26.
  • this socket member is biased downwardly by a spring 27 so as to engage over a complementary spigot 28 integral with the drive gear 23, and in this condition the member 25 serves to transmit the oscillatory motion of the shaft 21 to the gear 23.
  • the biasing spring 27 for the socket member 25 is, as shown, compressed between the member 25 and a ring member 29 held in the end of a fixed cylindrical casing 30.
  • the socket member 25 can, however, be slid upwardly on the square end of the shaft 21 so as to disengage from the spigot 28.
  • a stem 31 which is located relative to the socket member 25 by means of a ring 32 screwed to the top of the socket member and engaging over a flange 31A at the lower end of the stem, so as to permit relative rotary movement between the member 25 and stem 31.
  • a cover 33 in the form of a control knob and which is axially and rotatably slidable on the casing 30.
  • the stem 31 also carries a cross-pin 34 which, when the clutch is engaged, lies within a complementary slot 35 in the member 29 (ie as shown in full line in Figure 6).
  • a cross-pin 34 which, when the clutch is engaged, lies within a complementary slot 35 in the member 29 (ie as shown in full line in Figure 6).
  • the gear 23 can be rotated relative to, and independently of, the shaft 21 and the rest of the preceding transmission.
  • the apparatus has been set up to oscillate the monitor nozzle through a certain horizontal sector and .it is subsequently desired to change the sector within which the nozzle operates it is not necessary to shift the entire apparatus to point the nozzle in the appropriate new direction; rather the clutch 22 is operated to disengage the drive from the shaft 21 to the gear 23, and the monitor head 2 and casing 3 can then be pivoted by manipulation of the handle-bar 5 to place the nozzle into the new sector in which it is desired to operate, in so doing the gear 23 being rotated by the gear 24 fast with the axle 6 into a new direction; rather the clutch 22 is operated to angular position relative to the shaft 21. Re-engaging the clutch thereafter reestablishes the drive between the shaft 21 and gear 23, so that the nozzle is driven to oscillate through the same angle as before, but in a
  • the nozzle can be made to operate in any one of a number of discrete sectors of the horizon, the number of sectors being determined by the number of possible relative angular positions of engagement between the spigot 28 and socket 25, or in other words between the gear 23 and shaft 21.
  • the clutch 22 can be' operated to disengage the gear 23 from the shaft 21 whenever it is desired to override or shut down the automatic oscillating mechanism and traverse the monitor nozzle manually or by some alternative control system.
  • the amplitude of the automatic oscillation of the nozzle is open to variation as well as its sectoral disposition.
  • the drive wheel 18 is provided with a plurality of holes 38 (in the illustrated embodiment, five) as seen in Figure 4, to receive the pinned connection of the crank arm 19. These holes are at different radii from the axis of rotation of wheel 18 so that variation in the throw of the arm 19, and thereby in the amplitude of oscillation, can be achieved by disconnecting the arm from one hole 38 and reconnecting it to another.
  • a range of from 60° to 100° of arc in 10 0 increments is provided for the nozzle oscillation by this means.
  • the frequency of oscillation of the nozzle can also be varied by variation of the speed of the Pelton-wheel, and this is achieved by controlling the water pressure to the Pelton-wheel by means of the throttle valve 13.
  • the pressure of water tapped off to the Pelton-wheel is controlled between 3.5 and 14 bar to give an oscillatory frequency range of from 3 to 15 cycles per minute.
  • the water supplied to the wheel drains from the motor through an outlet.39 ( Figure 1).
  • the maximum water consumption of the motor is only in the region of 55 litres/minute which is a negligible proportion of the total flow to the monitor.
  • a further inlet to the Pelton-wheel water circuit is provided by a T-piece 40 located between the non-return valve 11 and filter 12.
  • This inlet is normally blanked off but can be connected to a suitable water supply when it is desired to test the Pelton-wheel and the rest of the oscillatory mechanism without having to discharge water from the monitor itself, ie without having to supply the pipe 9.
