Definitions

  • This invention relates to a lighting tower.
  • Such existing lighting towers have a purpose of providing a high level of uniform lighting for the television of sports and conventionally there are four to six such towers around a particular arena each tower being constructed so that the tower in all conditions of wind and ground disturbance will support in a very stable manner lighting of very high magnitude.
  • each lamp typically there are 100 or more individual lamps for each tower each lamp of which being capable of illuminating with some 2000 watts of electrical power to achieve lighting levels of over 1500 lux.
  • each lighting tower invariably provides for a human passageway up through the supporting column and a platform behind each of the respective rows of the lamps so that each of the lamps can be safely and individually orientated or aimed and of course be replaced or serviced.
  • the problem then is how to provide lighting for such facilities in a way that will provide sufficient lighting from an appropriate height to provide appropriate incident angles for the light while being sensitive to the demands of local residents in respect to the appearance of the towers and al the time achieving these requirements at an acceptable cost.
  • This invention solves the problem of reluctant community acceptance of large lighting structures constructed in aesthetically sensitive environments whilst at the same time enabling easy and safe maintenance of the lighting system.
  • This invention therefore has for its object the reduction of the problems generally expressed above and assisting in aesthetics and ease of maintenance or at the least provides a useful alternative for the public.
  • a lighting tower comprising a retractable pole arrangement, a head frame supported by the pole arrangement at an upper end of the pole arrangement, an array of lights supported by the head frame and means to effect a raising and lowering of the pole arrangement.
  • the pole arrangement supporting the head frame is comprised of at least two separate sections one of which is arranged to telescope from the other when the pole arrangement is being raised and to nest one within the other when the pole arrangement is retracted.
  • the head frame is adjustable in position so that when the pole is in a retracted position, the head frame has its major planar orientation aligned substantially horizontal and when the pole is in a raised or erected position, the head frame is aligned in a light projecting orientation.
  • the head frame can be raised merely minutes before being used in lighting an arena and can be lowered minutes after completion of lighting of the event.
  • the visual impact is temporary and would only occur during those times of the night when illumination is required. This means that they will conventionally not be raised during any substantive daylight period of any day and only toward night or during an evening so that they will be less visible.
  • FIG 1 is a side elevation of a lighting tower according to a first embodiment shown in the partially raised position
  • FIG 2 is a side elevation of the lighting tower as in fig 1 when in a retracted position
  • FIG 3 is a cross-sectional view along the lines AA in FIG 1 ,
  • FIG 4 is a cross-sectional view along the lines BB in FIG 1
  • FIG 5 is a cross-sectional view along the lines CC in FIG 1 ,
  • FIG 6 is an elevation of the head frame showing from a front view the supporting head frame structure and lights supported on this with some of them removed to show the support arrangement and the frame support structure,
  • FIG 7 is a cross-sectional view along the lines DD in FIG 1 ,
  • FIG 8 is the same view as in FIG 1 except that it is shown fully
  • FIG 9 is the same view as in FIG 1 showing the retracted and elevated positions of the head frame
  • FIG 10 is a perspective view of lighting tower constructed in accord with a second embodiment and illustrated in the fully raised position with the head frame in a light transmitting orientation
  • FIG 11 is a perspective view of the detail of the cavity shown in FIG 10 with the covers lowered
  • FIG 12 is a side elevation in cross section of the top of the shaft and the cavity with the pole arrangements almost fully retracted and showing the location of the head frame when in a stored position with the pole arrangement fully retracted,
  • FIG 13 is a perspective part cut away of the shaft insulation with the pole assembly shown schematically to illustrate the arrangement of the cable by which the upper pole section is caused to be raised at twice the speed of the lower pole section,
  • FIG 14 is again a schematic view in cross section illustrating more features of the down the shaft assembly according to the second embodiment
  • FIG 15 is an enlarged view in cross section showing the motor drive assembly according to the second embodiment together with details of the interlocking openable beams by which the position of the lower pole section can be locked in position as appropriate but particularly when the pole arrangement is in its fully raised position,
  • FIG 16 is a view along the lines DD in FIG 15,
  • FIG 17 is a schematic view being a view taken as a cross section through the lowered upper and lower pole sections and viewing these from above,
  • FIG 18 is a cross sectional view through the shaft near to the bottom of the shaft showing more specifically the location of the bottom pullys and drainage and vent shafts, and
  • Fig 19 is a perspective view of the arrangement for supporting the lights in accord with the second embodiment.
  • the pole arrangement 1 is comprised of two pole sections namely an upper pole section 2 and a lower pole section 3 each of the pole sections being square in cross-sectional shape and being of such dimensions that the upper pole section 2 will retract into a nesting position within the lower pole section 3 and the lower pole section 3 will retract fully into a ground shaft 4.
  • a head frame 5 which is pivotally supported at a lower end at 6 for rotation about a substantially horizontal axis the degree of rotation being controlled by hydraulic ram 7 a lower end of which is pivotally secured to the upper pole section 2 at 8 and an upper end of which is pivotally secured at 9 to the head frame 5.
  • the head frame 5 comprises a number of frame members supported in crossing relationship and shown generally at 10. These define in a general way a plane reference to the alignment of which can be useful The effective alignment for a light transmission position of the head frame has been chosen at 20 degrees to the vertical of the plane of the head frame for this embodiment.
  • Each of the individual lights shown typically at 11 are supported in such a way that they can be individually positioned from their back by azimuth and other controls which can be selected and then preset.
  • a feature of this arrangement is that these settings can be achieved while the head frame with the attached lamps is in the position as shown in FIG 2 so th with the doors 12 open access can thereby be achieved when the head fram is within the cavity either close to or beneath the ground.
  • This shaft is constructed in this first embodiment using a rotating cutting head attached to conventional boring equipment producing a shaft which is then lined with a steel liner within which is located an inner liner of cross-sectional shape to match the shape of the pole arrangement 1 and more particularly to allow the lower pole section 3 to retract into the inner liner 14 which is then embedded into the outer liner 13 with concrete therebetween shown at 15.
  • the depth of the shaft may be in the order of 45 meters some care needs to be taken to ensure that the shaft is aligned very closely to vertical because thi will then provide the alignment for the supported pole arrangement.
  • an assembly including electric motor 17, an hydraulic pump and hydraulic swash plate motor, a gear train 18 and two pinions 19 which engage racks 20 and 21 secured to the steel liner of the shaft 4.
  • the assembly is supported by a cradle supporting the motor and the two pinions engaging each of two racks one to each side of the shaft the cradle being supported by a pivot connection to the supported pole section whereby engaging pressures are equally distributed between the pinions with the respective racks.
  • the lifting speed is chosen to be very slow so that there is a low inertial load upon start up. To assist this further it is arranged that the full speed is reached only after small acceleration this being typically 6.0025 meters/sec/sec over ten seconds to reach the maximum lifting speed of 0.025 meters /second. On calculations this keeps the apparent load supported by the pinions when in the lifting mode in the typical instance to approximately 65 tons.
  • the lifting procedures are controlled by a control program from a computer which controls the speed of the drive from the variable speed hydraulic motor
  • the respective racks 20 and 21 are secured to extend vertically up the inner sides of the inner liner 14 of the shaft.
  • the racks need to be very accurately aligned and secured to the inner liner with sufficient strength to support these very high loads.
  • the use of the load distribution technique in which the drive motor assembly is supported by a cradle which is in effect a gymbal assists very much in reducing undue high load on one only of the pinions and its associated rack and has resulted in very significant savings in the costs of machining the racks to an accuracy needed to otherwise keep the loads to an economic limit.
  • the motive force for raising the upper pole section 2 is achieved by adding a cable and pulley system.
  • a continuous cable anchored with respect to the shaft at 28 this location being simply chosen to allow for easy access for adjustment of the length of the cable from time to time.
  • the cable passes downwardly around a pulley 25 fixed to the bottom of the shaft and then the cable passes upwardly inside the lower pole section 3 to the top of this where it passes around a pulley then down and around pulley 27 returning again to the oppositely located position around the top of the lower pole section 3 to the other anchor point 29.
  • this pulley and cable arrangement means that as the lower pole section 3 is raised the upper pole section will be forced to rise at a speed which is twice that of the lower pole section 3. Further when the upper pole section 2 is at its fully raised position the cable will act to support this in this elevated position.
  • the control of the swash plate hydraulic motor is operated to restrain the acceleration typically to the 0.0025 meters /sec/sec and a maximum speed of 0.025 meters / second.
  • Power is supplied by a series * of busbars 30(a) which are located to extend fully along the shaft and there area set of electrical contacts fixed at the base of the lower pole section 3 and sliding against the fixed conductor bars of the shaft.
  • a second set of vertically mounted electrical conductor busbars 30(b) are fixed to the inside face of the lower pole section and extend its full length and then power is transferred to the upper pole section 3 by a second set of sliding electrical contacts fixed to the base of the pole section.
  • a further feature of this invention is that the alignment arrangement is achieved by selection of an aiming alignment in the first instance and then by use of computer calculations each of the aiming positions of each lamp can be predicted and preset when the head frame is either in its cavity or close to the ground or on the ground so that when these are erected there is reasonable certainty that the lighting distribution will be uniform.
  • This of course means that the tower structure does not have to provide for support for individuals in an elevated position on the tower so that safety factors do not have to be incorporated for this situation.
  • the construction which implicity will be much more slender than previous fixed lighting towers does not have to take account of deflections caused by extremes of winds because it can be anticipated that in the event of severe weather that is very high winds, the lighting tower can simply be retracted or they will not be needed in that in high winds ball games may no longer be sensibly played.
  • the tower has to of course be designed so that it will not fracture in such high winds.
  • a reduction in deflections caused by resonant wind loading can be achieved by active damping.
  • Such a facility can be included in this embodiment attached to the head frame and can provide damping over a selected frequency range corresponding to the fundamental or the first two natural frequencies of the tower. This damping is effective to reduce resonant deflection especially due to vortex shedding from the head frame which reduces fatigue deterioration of the structure and also reduces shadow movement during operation of the lights during normal usage.
  • the tuned liquid damper is toroidal in shape which provides that it works omnidirectionally.
  • a series of baffles inside the damper creates a high level of turbulent diffusion of the fluid inside the body due to form drag.
  • the dampers are filled approximately to a mid height with a glycol mixture and then tuning to damp specific frequencies in specific directions can be achieved by varying the amount of fluid.
  • One further advantage is that it is anticipated that advertising can be included on the sides of the pole sections firstly because they present planar faces and secondly because they are only temporarily in view in circumstances which may not otherwise be acceptable for the support of advertising on a permanent basis in such a place.
  • a hydraulic disc brake 32 which is functionally located between the output of the hydraulic motor and the reduction gearbox so that in the event of absence of hydraulic fluid driving pressure, the disc brake will engage.
  • openable beams 33 are located at the lowermost end of the lower pole section 3 which are arranged so that in the event of any failure such as total loss of hydraulic power, the beams are positioned so that they will engage and interlock with the sides of the shaft casing thereby acting to impede calamitous falling of the structure.
  • the pole arrangement 34 includes an upper pole section 35 and a lower pole section 36.
  • the upper pole section 35 has attached at an upper end thereof a head frame
  • the general alignment of the frame members making up the head frame can be considered to generally define a plane and the chosen angle of this to the vertical is 20° which is found to be inappropriate light transmitting orientation which is of some value.
  • the relative orientation of the head frame 37 is controlled by hydraulic ram 39 which is driven by an electric motor driving a hydraulic pump which in turn drives an hydraulic motor in the close vacinity of the hydraulic ram 39 but which is not specifically shown.
  • an active damper 40 Located behind the head frame and arranged to provide dynamic damping is an active damper 40.
  • the pole arrangement 34 is adapted to be retracted into a shaft 41 and there is a cavity 42 which is able to be closed by covers 43 and 44 which are arranged so that they will allow the head frame and the upper pole section to initially project above a ground level and thereafter close having secondary covers 45 and 46 which will remain open to allow the lower pole section 36 to pass therethrough and to slide therealong.
  • the covers 43 and 44 are arranged so that when the pole arrangement 34 is fully retracted and the head frame is within the cavity 42, the covers can close across and provide for safe and reasonable egress across the top of the covers for any conventional purpose including vehicular traffic.
  • the shaft 41 is now seen in greater detail and there are particularly shown a vent conduit 51 and a water drainage sump conduit 52 whereby any water that will gather from time to time in the bottom of the shaft can be detected and withdrawn and according to a operating procedure, water is introduced on a regular basis both to ensure that pump means which are not specifically shown and the level detection means are in operating order and are kept under regular supervision, and that by introducing air on a regular basis into the bottom of the shaft, this will cause circulation which in turn will at least reduce humidity for long term reduction of corrosion of the parts within a shaft.
  • the two uppermost anchor points for cable 53 are shown at 54 and 55.
  • the cable goes down to pulley 55 which is permanently secured to the bottom of the shaft and is therefore fixed in relation to the shaft 41.
  • the cable then rises to pulley 56 which is attached to the top of the lower pole section 36 and it then goes down to pulley 57 which is attached to the bottom of the upper pole section 35.
  • the cable is then fed across to pulley 58 which is also attached to the bottom of the upper pole section 35 from whence it rises to pulley 59 which is attached to the top of the lower pole section 36.
  • the cable then goes down to 60 which is again attached to the bottom of the shaft 41 and then returns to an anchor point at 61.
  • the motor assembly 70 which includes an electric motor 71 , an electrically activatable brake mechanism 72 a hydraulic pump 73 and a hydraulic squash plate motor 74 which drives through a gear assembly 75 to drive pinions one of which is shown at 76.
  • An oil reservoir for the hydraulic pump and associated variable speed motor is shown at 77.
  • the motor drive assembly 70 is all supported together so as to be rotatable about shaft 78 so that pinions which are better shown in Figure 15, can share the supporting load between them.
  • the motor assembly 70 has more of the gear arrangement shown in Figure 15 which includes gear element 82 driving gear element 83 which is on the same shaft as gear 84 which directly drives pinion 81 and indirectly through further element 85 pinion 76.
  • the lower pole section 36 is supported at its end on shelf 86.
  • a framing assembly shown at 93 which again provides support for pads 94 and 95 which engage corner element 96 which is secured to the main body parts of the square shape of the upper pole section 36.
  • the pads are comprised of a reinforced plastics material which is in each case the pads are comprised of a thermoplastic polymeric material which is sold in Australia and uniquely identified by the registered Trade Mark "Vesconite".
  • Figure 18 shows the bottom of the shaft and a cross sectional view of the surrounding concrete which has been shaped in this case to match the square shape of the pole arrangement elements.
  • Figure 19 illustrates in greater detail the arrangement for support of the lamps and in particular shows the supporting arrangement whereby each is supported by a bracket which firstly supports for accurate indexing of the orientation of the lamp about axis 100 which is measurable through gauge 101 and for orientation of about an approximate vertical axis by reference to gauge 102.
  • control mechanisms including a torque control in respect of the electric motor is also included so as to limit to a safe extent the amount of acceleration and deceleration and accordingly inertial forces.
