Definitions

  • the presented invention refers to arrangement for mainly vertical movement of lighting installations in premises of great height to the ceiling as factory-, athletics- and exhibition halls and facilities, which often are equipped with lighting equipment that are disposed rather close to the ceiling so as to permit an unrestricted utilisation of the entire hall volume. That gives rise to the problem that the intensity of illumination as time passes is gradually decreased due to that the lighting gets dirty and also due to that some of the lighting get inoperative and must be changed or repaired.
  • the invention primarily is thought of as a lift for lighting equipment it is evident that it also can be applied for other uses. E.g. for units with sensors of different kinds, which for their proper function can claim uninterrupted galvanic connection and a precise position when lifted to its highest position or for raising and lowering of inner-ceilings of arbitrary shapes, with or without lighting installed. Even other alternatives for transport or movement for to the arrangement applied objects are possible within the the invention, as shifting and rotary-motion in one or more directions or just one of these alternatives.
  • a known way to avoid over-sized and energy-wasting lighting installations and to add comfort and safety to the maintenance crew is that the armatures are arranged vertically movable, so that they from their normally very high operational position may be lowered down to a position in convenient working height for service and maintenance.
  • the installation can be based on hand-driven and inconvenient winches or motor-driven expensive system for every separate armature or smaller group of armatures, the latter alternative is e.g. shown in the Swedish patent 8207360-2 and in encl. illustration.
  • the presented invention has also the aim to offer considerable freedom to arrange a lighting installation or similar formed in accordance to the facilities actual needs through the possibility to arrange a great number of armatures in one hoist-arrangement also with large measures in length or width or both.
  • lighting arrangements where the light from an intensive light-source is distributed by means of tubeformed lightguides, lightpipes, mirrors or other reflector systems in order to create a uniform lighting over large areas.
  • a need that can be foreseen, in regard to the limited heights in tunnels, is not in the first hand to move the lighting-installations up and down for accessibility, rather then a horizontal moving for simultaneous service and cleaning of two or more parallel continuous lighting-installations over traffic lanes.
  • An application where combined movement, sideways and with partial rotation can become actual is for lighting of traffic lanes in road-tunnels, with each lane having its own continuous arrangement of light-pipes.
  • Service and maintenance must here be possible to carry out, fast and with a minimum of disturbance of the traffic, and closing of lanes must be limited so that the traffic always can flow at least in one lane.
  • the lighting tubes be so arranged that they can be partially rotated the light from the arrangement still can be directed towards the open lanes where the decrease of lighting thus can be kept to a minimum.
  • Another example of utilisation of the invention is horizontal movement of long lighting installations could be in green-houses for uniform distribution of light covering large areas and with for the crop adjusted intensity.
  • a "walking arrangement” cover a larger surface and also be concentrated to parts of the green-house where there is a demand for lighting.
  • the invention aims to give the biggest freedom to plan and build lighting installations through a precise operated parallel movement up and down along the whole construction without deviation from its linear form, or still with a vertical movement starting with a parallel movement down to be fulfilled with a lowering just in one end and the other end fixed.
  • the invention is characterised in that one from the hoist drum of the driving-unit running main-wire, after a final wire-pulley in its free end is given the function as object-wire for an object in the arrangement, that can as well be an armature, a counterweight or a component in the system, which is taking part in the balancing of the system already during the stage of installation, and in that the construction is furnishing pulling force in two opposite directions along the full length of the installation.
  • Object-wires running through their object-block, with armatures as load or arrangement for pulling power supplying cables can then within the capacity of the driving-unit be attached to the main-wire for respective lifting, moving or rotating functions in desired directions.
  • Installations in accordance to the invention can also be constructed as self-lifting devices independent of length.
  • the advantage with this construction is that also the driving unit is available for service and maintenance in lowered position and that alternatives are possible to construct so the installation can be called down without motor engagement just by using the safety braking devices. This alternative is shown as fig. 2.
  • a lighting installation constructed in accordance to the invention can easily be placed hidden between the ceiling of the building and a second ceiling with minimal openings for object-wires and cables for power supply and for operation. It is possible to arrange for these cables to remain hidden when the lighting installation is in its upper operational position. This is shown in fig. 3.
  • An installation in accordance to the invention can comprise of:
  • the invention offers this to a great extent since what has to be lifted are merely the blocks with their corresponding wires to be fixed to the structure of the facilities to pre-prepared locations where they can be attached e.g. with shackles.
  • the real load - the armatures or other objects - can afterwards be installed from floor-level on to the lifting-device.
  • a possible alternative with the invention is a free-hanging lift-arrangement without support from or engagement of the walls of a building which is shown in fig. 1
  • This alternative can be advantageous for use in less stabile building structures e.g. so called "balloon-halls" without supporting construction.
  • the arrangement is in accordance to the invention built as a frame onto which the driving unit is attached. Appearing forces are all handled within the lifting device and will not influence the wires which the arrangement is attached to the ceiling with more than by its weight.
  • the invention allows the installation of lifting-devices in wire perpendiculars where the height to the ceiling is significantly higher than the height the lighting-installation is to be placed.
