Definitions

  • the invention relates to a hollow body mast, in particular for attaching lighting fixtures, with an elevator for the transport of people and / or materials.
  • the masts For lighting places, e.g. Sports stadiums are used for lighting fixtures attached to masts. Depending on the size of the space to be illuminated, the masts reach heights of 35 m and more.
  • the lighting equipment must be serviced or replaced if it fails. Usually, several masts are required.
  • Climbing masts designed as hollow bodies with a closed construction is only possible with crampons or other driving devices provided thereon.
  • Traction sheave winches are also known which are used, for example, for lifting and lowering suspended scaffolding in the construction sector. The carrying rope is guided over traction sheaves and the winch moves along the rope without being wound up.
  • the invention is therefore based on the object of proposing an inexpensive personnel and / or material transport device for a hollow body mast for carrying out maintenance work, which can be used for several masts and in which as few pieces of equipment as possible are to be arranged in a stationary manner on each mast and these are protected and kept ready.
  • a temporarily attachable transport basket is provided according to the invention, which can be raised and lowered by a traction sheave winch on a support cable.
  • a safety cable ensures that the transport basket is intercepted in the event of failure of the support cable or the traction sheave winch.
  • the receiving and fastening device provided in the interior of the mast serves to receive and fix the retracted support rope and safety rope.
  • the carrying rope and the safety rope remain on the mast and are kept inside when the elevator is not in use.
  • the carrying cable and the safety cable are led out of the mast via deflection rollers arranged on the head of the mast and can be guided to the foot area of the mast in any case when the elevator is used.
  • a platform is preferably attached to the head of the mast, which facilitates maintenance work.
  • the deflection rollers are not attached directly to the head of the mast itself, but to a cantilever arm arranged on it
  • the stage is provided with a recess in a further embodiment of the invention.
  • the transport basket moves into this recess.
  • the transport basket also has a door to make it easier to get on and off.
  • the ropes can be pulled in by hand or a winch can be provided as the receiving and fixing device, which is arranged in the interior of the mast.
  • the winches for winding up the ropes can be designed simply because they do not themselves perform a lifting function for the loaded transport basket. If the rope is pulled in by hand, fixing points must be provided for the ropes.
  • the fixed winch is arranged inside the foot area of the mast.
  • the winch is therefore easily accessible, but is protected from unauthorized persons in the inside of the mast. Furthermore, it is also protected against weather influences. like the pulled ropes.
  • a reserve rope is provided which is retracted and kept ready.
  • a rollover device can also be provided.
  • a separate winch is preferably assigned to the reserve rope
  • the transport basket cannot swing in an uncontrolled manner during its movement, it is provided with guide rollers for support on the outer surface of the mast. If ropes are provided that must be pulled in by hand, the ropes are provided with an eyelet and the mast with hooks for hanging the eyelet when the ropes are retracted.
  • the mast shown in FIG. 1 is made as a hollow body with smooth outer surfaces and is welded together, for example, from plates. As can be seen from the cross section according to FIG. 4, the mast 1 is octagonal and its cross-sectional area decreases from its foot region 2 to its head region 3.
  • the mast 1 is provided as a lighting mast.
  • a platform 4 is attached in its head region 3, which can be walked on and carries the lighting body 5.
  • a cantilever arm 6 is attached to the head region 3 of the mast 1, which has two deflection rollers 7, 8 arranged next to one another at two positions.
  • the foot region 2 of the mast 1 is attached to a foundation 21. In the 1, the support rope 10, the safety rope 11 and the reserve rope 12 are retracted, that is, they are located inside 22 of the mast.
  • the ropes 10, 1 1 , 12 are each provided with tensioning weights 13 which, when the transport basket 14 is not in use, are attached to the support rope 10 and the safety rope 11 in order to ensure that these ropes 10, 11 are pulled in after the latter that they are guided for the reuse of the transport basket 14 after loosening their securing back to the base area 2 of the mast 1 under the load of the tensioning weights 13.
  • the transport basket 14 consists of a platform 15 with a railing 16 and is fastened to a support frame 17.
  • the support frame 17 can be implemented on wheels 18 from one mast 1 to another mast 1.
  • the supporting frame 17 has two further sets of deflecting rollers 19, 20 arranged next to one another for the supporting rope 10, the securing rope 11 and if necessary. the reserve rope 12 on.
  • the support cable 1 0 and the safety cable 1 1 are led out of fixed points 21 in the interior 22 of the foot region 2 of the mast 1 to the sets of deflection rollers 7, 8 on the cantilever arm 6 on the head region 3 of the mast 1 . This also applies to the reserve rope 12.
  • the carrying rope 10 and the safety rope 11 are led down on the outside of the mast 1 to the foot area 2 thereof.
  • the support cable 10 is connected via the deflecting rollers 19, 20 to the drive pulleys 23, 24 of a traction sheave winch 25 of the transportation rack 14 is attached also to the supporting frame 1 to 7, performed.
  • the traction sheave winch 25 provides for the upward and downward movement of the transport cage 14.
  • the safety rope 11 is also guided via two further deflecting rollers 19, 20 to a safety device 26, which serves to hold the transport cage 14 in place in an emergency.
  • the support frame 17 is also provided with guide rollers 27 which are supported on the outer surface of the mast 1. The arrangement of the rollers 27 in conjunction with the octagonal design of the mast 1 ensures good lateral guidance of the transport basket 14.
  • the stage 4 arranged at the head of the mast 1 has a recess 28 which is adapted to the size of the transport basket 14 and into which the transport basket 14 is moved, which causes the basket 14 and the stage 4 to be climbed safely.
  • the backup cable 12 is kept pulled in a rule, for the case that one of the other ropes 10, 1 1 is damaged or pulled by mistake via the guide rollers 7, 8 out into the mast 1, for example because no tension weight was attached. 13
  • the ropes 10, 11, 12 can each be provided with a further eyelet for the retraction, which is arranged along the length of the ropes so that after the retraction the eyelets are attached to the ropes 10, 22 in the interior 22 of the foot region 2 of the mast, 11, 12 can be attached.
  • the interior 22 of the mast 1 can be reached through a door.
  • the tensioning weights 13 attached at their ends are then immediately in front of the set of deflecting rollers 8.
  • a winch can also be provided in the area of the fixed points 21, which is used to anchor and wind up the cables 10, 11, 12. This can be a manually operated winch, since only a winding function for the ropes is required for the state of rest.
