Definitions

  • the invention relates to a device on ladder sections, which can be plugged together to form an assembly ladder, for fastening the ladder sections to a mast.
  • Assembly ladders are used with concrete or wooden masts, as these are usually not provided with a fixed ladder.
  • the assembly ladders are put together from ladder sections, with each ladder section usually being fastened to the mast by means of a lashable belt or chain which is placed around the mast. Because of the belt or chain placed around the mast, such assembly ladders cannot be used with masts on which the transition from an overhead line to an earth line takes place.
  • the cable is routed into the ground along these masts. The line is usually routed on the outside of the mast and would therefore be crushed or chafed by the belt or chain.
  • the invention has for its object to provide a device for attaching the conductor sections of an assembly ladder to a mast, in which there is no risk of damage to lines that are guided on the outside of the mast.
  • the device according to the invention has two clamping brackets which are penetrated by a rail at one end, the first holding bracket being connected to the rail in an articulated manner and the second holding bracket being displaceable along the rail, and a tensioning device which fastens the rail rotated relative to the first clamping bracket and thereby tensioning the two clamping brackets against each other.
  • the two clamps form a pair of pliers that clasp the masts.
  • the two front ends of the clamps keep a sufficient distance so that a cable can run between them on the outside of the mast without the risk of damage to the clamps.
  • Due to the displaceability of the second clamping bracket along the rail the device can be adapted to different mast thicknesses.
  • the rail usually has the shape of a flat iron and is guided through correspondingly cut out openings at one end of the clamping bracket. In order to achieve a certain rotatability of the first clamping bracket with respect to the rail, the opening in the first clamping bracket is slightly enlarged in the direction of the plane of rotation.
  • the tensioning device presses the end of the rail projecting beyond the first clamping bracket away from this clamping bracket and can consist, for example, of a cam of an eccentrically mounted disk or the like.
  • the second clamping bracket is therefore expediently provided with a guide piece resting on the rail, which prevents the second clamping bracket from tipping away in the direction away from the first clamping bracket.
  • the front end of the first clamping bracket is preferably connected to the conductor via vertically projecting connecting brackets. So that the conductor pieces take up as little space as possible for transportation, the connecting brackets can be articulated on the ladder so that the device can be folded to the ladder.
  • the fastening device according to the invention is particularly suitable for single-rail ladders according to DE-C-1 961 757.
  • the fastening device serves to individually connect the conductor sections, which can be plugged together to form an assembly ladder, to a mast 11.
  • the exemplary embodiment is a one-spar assembly ladder, of which only the profile spar 10 is shown in section.
  • the fastening device has a first and second clamping bracket 1, 2, which clasp the mast 11.
  • the two clamps 1, 2 are connected by a rail 3.
  • the two clamps 1, 2 and the rail 3 lie in one plane.
  • the first clamp 1 is articulated near the one end of the rail 3 by a bolt 12 on the rail 3.
  • the second clamping bracket 2 is slidable on the rail 3, whereby the fastening device can be adapted to masts of different diameters.
  • the clamps each have three sections. Their respective first sections have openings 13, 14 through which the rail 3 is guided. These first sections run parallel. To clasp the mast 11, these first sections are followed by second sections that strive away from one another, and which in turn are followed by third sections that converge. The second and third sections have approximately the same length.
  • the clamps 1, 2 are reinforced by welded-on flanges. On the first clamping bracket 1, two flanges 15 are welded above and below the opening 13 and it extends over this opening 13, so that at the same time they accommodate the bolt 12, which establishes the articulated connection with the rail 3.
  • this flange is welded at the level of the opening 14 and extends a bit parallel to the rail 3, so that it serves as a guide piece 16. He prevents the second clamp 2 from tilting away from the first clamp 1.
  • the two clamps 1, 2 are bent somewhat away from each other overall, so that there is a greater distance between the front ends, ie between the third sections than between the rear ends, ie the respective first sections. As a result, there is always sufficient space between the front ends for a possible line on the outside of the mast 11.
  • a tensioning device is provided to rotate the rail 3 in FIG. 1 clockwise around the bolt 12 with respect to the first clamping bracket 1.
  • the clamping device consists of a threaded piece 6 welded to the end 4 of the rail 3 lying at the first clamping bracket 1, into which a bolt 7 with a handle 8 is screwed.
  • the bolt 7 is screwed in until it presses against the second section of the first clamping bracket.
  • a further turning of the handle 8 then has the consequence that the tensioning device tries to turn the rail 3 in FIG. 1 clockwise.
  • the mast 11 is enclosed between the two clamping brackets 1, 2 and the conductor section is fixed on the mast 11.
  • the assembly ladder has a single spar, a profile spar 10.
  • Two connecting brackets 9, which are welded to the third section of the first clamping bracket 1, are articulated thereon via an articulated connection 17.
  • the connecting bracket 9 extend in the assembled state at an angle of about 20 ° upwards.
  • the connecting brackets 9 are connected by a web 18, which serves as a stop in the assembled state and in the applied state, ie when the fastening device is folded for transportation to the conductor section.
  • the fastening device is arranged in each case in the upper region of each conductor section, the lowest conductor section having a second fastening device at the lower end.
  • the conductor sections can have a length of e.g. 1.4 m, the lowest section of the ladder has a length of e.g. 1.8 m.
  • the fastening devices are first folded away from the conductor sections. Then the second clamp 2 is pushed on the rail 3 so far away from the clamp 1 that the fastening devices can be attached to the mast 11. The second clamp 2 is moved by hand as far as possible to the first clamp 1. By screwing in the threaded bolt 7 by means of the handle 6, the two clamping brackets 1, 2 are clamped against one another so that they clasp the mast 11 tightly.
  • the part of the assembly ladder that has already been erected is climbed. A person standing on the ladder can easily reach the rotary handle 8 with his left hand.
  • repairs can be made to lines running vertically on the outer surface of the mast, or such lines can be laid between the front ends of the two clamps.
  • All parts of the fastening device are suitably made of sunk steel.
