Definitions

  • the present invention relates to a working platform for use inside a tower-like structure.
  • a work platform is typically attached to a crane and introduced from above into the interior of the tower-like structure.
  • this is only possible as long as the upper end of the tower-like structure is open.
  • a use of a working platform on a crane is no longer possible. For example, since the tower of a wind turbine can reach a height of 100 meters, work inside the tower is not easily possible.
  • a working platform which can be used inside a tower-like structure, such as a tower of a wind turbine.
  • the platform has a scissors-like support structure. On this support structure, a work platform is arranged.
  • a working platform which can adapt to different cross sections. This is particularly important in tower-like structures whose cross-sections taper towards the top, so that the available area for a working platform varies accordingly.
  • the invention is based on the idea to provide a scaffold-like framework as a support structure for a working platform, which climbs upwards in the interior of a tower with the construction progress and has a working platform.
  • a work platform or indoor stage is advantageously used in towers, which are made of precast concrete parts.
  • the prefabricated concrete elements used for the erection of a tower have holders on their inner circumference, on which the inner stage or parts of the inner stage can be hung.
  • these holders are arranged at predetermined heights and distances. Holders may either have been pre-installed in the precast concrete parts, or they may be retrofitted.
  • the distributively arranged holders allow the work platform to behave analogously to a mountaineer who, during the ascent, hooks hooks above its position into a mountain wall and then climbs up to these hooks.
  • the holders are preferably mounted in advance, so that a working platform can quickly climb up or down on these holders.
  • an actuating element is arranged around the central support element around which acts on the lower scissor lattice bars resting against the central support element.
  • the actuator By the actuator, the lower scissors lattice bars can be acted upon with a tensile force. This leads to a retraction of the scissor lattice and thus a reduction in the size of the platform, so that it can be moved into a part of the tower with a smaller cross-section.
  • An application of the shear lattice bars with a compressive force leads to an extension of the scissor lattice and thus to an increase in the working platform. If the platform already passes through the entire tower cross-section and abuts the tower conversion, can be adjusted by the force exerted on the scissor lattice bars compressive pressure, with which the peripheral edge of the platform rests against the tower wall.
  • Fig. 1 shows a cross section of a tower-like structure with a working platform according to the first embodiment.
  • the building under construction 100 preferably a tower of a wind turbine, has two pre-fabricated precast concrete parts 10, 11, which are arranged on top of each other.
  • the working platform 50 is lowered into the interior of the tower-like structure.
  • the work platform 50 consists essentially from a support structure, which consists of scissors-like support arms, and a working platform 7.
  • Fig. 2 shows a cross section of a tower-like structure with a working platform according to the first embodiment. While in Fig. 1 a situation is shown in which the work platform is introduced into the interior of the tower-like structure is in Fig. 2 shown the situation in which the platform is extended and the tower cross-section completely penetrated. This is essentially achieved by extending the safety lattice-like support arms 5 until they touch the inner wall of the tower-like structure. In the lower area of the platform several Tirak winches 1 are provided. These are preferably attached to an outer end of each Scherengitterarms. On the platform 7, which preferably extends over the entire cross section of the interior of the tower-like structure, people and material and tools may be located. The platform 7 takes over the function of a working platform and the people can perform work steps there to build the tower-like structure.
  • Fig. 3 shows a further cross section of the tower-like structure with a working platform according to the first embodiment. While in the Figures 1 and 2 only two precast concrete parts 10 and 11 are already shown mounted, shows Fig. 3 the situation in which a further precast concrete part 12 is mounted on the two already assembled precast concrete parts 10 and 11.
  • 3 holders are provided in the inner wall of the concrete precast elements, are attached to which (not shown) ropes. These ropes run through the Tirak winches, so that the stage according to the invention can move in the vertical direction along the ropes by suitable control of the Tirak winches within the tower.
  • a power supply for the platform and their Tirak winches can z. B. be provided by a cable from below.
  • Fig. 4 shows a cross section of a tower-like structure with a working platform according to the first embodiment.
  • all three precast concrete parts 10, 11 and 12 are now mounted, and the platform 50 must be moved upwards to allow work in the upper finished part 12 and / or the installation of the subsequent precast concrete part.
  • one of the workers can climb up to the holder 3 of the inner wall of the third concrete precast element 12 by means of a ladder 15 in order to fix a rope of the Tirak winch 1 there accordingly.
  • a telescopic rod can also be used.
  • the number of holders 3 on the inner wall of the tower-like structure should be at least equal to the number of Tirak winches, so that the ropes of the Tirak winches can be attached thereto accordingly.
  • the brake is released in each case on a winch, so that the rope can be pulled upwards.
  • the rope is fixed again in the winch, so that the stage is also worn by this rope again. Thereafter, the next rope is released and hung in the corresponding upper holder 3, etc.
  • Fig. 5 shows a cross section through a tower-like structure with a working platform according to the first embodiment.
  • the scissors-like support arms 5 of the work platform can be seen.
  • the platform has rollers 16 (here 6 pieces) on the outside of the work platform. The rollers come then with the platform extended in contact with the inner wall of the tower-like structure, so that the platform 50 can be moved up or down more easily and damage to the tower inner wall and / or platform during movement is avoided.
  • the platform comprises a predetermined number of plates, which is larger by 1 than the number of support arms. All plates are the present embodiment circular. One of these plates encloses a central rod (see reference numeral 60 in FIG. 6 ) to close the middle part of the platform.
  • the remaining plates are each arranged on a support arm and secured to the outer end of the support arm. Furthermore, these plates are provided with a recess. This recess extends in the radial direction from the center of the plate in a straight line to the outside. In this case, the Auf originallyung on a width which is slightly larger than the diameter of the central rod. In situ, each of these plates is oriented so that its recess faces the central rod.
  • Fig. 6 shows a detailed sectional view of the platform according to the Figures 1 - 4 , Here, the scissors-like support arms 5 are extended on the right side. Thus, a larger inner cross section of the tower-like structure can be covered by the platform.
  • Fig. 7 shows a further detailed cross section of the tower-like structure with the work platform according to the first embodiment.
  • the platform is located within a precast concrete part 12 in the upper part of the tower-like structure.
  • the cross section of this finished part is smaller than the cross section of in Fig. 6
  • the scissors-like support arms 5 of the working platform adapt to the become smaller cross-section, when the platform is moved upwards by retracting.
  • an indoor platform or platform can be provided, which can climb up or down in the tower itself. For example, it is no longer necessary for a tower of a wind turbine, with a winch from the gondola in the basket up or drive down. Rather, now an indoor platform is provided, which can fully enforce the tower, and which can climb in a simple manner, where work is currently being carried out. Furthermore, it can be adapted to different tower cross-sections by the design of the safety lattice-like support arms 5.
  • the work platform preferably has a central rod 60 and scissor lattice / support arms 5 hinged thereto. On the support arms 5 plates 7 are arranged, which then form the working platform. Below the support arms, the so-called continuous winches or Tirak winches 1 are provided. With such Tirak or continuous winches, the aerial platform can climb up or down even on ropes running through the winches.
  • the ropes of the Tirak winches 1 are preferably attached to brackets 3 inside the tower-like structure, so that the Tirak winds on the ropes can run up or down.
  • several Tirak winches are provided on the circumference of the work platform.
  • To raise or lower the ropes of Tirac winches must be successively released from the brackets 3 and attached to the next higher or next lower holder, depending on whether the stage is to be raised or lowered.
  • at least five Tirak winches are provided on the circumference of the work platform, so that at least five ropes are provided with the corresponding brackets 3.
  • the platforms 7 of the work platform are preferably configured to overlap so that the work platform can accommodate the different cross sections within a tower-like structure.
  • each of the plates attached to a support arm has a recess which is aligned with the central rod and slightly wider than this, a retraction of a support arm with the associated movement of the leads corresponding plate 7 does not lead to a collision of the plate 7 with the central rod. Rather, the recess moves towards the central rod and picks it up.
  • the length of the recess is a measure of how far pushed together the platform or the scissors-like arm can be retracted.
  • FIG. 8 A simplified illustration of a plate 7 is shown in FIG. 8 shown.
  • rollers 6 on the circumference of the working platform 50 are provided so that the working platform rolls on the inside of the tower wall and does not scratch along there.
  • a working platform By adjustable in their cross-section platform a working platform can be provided, which adapts to the cross section of an upwardly narrowing tower-like structure.
  • the work platform described above proves to be particularly advantageous if a nacelle of a wind turbine is already arranged on the tower of the wind turbine and thus no longer has the opportunity to reach by a crane from above into the interior of the tower of the wind turbine.
  • the collapsible or disassembled working platform can be brought through the door in the lower part of the tower and constructed accordingly, so that they can then move up or down along the tower by means of the holder 3 located in the tower segments.
