Definitions

  • the invention relates to a lifting platform with a platform which is supported in a height-adjustable manner on at least one supporting mast and which is connected to the mast (s) which can be assembled from stackable mast elements by means of a slide which can be driven.
  • these lifts are primarily of single-mast design, but two-mast designs have also become known.
  • the lifting masts of these lifts can each be set up from a base element supported on a base frame by stacking individual mast elements on top of one another with the aid of the platform that is raised up to the desired height or the predetermined height specified by the building to be processed.
  • the platform can also be assembled by stringing together individual platform elements up to a certain maximum size, but depending on the one or two mast design, is permanently connected to or to the mast (s) with one or two sledges, so that the platform or the sled sits on the foot element of the masts, resulting in a transportable basic lifting device that can even be moved when the frame is designed as a chassis, which, when in use, is expanded and enlarged in a modular manner due to the mast and platform elements available and to the respective structural conditions and Working conditions can be adjusted.
  • Rack-and-pinion drive devices provide safe, interference-free travel of the platform along the support masts, with appropriate guides and safety devices ensuring safe operation, and these lifts have already proven themselves in a wide variety of facade work up to the greatest heights.
  • the lifts allow working with an optimal access height, they offer large platform areas and thus space for material, aggregates, machines, etc., they form a uniform elevator for people and materials, they enable better working conditions in terms of health and social considerations , they leave a building essentially unaffected despite the facade work to be carried out and, last but not least, unauthorized use of these lifts is largely ruled out.
  • the lifts have so far been limited in terms of their lateral reach and to capture the maximum platform length of building and facade areas, the lifts would have to be dismantled and laterally rebuilt or lined up side by side, which is not only cumbersome, but also complex and often uneconomical , because if multiple stages were used, not all stages would be fully utilized at the same time.
  • the invention is therefore based on the object to eliminate these deficiencies and to create a lifting platform of the type described, which is distinguished without any impairment of its stage-specific advantages by the rational increase in its range and its variability with regard to the possible uses.
  • the invention solves this problem in that more masts are provided as sledges and sledges and / or masts have a coupling device for the optional connection of the platform to various supporting masts.
  • the measure according to the invention to make the platform decouplable from its originally assigned mast, at the same time opens up the rational possibility of being able to assign any number of masts to a platform, and then allows a single platform to be combined with different masts as required and this platform optionally there use wherever it is needed.
  • the individual masts are assembled in the usual way with the help of the platform, with each mast being based on its own base frame, and the platform, together with each of these masts, can fully meet all the requirements of a lifting platform.
  • the drive and control devices of the lifting platform are accommodated in the slide of the platform, these devices can also be used together with each of the various masts and despite the practically arbitrary range extension, the additional effort required remains relatively low.
  • the coupling devices required for removing or attaching the platform from or to the masts can be designed in a wide variety of ways; they merely have to ensure that the slide and mast interact properly after attachment and that the interacting guide and drive parts are easily separated when removed.
  • the carriage could be equipped, for example, with support parts which can be moved from an operating position into an open position and which, in the operating position, reach around or behind the carriage guides of the supporting masts and release them in the open position.
  • support parts could be swiveling roller systems or other slide parts interacting in a form-fitting manner with mast guides, which would in principle enable the known supporting poles to be used further and would only require a suitable retrofitting or conversion of the conventional sledges.
  • the supporting masts are constructed on a base element which, as a coupling device, forms a receptacle for an interchangeable element which is adapted to the mast elements with respect to the slide guide and drive parts and which is connected to the lowest of the mast elements attached to the base element.
  • the interaction of the interchangeable element and the base element makes it possible to use conventional slides and conventional mast elements built on the base element, since the sled for moving from mast to mast is simply moved onto the interchangeable element and is moved together with this interchangeable element, which is common to every mast with the base element to a certain extent replaced the foot element of the conventional masts. From the interchangeable element, the carriage or the platform can then be raised without difficulty onto the subsequent mast element and from there further along the mast.
  • the known lifting platform system can be converted according to the invention with little additional effort, since only one of the usual mast elements has to be built onto the upright part of the base element and a serving as an interchangeable element Mast element on one of its long sides is to be opened for placement on the upright part, in order then to be able to be fastened in the usual way to the underside of the lowest mast element.
  • the platform can be equipped with a chassis for moving, the platform being supported on the chassis via a lifting device, so that, without additional aids, such as, for example, truck cranes, the platform can be removed from one of the masts, brought to the desired location and reconnected to the corresponding mast, which is why the sled with the lifting device can be easily brought to the correct coupling height for coupling and uncoupling.
  • the undercarriage can be rail-free but also rail-bound and it can be moved manually or by motor or the like, so that an optimal adaptation of the platform change to the respective circumstances is possible.
  • the lifting platform 1 shown comprises a platform 2 and at least one supporting mast 3, the platform 2 being vertically movable on the masts 3.
  • the platform 2 can be assembled in a modular manner from platform elements 2a, which can be strung together on both sides of a basic element 2b up to a certain maximum length, the basic element 2b being connected to the supporting mast 3 via a drivable slide 2c and being guided along this.
  • the support masts 3 can also be built up from individual stackable mast elements 3a to the required height, each of the elements 3a having corresponding slide guides 4 and being provided with adjoining rack sections 5 for the slide drive.
  • the platform 2 connected to a supporting mast 3 can therefore move up and down along the slide guides 4 via its slide 2c, the drive device 6 of the slide 2c having a pinion (not shown further) which engages in the toothed racks 5.
  • the carriage 2c can be uncoupled and coupled from the mast 3 or to the mast 3.
  • the support masts 3 are built on a base element 3b, which as a coupling device 7 has an upright part 8, which forms a receptacle for an interchangeable element 9.
  • the interchangeable element 9 is aligned with the other mast elements 3 and, in order to take over the slide 2c, also has drive and guide parts 5a, 4a aligned with the toothed racks 5 of the mast elements 3a and their slide guides 4.
  • the interchangeable element 9 can now be placed with a lifting device (not shown), for example a truck crane, together with the connected slide 2c with the open longitudinal side 10 on the correspondingly narrow upright part 8 and with conventional connecting parts 11 on the underside of the upright part 8 attached mast element 3c, as shown in FIGS. 4 and 5 for an interchangeable element with a carriage 2c indicated only by dashed lines.
  • a lifting device for example a truck crane
  • the platform 2 is to be used on another supporting mast 3, this platform only needs to move the supporting mast down to the interchangeable element 9, then the platform is held by a lifting device, the interchangeable element 9 is removed from the mast element 3c and the platform with interchangeable element 9 is removed from the base element 3b and to be brought to the next mast 3.
  • the connection is made like any other Support mast by placing the interchangeable element 9 on the upright part 8 and connecting to the mast element 3c constructed on the upright part and the desired lateral offset of the platform 2 is finished.
