Definitions

  • Height-adjustable shelves are already known single or several next to each other lying platforms exist and each one or even several lifting devices assigned to them and their Drive devices need. Will be great for Floor areas a variety of such individually adjustable platforms, results from this inferring the same number of expensive Kraft.- or hand-operated actuators and drive units, as well as their assigned control and safety-related Facilities. As a result, in addition to the high Manufacturing and assembly costs as well as maintenance expenses very high. Also the need for large ones required Amounts of energy with the associated high From an economic perspective, providing energy is not sensible.
  • the instantaneous conversion of a floor area using a larger number of individually height-adjustable platforms with a singular or relative to the number of platforms lower number of hoists and drive machines and the hoists and platforms like that to design that the hoists are not each at one Platform are bound, but relative to the platforms are mobile, and the platforms and hoists for the purpose the conversion is currently merged, and after one the platforms were converted using support devices supported, and the hoists again from the Platforms are solved, and for subsequent adjustment other platforms can be used.
  • the one motor mobile hoist includes which in a basement is arranged below several platforms and in one horizontal travel axis can be moved under the platforms and a vertical stroke axis is controllable.
  • the hoist including the chassis because of the platforms that obstruct the view by an operator who is during the operation must stay below the platforms in the machine room below the load center of the individual platforms by Visual contact can be placed, which makes it even more difficult is due to the fact that the drive system is lacking Brake device a certain even when it is switched off Has caster.
  • An exact placement and posture of the Hoist could even when using a brake Locking the wheels will not result, as ever according to the speed and weight of the mobile The hoist cannot rule out sliding or slipping is.
  • the support devices not permanently with one as before the structure supporting the platforms are anchored, but the platforms P, by means of a height adjustment portable or positionally movable support devices S, are supported, and the support devices do not like have so far been permanently installed in a basement and the top end of which is not fixed below one built-in floor, but the support devices S, and their arrangement are designed in such a way that these with their platforms P, facing Stop S10, over the top F10, one of the Platforms P, surrounding floor F1, can protrude or can be carried out, or the support devices S, with their respective platforms P, facing Stop S10, over the top P10, from neighboring platforms P, protrude, or out can be performed.
  • the support devices S are preferably not made of known from DE 25 45 074, permanent and rigid with one Structure connected, but are portable, or changeable, i.e. They are used to support the Platforms P, to these, or their arrangement area guided, or are movable with the platforms P ,. connected and carried by the platforms P, and with the platforms P, with.
  • both sideways outside of the platforms, as well as below the Platforms can be arranged. It is particularly advantageous the support devices S, preferably in a new arrangement to be placed below the platforms P, and in the manner to design that the same does not have the outer End faces P11, the platforms P, protrude, whereby several platforms P, with their outer end faces P11, even immediately after two or more outer sides are lined up, and between the platforms P, no annoying protrusions or larger Spaces arise, but the platforms P, with lateral distances a few millimeters, or directly built up against each other, or strung together can.
  • Another advantage of the invention is that due to the movable support devices S, the platforms P, both mobile, as well as stationary or localized within of a building can be arranged, and at one Distance of the platforms P, none from their place of operation open pit or basement, or permanently with a floor F1, or structure firmly anchored and obstructing supports remain. For example, it is possible that in Buildings that do not have sufficient installation space inside their surrounding walls or their permanently installed Floor space for the integration of the platforms P, have, or a sports floor is present, which none Joints may have that the platforms P, (Fig.
  • Platforms P during their height adjustment to the mobile Hoists H, tied up and fixed against them the mobile hoists H, by means of vertically acting Management bodies take on the management function, and the Platforms P, by means of the fixing elements P3, against the mobile hoists H, are fixed out, and a side Move platforms P relative to their surroundings or to the mobile hoists H is prevented.
  • the platforms P, and a die Platforms P immediately surrounding structure F1, or dormant structure organs and facilities for management and spacing, e.g. Sliders or Slide rails, or rollers for guidance and spacing are classified.
  • the mobile hoists H both from the outside P11, the Platforms P, or from the tops P10, of the platforms P, can be brought up to this. So it is e.g. in some structures not possible below the platforms Machine rooms or travel areas for the mobile hoists ready to deploy or bring in so that a feeder or coupling the mobile hoists to the platforms only possible from the outside or the top is. In most cases, however, it is desirable that the mobile hoists H, arranged below the platforms P. are.
  • the mobile hoists H are fed precisely to the Platforms P to ensure are the mobile hoists H, preferably in guideways H5, which are below the platforms P, extend.
  • the guideways H5, in their length are dimensioned so that they over the Arrangement area of the platforms P, lead out, and the mobile hoists H, in one of the platforms P, not overlaid area F4, can be guided, and in this area is accessible to maintenance personnel and the like are.
  • Another advantage of the arrangement area of the Platforms P, extended guideways H5, is the possibility (Fig.
  • Interlocks H10 with mutually interlocking preferably conical guide surfaces are provided, that the mobile hoists H, during a Locking in an exact and in the same place repeatable position relative to the platforms set up automatically, and temporarily, quasi stationary with a resting structure or a Foundation floor F2, or the guideway H5, are connected.
  • holding positions are arranged along the travel route and assigned to the arrangement areas of the platforms P and assigned to the position of the platforms P.
  • These stop positions are preferably marked by means of mechanical, electrical or electronic position marks C1, and monitored by a controller C, it being possible for position-giving switch contacts or proximity switches and the like to be assigned to each stop position, or the route is detected by means of electronic path measurement, and the The length of the route is subdivided into individual stops in the form of optical or magnetic scales and the mobile hoists each lead past the scalings and their current driving position is continuously recorded, and with the help of a higher-level control device C, the mobile hoists into the respective platforms assigned and controlled scaling area, and come to a standstill automatically in this.
  • the length of the route is recorded with other contactless measuring devices, for example with a laser beam, which enables a distance measurement relative to a reference point.
  • the travel drives of the mobile hoists H can not only be driven at one speed as before, but that the driving speed can be varied step-wise or continuously, which means that longer distances with greater speed (rapid travel ) are put back, and when approaching a target point or stopping position the speed is reduced and the last part of the journey to a target position or stopping position takes place at a greatly reduced speed relative to the rapid traverse, as a result of which the mobile hoists H become more dynamic as a result Force forces more precisely into their target positions or working positions and have them stopped, and an unwanted overrun of the working positions or target positions relative to the platforms P can be excluded.
  • the mobile hoists H are driven with traction motors and the traction motors have a step-by-step or continuously variable speed.
  • Another advantage of the position markings C1 along the route is that the mobile hoists H are no longer controlled in their working positions by eye and hand command, as in DE 25 45 074, but the mobile hoists H are automatically in their respective working positions are controlled relative to the platforms P, and the control device C (FIGS. 1, 3, 11) can also be arranged above the platforms P or outside the machine rooms, and the operator during the height adjustments from outside or above the machine rooms can control the mobile hoists H,.
  • the control device for command and control the mobile hoist H is preferably a so-called Computer control C, which has a data memory and a electronic data processing unit, and a keyboard for entering control commands or in addition to Retrieval of programmed control commands.
  • Computer control C which has a data memory and a electronic data processing unit, and a keyboard for entering control commands or in addition to Retrieval of programmed control commands.
  • the platforms P can be raised or lowered done according to the invention in different ways.
  • the mobile hoists H by means of stop elements or Articulation elements on the movable support devices S, attack and link them and straighten them up or lower while the movable supports in turn link and carry the platforms.
  • the platforms P are preferably facing Stop sides of the mobile hoists H, and the mobile ones Hoists H, facing stop sides of platforms P, with stop and fixation elements P3, which in mutual approximation, so that these interacting in pairs under constant Approach and subsequent contact horizontally positive, or almost positive Establish contact.

  • This new solution has the particular advantage that maximum only as many power-operated actuators H8 are required become, like a platform P, or support device S, Locks S7, has, and is therefore on the one hand the number is particularly economical and secondly possible sources of error or sources of interference are reduced.
  • This advantageous measure does not, as in DE 25 45 074 described only a hoist with a Shown lifting drive, but the mobile hoists H, carry and carry additional actuators H8, or actuators to set up the Support devices S, and for actuating the locks S7, with itself, and their functions are not just for that Raising or lowering the platforms P, provided, but equipped to perform multiple functions, and to multi-functional mobile lifting robots.
  • This configuration is particularly advantageous in connection with the computer control C, since now in a new way, the entire structure of a height-adjustable floor area can be done fully automatically, and the driving movements and lifting or lowering and setting up and Locking or unlocking the support devices S, can be done programmatically, after which the mobile hoists H, trained as a robot, all to build up the floor area can perform the required operations independently.
  • the function monitoring or end position monitoring of the Locking S7 preferably does not take place as in conventional platforms directly through control bodies, which are permanently connected to the platforms P, but these are in a new way (without drawing) also with the mobile hoists H, or on the mobile ones Hoists H, with guided, and to the platforms P, or Support devices S, and their interlocks S7 guided.

  • the effective lengths are shorter than the lifting arms H4, the lifting scissors.
  • auxiliary links H11 are from the Several types of auxiliary lifting devices have been used in the past known for flat-construction lifting scissors. So there is e.g.
  • Lifting wedges that initially engage the lifting arms, or rotatable or swiveling link levers, which the Link the lifting arms from their lowest position and support, or cam rollers, which between the Scissor arms an ever-widening wedge mouth form, or in addition to the main stroke drive upstream short-stroke drives or pressure elements.
  • lifting bags or lifting bellows which squeeze flat in the rest position, or lay together and expand with a pressure medium, and thus cause an increase.
  • Auxiliary lifting devices are tried and tested in practice consequently for lifting the lifting arms from the lowest Position usable out. Thereby lose with increasing Erection of the lifting arms of the auxiliary lifting devices Effect and the articulation of the lifting arms is now directly from the drive elements of the main lifting phase.
