Definitions

  • the invention relates to a lifting device for a platform for parking motor vehicles, in which the platform is carried by support chains which are raised and lowered via driven sprockets and are guided on the platform via guide rollers (FR-A-717691).
  • Parking devices for motor vehicles are known in which the vehicles are parked on lifting plates which are raised and lowered as required in an entry level (brochure Wschreib Auto-Parksystem Combilift 543 from Otto Wschreib GmbH, February 1985).
  • Lifting devices are known in which the platforms are held at all four corners on a chain or cable hoist, the chain or cable hoists acting on the four corners being wound up or unwound synchronously. This requires an increased design effort, since for this purpose either a separate winding device must be provided for each rope or because extensive deflection rollers must be arranged on the top.
  • a support chain is arranged on each side of the platform, one end of which is held stationary in the area above a corner point of a platform, hangs down from there and a first, on one side of the
  • the platform encompasses the freely rotatably mounted deflection roller, from it around a second deflection roller arranged at a distance from it, forming a loop, in which the platform hangs with the two deflection rollers, is guided upwards again and engages around a fixedly mounted drive wheel, and with a non-rotatably connected gearwheel connected to the second deflection roller, which has an essentially parallel to the stroke path, a fixed rack or a stationary one Guide chain combs, which rests on the side of the gear wheel facing away from the support chain.
  • a guide chain or a guide rack is additionally provided, which meshes with a toothed wheel, which in turn is non-rotatably connected to the deflection roller, which is attached to the run of the carrying chain which is guided over the driven chain wheels is present.
  • the corresponding deflection rollers are secured in every position against a rotational movement in both directions, so that a movement of the platform along the two carrying chains and thus a tilting of the platform around the transverse axis is avoided.
  • gear means for example gearwheels mounted on the platform, in which case the last gearwheel of the gear chain is in contact with the rack or the stationary guide chain.
  • the two deflection rollers are arranged at the front or rear corner point of the platform.
  • the vertical parts of the support chain can be arranged outside the platform at the front and rear ends, so that they are guided in the area of a frame or a wall of a building in which the system is arranged.
  • the drive wheels of the support chains arranged on both sides of the platform are held on a common drive shaft. This results in a synchronism on both sides of the platform.
  • the supporting chains can hang loosely from the drive wheels with their remaining strand. It is advantageous if the ends of the residual strand are held stationary, so that the residual strand forms a loop between the drive wheel and the attachment point, in which a sprocket tensioned downward is preferably held. This tension can be achieved, for example, simply by attaching a tension weight to the loose sprocket.
  • the gear meshing with the toothed rack or the guide chain has a pitch circle diameter which is the same as the diameter of the deflecting roller connected to it in a rotationally fixed manner, the inclination of the platform is retained during the lifting and lowering movement.
  • the gear wheel has a pitch circle diameter that differs from the diameter of the deflecting roller connected to it in a rotationally fixed manner. This makes it possible for the platform to be additionally pivoted about the transverse axis during the lifting and lowering movement, so that the inclination of the platform between the raised and the lowered position can be adjusted in this way. This can be convenient to connect a platform to an entrance and to incline them differently in the parking position away from the entrance according to the circumstances of the building.
  • the guide chain can also be placed in the vicinity of an end wall or a support frame, so that it essentially frees up the space next to the platforms. It is particularly advantageous if the chain also wraps around the gear on the top and / or the bottom.
  • the guide chain can, for example, rest on a carrier of a stationary frame and is only guided around the gearwheel arranged laterally on it in the area of the platform itself.
  • the system for parking motor vehicles is arranged in a building pit 1 with a floor 2 which is delimited by walls 4 which are opposite one another.
  • Four vertical posts with double T-profiles are arranged at the corner points of each parking space and extend from floor 2 to an entry level 5, which is at least one vehicle height above floor 2.
  • the posts 3 can also be made higher if a further parking level is provided above the entry level 5, but the principle of the invention is explained using a simpler embodiment which the posts only extend approximately to entry level 5.
  • a number of parking spaces are provided next to one another, the posts 3 between adjacent parking spaces each being assigned to these adjacent parking spaces.
  • horizontal rails 6 and 7 are arranged transversely to the longitudinal direction of the individual parking spaces, which extend over the entire width of the construction pit and on which platforms 8 run by means of suitable rollers, which are thereby laterally displaceable.
  • the number of platforms 8 in this level is one less than the number of parking spaces, so that the platforms 8 can be moved so that a parking space always remains free when needed.
  • the rails 7 on the opposite side of the parking space from the corresponding post 3 are arranged at a distance, so that between the rails 7 and the corresponding post 3 on the front side of the platforms 8, a free space 9 remains in which the lifting device for a arranged below the platforms 8 platform 10 can be arranged.
  • a platform 10 is assigned to each parking space; it is guided by guide shoes 11 at its corner points in the side walls of the posts 3 which are double-T-shaped in cross section, as is particularly clear from FIG. 3.
  • the guide shoes 11 are arranged at the free end of arms 12 which connect laterally to the corners of the platform 10 (FIG. 3).
  • each platform 10 On both outer sides of each platform 10, two deflection rollers 13 and 14 designed as chain wheels are arranged, these deflection rollers being mounted on the arms 12, that is to say essentially at the corner points of FIG Platform 10 are located.
  • the axis of rotation runs parallel to the rails 6 and 7.
  • a support chain 15, which forms part of the lifting device, runs on both sides of each platform 10. This lifting device is provided on both sides of the plate 10 in the same way, it will therefore be discussed in the following only on one side of the platform 10.
  • the support chain 15 is fastened with its one end 16 to the top of a post 3, which is located at the end of the construction pit 1 opposite the space 9.
  • the support chain extends directly next to the post 3 vertically downwards and runs around the deflection roller 13 to the rear deflection roller 14, from which it leads again vertically upwards to a drive sprocket 17, which wraps around the top.
  • the drive sprocket 17 is mounted behind the upper platform 10 in space 9 at the height of the entry level 5 on a drive shaft 18 which extends over the entire width of the platform 10 and which can be rotated by means of a drive motor 19.
  • the corresponding drive sprocket for the support chain arranged on the other side sits on the drive shaft 18 on the other side of the platform 10.
  • the free end or residual strand 20 of the drive chain hangs vertically downward after wrapping around the drive sprocket 17 and forms a loop 21, the end 22 being fastened to the rear post 3 (FIG. 1).
  • a tensioning wheel not shown in the drawing, to which, for example, a tensioning weight is suspended, can be mounted in the loop 21.
  • the support chains 15 form a loop on both sides of the platform 10, in which the platform is suspended by means of its guide rollers 13 and 14. Since the platform 10 is not fixed along the support chain 15, it can pivot about a transverse axis which runs parallel to the drive shaft 18 if the platform is loaded more at the front or at the rear end than at the opposite end.
  • a gearwheel 23 which is located, for example, on the same bearing shaft 24 (FIG. 3).
  • a guide chain 25 is looped around this toothed wheel 23, one end 26 of which is fixed to the floor 2 or to a foot part 27 connected to the post 3, from there the toothed wheel 23 is looped vertically upward, around a freely rotatable arm 12 mounted deflection roller 28 is deflected vertically upwards and is attached with its other end 29 to the top of the post 3.
  • This guide chain 25 thus has an essentially vertical course, the two vertical parts being laterally offset from one another by the deflecting roller 28 and the toothed wheel 23.
  • the guide chain 25 wraps around the toothed wheel 23 on the side that faces away from the wrap around the deflection roller 14 by the support chain 15.
  • the platform 10 is normally in the lower position shown in FIG. 1, in which it rests on the foot parts 27 by means of the arms 12, for example.
  • the platform 8 arranged above is first shifted laterally, so that a free space is created above the platform 10 to be lifted.
  • the drive motor 19 is actuated such that the two drive sprockets 17 move the support chains 15 running over them in such a way that the the pulleys 13 and 14 encompassing loops are shortened and the loose loops 21 are lengthened.
  • the lower platform 10 is raised, this platform 10 is shown in dash-dot lines in a raised position, as are the associated support chains 15.
  • the toothed wheel 23 meshes in the guide chain 25.
  • the platform 10 is raised parallel to itself when it is raised, that is to say without pivoting about the central transverse axis. This is the case when the pitch circle diameter of the deflection roller 14 matches the pitch circle diameter of the gear 23. If one chooses these pitch circle diameters differently, the platform pivots around the central transverse axis when it is lifted, so the platform is pivoted about this central transverse axis in a precisely defined manner. This may be desirable in certain applications, for example in order to achieve the connection of the front end of the platform to the entry level 5 before the entire length of the platform 10 is raised to the entry level 5.
  • the guide chain 25 is laterally offset from one another by the gear 23 and the deflection roller 28 in the lower and in the upper tell. It would also be possible to use a second To arrange the pulley below the pulley 28 and the lower part of the guide chain 25 exactly below the upper part of the guide chain 25, this guide chain would then only form a loop wrapping around the gear 23 between the two pulleys.
  • the guide chain 25 could also be replaced by a rack with which the gear 23 meshes.
  • This rack could be arranged vertically and stationary in the excavation pit, it would also be possible to mount it pivotably on one side and then to provide a guide which holds the pivotable rack with the gear 23 in engagement.
  • All devices of the lifting device namely drive motor, drive shaft, drive sprockets and deflection wheels including the guide chain can be arranged in the space 9 behind the platform, so that the upper platforms 8 can be moved laterally unimpeded by the lifting device.
  • a platform corresponding to the platform 10 with an associated lifting device could also be arranged above the platform 8, which could then be lowered accordingly if the platform 8 is laterally displaced.
  • the guide chain can be made much weaker than the two support chains, since it only serves to guide the platform along the support chain, but does not support it. Overall, there is a structurally simple, yet reliable arrangement, at the same time the synchronization on both sides is ensured by the connection via the drive shaft.
  • the parts of the lifting device arranged on the platform 10 itself can be arranged next to the platform, that is to say they do not require any additional depth in the construction pit 1. This allows the pit depth 1 to be fully utilized.
