Abstract

The parking garage has an approximate tower-form single or multi-story building with parking boxes(3-6), at least one combined drive-in and drive-out box(9,10) or at least one drive-in box and/or at least one drive-out box with its loading and unloading opening adjacent to a common transporting shaft which has a lifting appliance in which is installed a slide unit(17) equipped with a turntable(15). A separate drive-out box may be provided so that the drive-in box and drive-out box are separated from each other.

Description

The invention relates to a parking garage with a grate system according to the preamble of Claim 1. Such a parking garage is, for example, under the Subject of PCT / WO 94/11598 become known. In this known Parking garages are a series of rows and columns Parking spaces one above the other and side by side in the form of individual shelf towers arranged, each shelf space a shelf for the there vehicle to be stored.

The lifting conveyor is designed as a storage and retrieval unit. On a vertical, movable mast, which is clamped and movable on the floor and ceiling side is guided, a lifting carriage is arranged, which can be raised and lowered has telescopic sliding fork.

A fixed lifting table is assigned to this lifting and moving device, which part of the entrance and exit box is, the lifting table can be raised and lowered is designed and can also be moved in the horizontal direction by a Infeed movement on the telescopic sliding fork To enable lifting device.

The disadvantage of the known system is that such a lifting and lowerable, as well as movable lift table must be present to do that transporting vehicle at all in the field of telescopic Bring lifting device.

This must go through a shelf tower with the telescopic Grab the sliding fork to hold the now on the lift table and with to reach under the vehicle moving on the lifting table and to record.

So it is a very complex rust system because the vehicle is on a support grid of the lifting table rests and this support grid from the as Sliding fork trained lifting grate can be reached, so that Vehicle from the support grate of the lifting table on the sliding fork  can be taken over to then with the movable lifting device in the Shelf box to be moved.

As soon as the mobile lifting device has activated a free rack aisle, again the multi-telescopic lifting grate of the sliding fork is extended and the vehicle is parked on a shelf of a rack storage area.

If a vehicle is to be parked, then the one described above is done Process backwards, but this has the disadvantage that the vehicle to be parked in turn is placed on the lifting and sliding table must be, which then again with its horizontal movement in the Entry box is moved in so as to get the vehicle out of the entry box again to be able to drive out.

It follows from this that the loading and unloading capacity of the known parking garage is very limited because the lift table used for the entry and exit box is practically always on the move and while loading Vehicles can not be deployed.

Another disadvantage of the known solution is that the lifting device is a triple telescopic sliding fork has what with appropriate mechanical Stress with high machine expenditure and with corresponding Signs of wear are associated.

It must have a very large extension length of e.g. Ex. 5 m can be guaranteed because the known lifting device must accommodate the carriage in the direction of its longitudinal axis and thereby a recording length of 5 m or more for the sliding fork necessary is.

Incidentally, a relatively large telescopic length of the shift fork is also necessary because the lifting device can only be moved along the rack aisles, but not at right angles to this, by corresponding delivery movements for the storage boxes to enable.

The shift fork is otherwise on the hub by means of a turntable stored.

Because of the large extension length of the telescopic sliding fork there is the disadvantage that the positioning of the lifting device in front of a shelf box very much  must take place exactly, because already a small angular misalignment of the Turntable for a large entry error of e.g. Ex. +/- 50 cm at the front end of the 5 m long sliding fork.

Due to the fact that the lifting device both on the bottom and Clamped on the ceiling side, a very large overall height is created corresponding, large masses to be moved, what the Moving speed of the device decreases.

Another disadvantage is that the known parking garage on the use of a movable and liftable and lowerable lifting table, which is the Picking up the vehicle from the entry and exit box and in the area of Shelf aisles in order to drive the vehicle towards the mobile lifting device to hand over. This results in long transport times and correspondingly longer ones Manufacturing costs for such a parking garage, because the lifting device as a separate part is relatively expensive.

Because of the need to move the lifting and lowering table in the area of the aisle and the need to extend the Telescopic fork over a length of z. Example 5 m, also result in long Delivery times because the parts mentioned are only moved to their end position have to be handed over from the lift table to the lift fork before a car can.

DE 42 14 632 A1 has disclosed another parking system with grates, where the vehicle is also in the longitudinal direction of a corresponding one Lifting rust is picked up.

This system uses a vertically movable floor conveyor with one appropriate storage rack.

Rails are arranged in the parking devices (parking boxes), one Transfer from the rails in the parking boxes to the floor conveyor takes place that the rails are horizontally movable and from one Towing device can be pulled out of the parking boxes or into the parking boxes can be pushed in. The towing device is on the floor conveyor arranged.  

There are pallet-like and plate-shaped storage devices, which with the floor conveyor and a towing device arranged in it from the the respective parking box can be pulled out and pushed into the floor conveyor can.

This is very expensive because each parking space such, pallet-like storage device must be assigned.

The same criticism also applies to PCT / WO 98/39536 because there is also a Pallet system is described, which has the said disadvantages.

The invention is therefore based on the object of having a parking facility Grate system based on the PCT / WO 94/11598 so that with much simpler means a higher turnover rate with lower Manufacturing costs and can be achieved with less energy.

To achieve the object, the invention is through the technical teaching of Claim 1 marked.

An essential feature of the invention is that it can be raised and lowered Sliding device mounted on a turntable driven sliding fork, which is designed as a grate and the is suitable for a vehicle located on a storage rack reach under and take over or hand over to the storage rack and to turn off.

This gives significant advantages over the prior art, because it is not initially necessary to telescopic the sliding fork to train. Simply moving the sliding fork on one is sufficient Carriage of the lifting conveyor, because it is possible that the sliding fork extends beyond the lateral limits of the lifting conveyor and a Vehicle standing on a storage rack outside the lifting conveyor to take hold of and take over immediately.

So there is no need to design the sliding fork as Telescopic device also because the invention provides that Vehicle is attacked from its broad side and not from its long side as taught by the prior art.  

This has the advantage that, because of the lack of telescopability the shift fork now has significantly higher takeover speeds be guaranteed, because the sliding fork with your slide drive driven directly under a vehicle on a storage rack and that Vehicle can be taken over immediately.

At the same time, this also means that the invention uses a lifting device. and lowerable and movable lifting table.

According to the invention it is provided that the entry box, which the Represents access to the parking system, is designed as a storage rack, so that the vehicle can drive directly into an entry box for parking, and stops there on a shelf.

The present invention is therefore a parking garage with Grate system consisting of a three-dimensionally usable shelf warehouse Shelf boxes designed to accommodate vehicles with rust-like bottom, feed system with also rust-like entry and exit Delivery device, designed as a tower-shaped, single or multi-storey structure from storage boxes with at least one entry box and at least one exit box whose loading and unloading openings adjoin a common conveyor shaft, which has a lifting conveyor device, in which one with a rotating device equipped displacement device is arranged.

The displacement device arranged in the lifting box, which holds the displacement fork drives, now directly engages this vehicle on the storage rack, takes over it and it can be turned into any by appropriate lifting drive of the lifting box Move the shelf height to a parking space there (always in the transverse direction) to discontinue.

It is also important that the sliding fork is arranged on a turntable, because due to this feature, the vehicle can be in any Turn position in a suitably oriented storage box. this leads to also to the advantage that in addition to the entry box, a separate exit box can be provided so that the entry and exit boxes from each other are separated. This also substantially increases the inputs and Parking speeds, because the lifting conveyor can now drive a vehicle Take it over from the entrance box accordingly and after parking it accordingly  pick up this vehicle from another storage box and put it in the exit box, already in the entrance box can drive up a new vehicle and wait for it to be picked up.

The overall advantages of the new parking system are as follows:

That drive into the parking garage in the parking box with motor vehicles from the Transport units are taken over and in a corresponding storage box be parked, and that the motor vehicles from the transport units from one corresponding storage box are transferred to an exit box and can be moved out of it. That this Motor vehicle in any rotational position aligned in a row appropriately oriented storage box can be parked.

You can drive directly to a storage space by car, which is why no pre-zone necessary. The driver can move forward out of the parking tower extend. There are no disabilities due to separate entry and exit stations Given storage or outsourcing. The system can have up to four single or four Show removal stations, but at most as many as parking box towers available. The entry and exit stations are similar to the rack spaces executed and therefore cause no great additional costs. The gratings of the Parking boxes are only attached to a cross member and with a spacer. By this simple principle, the cost of a parking box is extremely low. To a car It can be lifted with little constructive and material effort necessary, the center of gravity of the car as close as possible to the load handler to position. This is achieved in the invention by a transverse recording. On additional advantage of the transverse bearing over a longitudinal bearing is that that the way of the lice pick-up to the car is shorter and therefore the Access times can be shortened. By eliminating transportation aids such as Pallets or channels or the like, the transport routes around them are omitted to put them back in their place. To make a parking system susceptible to interference minimize, it should be ensured that as few different interlock mechanical components around an input or Carry out the outsourcing process. An important factor in a mechanical Parking garage is the energy required for a storage process. By the use of a counterweight is based on the present invention reduced to a minimum. An additional advantage is that due to the  Use of a counterweight the lifting drive and the gearbox smaller or can be dimensioned weaker than would be the case without what the Reduces costs.

In order to keep the noise level of a lifting process low advantageously used hoisting ropes. The speed monitoring of the The lifting box is operated by a centrifugal brake on the roof of the lifting box.

Another advantage of the system according to the invention is the low cost factor and the low assembly times, which is achieved by a compact design.

The system is characterized by the fact that with 3 drives that are on together the lifting conveyor box, can achieve the advantages mentioned above. The for Well-known mechanical parking garages are by their complexity prone to failure, cost-intensive and have high access times.

In the following, the invention will be explained using only one embodiment illustrative drawing explained in more detail.

Fig. 26 is a side view of the arrangement of Fig. 25,

Fig. 27- Fig. 29, the same operational conditions, such as with reference to FIGS. 22-24 illustrated.

The parking system according to FIGS. 1 and 2 consists essentially of a building which can be arranged above or below ground.

Between correspondingly arranged support pillars 1 there is a lifting and lifting device 12 which can be raised and lowered and which in the exemplary embodiment shown can be raised and lowered by means of ropes 61 .

However, the invention is not limited to the lifting drive of the lifting conveyor device 12 by means of ropes and rope drive. All lifting drives can be considered for such a lifting conveyor device, in particular also mechanical spindles, hydraulic piston / cylinder arrangements, chain drives and the like.

However, the use of rope drives is advantageous because this is a very is inexpensive and simple solution.

Starting from the support pillars 1 , cross members 2 are provided, on which the deflection pulleys 24 , 25 , 27 carry the cables 64 by means of brackets.

The rope is driven by a motor 28 which drives the rope via a corresponding drive drum. There is also a rope monitor 29 which is equipped with a centrifugal brake 23 .

Storage boxes 3-8 arranged one above the other and next to one another are arranged in the frame-like housing of the parking garage.

In the plan view according to FIG. 2 it can be seen that these are arranged evenly distributed around the circumference around the lifting conveyor 12 .

There are further storage boxes 3 a, 4 a, 5 a, which are opposite to the storage boxes 3 , 4 , 5 mentioned above.

There are entry and exit boxes 9 , 10 at the level of the entrance and exit to the parking system. For example, an entry box 9 is formed on the left side, while an exit box 10 is provided on the right side. Additional entry and exit boxes can be arranged to increase the capacity during storage and retrieval.

The lifting conveyor 12 essentially consists of a ceiling frame 13 which has corresponding frame-like side walls, which in turn are connected to a floor frame 14 . So it is a box-shaped structure, so that the lifting conveyor 12 is driven as an approximately frame-like box in a vertical conveyor shaft 11 in the area between the side walls 1 can be raised and lowered.

The entire cable drive consisting of the motor 28 , the cable monitor 29 and the centrifugal brake 23 is thus attached to the ceiling frame 13 of the lifting conveyor 12 .

The displacement device 17 in the lifting conveyor 12 essentially (see also FIGS . 16-21) consists of a displacement fork 16 which is displaceably guided and driven in the arrow direction 18 and in the opposite direction to a displacement guide, the entire displacement device on a turntable 15 rests, which is rotatable about a vertical with the longitudinal axis.

The motor vehicle 19 entering the entry boxes 9 thus stands on a storage rack which is supported and reinforced by a cross member 35 .

The vehicle travels into the entry box 9 in the direction of the arrow 30 .

Fig. 2 shows that further entry boxes 9 a, 9 b are arranged on the entry and exit level at an angle of 90 °, so that these entry boxes 9 a, 9 b can either be used for entering or exiting or also as normal parking spaces.

Fig. 1 shows, moreover, that in certain Abstellboxen now motor vehicles 20, 21 are turned off 22nd The motor vehicle 20 standing on a storage rack 33 in the exit box 10 can thus extend in the direction of the arrow 32 .

It is therefore important that the storage boxes are arranged at an angle of approximately 90 ° to each other around the rotating circle 31 of the turntable 15 , so that, due to the rotation of the shift fork, the vehicle accommodated in the drive-in box 9 is moved into any parking position 9 a, 9 b, 10 can be turned off.

This results in the essential advantages of the invention, because from Fig. 2 it can be seen that to reach under the vehicle parked in the transverse direction, the length of the shift fork 16 only has to be chosen relatively short, because the vehicle only has to be undercut on the broad side and not from its long side, which would require telescopic sliding forks, which can be omitted here.

This results in the further advantages mentioned above, namely a quick one Turnover speed due to short displacement distances.

Fig. 2 shows, moreover, that the outwardly discharging storage grates 33 are underpinned and supported by corresponding, vertically arranged support pillars 34 .

The exit box now again consists of a ceiling wall and adjoining side walls 37 , as does the entry box 9 .

The storage racks 33 are each gripped approximately centrally by a continuous cross member 35 , which is connected laterally via side members 36 , which in turn are attached to the side walls 1 .

In Fig. 3 it is shown that, starting from Fig. 2, the shift fork 16 was first shifted in the direction of arrow 18 via the shift guide 17 , so that the shift fork 16 is now passed under the rack 33 in the drive-in box 9 .

Fig. 4 shows that the tines of the shift fork 16 are received in the space between the tines of the storage rack 33 . Here, the slide of the shift fork 16 was shifted in the area of the slide guide 38 of the shifting device 17 , as shown in FIG. 4.

The entire lifting conveyor 12 is now in the direction of arrow 39 by a small displacement of z. B. 8-10 cm raised so that the surface of the shift fork 16 rises above the surface of the storage rack 33 and the vehicle 19 now rests on the shift fork 16 and is slightly lifted with this.

The shift fork 16 is then retracted into the lifting conveyor 12 in the direction of the arrow 18 ′ and the vehicle 19 is thus in the lifting conveyor 12 .

This is shown in plan view in FIG. 7.

By means of a corresponding rotary drive of the turntable 15 according to FIG. 8, the latter can, for example, rotate the shift fork horizontally by 180 °, so that the vehicle comes exactly opposite to an adjacent storage box, as shown in FIG. 9. The rotating device is equipped so that it does not have a stop and can therefore be rotated into the corresponding position in both possible directions of rotation.

In this rotational position, the lifting conveyor is now raised, as shown in FIG. 10.

It goes without saying that the rotation on the turntable 15 can also take place during the lifting drive of the lifting conveyor according to FIG. 10 and the vehicle can be parked in a correspondingly oriented storage box in any rotational position oriented according to rows of shelves.

The Hubfördergerät now travels in FIG. 10, a corresponding box-shaped parking 4 a and moves the shift fork 16 in the direction of arrow 18 ', so that the vehicle 19 reaches the position of FIG. 11 and 12.

By slightly lowering the lifting conveyor 12 in the direction of the arrow 39 ', the shift fork 16 is now lowered below the level of the storage rack 33 , so that the vehicle 19 is placed on the storage rack 33 and the shift fork 16 is thus released again.

The parking process is thus ended and, according to FIGS . 14 and 15, the sliding fork 16 moves again in the direction of arrow 18 into the lifting conveyor 12 and is now ready to pick up another vehicle either from an entry box or a parking box and then in a corresponding box as already described to deposit again.

If a vehicle to be parked, then takes the same procedure as described in reverse order, ie, a vehicle recorded on the shift fork 16 is engaged with the Hubfördergerät 12 in juxtaposition to the Ausfahrbox 10 and the vehicle mounted there on the located there drip tray 33 . It can then leave the exit box 10 in the direction of the arrow 32 .

In Figs. 16 to 21, further details of construction of the Hubfördergerätes in conjunction with a parking are illustrated.

First of all, it can be seen in FIG. 16 that the slide guide 38 is two profiles which are arranged parallel to one another and at a mutual distance from one another, between which a slide 45 is displaceably driven.

The carriage 45 is preferably displaced in the region of the carriage guide 38 via an electric motor which drives the carriage 45 via a chain drive.

The displacement device 17 also consists of a support yoke 44 fastened to the slide 45 , which is connected to the slide by corresponding stiffening plates, the displacement fork 16 being arranged on one side of this support yoke, which consists of individual grate bars which are formed parallel to one another and take a mutual distance from one another (see Fig. 20).

Referring to FIG. 20, the grate bars 56 are about engage beneath the center of a cross beam 43 with the grate bars are additionally reinforced by an underlying spacer profile 42 46 approximately over half the length of the grate rods of the yoke 44 to the cross member 43. This cross member 43 is arranged in such a way that it connects at least some of the grate bars 46 to one another and thus additionally takes on a static function by means of which the grate bars can be dimensioned weaker.

So it is a very cheap, rigid construction, which due to the relatively short grate length of the grate bars of z. Ex. 2 m is very rigid and can be positioned precisely in a specific position due to the short length with respect to a rotation of the turntable 15 .

Thus, the ends 47 of the grate bars 46 can be inserted very precisely into the spaces 53 of the opposite grate bars 56 without the ends 47 colliding with the ends 55 during the running-in process.

The pressure of a tire 41 resting on the grate bar 46 is thus introduced via the grate bar and a relatively short length onto the cross member 43 and is transmitted from there via the grate bars and the spacing profiles 42 underneath to the support yoke 44 .

When recording of a vehicle 19 of the drip tray 33 to the shift fork 16 as shown in FIG. 16 is the upper edge 48 of the shift fork 16 below the upper edge 49 of the Abstellrostes 33.

It can therefore move the sliding fork 16 in the direction of arrow 18 in the storage rack 33 , as shown in Fig. 17.

Only when the lifting conveyor 12 has carried out a slight, vertical lifting movement 50 upwards does the upper edge 48 pass over the upper edge 49 and the tire 41 of the vehicle 19 thus stands on the grate bars 46 of the displacement fork 16 .

The displacement device 17 can thus be moved back in the direction of the arrow 18 ′ according to FIG. 19 and the vehicle now rests on the displacement fork 16 . These transfer processes are shown again in FIGS. 20 and 21.

In an analogous manner, each storage grate 33 has a side support 51 on the side, which receives all grate bars 56 . In this storage grate there is an approximately central cross member 35 which is supported by the vertical support pillars 34 .

There, the grate bars 56 shown can also be underpinned by spacer profiles (not shown) and additionally supported.

During the import process, the grate bars 46 and 56 , which are assigned to one another, come into mutual engagement because the respective intermediate spaces 53 , 54 overlap.

After completion of the extension process the ends 47 of the grate bars 46 form a short distance from the abstellseitig arranged side beams of the grid shelves 33rd

The same applies to the ends 55 of the grate bars 56 , which form a short distance from the yokes 44 on the shift fork of the shift fork 16 .

Figs. 22-24 show a recording process of the motor vehicle 19 in a box-shaped parking.

In this case, the storage grate 33 is formed approximately in two parts, the upper part being formed by a plurality of grate bars 56 , each of which is gripped and supported by a spacer profile 52 .

The tires 41 of the motor vehicle rest on the upper edges 49 of these grate bars 56 .

It will now be shown in FIG. Retracted, the shift fork 16 23, which is formed in two parts also in the manner previously described, wherein here also the cross member 43 and the overlying spacer profile is seen 42, which supports the grate rods 46.

The upper edge 48 of the grate bars is arranged below the upper edge 49 of the grate bars 56 .

Only with a lifting movement of the shift fork 16 , vertically upward, does the upper edge 48 of the shift fork 16 pass over the upper edge 49 of the grate bars 56 , so that the tires of the vehicle 19 now rest on the shift fork 16 , as shown in FIG. 24.

FIG. 25 shows an exemplary embodiment of a sliding fork which is modified compared to FIG. 16 and has a different support.

Here, the grate bars 46 according to FIG. 26 are gripped by a cross member 59 , each grate bar 46 being supported on a spacer profile 42 , which in turn is connected to the cross member 59 .

On the cross member 59 , side members 58 are attached laterally and at right angles, which in turn are connected to the support yoke 44 . The sliding frame 57 formed in this way thus has free grate bars 46 on the front and rear, so that a distance 60 to the support yoke 44 is formed on the rear side of the grate bars.

In the embodiment according to Figs. 16 to 20, the reaction force is introduced from the motor vehicle on the grate bars in the formed as a girder cross member 43, while in the present embodiment according to Figs. 25 and 26, the bearing force directly to that of the grate bar 46 in the cross member 59 and of is introduced into the support yoke 44 via the side members 58 .

Figs. 27 to 29 in turn show a recording process of a motor vehicle 19 in a box-shaped parking purpose of the acquisition on the shift fork, in which case the sliding frame 57 of FIG. 25 and 26 is used.

Otherwise, the same explanations apply as were given with reference to FIGS. 22-24.
