Description

The invention relates to a system for recording, temporary Storage and delivery of movable objects, in particular unmanned, movable vehicles, according to the Preamble of claim 1.

In buildings that house a variety of motor vehicles, in particular passenger vehicles are determined, such as B. in car parks and large garages there is a need as many vehicles as possible on the available Space to accommodate. If the pitches and the access roads are designed so that each parking space is individual can be approached, remains a large part of the total area unused because you get to the one of a parking space occupied area again an approximately equal area for the driveway and the space for maneuvering got to. Half of the available space remains unused.

To save space, facilities have already been implemented in which the vehicles are on movable parking spaces in the manner of a paternoster elevator or one arranged horizontally Conveyor belt can be turned off, as required only one of the numerous parking spaces in front of the and exit is brought (see research society for Roads and Traffic, Road Design Working Group, Information on the use of mechanical parking systems ", edition 1995). Such a system requires complex drive mechanisms with those with every entry and exit of a vehicle with all the parking spaces on it vehicles must be moved.

A known system is also less complex, where the shelves are fixed next to and / or one above the other are arranged and one or more transport platforms are provided that accommodate the vehicle and up to one Bring space on which it is then transferred. To the The vehicle is extended with the transport platform to the Brought exit. Here, the vehicle with its drive from the driver from the transport platform to the footprint be translated.

In a mechanical parking facility of the generic type Type are the parking spaces along a helix in radial Direction arranged. In the remaining cylindrical A transport device called a tender travels through the cavity on one that is also bent according to a helix Rail, at least one tender arm being provided, which is supported on the rail by means of two running wheels. A motor vehicle to be parked can move upwards on the arm or transported downwards by the tender rotates about its own axis for lifting or lowering, so that by means of the arm a motor vehicle from an entry platform to a free parking space or from this to an exit platform can be moved.

It is known from the prior art, according to US 34 19 162, a parking garage to be provided with a central conveyor shaft, at the edge of which a helical shape guided rail is arranged. Around the helical rail are Parking spaces are provided for parking vehicles. The vehicles are over a central conveyor, which is guided on the helical rail, brought to the pitches. The conveyor is for receiving each suitable for a vehicle and comprises a rigid gripper device which is guided along a conveyor chain. To transport a vehicle, the Gripper device placed under the tires of a vehicle. Subsequently the gripper is tilted by the control of the conveyor chain and the two The front wheels of the vehicle are raised automatically.

Furthermore, it is known from the generic DE 16 84 721 to have a parking garage equipped with a helical rail around which a large number of parking spaces are arranged. In the middle of the parking garage is a conveyor with one Translation device equipped, the vehicles from a drive-in platform can accommodate and transfer to a variety of parking spaces. The The translating device is mounted on several support arms of the tender and has a lengthwise between the wheels of the standing on a platform Movable frame device on the vehicle. This framework is driven to translate a vehicle under the vehicle in order to then move four rigid gripper arms under the front wheels. The front wheels are then raised and up by the translator brought the conveyor.

The invention is based on the object, a generic system to further develop that the implementation of motor vehicles with brakes Front and / or rear wheels are carried out safely and quickly, and the transfer mechanism is structurally simple. Furthermore, the plant with regard to their operational safety, stability and wear resistance, in particular even in winter, the harsh operating conditions that occur in everyday life do justice to a high degree.

This object is achieved by the features specified in claim 1 solved.

It is now by means of the translation device according to the invention possible, the vehicle parked on an entry platform record, move to the tender arm and by means of the Tenderarms, which is curved along the helical Rail moved up or down, in front of one To transport a parking box to the platform Put down the platform of the parking box or in the opposite case when picking up a parked vehicle from the parking space to pull on the tender arm and to an extension platform passed from where it can be driven away by the driver can.

The translation device advantageously has one lengthways between the wheels of the on a platform stationary vehicle movable frame device which is at least four right angles to the area of Cantilevered support arms are arranged. At least two of these support arms are according to the invention from one in Direction of the frame device in the position right-angled cantilevered position in which it under pressure on the lower area of the respective vehicle wheel fit and lift it off the stand. Essentially is the framework of two in itself Formed longitudinal beams of the longitudinal arm extending longitudinal beams, those in the area of the inner, to the tender central axis pointing and the outer end facing the tender support arm are connected to each other by cross beams. During the front wheels of a motor vehicle four assigned support arms are provided, of which the two facing the tender axis Support arms rigid in the area of the inner ends on the side members arranged and the other two support arms advantageous are pivotable against the back of the front wheels, to press them against the rigidly raised support arms and to be lifted are the two rear wheels of the motor vehicle only two diametrically arranged to the wheel axis of the vehicle Assigned support arms. The formation of the device by means of of the four front support arms described above is just in case expedient and sufficient, in which the rear wheels of the Motor vehicle on the corresponding tread of the tender arm or roll on the parking space floors. It means that the rear wheels of the motor vehicle to be moved are not braked are. However, in the case where the rear wheels are braked, this z. B. in connection with automatic Gears and anti-theft devices may be the case is the device according to the invention with two more Rear wheels of the vehicle assigned pivotable support arms equipped, one against the front of one Rear wheel and the other against the back of the other Rear wheel is pivotable. In this way the translation device advantageously all four wheels of the vehicle detected and jacked up so that the vehicle Piggyback into or out of the box, so to speak this is transported out.

To the translation device according to the invention to different Being able to adjust wheelbases is advantageous provided that the distance between the rear wheels of the Assigned to the vehicle and assigned to the front wheels of the vehicle Bracket is adjustable, this setting mechanically using a screw spindle or hydraulically using a piston / cylinder arrangement or electric motor can be done with rack. By arranging a pivoting support arm in front of one rear wheel and the other Raise the swiveling support arm behind the other rear wheel when the support arms hit the rear wheel tires arising horizontal forces on each other. This system owns a system in which, for example Strike both support arms against the front of the rear tire would have the advantage of avoiding the danger that the two front wheels from their horizontal forces Supports are pulled out.

To reduce the frictional forces between the support arms and vehicle wheels are on the support arms in the area with the long sides coming into contact with the vehicle wheels rotatably mounted rollers are provided. The framework itself is with rollers on the top of two on the edge raceways running in the longitudinal direction of the tender arm up to can be moved to a corresponding platform. It is also provided that the raceways have side edges, against which the support arms that are on the top of the raceways are supported by rollers, by means of a vertical Start the rotating guide rollers. To this Way, the translation device according to the invention in its Longitudinal movement between the lateral edges of the raceways guided.

The tender advantageously has four tender arms, each with a transport device, e.g. a toothed belt drive, to drive the frame device of the translation device are equipped. Of course, there are also other drive systems applicable, e.g. a chain drive or hydraulic drive. The toothed belt drive can be an endless toothed belt have the one at the inner or outer end of the Tender supporting arm with horizontal toothed pulley is. The vertical arrangement of the timing belt ensures that no dirt can accumulate on the timing belt possibly premature destruction of the drive device could lead. The translation device is advantageous with its rear end with the toothed belt, for example connected via clamp connector and can therefore cantilevered from the tender arm according to the direction of rotation of the toothed disc pushed a parking box or out of the parking box back onto the Tender arm to be withdrawn. The translation device when picking up a parked motor vehicle from a Parking box moved from the tender arm towards the parking box until the two rigid support arms are approximately at the level of the Front wheels of the car parked on the entry platform stand. The two swivel arms are up to this position is still at rest, d. H. they are parallel to the two side members of the frame device Translator. This allows them to switch between the two Front wheels are pushed through. As soon as they stare Support arms are in their end position and the translation device stops, the two swiveling support arms are over Advantageously two hydraulic presses at 90 ° in each rigid support arm pivoted parallel position. In the The swiveling support arm lies down in the final phase of the swivel movement to the rear of the front wheel tire and presses the front wheel to the parallel during the remaining movement End position upwards. This will raise the two front wheels from the floor of the parking space.

Is preferably between the translation device and the Timing belt arranged a drawbar through which the vehicle can be pushed further out in the radial direction. If the vehicle is in the entry or exit box for exiting or Passengers boarding further than in the parking boxes is pushed outside, there is a larger lateral distance on the vehicle to the neighboring boxes. this makes possible Comfortable getting in and out of the vehicle for the occupants without the doors being opened by the neighboring ones Walls are narrowed.

To the drawbar when moving the translator The drawbar must be secured against torsion and / or torsion preferably formed from a torsionally stable square bar and has a guide device received between sliding elements. The translator can, according to a certain Entry area of guide rollers on the support arms are attached to the side edges of a parking space be performed. To achieve the highest possible degree of volume filling to maintain the system, the individual overlap Parking spaces in their radially inner area, so that due the cramped space there no side upstands are available at the parking spaces and therefore none Guide the translation device through the guide rollers the support arms is possible. Guaranteed in this area the drawbar guide a safe and precise guidance of the Translator.

The two longitudinal beams of the translation device are advantageous Way within the gauge of the load-transmitting Track rollers arranged and not approximately in the track width the load-transmitting wheels. This can result in a low Construction of the translation device can be achieved and a very simple construction, since the loads are directly from the Carrier arms rollers are introduced into the tread and the translator i.w. just absorb their own weight and has to derive.

One advantage of the four-wheel translator is below also in that the loads from the weight of the Motor vehicle regardless of the track width of the motor vehicle always in the gauge of the six support arms of the Translation device arranged rollers on the platform or the careers are transferred. In one execution the translation device, in which the motor vehicle on the two rear wheels are rolling and only with the front wheels is jacked up, the place of the load transfer depends on the different track gauges of the motor vehicle.

The pivotable ones assigned to the rear wheels of a motor vehicle Support arms are advantageously mounted on a slide, which in turn by means of bearings on the side members is led. Using this sled and a suitable one Drive can be the distance between the front and rear Change support arms so that the translator on different wheelbases of different motor vehicles is customizable. The bearings with which the sled is on the side members are guided, are advantageous PTFE plain bearings. In addition, the sled has on his two long side casters with which he is in his rest position after swiveling the support arms on the raceways of the tender arm or the platform is supported.

So that the support arms when swiveling back in their longitudinal direction the longitudinal beam running rest positions compared to the Raceways of the tender arm or the surface of the platform are guided without contact, it is advantageous if they when swiveling in the longitudinal direction along the side members on an inclined plane.

The tender arms can be rotated accordingly of the tender are aligned with the platforms, which side by side and in the radial direction around the Tenders are arranged around. One or more can be used Entry and exit platforms next to parking box platforms be provided, the same structure with each other exhibit. It is advantageously provided that each platform extends from a maximum vehicle length extending sheet metal with at least lateral upstands is formed, which on a frame substructure lies on. This frame substructure has at least two individual loads attacking the mobile device receiving longitudinal beams, which in turn on at least two Cross beams are supported, which support the loads in the building transfer. The inner (to the tender axis pointing) platform end via a cross member on consoles be supported on the tender track.

The sheet is advantageously made from de-icing salt solutions made of corrosion-resistant, wear-resistant material, especially made of ferritic, chrome-alloy steel. This material has a high wear resistance, is corrosion-inhibiting, especially against weak salt solutions resistant to one at the same time because of the low Nickel content high wear resistance. The steel has a significantly lower one than austenitic steels Coefficient of thermal expansion, so that when welding austenitic steels are not subject to high heat distortion is to be expected. The price is also around 50% of the price of austenitic chrome-nickel steels. Is preferred a ferritic chrome alloy steel with 10.5 - 12.5% Cr at only 0.3 - 1.0% Ni.

In addition to its covering function, the sheet also has certain supporting functions take over.

So it takes up the weight of the translator, the over the on the two longitudinal beams of the translation device arranged rollers in the unstiffened part of the cover plate is transmitted. Furthermore, the brakes or Starting the tender on the support brackets of the tender rail generated horizontal forces to the inside of the Cantilevered platform transmitted over the Cover plate acting as a push field is derived into the supports Need to become. Finally, because of the different Gauges of the parked motor vehicles the rear or Front wheels of the motor vehicle stiffening to the side of the two Platform side rails lie. For local bracing To avoid the cover plate in this area was over a finite element study demonstrated that a 4 mm strong sheet metal due to plate and mainly membrane effect these cars can absorb wheel loads. To absorb normal forces due to the membrane effect on the two longitudinal edges of the floor plate created by bending up rigid edge beams will. These backsplashes are more advantageous Way required at the same time to drain sideways to prevent the water running off the motor vehicles.

According to a further advantageous feature of an embodiment the sheet on the longitudinal or cross members only through Clamping forces held. Furthermore, between the sheet and the Substructure advantageously a shock absorbing Layer of wear-resistant elastic material in particular Rubber provided. This layer prevents you direct contact between the cover plate and the longitudinal or cross beams. The elastic above the side members Material, e.g. B. in the form of rubber strips can improve the load transfer from the Rollers of the swiveling support arms of the translation device and prevents one by relative movement of the sheet possible wear on the side members.

To fix the front wheels of a motor vehicle on Flat iron attached to the top, especially screwed on to be a possibly twisty To avoid welding. The clamps for fastening the sheet on the brackets and the flat iron for the front wheels are screwed onto threaded bolts. By using bolted-on bolts Through holes avoided, through which possible Water could drip onto the cars parked underneath.

All platforms are advantageously on the outside of the building inclined by about 2%. Because of this gradient dripping water can be drained to the outside and drips down to an annular channel in the base of the building. Because of the only corrosion-inhibiting effect of the material used must be avoided that water containing de-icing salt longer Time to stand on the surface of the floor plate can.

Because the tender arms are only temporarily assigned to certain platforms are, it must be provided that at least on the inside the entry and exit platform or platforms collapsible personal protection devices are provided, which close the platform area from the tender area, as long as there are people in the platform area. Otherwise, the parking box platforms are such Do not protect the facility as it is in the parking area no people stop.

It should be borne in mind that with all mechanical parking systems the access time or the hourly capacity of the Transport system for economy and acceptance of the parking system is a decisive factor. In parking garages with linear parking systems, in which the horizontal and the Vertical movement in succession is the access time very long, so that the delivery rate is low. At a Parking garage equipped with the parking system according to the invention however, the access time can be reduced to two minutes each Vehicle can be significantly reduced. Here the lifting or the lowering movement and the rotating movement of the tender be carried out simultaneously. Such short access times can only be achieved by connecting different ones in parallel Transport processes and high transport speeds on the tender or when transporting with the translation device.

To achieve an optimal conveying performance of the transport system is advantageously provided that the tender has four support arms offset from one another by 90 ° and that four entry platforms each cross the tender arms assigned. The full transport capacity of the four-armed Tenders can only be used sufficiently if pushing the vehicles in from the entry platforms the four tender arms can run simultaneously and if possible also the subsequent translation from the tender arm the parking space takes place simultaneously. That means because of arrangement of the tender arms offset by 90 ° also one Corresponding arrangement of the entry platforms offset by 90 ° and Z. B. offset by 45 ° relative to the entry boxes Arrangement of the exit platforms. In each of If possible, the motor vehicles will become floors of the parking system parked in parking spaces offset by 90 °. After that some time due to the random parking of the vehicles in the individual floors this 90 ° arrangement of still free parking spaces must be lost using a computer program at least two still free offset by 90 ° Parking spaces are selected so that at least two parking processes can run simultaneously.

Is the crosswise arrangement described above for space reasons the entry or exit platforms not possible, so are advantageously at least three side by side Entry platforms combined with three by 90 ° each exit platforms arranged offset to the entry platform.

The tender then only fetches three vehicles from their parking spaces off, so leave one arm free. This free arm is in front drove an entry platform that was offset by 90 ° the second tender arm then stands in front of an extension platform. In order to a vehicle can be pushed onto the free tender arm at the same time be while another vehicle is loaded Tender arm is pushed into the extension platform. Subsequently the tender continues through an angle of 90 ° ± dz, so that on the just cleared arm on the entry platform a vehicle can be charged and at the same time from the next loaded arm to a vehicle next exit platform can be pushed off.

Advantageously, the speed of movement is Translation device controllable so that an unloaded Translator is faster to move than a loaded Translator. Since the extension of the rear part of the Transfer device for jacking up the rear wheels Motor vehicle is a time-consuming process that always can be omitted if the rear wheels are not braked the driver is asked in all cases when parking, to release the handbrake. Only for vehicles with automatic transmission can block the rear wheels cannot be solved during parking.

Now with a vehicle standing on an entry platform to check whether the rear wheels are locked is in advantageously provided that the extension of the slide part the translation device and the swiveling of the Support arms for the rear wheels of a vehicle depending from a current consumption exceeding a predetermined limit value of the drive motor of the toothed belt drive of the transmission device he follows. The procedure is as follows:

The translation device includes with the two pairs of brackets the two front wheels of the vehicle and lifts during the Swing out the support arms on the two front wheels. Subsequently the translating device moves in the direction of the tender arm. The current consumption of the drive motor measured as it is a measure of the driving resistance found is. Because the rolling resistance number in a car tire only approx. 1.5% of the tire load is at least approx 50% of the tire load with sliding friction when grinding the blocked Rear wheels on the pad is the sliding resistance the lightest vehicle with braked rear wheels significantly higher than that of the heaviest possible vehicle with free-running rear wheels. Regardless of the vehicle weight can therefore from the current consumption of the drive motor of the translator are determined whether the rear wheels are blocked or not. Only in the relatively rare If the rear wheels are blocked, the rear part of the Translator extended. This measure succeeds it advantageously, the output per hour almost to double.

In an advantageous embodiment of the invention are means provided the position of the motor vehicle on the Secure the tender or the translator against moving. This prevents that which is stored on the tender Motor vehicle due to centrifugal forces during rotation of the tender jump out of the holder of the translator can. This is particularly problematic when the wheels only added between the two front swivel arms and the vehicle is not held by the rear arms becomes. It must also be taken into account that the centrifugal force linear from the mass of the vehicle and quadratic from the Speed of the center of gravity is dependent. At large vehicles with a fully loaded luggage compartment Center of gravity radially outwards in the area higher Rotational speeds. The centrifugal forces that occur can preferably be picked up by two devices will. The first device is on the location of the front tires on the front arms of the translator and the second device behind the rear bumper. Because the bumper was limited Can absorb forces using the spring action the vehicle tire distributes the centrifugal force achieve on the front and rear device.

The device located on the rear bumper is preferably provided for the special case that the toothed belt, which holds the translator in the radial direction, tears. Then the absorption of the centrifugal force alone over the barrier on the rear bumper. Under these circumstances, damage to the bumper can occur arise, damage to the entire vehicle by moving the tender is avoided.

Basically, when turning the tender, the safe one Recording of the vehicle on the tender can be guaranteed. A safety factor must also be taken into account in the event that, for example, the trunk is loaded, the front axle is relieved and so the holding forces on the front swivel arms can be reduced.

The said agents preferably have at least one pivotable bracket on the radially outer side one wheel of the two front wheels of the motor vehicle attacks. This bracket can be on the tender arm or on the two be arranged front swivel arms. By the motor Swiveling the bracket to the wheel of the motor vehicle is the motor vehicle on the tender against moving as a result secured by centrifugal forces. The swivel drive motor can be controlled so that it reaches the pre-settable The pressing force of the bracket against the tire switches off. Furthermore, it is alternatively possible to use one lever each those attacking the rear of the front wheels Swivel arms of the translator to provide the vehicle secures against displacement due to centrifugal forces. Here the lever can be short and hard sprung to accommodate size differences of the tire diameter for different vehicle types to be able to compensate.

In an advantageous embodiment, the securing means have a flap on the translator that is attached to the The rear of the vehicle can be folded against its bumper, the position of the motor vehicle on the translator to secure.

The plant shown in Figure 1 forms an underground arranged parking garage, in its basic structure as a hollow cylinder is designed. In the above-ground part is at 1 the entrance and at 2 the exit. Inside the A large number of parking spaces 3 are accommodated in the hollow cylinder, which are aligned radially with their longitudinal extent are and with their radially outer ends to the inner wall of the Adjacent hollow cylinder. Pitches 3 are along one Helix arranged so that they from the first to last or from the top to the bottom parking space without Break next to each other. On their radially inner Side they are connected by a rail 4, accordingly also helical runs.

In the cylindrical not occupied by the parking spaces 3 Inside there is a so-called tender 5 four support arms 6. Each of the tender's support arms is above each two wheels 7 supported on the rail 4. On the four arms of the tender 5 can collectively four to be parked Motor vehicles 8 are transported upwards or downwards. The tender 5 rotates during the lifting or lowering process on its own axis, so that each of the four arms has one each free parking space or an entry or exit platform can start.

The translation device 9 according to the invention essentially has one in the longitudinal direction between the front wheels 10 and the rear wheels 11 of a motor vehicle 8 movable frame device 12, four of which are at right angles to the Area of the front wheels 10 projecting support arms 13, 14 for the front wheels 10 and support arms 15, 16 for the rear wheels 11 are provided.

The frame device 12 has two in the longitudinal direction of the arm 6 extending longitudinal beams 17, which are in the area its inner, facing the central axis of the tender and the outer, to the end of the tender bearing arm with a cross member 18, 19 are interconnected. The side members are z. B. 5.60 m long and consist of RRO profiles. The inner, for Tender center axis facing cross member 18 is by a top and widened sheet 20 placed on the longitudinal beams below. The outer crossbeam lying in the direction of the tender arm 19 consists of a transverse rectangular tube. The support arms 13 are rigidly mounted on the inner end of the frame device 12, while the support arms 14 by means of two hydraulic Piston 90 ° in a horizontal plane around a pivot point 21 can be rotated. The support arms are approximately in the Provided with rollers 22 in the middle of their longitudinal extent, by means of which the support arm is on the tread of the tender arm 6 can support.

There are also at the outer ends of the support arms 13, 14, 15, 16 guide rollers 24 are attached, by means of which the vehicle 8 laterally on upstands 25 of the tread 23 or 26 one Parking space 3 is guided laterally (see Fig. 7 and 8).

The rear support arms 15, 16 are on a slide 27 pivoted, which in turn with the help of PTFE plain bearings 28 (see FIGS. 5 and 6) on the longitudinal beams 17th in the vertical direction and with the help of support rollers 29 in is supported in the horizontal direction on the longitudinal beams 17. The Side members and the sled are made with the help of wheels 30 movable on the tread 23 when the carriage is unloaded is, and the support arms 15 and 16 are pivoted. The pivoting movement of the support arms can be done with the help of hydraulic cylinders 31 done. When swiveling in the respective Support arm 14, 15, 16 moved along an inclined plane, so that the roller 32 is lifted from the tread 23.

The adjustment of the distance between the front arms 13, 14 and the rear support arms 15, 16 takes place via a Adjustment of the slide in the direction of arrow 33 with Help of the hydraulic cylinder 34.

On each of the four tender arms 6 is the for the longitudinal movement Frame device 12 is a transport device, in particular a toothed belt drive 35 is provided. The toothed belt drive 35 has an endless toothed belt 36, which on each one inner or outer end of the tender support arm 6 mounted horizontal Toothed washer 37, 38 is guided. The translator is with the inner end via a clamp connector 39 connected to the toothed belt 36 and can therefore depending on Direction of rotation of the driven toothed discs 37, 38 from the tender arm cantilevered into a parking box or out of the Parking box can be pulled back onto the tender arm. At the Picking up a parked motor vehicle 8 from a parking box 3 the translator 9 from the tender arm 6 so far in Moved towards the parking box until the two rigid support arms 13 stand approximately at the level of the front edge of the front wheels 10. The two pivotable support arms 14 are up to this position still in its rest position, d. H. they lay parallel to the two longitudinal beams 17. This allows them are pushed between the two front wheels 10.

As soon as the rigid support arms 13 are in their end position and the translator 9 stops, the two pivotable Support arms 14 through the hydraulic cylinders 31 through 90 ° pivoted into a position parallel to the rigid support arms 13. In the final phase of the swivel movement, the lie down Swivel arms 14 on the rear of the front wheels 10 and press the front wheels up during the remaining swing to the parallel end position upwards. This will raise the two Front wheels 10 from the floor panel of the parking box 3.

The translation device 9 is now via the toothed belt drive 35 pulled back towards the center of the tender and hauls 11 cars rolling on its two rear wheels with it on the tender arm. The tender is now in this position 5 or the relevant tender arm 6 to the extension platform driven, the translator 9 then shifts that Motor vehicle 8 on its two freely rolling rear wheels 11 so to speak, in the reverse direction of travel into the exit box.
