Description

PARKHOUSE ELEVATOR FOR VEHICLES

The present invention relates to a lift for vehicles in a multi-storey car park. The aim is to safely and quickly lift and lower the vehicles and also to turn the lift platform. With WO2006 / 039830 an automatic parking system has become known, which operates with a central elevator, from which the vehicles are pushed radially to around the central elevator shaft arranged parking levels. The elevator proposed there is intended for a single vehicle. The entire elevator construction rotates around the vertical axis so that the vehicles can be pushed out in different directions on the parking levels. The vehicles to be parked are measured beforehand, for example with the aid of a scanner, in order to detect in which parking space in the parking garage the vehicle can be placed by the associated robot in such a way that the least space is needed. It has been shown that it is sufficient for this survey to know the contour of the floor plan of a car, that is, its shadow on the ground, with incident on the ground incident light radiation, and the maximum height of the vehicle. If the vehicles are parked in an optimally space-saving manner, taking into account the contour of the floor plan, an area of only 15 m ^{2 is} claimed on average for a single parking space. It succeeds parked vehicles of a maximum of 5.3m length parked side by side on an annular disc of only 8.7m outside radius. 16 vehicles with a maximum length of 5.3m can be accommodated on this ring disc. The surface area is (8.72m) ² x π = -237 m ² for 16 cars, and per car results in an area requirement of ~ 15m ² . With a parking deck height of 1.80m the space requirement for the 16 vehicles is ~ 427 m ³ , and for each car ~ 27m ² . By contrast, conventional parking garages have a multiple of space required per vehicle. The dense parking therefore allows much more vehicles to be accommodated in a particular parking garage volume, and accordingly the management of these parking lots presents logistically greater challenges to the capacity of the elevator, which must pick up, lift, turn and park the vehicles on the parking lots and vice versa.

The object of this invention is to provide for car parks with a central elevator shaft an improved elevator, with which a higher capacity can be achieved, which is simpler in construction and safe in operation, and the vehicles efficiently raise, lower and can turn. In addition, this elevator should provide increased redundancy in a parking garage compared to conventional solutions.

This object is achieved by a lift for vehicles in a parking garage with a central elevator shaft and around it arranged parking areas at different levels, each with a central, adjoining the elevator shaft circular inner edge, characterized in that two elevators are arranged in the elevator shaft which are operable independently of each other, wherein each elevator platform is supported on a traverse extending approximately diametrically across the elevator shaft and extends from there into one half of the elevator shaft, wherein the traverse mounted and guided on vertical rails outside the elevator shaft delimited by two semicircles is, wherein the support cables for the traverse platform and for the at least one counterweight outside the central elevator shaft are arranged.

Based on the figures, this elevator construction will be presented and described in more detail and the components and their function will be explained.

In Figure 1, the elevator construction is shown schematically, but only one of the two elevator platforms 1 is shown. The elevator is used for lifting and turning unmanned vehicles in a parking garage with a central, surrounded by two semicircle hoistway 13 and around it at different levels arranged parking or parking decks 14. It is here just a single annular parking floor 14 located, but are effective a plurality of such parking decks 14, each with a central hole as elevator shaft arranged one above the other, where they can also form different storey heights by being spaced differently from each other to accommodate vehicles in categories of different vehicle heights as compact as possible. A sports car needs much less floor height than a delivery van. Therefore, individual can Parkdeckgeschosse be designed on a floor height of, for example, only 1.50m, others in turn to 2.30m or higher, depending on your choice. In the central circular recess, which acts as elevator shaft 13, two elevator platforms 1 are arranged according to this specific elevator construction, which can be operated independently of each other. In FIG. 1, for the sake of simplicity, only one of these two elevator platforms arranged symmetrically to one another on either side of and beyond a diametrical line is drawn, namely that which projects from the center of the elevator shaft 13 towards the viewer. Each of these elevator platforms 1 is supported on a traverse 17 which extends approximately diametrically over the elevator shaft 13 and projects from there laterally into one half of the elevator shaft 13. The traverse 17, which belongs to the elevator platform 1, here forms a total of a rectangular structure with inner braces, a box structure or a truss structure. From the upper edge of the traverse 17 from the elevator platform 1 extends to the side of the elevator shaft 13, which is against the viewer. The other symmetrically arranged traverse and its rearwardly extending elevator platform are not shown here. So that the elevator platform 1 receives load capacity, it is supported on the struts 3 at the bottom of the cross member 17. The crossbar 17 itself extends lengthwise beyond the elevator shaft 13 and is mounted and guided at its vertically extending end edges in a respective rail 8. At the upper edge of the trusses, a force acting on the truss edge towards the elevator platform 1 acts, because of the load of the elevator platform 1 and a vehicle parked thereon, while a force acting on the lower truss edge over the struts 3 acts in the opposite direction from the lower truss edge shows (torque). These forces are transmitted by steel rollers on the rail 8, on which these steel rollers roll. Between the two rails 8, a central rail 28 may be arranged at the periphery of the elevator shaft 13, and the elevator platform is then struts on the struts 27 and stored at those by means of steel rollers. This gives the elevator platform 1 additional stability. The cross member 17 with the attached elevator platform 1 is held by the support cables 5. These are guided above the uppermost parking level 9 to a pulley 11 and then lead outwards, out of the elevator shaft 13 addition. A little further out is ever another pulley 12, around which the rope is guided down and acts as a support cable 6 for the counterweights 7. The drive motor 10 may be installed on top, or between the pulley 12 and the counterweight 7. Advantageously, a gearless outer rotor is used as a drive motor. The support cables 5,6, on both sides of the elevator shaft 13 must run quite synchronously and can be driven by a single motor with appropriate cable guide, or each of its own engine, these motors must then be exactly synchronized with each other. It is important to note that the entire support cables 6 and their drive including the counterweights 7 are located outside the elevator shaft 13, in niches 15 which extend vertically through all the parking decks 14 and in which the counterweights 7 move up and down. In the elevator shaft 13 are exclusively the trusses 17 and the side mounted on them swivel platforms 1. These two trusses 17 and platforms 1 can move up and down completely independently and the platforms 1 can also be pivoted independently. For this purpose, they each rest on a turntable 2, which can be driven and on which the elevator platform 1 is rotatable on both sides by 180 ° into this side of the elevator shaft about the vertical axis, into which it projects from the tranverse 17. It is only to be considered that the platforms 1 may only cross when aligned parallel to the traverse 17 platform 1. Thus, if a platform 1 is just swung out and thus one of its halves protrudes beyond its traverse 17 into the elevator space of the second platform 1, then the vertical passing of this second platform must be waited until the first platform 1 again pivots parallel to the traverse 17 and on the corresponding side of the elevator shaft, and only then can she cross this platform 1, be it on the way up or down. This condition for crossing the platforms 1 is monitored by a central computer and ensure compliance. When lying parallel to the traverse 17 platform 1 of the first elevator, the second but can be operated fully unrestricted. This fact helps this elevator system to provide additional redundancy sometimes an elevator will fail for some reason.

In Figure 2, the same view is shown, however, with two elevator platforms 1 and each a shared counterweight 7. But it could also be equipped with independent counterweights 7 both lift systems, either on both sides or only one each with corresponding support cables 6 of both Side of the cross member 17 on the single weight 7 on one side. In addition, the two telescopic linear bearings 26 are shown here, on which the turntable 2 is mounted, and whereupon the elevator platform 1 is attached. Further, it is shown here that the two halves of the circular disks are arranged separately and slightly spaced apart so that space is created for the elevator guide rails 8 and the two cross members 17. Front one recognizes one of the middle rails 28, while the rear middle rail 28 is shown in dashed lines. At these rails 28, the lift platform 1 struts over the struts 27 and is guided rolling on the rails 28, which gives the platform 1 a better stability, because then each platform 1 is constantly guided on three rails 8, 28.

In Figure 3, a single elevator platform 1 with Traverse 17, turntable 2 and a pivotable, wedge-shaped, curly end piece 19 is shown in the elevator shaft 13 seen from above. As can be seen, the cross member 17 extends on both sides beyond the inner edge 16 of the parking deck 14 and is also suspended outside the elevator shaft 13 on supporting cables. The elevator platform 1, which is mounted both on a telescopic linear axis 26 (FIG. 2) and on a turntable 2, extends laterally away from it. This turntable 2 allows the elevator platform 1 to pivot about the vertical axis with respect to the crossbar 17. This pivoting can be done by means of a hydraulic, pneumatic or electric motor. The end faces 21 of the elevator platform 1 are rounded, with a certain radius R. The elevator platform 1 is installed slightly laterally offset relative to this diametral 23. The traverse 17 extends itself directly adjacent to a diametrical 23, and beyond this diametrical 23 extends parallel to it, the cross member for the second elevator platform. On the outer side of the Extending platform are hinged to the end pieces 19, wherein in Figure 3, only one of the two end pieces 19 is located. This end piece 19 has an inner edge 24, the curvature of which corresponds to the radius R of the outer edge 21 of the end side of the elevator platform 1. Thus, the end piece 19 can be pivoted with its inner edge 24 along the outer edge 21 of the end of the elevator platform 1. For this purpose, a hinge mechanism that guides the tail 19 in accordance with the common center of these two circular curves. The two edges 21, 24 may also be designed so that one edge is guided directly on the other with respect to shear forces frictionally by the two edges 21, 24 together form a tongue and groove connection. This allows rollers with a small diameter and high loads to easily roll over this connection. The outer edge 20 of the end piece 19 fits with complete turning of the end portion 19 before the end of the elevator platform 1 to the contour of the inner edge 16 of the parking deck 14. This edge 20 is wedged with the inner edge 16 of the parking deck. This also creates a shear-resistant connection so that a vehicle can roll over this connection and still remain stable. With a second such end piece 19 on the opposite side of the elevator platform 1, this can be connected and locked on both sides with the plates of the parking deck 14.

On the elevator platform 1, a robot is constructed in its longitudinal direction, which has a central, extending in the longitudinal direction rail, with lateral, scissor-like extendable arms. The rail can extend telescopically in the longitudinal direction and drive under a standing on a parking deck vehicle and then slightly raise the vehicle at its four wheels with the laterally extendable arms, after which it rolls on robot belonging to steel rollers at the ends of its extendable arms. On these steel rollers, the vehicle can be pulled with the central rail on the elevator platform 1. When it has arrived there, it is lifted by lifting the elevator platform 1 to the calculated parking deck level, in which the computer determined the appropriate parking area. This parking area is located in one of the two circular halves and may be in another Therefore, the elevator platform 1 must be pivoted to the center of the corresponding circular half and in the right direction, which takes place via the turntable 2. This lateral movement and rotation about the vertical axis can occur during the lifting of the elevator platform, so that the lifting and pivoting movement of the elevator platform 1 are superposed on each other to take advantage of the lifting time for pivoting. Once the elevator platform has arrived at the correct level, the end pieces 19 are pivoted in front of the ends of the elevator platform 1 and wedged with the inner edge 16 of the parking deck 14. When this keying is completed, the robot can push the vehicle from the elevator platform 1 onto the parking area previously determined by the computer and park it on its vehicle wheels and retract again to the elevator platform 1. The end pieces 19 are unlocked again afterwards and the elevator platform pivoted back into the parallel position to the cross member 17 and moved back down to the initial state to pick up a new vehicle. Fetching a parked vehicle from any particular park field on any parking deck is done in exactly the reverse order.

Figure 4 shows this elevator in the interior of a concrete planned with mass parking garage with radially arranged parking areas in plan. The diameter of the elevator shaft is, for example 8.50m, and the parking areas have different lengths. Because the multi-storey car park is essentially designed with a quadrangular layout - albeit with rounded corners - it turns out that the parking areas, which are directed towards the corners of the quadrilateral, are the longest with a length of approx. 6m. They have a width of 2.20m. Accordingly, they can be used for particularly large and long vehicles, while shorter vehicles are parked on the shorter parking areas if possible. These also measure slightly less in width, namely only 2.13m. The support columns 25 for the elevator are arranged outside the elevator shaft 13, and the counterweights 7 in each case a remaining circular disc segment in the extension of the trusses 17. The trusses 17 then have a length of 10.70m and therefore project beyond the elevator shaft 13 on both sides by 1.10m , These two trusses 17 for The two elevator platforms 1 occupy a width of approximately 0.40 m and are guided on the rails 8, which extend along the support columns 25. A platform 1 is shown in dashed lines to show a state in which it is pivoted in the example shown by about 70 ° with respect to the crossbar 17, to operate the opposite parking area. So that a continuous Überfahrebene arises, an end piece 19 is pivoted in front of the end side of the elevator platform 1 on the side pivoted to the inner edge 16, as shown. Thus, a stable wedging with the parking deck is achieved, and sufficient stability for driving over a vehicle, because the roles of the robot on which the vehicle is pushed onto the parking area, allow only slight bumps. At the other end, the platform 1 remains free or can also be wedged with a second end piece 19, which is necessary for retrieving the vehicles in the direction of travel. Because of the vertical separation of the plant in two halves and a slot of 40 cm in this case, the lift shaft diameter depending on the rotational position of the elevator platform 1 is different, can be ensured with this shaping of the end pieces 19 on both sides of the lift platform 1 a closed transition to the parking deck plates 14 , FIG. 5 shows the elevator platforms seen from the side. The turntable 2 measures for example 2.20m in diameter. The storey heights vary here from 1.60m to 2.30m. The Traverse 17 measures 1.60m in height, is strutted in its interior several times with struts 3 and a total of 10.70m long. Laterally it is guided on the rails 8.

In Figure 6, the elevator platform of Figure 5 is shown in a view as seen in Figure 5 from the left. It can be seen here the turntable 2 under the elevator platform 1, and the support struts 3 for the platform construction, with which the platform 1 and its load is supported on the cross member 17. In addition, one recognizes the two lateral rails 8 for the two independently operable platforms 1, of which only one is shown here.
