DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a vehicle transporting arrangement in a parking building for transporting automatically a vehicle from a drive-in module to a parking place, said transport arrangement including a first carriage which can be moved on and between different parking floors or storeys in the building and which carries a second and a third carriage, wherein each of said carriages includes lifting means for lifting and supporting a vehicle wheel-pair and said carriages being positioned sequentially in a direction perpendicular to the direction of movement of the first carriage on a parking floor and being movable relative to the first carriage in a direction perpendicular to its direction of movement on a parking floor.
BACKGROUND OF THE INVENTION
Vehicle transport arrangements of this kind are known from SE-B-459 110, SE-B-463 219 and SE-B-465 585 and function relatively well. However, it has been found difficult to satisfactorily resolve the problem of moving the vehicle supporting carriages relative to the transfer carriage which carries these carriages as they are transported from and to a respective drive-in module and drive-out module to and from a location opposite a parking space and into and out of a parking space respectively. One cause which contributes to these difficulties is that the distance through which the vehicle, and therewith the vehicle-carrying carriages, shall be moved coincides essentially with the extension of the transfer carriage in the direction of vehicle movement and is therewith long in relation to the space at the disposal of the vehicle moving devices. The transport arrangement described in SE-B-463 219 uses linear gearing which includes two rods that can be moved relative to one another and which are driven by a relatively complicated chain mechanism, said gearing taking-up a relatively small amount of space when the rods are retracted.
SUMMARY OF THE INVENTION
The primary object of the present invention is to solve the problem of moving the vehicle-carrying carriages relative to the transfer carriage to and from a parking space, without using telescopic devices of one kind or another and without requiring a large amount of space to accommodate the vehicle moving arrangement.
This object is achieved in accordance with the invention by means of a vehicle transporting arrangement of the kind defined in the introduction which is characterized in that at least one of the second and the third carriages includes drive wheels and drive means for moving the carriage in relation to the first carriage.
According to one preferred embodiment, only one of the second and the third carriages is equipped with drive wheels and drive means and the second and third carriages are joined together by means of a variable length connection. The second or the third carriage is belt-driven and the belts of said second and third carriages run on rails mounted on the first carriage and also at each parking space, and the second and third carriages are provided a mutually remote ends thereof with brushes which brush the rails clean as respective carriages move therealong. Each belt of the second and the third carriages has provided centrally on its inner surface a longitudinally extending rib which engages a respective groove provided on each wheel of the second and the third carriages, thereby to prevent the belts sliding sideways on the wheels and ensuring that the second and the third carriages will move in a straight line.
In order to ensure that a vehicle will always be moved into a correct vehicle depositing position in a parking space, the parking space is equipped with position sensors which disclose when the second and the third carriages, and therewith also a vehicle carried thereby, are located in a vehicle parking position in a parking space. The first carriage is also equipped with position sensors which disclose when the second and the third carriages, and therewith a vehicle carried thereby, are located in a transport position on the first carria
