VEHICLE ELEVATOR AND CONVEYOR ARRANGEMENT

摘要

A vehicle elevator and conveyor arrangement in a parking building of the kind in which the vehicle is intended to be conveyed in the building without the assistance of a driver. The conveyor arrangement includes a so-called transfer carriage which is intended to raise and lower all wheels of the vehicle and which can be moved in a horizontal plane in the building and also in a vertical direction by means of the elevator arrangement, which elevator arrangement includes an elevator platform for supporting a transfer carriage. Each of the stories or floors of the parking building on which a transfer carriage (31) is intended to be moved is provided with two parallel rails (50, 51) which form a horizontal transfer-carriage conveyor path or track (71). One or more elevator shafts (61, 62) are positioned along the longitudinal extension of the rails. The wheels (52-59) of the transfer carriage can be displaced from a position (55') in which the track width of the transfer carriage (31) corresponds to the distance between the running or bearing surfaces of the rails (50, 51) to a position (55") in which the track width is smaller than this distance. The elevator platform includes a plate whose length (L) is shorter than the distance between the rails (50, 51). Lifting attachments project from the elevator platform (40) in the longitudinal direction thereof. The rails (50, 51) are interrupted in the vicinity of respective elevator shafts, so as to allow vertical passage of the lifting attachments. The longitudinal extension of each interruption in the rails (50, 51) is shorter than the axle distance between the wheels (52-59) of each wheel pair of the transfer carriage (31), so that a transfer carriage is able to pass an elevator shaft in the horizontal direction.
