摘要:
A plurality of express shuttle elevators S1-S4 exchange elevator cabs at a transfer floor 26 with local elevators L1-L10 by means of a carriage 107, the casters of which 93 are guided by tracks 70-83. The transfer floor has linear induction motor (LIM) primary segments 60-67 disposed on the transfer floor; the carriage has a LIM secondary 128 thereon for propulsion. The carriages can be locked 91, 92 to the transfer floor for loading, and cabs can be locked 131 onto the carriages for stability when being moved. A controller (FIGS. 10-13) keeps track of the progress of the cabs from one elevator to another.
摘要:
An elevator system provides service between a ground level and each of three upper levels through a single elevator shuttle hoistway system. Three elevator cabs 34-36, B, D, F are moved in a triple deck elevator car frame 35, or a four deck elevator car frame 75 in a low hoistway 26, 76; two cabs are moved in a double deck elevator car frame 30 or four deck car frame 76 in a mid hoistway 27, 52; and one cab is moved in a single deck car frame 31 or triple deck car frame 77 in a high hoistway 28, 53. Other embodiments have other car frame arrangements.
摘要:
A safety gate (24) is slidable vertically from an upper position at an elevator cab landing (22) where it obstructs movement of the elevator cab (20) into a hoistway, and a lower position that permits cab travel between a car frame (29) and the landing. An actuator (42) normally urges the gate upwardly; the actuator is moved by a cam assembly (36) on an approaching elevator car frame so as to slide the gate (24) downward, out of the way of cab motion.
摘要:
An elevator shuttle includes a plurality of elevator hoistways (14, 19, 24) which overlap, the elevator car frames (13, 21, 25) traveling in each hoistway including two decks per cab being carried by the car frame, plus an extra deck on car frames (20) in other than the highest (24) and lowest (14) hoistways. This allows cabs (C) traveling simultaneously, upwardly, in three or more hoistways to pass cabs (A, B) simultaneously traveling downwardly in those hoistways. The cabs may be loaded and unloaded while in the hoistway (FIGS. 1, 13, 21) or while in off-hoistway landing areas (FIG. 28). Embodiments include one cab per hoistway and two cabs per hoistway; three hoistways and four hoistways.
摘要:
To prevent elevator rope stretch effects when a horizontally transferable elevator cab (18) is rolled onto and off of an elevator car frame (10), an elevator car/floor lock (31) includes a bolt (47) which extends across the interface between the car frame and the building and engages a strike (39). Jack screw (44) and solenoid (60) embodiments are shown. To take the weight off the lock bolts so that they may be retracted to permit moving the car frame vertically in the hoistway, strain gages (64, 65) or load sensors (62, 63) provided in or adjacent the bolts sense the weight supported thereby, and a pretorque program (FIG. 6) provides armature current to the hoisting motor to raise or lower the car frame sufficiently to reduce the load on the bolts to nil.

摘要:
Elevator cabs are transferred between elevators, which may be shuttles, in various levels of a building, such as transport floors, in response to car calls registered in the cabs and hall calls registered on the transport floors. The cabs may be transferred from carriages or bogeys onto elevator car frames in a lateral direction, which is perpendicular to the motion of the cab on a carriage or bogey, or in a longitudinal direction which is the same as the direction of motion of a cab on a carriage or bogey. The horizontal/vertical control and transfer may be effected in response to the arrival at transport floors of elevators having cabs therein, or in response to the arrival at an elevator of a bogey carrying a cab which must be transported between a transport floor on one level of a building and a transport floor on another level of a building, in order to serve the need of a car call registered therein or a hall call. The horizontal transportation may occur on transport floors within a building, or may extend between different building segments or between different buildings.
摘要:
An elevator cab X is moved from a hoistway TL to a car frame (11) simultaneously with moving a cab Y from the car frame (11) onto a landing TR. Double deck car frames (11a) may be utilized with cars P, Q going in the opposite direction of cars X, Y as they are transferred between the car frame and corresponding landings.
摘要:
Horizontally moveable elevator cabs A-E are transferrable between the car frames (72) of two elevators HI, LO in adjacent hoistways which extend between at least three levels (GND, MID, SKY) of a building, and between the car frames and landings L, R at said levels. The vertical movement of cars in the hoistways is synchronized, and transfer of elevator cabs between landings and car frames is simultaneous.
摘要:
A socket plug assembly (44) on an elevator cab (10) may engage with complimentary socket plug assemblies (46) on either of two car frames (11, 13) when it is horizontally moved therebetween. A socket plug assembly (44a) on a horizontally moveable elevator cab may have a horizontal interface with a complimentary socket plug assembly (45b) mounted on an elevator car frame or landing, and one of them is moved vertically to cause engagement with the other. Socket plug assemblies (169) tethered to a cab (10) by means of an umbilical cord (168) is engageable with socket plug assemblies (170, 171) on booms (172, 173) on the elevator car frames (21, 22) or landings. An uninterruptible power supply (50) maintains power when the cab is unplugged; a transceiver (51) on the cab maintains communications with a transceiver (62) in the building when the cab is unplugged.
