Elevator device that transmits inspection data when inspection operation after earthquake is interrupted
An elevator device includes an operation control unit (18), a storage unit (22), a transmission unit (23), a determination unit (25), and a recovery unit (26). When an inspection operation is interrupted by the operation control unit (18), the transmission unit (23) transmits inspection data stored in the storage unit (22) to a plurality of specific devices (20). The determination unit (25) determines whether or not recovery conditions are satisfied on the basis of a plurality of responses from the devices (20) to which the transmission unit (23) transmits the inspection data. For example, the recovery unit (26) restores a normal operation when the determination unit (25) determines that the recovery conditions are satisfied.
WATER DETECTION INSIDE ELEVATOR PIT
A method of detecting water within a pit of an elevator shaft including: emitting an electromagnetic wave from an electromagnetic wave source towards a bottom of an elevator shaft; detecting a reflected electromagnetic wave of the electromagnetic wave using an electromagnetic wave detector; and determining whether water is present within the pit of the elevator shaft in response to the reflected electromagnetic wave.
WATER DETECTION IN ELEVATOR PIT USING PIT SENSORS
A method of detecting water within a pit of an elevator shaft including: detecting water within a pit of an elevator shaft using a water sensor; wirelessly transmitting a notification to a controller; and transmitting the notification to a computing device.
Elevator derailment detection device
A derailment detection apparatus for an elevator includes a conductive line, an upper support device configured to support an upper end portion of the conductive line, a lower support device configured to support a lower end portion of the conductive line, a contact element, which is installed on an ascending/descending body, and is brought into contact with the conductive line when the ascending/descending body derails from guide rail, and a detection unit configured to detect contact of the contact element with the conductive line. The lower support device is fixed to the guide rail by fastening a fastener, and is allowed to move upward and downward along the guide rail by loosening the fastener. The lower support device includes a guide portion configured to guide upward and downward movement of the lower support device along the guide rail.
ELEVATOR DEVICE
Provided is an elevator device including a main rope configured to support a car and a counterweight, a hoisting machine configured to be driven with the main rope wound therearound, a hoisting-machine controller configured to control the hoisting machine, a car brake controller configured to control a car brake device configured to apply a load to car rails to control raising and lowering of the car, and a vibration detection device configured to detect vibration of the car. When the vibration of the car is detected based on an output signal from the vibration detection device under a running state in which the hoisting-machine controller controls drive of the hoisting machine, the car brake controller controls the car brake device to generate a braking force until the vibration becomes smaller than a set value.
DATA TRANSMISSION VIA ELEVATOR SYSTEM TENSION MEMBER
A tension member for an elevator system includes one or more tension elements extending along a length of the tension member, and one or more a wave guide regions secured to at least one surface of the tension member or integral to the tension member and extending along the length of the tension member. The one or more wave guide regions are configured for transmission of a radio frequency (RF) data signal along the one or more wave guide regions.
Elevator system control based on building sway
An illustrative example method of controlling an elevator situated in a hoistway of a building includes detecting sway of the building, determining characteristics of the detected sway including a plurality of frequencies and associated periods of the sway, determining an expected sway of an elongated member of the elevator system based on the determined characteristics, and controlling at least one of position and movement of an elevator car in the hoistway based on the expected sway.
ELEVATOR SEISMIC PERFORMANCE APPARATUS
An elevator car of an elevator system includes a car body, and a car frame supportive of the car body. The car frame includes two or more opposing upright assemblies, a crosshead assembly located above the car body, and a plank assembly located below the car body. A plurality of seismic retainers are located at each of the upright assemblies. The plurality of seismic retainers are configured for a non-contact relationship with a guide rail of the elevator system during normal operation of the elevator system, and configured to react guide rail loads during a sway event via contact with the guide rail.
HOIST AND HOIST ELEVATOR AND CONTROL SYSTEM
A hoist elevator control system and a hoist elevator for a multi-story building structure on a building site, comprises an enclosure for raising and lowering personnel and materials. The control system comprises a sensor external to the enclosure, a sensor internal to the enclosure, a call button at each floor, and a processor located within the enclosure. The processor obtains data from the sensors and the call buttons and provides output to a display screen in the enclosure and to an external control location. The internal sensor may be a people counter that issues an alarm to prevent operation when the enclosure has more than a preset number of people within. The people counter may send the current number of people within to the processor for processing, and data may allow an operator to control the elevator, for example via a cloud connection and/or a telephone application.
METHOD AND AN ELEVATOR FOR AUTOMATIC ELEVATOR CONDITION CHECKING
A method and an apparatus for automatic condition checking of an elevator are provided, wherein an elevator car of the elevator is situated in a door zone of a first landing in an elevator shaft following an earthquake. The method includes determining whether the load carried by hoisting ropes is evenly distributed between the hoisting ropes by checking the status or measurement data of at least one rope tension measurement device. The test unit determines whether the elevator car is empty and conducts a drive test for the elevator car in order to determine unimpeded access for the elevator car to other landings. The elevator is returned to normal use, if the drive test indicates unimpeded access for the elevator car to the other landings.
