摘要:
Disclosed is an elevator system (200A), including a hoistway (117); an elevator car (103) in the hoistway; sensors (220) in the hoistway operationally coupled to the elevator car and configured to capture sensor data indicative of a person (210) being in the hoistway, and a processor (115) configured to determine from the sensor data that the person is in the hoistway; and wherein the elevator car is configured to reduce speed or stop when the processor determines the person is in the hoistway.

An elevator buffer has: a base cylinder; a plurality of plungers; and a plurality of forcing bodies. The base cylinder has: a base portion; and a cylinder portion that is disposed on the base portion. A hydraulic fluid is kept inside the cylinder portion. The plurality of plungers are coupled sequentially so as to be slidable upward from the cylinder portion. The respective plungers are vertically displaceable separately relative to the cylinder portion while being subjected to resistance from the hydraulic fluid. The plurality of forcing bodies, which separately force the respective plungers upward away from the base portion, are disposed side by side on the base portion.

A retractable stop and the method of use thereof to control travel range of an elevator system are disclosed. The retractable stop may include a vertical mounting bracket, an impact plate, and a support member. The support member may include an upper end pivotably connected to a distal portion of the impact plate and a lower end movable in relation to the mounting bracket. The proximal portion of the impact plate may be pivotably connected to the mounting bracket. When the retractable stop is in a retracted position, the impact plate does not significantly contribute to the lateral profile of the retractable stop.

The method comprises unlocking and opening a landing door (25) at a lowermost landing (L1) manually, activating a first stop button (P1) in the shaft (20), whereby a safety circuit (S1, S2) of the elevator is opened so that operation of the car (10) is completely prevented, entering into the shaft (20), closing the landing door (25), climbing down from the lowermost landing (L1) to the pit (22), turning a drive switch (SW1) in a maintenance control unit (100) positioned in the pit (22) into a maintenance drive mode, whereby the first stop button (P1) is by-passed so that the car (10) can be driven from the maintenance control unit (100) upwards and downwards in the shaft (20).
摘要:
The present invention relates to a safety arrangement of an elevator, which comprises a mechanical safety device (3, 4, 11) that ensures the safety of the elevator hoistway (2) and can be moved into a use position, and which safety arrangement of an elevator comprises a detector (5) of intrusion into the elevator hoistway, which detector is fitted to receive measuring data (6) from the sensors (7) that measure the status of the entrances (9, 10) of the elevator hoistway, and also to determine intrusion into the elevator hoistway (2) from the measuring data received, and after determining an intrusion to switch the safety arrangement of the elevator into an operating mode (8) in which driving with the elevator is prevented. The aforementioned detector (5) of intrusion into the elevator hoistway is fitted to determine on the basis of the measuring data (6) received the area of intrusion (9, 10) from where intrusion into the elevator hoistway (2) has occurred, the safety arrangement comprising a service drive unit and the detector of intrusion into the elevator hoistway is fitted to delimit a safe area (27, 28) of the elevator hoistway corresponding to the determined area of intrusion (9, 10), and the safety arrangement of the elevator is fitted to permit service drive after the mechanical safety device (3, 4, 11) that is disposed in the safe area (27, 28) delimited by the detector (5) of intrusion into the elevator hoistway and that ensures the safety of the elevator hoistway is moved into the use position, and that the service drive unit is disposed in the pit of the elevator hoistway.

In an elevator shaft (100), preferably having an anti creeping device (140) and reduced ends, the reduced ends being the elevator pit and the elevator overhead, a load sensing safety apparatus (110) facilitated to activate the emergency safety gear of the elevator, according to teachings of the present invention, the load sensing safety apparatus including a movable plate, one or more spacing devices (120) one or more pressure sensors (150), and a locking trigger mechanism for triggering the activation of the emergency safety gear of the elevator.
摘要:
The invention relates to an elevator safety arrangement and a method for implementing safety spaces in an elevator shaft. The safety arrangement of the invention comprises a mechanical safety device which can be set to a working position to ensure a sufficient safety space in the elevator shaft and an electric safety system for identifying the operating state of the mechanical safety device. According to the method of the invention, detectors comprised in the electric safety system are read by an electric safety controller and, when a functional deviation is detected, one or more stopping devices are actuated to bring the elevator system into a safe operating state.
摘要:
The present invention relates to a device and procedure for creating and securing a temporary safety space within an elevator hoistway (12) such that a service or maintenance technician can work with impunity from a car (2) entering the safety space. In particular, the invention provides a stop bar (20) for installation between and in engagement with opposing guide rails (12) of the hoistway (12) to prevent upward or downward movement of the car (2) or a counterweight.
