Definitions
- the present invention relates to an elevator installation reduced pit depth.
- the Invention securing the pit or setting it up a temporary shelter in the shaft pit.
- EP 0 129 678 A1 is an automatic device to secure a temporary work space in the Well known, the mechanical one as a route limitation lever adjustable in the travel path of the car includes. When opening a door leading into the pit the lever is forced into its the travel path of the car limiting securing position pivoted, with pivoted lever interrupted the operation of the elevator is.
- JP-A-03056378 is a device for limiting the travel path known, which at times on a guide rail stopper element to be provided includes a car to prevent driving under a predetermined position.
- the stopper element is at one end at an outside the axis of rotation located on the guide rail and can about this axis of rotation in a protruding into the track Position can be rotated.
- the well-known guideway limiter has the disadvantage that the car only at one point on his Outer edge is supported. When the car is heavily loaded or at a somewhat higher impact speed the car warps the known guideway limiter. In addition, the guide rail with the existing load slightly bent.
- the known braking and safety devices are usually via a speed limiter or a so-called slack rope detection triggered.
- the trigger can be both mechanical and electrical, but also on other ways such as pneumatic or hydraulic.
- the braking device is actuated / triggered, when a person wants to enter the pit. On the one hand, this can be done consciously by the person himself Pressing an appropriate button, pulling one Lever or the like happen.
- This in particular electrical or mechanical device for triggering the Braking device (release device) is preferably outside arranged of the elevator shaft, and is by the Person actuated before entering the elevator shaft.
- the access door is a particularly advantageous embodiment of the elevator shaft e.g. through a so-called emergency release can only be opened if the triggering device has been actuated beforehand has been.
- the catching / braking device can preferably be activated, when the car is in a predetermined or predeterminable distance to the pit floor or the Car falls below this minimum distance.
- the triggering device is also available one of the lower access doors (and possibly other Doors) to the elevator shaft in operative connection, so that at one manually opening the door automatically triggering the Braking device takes place.
- This has the advantage that the Braking device even when entering the shaft a person who has no knowledge of someone outside the Tray arranged triggering device has triggered becomes.
- the activation advantageously takes place when opening the door only when the car is in a predetermined or predeterminable height above the shaft floor. This height is given, for example, if between the front lower edge of the car and the shaft door floor a person can slip through.
- means for activating in the pit should be provided directly upon entering the pit are operated automatically and the Trigger the braking device.
- release devices can be, for example, light barriers (with light in the visible or invisible area), sensor mats (contact or step protection mats), gratings or step plates, Tension wires, or other known triggering options act when entering / interrupting or otherwise Actuation of a signal to trigger the braking device generate or trigger the braking device directly.
- Further Trigger options include the use of ultrasound or radar, inductive and / or capacitive means or agents based on piezo effect.
- the mats / grids can be supported over the whole area or only in areas and can have switches with path or pressure evaluation.
- sensors in the car shaft provided that trigger the braking device as soon as the car is a minimum height above the shaft pit floor falls below. The sensors are only after previous Opened the access door activated.
- the triggering device advantageously comprises a Circuit device with two stable states that at Actuation of the trigger device from its first stable State is placed in the second stable state. Consequently prevents, for example, when closing the Access door through the person in the shaft and the associated closing of the circuit of the trigger device the braking device is deactivated again.
- the switching device with the two stable states remains after closing the access door, leaving the Floor mats etc. in the second stable position, and can only operated again from outside the shaft and into the Starting position to be reset. During this time the braking device is triggered so that no movement of the car or no movement of the car into the lowest stop is possible.
- the braking device is a safety gear, so takes place after the actuation according to the invention with a further downward movement of the car e.g. a Blockage of the pliers on the guide rails so that the The car stops.
- the braking device is independent of upstream Speed sensors or a speed monitor triggered directly.
- safety gear or braking devices can also be used on suspension or brake cables or a piston brake for hydraulic cylinders (for hydraulic elevators).
- a brake device can also be used for guide rail-less elevators for holding or wedging on the shaft walls or used on brake rails. Is the elevator shaft formed as a shaft structure, the braking device also attack directly on parts of the scaffolding.
- a guideway limiter in the path of the car can be introduced.
- the introduction of the guideway limiter can be done manually or automatically.
- the invention also includes a method for operating a Elevator system, in which a temporary shelter under one Elevator car is set up in which a Braking device (already available with a rope elevator) is activated.
Abstract
Description
- die Aktivierung der Bremsvorrichtung mechanisch erfolgt, durch mechanische Blockierung des Fahrwegbegrenzers oder mechanische Auslösung der Schlaffseilerkennung;
- eine Bewegung der Trittplatte die mechanische Aktivierung auslöst;
- die Aktivierung von außerhalb des Schachtes durch elektrische oder mechanische Auslöseeinrichtungen erfolgt;
- die Aktivierung von außerhalb des Schachtes über Schalter oder Hebel erfolgt;
- die vorbestimmbare Höhe vorgegeben ist, bevor zwischen unterer Fahrkorbvorderkante und Schachttürboden eine Person durchschlüpfen kann;
- die Aktivierung erfolgt, wenn die Notentriegelung der Türen im unteren Schachtbereich betätigt wird.
Claims (11)
