Abstract
A method for detecting if the doors at different floors are also opened when an elevator's cage is stopped at current floor is disclosed. If one or more doors at other floors are opened, the elevator can not continue to run. Its equipment is also disclosed.
Description
Technical field
The present invention relates to a kind of method of inspection that opens the door of elevator safety loop, also relate to the device of realizing the method for inspection that opens the door in this elevator safety loop.
Background technology
In order to protect personnel's safety; elevator need detect gate and the switch that is installed on the layer door of each stop; have only after the layer door of the gate of elevator and all stops all closed, elevator could move, and the elevator safety standard of various countries has all been made strict regulation to this.The general way of realization that adopts as shown in Figure 1 of the detection of in the safety return circuit elevator being closed the door, the layer door when this device can move elevator opened and detected, and has only behind all switch closures, and elevator could normal operation.And some national elevators is installed and the safe handling standard more clearly stipulate to be installed in dwelling house and can be opened the elevator of layer automatically and should equip the device that can cut off control circuit when the stranger enters the hoistway of elevator, and can only be recovered the operation of elevator by machine room.This layer that just requires to stop except that car is current other layer the layer is opened to the action that the people can enter the size of hoistway and all should be detected.Existing device shown in Figure 1 can't satisfy this requirement, GS is a gate switch among the figure, DS-1 to DS-n is a layer door switch, when elevator stops layer when opening the door, gate switch disconnects with the layer door switch that stops layer, so this series loop disconnects, but at this moment, this device can not detect the layer door opening action of other stop.For example, when elevator after the 2nd buildings stop to open the door, GS and DS-2 disconnect, and are disconnected to period of contact at it, if having the layer door of other stop once to be opened and closed once again, then this action can not be detected.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of method and device that improves the elevator safety performance is provided.
The technical scheme of the inventive method is: detect when elevator is in and stop non-ly under the door opening state currently stopping layer by layer whether door is opened, except the residing stop of car, the layer door of other any stop opened all and will be detected, and stops the continuation operation of elevator, up to being recovered by machine room.The technical scheme that realizes the device of the method that above-mentioned detection elevator door is opened is: increase by an auxiliary security loop in elevator safety loop, each stop is set up two auxiliary contacts, an auxiliary contact, and it is closed under the state to close the door fully, disconnects when opening the door; Another auxiliary contact, the state of closing the door fully disconnects, and it is closed to certain size (the inaccessiable size of people) back to open the door, and just disconnects behind door-closing in-place; This two auxiliary contacts parallel connection, every pair of each layer contact is together in series then.
The invention has the beneficial effects as follows: guarantee to open the door the residing stop except the car flat bed, the layer door of other any stop opened all and will be detected, and stops the continuation operation of elevator, up to being recovered by machine room, thereby improved the safety performance of elevator.
Description of drawings
Shown in Figure 1 is the block scheme of existing device;
Shown in Figure 2 is the block scheme of one embodiment of the invention.
Wherein, DS-1 ' is the newly-increased contact of being located at each stop to DS-n ', and the state closure of closing the door disconnects when opening the door; ADS-1 to ADS-n is the contact of setting up in each stop, and this contact state of closing the door disconnects, and it is closed to certain size (the inaccessiable size of people) back to open the door, and just disconnects behind door-closing in-place.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
As shown in Figure 2, DS-1 ' is the newly-increased contact of being located at each stop to DS-n ', and the state closure of closing the door disconnects when opening the door; ADS-1 to ADS-n is the contact of setting up in each stop, and this contact state of closing the door disconnects, and it is closed to certain size (the inaccessiable size of people) back to open the door, and just disconnects behind door-closing in-place.When elevator when certain one deck stops to open the door, the 2nd buildings for example, controller is through starting the detection in opposite house loop after the certain time-delay, this moment the ADS-2 closing of contact, though DS-2 ' disconnections, this moment the 2nd buildings the contact to still keeping connection, make this loop be in connected state, at this moment, if other layer, for example the floor in the 3rd buildings door is opened, DS-3 ' disconnection, then this loop disconnects, and makes controller detect the action of opening the door of other stop before the ADS-3 closure, thereby stops elevator to continue operation.At this moment, even the floor in the 3rd buildings door is closed, elevator can not resume operation, and elevator could normal operation after carrying out recovery operation at machine room.
Claims (2)
1. the method for inspection that opens the door of an elevator safety loop, it is characterized in that: be in when stopping layer door opening state at elevator, detect when elevator is in and stop non-ly under layer door opening state currently stopping layer by layer whether door is opened, except the residing stop of car, the layer door of other any stop opened all and will be detected, and stop the continuation of elevator to move, up to recovering by machine room.
2. device of realizing the method for inspection that opens the door of the described elevator safety loop of claim 1 is characterized in that: set up two auxiliary contacts respectively at each stop of elevator, and this two auxiliary contacts parallel connection, every pair of each layer contact is together in series then; A described auxiliary contact, it is closed under the state to close the door fully, disconnects when opening the door; Another auxiliary contact, the state of closing the door fully disconnects, and it is closed to certain size (the inaccessiable size of people) back to open the door, and just disconnects behind door-closing in-place.
