Abstract
The present invention discloses a safety protection apparatus for elevators, which aims to protect passengers and special goods at each floor when the passengers and the special goods get in or out of the elevators. The present invention comprises an elevator control system, a floor gate position switch arranged on each floor of the elevator and a floor gate object detecting device, wherein the floor gate position switch is connected with the floor gate object detecting device and is connected to the input opening of the elevator control system; the floor gate position switch is used for judging the current floor where an elevator cage is positioned and determining the floor gate object detecting device of the floor whether to work; the floor gate object detecting device is used for detecting whether any passenger or good at the floor gate and inputting a signal to the elevator control system; after the elevator control system receives the signal that a passenger or a good is at the floor gate, the gate of the elevator can not be closed.
Description
Technical field
The present invention relates to a kind of safety guard, especially relate to the safety guard of elevator.
Background technology
Along with the continuous development of society, more and more be subject to people's attention as the safety in utilization of the elevator of vertical transportation instrument.Particularly because modem elevator industry flourish, its application is also more and more wider, also arises at the historic moment such as being used for the car elevator of transporting cars.Because the special purpose of all kinds of elevators, the protection during for special articles such as using escalator personnel and automobile turnover elevator seems more and more important.At present, existing elevator safety fender guard can only be implemented limited protection in the lift car entrance.(international publication day: on January 8th, 2004), it only relates to elevator in process is opened the door or opened the door in preparation, prevents that foreign matter from snapping between elevator door and the gangway framework as international patent publications specification sheets WO2004002869A1.If the area discover obstacle between elevator door and gangway framework then takes to stop the safety method that opens the door action or open the door slowly or oppositely close the door.This patent can't realize that personnel or the article to the turnover elevator grant asylum in the closed procedure of elevator door pass.The described elevator safety fender guard of Japanese Patent JP53-49868U and for example; it can't judge lift car floor of living in; circulate a notice of corresponding information also can't for the personnel of the elevator doorway of lift car floor of living in floor in addition, that elevator will soon be stopped, thereby implement protection.
Summary of the invention
The objective of the invention is to above-mentioned deficiency at prior art; a kind of device of implementing protection just can be to using escalator personnel and special article turnover elevator at the elevator floor stops place time is proposed; prevent the action of closing the door of elevator door, to protect the bump that expansion personnel or object are not subjected to elevator door.The present invention can also in time circulate a notice of the floor command information of registering in the lift car personnel to the elevator doorway of corresponding floor, will abdicate respective channel at personnel or automobile that equivalent layer is stood out to give in the elevator.
Above-mentioned purpose of the present invention is achieved through the following technical solutions: comprise apparatus for controlling elevator and the layer door article detection device that is built up in each stop of elevator; Whether described layer door article detection device is used to detect the elevator door place personnel or object, and signal is inputed to described apparatus for controlling elevator; After described apparatus for controlling elevator receives the signal of personnel or object, prevent closing of elevator door, also comprise the layer door position switch that is built up in each stop of elevator; Described layer door position switch and layer door article detection device link to each other and are connected to the input port of described apparatus for controlling elevator, and a described layer door position switch is used to judge lift car floor of living in, determines whether a layer article detection device of this floor works.
Also comprise the stop control setup and the stop communication device that are built up in each stop of elevator, described stop control setup links to each other with stop communication device and attaches to the delivery port of described apparatus for controlling elevator, when described apparatus for controlling elevator obtains the registering signal of lift car, to described stop control setup output command, described stop control setup is accepted the instruction of described apparatus for controlling elevator and to described stop communication device output signal; Described stop communication device is accepted the signal of described stop control setup, and sends the circular signal; Described stop communication device is the aviso device of light or sound.
Compare with prior art, the present invention has following beneficial effect: be implemented in when each stop place of elevator just can pass in and out elevator to special articles such as personnel and automobiles and implement real-time protection, and more safe and reliable.
Description of drawings
Fig. 1 is a scheme drawing of the present invention;
Fig. 2 is a diagram of circuit of the present invention;
Fig. 3 is a diagram of circuit of the present invention.
Wherein, n1 is the layer door position switch of n layer; N2 is the layer door article detection device of n layer; N3 is the stop control setup; N4 is a stop communication device; 30 is apparatus for controlling elevator.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described.
As shown in Figure 1, the present invention includes apparatus for controlling elevator 30, also comprise the layer door position switch n1, the layer door article detection device n2 that are built up in each stop of elevator; A layer door position switch n1 and layer article detection device n2 links to each other and is connected to the input port of described apparatus for controlling elevator 30; Also comprise the stop control setup n3 and the stop communication device n4 that are built up in each stop of elevator, described stop control setup n3 links to each other with stop communication device n4 and attaches to the delivery port of described apparatus for controlling elevator 30.
As shown in Figure 2, elevator is in automatic running state, starts the safety protection program of apparatus for controlling elevator 30.When elevator runs to the n layer, elevator stops layer at the n layer and opens the door, and start the layer door article detection device n2 of corresponding n layer, and the layer door article detection device of all the other each layers is not worked.When not having personnel or object (as automobile) in certain detection range on this layer doorway, this moment layer door position switch n1 closure, apparatus for controlling elevator 30 receives this output signal of door article detection device n2 layer by layer, allows elevator to close the door.When personnel or object (as automobile) are arranged in certain detection range on this layer doorway; layer door position switch n1 opens; apparatus for controlling elevator 30 receives this output signal of door article detection device n2 layer by layer; and through handling; prevent the action of closing the door of elevator door, be not subjected to the bump of elevator door with protection personnel or object (as automobile).
As shown in Figure 3, elevator is in automatic running state, starts lift car instructs registration disposal system in the apparatus for controlling elevator 30, starts relevant stop control setup n3 simultaneously.When in the lift car instructs registration being arranged, apparatus for controlling elevator 30 will be exported a signal, this signal is defeated by stop control setup n3, the stop control setup n3 that corresponds to the instruction floor of registering in the car outputs signal to device stop communication device n4 (this stop communication device can be the aviso device of light or sound), n4 sends the circular signal by stop communication device, warn the personnel or the automobile at corresponding stop place and take corresponding action, give in the elevator and will abdicate respective channel at personnel or automobile that equivalent layer is stood out.
