Abstract
The utility model discloses a kind of elevator light curtain, which solve the technical matters of traditional elevator light curtain poor practicability.The utility model comprises projector and the receptor that correspondence is located at elevator door both sides, this projector and receptor are all connected with light curtain circuit, multiple infrared trace light beam is formed between this projector and receptor, this light curtain circuit is provided with shielding control circuit, this shielding control circuit alternative masked segment infrared trace light beam.Shielding control circuit is equipped with by allowing on light curtain circuit, and this shielding control circuit alternative masked segment infrared trace light beam, therefore the utility model can according to the needs of applicable situation, mask a branch of or a few bundle infrared trace light beam between projector and receptor, the judgement making them not participate in infrared trace light beam whether to be blocked, elevator light curtain can be avoided thus because the structural limitations of lift facility itself, and cannot normally run, therefore the utility model has the simple and practical feature of structure.
Description
Technical field
The utility model belongs to mechanical field, and it relates to a kind of elevator light curtain, is related specifically to a kind of elevator light curtain.
Background technology
Elevator light curtain is a kind of light formula safety protector of elevator door, is applicable to elevator, Cargo Lift, is used for protecting the safety of passenger.It mainly comprises the infrared transmitter and receptor that are arranged on elevator cage door both sides, and in the course of the work, transmit-receive tube is opened according to this, from top to bottom continuous scanning gate region, forms an intensive infrared ray protection light curtain.When wherein any Ray Of Light is stopped; control system exports enabling signal immediately, gate and phase down unlatching of reversing, until passenger or obstacle leave warning region after elevator door can normally close; thus reach the object of safety guard-safeguard, elevator can be avoided like this to press from both sides the generation of people's accident.This elevator light curtain in the course of the work, forms multiple infrared trace light beam between projector and receptor, wherein any a branch of or a few bundle infrared trace light beam is blocked, and light curtain circuit will know that this blocks signal, and exports door open command.And in some special occasions, due to the stop of some ad hoc structure or parts on elevator door, a branch of or a few bundle infrared trace light beam may be caused to be blocked, and this makes this common elevator light curtain normally to use, and namely this elevator light curtain also exists the shortcoming of poor practicability.
Utility model content
The purpose of this utility model is the elevator light curtain providing a kind of structure simple, easy to adjust and practical.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of elevator light curtain, comprise projector and receptor that correspondence is located at elevator door both sides, this projector and receptor are all connected with light curtain circuit, multiple infrared trace light beam is formed between this projector and receptor, this light curtain circuit is provided with shielding control circuit, this shielding control circuit alternative masked segment infrared trace light beam.
Above-mentioned a kind of elevator light curtain, this shielding control circuit is connected with control button, and this control button comprises forward select button, Low market efficiency button, acknowledge button and cancel button.
Above-mentioned a kind of elevator light curtain, this control button is located on the control desk of light curtain body.
The beneficial effects of the utility model are: be equipped with shielding control circuit by allowing on light curtain circuit, and this shielding control circuit alternative masked segment infrared trace light beam, therefore the utility model can according to the needs of applicable situation, mask a branch of or a few bundle infrared trace light beam between projector and receptor, the judgement making them not participate in infrared trace light beam whether to be blocked, elevator light curtain can be avoided thus because the structural limitations of lift facility itself, and cannot normally run, therefore the utility model has the simple and practical advantage of structure.On the other hand, this shielding control circuit is connected with control button, just can be masked the infrared trace light beam needing shielding easily, can strengthen practicality of the present utility model further thus by regulable control button.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the schematic diagram of infrared trace light beam of the present utility model.
Detailed description of the invention
Further understand for making to have architectural feature of the present utility model and effect of reaching and be familiar with, coordinate detailed description in order to preferred embodiment and accompanying drawing, be described as follows:
As depicted in figs. 1 and 2, a kind of elevator light curtain, comprise projector 1 and receptor 2 that correspondence is located at elevator door both sides, this projector 1 and receptor 2 are all connected with light curtain circuit 3, multiple infrared trace light beam 7 is formed between this projector 1 and receptor 2, this light curtain circuit 3 is provided with shielding control circuit 4, this shielding control circuit 4 alternative masked segment infrared trace light beam 7.The utility model can according to the needs of applicable situation, mask a branch of or a few bundle infrared trace light beam 7 between projector 1 and receptor 2, the judgement making them not participate in infrared trace light beam whether to be blocked, even if a branch of or a few bundle infrared trace light beam 7 of i.e. conductively-closed is blocked, also door open command can not be sent by light curtain circuit 3 to apparatus for controlling elevator 6.Elevator light curtain can be avoided thus because the structural limitations of lift facility itself, and cannot normally run.As shown in Figure 2, need when the parts of installation function bottom of elevator door, two bundle infrared trace light beams 7 of projector 1 and receptor 2 bottom have been blocked, now can select to mask two bundle infrared trace light beams 7, namely the judgement allowing them not participate in infrared trace light beam whether to be blocked, thus avoid adding because of this functional component, and the situation of elevator light curtain cannot be used to occur.
Shielding control circuit 4 is connected with control button 5, and this control button 5 comprises forward select button 51, Low market efficiency button 52, acknowledge button 53 and cancel button 54.But can be changed by forward select button 51 and Low market efficiency button 52 and different infrared trace light beams 7 is selected, more corresponding infrared trace light beam 7 can be selected by acknowledge button 53 and cancel button 54.Namely can conveniently select to shield corresponding infrared trace light beam 7 by control button 5, thus to strengthen practicality of the present utility model further.
Control button 5 is located on the control desk of light curtain body, therefore when regulating the operating mode of elevator light curtain, can be convenient.
More than show and describe groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and specification sheets; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
