Abstract
A pre-alarm system for mistake stepping empty elevator well, and consists of a lead, a red caution light, a buzzer, a frequent open switch, a frequent close switch and etc. Red caution light is connected with the buzzer by the lead, then in turn and series connected with the frequent open switch, the frequent close switch and etc. The two sides are connected with the positive electrode and cathode. The frequent open is connected with the floor door. The condition is cut when the layer door is normally closed. The condition is close when the layer door is open. The frequent open is linking with car. When the car is in the open door section, the car is in the cut condition. The car is in the close condition when the car is not in open door section. Two of the switch is close when the floor door is open and the car is not in the floor, with the circuitry is connecting, the red caution light shines, the buzzer sounds, which is exert the caution effect. The benefit of the utility model is that the utility model is not affect the normal use of the elevator and also can avoid when the car of the elevator is not on the floor, people is mistake to come in the elevator well path and occur the fall accident.
Description
Affiliated technical field
The utility model relates to a kind of elevator safety technology, and particularly a kind of anti-elevator hoistways that is strayed into is stepped on sky and fallen forewarn system.
Background technology
For preventing that being strayed into elevator hoistways steps on the sky fallen accident, elevator universal demand elevator car door system possesses layer door, the dynamo-electric interlock of gate interlock both at home and abroad, when that is to say that car is not within This floor opens the door district's scope, external force need not be special key can not open layer door, its objective is to prevent and step on the sky fallen accident.However, damage, open layer door the no cautionary measure of maintenance and pedestrian when being strayed into, having the people to open situation generation such as layer door by force because of carelessness, still can be strayed into elevator hoistways and step on the sky fallen accident when control circuit fault, door lock.It is very serious that in a single day consequence takes place this class accident, is reported in media frequently.It is reported that elevator standard and lift product lack other early warning measure except the gate interlock interlock at present.
Summary of the invention
In order to remedy above deficiency, the utility model provides a kind of anti-elevator hoistways that is strayed into to step on sky and fall forewarn system, adopts simple electric wiring and elevator car door system to do dynamo-electric logic and is connected, and utilizes the generation of sound and light program early warning similar accident.
For achieving the above object, the utility model adopts following technical scheme:
Design a kind of electric wiring, mainly comprise lead, red Warning light, buzzer phone, normal open switch, normally closed switch etc.Red Warning light, buzzer phone are connected in parallel, and connect successively with normal open switch, normally closed switch, and two ends are the power connection both positive and negative polarity respectively.Normal open switch is moving with the layer couplet on the door, and layer door is in off-state when normally closing, and layer door is in closure state when opening; Normally closed switch and car interlock, car are in off-state when opening the door the district, car is not in closure state when opening the door the district.Have only when layer door opens that car is not at This floor simultaneously two switches all closed, circuit is connected, and red Warning light is bright, and buzzer phone rings, the performance warning function.The beneficial effects of the utility model are to utilize human eye to experience red light and arouse warning function and the sound suggesting effect that danger closes on and avoid following type accident: (1) is when lift car during not at This floor, because of improper former thereby opened layer door, riding elevator personnel do not examine and enter the elevator hoistways that does not have elevator; (2) open a no cautionary measure of layer door maintenance or a cautionary measure imperfection, perhaps riding personnel fail to notice and open the door inspecting state and be strayed into the hoistway that does not have elevator.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model schematic circuit.
Among the figure: 1. normally closed switch, 2. normal open switch, 3. red Warning light, 4. lead, 5. buzzer phone.
The specific embodiment
With reference to accompanying drawing,, to connect with normally closed switch 1, normal open switch 2 successively again red Warning light 3 and buzzer phone 5 parallel connections with lead, two ends are the power connection positive and negative polarities respectively.Normal open switch 2 is moving with the layer couplet on the door, when layer door normally closed, is in off-state, and layer door is in closure state when opening; Normally closed switch 1 and car interlock, car are in off-state when opening the door the district, car is not in closure state when opening the door the district.
Have only when car is not opened when door layer normally closed switch 1 at This floor, normal open switch 2 is all closed, circuit is connected, and red Warning light 3 is bright, and buzzer phone 5 sound are brought into play warning function.When riding personnel in the process that layer door opened, perhaps go to the layer of having opened and experience red light and hear caution sound in front of the door suddenly, can enhance your vigilance, arouse attention the danger of finding and avoiding facing.
