Abstract
The utility model discloses a nearly layer door safety precaution device of elevator, by gate interlock switch (1), distance sensor (2), controller (3), audible and visual alarm (4) are constituteed. The quantity of distance sensor (2) is more than one, installs on the door of elevator layer, through controller (3) control audible and visual alarm (4) work. The utility model discloses simple structure, simple to operate when taking advantage of terraced personnel to cross when near being close to elevator layer door, can send the warning, and the suggestion is taken advantage of terraced personnel to retreat to keep certain safe distance with elevator layer door, can effectively prevent to open elevator swift current ladder and the emergence of the casualty accident that arouses because of elevator layer door accident.
Description
Technical field
This utility model relates to a kind of safety early warning device, and a kind of safety takes the elevator nearly layer door prior-warning device of elevator
Background technology
Development along with society, the application of elevator is more and more extensive, and old elevator increases the most therewith, elevator repair and maintenance quality is uneven, elevator accident also happens occasionally, the casualty accident of falling that particularly elevator door unnormal unlocking causes, and elevator brake is ineffective causes the terraced shearing accident occurred of slipping, in elevator accident, proportion is the highest, the personal safety of serious threat boarding personnel.
Boarding personnel are accustomed to lift stand layer doorway, and layer door strides into once opening a step, wait discovery lift car in place or car moves and cannot make a response, and then elevator safety accident occurs.
Summary of the invention
For solving the problems referred to above, it is proposed that a kind of safety early warning device, remind boarding personnel to keep certain distance when waiting ladder with elevator door, wait lift car put in place come to a complete stop after enter back into car, it is ensured that boarding safety.
For reaching above-mentioned purpose, the technical solution of the utility model is as follows:
The utility model discloses a kind of elevator nearly layer door safety early warning device, by door interlock switch (1), range sensor (2), controller (3), acoustic-optic alarm (4) forms.Door interlock switch (1) is installed on the both sides of door, elevator door closes, door interlock switch (1) is connected, range sensor (2) is started working, the quantity of range sensor (2) be one and more than, it is installed on elevator door, the probe face of range sensor (2) is towards hall, for sending and receiving signal, signal is processed by controller (3), calculate the distance of boarding personnel and elevator door, when the distance that distance when boarding personnel wait ladder exceedes default found out by range sensor (2), system will be passed through acoustic-optic alarm (4) and send sound and light alarm, prompting boarding personnel retreat and keep certain safe distance to wait ladder with elevator door.
This utility model simple in construction, easy for installation, when boarding personnel distance layer door is crossed near, sound and light alarm can be sent, prompting boarding personnel wait ladder at safe distance, can effectively prevent because elevator door is surprisingly opened, the generation of the casualty accident that elevator slips ladder and causes.
Accompanying drawing explanation
Fig. 1 is fundamental diagram of the present utility model
Being labeled as of accompanying drawing: 1 is door interlock switch, is used for switching on and off prior-warning device
2 is range sensor, is used for sending and receiving signal
3 is controller, for processing signal, calculates the distance of boarding personnel and elevator door, controls acoustic-optic alarm action
4 is acoustic-optic alarm, is used for sending sound and light alarm signal
Detailed description of the invention
With embodiment, this utility model is further described below in conjunction with the accompanying drawings, but is not intended as the foundation that this utility model is limited.
Embodiment: a kind of elevator nearly layer door safety early warning device, as it is shown in figure 1, include door interlock switch (1), door interlock switch (1) successively with range sensor (2), controller (3), acoustic-optic alarm (4) connects.
nullOperation principle: door interlock switch (1) is installed on the both sides of door，Elevator door closes，Door interlock switch (1) is connected，Range sensor (2) is started working，The quantity of range sensor (2) is more than one，It is installed on elevator door，The probe face of range sensor (2) is towards hall，For sending and receiving signal，Signal is processed by controller (3)，Calculate the distance of boarding personnel and elevator door，When the distance that distance when boarding personnel wait ladder exceedes default found out by range sensor (2)，System will be passed through acoustic-optic alarm (4) and send sound and light alarm，Prompting boarding personnel retreat and keep certain safe distance to wait ladder with elevator door，Lift car puts in place flat bed，Elevator door opening，Door interlock switch (1) disconnects，Prior-warning device quits work，Boarding personnel are freely accessible to lift car.
