Abstract
The invention discloses a safety pre-warning device used when an elevator is close to a landing door. The safety pre-warning device is composed of a door interlocking switch (1), one or more distance sensors (2), a controller (3) and a sound-light warning device (4). The distance sensors (2) are installed on the elevator landing door, and the controller (3) controls the sound-light warning device (4) to work. The pre-warning device is simple in structure and convenient to install, and can give out an alarm to prompt elevator passengers to retreat to keep away from the elevator landing door by a certain safety distance when the elevator passengers are too close to the elevator landing door, and the situation that due to the fact that an elevator landing door is opened accidentally, an elevator slips, and casualty accidents are caused can be effectively avoided.
Description
Technical field
The present invention relates to a kind of safety early warning device, particularly a kind of safety and take the nearly layer door prior-warning device of elevator of elevator
Background technology
Development along with society, the application of elevator is more and more extensive, and old elevator also increases 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 significantly high, 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 not 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, technical scheme is as follows:
The invention discloses a kind of nearly layer door safety early warning device of elevator, 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.
Present configuration is simple, easy for installation, when boarding personnel distance layer door is crossed near, can send sound and light alarm, and 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 the fundamental diagram of the present invention
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 signal is processed, 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
Below in conjunction with drawings and Examples, the present invention is further illustrated, but is not intended as the foundation to present invention restriction.
Embodiment: a kind of nearly layer door safety early warning device of elevator, 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.
Operation 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.
