Description
Technical field
It the utility model is related to the safety device in a kind of factory, the safety dress of especially a kind of elevator of car door
Put.
Background technology
Elevator of car door is typically employed on general assembly pipeline, realizes the transhipment conveying function of car door.
Lift typically belongs to relatively large equipment, and in rise and fall campaign, speed ratio is very fast, and particularly car door lifts
Machine needs personnel to be operated into lifting region, once the personnel of discovery, which are strayed into lifting region, needs the fortune of system for stopping elevators immediately
Make, with protection staff safety.
The content of the invention
The purpose of this utility model is to provide a kind of safety device of elevator of car door, can not existed in elevator of car door
During home, personnel or object triggering grating are detected the presence of, stops car door immediately if the personnel of discovery are strayed into lifting region
Lift acts, real-time guard personal safety；The technical solution adopted in the utility model is：
A kind of safety device of elevator of car door, including safety guard net, two proximity switches, grating, failure safe module,
PLC；
Safety guard net be arranged on elevator of car door lifting region around, elevator of car door drive automobile door sling rise or under
Drop；Grating is arranged on automobile door sling side, on the inside of safety guard net；Opening is provided with the safety guard net of that side of grating；
Proximity switch is fixed on elevator of car door bottom side；
Two proximity switches are directly connected to the control loop of grating；The output end connecting fault security module of grating, failure
Security module connects PLC by fieldbus.
Further, failure safe module connects PLC by profinet buses.
More preferably, the setting height(from bottom) of proximity switch is less than human height.
The utility model has the advantage of：The safety device is reliable and stable, and safe class is high；Direct hardware connection, exempts
Many programing works；Response time is fast, real-time guard personal safety.
Brief description of the drawings
Fig. 1 is structure composition schematic diagram of the present utility model.
Fig. 2 is electrical schematic diagram of the present utility model.
Embodiment
With reference to specific drawings and examples, the utility model is described in further detail.
As depicted in figs. 1 and 2, the safety device of elevator of car door, including safety guard net 1, two proximity switch 3, grating
4th, failure safe module 6, PLC 7；
Safety guard net 1 is arranged on around the lifting region of elevator of car door 2, and elevator of car door 2 drives automobile door sling 5 to rise
Or decline；Grating 4 is arranged on the side of automobile door sling 5, positioned at the inner side of safety guard net 1；On the safety guard net 1 of that side of grating 4
Provided with opening, passed in and out for personnel or object；
Proximity switch 3 is fixed on the bottom side of elevator of car door 2；Elevator of car door 2 drops to security bit with automobile door sling 5
Proximity switch 3 is triggered when putting；It is preferred that the setting height(from bottom) of proximity switch 3 is less than human height；
As shown in Fig. 2 two proximity switches 3 are directly connected to the control loop of grating 4；The output end connecting fault of grating 4
Security module 6, failure safe module 6 connect PLC 7 by profinet buses；Wherein, failure safe module 6 uses
Siemens ET200s；
Operation principle of the present utility model is as follows：
Elevator of car door 2 drops to ground with automobile door sling 5（Home）, proximity switch 3 detects elevator of car door 2
Position, grating 4 is fed back to, self function of shielding of grating 4 starts, and grating 4 exports shielding indicator lamp to operating personnel, it is allowed to people
Member normally enters, while exports normal information to failure safe module 6.
When elevator of car door 2 with automobile door sling 5 not in home when, for example elevator of car door 2 rises to certain altitude,
Proximity switch 3 does not trigger, 4 unshielded function of grating, now has personnel or object to enter in safety guard net 1, triggers grating 4,
The output abnormality information of grating 4 transmits this information to PLC to failure safe module 6, failure safe module 6 by profinet buses
Controller 7, after PLC 7 receives this information, stop elevator of car door 2 immediately and act, while sound and light alarm.
