Specific implementation mode
In the present invention, in the absence of explanation to the contrary, the noun of locality used such as " top, bottom, left and right " is usual
Refer to top, bottom shown in refer to the attached drawing, left and right;" inside and outside " refers to the inside and outside of the profile relative to each component itself.
As shown in Figure 1 and Figure 2, a kind of production line vehicle door status detection device, including supporting mechanism 1, testing agency 3, control
Platform 2 and attention device 4, testing agency 3 are mounted on supporting mechanism 1, the input of the output end and control platform 2 of testing agency 3
End electrical connection, the output end of control platform 2 are electrically connected with attention device 4, and the output end of control platform 2 is also electrically connected with stretched wire suspender 5
It connects.In the production line in vehicle body operational process, testing agency 3 detects whether vehicle vehicle door status closes, if testing agency 3 is detected
To there is car door to be not turned off, control platform 2 is sent a signal to, control platform 2 sends out instruction control control stretched wire suspender 5 and is parked in this
Station, while control platform 2 sends out instruction control attention device 4 and works, and prompts staff to shut car door, to prevent safety
Hidden danger.
Above-mentioned control platform 2 is production line switch board (control platform 2 being previously mentioned below is production line switch board), raw
Producing line switch board is equipped with PLC controller, and PLC controller controls other components according to 2 received signal of the control platform
Work.Above-mentioned testing agency 3 is gentle including the first detection detection of cylinder 31, second cylinder 32, cylinder operation trigger switch 33
Cylinder retracts trigger switch 34, and cylinder operation trigger switch 33 and cylinder retract the signal output end and control platform of trigger switch 34
2 signal input part connection, control platform 2 are electrically connected with the first detection cylinder 31 and the second detection cylinder 32.Production line
When normal operation, vehicle is placed on stretched wire suspender 5 and is moved with production line, when the suspender arm 51 of stretched wire suspender 5 reaches cylinder work
When making the position at 33 place of trigger switch, the location information of the suspender arm 51 of the sensor detection of cylinder operation trigger switch 33,
And control platform 2 is sent that information to, the PLC controller of control platform 2 is according to received signal triggering the first detection cylinder
31 and second detect the stretching of cylinder 32;Stretched wire suspender 5 continues to move, when stretched wire suspender 5 suspender arm 51 reach cylinder retract it is tactile
When sending out the position at 34 place of switch, cylinder retracts the location information of the suspender arm 51 of the sensor detection of trigger switch 34, and will
The information is sent to control platform 2, and the PLC controller of control platform 2 is according to received signal triggering the first detection 31 He of cylinder
Second detection cylinder 32 is retracted, and is terminated to the vehicle door status detection of the vehicle, is continued the detection of next vehicle.
First detection cylinder 31 is equipped with the first travel switch 35 of detection vehicle door status, and the second detection cylinder 32 is equipped with detection
The signal that second travel switch 36 of vehicle door status, the first travel switch 35 and the second travel switch 36 detect sends control to
Platform 2 processed.In the present invention, it using the headstock of vehicle on production line as reference direction, stands towards headstock direction, the first inspection
It surveys cylinder 31 and the first Cheng Kaiguan 35 is mounted on the left side of vehicle body 7 for detecting the state of left side car door 71, the second detection cylinder
32 and the and the right that Cheng Kaiguan 36 is mounted on vehicle body 7 is used for detecting the state of right side car door 72.When the first detection 31 He of cylinder
After second detection cylinder 32 stretches out, the distance of the first travel switch 35 and the second travel switch 36 to vehicle car door is 10~
30mm then illustrates that left side car door 71 exists for the state closed if car door and the first travel switch 35 are touched, if car door with
Second travel switch 36 is touched, then illustrates that right side car door 72 exists for the state closed;First travel switch 35 and the second stroke
Switch 36 sends the signal of the vehicle door status detected to control platform 2, and the PLC controller of control platform 2 is according to receiving
Signal judge, simply by the presence of touching phenomenon, then send out instruction:Make 5 this station of stop out of service of stretched wire suspender, warns simultaneously
After the staff of this station confirms that all car doors are in closed state, it is flat to press control by 4 alarm staff of device
Reset button on platform 2, stretched wire suspender 5 can restore normal operation.If car door and the first travel switch 35 and the second stroke
Switch 36 is to touch, then control platform 2 is given tacit consent to car door and is closed, and can enter next station.

Preferably, the attention device 4 in the utility model be audible-visual annunciator, audible-visual annunciator be mounted on production line it is eye-catching
Position, aspect staff can see, be preferably mounted to vehicle detection station.
The course of work of the utility model:
Vehicle moves on stretched wire suspender 5 with production line, when cylinder operation trigger switch 33 detects hanging for stretched wire suspender 5
When having arm 51, production line switch board (i.e. control platform 2) is sent a signal to, the PLC controller of production line switch board is according to reception
Signal triggering first detection cylinder 31 and second detect cylinder 32 quickly stretch out;Stretched wire suspender 5 continues to run with while being arranged
The first travel switch 35 and the second travel switch 36 on the first detection detection cylinder 32 of cylinder 31 and second start to car door shape
State is detected, if car door has touched the first travel switch 35 and/or the second travel switch 36, is illustrated that car door exists and is not closed
The state closed, the first travel switch 35 and the second travel switch 36 send the signal of the vehicle door status detected to production line traffic control
The PLC controller of cabinet processed, production line switch board judges according to the signal received, simply by the presence of touching phenomenon, then sends out instruction:
Make 5 this station of stop out of service of stretched wire suspender, while audible-visual annunciator alarm staff, the staff of this station
After confirming that all car doors are in closed state, the reset button on production line switch board is pressed, stretched wire suspender 5 can restore
Normal operation enters next station.If it is to touch the second travel switch 36 that car door, which does not touch the first travel switch 35, yet, give birth to
Producing line switch board is defaulted as car door and is closed, and stretched wire suspender 5 continues to run with.Trigger switch 34 is retracted when cylinder to detect
When the suspender arm 51 of stretched wire suspender 5, production line switch board is sent a signal to, the PLC controller of production line switch board is according to reception
Signal triggering the first detection cylinder 31 and second detect cylinder 32 and quickly retract, the detection of the vehicle door status of the vehicle is terminated, after
The continuous detection for carrying out next vehicle.
