Description
Technical field
The present invention relates to crane travel anti-collision technical field, especially a kind of large-sized gantry based on microwave remote sensor rises
Heavy-duty machine walking CAS.
Background technology
Large-sized gantry crane is the important tool of production of shipyard or harbour, harbour, and it typically walks along trapped orbit,
Track length is in more than 100m.In recent years, density of equipment increases year by year in factory, in the same area of crane runway often
There are many cranes or carrier and personnel's operation simultaneously, its working space is overlapped, easily collides, causes the accident, therefore
Need a set of safe and reliable crane travel anti-collision protection system.Generally, machinery limit is set in crane travelling gear end
Position device, carries out Anti-bumping protection, when there is bar contact stopping means, spacing action, and crane walking is slowed down or stopped.Only
Parking could be triggered by touching physical obstacles, when speed is high, impacted huge, easily caused the accident.Other mechanical position limitation
Device is only a single point triggering, has a large amount of blind areas, for space object, it is entirely possible to which staggering, this puts and without triggering, causes limit
Position failure.
At present, also have and optical sensor light is set using crane travelling gear end（Ordinary ray or laser）To lifting
The walking of machine carries out Anti-bumping protection.Optical sensor usually requires reflecting plate, and the only barrier of reflecting plate is just effective, and optics is passed
The detection zone of sensor also triggers for a single point, there is a large amount of blind areas.In addition in outdoor area, the weather such as mist, rain, snow, light are run into
Sensor is invalid or reports by mistake, causes shielding failure.Especially, the cost of laser sensor is the decades of times of other sensors.Separately
Outside, in order to prevent crane strikes obstacles in the process of walking, acoustic-optic alarm generally is set in walking mechanism end portion,
When crane is run, alarm sends up to 90~100dB alarm song, causes huge noise pollution, and personnel exist for a long time
In this operating environment, auditory fatigue and impaired hearing are caused.
The content of the invention
A kind of large-sized gantry crane walking microwave that the purpose of the present invention is in view of the shortcomings of the prior art and designed is prevented
System is hit, the CAS of sound and light alarm is constituted using microwave sounding and master controller, control is simple, easy to use, cost performance
Height, anti-interference is done well, especially run into the weather such as mist, rain, snow also can normal work, incorporeity is spacing, and equipment is in induction region
Physical impacts are inside not susceptible to, induction region is space cone, and covering is wide, and blind area is few, and audible alarm is just sent if necessary, can
Greatly reduce noise pollution, system run all right, reliable, engineering cost is low, easy to maintenance, is large-sized gantry crane security
Important leverage is provided.
The object of the present invention is achieved like this：A kind of large-sized gantry crane walking microwave CAS, is characterized in
Two microwave sounding unit, MSUs and acoustic-optic alarm that the microwave CAS is connected by PLC main frames are constituted, the microwave sounding
Two microwave remote sensors that device is connected by control unit are constituted；The microwave remote sensor detects preceding object in detection range
During thing, the electromagnetic radio-frequency that microwave remote sensor receives is converted into on-off model by control unit, and triggers PLC host computer controls
Crane slows down or stopped, while acoustic-optic alarm sends audible alarm and flash-caution.
The microwave remote sensor detect front 0.2 ~ 20m in obstructing objects when exportable 2 groups of on-off models, 20m ~
PLC first signal of main frame is triggered when having barrier in 5m, CAS sends sound and light alarm signal；There is barrier in 5m ~ 1.8m
PLC second signal of main frame is triggered when hindering thing, CAS sends sound and light alarm signal and reduces the crane speed of service automatically
Or automatic stopping.
The acoustic-optic alarm only flashes alarm signal when crane traffic direction does not have barrier, works as lifting
Sound and light alarm signal is sent when machine traffic direction is away from barrier 20m, and reduces the crane speed of service automatically, during away from barrier 3m
Automatic stopping.
The present invention compared with prior art have simple in construction, good in anti-interference performance, it is stable, reliable, run into mist,
The weather such as rain, snow also can normal work, without reflecting plate, induction region is space cone, and covering is wide, and blind area is few, incorporeity
Spacing, equipment is not susceptible to physical impacts in induction region, and audible alarm is just sent if necessary, reduces noise pollution, sexual valence
Than high, control simply, engineering cost is low, easy to maintenance, and important leverage is provided for large-sized gantry crane security.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Embodiment
Refering to accompanying drawing 1, the present invention is by PLC main frames（Crane mainframe controller）2 connection two microwave sounding unit, MSUs 1 with
And acoustic-optic alarm 3 is constituted, two microwave remote sensors 11 that the microwave sounding unit, MSU 1 is connected by control unit 12 are constituted；Institute
When stating microwave remote sensor 11 and detecting front obstacle in detection range, the electricity that control unit 12 receives microwave remote sensor 11
Magnetic radiofrequency signal is converted into on-off model, and triggers the control crane deceleration of crane mainframe controller 2 or stop, while sound
Light alarm device 3 sends audible alarm and flash-caution.The microwave sounding unit, MSU 1 is using RAS 400-7S1 series, its microwave
Tranmitting frequency is 24.125GHz；The master controller of the PLC main frames 2 uses S7-300-315-DP；The acoustic-optic alarm 3
Using BC-8A, its warning lamp is ABC-9.
The present invention is so to install and use：Two sets of microwave sounding unit, MSUs 1 are arranged on crane travelling gear, its
Four end difference one microwave remote sensors 11 of each installation, the output switch amount of control unit 12 letter of the microwave sounding unit, MSU 1
Number crane mainframe controller 2 is arrived, when the barrier occurred in front of the crane runway is in the detection range of microwave remote sensor 11
Signal is triggered, and the control crane of crane mainframe controller 2 slows down or stopped, while controlling acoustic-optic alarm 3 to send sound
Alarm.
The present invention control program logic be：In 0.2 ~ 20m of the front of microwave remote sensor 11 during obstructing objects, microwave remote sensor
11 exportable 2 groups of on-off models；Trigger when having barrier in first signal, 5m ~ 1.8m and touch when having barrier in 20m ~ 5m
Second signal is sent out, this group of signal can be equal to the spacing switching signal of standard, and input PLC main frames 2 are handled, its first letter
Warning system sends sound and light alarm signal after number triggering, and warning system sends sound and light alarm signal after second signal triggering, and
The automatic reduction crane speed of service or automatic stopping.
The present invention trigger condition be：Cart operation and the spacing action of microwave remote sensor 11（Generally set by normally closed
Point switchs to prescribe）.When above-mentioned condition is all met, if system, drivers' cab is alarmed if alarm mode, if system is in protected mode
Then cart automatically switches to low speed（It is usually arranged as 5HZ）Or parking, and drivers' cab alarm, the alarm mode of system and protection
Pattern is switched over by the selecting switch of drivers' cab.When crane traffic direction does not have barrier, acoustic-optic alarm 3 is only sent out
Go out flashing light alarm signal and voiceless sound is alarmed, when crane traffic direction has barrier, acoustic-optic alarm 3 sends acousto-optic report
Alert signal, and the reduction crane speed of service or automatic stopping automatically（Slow down during away from barrier 20m, stopped during 3m）.
Simply the invention will be further described above, and is not used to limit this patent, and all is equivalence enforcement of the present invention,
Within the right that patent of the present invention should be contained in.
