Description
Technical field
The present invention relates to crane travel anti-collision technical field, especially a kind of large-sized gantry based on ultrasonic sensor
Crane travel anti-collision system.
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 ultrasonic wave that the purpose of the present invention is in view of the shortcomings of the prior art and designed
CAS, the CAS of sound and light alarm is constituted using ultrasonic listening and console controller, and control is simple, easy to use,
Cost performance is high, and 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 being felt
Answer and physical impacts are not susceptible in region, induction region is space cone, covering is wide, and blind area is few, and sound is just sent if necessary
Alarm, can greatly reduce noise pollution, system run all right, reliable, and engineering cost is low, easy to maintenance, is large-sized gantry lifting
Machine security provides important leverage.
The object of the present invention is achieved like this：A kind of large-sized gantry crane walking ultrasonic anti-collision system, its feature
It is that four ultrasonic sensors and acoustic-optic alarm that the ultrasonic anti-collision system is connected by PLC main frames are constituted, it is described super
When sonic sensor detects front obstacle in detection range, the ultrasonic signal of receiving is converted into on-off model,
And trigger the deceleration of PLC host computer controls crane or stop, while acoustic-optic alarm sends audible alarm and flash-caution.
Exportable two groups of on-off models when the ultrasonic sensor detects obstructing objects in 1 ~ 6m of front, as 6 ~ 3m
PLC first signal of main frame is triggered when inside having barrier, acoustic-optic alarm sends audible alarm and flash-caution；When in 3 ~ 1m
PLC second signal of main frame is triggered when having barrier, acoustic-optic alarm sends audible alarm and flash-caution, and reduces automatically
The crane speed of service or automatic stopping.
The acoustic-optic alarm flashes warning when crane traffic direction does not have barrier, when crane operation
Audible alarm and flash-caution are sent when direction is away from barrier 6m, and reduces the crane speed of service automatically, during away from barrier 3m
Send audible alarm and flash-caution and 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 four ultrasonic sensors 1 with
And acoustic-optic alarm 3 is constituted, when the ultrasonic sensor 1 detects front obstacle in detection range, by receiving
Ultrasonic signal is converted into on-off model, and triggers the control crane deceleration of PLC main frames 2 or stop, while sound and light alarm is filled
Put 3 and send audible alarm and flash-caution.
The ultrasonic sensor 1 is using UC6000-30GM-2EP-IO-V15 series；The main control of the PLC main frames 2
Device uses S7-300-315-DP；The acoustic-optic alarm 3 uses BC-8A, and its warning lamp is ABC-9.
The present invention is so to install and use：Supersonic sensing is respectively mounted in 4 ends of crane travelling gear
Device 1, its output signal access PLC main frames 2.The barrier occurred in front of crane runway is in 1 ~ 6m of the front of ultrasonic sensor 1
Exportable two groups of on-off models when interior, PLC 2 first signals of main frame, sound and light alarm dress are triggered when there is barrier in 6 ~ 3m
Put 3 and send audible alarm and flash-caution；PLC 2 second signals of main frame, sound and light alarm dress are triggered when there is barrier in 3 ~ 1m
Put 3 and send audible alarm and flash-caution, and the reduction crane speed of service or automatic stopping automatically.
The present invention control program logic be：In 1 ~ 6m of the front of ultrasonic sensor 1 during obstructing objects, ultrasonic sensor
First signal is triggered when having barrier in 1 exportable 2 groups of on-off models, i.e. 6 ~ 3m；Is triggered when having barrier in 3 ~ 1m
Two signals.This group of signal can be equal to the spacing switching signal of standard, and it inputs PLC main frames 2 and handled, its first signal
After triggering, CAS sends sound and light alarm signal；After second signal triggering, CAS sends sound and light alarm signal simultaneously certainly
The dynamic reduction crane speed of service or automatic stopping.
The trigger condition of anticollision protection system of the present invention is：Cart operation and the spacing action of ultrasonic sensor 1
（Generally set and switch to prescribe by normally closed point）.When above-mentioned condition is all met, if system, drivers' cab is alarmed if alarm mode, if
In protected mode, then cart automatically switches to low speed to system（It is usually arranged as 5HZ）, and drivers' cab alarm, the alarm mould of system
Formula and protected mode are switched over by the selecting switch of drivers' cab.When crane traffic direction does not have barrier, sound and light alarm
Device 3 only flashes alarm signal and voiceless sound is alarmed；When crane traffic direction has barrier, acoustic-optic alarm 3
Send sound and light alarm signal, and the reduction crane speed of service or automatic stopping automatically（Slow down during away from barrier 20m, stop during 3m
Car）.
Simply the present 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.
