Description
Technical field
Crane travel anti-collision technical field is the utility model is related to, it is especially a kind of based on the large-scale of ultrasonic sensor
Gantry crane 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 more cranes or carrier and personnel's operation simultaneously, its working space is overlapped, easily collides, and causes the accident, therefore
Need a set of safe and reliable crane travel anti-collision protection system.Generally, limited in crane travelling gear end set machinery
Position device, carries out Anti-bumping protection, and when there is bar contact stopping means, spacing action, crane walking is slowed down or parking.Only
Parking could be triggered by touching physical obstacles, and when speed is high, impact is huge, easily causes 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 is put without triggering, causes to limit
Position failure.
At present, also have using crane travelling gear end set optical sensor light（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 passes
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.
Utility model content
A kind of large-sized gantry crane walking that the purpose of this utility model is in view of the shortcomings of the prior art and designed is super
Sound wave CAS, the CAS of sound and light alarm is formed using ultrasonic listening and console controller, control is simple, user
Just, cost-effective, anti-interference is done well, especially run into the weather such as mist, rain, snow also can normal work, incorporeity is spacing, and equipment exists
Physical impacts are not susceptible in induction region, induction region is space cone, and covering is wide, and blind area is few, just sends sound if necessary
Sound is alarmed, and can greatly reduce noise pollution, system run all right, reliable, and engineering cost is low, easy to maintenance, is risen for large-sized gantry
Heavy-duty machine security provides important leverage.
What the purpose of this utility model was realized in：A kind of large-sized gantry crane walking ultrasonic anti-collision system, its
Feature is that four ultrasonic sensors that the ultrasonic anti-collision system is connected by PLC main frames and acoustic-optic alarm form, institute
When stating ultrasonic sensor front obstacle is detected in detection range, the ultrasonic signal of receiving is converted into switching value letter
Number, and trigger PLC host computer controls crane and slow down 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 is run
Send audible alarm and flash-caution when direction is away from barrier 6m, and reduce the crane speed of service automatically, during away from barrier 3m
Send audible alarm and flash-caution and automatic stopping.
The utility model has simple in construction, good in anti-interference performance compared with prior art, stable, reliable, runs into
The weather such as mist, rain, snow also can normal work, without reflecting plate, induction region is space cone, and covering is wide, and blind area is few, no reality
Body is spacing, and equipment is not susceptible to physical impacts in induction region, just sends audible alarm if necessary, reduces noise pollution, property
Valency is than high, and control is simple, and 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 the utility model structure diagram.
Embodiment
Refering to accompanying drawing 1, the utility model is by PLC main frames（Crane mainframe controller）Four supersonic sensings of 2 connections
Device 1 and acoustic-optic alarm 3 form, and when the ultrasonic sensor 1 detects front obstacle in detection range, will connect
The ultrasonic signal received is converted into on-off model, and triggers PLC main frames 2 and control crane to slow down or stop, while acousto-optic report
Alarm device 3 sends 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 utility model is so installed and used：Ultrasonic wave is installed respectively in 4 ends of crane travelling gear
Sensor 1, its output signal access PLC main frames 2.The barrier occurred in front of crane runway is in the front of ultrasonic sensor 11
Exportable two groups of on-off models when in ~ 6m, PLC 2 first signals of main frame, sound and light alarm are triggered when there is barrier in 6 ~ 3m
Device 3 sends audible alarm and flash-caution；PLC 2 second signals of main frame, sound and light alarm are triggered when there is barrier in 3 ~ 1m
Device 3 sends audible alarm and flash-caution, and reduces the crane speed of service or automatic stopping automatically.
Control program logic of the present utility model is：In 1 ~ 6m of the front of ultrasonic sensor 1 during obstructing objects, ultrasonic wave passes
1 exportable 2 group of on-off model of sensor, i.e., trigger first signal when having barrier in 6 ~ 3m；Touched when having barrier in 3 ~ 1m
Send out second signal.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
After signal triggering, CAS sends sound and light alarm signal；After second signal triggering, CAS sends sound and light alarm signal
And the crane speed of service or automatic stopping are reduced automatically.
The trigger condition of anticollision protection system of the present utility model is：Cart run and ultrasonic sensor 1 it is spacing
Action（Generally set and switch to prescribe by normally closed point）.When above-mentioned condition all meet, if system if alarm mode drivers' cab report
Alert, if system, cart automatically switches to low speed if protected mode（It is usually arranged as 5HZ）, and drivers' cab is alarmed, system
Alarm mode and protected mode are switched over by the selecting switch of drivers' cab.When crane traffic direction does not have barrier, sound
Light alarm device 3 only flashes alarm signal and voiceless sound is alarmed；When crane traffic direction has barrier, sound and light alarm
Device 3 sends sound and light alarm signal, and reduces the crane speed of service or automatic stopping automatically（Slow down during away from barrier 20m, 3m
When stop）.
Simply the utility model is described further above, and is not used to limit this patent, it is all for the utility model etc.
Effect is implemented, and is intended to be limited solely by within the right of the utility model patent.
