Abstract
This utility model is that bucket wheel machine feeding revolution border judges control system, including pressure transducer, signals collecting distant station and unit controller, pressure transducer connects signals collecting distant station through signal cable, and signals collecting distant station connects unit controller through communication cable；Method comprises the step of: the first step: pressure transducer obtains reclaimer bucket wheel hydraulic motor internal pressure；Second step: signals collecting distant station obtains pressure data, and pressure data sends to unit controller；3rd step: pressure data is converted into force value by unit controller, contrasts with force value set in advance, and be made whether to arrive the judgement on actual windrow border.This utility model can make that reclaimer is safe and accurate, carry out unmanned automatic job efficiently, decreases the idle stroke in reclaimer operation process simultaneously, improves feeding efficiency.
Description
Technical field
This utility model relates to bucket wheel machine feeding automation field, particularly relates to bucket wheel machine feeding revolution border and sentences
Disconnected control system.
Background technology
Along with harbour bulk cargo terminals production management level require improve constantly, high efficiency, automatization, unmanned,
Intellectuality has become as harbour bulk cargo terminals production control system development trend.In bulk cargo terminals production process, from
Dynamic feeding and automatic stockpiling control operation and have played an important role.But, existing nobody automatically controls
The factors such as it is low that operation also creates feeding efficiency, and feeding boundary control accuracy is low.Therefore, by reclaimer bucket
Wheel pressure monitoring automatic material taking be turned back to the control method on limit provide more accurately feeding border to site.Enter
And, improve the Accuracy and high efficiency of unmanned operation.
Summary of the invention
This utility model provides bucket wheel machine feeding revolution border to judge control system, including pressure transducer, signal
Gathering distant station and unit controller, pressure transducer connects signals collecting distant station through signal cable, and signal is adopted
Collection distant station connects unit controller through communication cable；
Described pressure transducer is arranged on reclaimer bucket wheel hydraulic motor, and described signals collecting distant station is arranged on
On reclaimer cantilever, pressure transducer is for detecting the pressure data of reclaimer bucket wheel hydraulic motor, signals collecting
Distant station is used for obtaining pressure data, and pressure data sends to unit controller, and unit controller is by pressure
Data are converted into force value, contrast with force value set in advance, and be made whether to arrive actual windrow
The judgement on border.
Further, described pressure transducer is hydrostatic sensor.
Further, described unit controller is unit PLC.
The beneficial effects of the utility model are: the data that this utility model measures feedback by pressure transducer are believed
Breath, calculates actual pressure value according to scale operation, the most right with the force value set corresponding to feeding instantaneous flow
Than judging that revolution feeding, whether to limit, and then makes that reclaimer is safe and accurate, carry out unmanned automatic job efficiently,
Decrease the idle stroke in reclaimer operation process simultaneously, improve feeding efficiency.

Detailed description of the invention
It is described in detail referring to the drawings below with reference to embodiment of the present utility model.
Bucket wheel machine feeding revolution border judges control system, including pressure transducer 1, signals collecting distant station 3
With unit controller 5, pressure transducer 1 connects signals collecting distant station 3, signals collecting through signal cable 2
Distant station 3 connects unit controller 5 through communication cable 4；
Described pressure transducer 1 is arranged on reclaimer bucket wheel hydraulic motor 6, described signals collecting distant station 3
Being arranged on reclaimer cantilever 7, pressure transducer 1 is for detecting the number pressure of reclaimer bucket wheel hydraulic motor 6
According to, signals collecting distant station 3 is used for obtaining pressure data, and pressure data sends to unit controller 5,
Pressure data is converted into force value by unit controller 5, contrasts with force value set in advance, and makes
The most arrive the judgement on actual windrow border.
Further, described pressure transducer 1 is hydrostatic sensor.
Further, described unit controller 5 is unit PLC.
The computing flow process of unit controller 5 is as follows:
Return data according to pressure transducer and calculate reclaimer bucket wheel hydraulic motor internal pressure value, reclaimer bucket
Wheel hydraulic motor internal pressure value is set to A, presets force value corresponding to feeding amount and is set to B；According to currently
It is a that feeding floor height does the variable that inverse proportional operation draws, goes out by inverse proportional operation with the speed of gyration ratio of revolution feeding
Percentage ratio be b；
If A is more than B*a%, and adds up to reach time T1 more than B*a%, now assert that bucket wheel is current the most
Start a cut through stockpile and start normal feeding；
On the premise of normal feeding, A is less than B*b%, if the time that accumulation is less than B*b% is not up to T2,
Recover again to the A state more than or equal to B*b%, it is judged that not arriving actual stockpile border, continuation is in logic
Middle supervision judges；Reach T2 when the accumulation time less than B*b%, i.e. determine that current reclaiming process has arrived reality
The border of stockpile.
Described bucket wheel machine feeding revolution border judges that control system can also detect feeding amount.
The above is only preferred implementation of the present utility model, it is noted that general for the art
For logical technical staff, on the premise of without departing from this utility model principle, it is also possible to make some improvement and profit
Decorations, these improvements and modifications also should be regarded as protection domain of the present utility model.
