Description
Technical field
The utility model is related to a kind of quality control technology, more particularly to a kind of hydraulic spanner operation automatic inspection system.
Background technology
At present, when wind power generating set is installed at the scene, big component installation is all the high-strength spiral shell by a large amount of different sizes
Bolt is fixedly connected.As high-strength bolt fastening tool, hydraulic spanner extensive use in an installation.In installing at the scene, to liquid
Pressure spanner fastening has stringent technological requirement, and hydraulic spanner provides power by hydraulic pump, and hydraulic pump delivery outlet generally connects pressure
Table, convenient in work progress, operating personnel monitor.After installation, product judges whether product is qualified by sampling observation mode.But due to
Artificial origin, wind turbine manufacture, installation, maintenance torque to surpass torque there are high-strength bolt in the process, owe torque phenomenon, directly form
The hidden danger of product quality.The quality guarantee of high-strength bolt and be installed in place it is particularly significant to wind power generating set product quality, but
If installing monitored over time, and with a large amount of cost, and influence manufacturing schedule.
Invention content
The utility model be for high-strength bolt installation whether in place to wind power generating set qualitative effects the problem of, propose
A kind of hydraulic spanner operation automatic inspection system, high-strength bolt torque operation process can trace；Torque job state is visual
Change；Torque operation process system fool proof；Tool state exception automatic alarm；Tool lifecycle management.
The technical solution of the utility model is：A kind of hydraulic spanner operation automatic inspection system, hydraulic pump are carried to driving end
For power, driving end fastens high-strength bolt, including angular transducer, pressure sensor, host computer, PLC controller and
Servo motor, type are input to host computer, send PLC controller to host computer output corresponding pressure value, PLC is converted to pressure value
Servo motor drives electric signal output, servo motor driving hydraulic pump works, hydraulic pump outlet pressure sensor acquisition pressure letter
Number feed back to PLC, PLC output adjustments signal to servo motor automatically adjusts the pressure of hydraulic pump；It is installed on driving end angled
Sensor, the real-time recording angular of angular transducer send PLC.
The PLC exports real-time pressure value and cumulative angle value to host computer.
The beneficial effects of the utility model are：The utility model hydraulic spanner operation automatic inspection system, it is automatic to monitor
Pressure during hydraulic spanner fastening bolt, process are preserved with result data, and abnormity early warning ensures that each operation high quality is completed, and tires out
Carry out longevity assessment is counted, prevents potential risk in advance.System can realize the very qualified of hydraulic spanner operation.
Description of the drawings
Fig. 1 is the utility model hydraulic spanner operation automatic inspection system structural schematic block diagram.
Specific embodiment
The utility model hydraulic spanner operation automatic inspection system structural schematic block diagram as shown in Figure 1, host computer is interior to be configured
There is technical recipe table, moment values required when bolt fastens, and more driving end are provided by technical recipe table according to wind turbine type
Verification report formula torque value be converted into pressure value send PLC controller, pressure value is converted to servo motor driving electricity by PLC
Signal is sent out, servo motor driving hydraulic pump works, and hydraulic pump outlet increases pressure sensor, pressure sensor acquisition pressure letter
Number feed back to PLC, the moment values corresponding pressure value of PLC and output is compared, and adjustment output is to servo motor, automatic adjustment
The pressure of hydraulic pump ensures that hydraulic pump to pressure value needed for driving end, forms and is closed control；Angle biography is increased on driving end
Sensor, by angular transducer come real-time recording angular, the signal of angular transducer acquisition send PLC, PLC by recording angular and
Calculation rate and corresponding pressure value automatic decision bolt are tightened.
In order to ensure precision：It is compared by increasing pressure sensor to acquire pressure value and setting pressure value, servo motor
The control pressure of close ring is realized, to ensure pressure value；Pressure auto-control using high-precision pressure sensor, avoids
Vision adjusts mechanical indicator error；System corresponds to spanner verification report according to type, gives the formula of torque value, and with configuration
The value that good technical recipe table provides is corrected by comparison, to ensure the accuracy of torque；If pressure adjustment terminates, working
Abnormal conditions change in the process, should and alarm, to ensure that the unstable personnel of output pressure do not know the situation of situation.
Realize fool-proof design：Technical recipe is configured before use, can be completed certainly by servo motor and pressure feedback
Dynamic pressure regulation；When bolt fastens, judge whether bolt twists by the angle variable rate on driving end and pressure value size
Tightly；The angle value of bolt is automatically extracted by equipment and is associated with technological requirement；Complete life cycle management is designed, and is reminded more
Tool is changed according to the quantity used to wear spare part.
In addition to angle value in use to bolt in using records in system, also hydraulic spanner is carried out in itself complete
Life cycle is managed.Spanner and pump have sealing ring and critical component to have theoretical life, are once remembered according to every work
It is primary to record all parts work, needs replacing when reaching the progress early warning prompting of theoretical value 90%, when reaching 100%, then alarms
Software normal work can not be started, the current number of 0 value is assigned again after replacing component, reach preventive maintenance in this way, avoid closing
Key member catastrophic failure causes tool risk safe to use.
In order to ensure the safe handling of system, system imports system configuration into fashionable setting user's modification logging
There is licencing key with parameter adjustment modification, anti-locking system answers human factor to cause work abnormal.
Type Process configuration is set in advance in host computer, and personnel on site avoids scene and calculates pressure, effectively prevent people
Member's pressure regulation mistake.Automation is realized in pressure regulation, and according to the pressure data in technical recipe, automatic Regulation base measuring pressure value is realized certainly
Dynamic pressure regulation avoids the pressure regulation of personnel's vision and generates larger error.Bolt tightens automatic judgement bolt and tightens completion, passes through spanner
The angular transducer feedback angle political reform rate of head judges whether bolt is tightened automatically, avoids and visually sees sleeve rotation to judge
Whether bolt is tightened.
Host computer has preset technical recipe, and sets the alarm of bolt data error range according to technological requirement, works as generation
When bolt owes torque or super torque, system automatic alarm, and warning message is recorded automatically.Host computer can each station work
Automatically go out all bolt data information reports beaten of the station after work, and after every work, it is each to provide this
Station executive condition report, avoid needs manually recorded information back every time, improves work efficiency.Host computer has hydraulic pressure to pull
Hand lifecycle management system, whenever work is primary, all parts record service life is primary, when part life reaches the predetermined longevity
Life 90% when early warning, prompting will replace parts, reach advancing preventive repair.
