Abstract
The utility model provides a magnetic leakage flaw detector vertical probe and actuating mechanism protection system sets up a proximity switch in probe actuating mechanism's bent axle rear end to add probe position detection control module in PLC, probe position detection control module is connected with proximity switch and converter respectively. When the proximity switch detection probe returns to the original position, the probe position detection control module sends a received signal to the frequency converter after processing the received signal, and controls the roller bed motor to operate for normal flaw detection; if the detection probe is not in the original position, the probe position detection control module controls the roller motor to stop rotating through the frequency converter, so that the problem that the probe is damaged by the steel pipe is effectively solved, the safety of the probe and an action mechanism is ensured, production stop accidents are avoided, the equipment operation rate and the unit yield are improved, spare part consumption is reduced, the production cost is reduced, and the labor intensity of operators is reduced.
Description
Technical field
The utility model belongs to automation field, relates in particular to a kind of protective device that is used for magnetic flux leakage testing device vertical sonde and actuating mechanism.
Background technology
The used magnetic flux leakage testing device of weldless steel tube carrying out flaw detection is that a kind of computerized leakage field is vertical, leakage field laterally reaches four probe ultrasonic thickness measurement combined type fault detection systems.Wherein most important parts is vertical leakage field unit, and vertically the leakage field unit mainly is made up of the magnetic pole of a cover rotation, 2 probes and actuating mechanism, adjustment unit, signal microprocessor and detecting element.Main pole is rotated with probe during work, and maximum number of revolutions is 350 commentaries on classics.
The vertical sonde actuating mechanism is made up of bidirectional electromagnetic valve, actuating mechanism and a probe; Probe is fixed on the front end of actuating mechanism; When solenoid-driven actuating mechanism, steel pipe got into vertical unit, mechanism stretched out by PLC (programmable logic controller) control action; Probe is attached on the tube wall, steel pipe through vertical unit after actuating mechanism return original position.Because dust and iron sheet are more on the rolling line; Therefore the steel pipe surfaces externally and internally all is stained with dust and graphite; Can be adsorbed onto in the turning joint of actuating mechanism owing to the action of a magnetic field when probe action mechanism gets into when vertical, make the copper sheathing of mechanism's rotation axis and bearing wear very fast, cause mechanism to stretch out or return not in place; When next root steel pipe is come, can knock probe, cause the damage of probe and actuating mechanism.Probe and actuating mechanism very expensive, and the order cycle time is long, has both influenced the direct motion of production, has increased production cost.
Summary of the invention
The utility model aims to provide and a kind ofly prevents the steel pipe probe of wounding, thereby enhances productivity, and reduces the magnetic flux leakage testing device vertical sonde and the actuating mechanism protection system of spare parts consumption.
For this reason, the solution taked of the utility model is:
A kind of magnetic flux leakage testing device vertical sonde and actuating mechanism protection system; Comprise PLC, frequency converter and electric machines for roller; It is characterized in that; The crankshaft rear end of probe action mechanism is provided with one near switch, in PLC, sets up probe positions and detects control module, and probe positions detects control module and is connected with frequency converter respectively with near switch.
Control method of the utility model and effect are:
When the steel pipe operation is come; What be located at crankshaft rear end is to return original position near switch as if detection probe; The probe positions of detection signal being sent in the PLC near switch detects control module, and probe positions detection control module will be exported signal after treatment and send to frequency converter, and the operation of Frequency Converter Control electric machines for roller is sent steel pipe into defectoscope; After the steel pipe head got into defectoscope, probe stretched out near pipe end and begins flaw detection; As not having not in position near the switch detection probe; Then probe positions detects control module through the stall immediately of Frequency Converter Control electric machines for roller, thereby prevents that effectively the probe that stretches out is not withdrawn when driving mechanism machinery or power network fluctuation tripping operation, misoperation; The problem that causes steel pipe that probe is broken; Not only guaranteed the safety of probe and actuating mechanism, avoided improving equipment operation rate and unit output because of the long stopping production accident that causes reset time; And can reduce spare parts consumption, and reduce production costs, alleviate operating personnel's labour intensity, improve the device security coefficient.
Description of drawings
Accompanying drawing is magnetic flux leakage testing device vertical sonde and actuating mechanism protection system structured flowchart.
Embodiment
Visible by accompanying drawing, magnetic flux leakage testing device vertical sonde and actuating mechanism protection system are mainly reached by PLC, frequency converter, electric machines for roller to be formed near switch.The utility model is on the basis of original PLC, frequency converter and electric machines for roller; The one, set up one near switch at the crankshaft rear end of probe action mechanism; The 2nd, in PLC, to set up a probe positions and detected control module, probe positions detects control module one end and is connected near switch, and the other end connects frequency converter; Frequency converter also is connected on the electric machines for roller simultaneously, and the start and stop of control electric machines for roller.
