Technical Field
The invention relates to the technical field of steel quality evaluation, in particular to an ultrasonic flaw detection device and application thereof.
Background
The ultrasonic flaw detection device is one of important instruments for evaluating the internal quality of steel, and the current method for manually detecting the flaw of the medium plate steel in a steel factory usually comprises the steps of sprinkling water on a steel plate and then detecting the flaw, but because the area of the steel is large, the water on the surface of the steel plate cannot meet the flaw detection requirement due to the flowing and volatilization of the water on the surface of the steel plate after sprinkling water, repeated sprinkling water is needed, the working efficiency is affected, and when the water on the surface of the steel plate does not meet the flaw detection requirement, the abrasion of a probe is increased, and the working quality of the probe is affected. Further, because the thickness of water is insufficient, a gap exists between the probe and the steel plate, and the probe is interfered to influence the flaw detection result. Accordingly, there is a need to provide an ultrasonic inspection apparatus that is stable, accurate and efficient to accommodate the requirements for quality assessment of steel.
In view of this, the present invention has been made.
Disclosure of Invention
The invention aims to provide an ultrasonic flaw detector and application thereof, which can control the movement of an ultrasonic probe according to the water level height of the steel surface, and avoid the conditions of damage of the ultrasonic probe and inaccurate flaw detection result.
Embodiments of the present invention are implemented as follows:
in a first aspect, the present invention provides an ultrasonic flaw detection apparatus, comprising a motion unit, a water spraying unit, a detection unit, and a control unit.
The motion unit comprises a base, a roller and a brake assembly, wherein the roller is arranged on the base, and part of the roller extends out of the base and is used for driving the ultrasonic flaw detection device to integrally move. The brake assembly comprises a wheel band-type brake and an electromagnetic coil, wherein the wheel band-type brake is arranged around the roller and is connected with the electromagnetic coil, so that the wheel band-type brake can be selectively contacted with the roller for braking the roller.
The water spraying unit comprises a water receiver and a nozzle, the water receiver is arranged on one side of the base, which is far away from the roller, the nozzle is communicated with the water receiver, and the water spraying port of the nozzle extends out of the surface of the base, so that water sprayed out of the nozzle can directly flow to the surface of steel, and the thickness of a water layer on the surface of the steel is ensured.
The detection unit comprises a fixing seat, an ultrasonic probe, a water immersion sensor and a first connecting piece, wherein the ultrasonic probe and the water immersion sensor are all installed on the fixing seat, the fixing seat is parallel to the base and arranged at intervals, one end of the first connecting piece is connected with the fixing seat, the opposite other end of the first connecting piece is connected with the base, the ultrasonic probe is arranged at intervals with a water spraying port of a nozzle, so that water sprayed by the nozzle can be directly sprayed near the ultrasonic probe, the height of a water layer during detection of the ultrasonic probe is ensured, the detection precision is ensured, the detection efficiency is improved, and the abrasion of the probe is reduced.
In order to further improve the detection precision and the detection efficiency of the ultrasonic flaw detection device, reduce the abrasion of a probe, the control unit is electrically connected with the water immersion sensor, the water storage device and the electromagnetic coil, so that the control unit can directly control whether the water storage device sprays water or not according to the thickness of a water layer detected by the water immersion sensor, thereby ensuring the thickness of the water layer on the surface of steel, improving the detection efficiency and ensuring the detection precision; meanwhile, whether the electromagnetic coil is electrified or not can be controlled, so that the braking of the roller is controlled, the detection precision is prevented from being reduced, and the probe is prevented from being worn.
The ultrasonic flaw detection device provided by the invention is applied to flaw detection of steel, and in the use process, the ultrasonic flaw detection device is directly placed on the surface of the steel, and the whole ultrasonic flaw detection device is driven to move on the surface of the steel through the movement of the roller so as to detect flaws of all parts of the steel.
Wherein, the water layer height that water logging sensor can detect steel surface, generally speaking, the water layer height that ultrasonic flaw detection required is more than or equal to 0.3mm. The control unit receives the detection result of the water immersion sensor and judges whether water needs to be sprayed by the water storage device or not and whether the electromagnetic coil of the brake assembly needs to be adjusted to supply electricity or not according to the detection result.
Specifically, when the water level of the steel surface detected by the water logging sensor is more than or equal to 0.3mm, the ultrasonic flaw detection device can work normally, and then the control unit controls the water storage device not to spray water at the moment, and the electromagnetic coil of the brake assembly is not powered, so that the ultrasonic probe can perform flaw detection normally.
When the water immersion sensor detects a water level of the steel surface of slightly < 0.3mm, for example, the following are satisfied: when the height of the water layer is less than or equal to 0.28mm and less than 0.3mm, the height of the water layer on the steel surface is slightly less than the height required by flaw detection, the water can be directly sprayed by the control unit to control the water storage device, and the water is sprayed out through the nozzle, so that the height of the water layer on the steel surface is increased, and the flaw detection requirement is met.
When the water level height of the steel surface is detected to be far smaller than 0.3mm by the water immersion sensor, for example, when the water level height of the steel surface is smaller than 0.28mm, the water layer thickness difference is larger, the water layer requirement for flaw detection cannot be met by short water spraying of the nozzle, therefore, the control unit controls the brake assembly to brake the roller, namely, the control unit controls the electromagnetic coil to be powered on, the wheel band-type brake to work and brake the roller, the ultrasonic flaw detection device stops flaw detection, the control unit controls the water storage device to spray water when controlling the brake assembly to brake the roller, water is sprayed out from the nozzle, so that the water level height of the steel surface is increased, when the water level height of the steel surface detected by the water immersion sensor is larger than or equal to 0.3mm, the ultrasonic flaw detection device meets the operation requirement, the control unit controls the electromagnetic coil not to be powered on, the wheel band-type brake does not work, the roller moves normally, and the ultrasonic flaw detection device continues to detect flaws on the steel surface, so that the probe damage and the problem of low detection precision caused by the lack of the water level height is avoided.
It should be noted that, because the temperature of the steel surface is higher, the evaporation of water is caused, and the area of the steel is larger, the water is dispersed, so that the water reservoir should need to continuously spray water, so as to ensure that the thickness of the water layer on the steel surface meets the requirements of flaw detection.
In an alternative embodiment, the end of the base close to the nozzle is provided with a second connecting piece, the second connecting piece extends along the side far away from the roller and is rotationally connected with the first connecting piece, and the purpose of the selective rotational connection of the second connecting piece and the first connecting piece is to facilitate replacement of the ultrasonic probe or the water sensor.

In this embodiment, the water spraying unit further includes a water pipe 123, and both ends of the water pipe 123 are connected to the water reservoir 121 and the nozzle 122, respectively.
The present embodiment provides an ultrasonic flaw detection device 100, which operates according to the following principle:
the ultrasonic flaw detection device 100 provided in this embodiment is directly placed on the surface of steel, and the movement of the roller 112 drives the whole ultrasonic flaw detection device 100 to move on the surface of steel, so as to perform flaw detection on each part of the steel.
The water level sensor 133 can detect the water level on the steel surface, and in this embodiment, the water level required for ultrasonic flaw detection is set to be not less than 0.3mm. The control unit receives the result of the detection of the water sensor 133 and determines whether water spraying by the water reservoir 121 is required and whether power supply to the electromagnetic coil 1132 of the brake assembly 113 is required to be adjusted according to the result.
Specifically, when the water level of the steel surface detected by the water logging sensor 133 is greater than or equal to 0.3mm, the ultrasonic flaw detection device 100 can work normally, and then the control unit controls the water reservoir 121 not to spray water and the electromagnetic coil 1132 of the brake assembly 113 not to be powered, and the ultrasonic probe 132 performs flaw detection normally.
When the water immersion sensor 133 detects a water level of the steel surface of slightly < 0.3mm, for example, it satisfies: when the height of the water layer is less than or equal to 28mm and less than 0.3mm, the height of the water layer on the steel surface is slightly less than the height required by flaw detection at the moment, the control unit can be directly used for controlling the water receiver 121 to spray water, the water is sprayed out through the nozzle 122, and the height of the water layer on the steel surface is increased so as to meet the flaw detection requirement.

It should be noted that, since the temperature of the steel surface is high, which causes evaporation of water, and the area of the steel is large, which causes dispersion of water, the water reservoir 121 should be continuously sprayed to ensure that the thickness of the water layer on the steel surface meets the flaw detection requirement.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
