Description
Technical field
The utility model relates to metal material nondestructive testing technique field, belongs to a kind of overflow type steel pipe ultrasonic probe, is applicable to that the steel pipe spiral advances, the Non-Destructive Testing of the steel pipe of diameter 〉=Φ 76mm.
Background technology
In order to guarantee the product quality of steel pipe, carry out Non-Destructive Testing to steel pipe, with in the method for ultrasonic inspection, the diameter of steel pipe 〉=Φ 100mm generally adopts the steel pipe spiral relatively-stationary form of advancing, pop one's head in.In the process of ultrasonic inspection, need to use couplant between probe and the measured object, in automatic flaw detection of steel pipes generally all water make couplant.According to the ultrasonic inspection principle, the axis of probe is wanted the certain distance of parallel offset diameter of steel tube direction, i.e. eccentric throw; The outside surface of probe and steel pipe will keep the distance of about 20mm simultaneously, and this distance must be stable, and these are called the tracking of probe to outer wall of steel pipe technically.In order to keep the stable of water layer, pop one's head in below steel pipe.Therefore just must have a cover mechanical hook-up to guarantee these requirements, equipment in the past all adopts the form of guide pin bushing or spring device to follow the tracks of, and probe is immersed in the tank in order to guarantee water layer.Because the qualified steel pipe of physical dimension exists straight degree, the roundness deviation of permission, all there are some problems in these devices on following the tracks of and adjusting, warp must be outer through several millimeters greater than steel pipe in the guide pin bushing, otherwise steel pipe just can not penetrate guide pin bushing, tracking effect is undesirable like this, the specification quantity of the quantity of guide pin bushing and quilt spy outer diameter of steel pipes has direct relation simultaneously, is difficult for adjusting operation, and the device fabrication cost is big; Spring device vibration is big, and it is fragile to pop one's head in, and it is big that these mechanisms all deposit mechanical vibration, the problem that noise is high.In order to detect reliably, prevent the mistake spy, must block up the steel pipe two ends with end socket, avoid a large amount of water inlet the in the pipe, so just increased operating personnel.
Summary of the invention
The purpose of this utility model provides a kind of overflow type steel pipe ultrasonic probe, and it can make probe reliably tested outer wall of steel pipe be followed the tracks of, and tracking effect is good, adjustment, easy to operate when replacing is detected the steel pipe specification, do not need guide pin bushing and end socket, mechanical vibration are little, and noise is low.
For achieving the above object, adopted following design proposal;
A kind of overflow type steel pipe ultrasonic probe is characterized in that: it includes hyperchannel probe, opening water jacket, and this probe is arranged in the opening water jacket, is connected with delivery hose at the rear portion of water jacket.
Described water jacket bottom is provided with support, be provided with two bearings at the top of this support, in these two bearings, be provided with a hinged axis of swing, radially be fixedly connected with acclivitous supporting plate respectively in both sides at this hinged axis of swing middle part, be respectively arranged with dovetail groove and regulate supporting plate and slide plate on the supporting plate of these both sides, slide plate is provided with the support plate that is connected with water jacket.
Both sides at water jacket are provided with tracking wheel, are connected with pole in the bottom of tracking wheel, and cross connection has the wheel distance regulating rod under two tracking wheels of water jacket one side.
Described pole lower end is connected with transverse slat, is connected with the spring that joins with support in this transverse slat lower end.
The described distance regulating rod of taking turns is provided with adjustment hole, inserts pin in the adjustment hole of the two wheel distance regulating rods that intersect.
The utility model has the advantages that: probe is good to the tracking effect of outer wall of steel pipe during flaw detection, and adjustment, easy to operate does not need guide pin bushing, end socket when replacing is detected the steel pipe specification.

Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5:
A kind of overflow type steel pipe ultrasonic probe, it includes hyperchannel probe 18, opening water jacket 3, and this probe 18 is arranged in the opening water jacket 3, is connected with delivery hose 19 at the rear portion of water jacket.
Described water jacket bottom is provided with support 11, be provided with two bearings 12 at the top of this support, in these two bearings, be provided with a hinged axis of swing 10, radially be fixedly connected with acclivitous supporting plate 9 respectively in both sides at this hinged axis of swing middle part, be respectively arranged with dovetail groove and regulate supporting plate 7 and slide plate 8 on the supporting plate 9 of these both sides, slide plate 8 is provided with the support plate 16 that is connected with water jacket.
Be provided with tracking wheel 2 in the both sides of water jacket, be connected with pole 15 in the bottom of tracking wheel 2, cross connection has wheel distance regulating rod 4 under two tracking wheels of water jacket one side.
Described pole 15 lower ends are connected with transverse slat 14, are connected with the spring 13 that joins with support in these transverse slat 14 lower ends.
The described distance regulating rod 4 of taking turns is provided with adjustment hole, inserts pin 17 in the adjustment hole of the two wheel distance regulating rods that intersect.For the tested steel pipe of different-diameter, with the position that pin 17 inserts different adjustment holes 5, the distance that is used for regulating steel pipe radial tracking wheel is to adapt to the steel pipe of different-diameter.
During use, detected steel pipe 1 self rotation and rectilinear motion under being driven by running roller on the roller-way are that spiral advances.Tracking wheel 2 is close to tested steel pipe 1 wall that spiral advances, and makes the probe 18 and the distance of steel pipe 1 outer wall keep stable, reaches good tracking effect.
Because the water jacket physical dimension in the overflow type probe is much smaller with respect to existing tank, steel pipe 1 is when advancing, steel tube head during near water jacket the distance apart from probe very little, steel tube head can pass through water jacket 3 soon, in the flaw detection process, steel tube head does not need stifled upper cover, has saved manpower and materials.
National standard requires the blind area of can not visiting of steel tube end part to be≤200mm to the method for automatic flaw detection of steel pipes.The speed of steel tube ultrasonic inspection is generally 6-30m/min, i.e. 100-500mm/s, the about 100mm of the length of this probe water jacket 3, the time of water jacket 3 was passed through less than 1 second in the end, intake seldom in the pipe, coverage therefore need be at the stifled upper cover of steel tube end part in the blind area.
