Background technology
In industries such as electric power, chemical industry, weaving, existing a large amount of is the heat exchanger of carrier with water.These heat interchanger are made up of a large amount of pipelines, and its internal pipeline is many and gather, and its spacing is narrow, and the checkout equipment size is restricted.Pipe ultrasonic ripple testing process require sensor well with detect tube contacts, holding signal is stable, require to pass pipeline center when wearing, the detection system miniaturization, people's operating instrument is held ultrasonic sensor, design that necessary anchor clamps become must.For at narrow space easily to wearing the use ultrasonic sensor, the sensor of Selection of Sensor side direction lead-in wire avoid afterbody to take up room, so the spy designs gripper for this reason.
The utility model content
The purpose of the utility model provides a kind of anchor clamps that are used for the pipe ultrasonic ripple to the wear measurement probe, when reducing the anchor clamps width to greatest extent, can realize the accurate centering of probe.
A kind of anchor clamps that are used for the pipe ultrasonic ripple to the wear measurement probe of the utility model; Comprise: nesting frame assembly, the tailgate that is positioned at nesting frame assembly both sides and probe fixture; Said nesting frame assembly is arranged with 4 layers of grip block in parallel; Correspondence position is provided with the semicircle opening identical with the pipe under test diameter on the said grip block, and semicircle opening two-end-point place is provided with the probe fixture respectively between said second, third grip block.
Axially offer shoulder hole in the said probe fixture.
Offer front end lead-in wire groove on the said probe fixture.
Said probe fixture tail end, second, third grip block correspondence position also offer the pressure strip slot.
Said nesting frame assembly is two nested integral body that are connected in rectangular parallelepiped bottom surface.
The wall thickness of said nesting frame assembly is 1mm.
The said pipe ultrasonic ripple that is used for also comprises several fonts probe pressure strips to the anchor clamps of wear measurement probe, and said pressure strip is arranged in the pressure strip slot, and two ears of pressure strip link to each other through spring, nut with tailgate respectively.
The utility model is a kind of to be used for the pipe ultrasonic ripple and to the advantage of the anchor clamps of wear measurement probe to be: the center of circle of probe fixture center and pipe under test is positioned at same horizontal line; Thereby make the sound wave of two probes just in time pass pipeline center; Probe just is fixed in the probe fixture, and the probe fixture guarantees that the repetitive positioning accuracy of probe is 0.5mm, solved because of centering inaccurate with should operating instrument again static probe give and survey trouble caused; Anchor clamps are to the location of probe; Guaranteed the symmetry that transmitting probe and receiving transducer are settled, in having avoided detecting because of the dynamics of pushing of the symmetry of two probes, probe, probe push artificial factor such as angle, significantly reduced detection difficulty and detection cost; Be the much progress that pipe ultrasonic detects, guaranteed the safe operation of pipeline; Offer the lead-in wire groove at probe fixture front end, the lead of probe tail end is passed from the front portion, reduce the anchor clamps integral width, help using in the place that intensive pipeline distributes.

Wherein, 1,2,3,4 is grip block, and 5,6 is tailgate, and 7 are the probe fixture, and 8 is semicircle opening, and 9 are front end lead-in wire groove, and 10 is the pressure strip slot, and 11 is a few font probe pressure strips, and 12 is spring, and 13 is shoulder hole.
Embodiment
Below in conjunction with accompanying drawing; The utility model is further specified: shown in Fig. 1-4; A kind of anchor clamps that are used for the pipe ultrasonic ripple to the wear measurement probe; Comprise: nesting frame assembly, the tailgate 5,6 that is positioned at nesting frame assembly both sides and probe fixture 7, said nesting frame assembly is arranged with 4 layers of grip block 1,2,3,4 in parallel, and correspondence position is provided with the semicircle opening 8 identical with the pipe under test diameter on the said grip block 1,2,3,4; Said second, third grip block 2, semicircle opening 8 two-end-point places are provided with probe fixture 7 respectively between 3, the coincidence of the axis of said probe fixture 7 and the center of circle of pipe under test.
Said nesting frame assembly bends to two rectangular parallelepipeds of size for adopting the thick stainless steel of 1mm, and inside and outside double-layer structure adopts the resistance spot welding method to be integrally formed, and forms four layers of grip block 1,2,3,4.
Said probe fixture 7 is rectangular parallelepipeds of 20mm * 20mm * 35mm, sees Fig. 4, and axially shoulder hole 13 is opened in the centre, and shoulder hole 13 diameters are respectively 15mm and 16mm, and the length of aperture 15mm section is 5mm, and probe diameter also is 15mm, and probe is therein for movingly; The length of aperture 16mm section is 30mm, and the portion of popping one's head within it is around axially swinging; Probe fixture 7 one sides are opened the front end lead-in wire groove 9 of wide 10mm, dark 20mm, and the newel post of being convenient to go between when ultrasonic probe is installed can conveniently draw from the probe front end, and two probes are arranged along the pipeline radial centre lines relatively.Ultrasonic probe can move forward and backward in the fixture 7 at probe, because the opening size of anchor clamps is consistent with line size, has only anchor clamps are stuck in fully and could realize the centering of popping one's head on the pipeline.
Said probe fixture 7 tail ends, second, third grip block 2,3 correspondence positions also offer pressure strip slot 10.
The said pipe ultrasonic ripple that is used for also comprises several fonts probe pressure strips 11 to the anchor clamps of wear measurement probe, and said pressure strip 11 is arranged in the pressure strip slot 10, and two ears of pressure strip 11 link to each other through spring 12, nut with tailgate respectively.Probe is closely related with pipeline coupling situation and stress relation, therefore requires to apply certain power at probe.For the pipeline of certain diameter, the changes in spacing of two probes is very little, and is easy for installation for ease of popping one's head in, and design permission variation range is 3mm.Adopt spring to exert pressure probe is closely contacted with pipeline outer wall, because the acting force that the spring of hold-down mechanism applies is directly proportional with decrement, for guaranteeing to act on when the caliber variation to be detected the power substantially constant of probe; Compression spring is a certain amount of in advance when fixing tailgate; Movement pressure does not act on the probe fixture when having probe, probe back movement pressure is installed is acted on the probe, therefore changes when little at caliber; Amount of spring compression changes little, and acting force is also just constant basically.Adopt four springs altogether, each a few font probe pressure strip is with two springs.
