Description

High-tension porcelain insulator flaw detection creeping wave probe clamper
Technical field
The present invention relates to a kind of probe clamper, particularly one and be applicable to 110kV to 220kV high-voltage strut porcelain vase UT (Ultrasonic Testing) creeping wave probe dedicated workholder.
Background technology
High-voltage strut porcelain vase is as the vitals forming isolation switch, and its operation conditions is directly connected to the security of operation of electrical network.Due to high-voltage strut porcelain vase manufacturing process and the stressed impact of long period of operation, once there is a lot of electric network fault caused because support insulator occurs in operation to rupture in recent years.In order to the high-voltage strut porcelain vase of Timeliness coverage existing defects, prevent its fracture that meets accident in operation, electric system has been carried out and has been carried out UT (Ultrasonic Testing) detection to operating high-voltage strut porcelain vase, and emphasis adopts the surface crack of climbing ripple detection method detection high-voltage strut porcelain vase mucilage binding position and hiding.
When carrying out high-voltage strut porcelain vase carrying out flaw detection, testing staff adopts a hand-held defectoscope usually, and another hand pinches creeping wave probe and detects in the method for the surface movement of high-voltage strut porcelain vase.Owing to detecting the restriction of position and site work condition, often occur because creeping wave probe is not in place from porcelain vase surface contact, testing staff presses the phenomenon that dynamics is different, translational speed of popping one's head in is uneven and detection that is that cause is lack of standardization, inaccurate, not in place in operation, had a strong impact on accuracy and the detection efficiency of high-voltage strut porcelain vase detection.
In order to solve Problems existing in porcelain vase carrying out flaw detection, instrument manufacturer facility man in succession take improve creeping wave probe profile, arrange that probe is outer grabs the methods such as handle, but owing to still adopting mode that is manually hand-held and pressing probe to detect, onsite application effect is unsatisfactory.Porcelain vase carrying out flaw detection phenomenon lack of standardization, inaccurate, not in place still exists.
Summary of the invention
The object of the invention is to solve the deficiencies in the prior art part, and a kind of high-tension porcelain insulator simple to operate, easy to use flaw detection creeping wave probe clamper is provided.
A kind of high-tension porcelain insulator flaw detection creeping wave probe clamper, its structural feature is: include one with movable part and fixed part can the rotation porcelain vase folder of folding, movable part and fixed part surround a ring texture when closing, a compression for static probe is cranked arm, mode for realizing plane relative motion between described movable part and fixed part is hinged, fixed part is provided with handle, the mode of gimbal suspension formula is adopted to be connected between handle with fixed part, movable part is arranged the top board for opening and closing movable part, described top board is connected with the handle be arranged on handle by seizing wire, the spring for top board return is provided with between described top board and fixed part, handle the axis of opposite handle can move up and down thus drive seizing wire to move, and then drive movable part to do open and close movement, described compression is cranked arm and to be formed by two plates are hinged, compress two plates of cranking arm so that move toward one another can be done and heterodromous mode is hinged, compress the one end of cranking arm to crank arm with whole compression can relatively circumferentia do and be hinged on fixed part with heterodromous mode in opposite directions, crank arm and be provided with between fixed part can will compress the back-moving spring strained on fixed part of cranking arm in compression, the other end compressing curved wall is provided with creeping wave probe holder, upwards be arranged at intervals with rubber wheel walking along the annular of fixed part and movable part, the direction of the ring plain that the rotation direction of rubber wheel surrounds along fixed part and movable part is rotated.
The high-tension porcelain insulator flaw detection creeping wave probe clamper of this structure, in use, first being detected face place at high-voltage strut porcelain vase brushes one deck machine oil, creeping wave probe is pressed detection side in loading creeping wave probe holder, tighten both sides set bolt, connect good probe signal line between creeping wave probe and ultra-sonic defect detector.Hold the handle of clamper, clutch open handle make rotation porcelain vase press from both sides movable part open, rotation porcelain vase bracket is entered the below of tested high-voltage strut porcelain vase first porcelain patticoat, open handle and rotation porcelain vase clamp roll is taken turns and high-voltage strut porcelain vase close contact, clamp porcelain vase.Suitable adjustment compresses the height of cranking arm and makes creeping wave probe just be attached to high-voltage strut porcelain vase to be detected on face.Now, hold holder handle and mix up the turnover angle of handle according to standing place and left and right promotes to rotate porcelain vase folder, the creeping wave probe on clamper is slided around high-voltage strut porcelain vase, the flaw detection of high-voltage strut porcelain vase can be carried out and climb ripple and have detected.
Work complete, clutch handle and rotation porcelain vase folder movable part is opened, clamper can take off from high-voltage strut porcelain vase by light handle.
Described handle is connected with the gimbal suspension formula between fixed part, the connecting plate of one section is connected with between fixed part and handle, be provided with the ring surface direction sports limiting hinge along fixed part and movable part between connecting plate and fixed part, be provided with between connecting plate and handle and handle can be made to turn up relative to ring surface or the folding hinge of opening movement.
The gimbal suspension formula of this structure connects, and can ensure that handle realizes left and right, swings up and down in required angle, can easily pack up again folding, convenient collection.
In sum, the present invention has the following advantages compared to existing technology:
High-tension porcelain insulator flaw detection creeping wave probe clamper of the present invention, creeping wave probe is fixed on stable rotation porcelain vase folder, the whole slide rotating porcelain vase folder is utilized to realize the movement of popping one's head in, its scope detected is larger, probe is mobile more smooth-going, speed evenly, avoid over to pinch when probe detects with hand and easily occur detecting the problem at dead angle.Secondly compress owing to have employed the pressure providing and be applied on probe of cranking arm, make to fit between probe and porcelain vase tightr, stressed evenly, farthest decrease because different testing staff presses the metrical error that dynamics difference brings.3rd have employed folding holder handle, when allowing testing staff detect on the framework of high-altitude, can detect without the need to repeatedly squatting down and being shifted, be applicable to 110kV to 220kV high-voltage strut porcelain vase UT (Ultrasonic Testing) and climb ripple detection use, namely ensure that safety when testing staff detects in high-altitude, alleviate labour intensity again, also substantially increase the efficiency of Site Detection simultaneously.
