The defect of traditional indisputable cobalt area operation has been overcome to this frock, can be convenient fixedly paste indisputable cobalt area, the reduction process time when reaching good coupling, improve detection efficiency, reduce the time of measurement personnel operation in the stove, avoid the potential safety hazard.
Description
Technical field
This utility model relates to the auxiliary mould of a kind of Guided waves that stretches for boiler tube bundle magnetic hysteresis.
Background technology
Guided wave is a kind of spread state mechanical elasticity ripple by communication media geometric constraints, the ultrasound wave such as propagated in pipeline, rod member and flat board etc. or sound wave, the magnetostrictive effect utilizing ferrum cobalt band or steel pipeline self produces ultrasound wave, it is achieved the detection of defect of pipeline.Restraining boiler economizer, the vaporizer of solid matter when carrying out magnetic striction wave guide detection, generally use ferrum cobalt band to be pasted on pipe surface, this stickup fixed work order expends the time very much, inefficiency.Also having employing rubber strip canoe to fix ferrum cobalt band, which reaches to detect coupling ratio and relatively expends the time, and easily causes the dislocation of ferrum cobalt band when being wound around rubber strip, affects signal transmitting and receiving effect.General boiler tube bundle Site Detection is it is generally required to the data acquisition of tens of point, and furnace inner space is limited, sultry, stuffy, it is not suitable for long working, the most traditional ferrum cobalt band is pasted, fixed form exists certain defect, its operation is inconvenient, time-consuming, efficiency is low, and there is certain potential safety hazard.
It is highly desirable to design and produce a kind of special frock, it is possible to the most fixing stickup ferrum cobalt band, activity time can also be reduced while reaching good coupling, improve detection work efficiency, reduce testing staff's time of operation in stove.
Summary of the invention
Technical problem to be solved in the utility model is to provide the auxiliary mould of a kind of Guided waves that stretches for boiler tube bundle magnetic hysteresis, this frock overcomes the defect of conventional iron cobalt band operation, stickup ferrum cobalt band can be fixed easily, activity time is reduced while reaching good coupling, improve detection efficiency, reduce testing staff's time of operation in stove, it is to avoid potential safety hazard.
For solving above-mentioned technical problem, this utility model includes rectangular frame for the stretch auxiliary mould of Guided waves of boiler tube bundle magnetic hysteresis, rotating shaft, restraint zone, ratchet, check pawl, rocking bar, link and hands handle, described rotating shaft level penetrates described rectangular frame, described ratchet is located at described rotating shaft two ends and is positioned at described rectangular frame both sides, described check pawl is located at described rectangular frame both sides and against described ratchet surface, described restraint zone is wound in described rotating shaft, described rocking bar is located at described rotating shaft one end, described handle is located at described rectangular frame bottom surface by described link.
Further, this frock also includes that rubber blanket, described rubber blanket surface are provided with arcwall face and are located at the end face of described rectangular frame.
Further, this frock also includes clamp clip, and described clamp clip is fixing with the free end of restraint zone to be connected, and rectangular frame is arranged over fixing groove in described rotating shaft, and after described clamp clip is together with restraint zone winding tube bank, described clamp clip is placed in described fixing groove.
Owing to this utility model have employed technique scheme for the stretch auxiliary mould of Guided waves of boiler tube bundle magnetic hysteresis, the i.e. rotating shaft level of this frock penetrates rectangular frame, ratchet is located at rotating shaft two ends and is positioned at rectangular frame both sides, check pawl is located at rectangular frame both sides and against ratchet surface, restraint zone is wound in rotating shaft, rocking bar is located at rotating shaft one end, and handle is located at rectangular frame bottom surface by link.This frock overcomes the defect of conventional iron cobalt band operation, it is possible to the most fixing stickup ferrum cobalt band, reduces activity time, improves detection efficiency, reduce testing staff's time of operation in stove, it is to avoid potential safety hazard while reaching good coupling.
Accompanying drawing explanation
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is that this utility model stretches for boiler tube bundle magnetic hysteresis the auxiliary mould schematic diagram of Guided waves.
Detailed description of the invention
Embodiment is as shown in Figure 1, this utility model includes rectangular frame 1 for the stretch auxiliary mould of Guided waves of boiler tube bundle magnetic hysteresis, rotating shaft 2, restraint zone 3, ratchet 4, check pawl 5, rocking bar 6, link 7 and handle 8, described rotating shaft 2 level penetrates described rectangular frame 1, described ratchet 5 is located at described rotating shaft 2 two ends and is positioned at described rectangular frame 1 both sides, described check pawl 5 is located at described rectangular frame 1 both sides and against described ratchet 4 surface, described restraint zone 3 is wound in described rotating shaft 2, described rocking bar 6 is located at described rotating shaft 2 one end, described handle 8 is located at described rectangular frame 1 bottom surface by described link 7.
Preferably, this frock also includes that rubber blanket 9, described rubber blanket 9 surface are provided with arcwall face and are located at the end face of described rectangular frame 1.The rubber blanket surface arc face curvature is suitable with the curvature of detected tube bank, and when this frock rotates around detected tube bank, rubber blanket can fit tightly with detected tube bank surface, thus improve ferrum cobalt band and paste the quality being fixed on detected tube bank surface.
Preferably, this frock also includes clamp clip 10, and described clamp clip 10 is fixing with the free end of described restraint zone 3 to be connected, described rectangular frame 1 is arranged over fixing groove 11 in described rotating shaft 2, described clamp clip 10 and fixing slot fit, can fix the position of restraint zone, it is simple to tightening up of restraint zone.
When boiler tube bundle magnetic hysteresis stretches Guided waves, by being cropped to inside the ferrum cobalt band of Len req one side uniform application coupling glue, by the one side of ferrum cobalt band spreading glue near tube surface, press...with one's finger foundary weight cobalt band make two ends parallel alignment;One holds handle by rectangular frame end face against tube surface, according to the restraint zone of caliber size pull-out certain length, together with restraint zone, restraint zone or clamp clip is walked around pipe and ferrum cobalt band one week so that ferrum cobalt tape wrapping is in tube surface;Now, shake rocking handle makes restraint zone tighten up, or is positioned over by clamp clip in fixing groove, and shake rocking handle makes axis of rotation, shrinks restraint zone, until clamp clip and fixing groove cannot relative movement again so that ferrum cobalt band fits tightly with tube surface;Check pawl pins ratchet and keeps the regular hour simultaneously;After glue to be coupled solidifies completely, unclamping check pawl, loosen restraint zone and take out this frock, now ferrum cobalt band can fit tightly with tube surface, improves magnetic hysteresis and stretches the precision of Guided waves.
This frock uses manual rocking handle to shrink control restraint zone, ferrum cobalt band is made to fit tightly with tube bank surface, reach the effect of good coupling, boiler tube bundle magnetic hysteresis can be rapidly completed stretch the fixing stickup of ferrum cobalt band in Guided waves simultaneously, fixing adhering processes time-consumingly can be greatly reduced, and is effectively improved detection efficiency;This frock is easy to use, replaces the repeatedly winding of original employing rubber strip, and can be repeatedly used for a long, and saves production cost and beneficially environmental protection.
