Description
Technical field
The utility model relates to a kind of heat exchanging pipe scanning detection probe, finned heat exchanging pipe scanning detection probe belongs to the robot application field in particularly a kind of small space.
Background technology
Bearing pipe is the critical component in the heat power plant boiler heat exchanger, being multilayer on its distribution solid arranges, the degree of depth reaches 1.5 meters, being the U type in the plane distributes back and forth, pipe surface has the screw type heat-exchanging fin, fin and fin pitch 12.5mm, the dark 3.5mm of fin, horizontal adjacent channel minimum spacing 48.5mm, two-layer up and down pipeline enclosure minor increment 28mm.The pipe shape of this complexity, spatial disposition and narrow and small spacing between pipes detect for the inner layer pipe external defects and have brought certain difficulty.In the present circumstance, the detection of this bearing pipe is only limited to its top layer pipeline external surface be detected by artificial visually examine's mode in the boiler maintenance period, then powerless to its lower floor's pipeline external surface defects detection.Therefore, the utmost point is necessary to develop a kind of robot device that can scan and detect the external defects of all pipelines in this type of bearing pipe group, realize detection to all pipeline external surface defectives, robot with its size of detection probe must be as far as possible little, must be able to arrive the optional position in the plane, pipeline top layer, and this scanning detection probe is furnished with suitable light source, the brightness of light source can be adjusted, so that the CCD image sensor clearly is reproduced in the tested pipeline surface state on the monitor screen.Thereby judge that for correct the pipe surface defective provides the basis.Find through the Searches of Patent Literature, China Patent No. is: ZL01278852.X, application is artificial: Unis, name is called " flat ccd scanner headstock light channel structure ", this patent disclosure a kind of flat ccd scanner headstock light channel structure, it comprises light source, the CCD photoelectric sensor that is installed on the ccd scanner headstock plate, and the reflected light path that constitutes of four catoptrons and lens.It is 270mm to the total optical path of photoelectric sensor that the light channel structure of this utility model satisfies from being scanned image, has simple and practically, and cost is lower, and thickness is less, and the image scanning quality is than advantages such as height.This patent disclosure be a kind of probe light channel structure that is used for flat ccd scanner, probe is shaped as strip, size is big, can not scan detection to finned heat exchanging pipe in small space, relates on structure and purposes all inequality with the utility model.
Summary of the invention
The purpose of this utility model is at deficiency of the prior art, finned heat exchanging pipe scanning detection probe in a kind of small space is provided, make itself and detection machine people supporting, can arrive the optional position in the plane, pipeline top layer, finned heat exchanging pipe be scanned detection thereby finish in small space.The utility model is realized according to following technical scheme, mainly comprise: probing shell, last blind nut, CCD image sensor, lower spiro cover, electroluminescent lamp, lamp bracket, its connected mode is: go up blind nut and probing shell and tighten, 4 electroluminescent lamps insert in the inclined hole of lamp bracket, after lead company, insert lower spiro cover together, lower spiro cover and probing shell are tightened, and the CCD image sensor is arranged in probing shell and the lower spiro cover assembly.
The head conical surface of CCD image sensor is pressed in the center taper hole of lamp bracket, and the scanner head of CCD image sensor is pressed in the center taper hole of lower spiro cover, and last blind nut and probing shell are tightened, and compresses the tail end of CCD image sensor.
In the light source loop of electroluminescent lamp, be connected in series a variable resistor, detect in the debug process in scanning, the adjusting variable resistor can change the voltage on the electroluminescent lamp, thereby changes brightness, and the image that the CCD image sensor is obtained is the clearest.
With finned heat exchanging pipe scanning detection apparatus in the supporting small space of detection machine people, by the deceleration direct current generator, sliding shaft sleeve, two support plates, suspension rod, mechanical arm, dividing plate, rotating shaft, two photoelectric sensors, code-disc and the utility model are formed, be installed on detection machine people's the mechanical arm, detection machine people extend into probe among the fin pipeline group, when arriving the center of 4 adjacent channels of appointment, the axis of terminal reducing motor stops, at this moment, deceleration direct current generator energising running, rotate a certain angle from sagging position through rotating shaft driven sweep detection probe, make probe over against the pipeline that is scanned detection, angle is controlled by code-disc and photoelectric sensor, then, robot begins to move along the pipeline axial direction, simultaneously, CCD image sensor and light source also begin scanning work, and constantly pipe surface state image is passed to the upper monitoring machine, when scanning this pipeline end, robot stops to move, deceleration direct current generator energising running, rotate a certain angle from current position through rotating shaft driven sweep detection probe, make probe need scan the pipeline of detection over against another, angle is controlled by code-disc and photoelectric sensor, then, robot begins again to return mobile along the pipeline axial direction, simultaneously, CCD image sensor and light source also begin scanning work, and constantly this pipe surface state image are passed to the upper monitoring machine.Such scanning is after multiple 4 times, and the scanning that just can finish these specified 4 adjacent channels detects task, and then, the running of switching on again of deceleration direct current generator rotates to sagging position through rotating shaft driven sweep detection probe, and preparation is with stretching under the mechanical arm continuation.Then, robot controls when mechanical arm continues down to reach next center of organizing 4 adjacent channels again and stops, and from multiple above-mentioned work, finishes up to all pipeline scanning detections.
The utility model is finished the detection scanning of pipe surface on every side with the driving that CCD and combination of light sources are integral the reducing motor by the mechanical arm end, compact conformation, can arrive the optional position in the plane, pipeline top layer, the scanning that is fit to finned heat exchanging pipe surface in the small space detects, and it is a crucial ingredient of heat power plant boiler detection robot for bearing pipe of heat exchanger.
