Description
Technical field
The utility model relates to foreign material testing fixture in a kind of boiler header or pipeline, is particularly suitable for the inspection of boiler header and the inner foreign material of straight pipeline with holes.
Background technology
Along with the fast development of domestic fired power generating unit, the quantity of unit boiler header and pipeline constantly increases, with regard to 1000MW unit only header quantity just reach nearly 400, and in header, be furnished with many restricting orifices, what restricting orifice internal diameter was minimum only has 10mm, carries out strict cleannes inspection before requiring header to install and after installing.Check that difficulty and workload increase many virtually, according to traditional endoscopic apparatus inspection, need to consume a large amount of man power and materials, the demand of power plant construction progress and benefit cannot be met.
Utility model content
The purpose of this utility model is to provide foreign material testing fixture in a kind of structure boiler header simple, easy to use and with low cost or pipeline.
Foreign material testing fixture in a kind of boiler header or pipeline, its special feature is: comprise angular adjustment handle groove, this angular adjustment handle groove is provided with angular adjustment handle, thus make this angular adjustment handle groove slip relatively of angular adjustment handle capable of being, the bottom of this angular adjustment handle groove and one end of reflex reflector lens base hinged, this reflex reflector lens base is provided with reflex reflector lens, and the other end of this reflex reflector lens base and one end of light source base hinged, this light source base is provided with light source, the other end of this light source base and the bottom of aforementioned angular regulating handle hinged, thus by stretching, contracting angular adjustment handle changes the angle of reflex reflector lens base and light source base.
Wherein hinged all employings bearing pin is lived and is connected.
Wherein light source adopts flashlight, and this flashlight passes through rubber band colligation on light source base.
Wherein on angular adjustment handle groove, be provided with through hole, this through hole is detachably provided with set bolt, this set bolt is provided with fixed block, thus angular adjustment handle can be clamped on angular adjustment handle groove.
The utility model provides a kind of easy header and perforated tube internal check device, through probationary certificate, can meet the requirement of thermal power plant header and the inspection of perforated tube cleannes.Solve the cost issues adopting traditional endoscopic apparatus to check header and pipe cleanness red tape and costliness, application attestation at the scene can meet the demand of power plant construction progress and benefit.Testing fixture profile of the present utility model is light and handy, uses simple, easy to carry, can fill in, and can carry out the adjustment of angle of reflection in less pore in boiler header, for the cleannes inspection of job site, thermal power plant heating surface header and pipe interior.This instrument check header and pipeline convenient, directly perceived, examination scope is wide, can effectively find the grains of sand in pipeline, iron filings, oxidation scaling, oxidation scum, welding coating, the first-class particle foreign material of welding rod welding wire.

Detailed description of the invention
As Fig. 1, 2, 3, shown in 4, the utility model is foreign material testing fixture in a kind of boiler header or pipeline, comprise angular adjustment handle groove 2, this angular adjustment handle groove 2 is provided with angular adjustment handle 1, thus angular adjustment handle 1 can be slided by this angular adjustment handle groove 2 relatively, the bottom of this angular adjustment handle groove 2 and one end of reflex reflector lens base 5 hinged, this reflex reflector lens base 5 is provided with reflex reflector lens 4, and one end of the other end of this reflex reflector lens base 5 and light source base 6 is hinged, this light source base 6 is provided with light source, the other end of this light source base 6 and the bottom of aforementioned angular regulating handle 1 hinged, by stretching, contracting angular adjustment handle 1 changes the angle of reflex reflector lens base 5 and light source base 6.
Wherein above-mentioned all hinged all employings bearing pins 3 are lived and are connected.Light source can adopt flashlight 8, and this flashlight 8 passes through rubber band 7 colligation on light source base 6.On angular adjustment handle groove 2, be provided with through hole in addition, this through hole is detachably provided with set bolt, this set bolt is provided with fixed block, thus angular adjustment handle 1 can be clamped on angular adjustment handle groove 2.
Using method of the present utility model and operation principle are:
During use by drawing, hade degree regulating handle 1, make to reach minimum angles between reflex reflector lens base 5 and light source base 6, can fill in from the base hole header or pipeline easily, enter after in header and pipeline, again by drawing, stretching adjusting angle regulating handle 1, change the angle between reflex reflector lens 4 and light source and by the reflection characteristic of light, the situation in header passed to outside by reflex reflector lens 4, thus convenient observation.
