In the present embodiment, hoisting mechanism 5 is mainly by pedestal 53, be arranged on the rotating disk 52 on the pedestal 53, winding the dragrope on the rotating disk 52 51 and be installed in positioning supporting frame 1 respectively and suspension body 3 on be used to guide the pulley 54 of dragrope 51 to form, dragrope 51 is realized by wire rope, the one end is fixed on the rotating disk 52, the other end is connected with the center-pole 42 that can be positioned at suspension body 3 by the guide effect of the pulley 54 on positioning supporting frame 1 and the suspension body 3 successively, under the traction of dragrope 51, center-pole 42 can move up and down, thereby driving backstay 43 moves up and down, when backstay 43 moves upward the restriction of the below abutment ring 33 that is subjected to suspension body 3, under the pulling force traction that further makes progress, backstay 43 is drawn close to center-pole 42 gradually, and last whole radiographic source detent mechanism 4 is contained in the accommodation space 31 of suspension body 3.
Described film fixator 6 mainly is made up of deck 61 and the pallet 62 that is arranged on the deck 61, film is arranged on pallet 62 inboards, the surge pipe outer circumference surface at the medial surface of pallet 62 and place, weld seam place is complementary, thereby make film to be adjacent to, guarantee the sharpness of sensitivity of film imaging with face of weld.
Above-mentioned concrete structure and annexation thereof to each funtion part of the utility model testing fixture is illustrated, and will make a presentation its use below:
Can be found out that by above-mentioned introduction the utility model welding inspection device has contraction and launches two states, when being in contraction state, this testing fixture mainly is convenient to deposit and carry, and when also being convenient to install simultaneously it is incorporated in the voltage stabilizer flexibly.At this moment, suspension body 3 parallels setting with slide track seat 12, and as shown in Figure 2, radiographic source detent mechanism 4 is housed in the suspension body 3, and its elastic component 44 is in confined state.Whole device takes up room less, and is instant packed and carry.
When weld seam detects between needs are to lower seal head of voltage stabilizer and surge pipe, at first film is arranged on pallet 62 inboards of film fixator 6, film fixator 6 is fixed on the periphery of surge pipe weld seam 100, then the pedestal 53 of hoisting mechanism 5 is placed near the position of the handled easily voltage stabilizer, the radiographic source detent mechanism 4 that is in contraction state is inserted in the voltage stabilizer by manhole 81 together with the slide track seat 12 of positioning supporting frame 1, simultaneously, manhole supporting seat 11 is fixed on the manhole place by nut, thereby has finished the installation of testing fixture.
Just can carry out radiographic source input work after the installation, at first, the rocking handle of drive transmission device 2 overturns suspension body 3, turn to vertical position until suspension body 3, and this moment, the center line of suspension body 3 and the axial line of voltage stabilizer are on the same straight line, as shown in figures 1 and 3, handle hoisting mechanism 5 then and carry out unwrapping wire, at this moment, because action of gravity, under the traction of dragrope 51, whole radiographic source detent mechanism 4 slowly falls, simultaneously, the axial line of center-pole 42 and the axial line of voltage stabilizer also are on same the straight line all the time, and along with the whereabouts gradually of center-pole 42, each backstay 43 also stretches out from suspension body 3 gradually, elastic component 44 by compression rebounds gradually, when the disengaging from suspension body 3 fully of each backstay 43, elastic component 44 obtains discharging fully, recovers rapidly, thereby each backstay 43 struts fully, is umbrella.As shown in Figure 3, along with strutting of each backstay 43, its terminal roller 431 glides along the voltage stabilizer inwall, the whereabouts that further guarantees center-pole 42 is more stable, avoid center-pole 42 to depart from the voltage stabilizer axial line, thereby guarantee to treat that radiogenic positioning seat 41 can accurately enter in the center pit of dividing plate 20,, can carry out radiographic source transmission testing when the taper platform 412 of positioning seat 41 falls into the center pit of dividing plate 20 fully.
Because radiogenic positioning action is in the outside realization of voltage stabilizer, can insert voltage stabilizer inside accurately be very crucial problem to radiographic source so, the utility model adopts dual mode to guarantee that radiographic source can accurately locate, promptly at first adopting suspension body that radiographic source is adjusted to the corresponding to position of voltage stabilizer axial line discharges again, then in radiographic source decline process, by adopting gag lever post to make its more stable whereabouts, thereby guaranteed radiogenic reliable location, so that radiographic source can uniform irradiation to the weld seam of border, and then guaranteed the accuracy and the reliability of testing result.
The foregoing description only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this; can not limit protection domain of the present utility model with this; be not limited to the mode that feed screw nut cooperates as gear train; the gag lever post of suspension body is not limited to three; all equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the present utility model.
