Detailed Description
The invention is further described below with reference to the drawings and detailed description.
As shown in fig. 1, a positioning device includes a fixing flange 1, a moving flange 5, and a lifting flange 4 disposed between the fixing flange 1 and the moving flange 5, a cylinder 2 (in this embodiment, a secondary cylinder) disposed on the fixing flange 1, a control valve (not shown in the drawing) connected with the cylinder 2, a positioning pin 3 disposed on the cylinder 2, the positioning pin 3 being directly connected with a piston of the cylinder 2, and the positioning pin 3 being capable of positioning and releasing the fixing flange 1, the lifting flange 4, and the moving flange 5 along with expansion and contraction of the piston of the cylinder 2. The fixed flange 1, the hoisting flange 4 and the movable flange 5 are respectively provided with a plurality of positioning holes which are opposite to each other one by one and can allow the positioning pins 3 to pass through. The number of locating pins is 2 in the drawings and is only illustrative.
As shown in fig. 1, the cylinder 2 is provided with a first vent hole 6, a second vent hole 7, and a third vent hole 8, the control valve is connected with the first vent hole 6, the second vent hole 7, and the third vent hole 8 through a vent pipe, and controls the inflation and deflation of the vent holes, and the piston of the cylinder 2 stretches and contracts according to the inflation and deflation of the vent holes.
When the first vent hole 6 is inflated, the piston stretches out, and the positioning pin 3 penetrates into the positioning holes of the lifting flange 4 and the moving flange 5 to play a role in mutually positioning the fixed flange 1, the lifting flange 4 and the moving flange 5 (see figure 3);
when the first vent hole 6 is deflated and the third vent hole 8 is ventilated, the piston is contracted (first-stage contraction), the positioning pin 3 is retracted into the positioning hole of the lifting flange 4 from the positioning hole of the moving flange 5, at the moment, the fixed flange 1 and the lifting flange 4 are still mutually positioned and connected, and the moving flange 5 is separated from the lifting flange 4 (see figure 2);
when the first vent hole 6 is deflated and the second vent hole 7 is inflated, the piston is contracted (second-stage contracted), the positioning pin 3 is retracted into the positioning hole of the fixed flange 1, the hoisting flange 4 and the moving flange 5 are separated from each other, and complete disengagement of the three flanges can be realized (positioning is released, see fig. 1).
The control valve is far away from the strong radioactive area where the positioning device provided by the invention is positioned, is arranged in a relatively safe environment, and controls an external air source to perform air charging and discharging operation on the vent hole on the air cylinder 2 through the vent pipe, so that the effect of remote control is realized.
Finally, the specific application of the invention is illustrated.
In a strong-radioactivity hot chamber, a cylinder 2 is arranged on a fixed flange 1 which needs to be frequently positioned and contacted and positioned, a control valve is arranged in a safe environment outside the hot chamber and used for controlling an external air source, and ventilation holes on the cylinder 2 are inflated and deflated through a ventilation pipe. According to the inflation and deflation operations of different vent holes, the frequent positioning and release positioning operations among the fixed flange 1, the lifting flange 4 and the movable flange 5 are realized, and in the whole operation process, workers are all in a safe environment and do not need to be close to a strong-radioactivity environment, so that radiation hazard is avoided, and the quick-wear control valve can be safely maintained at any time. The fixed flange 1 is fixed, the lifting flange 4 and the moving flange 5 are required to be positioned with the fixed flange 1, but the positioning frequency of the lifting flange 4 is low, the positioning frequency of the moving flange 5 is high, and frequent positioning and positioning releasing operations with the fixed flange 1 and the lifting flange 4 are required. When needed, the positioning pins 2 can be completely withdrawn from the lifting flange 4 and the moving flange 5, so that complete detachment can be realized among the three flanges.
The device according to the invention is not limited to the examples described in the specific embodiments, and a person skilled in the art obtains other embodiments according to the technical solution of the invention, which also belong to the technical innovation scope of the invention.
