1 control rod guide tube wherein, 2 lower subs, 3 sunk screws, 4 carbines, 5 times sockets even, 6 grooves, 7 carbine bodies, 8 coupler bodies, 9 inclined-plane projections, 10 carbine jacks, 11 gathering sills, 12 bases, 13 rectangular openings, 14 screws.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment is described further.
Present embodiment discloses applied a kind of control rod guide tube stationary installation in the Chinese advanced research reactor (CARR), as shown in Figure 1, comprise the control rod guide tube lower end lower sub 2, and down connect socket 5, described lower sub 2 is inserted down and is connected socket 5, thus realization fixing to control rod guide tube.
The described structure that connects down socket 5 as shown in Figure 7 and Figure 8, integral body is the octagon tubular structure, inboard is an octagon on it, the inboard, lower end is cylindric.The upper end has gathering sill 11 and the carbine jack 10 that is positioned on the same axis on four sides separately, and the size of its size and carbine 4 is complementary, and the position is positioned on the center line of this side.
The lower sub 2 of described control rod guide tube is made by 6061 aluminium, is fixed by welding in the lower end of control rod guide tube 1.Described lower sub 2 is divided into three sections, and to shown in Figure 5, epimere is the middle rectangular shape that has cylinder as Fig. 2, and the stage casing is an octagon, and hypomere is cylindric.The stage casing of lower sub 2 and the size of hypomere are complementary with the interior octagon that connects socket 5 upper ends down, guarantee the accurate position of control rod guide tube, as shown in Figure 8.Described lower sub 2 stage casings respectively have a rectangular opening 13 on four sides separately, and described rectangular opening 13 tops are provided with screw 14.Carbine 4 by screw retention in rectangular opening 13 outsides.
As Fig. 9 and shown in Figure 10, described carbine 4 is made up of carbine body 7 and coupler body 8, and described carbine body 7 is provided with screw, and there is inclined-plane projection 9 described coupler body below.The inclined-plane of projection 9 upper ends, described inclined-plane is from the horizontal by the α angle, and the inclined-plane of lower end is in vertical direction with the β angle.Described α angle and β angle are calculated according to the firmly size in when installation and removal and are determined, the strength that needs in the time of can not making loading and unloading is too big and damage lower sub, can not make bed knife too little and cause the fixing not firm of control rod guide tube.The length l of coupler body and thickness t through calculating, guarantee can not cause the plastic yield of carbine 4 equally in the control rod guide tube cargo handling process.
When mounted, carbine 4 is aimed at the gathering sill 11 that connects down on the socket 5, add certain pressure, make inclined-plane projection 9 bullets of coupler body 8 lower ends advance the carbine jack 10 that connects down on socket 5 madial walls, with the A/C lower end.During dismounting, upwards apply about 80kg pulling force, coupler body 8 is pulled out down connect socket 5, propose control rod guide tube, easy to operate.
Above content be in conjunction with preferred embodiment to specifying that the utility model is done, can not assert that embodiment of the present utility model only limits to these explanations.Concerning the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deductions and conversion, all should be considered as belonging to protection domain of the present utility model.
