Summary of the invention
The utility model has overcome deficiency of the prior art, and a kind of simple in structure, fuel element gripping apparatus that is suitable for fuel element in critical or the subcritical assembly that volume is little, easy and simple to handle is provided.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme:
A kind of fuel element gripping apparatus comprises holding rod, handle, wire rope, outer tube, inner sleeve, linkage section, elastic chuck, and the middle part of handle is fixed on the holding rod, and an end of handle is connected with wire rope one end, and the other end of wire rope connects outer tube; Outer tube can endwisely slip at the effect lower edge of wire rope inner sleeve, and the top of outer tube connects spring, and the other end of spring is fixed on the inner sleeve; The inner sleeve bottom is connected with elastic chuck through linkage section.
The utility model is all right:
One end of said handle passes through a fixedly end of wire rope of steel wire pin; Behind the threaded hole of steel on the steel wire penetrating holding rod; Walk around pulley and be connected with steel wire joint pin on the outer tube, inner sleeve is provided with open slot, when sleeve pipe moves outside as the operation passage of steel wire joint pin.
The bottom of described linkage section is designed to certain angle, and this angle is that the size of based on fuel element end plug designs.
Said elastic chuck is made up of elastic steel sheet and dop.
Said pulley is fixed on the holding rod through pulley spindle.
Described dop has fillet.
Described handle is connected the back-up block of holding rod through Handle axis.
Described elastic chuck is provided with 4.
Compared with prior art, the beneficial effect of the utility model is:
The utility model takes wire rope to through the rotation of handle; Cooperation pulling outer tube through wire rope and spring moves up and down along inner sleeve; And then the folding of realization elastic chuck; Accomplish the extracting and the release of fuel element, this gripping apparatus is simple in structure, volume is little, easy to operate, is fit to the loading of fuel element in critical or the subcritical assembly and draws off.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
As shown in Figure 1; A kind of fuel element gripping apparatus; It comprises holding rod 1, handle 2, wire rope 9, outer tube 10, inner sleeve 8, spring 17, linkage section 11, elastic chuck, and the middle part of handle 2 is fastened on through Handle axis 3 on the back-up block 6 of holding rod 1, and an end of handle 2 passes through a fixedly end of wire rope 9 of pin 7; After wire rope 9 passes the threaded hole of steel 4 on the holding rod 1, walk around pulley 5 and be connected with steel wire joint pin 18.Pulley 5 adopts pulley spindle 14 to be fixed on holding rod 1 inside, and steel wire joint pin 18 is fixed on the outer tube 10.Outer tube 10 can endwisely slip along inner sleeve 8, and its top is the spring 17 that has compressed, and the upper end of spring 17 and inner sleeve boss 15 are fixing, and the upper end of lower end and outer tube 10 fixes.Inner sleeve 8 is provided with inner sleeve open slot 16, when sleeve pipe 10 moves outside as the operation passage of steel wire joint pin 18.The lower end of inner sleeve 8 is connecting linkage section 11, and the size opened with certain angle of the bottom based on fuel element end plug 20 of linkage section 11 is used to connect 4 elastic chucks.Elastic chuck as shown in Figure 2 is welded by elastic steel sheet 12 and dop 13, inwardly closes up under elastic steel sheet 12 effect of sleeve pipe 10 outside, utilizes dop 13 to grasp fuel elements 19 then.
As shown in Figure 3, the elastic chuck when grasping fuel element 19 is in and closes up state, utilizes dop 13 to mention element end plug 20, reaches the purpose that grasps fuel element 19.Dop 13 has fillet, grasps and release fuel element 19 with convenient.
The use of the utility model is following:
At first grasp holding rod 1; The handle 2 of holding with a firm grip simultaneously, then outer tube 10 moves up along inner sleeve 8, and the angle of elastic chuck is opened under the effect of linkage section 11 bottoms naturally; Hold whole gripping apparatus then and be inserted into fuel element 19 upper ends under vertical; Make the element end plug 20 of fuel element 19 get into the zone that elastic chucks contain, this moment release handle 2, then inner sleeve 8 moves down outer tube 10 in the acting force lower edge of spring 17; Force the opening angle of elastic chuck to reduce, thereby reach the purpose that grasps fuel element 19.When holding handle 2 once more with a firm grip, then outer tube 10 can inner sleeve 8 moves up in the acting force lower edge of wire rope 9, and the opening angle of elastic chuck can recover normally, thereby reaches the purpose that discharges fuel element 19.
