Preferably, rubber is wrapped up in the outer surface of the horizontal hook foot.
Description of the drawings
Fig. 1 is the schematic diagram of the extracting tool of the steel skeleton gasket of the utility model.
Specific implementation mode
The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings.
In conjunction with shown in Fig. 1, the extracting tool of the steel skeleton gasket of the utility model include supporting rod 10, terminal pad 20,
Movable hook foot 30, connecting rod 40, hollow disc 50 and spring 60.
Supporting rod 10 is elongated round bar, and terminal pad 20 is set in the top periphery of supporting rod 10 and is fixed with supporting rod 10
Connection.The quantity of movable hook foot 30 is 3；The top of movable hook foot 30 is brace 31, and intermediate position is vertical bar, and lower part is equipped with
Horizontal hook foot 32；Be laid with 3 the first U-type grooves on the outer circumference surface of terminal pad 20, brace 31 by the first U-type groove with connect
Disk 20 is hinged.Hollow disc 50 is set in the middle part of supporting rod 10, and can be moved back and forth along the axis direction of supporting rod 10；In
3 the second U-type grooves are laid on the outer circumference surface of blank panel 50.The quantity of connecting rod 40 is also 3, and connecting rod 40 is elongate rod
One end of shape, connecting rod 40 is provided with third U-type groove and, connecting rod hinged by third U-type groove and the vertical bar of movable hook foot 30
40 other end is hinged by the second U-type groove and hollow disc 50, and connecting rod 40 and the articulated position of vertical bar are consistently higher than
The articulated position of connecting rod 40 and hollow disc 50.The bottom of supporting rod 10 is equipped with pedestal 12, and spring 60 passes through supporting rod 10, is set to
Between pedestal 12 and hollow disc 50, it is used to support hollow disc 50.
In the present embodiment, 3 the first U-type grooves are laid on the outer circumference surface of terminal pad 20, equally, in other realities
It applies in example, can also first U-type groove of other quantity, such as four be set according to the size of steel skeleton gasket to be removed
A or five, to increase contact point of the movable hook foot with steel skeleton gasket, raising contacts steady with steel pipe frame gasket
It is qualitative, ensure the steady of disassembly process.
The extracting tool of steel skeleton gasket according to the present utility model, when needing to dismantle to steel skeleton gasket
When, hollow disc 50 is pressed downward first, spring 60 can be compressed, while hollow disc 50 drives connecting rod 40 to move downward, and be connected
Bar 40, which moves downward, can be such that movable hook foot 30 is tightened to centre；When movable hook foot 30 is tightened to 3 32 outer end of horizontal hook foot compositions
Circular diameter be less than steel skeleton gasket inner ring diameter when, then by horizontal hook foot 32 pass through steel skeleton gasket inner ring；It connects
Get off to unclamp hollow disc 50, under the elastic force effect of spring 60, hollow disc 50 can move upwards, while drive connecting rod 40 upward
Movement, connecting rod 40, which moves upwards, can be such that movable hook foot 30 opens around, until the vertical bar position of movable hook foot 30 and steel
The inner ring of reinforced seal pad is adjacent to；Then the upper end of supporting rod 10 is lifted up, horizontal hook foot 32 and steel skeleton gasket
End face can contact and be adjacent to；Further supporting rod 10 is carried upwards, horizontal hook foot 32 can apply pressure simultaneously to steel skeleton gasket
Finally steel skeleton gasket is pulled out from electrical header ontology.
The extracting tool of the steel skeleton gasket of the utility model can be sealed steel skeleton by simple a few step operations
Pad is completely removed from electrical header ontology, compared to the method that destructiveness is removed, can greatly save the take-down time；Work as environment
In when emitting high levels of radiation, the dismantlement work of steel skeleton gasket can also be completed in the short time, to reduce operating personnel in high spoke
It penetrates the residence time in environment, reduces the injury of Radiation On Human body；Also, tool will not touch electrical header sheet in disassembly process
Body, to be damaged to electrical header ontology.
Preferably, external screw thread 11 is set on the top periphery of supporting rod 10, the spiral shell in the inner ring setting of terminal pad 20
Line, the mode that terminal pad 20 is connected through a screw thread are connect with supporting rod 10.By the way of threaded connection, terminal pad 20 is supporting
Position on bar 10 can be with up and down adjustment.The pulling force needed when steel skeleton gasket is dismantled is larger, and the elastic force of spring 60 is insufficient
So that movable hook foot 30 is flared out, it is possible that the case where horizontal hook foot 32 skids off steel skeleton gasket.It at this time will be even
It connects position of the disk 20 on supporting rod 10 to adjust downwards, the position of hollow disc 50 also accordingly moves down, the decrement of spring 60
Become larger, elastic force increases, it is possible to provide removal force also bigger.
Preferably, one handle 70 is set in the upper end of supporting rod 10, adding handle 70 makes the operation for lifting supporting rod 10 become
Must be more convenient, increase convenience when dismounting.
Preferably, rubber is wrapped up in the outer surface of horizontal hook foot 32, in this way can be when dismantling steel skeleton gasket, to reinforcing bar
The damage smaller of frame gasket, what the sealing of intact steel skeleton was lined under dismounting can be continuing with, to save resource.
