Embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in Figures 1 to 8, the utility model steam turbine rear bearing cover dismounting special spanner, including sleeve 1 and handle 2,
The both ends of sleeve 1 are provided with plum blossom-shaped endoporus 11, and the handle 2 is Telescopic rod structure, and the one end of handle 2 and sleeve 1
Outer middle side part connection.It will be appreciated to those of skill in the art that the present apparatus is provided with plum blossom-shaped endoporus at the both ends of sleeve 1
11, it is arranged to expansion link for being socketed locking nut, while by handle 2.When in use, can according to the pretightning force of different bolts,
The length of regulation handle 2 acts on so as to reach increase arm of force labour-saving；Due to the gap and angle of jiggering lid and steam turbine cylinder
It is smaller, tend not to rotary handle 2 always and unscrew nut, therefore actually use when, when handle 2 can not rotate, then need by
Sleeve 1 overturns 180 °, then the other end of sleeve 1 is inserted in into nut, is rotated further handle 2, such Reusability, until nut
Tighten or unscrew.
Preferably, handle 2 described in said apparatus is detachably connected with sleeve 1.Skilled artisans appreciate that
It is that the present apparatus is that further preferred handle 2 is detachably connected with sleeve 1, this structure setting when not in use, can be by handle 2
Remove, occupy little space with sleeve 1, be easy to outgoing carrying.
Preferably, the fixed part 12 of flanged structure is provided with the middle part of the outer wall of sleeve 1 described in said apparatus, close to fixed part
The connecting portion 13 of outer hexagonal structure is provided with 12 two lateral wall circumferences；The one end of handle 2 is provided with the interior hexagonal hole of adaptation
21.It will be appreciated to those of skill in the art that the present apparatus is the connected mode of further preferred handle 2 and sleeve 1, specifically
It is the fixed part 12 that flanged structure is set in the middle part of the outer wall of sleeve 1, and outer six sides is not provided with the outer wall of both sides close to fixed
The connecting portion 13 of structure, while the end set of handle 2 had into interior hexagonal hole 21, can be directly by the one end of sleeve 1 during actual use
Nut is inserted in, then handle 2 is inserted in the connecting portion 13 of flange upper end, and fixed part 12 can be prevented effectively in nutting,
Handle 2 glides and causes to damage, while increases the arm of force, and use is more laborsaving.
