Abstract
The utility model relates to a kind of generator outlet sleeve pipe locknut handling instrument, is made up of dop, annular anchor ear and handle, and described annular anchor ear is the metal plate structure of annular, and this annular anchor ear end arranges handle, annular anchor ear leading inside fixed installation dop; The utility model beneficial effect is: the structure improving existing handling instrument, make it to form a kind of handling instrument that can be used in generator outlet sleeve pipe locknut, coordinating and arranging with handle same plane by dop and annular anchor ear, when can solve the handling of generator outlet sleeve pipe locknut, the problem of not easily exerting oneself in little space.
Description
Technical field
The utility model relates to power domain, particularly relates to the generator outlet sleeve pipe locknut handling instrument of a kind of generator maintenance, special replacement.
Background technology
Due to the difference of industry field, tool construction and the purposes of the same type that power industry and machinery industry adopt are also different, such as, for the instrument of nut installation and removal.
The generator outlet sleeve pipe locknut external diameter of current electrical machinery plant 200MW is comparatively large and surrounding space is limited, only by existing general tool, difficulty be installed and cannot position be attached it to, bobbin seal will be caused not tight, be in operation and may produce the seepage of hydrogen, the stable operation of harm unit safety.
Authorization Notice No. is CN 202029068 U and the Chinese patent that the patent No. is 201120098980.5 discloses a kind of carriage locking nut wrench, a large footpath cylinder coaxially connects a path cylindrical drum, cylindrical outer face, large footpath there is interior hexagonal hole, path cylindrical outer tube end cylinder has radial direction through hole; This structure fabrication is simple, be convenient to make, be convenient to install and use, but cannot remove thread casing locknut.
Authorization Notice No. is CN 203993724 U and the Chinese patent that the patent No. is 201420436432.2 discloses the provision for disengagement of a kind of centrifuge disc spring locknut, and the center of base is provided with centre bore; Multiple fixture block, described fixture block is distributed on the side of described base, and described fixture block is used for being plugged in the groove of locknut respectively; Spanner, comprises driving head, and described driving head is fixedly connected with described centre bore; Spanner is fixed by arranging centre bore on base, be stuck in the groove of locknut by arranging fixture block on base, when needs dismounting locknut, a people is only needed to be stuck on locknut by this provision for disengagement, starting spanner drives base and fixture block to rotate, thus locknut is screwed off, reach the object of dismounting locknut.This structure just can avoid the damage of locknut, but due to volume excessive, cannot put in and remove thread casing locknut.
Authorization Notice No. is CN203981428 U, the patent No. be 201420185021.0 Chinese patent disclose a kind of sampler, comprise interior pipe and outer tube, described interior pipe is arranged on outer tube, interior pipe plugs with outer tube and is connected, described interior pipe and outer tube are equipped with grooving, and the length of described outer tube grooving is 3/4 of outer length of tube; The girth of described outer tube grooving is 3/5 of outer tube girth; The length of described interior pipe grooving is 3/4 of inner tube length; The girth of described interior pipe grooving is 3/5 of interior pipe girth.The problem that this patent pipe mainly solves is, closes to close into a pipe and sample after can rotating 180 ° within the outer tube with outer tube, and structure is simple, easy to operate; Meanwhile, this structure by the impact of moisture content of material, can not sampled by any material, can be improved the degree of accuracy of sampling widely.But this structure clearly only can extract a sample, cannot realize Stratified Sampling.
As known from the above, existing instrument cannot implement the dismounting of generator outlet sleeve pipe locknut, therefore, for above aspect, needs reasonably to improve prior art.
Utility model content
For above defect, the utility model provides the generator outlet sleeve pipe locknut handling instrument that a kind of handling safety is convenient, structure simple, can carry out stratified sampling, can improve calcium lime powder material Detection job, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of generator outlet sleeve pipe locknut handling instrument, be made up of dop, annular anchor ear and handle, described annular anchor ear is the metal plate structure of annular, and this annular anchor ear end arranges handle, annular anchor ear leading inside fixed installation dop;
Correspondingly, dop is welded the one end in annular anchor ear edge, and handle is welded in the outer of the annular anchor ear other end, and handle and dop remain in same plane.
In addition, described annular anchor ear internal diameter is slightly larger than the external diameter of outlet casing tube nut;
Described dop blocks the screw of outlet casing tube locknut, directly drives locknut, and annular anchor ear fits tightly with outlet casing tube locknut outer after dop enters screw.
The beneficial effect of generator outlet sleeve pipe locknut handling instrument described in the utility model is: the structure improving existing handling instrument, make it to form a kind of handling instrument that can be used in generator outlet sleeve pipe locknut, coordinating and arranging with handle same plane by dop and annular anchor ear, when can solve the handling of generator outlet sleeve pipe locknut, the problem of not easily exerting oneself in little space.

In figure:
1, dop; 2, annular anchor ear; 3, handle.
Detailed description of the invention
As Figure 1-4, generator outlet sleeve pipe locknut handling instrument described in the utility model embodiment, by dop 1, annular anchor ear 2 and handle 3 form, the toroidal metal plate structure that described annular anchor ear 2 is made up of alloy, at annular anchor ear 2 end, handle 3 is set so that firmly, at fixing for outlet casing tube nut of annular anchor ear 2 leading inside fixed installation dop 1, time fixing, lever principle can be utilized, outlet casing tube nut uniform stressed is rotated, dop 1 length wherein makes according to sleeve pipe locknut diameter and the degree of depth, annular anchor ear 2 internal diameter is slightly larger than the external diameter of outlet casing tube nut, the length of handle 3 is determined according to periphery of spigot space, to guarantee ease of use.
Generator outlet sleeve pipe locknut handling instrument described in above the utility model embodiment, structure is based on annular anchor ear 2, dop 1 is welded the one end in annular anchor ear 2 edge, and handle 3 is welded in the outer of annular anchor ear 2 other end, overallly keeps in one plane.During use, dop 1, for blocking the screw of sleeve pipe locknut, directly will drive locknut, and annular anchor ear 2 fits tightly with locknut outer after dop 1 enters screw, plays point action; Handle 3 can lengthen moment, makes operation more laborsaving, when whole instrument uses should with sleeve pipe median perpendicular, be convenient to firmly and prevent side force from damaging sleeve pipe.
The above-mentioned description to embodiment can understand and apply this case technology for the ease of those skilled in the art, person skilled in the art obviously can make various amendment to these examples easily, and General Principle described herein is applied in other embodiment and need not through performing creative labour.Therefore, this case is not limited to above embodiment, and those skilled in the art is according to the announcement of this case, and the improvement made for this case and amendment all should in the protection domains of this case.
