Abstract
The invention discloses a kind of non-integral pouring type generator unit outlet casing tube locknuts to load and unload specific purpose tool, including：Tool body, adjustment bolt, handle, the tool body are the annulus made of No. 45 steel entirety turning, are highly no more than the height of outlet casing tube locknut；8 through-holes are evenly arranged on the side wall circumference of the tool body, wherein tetra- bore dias of A, B, C, D are the screw hole of φ 16mm, remaining four bore dia is φ 20mm；The handle is four, length 250mm, φ 20mm, is respectively welded in four holes that diameter is φ 20mm；The adjustment bolt is threadedly engaged with the screw hole that diameter is φ 16mm.Power when screwing locknut, is spared to using specific purpose tool, gasket uniform force, each position decrement is uniform, and gasket bears the maximum moment that pressure does not exceed its plastic deformation, reaches excellent sealing effect.
Description
Technical field
The invention belongs to the station-service apparatus field that generates electricity, specifically outlet casing tube locknut loads and unloads specific purpose tool, more has
Saying for body is non-one-piece casting formula generator unit outlet casing tube locknut handling specific purpose tool, and outlet casing tube refers to generator unit stator
Electric current guides to the important component outside machine from generator, in addition to it should be able to bear certain Hydrogen Vapor Pressure, should be able to also bear high electricity
Pressure, high current simultaneously have sealing, antivibration and moisture-proof superperformance.
Background technique
The set generator outlet casing tube of Zhangjiakou power plant 1 to 8 belongs to eastern electric early production, using non-integral pouring type
Structure, casing carry out sealed electric generator internal hydrogen by gasket and do not leak, but with the increase for time of putting into operation, generator outlet
Bobbin seal pad is influenced gradually aging by high temperature and greasy dirt, leakage hydrogen phenomenon occurs, although stopping standby host meeting using maintenance or unit
Gasket is replaced, but since technique when loading and unloading casing every time is lack of standardization, is inserted into latch nut hole with a curved bolt, then with hammering into shape
Son taps bolt, and locknut is made to screw or unclamp, this loading and unloading capacity is lack of standardization to cause very short time interior repetition after gasket replacement to send out
Raw casing leaks hydrogen, results in waste of resources, and leakage hydrogen seriously also occurs that hydrogen is quick-fried, threatens the safety of the person and equipment.For this defect,
Our special casing locknut handling instrument customized, after replacing gasket, when nut-locking, spares to power, gasket by
Power is uniform, and each position decrement is uniform, and gasket bears the maximum moment that pressure does not exceed its plastic deformation, reaches good close
Envelope effect.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, and provide it is a kind of it is simple in construction, easy to disassemble and assemble, avoid it is sudden and violent
Power forcible entry causes outlet casing tube close
The non-integral pouring type generator unit outlet casing tube locknut of packing damage loads and unloads specific purpose tool.
For achieving the above object, this practical heads west adopts the following technical scheme that realization：The power generation of non-integral pouring type
Machine unit outlet casing tube locknut loads and unloads specific purpose tool, including：Tool body, adjustment bolt, handle, the tool body are with No. 45
Annulus made of steel entirety turning, the thickness of internal diameter to outer diameter are not less than 25mm, and internal diameter is greater than the outer diameter of outlet casing tube locknut
2mm is highly no more than the height of outlet casing tube locknut；8 through-holes are evenly arranged on the side wall circumference of the tool body,
Tetra- bore dias of middle A, B, C, D are the screw hole of φ 16mm, remaining four bore dia is φ 20mm；The handle is four, long
Degree is 250mm, φ 20mm, is respectively welded in four holes that diameter is φ 20mm；The adjustment bolt and diameter is φ
The screw hole of 16mm is threadedly engaged；The diameter of the adjustment bolt is less than the aperture of A ' B ' C ' D ' on outlet casing tube locknut, disassembly
Specific purpose tool is covered outside outlet casing tube locknut when locknut, four screw holes is made to be aligned four holes of outlet casing tube locknut respectively, and
Adjustment bolt is screwed with the bolt of φ 16, the hole for four A ' B ' C ' D ' for allowing the end of adjustment bolt to be caught in outside outlet casing tube locknut
It is interior；Staff symmetrically catches operating stick to screw or unclamp outlet casing tube locknut at this time.Staff is firmly uniform in this way, when
When two people operate motionless outlet casing tube locknut, just gasket decrement reaches optimal seal effect at this time.
The present invention has：Advantage simple in construction, easy to disassemble and assemble, convenient for safeguarding effectively extends outlet casing tube locknut
With the service life of gasket.

Specific embodiment
Illustrate with reference to the accompanying drawing, the present invention is further elaborated.
FIG. 1 to FIG. 4 is preferred embodiment of the invention, and which show non-integral pouring type generator unit outlet casing tube locknuts
Specific purpose tool is loaded and unloaded, including：Tool body, adjustment bolt, handle, the tool body are the circle made of No. 45 steel entirety turning
Ring, the thickness of internal diameter to outer diameter are not less than 25mm, and internal diameter is greater than the outer diameter 2mm of outlet casing tube locknut, are highly no more than outlet
The height of casing locknut；8 through-holes are evenly arranged on the side wall circumference of the tool body, wherein tetra- Kong Zhi of A, B, C, D
Diameter is the screw hole of φ 16mm, remaining four bore dia is φ 20mm；The handle is four, length 250mm, φ 20mm,
It is respectively welded in four holes that diameter is φ 20mm；The adjustment bolt is threadedly engaged with the screw hole that diameter is φ 16mm；
The diameter of the adjustment bolt is less than the aperture of A ' B ' C ' D ' on outlet casing tube locknut, covers specific purpose tool when dismantling locknut
Outside outlet casing tube locknut, four screw holes are made to be aligned four holes of outlet casing tube locknut respectively, and screw adjustment with the bolt of φ 16
Bolt, in the hole for four A ' B ' C ' D ' for allowing the end of adjustment bolt to be caught in outside outlet casing tube locknut；Staff is symmetrical at this time
Operating stick is caught to screw or unclamp outlet casing tube locknut.Staff is firmly uniform in this way, when two people operate motionless lead collar
When pipe locknut, just gasket decrement reaches optimal seal effect at this time.
The tool application replaces gasket in the unit maintenance of Zhangjiakou power plant 1 to 8（102）It is sufficiently tested in work
Card, will not lead to gasket because construction technology is lack of standardization（102）Poor sealing occurs hydrogen and leaks defect.
