Abstract
The utility model belongs to mechanical dismounting technical field, and in particular to a kind of nuclear power station horizontal steam generator bolt disassembling tool, comprising: driving end, handle baffle ring, handle sleeve and handle；Described handle one end is successively welded with handle sleeve and handle baffle ring；The handle other end is welded with driving end.When the utility model is to solve all kinds of closure studs of manual removal horizontal steam generator, due to the technical issues of number of bolts is more, time-consuming, effort and unbalance stress caused by the radiation of operating environment high temperature height and narrow space are easily killed.
Description
Technical field
The utility model belongs to mechanical dismounting technical field, and in particular to a kind of nuclear power station horizontal steam generator bolt is torn open
Unload tool.
Background technique
Nuclear power station horizontal steam generator maintenance, every/needs solution six top covers of sealing, removes 128 bolts, uses
The mode of manual teardown is unclamped and is fastened these bolts and not only takes time and effort, and since bolt threaded portions are longer, careless slightly
It is or firmly uneven, it is most likely that cause bolt to kill, additionally, due to working environment high temperature, high radiation, narrow space, this is to work
Development cause very big influence.
On this basis, according to the bolt arrangement of three kinds of different sizes of steam generator, according to live service condition, design
It machined a kind of bolt fastening presto tool, greatly improve operating efficiency, shorten the activity duration.
Summary of the invention
The utility model aim is to design a kind of nuclear power station horizontal steam generator spiral shell in view of the above shortcomings of the prior art
Bolt extracting tool, when solving all kinds of closure studs of manual removal horizontal steam generator, since number of bolts is more, operation ring
The technical issues of time-consuming, effort and unbalance stress caused by the radiation of border high temperature height and narrow space are easily killed.
The technical solution of the utility model is:
A kind of nuclear power station horizontal steam generator bolt disassembling tool, comprising: driving end, handle baffle ring, handle sleeve and handle
Hand；Described handle one end is successively welded with handle sleeve and handle baffle ring；The handle other end is welded with driving end.
Version as described above is integrally in " convex " type structure at hand, and version is internal at hand to be provided with and horizontal steam generator Bolt sizes
Mutually carry out matched bolt slot.
Handle as described above is integrally in " Z " font structure；The handle other end is welded on version center of top at hand.
Driving end, handle baffle ring, handle sleeve and handle as described above are that stainless steel material is made.
The utility model has the following beneficial effects:
A kind of nuclear power station horizontal steam generator bolt disassembling tool of the utility model design, is used for the horizontal steaming of nuclear power station
The fast quick-detach of vapour generator bolt, fastening, structure is simple, easy to use；The utility model can effectively solve the problem that nuclear power station
The Bolt dismantling of horizontal steam generator, fastening time-consuming, effort, easy the problem of killing, working efficiency is greatly improved, is shortened
Operate the activity duration of maintenance personal.
Detailed description of the invention
Fig. 1 is a kind of structural representation of nuclear power station horizontal steam generator bolt disassembling tool designed by the utility model
Figure；
A kind of version of nuclear power station horizontal steam generator bolt disassembling tool designed by Fig. 2 the utility model is overlooked at hand
Figure.
Wherein, 1-driving end；2-handle baffle rings；3-handle sleeves；4-handles.
Specific embodiment
A kind of nuclear power station horizontal steam generator bolt disassembling tool of the utility model is described further below:
As shown in Figure 1, 2, a kind of nuclear power station horizontal steam generator bolt disassembling tool, comprising: driving end 1, retaining lever catch
Ring 2, handle sleeve 3 and handle 4；Described 4 one end of handle is successively welded with handle sleeve 3 and handle baffle ring 2；The welding of 4 other end of handle
There is driving end 1.
The whole driving end 1 is in " convex " type structure, is provided with and horizontal steam generator Bolt sizes phase inside driving end 1
Carry out matched bolt slot.
The whole handle 4 is in " Z " font structure；4 other end of handle is welded on 1 center of top of driving end.
The driving end 1, handle baffle ring 2, handle sleeve 3 and handle 4 are that stainless steel material is made.
In use, select the driving end 1 of corresponding specification according to different size bolt, according to steam generator bolt appearance and
Size has opened the bolt slot coincideing with Bolt sizes in driving end 1.
During disassembly is with fastening bolt, no longer needs to manually tighten and looser a bolt, it only need to be by the utility model tool
After being mounted on bolt, rotating handles 4, so that it may power be uniformly transferred to bolt by lever principle, realized quick, steady
The possibility of fixed, safe assembling-disassembling bolt.
The utility model is explained in detail above in conjunction with embodiment, but the utility model is not limited to above-mentioned implementation
Example, within the knowledge of a person skilled in the art, can also be in the premise for not departing from the utility model aims
It is lower that various changes can be made.The content being not described in detail in the utility model can use the prior art.
