Description
Technical field
The utility model belongs to machinery manufacturing technology field, and in particular to a kind of annular sphere watt positioning pin dismantling tool.
Background technology
At present in K-1000-60/3000 type steam turbines, steam turbine low-pressure porthole is each configured with 8 1426545CB types
Butterfly valve, the type butterfly valve is by driving end bearing and free end bearing to support jointly, and copper bush is big inside driving end, free end bearing
Spare part must be changed by repairing, and each porthole needs to change 2 copper bushes.
In copper bush replacement process, need disintegrate driving end, free end bearing, can be related to during disintegration one compared with
For complicated and very important maintenance procedures, it is how that correct, rapidly the positioning pin between spherical bush is rested the head in dismounting watt.It presses
According to maintenance procedure requirement, surrounding dynamics need to be kept uniform when removing positioning pin, it is horizontal forward or make power backward.Due to operating area
Space is extremely narrow, and positioning pin is embedded in watt again between pillow and spherical bush, while is influenced by scene driving using in short supply, often
It is secondary that clumsy and laborious mode can only be taken to carry out when removing positioning pin.Through statistics, completing the work of a positioning pin needs to consume
When more than 1 hours, after removing positioning pin, follow-up all disintegration only need half an hour can be completed, and the plenty of time is to expend tearing open
Except on positioning pin, if in the case of according to working continuously, 16 positioning pins, which have been removed, to be needed to take 16 hours in total.It removes at present
Positioning pin work tools such as crowbar, clamp holder screwdriver, hand hammer with maintenance personal, take the mode of more violence to complete to tear open
It removes, labor intensity and work difficulty are larger.Since work difficulty, labor intensity and work deadline and repair quality are into
Direct ratio, not only allow repair quality that cannot be effectively ensured in this way, but also the repair time of overhaul main line can be delayed.
Utility model content
The utility model aim is to propose a kind of annular sphere watt positioning pin dismantling tool solve original dismounting work
The technical issues of tool is complicated, laborious, violence formula removes positioning pin, the energy while labor intensity and difficulty for mitigating maintenance personal
Positioning pin is rapidly completed and removes work.
The technical solution of the utility model is：
A kind of annular sphere watt positioning pin dismantling tool, including：Support device, positioning and locking device, stroke limit instruction
Adjustment screw, guide rod hit weight, hit weight handle and replaceable nipple；The support device upper surface setting
There is a slide-and-guide slot, one end of the guide rod is spirally connected replaceable nipple, and the other end of guide rod is spirally connected stroke limit successively
Position instruction adjustment screw and positioning and locking device；Screw thread screws positioning and locking dress to the stroke limit instruction adjustment screw other end successively
It puts, the shock weight generally hollow cylinder structure hits weight and guide rod is passed through to carry the one of replaceable nipple
It holds and is placed in slide-and-guide slot.
Weight outer surface is hit as described above and is symmetrically set with hits weight handle threads hole, the shock weight hand
Handle is spirally connected with hitting weight.
Weight central through hole aperture is hit as described above is more than guide rod outer diameter.
The conduit size of slide-and-guide slot as described above coordinates with hitting weight outer diameter.
Positioning and locking device quantity as described above is multiple, is threadedly coupled and fixes between each positioning and locking device.
Replaceable nipple and stroke limit instruction adjustment screw outer surface as described above is both provided with external screw thread.
The beneficial effects of the utility model are：
The spherical bush positioning pin dismantling tool of the utility model design, is not limited by use conditions such as spaces, easy to use,
It is easy to carry；And can realize and fast and effectively carry out firm connection with positioning pin, it is made not slipped in disassembly process；
Moreover, the spherical bush positioning pin dismantling tool of the utility model design ensure that with the uniform strength of surrounding, and along water
Square upwards remove cylindrical type positioning pin, greatly reduce because unbalance stress leads to positioning pin surface abrasion, cause bite phenomenon；
The damage of the equipment caused by violence formula dismounts is avoided, is effectively guaranteed service life of equipment；
In addition, the utility model can effectively reduce the labor intensity of staff, shorten the main line repair time, ensure that
Repair quality.
