Description
Technical field
The invention belongs to electrical equipment technical fields, are related to a kind of shaft bearing replacer.Background technique
In disconnecting switch maintenance process, since disconnecting switch long term outdoor runs exposing to the weather, various severe days are born
Gas cut erosion.Cause disconnecting switch supporting bearing clamping stagnation, corrosion can not normal operating operation.The appearance of this problem not only makes to be isolated
Switch is not normally functioning, especially in switch operation, since supporting bearing clamping stagnation, corrosion cause disconnecting link position often cannot
It is primary to close in place.Cause frequent operation, the multiple arcing of contact in switch operation makes contact aoxidize poor contact, or even causes to touch
Head is burnt.Increase unnecessary economic loss.Keep the operating time too long simultaneously, especially in incident processing procedure, extends not
Necessary power off time, influences power supply reliability.The disassembly common tool of usual support upper bearing (metal) is the common Three-claw type in market
Puller.Because support upper bearing (metal) and upper bracket spacing are too small, and there is an iron sheet sheath.Three-jaw can not be caught in, thus cannot be smooth
Dismantle this bearing.Sometimes because corrode the time is long, disassembly is difficult, maintenance time too long influence power supply reliability due to replace whole group knife
Lock.Cause overhaul efficiency low, the wasting of resources.In maintenance practice process for a long time, gradually processes, invented such special bearing and tear open
Unload tool.
Summary of the invention
The technical problems to be solved by the present invention are: providing a kind of shaft bearing replacer, it can be realized and fast and safely dismantle
The bearing facilitates electric power overhaul personnel.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of shaft bearing replacer, containing stripper plate, stay-bolt, top plate, lead screw mandril, the lead screw mandril is mounted on top
The middle part of plate, towards stripper plate, the stripper plate is connect by stay-bolt with top plate, and the stripper plate is split two
Block is equipped with circular hole at the middle part of two pieces of opposite joints, is connected by fastening bolt to tight between two stripper plates.
Wedge-shaped edge is equipped in the circular hole.
The mandril tail portion is equipped with handle.
The mandril front end is conical head.
The beneficial effects of the present invention are:
The present invention stripping attachment, small in size, structure is simple, at low cost, is convenient for outdoor operations, easy to use, especially needle
It is more suitable to the bearing removal of GW Series Switch-disconnector bottom, can be realized and fast and safely dismantle the bearing, facilitate electric power
Service personnel.
Detailed description of the invention
Fig. 1 the structural representation of present invention.
Wherein, 1. stripper plates, 2. fastening bolts, 3. stay-bolts, 4. top plates, 5. mandrils, 6. handles, 7. circular holes in figure.
Specific embodiment
As shown in Figure 1, shaft bearing replacer of the invention, contains stripper plate, stay-bolt, top plate, lead screw mandril, the silk
Thick stick mandril is mounted on the middle part of top plate, and towards stripper plate, the stripper plate is connect by stay-bolt with top plate, and described squeezes
Pressing plate is split two pieces, is equipped with circular hole at the middle part of two pieces of opposite joints, passes through fastening bolt connection pair between two stripper plates
Tightly.Wedge-shaped edge is equipped in the circular hole.The mandril tail portion is equipped with handle.The mandril front end is conical head.Institute
The two pieces of stripper plates stated run through bolt hole equipped with corresponding, and the fastening bolt is installed through the bolt hole.The drawing
Bar bolt is four, is symmetricly set on the surrounding of circular hole.
The circular hole correspondence of above-mentioned two pieces of stripper plates is buckled between split bearing and the gap of its positioning surface, it is tight by tightening
Fixing bolt gradually approaches two pieces of stripper plates, and the wedge-shaped edge in the circular hole is inserted into the gap of bearing Yu its positioning surface
It is interior, until the complete opposite joint fastening of two stripper plates, the spindle nose upper ejector pin of GW Series Switch-disconnector is then pressed against by rotation, is driven
Dynamic top plate, stay-bolt, and stripper plate is driven, split shaft is born into out spindle nose.
The present invention stripping attachment, small in size, structure is simple, at low cost, is convenient for outdoor operations, easy to use, especially needle
It is more suitable to the bearing removal of GW Series Switch-disconnector bottom, can be realized and fast and safely dismantle the bearing, facilitate electric power
Service personnel.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to the foregoing embodiments
Invention is explained in detail, those skilled in the art should understand that: it still can be to previous embodiment
Documented technical solution is modified or equivalent replacement of some of the technical features；And these are modified or replace
It changes, the spirit and scope for technical solution of the embodiment of the present invention that it does not separate the essence of the corresponding technical solution.
