Abstract
The utility model provides a bearing disassembling device for a GW series isolating switch, which comprises two extruding plates, a screw bolt of a pull rod, a top plate and a mandril of a screw rod, wherein the mandril of the screw rod is arranged in the middle of the top plate and faces the extruding plates; the extruding plates are connected with the top plate by the screw bolt of the pull rod; the two extruding plates are opened opposite to each other; a circular hole is arranged in the middle of the opposite joint of the two extruding plates; and the two extruding plates are connected tightly by a plurality of fastening bolts. The device is small in volume, simple in structure, low in cost, convenient for outdoor operation, convenient for use, particularly more suitable for disassembling the bearing at the bottom of the GW series isolating switch, capable of fast and safely disassembling the bearing, and convenient for the power maintenance staff.
Description
Technical field
The utility model relates to the service technique field of power supply equipment, particularly relates to a kind of GW Series Switch-disconnector shaft bearing replacer.
Background technology
In the power system GW Series Switch-disconnector maintenance process,, bear various bad weathers and corrode because the long-term outdoor operation of isolating switch is exposed to the weather.Cause isolating switch supporting bearing clamping stagnation, corrosion normal running to move.The appearance of this problem not only makes isolating switch normally not move, particularly when switch operation, owing to supporting bearing clamping stagnation, corrosion cause the disconnecting link position often can not once be incorporated into the position.Cause operation frequent, repeatedly arcing of contact in the switch operation makes contact oxidation loose contact, even causes contact to burn.Increase unnecessary economic loss.Make the operating time long simultaneously, particularly in the accident treatment process, prolong unnecessary power off time, influence power supply reliability.Usually the dismounting common tool of bearing upper bearing (metal) is the three-jaw type puller that market is common.Because of bearing upper bearing (metal) and upper bracket spacing are too little, and an iron sheet sheath is arranged.Three-jaw can't snap in, thereby can not dismantle this bearing smoothly.Sometimes long because of the corrosion time, dismounting difficulty, maintenance time, the long power supply reliability that influences was changed whole group disconnecting link.Cause overhaul efficiency low, the wasting of resources.In long-term maintenance practice process, progressively process, invented this kind special bearing extracting tool.
The utility model content
The purpose of this utility model is in order to address the above problem, a kind of GW Series Switch-disconnector shaft bearing replacer to be provided
The technical solution of the utility model is: GW Series Switch-disconnector shaft bearing replacer, contain stripper plate, stay-bolt, top board, leading screw push rod, described leading screw push rod is installed in the middle part of top board, towards stripper plate, described stripper plate is connected with top board by stay-bolt, described stripper plate is two that split, and is provided with circular hole at the middle part of two opposite joints, connects tightly by fastening bolt between two stripper plates.
Be provided with the wedge shape edge in the described circular hole.
Described push rod afterbody is provided with handle.
Described push rod front end is a conical head.
Described two stripper plates are provided with corresponding through bolt hole, and described fastening bolt runs through this bolt hole to be installed.
Described stay-bolt is four, be symmetricly set on circular hole around.
The beneficial effects of the utility model
This stripping attachment, volume is little, and is simple in structure, and cost is low, is convenient to outdoor operation, and is easy to use, particularly more suitable at the bearing removal of GW Series Switch-disconnector bottom, can realize this bearing of dismounting fast and safely, makes things convenient for the electric power overhaul personnel.

Fig. 2 is the plan structure schematic diagram of Fig. 1;
Fig. 3 is this GW Series Switch-disconnector shaft bearing replacer user mode structural representation.
The specific embodiment
Referring to Fig. 1-Fig. 3,1. stripper plates among the figure, 2. fastening bolt, 3. stay-bolt, 4. top board, 5. push rod, 6. handle, 7. circular hole, 8. porcelain spare, 9. split bearing, the 10. spindle nose of GW Series Switch-disconnector of GW Series Switch-disconnector.
Embodiment: a kind of GW Series Switch-disconnector shaft bearing replacer among the figure, contain stripper plate, stay-bolt, top board, leading screw push rod, described leading screw push rod is installed in the middle part of top board, towards stripper plate, described stripper plate is connected with top board by stay-bolt, described stripper plate is two that split, and is provided with circular hole at the middle part of two opposite joints, connects tightly by fastening bolt between two stripper plates.Be provided with the wedge shape edge in the described circular hole.Described push rod afterbody is provided with handle.Described push rod front end is a conical head.Described two stripper plates are provided with corresponding through bolt hole, and described fastening bolt runs through this bolt hole to be installed.Described stay-bolt is four, be symmetricly set on circular hole around.
Use:
According to shown in Figure 3, the circular hole correspondence of above-mentioned two stripper plates is buckled between the slit of split bearing and its locating surface, by tightening fastening bolt that two stripper plates are progressively approaching, wedge shape edge in the described circular hole is inserted in the slit of bearing and its locating surface, fastening up to two complete opposite joints of stripper plate, by the spindle nose upper ejector pin of rotation roof pressure, drive top board, stay-bolt then in the GW Series Switch-disconnector, and the driving stripper plate, split shaft is born out spindle nose.
