Description
Technical field
The present invention relates to a kind of box spanners for limiting fitted position.
Background technique
Disconnecting switch is as a kind of open type electric product, and volume is larger and heavier mass, this makes disconnecting switch
Transportation cost is higher and transportational process in safety it is poor, in the prior art in order to reduce the transportation cost of disconnecting switch, protect
The safety for demonstrate,proving transportational process generallys use the mode of seperated transport.So-called seperated transport be intra-company only complete every
Then these components in bulk are transported to power station by the substantially assembly for leaving the assembly and remaining components of closing main switch knife,
The whole assembly of disconnecting switch is completed in power station again.
Many components in bulk can be generated by the way of fission transport, site operation personnel is referred to as these in company
Completion is substantially assembled, and the components for carrying out general assembly again after transporting to power station are to deposit stackware.Stackware is deposited by several small parts substantially
It is assembled, to avoid the case where being not easy to unscrew and causing small part to lose during transportation occur in power station, these are small
It is appropriate that fastening force of the part in assembly needs, and avoids assembling too tight or too loose situation as far as possible.Such as GW16-252 high pressure
Positioning sleeve component in AC isolation switch（I.e. one kind deposits stackware）Assembly, as shown in Figure 1, positioning sleeve component includes positioning sleeve 1
And be mounted on the bolt 2 on positioning sleeve 1, in order to facilitate positioning sleeve component transport the further fastening to power station assembly and
Prevent bolt 2 from losing during transportation, bolt 2, which should be installed when the distance to bolt head away from 1 outer surface of positioning sleeve is H, to be advisable.
In addition, further including shaft coupling board group part in GW16-252 high-voltage alternating current isolating switch（Another kind deposits stackware）Assembly, such as Fig. 2 institute
Show, shaft coupling board group part includes shaft coupling plate 11, pressing plate 12 and the two is installed to fixed bolt 2, after reaching power station for convenience
With the assembly of steel pipe, bolt 2, which should be installed when the lateral surface to bolt head away from shaft coupling plate 11 is L, to be advisable.
The above-mentioned installation for depositing stackware is generally deposited in the prior art using box spanner to install in company for convenience
Bolt in stackware, but box spanner in the prior art only has the function of fastening, screws depth without limitation bolt
The function of degree, engineering can only rely on experience and the observation of operator to determine the thread depth of bolt, this dress in practice
With mode, time-consuming and laborious and labor intensity is high, assembly efficiency is low.Further, since bolt is when screwing in root, drive sleeve spanner
Motor can't shut down immediately, the components that operator holds（Positioning sleeve and shaft coupling plate）It also can be with driving motor
Rotation and rotate, be easy assembler is damaged, be unfavorable for assembly when safety work.
Summary of the invention
The purpose of the present invention is to provide a kind of box spanners for limiting fitted position, for solving prior art middle sleeve
The technical issues of spanner cannot be defined the screw-in depth of bolt.
To achieve the above object, the box spanner of restriction fitted position of the invention（Hereinafter referred to as box spanner）Using such as
Under technical solution：
It is provided with the transmission connecting structure for being sequentially connected with driving device on front side of box spanner, is set on rear side of box spanner
It is equipped with mating with bolt and provides the grafting drive mechanism of torsional moment to bolt, be additionally provided on rear side of box spanner
Bolt screws in after set depth size for contacting with the setting surface press on the installation part for assembling the bolt so as to rotate
Bolt and the grafting drive mechanism be detached from top pressure face.
Beneficial effect：During due to installation, box spanner can move ahead with the screw-in of bolt, by sleeve barrel spanner
Top pressure face is set on hand, and after bolt screws in the depth dimensions of setting, top pressure face can be pressed against on the surface of setting, to limit
It has made box spanner to continue to move ahead, but box spanner still can rotate under the driving effect of driving device, at this point, by
In the externally threaded transmission effect on bolt, bolt will continue to move ahead until bolt completely disengaged with grafting drive mechanism, disengaging
Bolt afterwards can stop operating to realize the installation of bolt.The rotation of bolt can be limited by using box spanner of the invention
Enter size, facilitate to the Fast Installation for depositing stackware, and during bolt is installed, also avoids bolt and be screwed onto root meeting
The case where driving hand-held components to be rotated, ensure that installation when operation, improve deposit the assembly efficiency of stackware with
And the assembly precision of bolt, save corresponding assembly cost.
Further, box spanner includes that rear side is provided with the wrench body of the grafting drive mechanism and is sleeved on
The rear end face of the top-pressure part of the wrench body peripheral side, the top-pressure part constitutes the top pressure face, and the top-pressure part is along preceding
Rear direction position is adjustable to be assemblied in the wrench body.Top-pressure part position is adjustable to be assemblied in wrench body, so that top
The distance between pressure surface and grafting drive mechanism are adjustable, to realize the adjustable of bolt thread depth, enable bolt root
According to the distance that actual conditions adjustment screws in, the versatility of box spanner is improved.
Further, the top-pressure part is sleeved on the outside of the wrench body by the way of Screw assembly, described to pull
The positioning knot when top-pressure part is adjusted to corresponding position for the top-pressure part to be fixed is additionally provided on hand ontology
Structure.Screw assembly facilitates the position adjustment of top-pressure part, and top-pressure part can be fixed for location structure, avoids installation bolt
When top-pressure part there is a situation where movement.
Further, the location structure is locking nut of the Screw assembly in wrench body peripheral side.Locking screw maternal
Just it operates, is easily installed.
Further, the transmission connecting structure is the first drive hole being arranged on front side of the wrench body.First drives
Dynamic hole is convenient for setting and has stronger structural strength.
Further, the driving device is driving motor, is provided on the inner wall of first drive hole for driving electricity
The inner hole of snap insertion on machine.The setting of inner hole limits the displacement of driving motor along the longitudinal direction, improves the peace of operation
Quan Xing.
Further, the grafting drive mechanism is the second drive hole being arranged on rear side of the wrench body.Second drives
Dynamic hole is convenient for setting and has stronger structural strength.
Further, the rear side of the wrench body is tubular structure, and second drive hole is arranged in the tubulose knot
The inside of structure.Tubular structure have protective effect, avoid the second drive hole setting it is shallower, during installation bolt be easy
The case where causing safety accident is detached from from the second drive hole.
