Description
Technical field
It the utility model is related to a kind of manual tool of electric power apparatus examination, and in particular to a kind of labour-saving spanner.
Background technology
The continuous development of economic society causes electricity needs to continue to increase, and power equipment scale also constantly increases.In addition,
Urban planning and build, especially urban central zone, it is contemplated that urban and reduce security risk, distribution builds cable
Equipment is increasingly becoming new trend on substitution overhead line, station equipment substitution column.Repair based on condition of component can exclude power equipment in advance
The defects of add up in operation or running environment badly causes, so that it is accident to avoid development of defects, improve the operation of distribution
Reliability and security.In repair based on condition of component and incident processing procedure, inevitably need under damage or insulation performance
Drop can not meet that the casing, contact box, switch card of service requirement are replaced, when replacement need to remove in switchgear busbar with
The equipment such as contact, and generally use screw connection between busbar and at cable joining seam, it is therefore desirable to a kind of instrument, in maintenance,
The nut of the equipment rooms such as busbar and contact is removed from bolt.At present, the spanner of electric power apparatus examination in the prior art,
Two spanners need to be used when dismounting or connection, be respectively acting on screw bolt and nut：One spanner is used for fixing bolt, another spanner
It is main to exert oneself, so as to prevent both relatively rotate from achieving the purpose that disassembly and assembly, yet with the switchgear of power equipment
Narrow space, especially close to busbar room bottom and turns over corner on the inside of line cabinet, is limited by space and be not easy to operate, caused
Time-consuming and laborious using conventional spanner in maintenance process, maintenance process takes longer, and power off time is longer.
Utility model content
For the deficiency in the presence of the prior art, the utility model provides a kind of labour-saving spanner, can solve tradition
Work pattern both hands in narrow space use the inconvenient problem of two spanners, lifting switching station, power distribution room repair based on condition of component and thing
Therefore treatment effeciency, alleviate the labor intensity in operation process, shorten power off time.
To achieve the above object, the utility model employs following technical solution：
A kind of labour-saving spanner, including splined shaft and sleeve, upper cartridge are equipped with the bolt head groove of opening upwards, and lower part is set
There is the cylindrical groove that Open Side Down, splined shaft both ends are respectively sleeved on the first attachment device and the second attachment device, the first connection
Device can be moved up and down along the axis of splined shaft, and the second attachment device is fixedly connected with splined shaft；Sleeve is arranged on the first connection
Between device and the second attachment device；The one end of first attachment device away from splined shaft is provided with nut shape sets of holes, the second connection
The one end of device away from splined shaft is provided with cylindrical body；Reverse box is additionally provided between sleeve and the second attachment device；It is described
Reverse box includes babinet, and intermeshing gear wheel and pinion gear are equipped with babinet, is led in gear wheel along axis equipped with cylindricality
Hole, the cylindrical body in the second attachment device are installed in the cylindricality through hole in gear wheel；Top is equipped with along axis in the middle part of pinion gear
Cylindrical projection, cylindrical projection are installed in the cylindrical groove of sleeve.
Nut on bolt to be torn open is placed on the nut shape set of first attachment device one end by the utility model when in use
In hole, bolt head to be torn open is placed in the bolt head groove in sleeve, when rotating splined shaft, in the first attachment device
Nut shape sets of holes drive nut to be torn open to rotate, and direction of rotation is identical with splined shaft direction of rotation, and consolidate with the second attachment device
Surely the gear wheel in reverse box connected is rotated with the rotation of splined shaft, and direction of rotation and splined shaft direction of rotation
It is identical, but direction of rotation of the direction of rotation of the pinion gear engaged with gear wheel then with splined shaft connects on the contrary, being fixed with pinion gear
The direction of rotation of the sleeve connect also the direction of rotation with splined shaft on the contrary, the rotation of the bolt head for the bolt to be torn open placed in sleeve
Turn direction also with splined shaft direction of rotation on the contrary, therefore bolts and nuts to be torn open realize reverse rotation under the rotation of splined shaft,
And then realize the disassembly and assembly of bolts and nuts.Relative to the prior art, the utility model to a direction by rotating
Spanner, so as to fulfill bolt and screw rod direction of rotation on the contrary, realizing disassembly and assembly, for the same screw of disassembly and assembly,
Compared to traditional work pattern, time-consuming 50% can be shortened using the spanner operation, and by the reverse box on spanner, this is pulled
Hand only needs one hand to complete to operate, and the work for narrow space can save a large amount of activity durations.
Compared with the prior art, the utility model by existing both hands single load bearing work pattern be improved to it is singlehanded it is two-way by
Force mode, can lift O＆M overhaul efficiency, alleviate operation labor intensity, shorten the maintenance power off time of power equipment.
