Description
Technical field
The present invention relates 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 potential safety hazard, distribution builds cable
Equipment is increasingly becoming new trend on substitution overhead line, station equipment substitution post.Repair based on condition of component can exclude power equipment in advance
The defects of add up in operation or running environment badly causes, it is accident so as to avoid development of defects, improves the operation of distribution
Reliability and security.In repair based on condition of component and incident processing procedure, inevitably need under damage or insulating properties
Drop can not meet that the sleeve pipe, contact box, switch card of service requirement are changed, need during replacing to remove in switch cubicle 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, the purpose of disassembly and assembly is reached so as to prevent both from relatively rotating, yet with the switch cubicle of power equipment
Narrow space, especially close to busbar room bottom and corner on the inside of line cabinet is turned over, is limited by space and is not easy to operate, caused
Wasted time and energy in maintenance process using conventional spanner, maintenance process is time-consuming longer, and power off time is longer.
The content of the invention
For the deficiency in the presence of prior art, the invention provides a kind of labour-saving spanner, can solve traditional work
Pattern both hands in narrow space using the inconvenient problem of two spanners, are lifted at switching station, power distribution room repair based on condition of component and accident
Efficiency is managed, alleviates the labor intensity in operation process, shortens power off time.
To achieve the above object, present invention employs following technical scheme：
A kind of labour-saving spanner, including splined shaft and sleeve, upper cartridge are provided with the bolt head groove of opening upwards, and bottom is set
There is the cylindrical groove that Open Side Down, splined shaft both ends are respectively sleeved on the first attachment means and the second attachment means, the first connection
Device can be moved up and down along the axis of splined shaft, and the second attachment means are fixedly connected with splined shaft；Sleeve is arranged on the first connection
Between device and the second attachment means；The one end of first attachment means 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 means；It is described
Reverse box includes casing, is provided with intermeshing gear wheel in casing and little gear, gear wheel interior edge axis lead to provided with cylindricality
Hole, the cylindrical body in the second attachment means are arranged in the cylindricality through hole in gear wheel；Top is provided with along axis in the middle part of little gear
Cylindrical projection, cylindrical projection are arranged in the cylindrical groove of sleeve.
Nut on bolt to be torn open is placed in the nut shape sets of holes of first attachment means one end by the present invention when in use,
Bolt head to be torn open is placed in the bolt head groove in sleeve, when rotating splined shaft, the nut in the first attachment means
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 fix and connect with the second attachment means
The gear wheel in reverse box connect rotates with the rotation of splined shaft, and direction of rotation and splined shaft direction of rotation phase
Together, but with gear wheel the direction of rotation of the little gear engaged then the direction of rotation with splined shaft on the contrary, being fixedly connected with little gear
Sleeve direction of rotation 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
Direction is entered 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 realize the disassembly and assembly of bolts and nuts.Relative to prior art, the present invention by a direction rotary spanner, from
And bolt and screw rod direction of rotation are realized on the contrary, realizing disassembly and assembly, for the same screw of disassembly and assembly, compared to biography
System work pattern, can shorten time-consuming 50%, and only need list by the reverse box on spanner, the spanner using the spanner operation
Hand can be completed to operate, and the work for narrow space can save a large amount of activity durations.
Compared to prior art, existing both hands single load bearing work pattern is improved to singlehanded bidirectional stress mould by the present invention
Formula, O＆M overhaul efficiency can be lifted, alleviate operation labor intensity, shorten the maintenance power off time of power equipment.
