Description
Technical field
The present invention relates to power system device, more specifically to having the pre-buried knot of expansion type in a kind of electric system
The electric pole of structure.
Background technology
Electric pole is exactly the bar installed electricity lines as its name suggests.Each rural area-field-road-street is come across, is early stage
One of important infrastructure of China.The various electric poles of early stage are all to start to walk from rod or even be not including voltage class
Too high high-voltage line electric pole.Development due to steel and armored concrete and technical requirement later, both material generations
Most of rod has been replaced, and applicable timber is progressively rare, and just substantially difficulty is shown in rod inside city.But at some
Less flourishing place is put up telephone lines also using rod, is and the load-bearing of telephone wire because rod is light-weight, it is convenient to set up
Small with pulling force, rod can be competent at, if telephone line has change, move bar and be also convenient for.So there is the wooden telephone wire in part now
Bar.
And current electric pole there are it is certain the problem of, due to installation when need preferable fixed effect, so while electric
Line bar exposed part is longer, and center of gravity is higher, so generally requiring one section of pre-buried pipeline section, to reduce whole center of gravity, ensures solid
Determine effect, and pre-buried pipeline section and the fixed relationship on ground then determine fixed reliability and security, although and being at present
It is poured by cement, and the fixing-stable degree between electric pole and soil, still there is the space of promotion.
The content of the invention
In view of this, it is an object of the present invention to provide the electric poles in a kind of electric system with expansion type pre-buried structure.
In order to solve the above-mentioned technical problem, the technical scheme is that：It is pre-buried with expansion type in a kind of electric system
The electric pole of structure, including the body of rod and the undertaking stent being arranged on the body of rod, the undertaking stent is described for fixed cable
Expansion type pre-buried structure is fixed on the body of rod, the expansion type pre-buried structure includes the expander for extending downwardly setting, described swollen
Swollen body includes several expansion pawls, and setting is shunk in the end of the expansion pawl in opposite directions；
The expansion type pre-buried structure includes expansion piece and driving structure, and the expansion piece is arranged under the body of rod
Side, the driving structure and expansion piece linkage are set so that the expansion piece can downwards be transported under the drive of driving structure
It is dynamic, when the expansion piece moves downward, the end of the expansion piece contact to provide with the expansion pawl it is described expand pawl to
Outer expansive force；
The expansion pawl be flexible expansion pawl so that the expansion pawl is by expansive force when, the end of the expansion pawl is along mutual
The direction movement deviated from；
The driving structure is arranged on the body of rod, and the driving structure further includes a handwheel, and the handwheel is arranged at
The outside of the body of rod rotates the handwheel so that the expansion piece to be driven to move downward.
First, expansion type pre-buried structure can be embedded by this electric pole with expansion type pre-buried structure when in use
Soil is then inserted in ground, then by operating driving structure expansion piece is driven to move downwards expansion type pre-buried structure, directly
It is contacted to it with expansion pawl, so original fluffy soil becomes consolidation under the contact of expansion pawl, improves fixed effect.
Further, the outer wall of the expansion pawl is provided with pawl structure, and the protrusion direction of the pawl structure is by described
The end of expansion pawl is set to the body of rod.
By the setting of pawl structure, ensure the expansion more difficult extraction soil of pawl, play a preferable fixed effect, ensure
Expansion pawl can rationally work.
Further, the driving structure includes leading screw unit and gear unit, and the expansion piece is fixed on the silk
Thick stick unit, the leading screw unit are connected to the handwheel by the gear unit；
The gear unit is arranged to bevel gear component, and the bevel gear component includes the first transmission gear and the second biography
Moving gear, first transmission gear and second transmission gear engagement, first transmission gear and handwheel linkage；
The leading screw unit includes turn-screw and threads of lead screw, and the threads of lead screw is arranged inside the body of rod,
The turn-screw be provided with the threads of lead screw cooperation external screw thread so that the turn-screw rotate when in the silk
The movement on vertical direction is done under the guiding role of thick stick screw thread.
By the setting of driving structure, bevel gear component plays the effect of a commutation, and facilitates inside hand wheel rotating
Turn-screw, and during turn-screw rotation, since the engagement effect of threads of lead screw can move downward guarantee fixed effect, improve knot
Structure stability.
Further, the gear unit includes ratchet component, the ratchet component connect the handwheel and
When first transmission gear is so that the handwheel is rotated in a first direction, the gear unit works to drive the expansion piece
It moves downward；When the handwheel is rotated in a second direction, the gear unit does not work.
By the setting of ratchet, while ensureing fixed effect, reliability is improved, after being installed due to electric pole just not
Can arbitrarily dismounting again, so hand wheel structure also will be ineffective, by the setting of ratchet component, after ensureing that installation is complete,
Handwheel cannot then drive expansion pawl action, ensure the safety and stability of structure.
Further, the expansion piece is arranged to truncated cone-shaped convex block, and the top of the truncated cone-shaped convex block is towards the expansion
The end set of pawl.By the setting of truncated cone-shaped convex block, reliability and security ensure that, improve service life, reduce movement
When the frictional force that generates.
The technology of the present invention effect major embodiment is in the following areas：This electric pole with expansion type pre-buried structure can be
Expansion type pre-buried structure is embedded into ground during use, then inserts soil, then expansion type pre-buried structure is driven by operating
Dynamic structure drives expansion piece to move downwards, until it is contacted with expansion pawl, so original fluffy soil connecing in expansion pawl
Touching down becomes consolidation, improves fixed effect.
