Description
Technical field
The present invention relates to terminal tower cable fixture technical field, more particularly, to a kind of conducting wire fixed platform stent.
Background technology
Cable termination tower is used widely in city power transmission and transformation field, is mainly used for aerial condutor transmission of electricity being converted into
Cable power transmission.Current terminal tower common on the market there are one it is larger the shortcomings that：Not for fixing the flat of conducting wire on tower body
Platform, can cause in this way conducting wire guided to from above under when, more violent swing is easily generated by wind effect, causes conducting wire
The place connection that lower part is connect with arrester is unstable, so as to be highly susceptible to fatigue rupture over time.
In order to solve the above problem existing for conventional terminal tower, also occur being designed with fixed conducting wire platform branch on the market
Frame, through operating experience for many years and Force Calculation, fixed conducting wire platform support installation site is the arrester of cable termination tower platform
And it is more suitable at about 3~5 meters of end top, if apart from excessive, it may be to reducing wind function and effect unobvious；If away from
From too small, construction when, would become hard to carry out the crooked radian of conducting wire between fixed conducting wire platform support and arrester, and increase is applied
Work difficulty.But another shortcoming is produced again while fixed conducting wire platform support is increased：Utilize conducting wire stage+module
Excessive with the difficulty of maintenance supporting insulator, work is inconvenience, and safety is poor.Due to the supporting insulator of usual 110kV
It is about 1.5 meters, even about 2.0 meters of 220kV so that the place of installation and maintenance supporting insulator and outside fixation conducting wire seems
It is very not convenient.Usually there was only two methods：One is hanging root rope fixed personnel by the undermost conducting wire cross-arm of steel tower, pacified
Dress and maintenance, are equivalent to and personnel are suspended in mid air, and such method safety risk is big, and in power construction, safety supervision department is mostly not
Agree to such method；Secondly first to fix supporting insulator outboard wire, after supporting insulator is mounted on fixed conducting wire again
On platform support, during such mode construction and installation, since supporting insulator is heavier, installation personnel task difficulty is big, and such side
Method is not used to later stage maintenance, can not particularly check the quality state of supporting insulator and fixed conducting wire connection status.

Securely and reliably.
In addition, the bracket institution 200 further includes oblique connecting rod 500, the oblique connecting rod 500 is equipped with institute
Location locking mechanism 400 is stated, first auxiliary supports 340 and second auxiliary supports 360 pass through the positioning
Retaining mechanism 400 is fixed with the oblique connecting rod 500.The oblique connecting rod 500 is set to the middle part of rectangular frame
Hollow part, when above-mentioned auxiliary supports 320, which stretch out bracket component, is in use state, additionally it is possible to ensure to extend away from the one of end
End is fixed on by screw rod on oblique connecting rod 500, it is ensured that staff stands will not cause Auxiliary support in projecting end
The overturning of part 320 avoids endangering the personal safety of staff.
Further, above-mentioned conducting wire fixed platform stent further includes protection mechanism 700, and the protection mechanism 700 is rotatably solid
Due to the auxiliary support apparatus 300.Protection mechanism 700 includes connecting by axis pin, rotates and be fixed on branch in the present embodiment
Plate in frame structure, when auxiliary support apparatus 300 is in use state, staff can manually set plate turning vertical
It is placed on supporting structure, and mutually splicing is fixed forms annular shield mechanism 700, when work can play staff protection
Effect avoids the harm that high-altitude is dropped from occurring, it is ensured that the personal safety of staff.
Such as Fig. 4, shown in Fig. 5, in addition, first sliding rail 352 and second sliding rail 354 include sliding rail connector
370 and the sliding track body 372 that is connect with the sliding rail connector 370, the sliding track body 372 is equipped with sliding slot 374, and described the
One auxiliary supports 340 and second auxiliary supports 360 include clamping portion 376, the clamping portion 376 and the sliding slot
374 cooperation snappings.The sliding track body 372 is clod wash inner bead channel steel in the present embodiment, with semi-enclosed cunning
Slot 374, the clamping portion 376 are the channel steel that section is U-shaped, and the shape of the channel steel and the sliding slot 374 matches, Ke Yiti
Thus the compactedness of high assembling structure ensures that first auxiliary supports 340 or second auxiliary supports 360 are moving
Stability when dynamic avoids generating and collides or shake, influences service life.
Above-mentioned conducting wire fixed platform stent further includes haulage gear in the present embodiment, and the haulage gear includes being set to
Pedestal on the oblique connecting rod 500, is connect the rotating member that is rotatably fixed on the pedestal with the rotating member
Handle and around loaded on the traction piece on the rotating member, one end of the traction piece is fixed with the rotating member, the traction piece
The other end fixed with first auxiliary supports 340 or second auxiliary supports 360.The haulage gear is preferably
Hand wheel component, wheel seat are fixed on oblique connecting rod 500, and guide wheel is rotatably dispose on wheel seat, and one end and the guide wheel of cable are consolidated
Fixed, the other end is connect with the end of first auxiliary supports 340 or second auxiliary supports 360, when needing to move
It during above-mentioned auxiliary supports 320, can be realized by shaking handwheel, and time saving and energy saving, easy to operate, reliable operation.In addition,
Preferred working condition is arranged in parallel for the section of stretching out of auxiliary supports 320 with insulated support and length is identical (concordant), is
Reach above-mentioned purpose, label can be made on cable or on auxiliary supports 320, worker personnel are sentenced by observing label
The disconnected number of turns for shaking handwheel, it is possible to the more accurate length realized control auxiliary supports 320 and stretched out, it is not only easy to operate,
It is and intuitive and reliable.
Further, the connection of the traction piece and first auxiliary supports 340 or second auxiliary supports 360
It holds as away from one end of direction of travel.When cable is fixed on end of travel, when pulling cable, point lifted upwards can be generated
Power can generate the influence for being unfavorable for pulling auxiliary supports 320 so that operation is more laborious, and efficiency is low.And cable is fixed on
Away from one end of direction of travel, property that can realize makes auxiliary supports 320 realize mobile power is thrust rather than pulling force,
So that it is guaranteed that the power that cable is acted on auxiliary supports 320 is completely used for drawing, the efficiency of operation is improved.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, it is all considered to be the range of this specification record.
Embodiment described above only expresses the several embodiments of the present invention, and description is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that those of ordinary skill in the art are come
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
