Abstract
A kind of strain insulator drainage overlap joint ladder, is related to power transmission lines overhauling technical field of tools, structure are as follows: including shaft tower solid lock adjuster (6), lifting side terraced (7), X-type safety pull wire (8) and manned horizontal ladder (12).The beneficial effects of the present invention are: the defects of the configuration of the present invention is simple, installation and repairing is convenient, and work efficiency is high, and working strength is small, should be in the circular shape naturally drooped after drainage thread installation, non-warping, no hard curved；The pressing plate for draining end connects the elastic appropriateness of bolt, can accomplish that technique is good, reduces maintenance cost.
Description
One, technical field
The present invention relates to power transmission lines overhauling technical field of tools, and in particular to a kind of strain insulator drainage overlap joint ladder.
Two, background technique
With the fast development of economic society, Electricity customers quantity is continuously increased, and power line load increases considerably, and is made
Route at full capacity or excess load in the state of runs, it is easy to appear strain rod tower drainage and parallel groove clamps under this situation
The phenomenon that fever；Meanwhile since drainage portion construction technology is not in place or there are also can when residual defects when line construction construction
The case where outlet drainage thread and parallel groove clamp fever, corona discharge, above situation will ultimately result in power line tension drainage thread
Broken string causes line tripping accident to influence the normal operation of transmission line of electricity；Overlapped that method is operation for traditional drainage thread
Both ends drainage thread is drawn on cross-arm after connection and puts back to below cross-arm by personnel；But due to the limitation of cross-arm operation, not only
The safe distance not being able to satisfy between drainage thread and cross-arm, at the same it is bad by technique, drainage deformation to the later period operation bring compared with
Big hidden danger, therefore in order to ensure the security and stability of transmission line of electricity operation, it is necessary to it is excellent that technique is produced in power transmission network construction period
Drainage thread or the broken string drainage of repairing replacement in time, research and develop a kind of strain insulator drainage overlap joint ladder.
Three, summary of the invention
The present invention provides a kind of strain insulator drainage overlap joint ladder in view of the deficiencies of the prior art, it is characterised in that: solid including shaft tower
Lock adjuster (6), lifting side terraced (7), X-type safety pull wire (8) and manned horizontal ladder (12)；The shaft tower solid lock adjuster (6) its
Structure passes through tune at the top of adjusting screw (4) to be provided with card slot (5) in the middle part of the adjusting screw (4) of shaft tower solid lock adjuster (6)
Section nut (3) is fixed with hook (2), and hook (2) end is additionally provided with link A(1), the bottom end and lifting side of adjusting screw (4)
The bottom of terraced (7) connection, lifting side terraced (7) is connect by nut (9) with the end foot prop (10) of manned horizontal terraced (12), manned cross
Terraced (12) are additionally provided with link B(11), link A(1) and link B(11) interior it is provided with X-type safety pull wire (8).
The strain insulator drainage overlap joint ladder is by two shaft tower solid lock adjusters (6), lifting side terraced (7) and an X-type safety
Bracing wire (8), manned horizontal terraced (12) composition.
Application method of the invention are as follows: hook (2) and card slot (5) of the invention are fixed on cross-arm, by adjusting spiral shell
Strain insulator is drained overlap joint ladder and is adjusted to proper height by female (3), and maintenance personal can reach manned horizontal ladder by lifting side terraced (7)
(12) drainage thread and insulator being repaired on, end to be repaired, maintenance personal climbs by lifting side terraced (7) onto cross-arm,
Remove all achievable maintenance work of strain insulator drainage overlap joint ladder；The voltage class that the present invention is applicable in be exchange 110kV with exchange 35kV.
The beneficial effects of the present invention are:
The present invention breaches traditional cross-arm overlap joint drainage operational method, develops a kind of strain insulator drainage overlap joint ladder and completes to draw
The maintenance of streamline overlaps work, operating personnel can be overlapped along strain insulator ladder be moved to below cross arm of tower reach near drainage thread into
Row high-altitude maintenance operation is drained to cross-arm without dragging, avoids the drainage caused by overlap joint drainage on cross-arm and forms deficiency, draws
The problems such as stream is inadequate to cross-arm safe distance, drainage deforms broken lot, ensure that drainage thread manufacture craft and upkeep operation efficiency, right
Power transmission lines overhauling work has far-reaching influence.The configuration of the present invention is simple, easy for installation, work efficiency is high, and working strength is small,
The length of lifting side ladder can be adjusted according to different cross-arm structures, should not be had in the circular shape naturally drooped after drainage thread installation
There is the defects of hard curved, distortion, deformation；The pressing plate for draining end connects the elastic appropriateness of bolt, can accomplish that technique is good, reduce dimension
Accomplish this.
