Description
Technical field
The present invention relates to power supply lines to build technical field.
Background technique
Aerial earth wire is the important component of high voltage transmission line line structure.High pressure and EHV Substation occupied area
Extensively, it is desirable that the region of direct striking thunder prevention is big, and installation lightning rod can have any problem, thus also be protected sometimes using aerial earth wire, makes somebody a mere figurehead ground
Line is erected above protected conducting wire.Aerial earth wire is the important component of high voltage transmission line line structure, due to defeated
Electric line will cross over wide region, be subject to lightning stroke in thunderstorm season and power transmission is caused to be interrupted, become generation power outage
One of the main reason for.Aerial earth wire is all the top for being erected at high-voltage transmission line pole tower, in thunderstorm weather, lightning channel
It is easy to hit aerial earth wire first, lightning current is made to enter the earth, to protect the normal power transmission of conducting wire, therefore, installation aerial earth wire can
To reduce lightening hazard, the safety of route operation is improved.Important transmission line of electricity uses two aerial earth wires generally with will be by
The conducting wire of protection is all placed in its protection scope.This range is usually indicated with shielding angle α.The angle α refer to aerial earth wire with
Plane locating for outermost conducting wire and aerial earth wire are perpendicular to the angle constituted between the plane on ground.Generally take α≤
20 ° -30 ° are thought that conducting wire can be protected, and therefore, be there are certain requirements to the height of aerial earth wire, can just be played guarantor
Shield effect.
It is existing when setting up aerial earth wire or maintenance to mention line apparatus more complex, it is inconvenient to use, routine maintenance tool compared with
Weight, upper and lower transfer tape carry out very big inconvenience, and antenna height and angle need first to measure after it is set up again, this just makes
At setting up, error is larger.
In the operating maintenance work of transmission line of electricity, need that the height of aerial earth wire is checked and adjusted, by ground wire
After the adjustment data record of height, as foundation, provided conveniently for the adjustment period of subsequently aerial earth wire.Specifically, a people
On climbing to wire pole tower, manual operation lifting device is by ground wire lifting or decline, and another manpower takes scale, by scale
The label risen or fallen is made, the numerical value risen or fallen is recorded, the angle α is then measured, in this way, the hand of survey crew needs
A position is remained at, the value that rises or falls of aerial earth wire could be accurately measured, inconvenient to use, operation is more complex,
And need staff more.
Summary of the invention
The technical problem to be solved by the present invention is in view of the above shortcomings of the prior art, provide a kind of aerial earth wire mention line and
Apparatus for examination and repair, be both able to satisfy set up aerial earth wire when propose line requirement, while also be able to satisfy measurement aerial earth wire and power transmission line it
Between distance and angle requirement, it is widely used, it is easy to operate, it is time saving and energy saving, save human resources, securely and reliably.
In order to solve the above technical problems, the technical solution used in the present invention is: it is characterized by comprising pedestal, mentioning line
Plate and measuring device for measuring distance and angle between aerial earth wire and power transmission line；The chassis side is equipped with and is used for and bar
The fixation device that tower is connected, pedestal have the traveling wheel matched with power transmission line；The line plate that mentions is set on the base portion,
Lifting device one end is fixed on the base, described to mention line plate and the removable connection of the lifting device；The line plate that mentions is equipped with
Two can be arranged along the hook for proposing the left and right sliding of line plate, two hooks in lifting device the same side；The line plate that mentions is equipped with
The top both ends of the pedestal can be set along the measuring device for proposing the left and right sliding of line plate, the measuring device, and be located at institute
The rear side for mentioning line plate is stated,；The measuring device includes setting graduated measuring scale and connecting plate, and measuring scale is arranged in connecting plate
On, connecting plate is slided on mentioning line plate by sliding block, and measuring scale can go up and down and rotate on connecting plate.
The beneficial effects of adopting the technical scheme are that the present invention is easy to use, aerial earth wire can be mentioned
Rise, but be able to satisfy measurement aerial earth wire and power transmission line between distance and the demand of angle, moreover it is possible to meet among aerial earth wire certain
When something goes wrong, the maintenance to aerial earth wire is widely used, and easy to operate, securely and reliably, a people can be completed, time saving for section
It is laborsaving, working efficiency is improved, manpower, save the cost are saved.
The present invention is fixed on shaft tower when mentioning line, measurement distance or angle by that will fix device, and the present invention is solid
It is fixed, the distance between aerial earth wire and power transmission line are changed by lifting device；Aerial earth wire and transmission of electricity are measured by measuring device
Vertical range and oblique line distance between line, and then the folder between aerial earth wire and power transmission line is calculated using trigonometric function relationship
Angle；The angle between aerial earth wire and power transmission line is directly either read using angle dial by rotation measuring ruler；Measurement
Ruler is equipped with indicator light and plays suggesting effect, first pre- when staff is at a distance from adjusting aerial earth wire is between power transmission line
The length for first setting measuring scale will mention line plate and move down, and light when indicator light switch touches power transmission line warning light, explanation
Notice board reaches predetermined position, and the distance between aerial earth wire and power transmission line meet demand will not excessively cause defeated because of adjusting
Wire bend impacts the distance between aerial earth wire and power transmission line, improves degree of regulation.
Among maintenance when certain section of aerial earth wire, traveling wheel is placed on power transmission line, and locks traveling wheel, staff
It is sitting in the present apparatus, the mobile present apparatus, overhauls aerial earth wire on power transmission line.
