Abstract
The utility model discloses a tension tower wire end LF-type yoke plate fixing clamp. The fixing clamp is characterized in that the fixing clamp is composed of a V-shaped clamp plate body and hooks, the hooks are symmetrically arranged on the two end heads of the front end portion of the V-shaped clamp plate body, and a connecting hole is arranged at the rear end portion of the V-shaped clamp plate body. The tension tower wire end LF-type yoke plate fixing clamp is simple in structure, low in cost, and convenient in construction. When LF-type (in a concentric square shape) yoke plate insulator chains are replaced during the power failure of a 220 kV line, a yoke plate can be easily, effectively, rapidly and safely fixed, so that the yoke plate bears the force evenly, deformation and damages on the yoke plate are prevented, the insulator chains are rapidly fastened, the work efficiency is greatly improved, and operations are successfully and safely completed.
Description
Technical field
The utility model relates on a kind of 220kV transmission line the setting tool used while changing the strain rod tower insulator, specifically a kind of strain rod tower conductor wire end LF type yoke plate holding clamp.
Background technology
Along with power network development, a collection of compact line, common-tower double-return circuit put into operation in succession.In order to guarantee the transmission line safe and reliable operation, improve power supply reliability, line maintenance more and more highlights its importance, and along with the increase maintenance amount of line length can get more and more.220kV track replacement strain rod tower insulator string is a complexity and important events in operation in operation, double bundle conductor and insulator junction mostly are LF type (Back Word type) yoke plate of double hanging point, when changing bunch of insulator, stressed owing to not allowing in the middle of yoke plate, without effective fixing point, can't utilize the stringing instrument effectively to connect LF type (Back Word type) yoke plate; And while with general jig, yoke plate being fixed, force part is at mid portion, yoke plate intensity can not meet the force request of stringing instrument to yoke plate; If use general operating procedure, construction intensity is large, and instrument is loaded down with trivial details, makes these events in operation not carry out smoothly fast.
Summary of the invention
Stringing instrument and the problem that LF type (Back Word type) yoke plate effectively is connected when the purpose of this utility model is solve to change strain insulator, provide a kind of on the 220kV transmission line, use simple in structure, with low cost, installation is easy, easy construction, safe and reliable strain rod tower conductor wire end LF type yoke plate holding clamp.
In order to reach above purpose, the technical scheme that the utility model adopts is: this strain rod tower conductor wire end LF type yoke plate holding clamp, it is characterized in that: formed by V-arrangement jig plate body and hook, symmetry is fixed with hook on two terminations of V-arrangement jig plate body front end, is provided with connecting hole in the rearward end of V-arrangement jig plate body.
The length of described V-arrangement jig plate body is 360mm, and thickness is 25mm, and the width of hook is 23mm, and two horizontal widths of linking up with between outward flange are 340mm, and the connecting hole aperture is 24mm.
The beneficial effects of the utility model are: simple in structure, with low cost, easy construction, when carrying out 220kV line outage replacing LF type (Back Word type) yoke plate insulator string, can be easy, effectively, fixing yoke plate quickly and safely, make its uniform stressed, damage does not deform, reach the purpose of tightening up fast insulator string, greatly improved operating efficiency, guarantee that operation completes safely smoothly.
The accompanying drawing explanation
Fig. 1 is structure schematic top plan view of the present utility model;
Fig. 2 is that schematic diagram is looked on a structure of the present utility model left side;
In figure: 1, V-arrangement jig plate body; 2, hook; 3, connecting hole.
Embodiment
With reference to accompanying drawing 1, Fig. 2, make the utility model.This strain rod tower conductor wire end LF type yoke plate holding clamp is characterized in that: V-arrangement jig plate body 1 and hook 2, consist of, symmetry is fixed with hook 2 on two terminations of V-arrangement jig plate body 1 front end, is provided with connecting hole 3 in the rearward end of V-arrangement jig plate body 1.
Described V-arrangement jig plate body 1 and hook 2 are made by a monoblock almag.
The length of described V-arrangement jig plate body 1 is 360mm, and thickness is 25mm, and the width of hook 2 is 23mm, and two horizontal widths of linking up with between 2 outward flanges are 340mm, and connecting hole 3 apertures are 24mm.
When using the utility model to change strain insulator string, intensity, the pulling force of V-arrangement jig plate body 1 and hook 2 should meet 15T, make it equally with the stringing instrument can reach the stringing load requirement, two hooks 2 are stuck in to the inboard at LF type yoke plate side of wire was hanging point position, connecting hole 3 is by U-shaped ring or extend the stringing instruments such as the special-purpose pull bars such as ring and double hook and be connected, these stringing instruments are also just like leading screw, jack, all belong to prior art, the stringing instrument is fixed on shaft tower, when the stringing instrument tightens up, can drive V-arrangement jig plate body 1 moves, thereby making to link up with 2 moves with LF type yoke plate, reach the stringing purpose, make finally that strain insulator string is loose to get off, and insulator monolithic or whole string are changed, thereby reduce the activity duration, alleviate operating personnel's labour intensity, guarantee that operation completes safely smoothly.
