Abstract
The invention discloses a wire tensioner for pylon line maintenance. The wire tensioner for pylon line maintenance comprises an upper tension plate A and an upper tension plate B. The upper tension plate A is a rectangular plate. Two posts axially parallel are arranged at one end of the upper tension plate B. The upper tension plate A is inserted between the two posts. A rotating shaft penetrates the upper tension plate A and the posts so that the upper tension plate A and the upper tension plate B form a clamp structure. A pull rope A is connected to one end, between the two posts, of the upper tension plate A; a pull rope B is connected to one end, far away from the posts, of the upper tension plate B; with the rotating shaft as the boundary, a lower clamp arc plate is disposed on one side, facing the upper tension plate B, of the upper tension plate between the rotating shaft and the pull rope B, an upper clamp arc plate is disposed on side, facing the upper tension plate A, of the upper tension plate B between the rotating shaft and the pull rope B, and the lower clamp arc plate and the upper clamp arc plate form a clamping structure for clamping a cable. The wire tensioner for pylon line maintenance has the advantages that the structure is simple, operation is simple, safety is high and the cable suffers less damage.
Description
Technical field
The present invention relates to the electric wire tower line maintenance electric wire take-up device in power equipment.
Background technology
In electric power transmission line, electric wire tower is a kind of long-distance transmission device of routine, electric wire tower is to adopt insulation column one end to be connected with electric wire tower with the connected mode of power transmission cable line, the insulation column other end is connected with power transmission cable line, adopt insulation column to articulate power transmission cable line, thereby cable is played to the effect of tension, the area taking place frequently at lightning strike accident, insulation column tends to be struck by lightning and causes damage, now need insulation column to change, conventional mode of operation is: adopt a rope, one end of rope is provided with hook, the other end of rope is connected with electric wire tower, hook directly hangs on high-level cable, after rope is exceptionally straight, can be to insulation column operation, the insulation column more renewing after insulation column is taken off, rope now plays the effect of interim insulation column, there is following shortcoming in existing operating type, hook is little with the contact area of cable, can cause damage to cable, hook easily moves along cable, cause poor safety performance, hook easily comes off.
Summary of the invention
The object of the present invention is to provide a kind of electric wire tower line maintenance electric wire take-up device, improve fail safe, reduce the damage to cable.
Object of the present invention is achieved through the following technical solutions: electric wire tower line maintenance electric wire take-up device, comprise arm-tie A and upper arm-tie B, upper arm-tie A is a rectangular slab, a side of upper arm-tie B is provided with 2 axis parallel columns, upper arm-tie A inserts between 2 cylinders, rotating shaft runs through arm-tie A and 2 cylinders make arm-tie A and upper arm-tie B form clamp structure, upper arm-tie A one end between 2 cylinders is connected with stay cord A, upper arm-tie B is connected with stay cord B away from one end of cylinder, taking rotating shaft as line of demarcation, upper arm-tie A between rotating shaft and stay cord B is provided with lower folder arc towards a side of upper arm-tie B, upper arm-tie B between rotating shaft and stay cord B is provided with upper folder arc towards a side of upper arm-tie A, lower folder arc and upper folder arc form the clamp structure of clamping cable.
The design principle of said structure is: by stay cord B and stay cord A exceptionally straight after, under the pulling force effect of stay cord B and stay cord A, under lever principle, upper arm-tie A between rotating shaft and stay cord B exerts pressure downwards, upper arm-tie B between rotating shaft and stay cord B upwards exerts pressure, thereby makes lower folder arc and upper folder arc can clamp cable.Cable be subject to lower folder arc and on press from both sides after the clamping of arc, the contact-making surface of cable and clamp structure increases greatly, damage situations minimum when can ensureing that cable is held.In addition, due to the structure that the clamp structure of lower folder arc and the formation of upper folder arc is encircling type, be therefore difficult for making said structure to depart from cable, improved greatly security performance.Adopt two stay cords, stay cord B and stay cord A, can increase coefficient of safety simultaneously.
Preferably.Lower folder arc is provided with protrusion tooth with the relative face of upper folder arc.Arrange and protrude tooth to increase the interlock effect of clamp structure.
Preferably, stay cord A and stay cord B are connected on the electric wire tower that is positioned at cable top.
Preferably, the length range of lower folder arc and upper folder arc is at 0.2 meter to 0.5 meter.
The invention has the advantages that: simple in structure, simple to operate, security performance is high, cable is impaired little.

Reference numeral in figure is expressed as: 1, stay cord A; 2, upper arm-tie A; 3, upper arm-tie B; 4, rotating shaft; 5, upper folder arc; 6, lower folder arc; 7, stay cord B; 8, cable; 9, protrude tooth.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
Embodiment 1:
As shown in Figure 1-Figure 3.
Electric wire tower line maintenance electric wire take-up device, comprise arm-tie A2 and upper arm-tie B3, upper arm-tie A2 is a rectangular slab, a side of upper arm-tie B3 is provided with 2 axis parallel columns, upper arm-tie A2 inserts between 2 cylinders, rotating shaft 4 runs through arm-tie A2 and 2 cylinders make arm-tie A2 and upper arm-tie B3 form clamp structure, upper arm-tie A2 one end between 2 cylinders is connected with stay cord A1, upper arm-tie B3 is connected with stay cord B7 away from one end of cylinder, taking rotating shaft 4 as line of demarcation, upper arm-tie A2 between rotating shaft 4 and stay cord B7 is provided with lower folder arc 6 towards a side of upper arm-tie B3, upper arm-tie B3 between rotating shaft 4 and stay cord B7 is provided with upper folder arc 5 towards a side of upper arm-tie A2, lower folder arc 6 and upper folder arc 5 form the clamp structure of clamping cable 8.
The design principle of said structure is: by stay cord B7 and stay cord A exceptionally straight after, under the pulling force effect of stay cord B7 and stay cord A, under lever principle, upper arm-tie A2 between rotating shaft 4 and stay cord B7 exerts pressure downwards, upper arm-tie B3 between rotating shaft 4 and stay cord B7 upwards exerts pressure, thereby makes lower folder arc 6 and upper folder arc 5 can clamp cable 8.Cable 8 be subject to lower folder arc 6 and on press from both sides after the clamping of arc 5, the contact-making surface of cable and clamp structure increases greatly, damage situations minimum when can ensureing that cable is held.In addition, the structure that the clamp structure forming due to lower folder arc 6 and upper folder arc 5 is encircling type, is therefore difficult for making said structure to depart from cable, has improved greatly security performance.Adopt two stay cords, stay cord B7 and stay cord A, can increase coefficient of safety simultaneously.
