The utility model relates to a kind of goaf strain insulator overhead ground wire adjusting device, and supporting seat is fixed on base upper surface, and rotating disk bottom centre is provided with mandrel, and have the hole of installing mandrel in the middle part of supporting seat, rotating disk is installed in supporting seat by mandrel; Rotating disk top is provided with U-shaped support slot, U-shaped support slot two ends cell wall has screw mandrel installing hole symmetrically, screw to be loaded in screw supporting seat and to coordinate with screw supporting seat medial gap, and screw mandrel is arranged in screw mandrel installing hole and screw screwed hole, and screw mandrel front end is provided with connection overhead ground wire.Base is connected with inclination cross arm of tower, the ground wire crimping pipe ring link vacant lot line of screw mandrel front end, after shaft tower tilts, staff only need rotate screw makes screw mandrel stretch, i.e. adjustable articulator vacant lot line length, rotating disk can with the angular turn of overhead ground wire, thus make the out-of-balance force of pole tower ground wire be discharged flexibly, easily.
Description
Technical field
The utility model relates to goaf transmission line, particularly a kind of goaf power line tension overhead ground wire adjusting device.
Background technology
There is imbalance due to shaft tower inclination or displacement in the power line tension overhead ground wire tension force being positioned at goaf, tower head flexural deformation line-outage contingency may occur time serious.At present, can only step on tower regulate by operating personnel, by the out-of-balance force adjustment release of stressed ground wire side, operation process labour intensity is large, and there is potential safety hazard.
Summary of the invention
The technical problems to be solved in the utility model be to provide a kind of can safely, the goaf strain insulator overhead ground wire adjusting device of adjustment release inclination pole tower ground wire out-of-balance force easily.
For solving above technical problem, the technical solution adopted in the utility model is:
A kind of goaf strain insulator overhead ground wire adjusting device, comprise base, supporting seat, rotating disk and screw mandrel screw mechanism, supporting seat is fixed on base upper surface, and rotating disk bottom centre is provided with mandrel, have the hole of installing mandrel in the middle part of supporting seat, rotating disk is installed in supporting seat by mandrel; Rotating disk top is provided with U-shaped support slot, and U-shaped support slot two ends cell wall has screw mandrel installing hole symmetrically, and screw to be loaded in screw supporting seat and to coordinate with screw supporting seat medial gap, and screw mandrel is arranged in screw mandrel installing hole and screw screwed hole.
Base is connected with inclination cross arm of tower with fixed forms such as fixation clamps by bolt, screw mandrel front end is by ground wire crimping pipe ring link vacant lot line, after shaft tower tilts, staff only need rotate screw makes screw mandrel stretch, i.e. adjustable articulator vacant lot line length, rotating disk freely can rotate with the angle change of overhead ground wire, thus the out-of-balance force of pole tower ground wire is discharged.
Adopt goaf described in the utility model strain insulator overhead ground wire adjusting device, can flexibly, adjusting bracket vacant lot line length easily, release ground wire out-of-balance force, this apparatus structure is simple, and installation cost is low, installs and simple to operation, labor strength is low, job safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model goaf strain insulator overhead ground wire adjusting device.
Fig. 2 is the vertical view of Fig. 1.
In figure, 1-base, 2-supporting seat, 3-rotating disk, 4-mandrel, 5-screw, 6-screw mandrel, 7-ground wire crimping pipe ring, 8-cross-arm.
Embodiment
In order to make those skilled in the art better understand the utility model, below in conjunction with accompanying drawing, explanation clear, complete is further done to the utility model.
As shown in Figure 1, 2, base 1, for being connected with cross arm of tower 8, base 1 has screw, during connection, uses bolt and fixation clamp to be fixed on cross arm of tower 8.
As shown in Figure 1, supporting seat 2 is fixed on base 1 upper surface, for installing rotating disk 3.Rotating disk 3 bottom centre is provided with mandrel 4, the hole of installing mandrel 4 is had in the middle part of supporting seat 2, rotating disk 3 is installed in supporting seat 2 by mandrel 4, when there is deviation angle between ground wire and the utility model device, rotating disk 3 can automatically turn over certain angle and make screw mandrel and ground wire point-blank under the skew effect of stress of ground wire.
As shown in Figure 1, 2, rotating disk 3 top is provided with U-shaped support slot, U-shaped support slot two ends cell wall has screw mandrel installing hole symmetrically, screw 5 to be loaded in U-shaped support slot and to coordinate with U-shaped support slot medial gap, screw mandrel 6 is arranged in screw mandrel installing hole and screw 5 screwed hole, staff rotates screw and adjustable ground line length with spanner, release out-of-balance force.
As shown in Figure 1, 2, screw mandrel 6 front end connects ground wire crimping pipe ring 7, connects with overhead ground wire connecting tool.The claimed scope of the utility model is not limited to above embodiment; to those skilled in the art; the utility model can have various deformation and change, all in design of the present utility model and any amendment, the improvement done within principle be equal to replacement and all should be included within protection range of the present utility model.
