Abstract
The invention relates to a goaf tension-resistant overhead ground wire adjusting device. A supporting seat is fixed onto the upper surface of a base, a central spindle is arranged at the center of the bottom of a rotary table, a hole for mounting the central spindle is formed at the center of the of the supporting seat, and the rotary table is arranged inside the supporting seat through the central spindle; the top portion of the rotary table is provided with a U-shaped supporting groove, groove walls of two ends of the U-shaped supporting groove are symmetrically provided with screw rod mounting holes, nuts are arranged inside nut supporting seats and are in clearance fit relationship with inside of the nut supporting seats, screws are arranged inside the screw rod mounting holes and nut threaded holes in a penetrating mode, and the front end of the screw rod is provided with a connecting overhead ground wire. The base is connected with a cross arm of a slant tower, the ground wire at the front of the screw rod is connected with a pipe-ring connection overhead ground wire in a pressing mode, when the tower is slanted, a worker only needs to rotate the nuts to enable the screw rods to extend or contract to adjust the length of an overhead ground wire, the rotary table can rotate along with the angle of the overhead ground wire, and accordingly, unbalanced force of a tower ground wire can be released flexibly and conveniently.
Description
Technical field
The present invention relates to goaf transmission line, particularly a kind of goaf power line tension overhead ground wire adjusting device.
Background technology
Because imbalance occurs for shaft tower inclination or displacement, when serious, may there is tower head flexural deformation broken string accident in the power line tension overhead ground wire tension force that is positioned at goaf.At present, can only step on tower by operating personnel and regulate, by the out-of-balance force adjustment release of stressed ground wire side, operation process labour intensity is large, and has potential safety hazard.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of can be 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 used in the present invention 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, supporting seat middle part has the hole that mandrel is installed, and rotating disk is installed in supporting seat by mandrel; Rotating disk top is provided with U-shaped support slot, on the cell wall of U-shaped support slot two ends, has symmetrically screw mandrel installing hole, screw be loaded in screw supporting seat and with screw supporting seat inside matched in clearance, screw mandrel is arranged in screw mandrel installing hole and screw screwed hole.
By bolt, with fixed forms such as fixation clamps, base is connected with inclination cross arm of tower, 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 flexible, it is adjustable articulator vacant lot line length, rotating disk can change with the angle of overhead ground wire and freely rotate, thereby the out-of-balance force of pole tower ground wire is discharged.
Adopt goaf of the present invention strain insulator overhead ground wire adjusting device, can be flexibly, adjusting bracket vacant lot line length easily, discharge ground wire out-of-balance force, this apparatus structure is simple, and installation cost is low, installation and simple to operation, labor strength is low, job safety.
Accompanying drawing explanation
Fig. 1 is the structural representation of goaf of the present invention 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 present invention, below in conjunction with accompanying drawing, the present invention is done to further clear, complete explanation.
As shown in Figure 1, 2, base 1, for being connected with cross arm of tower 8, has screw on base 1, 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 rotating disk 3 is installed.Rotating disk 3 bottom centre are provided with mandrel 4, supporting seat 2 middle parts have the hole that mandrel 4 is installed, rotating disk 3 is installed in supporting seat 2 by mandrel 4, when there is deviation angle between ground wire and apparatus of the present invention, 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 tops are provided with U-shaped support slot, on the cell wall of U-shaped support slot two ends, have symmetrically screw mandrel installing hole, screw 5 be loaded in U-shaped support slot and with U-shaped support slot inside matched in clearance, screw mandrel 6 is arranged in screw mandrel installing hole and screw 5 screwed holes, it is adjustable ground wire length that staff rotates screw with spanner, discharges out-of-balance force.
As shown in Figure 1, 2, screw mandrel 6 front ends connect ground wire crimping pipe ring 7, connect with overhead ground wire connecting tool.The scope of protection of present invention is not limited to above embodiment; to those skilled in the art; the present invention can have various deformation and change, all any modifications of doing within design of the present invention and principle, improves and is equal within replacement all should be included in protection scope of the present invention.
