Description
Technical field
The utility model belongs to the transmission line construction equipment technical field, is specifically related to a kind of transmission line overhead ground wire lifter.
Background technology
Transmission line: be to connect the 35kV between power plant and transformer station and the transformer station and the power circuit of above electric pressure.Overhead ground wire (claiming lightning conducter again): be the top that is arranged at transmission pressure, be used to prevent that lead is subjected to direct stroke.Important transmission line is usually with two overhead ground wires.
Along with increasing of projects such as railway transformation, afforestation, urban planning, transmission line often need set up shaft tower again or increase shaft tower, simultaneously, in the time of newly-built transmission overhead line, be for the main difficult point of the installation of overhead ground wire in the lifting work of ground wire, because the cat head cross-arm is less can not to carry out every work easily, need the instrument of a kind of convenience, specialty to carry out this work.
Summary of the invention
The purpose of this utility model is to provide a kind of transmission line overhead ground wire lifter simple in structure.
To achieve these goals, technical solution adopted in the utility model is: transmission line overhead ground wire lifter, it is characterized in that it comprises jig, anchor clamps, first clamp nut, second clamp nut, screw mandrel, lifting nut, handle, jig is provided with U type groove, the notch of U type groove down, jig is provided with first hole, second hole, U type groove is between first hole and second hole, anchor clamps become the U type, the both ends of anchor clamps are provided with external screw thread respectively, one end of anchor clamps screws on first clamp nut after passing first hole from bottom to top, and the other end of anchor clamps screws on second clamp nut after passing second hole from bottom to top; One end of jig is provided with lift span, and the bottom of screw mandrel is provided with hook, and the upper end of screw mandrel screws on lifting nut after passing lift span from bottom to top, and an end and the lifting nut of handle are hinged.
The beneficial effects of the utility model are: adopt said structure, it is simple in structure.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1-jig, 2-U type groove, 3-anchor clamps, 4-first clamp nut, 5-second clamp nut, 6-screw mandrel, 7-hook, 8-lifting nut, 9-handle.
Embodiment
As shown in Figure 1, transmission line overhead ground wire lifter, it comprises jig 1, anchor clamps 2, first clamp nut 4, second clamp nut 5, screw mandrel 6, lifting nut 8, handle 9, jig 1 is provided with U type groove 2, the notch of U type groove 2 down, jig 1 is provided with first hole, second hole, U type groove 2 is between first hole and second hole, 2 one-tenth U types of anchor clamps, the both ends of anchor clamps 2 are provided with external screw thread respectively, one end of anchor clamps 2 screws on first clamp nut 4 after passing first hole from bottom to top, and the other end of anchor clamps 2 screws on second clamp nut 5 after passing second hole from bottom to top; One end of jig 1 is provided with lift span, and the bottom of screw mandrel 6 is provided with hook 7, and the upper end of screw mandrel 6 screws on lifting nut 8 (formation screw pair) after passing lift span from bottom to top, and an end and the lifting nut 8 of handle 9 are hinged.
Carry out the operation that ground wire is installed:
1, jig is stuck in (cross-arm is between jig 1 and U type anchor clamps 3) on the ground wire cross-arm, and fastening first clamp nut 4, second clamp nut 5;
2, rotary handle 9, and the length of adjusting screw mandrel 6 makes hook 7 hook overhead ground wire;
3, turning handle, screw mandrel rises, and promotes overhead ground wire (claiming lightning conducter again).
This transmission line overhead ground wire lifter uses simple, can finish the lifting work of ground wire very like a cork.
