Description

Transmission line aerial earth wire lifter

Technical field

The utility model belongs to the transmission line construction equipment technical field, is specifically related to a kind of transmission line aerial earth wire lifter.

Background technology

Transmission line: be to connect 35kV between power plant and transformer station and transformer station and the power circuit of above.Overhead ground wire (claiming again lightning conducter): be the top that is arranged at transmission pressure, be used for preventing that wire is subject to direct stroke.Important transmission line is usually with two overhead ground wires.

Along with increasing of the projects such as railway transformation, afforestation, urban planning, transmission line often need again set up shaft tower or increase shaft tower, simultaneously, in the time of newly-built transmission overhead line, installation Major Difficulties for overhead ground wire is in the lifting work of ground wire, can not carry out easily work in every because the tower top cross-arm is less, 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 simple in structure, practical transmission line aerial earth wire lifter.

to achieve these goals, technical solution adopted in the utility model is: transmission line aerial earth wire lifter, it is characterized in that it comprises jig, fixture, the first clamp nut, the second clamp nut, screw mandrel, hook, pullover, handle, bearing, ring body, jig is provided with U-shaped groove, the notch of U-shaped groove down, jig is provided with the first hole, the second hole, U-shaped groove is between the first hole and the second hole, it is U-shaped that fixture becomes, the both ends of fixture are provided with respectively external screw thread, one end of fixture screws on the first clamp nut after passing from bottom to top the first hole, the other end of fixture screws on the second clamp nut after passing from bottom to top the second hole, one end of jig is provided with the elevating screw thread hole, the elevating screw thread hole was revolved in the upper end of screw mandrel, the upper end of screw mandrel is square spigot, be corresponding square opening in pullover, on the pullover square spigot that is enclosed within screw mandrel, pullover hinged with handle, the lower end of screw mandrel is fixedly connected with the outer ring body of bearing by ring body, and the upper end of hook is fixedly connected with the inner ring body of bearing.

The beneficial effects of the utility model are: adopt said structure, it is simple in structure, practical.

Description of drawings

Fig. 1 is structural representation of the present utility model;

In figure: the 1-jig, 2-U type groove, the 3-fixture, 4-the first clamp nut, 5-the second clamp nut, the 6-screw mandrel, the 7-hook, 8-is pullover, 9-handle, 10-bearing, 11-ring body.

Embodiment

as shown in Figure 1, transmission line aerial earth wire lifter, it comprises jig 1, fixture 3, the first clamp nut 4, the second clamp nut 5, screw mandrel 6, hook 7, pullover 8, handle 9, bearing 10, ring body 11, jig 1 is provided with U-shaped groove 2, the notch of U-shaped groove 2 down, jig 1 is provided with the first hole, the second hole, U-shaped groove 2 is between the first hole and the second hole, 3 one-tenth of fixtures are U-shaped, the both ends of fixture 3 are provided with respectively external screw thread, one end of fixture 3 screws on the first clamp nut 4 after passing from bottom to top the first hole, the other end of fixture 3 screws on the second clamp nut 5 after passing from bottom to top the second hole, one end of jig 1 is provided with the elevating screw thread hole, the elevating screw thread hole was revolved in the upper end of screw mandrel 6, and (screw mandrel matches with the elevating screw thread hole, consist of screw pair, rotary screw, but the screw mandrel oscilaltion), the upper end of screw mandrel 6 is square spigot, be corresponding square opening in pullover 8, pullover 8 are enclosed within on the square spigot of screw mandrel 6, pullover 8 with handle 9 hinged (or being fixedly connected with), the lower end of screw mandrel 6 is fixedly connected with the outer ring body of bearing 10 by ring body (circulus) 11, the upper end of hook 7 is fixedly connected with (namely linking up with 7 can not rotate with screw mandrel 6) with the inner ring body of bearing 10.

Carry out the operation that ground wire is installed:

1, jig is stuck in (cross-arm is between jig 1 and U-shaped fixture 3) on the ground wire cross-arm, and fastening the first clamp nut 4, the second clamp nut 5;

2, rotary handle 9, and the height of adjusting screw mandrel 6 makes hook 7 hook overhead ground wire;

3, turning handle, screw mandrel rises, and promotes overhead ground wire (claiming again lightning conducter).

This transmission line aerial earth wire lifter uses simple, can complete very like a cork the lifting work of ground wire.
