Description
Technical field
The utility model relates to transmission line and changes conductor spacer specific purpose tool, is specially one ± 660kV DC power transmission line and changes conductor spacer specific purpose tool.
Background technology
Because the size of ± 660kV DC power transmission line conductor spacer and every structure have certain uniqueness, the specific purpose tool therefore changing conductor spacer also there are differences, and original 500kV changes conductor spacer specific purpose tool cannot be applicable to ± 660kV DC power transmission line.Therefore, be badly in need of developing one and be applicable to ± 660kV DC power transmission line changes conductor spacer specific purpose tool, this instrument should possess simultaneously be convenient for carrying, be easy to use, material is sturdy and durable, anti-corrosion, the feature such as anti-skidding.
Summary of the invention
The utility model solves existing replacing conductor spacer specific purpose tool and cannot be applicable to ± problem of 660kV DC power transmission line, and provide one ± 660kV DC power transmission line to change conductor spacer specific purpose tool.
The utility model adopts following technical scheme to realize: ± 660kV DC power transmission line changes conductor spacer specific purpose tool, comprises cylindrical alloy steel drum post; One end of cylindrical alloy steel drum post is hinged with free bearing by bearing pin, and non-hinge end (free end) of free bearing has hole, is inserted with the strip torque arm of two ends with plug in hole; The other end of cylindrical alloy steel drum post is provided with column adjusting head, and one end of column adjusting head is threaded with the other end of cylindrical alloy steel drum post, and the other end of column adjusting head is hinged with tongue sheet by bearing pin.Strip torque arm to be connected with cylindrical alloy steel drum post by free bearing and bearing pin and to reach collapsible effect, column adjusting head is threaded with cylindrical alloy steel drum intercolumniation, the adjustment (tongue sheet also can rotate arbitrarily around its bearing pin) at the flexible of column adjusting head and tongue position can be realized, thus make this specific purpose tool be adapted to the ± replacing of 660kV DC power transmission line conductor spacer, improve operating efficiency.
The utility model provides one and is applicable to ± 660kV DC power transmission line replacing conductor spacer specific purpose tool, solve the easy-to-rust that existing instrument exists, material bending resistance degree is poor, carry inconvenience, operating efficiency is low, torque arm easily skids, in operation, easily there is instrument obscission, when carrying out replacing DC power transmission line conductor spacer, shaft and tongue position such as to have some limitations at the problem.Its reasonable in design, novelty, be a kind ofly desirable to be applicable to ± 660kV DC power transmission line changes conductor spacer specific purpose tool.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-cylindrical alloy steel drum post, 2-free bearing, 3-strip torque arm, 4-column adjusting head, 5-tongue sheet.
Embodiment
± 660kV DC power transmission line changes conductor spacer specific purpose tool, comprises cylindrical alloy steel drum post 1; One end of cylindrical alloy steel drum post is hinged with free bearing 2 by bearing pin, and non-hinge end (free end) of free bearing 2 has hole, is inserted with the strip torque arm 3 of two ends with plug in hole; The other end of cylindrical alloy steel drum post 1 is provided with column adjusting head 4, and one end of column adjusting head 4 is threaded with the other end of cylindrical alloy steel drum post 1, and the other end of column adjusting head 4 is hinged with tongue sheet 5 by bearing pin.During concrete enforcement, the diameter of column adjusting head 4 is identical with the diameter of cylindrical alloy steel drum post 1, and one end of column adjusting head 4 be external screw thread, the other end of cylindrical alloy steel drum post 1 is screw, realizes being threaded between the two with this.The other end of column adjusting head 4 is provided with open slot, described tongue sheet 5 is positioned at open slot, bearing pin realizes the hinge of tongue sheet 5 and the column adjusting head other end through open slot and tongue sheet 5, like this, tongue sheet 5 can rotate more flexibly in open slot, makes more reasonable structure, specification.The non-hinge end of free bearing 2 for hemispherical, make structure and shape more reasonable.The surface of cylindrical alloy steel drum post 1 and strip torque arm 3 is provided with annular knurl, not easily skids in using.This specific purpose tool is identical with the using method of existing similar tools.
