Description
Technical field
The invention belongs to power construction technical field of auxiliary equipment, more particularly, to a kind of power circuit frame across river
Line apparatus.
Background technology
Because the quality of transmission pressure particularly high voltage electricity transmission conductive wire in itself is with regard to larger, and for supporting the phase of transmission pressure
Adjacent two steel towers have larger span, while electrical body, crops, trees, river, road between two neighboring steel tower be present
The barrier that road, building and structures etc. are spanned, so, set up or dismounting transmission pressure is a complexity and difficult work
Journey.
In the prior art, set up or dismantle guide rope that power circuit generally use is arranged between two neighboring steel tower and
The coaster for being suspended on guide rope and being controlled by bracing wire, and to avoid power circuit and ground or being spanned barrier with above-mentioned
The crossing frame and insulation net being in contact, the logical framework knot made of steel alloy or the aluminium alloy of lighter weight of crossing frame therein
Structure.Power circuit due to needing to set up or be removed will move under the traction of coaster between two neighboring steel tower,
And it is to be supported by crossing frame and slid thereon during power circuit moves, it can be seen that, crossing frame not only carries
The weight of power circuit, while sliding friction is also produced between power circuit, so, crossing frame is firm also easy in any case
Larger frictional force abrasion caused by the power circuit slid, be particularly removed old power circuit, because of its surface
Have and be similar to zigzag tip, it is easier to make to damage away from more frame；In addition, the frictional resistance between power circuit and crossing frame can also
Considerable influence is produced to traction element, because guide rope and coaster, and bracing wire are acted on by wind-force in the air in height, often gone out
Phenomena such as existing guide rope and guy winding and coaster are offset, coaster movement is more difficult after this phenomenon occurs, and guide rope and drawing
Line is wound and coaster also needs to overcome the frictional resistance between power circuit and crossing frame could be by power line under shift state
Move on road, it is easy to phenomena such as causing power circuit to stagnate, and then the process such as construction progress and increase maintenance capacity is influenceed, it is constructed
Cost significantly improves.A kind of overhead transmission line is disclosed in the Chinese patent of Application No. 201310373308.6 to fill across wiring
Put, including overhead messenger wire, wire barrow, the extension pulley with drive mechanism and vacantly hold in the palm line wheel, the overhead crane line front end leads to
Cross tensioning mechanism to be connected to across on the fixture in front of thing, the extension pulley draws wire to be laid and transported on overhead messenger wire
Dynamic, the hanging support line wheel holds up the wire and is suspended on overhead messenger wire, and the wire barrow leading-out terminal sets wire anti-twist device,
