The five cross arms are horizontally arranged on the post in the vertical direction. The cross arm in each layer is provided with at least two pulley hanging points. Compared with the prior art, the crossing frame has the advantages of safety and reliability.
Description
Technical field
The utility model relates to a kind of power construction auxiliary equipment technical field, especially relates to a kind of safe and reliable crossing frame.
Background technology
Due to transmission pressure, particularly the quality of high voltage electricity transmission conductive wire itself is just larger, and there is larger span for adjacent two steel towers that support transmission pressure, barrier simultaneously that exist electrified body, crops, trees, river, road, building and structures etc. to be crossed between adjacent two steel towers, so, set up or dismantle transmission pressure and be a complexity and difficult engineering.
In prior art, setting up or dismantle transmission pressure conventionally adopts and is arranged on the guide rope between adjacent two steel towers and is suspended on guide rope and by the coaster of bracing wire control, and for avoid transmission pressure and ground or with the above-mentioned crossing frame being contacted by across obstacle and insulation net, crossing frame is wherein led to the frame structure of being made up of the aluminium alloy of steel alloy or lighter weight.Due to needs set up or the transmission pressure that is removed under the traction of coaster, to between adjacent two steel towers, move, and in the process moving at transmission pressure, to be supported and slippage thereon by crossing frame, as can be seen here, crossing frame is not only being carried the weight of transmission pressure, also and between transmission pressure produce sliding friction simultaneously, so, crossing frame is firm in any case is is also easily worn and torn by the larger frictional force that transmission pressure produced of slippage, old transmission pressure is particularly removed, because its surface is similar to zigzag tip, more easily make apart from more frame damage, in addition, frictional resistance between transmission pressure and crossing frame also can produce considerable influence to traction element, because of guide rope and coaster, and bracing wire is subject to the effect of wind-force in the air at height, often there will be the phenomenon such as guide rope and guy winding and coaster skew, after this phenomenon occurs, coaster moves more difficult, and the frictional resistance that guide rope and guy winding and coaster also need to overcome between transmission pressure and crossing frame under shift state could move transmission pressure, be easy to cause the phenomenons such as transmission pressure stagnation, and then affect construction progress and increase the operations such as maintenance capacity, its construction cost obviously improves.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of safe and reliable crossing frame in order to overcome the defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions: a kind of safe and reliable crossing frame, comprise column and cross-arm, described cross-arm is arranged on column, the center line of cross-arm overlaps with the axis line of column, it is characterized in that, described cross-arm is provided with 5, is horizontally set on up and down on column, and every layer of cross-arm is provided with at least two coaster hanging points.
The high 52.3m of described column, described cross-arm comprises five layers from top to bottom, be respectively: ground floor cross-arm, second layer cross-arm, the 3rd layer of cross-arm, the 4th layer of cross-arm and layer 5 cross-arm, described ground floor cross-arm is apart from column top 0.3m, distance between described second layer cross-arm and ground floor cross-arm is 2m, distance between described the 3rd layer of cross-arm and second layer cross-arm is 6.5m, distance between described the 4th layer of cross-arm and the 3rd layer of cross-arm is 7m, and the distance between described layer 5 cross-arm and the 4th layer of cross-arm is 6.5m.
