At the problem defective that prior art exists, the purpose of this utility model provides strides electric railway overpass bridge construction protection canopy on a kind of; Can guarantee to cross over the smooth construction that overpass bridge is built in electric railway, guarantee personal safety and traffic safety, it is simple in structure, construction is easy to make, and little, high efficiency is disturbed in transportation to train.
In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:
Stride electric railway overpass bridge construction protection canopy on described, comprising: column, crossbeam, roof panel and insulating slab; Some columns of both sides are arranged on beyond railway clearance and the electric pole, and two relative columns are provided with crossbeam, and crossbeam is provided with some vertical purlins, is equipped with roof panel on the purlin; Every contact net electrical body top is provided with the all-insulated plate insulating slab, and all-insulated plate is fixed on the purlin by flexible suspension rod; The anti-electric prod of the rear side setting of each electric pole is fixed on the column, and the lower end of column is fixed in the deposited reinforced concrete pile, and is provided with the grounding wire of antistatic.
Stride electric railway overpass bridge construction protection canopy on described, flexible suspension rod comprises: upper hanger, following suspension rod and hoisting rope; The upper end of upper hanger is fixed with hoisting rope, hangs on it on purlin, and the hook cover is built-in with down suspension rod on the lower end of upper hanger; The lower draw-bar cover of following suspension rod is built-in with upper hanger, and upper and lower suspension rod middle part is equipped with some adjustment holes, and adjustment hole is built-in with steady pin; The lower draw-bar of following suspension rod is built-in with vertical slide bar of all-insulated plate.
Stride electric railway overpass bridge construction protection canopy on described, all-insulated plate is that insulating slab is rectangular, and its cross section is curved; All-insulated plate is provided with vertical slide bar.
Stride electric railway overpass bridge construction protection canopy on described, anti-electric prod is fixed on the column for the insulation rod.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
Stride electric railway overpass bridge construction protection canopy on being somebody's turn to do, reasonable in design, can resist the impact of accidentally general purpose tool material tool being fallen in the construction of electric railway overpass bridge, the security reliability height; The suspension of all-insulated plate scalable, the adjustable length of suspension rod that stretches makes that the installation rate of all-insulated plate is fast, and the time that taking has a power failure blocks is short, and is little to the interference of transportation, personal safety and traffic safety in the time of can guaranteeing the bridge crossing construction.
