Description
Technical field
The utility model is related to single line bullet train tunneling technique field more particularly to low headroom tunnel modified contact nets
Hang mechanical structure.
Background technology
Davit adds flat inclined cantilever mode using simple chain suspension, with unification, zero outside speed-adaptive height, structure and tunnel
The advantages of part manufacturing technology is ripe, the supply of material is convenient, construction maintenance is simple is the mode for adapting to modern electrical railway development.It is right
For double -coil output, since tunnel upper clearance is bigger, almost all adds bracket hang using davit.
But for single-track tunnel, since tunnel upper clearance is relatively low, mostly using the relatively low suspension side of other velocity adaptives
Formula.Therefore, it by the way that flat inclined cantilever mode is added to carry out Upgrading to davit, reduces the mounting means and tunnel headroom height is wanted
It asks, makes it is suitable for single-track railway low headroom tunnel, there is very high engineering application value.
Utility model content
The technical problem to be solved by the utility model is to provide one kind to make full use of tunnel top arc area, appropriate to lift
Peaceful bracket reaches the low headroom tunnel modified overhead contact line mechanical structure for reducing tunnel headroom height purpose.
To solve the above problems, low headroom tunnel modified overhead contact line mechanical structure described in the utility model,
It is characterized in that：The structure includes the Horizontal Cantilever and inclined cantilever that are fixed on the davit of tunnel top and are connected with the davit；It is described
Horizontal Cantilever is connected by bushing double eye with the inclined cantilever, which is equipped with locating ring；Described sleeve pipe ears are connected with band and hold
The pipe cap nylon of power rope seat；The locating ring is connected with the positioning pipe with pipe cap, the located pipe clamp of the positioning pipe, band support pipe clamp
The positioning pipe support of son is connected with the pipe cap nylon；The positioning pipe is connected with groupings setters, which sets
There is registration clamp.
The Horizontal Cantilever is equipped with rod insulator I, and passes through single upper bed-plate and be connected with the top of the davit.
The inclined cantilever is equipped with rod insulator II, and passes through single lower bottom base and be connected with the lower part of the davit.
The utility model has the following advantages compared with prior art：
1st, it is installed since the overhead contact line mechanical structure of design is passed through single upper bed-plate and davit by the utility model（It is attached
It）In tunnel top, overcome traditional structure electric pole is installed on ground and in tunnel constructional difficulties problem, while also reduce
The holistic cost of overhead contact line mechanical structure；
2nd, Horizontal Cantilever is designed as inclined mounting structure in the overhead contact line mechanical structure of the utility model design, different
In traditional Horizontal mounting arrangements, the advantage is that：Inclined mounting structure takes full advantage of tunnel top arc space, full
Under the premise of sufficient air insulation clearance, track clearance constraints, tunnel clear height is reduced to the maximum extent, is reduced tunnel and is broken
Face excavation project reduces project cost；The inclined mounting structure of Horizontal Cantilever simultaneously, makes it have certain self-cleaning function, can
Reduce cleaning frequency；In addition the inclined mounting structure of Horizontal Cantilever, making its carrying, pulling force ability enhances vertically downward.
3rd, the utility model meets 160km/h passenger trains in static characteristic and is needed in low headroom tunnel by stream
It asks, is of very high actual application value.
