Abstract
The utility model discloses an overhead contact rail insulating suspension device which comprises an insulating base and an insulating clamping jaw connected with the insulating base. An insulating sliding rail used for fixing a steel aluminum composite rail is arranged in the insulating clamping jaw, a cavity corresponding to the steel aluminum composite rail is formed in the inner side of the insulating siding rail, and the insulating base and the insulating clamping jaw are buckled in a tooth shape and are connected through three sets of bolts. The insulating sliding rail is embedded in a T-type groove of the insulating clamping jaw, and connecting threaded holes used for being connected with a fixing end are formed in the upper end of the insulating base. The overhead contact rail insulating suspension device has the advantages that the fact that the height in the perpendicular line direction is adjustable is achieved; displacement variation caused by the thermal expansion and cold contraction of the steel aluminum composite contact rail is adapted; failure and slip in the vertical line direction is prevented by the limiting grooves of the insulating base, and the overall structure of the overhead contact rail insulating suspension device meets the mechanical requirements and the electrical requirements of the system; bolt connecting is adopted by the whole set of device, mounting is convenient and fast, interchangeability of products is good, and construction is easy.
Description
Technical field
The utility model relates to the track traffic bracing or strutting arrangement, is specially the built on stilts contact rail insulated suspension device that is applicable to built on stilts contact rail suspention steel-aluminum conductor rail.
Background technology
Adopting steel-aluminum conductor rail is a kind of important power supply of urban orbit traffic mode for locomotive provides electric energy, and line arrangement adopts the upper and lower contact current collection mode of the 3rd rail usually.
How no matter the upper and lower contact current collection mode of existing the 3rd rail arranged, all is installed in walking rails next door one side, increased horizontal gauge and insulating space, so that daily system maintenance risk improves the poor stability of total system.
The utility model content
Technical problem to be solved in the utility model provides built on stilts contact rail insulated suspension device, realize in the tunnel, the external rail-engaging system power supply in tunnel, adopt built on stilts contact rail insulated suspension device, carry out the suspention of steel-aluminum conductor rail and install, realize contacting under suspention the 3rd rail and flowed.
For solving the problems of the technologies described above the technical scheme that the utility model provides:
The utility model is maked somebody a mere figurehead contact rail insulated suspension device, the insulation claw that comprises insulating base and be connected with insulating base, be provided for the fixedly insulation slide rail of composite conductor rail of steel and aluminum in the described insulation claw, insulation slide rail inboard has the cavity corresponding with composite conductor rail of steel and aluminum, profile of tooth interlocks between insulating base and the insulation claw, and vertical direction arranges position-limited trough and cooperates, and connects by three groups of bolts; The insulation slide rail is embedded in the T-shaped groove of insulation claw, and described insulating base upper end has be used to the connecting screw hole that is connected and fixed end.
Be applied in the tunnel, described fixed end is pre-buried channel flow, is connected with the connecting screw hole of insulating base upper end by bolt, nut.
Be applied to H t shore or square beam outside the tunnel, described fixed end is connecting angle, is connected with the connecting screw hole of insulating base upper end by bolt, nut.
Be applied to tunnel outer ring crossbeam, described fixed end is the U bolt, cooperates with the connecting screw hole of insulating base upper end by nut to be connected.
Using method:
One, built on stilts contact rail insulated suspension device self is installed
The insulation slide rail is merged gluing mode and insulation claw closely, firmly be connected by close-fitting, again insulating base is connected with three groups of bolts with the claw that insulate, penetrate pad, nut, pre-load nut.Notice that profile of tooth cooperates between insulation claw and the insulating base.
Two, the installation between built on stilts contact rail insulated suspension device and the contact rail
Steel-aluminum conductor rail is penetrated the insulation slide rail place of built on stilts contact rail insulated suspension device, adjust successively the bolted between connecting angle, the U bolt outside pre-buried channel flow in insulating base and the tunnel or the tunnel; And adjust insulating base and the suitable profile of tooth cooperation position of the claw that insulate, the bolt between pretension insulating base and the insulation claw; At last with all bolted and reach the moment requirement.
Good effect of the present utility model is being: 1) adopt pre-buried channel flow to be connected with insulating base in the tunnel, adopt connecting angle or U bolt (to adopt connecting angle when H t shore, square beam outside the tunnel, adopt the U bolt during circular crossbeam) be connected with insulating base, realize that the height of horizontal path direction is adjustable; Is connected by profile of tooth between insulating base and the insulation claw, the height of realization horizontal path direction is adjustable.
2) at the contact surface place of insulation claw and steel-aluminum conductor rail, the insulation slide rail is set, so that composite conductor rail of steel and aluminum fair line road direction is easy to play, adapts to the displacement change that steel-aluminum conductor rail produces because expanding with heat and contract with cold.
3) position-limited trough of insulating base prevents the inefficacy slippage of vertical line direction.The integral structure of device satisfies machinery, the electric requirement of system.
4) package unit is all with bolts, and it is convenient to install, and product interchangeability is good, is easy to construction.
