Abstract
The utility model discloses a subway rigid suspension contact net bearing structure, include the base with tunnel top rigid coupling to and the lift kits of suspension connection busbar, the base with but be equipped with height -adjusting's strutting arrangement between the lift kits, strutting arrangement includes outstanding hang post, and installs hang the oblique pull rod of hang post both sides, hang the hang post with base fixedly connected, to one side the pull rod with the lift kits rigid coupling, to one side the pull rod with the tie point that hangs the hang post is adjustable on vertical height. The utility model discloses the bearing structure who makes the rigid suspension contact net has the height -adjustable function of festival. Like this can be in time, nimble reply is because whole the deformation takes place for factors such as geological structure, groundwater change, peripheral construction, causes the changing of the relative positions condition of contact net, the assurance busbar accords with the regulation to the distance of rail surface. The utility model discloses save labor time, shortened the time limit for a project, provide sufficient setting for possible deformation of later stage.
Description
Technical field
This utility model relates to rigid suspension catenary, particularly a kind of subway rigid suspension catenary supporting construction.
Background technology
Substantially three kinds of the suspension Lou type of subway overhead type contact net at present: tramway type suspension equip ment, catenary suspension, rigid body hangs.
Its wire thicknesses of different types, bar number, tension force are all different.Bus support device in rigid suspended is to pass through anchor
Bolt is fixed on tunnel top.General crab-bolt uses high strength chemical drift bolt, safe ready.Crab-bolt is tried at installation pulling force to be done
Test.Using this support, can be realized the adjustment of vertical direction by regulation bolt, stagger can lead to the exhausted of adjusting pole
Edge position realizes.The swollen shrinkage of heat of bus-bar realizes by sliding on hanging clip.Due to rail traffic station and tunnel
The unfavorable geology of periphery, it is likely that spot fault is dynamic, differential settlement etc., causes the changing of the relative positions of contact net.Meanwhile, also can occur
Because construction error, cause the situation that the rail road against the wind of installing contact net is inconsistent with designed elevation.Lead at adverse geological condition
Cause the uneven changing of the relative positions of contact network in tunnel, and the rail road absolute altitude against the wind caused because of construction error in station is inadequate, and tunnel
Structure is in the operation in later stage, owing to the factors such as geological structure, groundwater change, periphery construction are likely occurred bulk deformation,
Cause the changing of the relative positions of contact net.And existing rigid suspended formula contact net supporting construction, generally realized vertically by regulation bolt
The adjustment in direction, when the regulation of bolt is highly insufficient to compensate for the changing of the relative positions and the construction error that Geological Reasons produces, needs again
Measure and construction, cause the artificial and waste of material, and affect project progress.
Utility model content
This utility model provides a kind of subway rigid suspension catenary for solving technical problem present in known technology
Supporting construction.
This utility model is adopted the technical scheme that by solving technical problem present in known technology: one subway is firm
Property hang contact net supporting construction, including the base affixed with tunnel top, and hang the suspension holdfast connecting bus-bar, institute
Stating and be provided with height-adjustable support means between base and described suspension holdfast, described support means includes the davit that dangles, with
And it being arranged on the brace of described pendency davit both sides, described pendency davit is affixed with described base, and described brace is with described
Suspension holdfast is affixed, described brace and junction point scalable in vertical height of described pendency davit.
Further, described pendency davit is provided with multiple installing hole, described brace and described pendency in the vertical direction
Davit is by fixing through the bolt of described installing hole.
Further, described pendency davit both sides are provided with connecting plate, described connecting plate be provided with location hole, described brace with
Described connecting plate is by fixing through the bolt in hole, described location.
Further, described base is preset with the installing hole installing described suspension holdfast.
Further, described suspension holdfast Π shape connects bus-bar locating support；Described bus-bar locating support passes through
Regulation bolt is connected with described suspension holdfast.
This utility model has the advantage that with good effect: by the oblique pull of the pendency davit of support means with its both sides
The junction point of bar scalable in vertical height, makes the supporting construction of rigid suspension catenary have Height Adjustable function.
So can tackle in time, flexibly due to factor generation bulk deformations such as geological structure, groundwater change, periphery constructions, cause
The changing of the relative positions situation of contact net, it is ensured that confluxing is discharged to the distance of rail level and meets regulation.When deformation reaches the limit values, can remove outstanding
Hanging post and the brace of its both sides, be directly arranged on suspension holdfast on the base of tunnel top, and the later stage is by regulation bolt
It is adjusted.This utility model can install expansion bolt and steel plate, once mounting at tunnel (rail top) top, can reserve outstanding simultaneously
Hanging post 1 and the installing hole of suspension holdfast, repeated removal, installation, not solid and reliable.Further, owing to reserving pendency davit simultaneously
With the installing hole of suspension holdfast, height adjustment range is big, applied widely.This utility model saves manual time, shortens
Duration, provide sufficient adjustment amount for the deformation that the later stage is possible.
Its major advantage has:
1, guarantee copper contact wire is to rail level in the case of constant, accomplishes rationally to save, and installing space demand is little.
2, two kinds of support meanss can be installed, use different support meanss according to different distortion situation with required precision, should
Wide by scope.
3, same anchor is installed in superstructure, safe and reliable.Block wall does and need to break as the temporary structure later stage
Remove, no matter use which kind of method, all can cause the destruction of the segment structure being joined directly together with block wall, and this utility model will forever
Structure is separated with temporary takeover for a long time, and " double end " designs, and protects the structure that finishes.
4, adjust flexibly, it is achieved the gentle slope regulation of rigid contact net, the vertical weight-bearing function of block wall, horizontal support function
Realized with defencive function time broken.
