Description
Technical field
The present invention relates to technical field of rail traffic, and in particular to a kind of bending-resistant type pre-buried channel flow is suspended vertically base dress
Put.
Background technology
Overhead rigid suspension bus-bar electric power system, it is a kind of important urban rail transit contact network power supply mode,
Through being widely used, and it is suspended vertically the important component that base device is whole rigid electric power system.Existing skill
In art, otherwise it is to be fixed on tunnel top by expansion bolt to be suspended vertically base device；By pre-buried channel flow with T-shaped spiral shell
Bolt is installed.Big using expansion bolt on-site installation work amount, installation reliability is relatively low, progressively by pre-buried channel flow mounting means institute
Substitution.
Conventional vertical suspends base in midair because structure is limited, and causes pre-buried channel flow bending resistance not good enough；In addition, according to design requirement
Hanging bolt needs right angle setting, and tradition suspention base device does not possess regulatory function, and this is just to installation foundation and part sheet
Body proposes higher required precision, is otherwise suspended vertically base device installation rear overhang hanger bolt and is not easy vertically, high-precision requirement
Installation foundation capital construction high expensive.
With the high speed development of electric railway, base device reliability requirement is suspended vertically to overheat rigid also increasingly
It is high, it is desirable to which that it can be securely fixed on pre-buried channel flow, and can improve the non-deformability of pre-buried channel flow, while requires structure
Simply and possess regulatory function, be easily installed, reduce capital construction cost.It is difficult to meet to want it can be seen that being suspended vertically base device
Ask.Therefore, it is necessary to which developing a kind of new-type bending-resistant type pre-buried channel flow is suspended vertically base device.
The content of the invention
The purpose of the present invention is that a kind of bending-resistant type pre-buried channel flow of design is suspended vertically base device, improves pre-buried channel flow fair line
The bending resistance in road direction, when ought particularly meet accident (e.g., bus-bar clamping stagnation), pre-buried channel flow anti-in itself can be improved
Curved ability, avoid pre-buried channel flow deformation failure.And can adjust automatically suspended screw perpendicularity, ensure the vertical peace of suspended screw
Dress.
The technical solution of the present invention：A kind of bending-resistant type pre-buried channel flow is suspended vertically base device, including suspention base
And suspended screw, it is characterised in that：There is the boss and mounting hole that can be embedded in pre-buried channel flow on the upper surface of the suspention base,
And boss is located at mounting hole both sides；The middle part of the suspention base to horizontally suspend plate, and the center for horizontally suspending plate be formed with it is outstanding
Hanging hole, the upper port of the suppending hole are tapered；The suspention base is arranged on pre-buried by T-bolt component through mounting hole
On conduit, the suspended screw is inserted in taper faced washer, spheric washer and locking nut successively after passing through suppending hole from top to bottom, and
The screw head of suspended screw is adapted to the tapered upper end mouth of suppending hole by sphere, the perpendicularity of adjust automatically suspended screw, will
Suspended screw, which is vertically fixed on, to horizontally suspend on plate.
The upper surface of the suspention base coincide for circular arc mounting surface and with tunnel tip circle cambered surface closely connected.
The upper surface width of the suspention base is more than the width of pre-buried channel flow.
The present invention has the advantage that compared with prior art and effect：
1st, mounting surface width of the present invention is wider than pre-buried channel flow, along line direction stress when dispersible load to tunnel wall, carry
High pre-buried channel flow bending resistance.
2nd, the boss on mounting surface of the present invention is easy to suspend in midair the installation positioning of base, convenient installation；Along line direction stress
When, the dispersible T-bolt load of boss, improve pre-buried channel flow bending resistance.
3rd, the present invention by sphere and cone match using can play a part of automatically adjusting, adjust automatically suspended screw
Perpendicularity, ensure the right angle setting of suspended screw.
4th, the present invention being used cooperatively by spheric washer and taper faced washer, increases the frictional force between screw thread, can rise
To certain anti-loose effect.

Embodiment
With reference to a kind of embodiment of the description present invention of accompanying drawing 1,2,3,4.
A kind of bending-resistant type pre-buried channel flow is suspended vertically base device, including suspention base 1 and suspended screw 7, the suspention
There is the boss 1-1 and mounting hole 1-4 that can be embedded in pre-buried channel flow 8, and boss 1-1 is located at mounting hole on the upper surface 1-3 of base 1
1-4 both sides；The middle part of the suspention base 1 is horizontally suspends plate 1-5, and the center for horizontally suspending plate 1-5 is formed with suppending hole 1-
6, the upper port 1-2 of the suppending hole 1-6 is tapered；The suspention base 1 is pacified by T-bolt component 3 through mounting hole 1-4
On pre-buried channel flow 8, the suspended screw 7 is inserted in taper faced washer 4, ball ring successively after passing through suppending hole 1-6 from top to bottom
Circle 5 and locking nut 6, and the screw head of suspended screw 7 is adapted to suppending hole 1-6 tapered upper end mouth by sphere 7-1, automatically
The perpendicularity of suspended screw 7 is adjusted, suspended screw 7 is vertically fixed on and horizontally suspended on plate 1-5.It is described to suspend the upper of base 1 in midair
End face 1-3 is circular arc mounting surface and coincide with tunnel tip circle cambered surface 2 closely connected.The upper surface 1-3 width of the suspention base 1 is big
In the width of pre-buried channel flow 8.
During installation, first T-bolt component 3, suspended screw 7, taper faced washer 4, spheric washer 5 and locking nut 6 are pacified in advance
On outstanding base 1, nut is not first locked, and will suspend base in midair according still further to design requirement is positioned at design attitude, boss 1-1 edges
In pre-buried channel flow, 90 ° of T-bolt is rotated, is made after T-bolt flute profile engages with conduit internal tooth, locking T-bolt component
