Description
Technical field
The utility model is related to urban rail transit technology fields, and in particular to one kind rigid contact net system in tunnel
The double pre-buried channel flow overheat rigid suspension apparatus used.
Background technology
Pre-buried channel flow application originates in 1931, has the history of more than 80 years so far.China's rail traffic also has been introduced by
Technique starts the contact network in tunnel installation for being applied to Chinese high ferro, such as military wide high ferro, Harbin-to-Dalian high ferro, capital for 2008
Shanghai high ferro, Hangzhou-Zhejiang high ferro, Shanghai elder brother's high ferro etc..In recent years, city rail traffic also begins to use.At present Shenzhen test section, on
It is used in rigid contact net in the urban subway tunnels such as sea, Tianjin.Single pre-buried channel flow is usually that double bolts connect with conversion cradle
It connects, contact surface is small, and there are the risks of conduit connecting portion deformation；Aerial rigid suspension device is installed using double pre-buried channel flows
Solves the above problem very well.But it is existing lifting the complicated occupied space of suspension apparatus it is big, cost is higher.
Utility model content
In order to solve deficiency of the prior art, provide that a kind of stable connection is firm, and simple and compact for structure, at low cost is outstanding
Device for hoisting, technical solution is used by the utility model：
Double pre-buried channel flow overheat rigid suspension apparatus in a kind of tunnel, including the mounting base that a pair is connect with built-in groove, institute
The mounting base stated is U-shaped, and suspension screw rod is respectively connected in each mounting base, in the suspension screw rod far from mounting base
One end be connected with across the crossbeam hung at two between screw rod, the item that is set along crossbeam length is equipped on the crossbeam
Shape hole, connection again can be along the insulation clamping device of bar hole activity adjustment on the crossbeam.
The mounting base includes connecting fixed fixed part and the connecting portion for installing suspension screw rod with built-in groove,
The fixed part is plate-like and is obliquely installed that the high side in side is low to be matched with tunnel inner wall radian, and the connecting portion is U-shaped
Reserve the installation space of suspension screw rod top nut.
Being equipped on the connecting portion prevents the limit ribs of nut rotation.
The insulation clamping device includes the insulator being mounted on crossbeam, and it is fixed to be equipped with below the insulator
Bit line presss from both sides, and bus-bar is clamped on the registration clamp.
Using the suspension apparatus of above structure due to directly being connected between mounting base and crossbeam by Hanging bolt, reduce
Transition portion occupies little space and is applicable in the smaller tunnel of headroom, and reduce cost, while can pass through Hanging bolt
It realizes that horizontal depth of beam is adjusted, while the lateral adjustments for the bar hole realization insulation clamping device for passing through crossbeam, adjusts more
Add conveniently.
Description of the drawings
Fig. 1 is the utility model front view；
Fig. 2 is the utility model vertical view；
Fig. 3 is mounting base structure diagram.
Specific embodiment
Suspension apparatus as shown in Figure 1 includes a pair of of mounting base 1, and mounting base 1 is U-shaped for connecting fixation with built-in groove,
Mounting base 1 as shown in Figure 3 includes fixed part 1-1 and connecting portion 1-2, and connecting portion 1-2 is U-shaped, and fixed part 1-1 is arranged on connecting portion
The U-shaped opening both ends of 1-2 are plate-like, and connection of the mounting hole for bolt and built-in groove is equipped on fixed part 1-1 and is fixed, is set
Fixed part 1-1 in connecting portion 1-2 both sides is inclined to set and the high side in side is low, surface arc transition, and setting in this way causes
Fixed part 1-1 can be bonded with tunnel top domes so that mounting base 1 is installed more firm, be connected in mounting base 1
Screw rod 2 is hung, suspension screw rod 2 is arranged on connecting portion 1-2, and it is in order to which slot milling is come the company of placement that connecting portion 1-2, which is arranged to U-shaped,
The nut of suspension screw rod 2 is connect, being equipped on the connecting portion 1-2 prevents the limit ribs 6 of nut rotation so that it is convenient to lower section
The nut rotation of suspension screw rod 2 is fixed in connecting portion 1-2 positions during installation, while connects Hanging bolt 2 on connecting portion 1-2 and save
About insufficient space spanner cannot enter the problem of connecting portion 1-2, directly prevent nut rotation by limit ribs 6, will connect
Portion 1-2 make it is U-shaped can also make mounting base 1 have certain elasticity facilitate installation fix, suspension screw rod 2 far from mounting base 1
One end is connected with crossbeam 3, since mounting base 1 and suspension screw rod 2 are respectively provided with a pair, therefore crossbeam 3 across hung at two screw rods 2 it
Between connect, adjusting that is fixed and can carrying out height in vertical direction to crossbeam 3 by nut is connected by nut.Such as figure
Bar hole 4 is provided with shown in 2 on crossbeam 3, bar hole 4 is set along 3 length direction of crossbeam, and insulating blanked clamper is provided on crossbeam 3
Device 5 is held, insulation clamping device 5 is connected to 4 position of bar hole, can realize insulation clamping dress in the horizontal direction along bar hole 4
Put 5 activity adjustment.
The clamping device 5 that insulate includes insulator 5-1, registration clamp 5-2 is equipped with below insulator 5-1, in position line
Bus-bar 5-3 is clamped on folder 5-2.
