Scratch, nose girder front end can be led to normal cannot to cross pier；And existing cross pier device generally all coordinate existing nose girder and design,
There is a problem of that pier was difficult.
Utility model content
This utility model offer is a kind of to ensure that the steady walking pushing tow Steel Continuous Box beam nose girder crossing pier in nose girder front end
Cross pier combination unit.
The technical solution adopted in the utility model is：Pier combination unit crossed by a kind of walking pushing tow Steel Continuous Box beam nose girder,
Including three-level inverted steps formula nose girder, walking type pushing device and cushion block；Described walking type pushing device is arranged on three-level inverted steps
Formula nose girder lower second level ladder correspondence position；Cushion block includes being separately positioned on three-level inverted steps formula nose girder lower first level ladder
Correspondence position, adjustable for height first cushion block and be arranged on three-level inverted steps formula nose girder lower third level ladder correspondence position, height
Spend adjustable second cushion block；It is provided with screw jack between first cushion block and three-level inverted steps formula nose girder.
Further, the high 510mm of first order ladder, the long 1927mm of described three-level inverted steps formula nose girder, second level ladder
High 1019mm, long 1700mm, third level ladder is that base plate is consistent with nose girder agent structure.
Further, described first cushion block and the second cushion block are provided with polylith, are applied in combination.
Further, described screw jack is 100t screw jack.
Further, it is provided with support buttress between described walking type pushing device and three-level inverted steps formula nose girder 1.
The beneficial effects of the utility model are：
（1）The special construction of this utility model nose girder front end, can offset by the steel box-girder lower flexure strain that causes of deadweight it is ensured that
Pier steadily crossed safely by girder；
（2）This utility model is using the outer power cooperation jack up girder of screw jack it is ensured that the jacking of nose girder front end is in stably
In controlled scope；
（3）This utility model structure is simple, easy to use, and can reduce the laying of camber when processing in field, reduces
Construction quantity control difficulty of construction.
Brief description
Fig. 1 is this utility model structural representation.
In figure：1- three-level inverted steps formula nose girder, 2- walking type pushing device, 3- screw jack, 4- first cushion block, 5-
Two cushion blocks, 6- distribution beam.
Specific embodiment
With specific embodiment, this utility model is described further below in conjunction with the accompanying drawings.
As shown in figure 1, pier combination unit crossed by a kind of walking pushing tow Steel Continuous Box beam nose girder, lead including three-level inverted steps formula
Beam 1, walking type pushing device 2 and cushion block；Described walking type pushing device 2 is arranged on three-level inverted steps formula nose girder 1 lower section second
Level ladder correspondence position；Cushion block includes being separately positioned on three-level inverted steps formula nose girder 1 lower first level ladder correspondence position, highly
Adjustable first cushion block 4 and be arranged on three-level inverted steps formula nose girder 1 lower third level ladder correspondence position, adjustable for height second
Cushion block 5；It is provided with screw jack 3 between first cushion block 4 and three-level inverted steps formula nose girder 1.
During use, device is arranged in distribution beam 6, turns down the second cushion block 5 height first, adjusts pushing tow forward stroke,
Three-level inverted steps formula nose girder 1 second level ladder is made to cross walking type pushing device 2, then will by walking type pushing device 2 oil return
Beam body falls on the second cushion block 5；With screw jack 3 by three-level inverted steps formula nose girder 1 front end jack-up upwards, eliminate three-level and fall rank
Ladder type nose girder 1 downwarp；Adjustment screw jack 2 stroke, three-level inverted steps formula nose girder 1 beam bottom is higher than walking jack 2；In spiral shell
When rotation jack 3 jacking rises more than three-level inverted steps formula nose girder 1 one section ladder height, in three-level inverted steps formula nose girder 1 and stride
Between formula thrustor 2, setting supports buttress, and heightens the second cushion block 5 simultaneously, and three-level inverted steps formula nose girder 1 beam bottom is fallen second
On cushion block 5；Using walking type pushing device 2 pushing tow three-level inverted steps formula nose girder 1, three-level inverted steps formula nose girder 1 beam bottom reaches step
Behind shoe formula jack 2 top, completed pier technique.
Further, the high 510mm of first order ladder, the long 1927mm of described three-level inverted steps formula nose girder 1, second level ladder
High 1019mm, long 1700mm, third level ladder is that base plate is consistent with nose girder agent structure；Its ladder height is counted according to according to midas
The downwarp data setting calculated.
Further, described first cushion block 4 and the second cushion block 5 are provided with polylith, are applied in combination.
Further, described screw jack 3 is 100t screw jack；Its dimensions meets site requirements, meets
Maximum lifting height is the technical specification of 400mm, and screw jack 3 spiral angle is little, self-locking property is good, can after the weight of top from
Dynamic braking and self-locking.
This utility model using inverted steps formula nose girder and screw jack combinative structure it is ensured that three-level inverted steps formula is led
Beam 1 front end is steady under the unfavorable operating mode meeting with deadweight and linear comprehensive impact generation downwarp to cross pier.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all this
Any modification, equivalent and improvement made within the spirit of utility model and principle etc., should be included in this utility model
Protection domain within.
