Description
Technical field
The present invention relates to engineering construction machinery technical field, particularly to a kind of for large-scale component integral translation
The pushing tow of stride pushing tow system crosses assembling unit.
Background technology
Successively incremeantal launching method technology is applied in the translation construction of large-scale component the most more and more widely.Structure for large span
In bridge steel box girder incremental launching construction, existing construction method typically uses successively incremeantal launching method or the way dragged, and needs steel case
Beam or beams of concrete external tendon carry out temperature pier, form bridge and release；The form of employing steel strand wires traction, every pushing tow one section,
Steel strand wires need to be reinstalled.The method working procedure is loaded down with trivial details, and cost is high, and can only advance and can not retreat, and repeatedly starts simultaneously
Horizontal thrust or pulling force are unfavorable to the force status of flexible pier.Authorization Notice No. is the disclosure of the invention one of CN 201678949 U
Plant walking type pushing device, including sliding case, slideway, translation jack, jack and correction jack assembly；Sliding case is by sliding
Box main body unit and the sliding box main body connector composition connecting sliding box main body unit, between sliding box main body unit, slide box main body list
It is flexibly connected by bolt between unit and sliding box main body connector and between each sliding box main body connector；Slideway is by slideway main body
Unit, slideway main body connector form, between slideway main unit, between slideway main unit and slideway main body connector, respectively
It is flexibly connected by bolt between slideway main body connector；Sliding case is integrally placed on slideway, in up-down structure, and jack
In the jack mounting cylinder being mounted on slideway, translate the translation jack peace that jack is mounted on slideway
On dress plate, on the correction jack installing rack that correction jack assembly is mounted on slideway, this device is very heavy by translation
Top, the alternation of jack realize walking pushing tow, it is not necessary to steel box-girder or beams of concrete external tendon are faced
Shi Jiagu, is also not required to use steel strand wires.But it has following defects that 1, the structure of slideway, sliding case is complicated and volume is big, weight
Weight, difficulty of processing is big, and cost is high, and required work space is big.2, each pushing tow unit needs 4 jacks and 4 pushing tows thousand
Jin top, not only equipment cost is high, and required work and accommodation space are big, it is impossible to realizing I-beam and bolt splicing construction
Component pushing tow.
Summary of the invention
It is an object of the invention to provide one and component need not be carried out temperature pier, it is not necessary to use steel strand wires, equipment one
Bridge construction expense can need not can be saved because of steel strand wires length midway disassemblerassembler not until completion after secondary installation；Device systems
By slide surface by changing between incremental launching device and slide plate bottom box beam, ball head device installed by vertical lifting jack simultaneously, can be certainly
Dynamic centering avoids the damage bottom box beam and jack lateral force, simultaneously during pushing tow bridge pier not by horizontal loading, component
With bridge pier all without damage, structure is made to guarantee safety during pushing tow；Overcome conventional tractive manner can only advance and can not retreat
Shortcoming, when pushing tow runs into element joints or other situation still can carry out the pushing tow of stride pushing tow system of incremental launching construction
Cross assembling unit.
The solution of the present invention is such that
The pushing tow of a kind of stride pushing tow system and lowering or hoisting gear, including thrustor, lowering or hoisting gear, described thrustor includes
Being fixed on the reaction frame of pushing tow unit platforms, sliding case, horizontal pushing tow jack, the most horizontal pushing tow jack is to utilize reaction frame
As counter-force fulcrum, described lowering or hoisting gear is supported on sliding case, and lowering or hoisting gear is connected to level jack, is formed by level jack
Push the slide construction that lowering or hoisting gear moves along sliding case inner slide；Described lowering or hoisting gear is fixed with jack, and jacking is very heavy
Top, top is connected with bulb flat, and bulb flat top is connected with fishback, and fishback top is supported on the bottom of component by backing plate；
Described fishback top is provided with groove along component moving direction, and the width of this groove is more than the width of member bottom section ridge.
More specifically technical scheme also includes: described lowering or hoisting gear is fixed with jack, jack top with
Bulb flat connects into the structure that sphere tongue and groove connects or cambered surface tongue and groove connects so that bulb flat is able to put along spherical
Dynamic, carry out the adjustment of Automatic Levelling and the flexible adjustment in direction；Bulb flat top is connected with fishback, and fishback top is by pad
Plate is supported on the bottom of component.
Further: described bulb flat uses tongue and groove attachment structure with fishback, from front, rear, left and right four direction pair
Fishback carries out spacing.
It is an advantage of the invention that and component need not be carried out temperature pier, it is not necessary to use steel strand wires, after equipment once mounting i.e.
Bridge construction expense can need not can be saved because of steel strand wires length midway disassemblerassembler not until completion；Device systems by slide surface by
Changing to bottom box beam between incremental launching device and slide plate, ball head device installed by vertical lifting jack simultaneously, can automatic centering avoid
To the damage bottom box beam and jack lateral force, during pushing tow, bridge pier is not by horizontal loading, component and bridge pier the most simultaneously
Can damage, make structure guarantee safety during pushing tow；Overcome conventional tractive manner can only advance the shortcoming that can not retreat, work as top
Push away and run into element joints or other situation still can carry out incremental launching construction.
