Tightly, the high requirement of required precision is always spelled, and segment girder steel weighs 1800T, spatial position adjustment difficulty is big, and therefore, it is necessary to mention
Three-dimensional regulating device is always spelled for a kind of novel whole segment steel girder segment of large-tonnage, it is numerous to solve existing regulating device operation
It is trivial, the low problem of work efficiency.
Utility model content
Its purpose of the utility model, which is that, provides a kind of whole segment girder steel precision three-dimensional adjustment of large-tonnage, solves existing
Regulating device it is cumbersome, the low problem of work efficiency, have can carry out simultaneously on tri- directions whole segment girder steel X, Y, the Z of large-tonnage
Adjustment, can also single direction be adjusted, regulate the speed fast, the high feature of work efficiency.
It adopts the technical scheme that achieve the above object, a kind of whole segment girder steel precision three-dimensional adjuster of large-tonnage,
Including chassis, pedestal, stainless steel plate and MGE plate, the vertical and horizontal difference on chassis are successively arranged between the chassis and pedestal
Equipped with longitudinal jack, lateral jack, pedestal is equipped with vertical jack, and vertical jack is equipped with the super backing plate of steel, steel
It makes and rubber support is set on super backing plate, rubber support is equipped with whole segment girder steel, and the row of vertical jack is controlled by applying external force
Journey, it is different using the MGE plate under girder steel and rubber support and pedestal and the coefficient of friction between stainless steel plate, make whole segment
Girder steel is moved along tri- directions X, Y, Z simultaneously in assembled moulding bed, can also be adjusted along single direction, be realized the three of whole segment girder steel
The adjustment of dimension space position.
Beneficial effect
The utility model has the following advantages that compared with prior art.
The utility model has the advantages that can always be spelled on moulding bed in whole segment girder steel while adjust girder steel along X, Y, Z tri-
The position in direction, easy to operate, effect is fast, and precision is high, while could be applicable to the adjustment of girder steel incremental launching construction girder steel, is applicable in model
It encloses wide.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the utility model overall structure vertical design schematic diagram；
Fig. 2 is the A-A cross-sectional view in Fig. 1；
Fig. 3 is the B-B cross-sectional view in Fig. 1；
Fig. 4 is the planar design schematic diagram on chassis；
It is as shown in the figure: 1. chassis, 2. pedestals, 4. rubber supports, 5. stainless steel plates, 6.MGE plate, the super backing plate of 7. steels, 8.
Lateral jack, 9. longitudinal jack, 10. vertical jack, 11. chassis plates, 12. jack counter-force seats, 13 limit steel plates.
Specific embodiment
The present apparatus includes that chassis 1, pedestal 2 are successively arranged stainless between the chassis 1 and pedestal 2 as Figure 1-Figure 4
Steel plate 5 and MGE plate 6, the vertical and horizontal on chassis 1 are respectively equipped with longitudinal jack 9 and lateral jack 8, and pedestal 2 is equipped with perpendicular
To jack 10, vertical jack 10 is equipped with the super backing plate 7 of steel, and rubber support 4, rubber support 4 is arranged on the super backing plate 7 of steel
It is equipped with whole segment girder steel, the stroke of vertical jack 10 is controlled by applying external force, utilizes girder steel and rubber support 4 and bottom
The coefficient of friction between MGE plate 6 and stainless steel plate 5 under seat 2 is different, makes at whole segment girder steel supporting-point simultaneously in assembled tire
Tri- directions X, Y, Z of frame are mobile, and each fulcrum is equipped with this three-dimensional adjuster, realizes the three-dimensional spatial position tune of whole segment girder steel
It is whole.
The chassis 1 includes chassis plate 11, jack counter-force seat 12, limit steel plate 13, is welded on the chassis plate 11
Jack counter-force seat 12 and limit steel plate 13 are connect, the vertically and horizontally displacement of girder steel is limited.
Embodiment
A kind of whole segment girder steel of purlin chip 1800T carries out segment using 4+1 round and always spells, after the completion of each round is always spelled,
First three segment need to be transported successively, leave the click-through that the last one segment is displaced to moulding bed as female beam of next one
Total spelling of the next round of row need to guarantee female Liang Yi in order to ensure smooth installation of the whole segment girder steel of large-tonnage at bridge location
Space multistory situation is identical as the standing state before movement behind position, due to the influence of all kinds of factors during tread flaking, it is impossible to
Guarantee that the front and back state of female beam is completely the same, therefore the spatial position of female beam must be adjusted.In female Liang Yizhi moulding bed
After starting point, using the whole segment girder steel precision three-dimensional adjuster of large-tonnage, according to whole segment beam section weight 1800t, 4 are equipped in female beam bottom
A whole segment girder steel precision three-dimensional adjuster of large-tonnage, jack of each adjuster equipped with vertical 500T, in length and breadth 100T
Jack, the rubber support of 500T, 4mm thickness stainless steel plate and 25mm thickness MGE plate, according to IN-CHECK Technology of Precision Measurement point
The measurement error of analysis, determine girder steel longitudinally, laterally with the displacement of vertical direction.When moving to moulding bed starting point due to female beam tread flaking, indulge
Lateral displacement variable quantity is generally little, therefore can limit steel plate by setting, and the displacement for avoiding girder steel from adjusting is excessive, while can also
Pedestal is avoided to slide from chassis.When female beam only has transverse direction X displacement to deviate, lateral jack is manipulated, girder steel edge can be made
Transverse shifting adjustment manipulates longitudinal jack and carries out longitudinally adjusted, Dang Muliang when female beam only has Y displacement in longitudinal direction to deviate
When vertical position Z changes, it is adjusted by manipulating vertical jack, it, can also be with when three directions require adjustment
It is adjusted simultaneously, the speed of whole segment girder steel adjustment is fast, and effect is high.
