Mobile 312 at a distance from vertical jacking apparatus 20 be less than bridge member need adjust range when, the second driving should be made
312 transverse direction B forward direction of mobile in mechanism 32 retracts, to prevent the second driving mechanism 32 to the lateral B of vertical jacking apparatus 20
Forward direction movement causes to hinder；Equally, the mobile 312 in the second driving mechanism 32 is pushing vertical 20 transverse direction B of jacking apparatus anti-
To when movement, the mobile 312 in the second driving mechanism 32 is less than bridge member at a distance from vertical jacking apparatus 20 and needs to adjust
When the range of section, the 312 transverse direction B backtracking of mobile in the first driving mechanism 31 should be made, to prevent the first driving mechanism
The lateral B reverse movement of 31 pairs of vertical jacking apparatus 20 causes to hinder.Due to third driving mechanism 41 and the 4th driving mechanism 42
It is located at the two sides of vertical jacking apparatus 20 on longitudinal C, when the mobile 312 in third driving mechanism 41 is pushing vertical jacking
When 20 longitudinal direction C forward direction of device is mobile, the mobile 312 in the 4th driving mechanism 42 is less than bridge at a distance from vertical jacking apparatus 20
When the range that beam needs to adjust, the 312 longitudinal direction C forward direction of mobile in the 4th driving mechanism 42 should be made to retract, to prevent
4th driving mechanism 42 causes to hinder to longitudinal C forward direction movement of vertical jacking apparatus 20；Equally, in the 4th driving mechanism 42
Mobile 312 when pushing vertical 20 longitudinal direction C of jacking apparatus reverse movement, mobile 312 in third driving mechanism 41 with erect
When being less than the range that bridge member needs to adjust to the distance of jacking apparatus 20, the mobile in third driving mechanism 41 should be made
312 longitudinal direction C backtrackings, to prevent third driving mechanism 41 from causing to hinder to longitudinal C reverse movement of vertical jacking apparatus 20.
It should be appreciated that the first driving mechanism 31, the second driving mechanism 32, third driving mechanism 41 and the 4th driving mechanism
42 are not limited solely to said mechanism, in other specific embodiments, the first driving mechanism 31, the second driving mechanism 32, third
Driving mechanism 41 and the 4th driving mechanism 42 can also be other structures, such as hydraulic cylinder.
In the present embodiment, four driving mechanisms and the relative position of support base 10 are fixed, therefore, in first driving device 30
The first driving mechanism 31 and the second driving mechanism 32 with vertical jacking apparatus 20 do not have determining connection relationship, simply by
The mode of contact pushes the vertical jacking apparatus 20 mobile, to guarantee third driving mechanism 41 in the second driving device 40 and the
Four driving mechanisms 42 can push vertical jacking apparatus 20 mobile.In other specific embodiments, as shown in figure 5, the first driving
Device 30 and the second driving device 40 can also be directly directly connected to vertical jacking apparatus 20, while make first driving device 30 can
Mobile is set on support base 10, and the second driving device 40 is movably arranged on support base 10, works as first driving device
When the 30 vertical 20 transverse direction B of jacking apparatus of driving are mobile, the second driving device 40 also follows the opposite support base of vertical jacking apparatus 20
10 transverse direction B are mobile, when the second driving device 40 drives vertical 20 longitudinal direction C of jacking apparatus to move, first driving device 30 also with
It is mobile relative to 10 longitudinal direction C of support base with vertical jacking apparatus 20.
Further, in this embodiment vertical jacking apparatus 20 includes pedestal 21 and jacking part 22, pedestal 21 is placed in branch
Support face 121, jacking part 22 are detachably connected with pedestal 21.Pedestal 21 is placed on supporting surface 121, guarantees entire vertical jacking dress
Setting 20 has biggish contact area with supporting surface 121, meanwhile, it is flat on supporting surface 121 to improve vertical jacking apparatus 20
Stability.Further, since jacking part 22 is detachably connected with pedestal 21, it, can be individually right after pedestal 21 or jacking part 22 are impaired
Jacking part 22 is replaced with pedestal 21.
First driving device 30 when pushing vertical 20 transverse direction B of jacking apparatus to move, in first driving device 30 first
Driving mechanism 31 and the second driving mechanism 32 directly act on pedestal 21, to guarantee vertical jacking apparatus 20 in supporting surface 121
Stability when upper transverse direction B is mobile；Second driving device 40 is when pushing vertical 20 longitudinal direction C of jacking apparatus mobile, the second driving
Third driving mechanism 41 and the 4th driving mechanism 42 in device 40 directly act on pedestal 21, to guarantee vertical jacking apparatus
20 stability when longitudinal direction C on supporting surface 121 is mobile.
In the present embodiment, pedestal 21 includes bottom plate 211 and multiple coaming plates 212, and multiple 212 circumferentially-spaceds of coaming plate are the bottom of in
211 upper surface of plate, multiple coaming plates 212 define a located space jointly, and jacking part 22 is placed in located space.Specifically, originally
In embodiment, coaming plate 212 is four, and two adjacent coaming plates 212 are in a circumferential direction at a distance of 90 degree.
After bridge member is placed on jacking part 22, the jacking work of part 22 can jack bridge member, to bridge
Component is adjusted for height and position.After jacking part 22 is placed in located space, there is 212 pairs of jacking parts 22 of coaming plate constraint to make
With guaranteeing to jack after part 22 is connect with pedestal 21 has good stability.This 21 structure of pedestal is simple, can easily realize
Jack the dismounting of part 22 and pedestal 21.
Certainly, not only above structure pushes up the removably of jacking part 22 and pedestal 21 in other specific embodiments
Rising part 22 can also realize with pedestal 21 detachably by other means, for example, jacking part 22 and pedestal 21 can by screw realization
Dismantling connection.
It should be appreciated that jacking part 22 can be various structures, for example, hydraulic cylinder, hydraulic jack etc..The present embodiment
In, jacking part 22 is hydraulic jack.
Further, in this embodiment the bottom of vertical jacking apparatus 20 is equipped with smooth part 70, smooth part 70 has smooth
Face, shiny surface are contacted with supporting surface 121.Specifically, smooth part 70 is plate structure, and smooth part 70 is set to vertical jacking apparatus
The lower surface of the bottom of 20 pedestal 21, smooth part 70 is shiny surface.In the present embodiment, the material of smooth part 70 is polytetrafluoro
Ethylene.
The shiny surface of smooth part 70 is contacted with supporting surface 121, to effectively reduce vertical jacking apparatus 20 and supporting surface 121
Between frictional force so that vertical jacking apparatus 20 after lateral B or longitudinal direction C power on supporting surface 121 by more easily moving.
These are only the preferred embodiment of the present invention, is not intended to restrict the invention, for those skilled in the art
For member, the invention may be variously modified and varied.All within the spirits and principles of the present invention, it is made it is any modification,
