Return is dynamic；Described two line slide rails are separately mounted on bottom plate；Each step surface of the fixed station and traveling table it is each
Two hydraulic cylinders are mounted on step surface, because fixed station and traveling table are stepped, therefore installed in fixed station
It is also stepped with a hydraulic cylinder on traveling table；Each hydraulic cylinder on the fixed station is installed in a fixation
On plate, a fixed plate plays a part of a hydraulic cylinder on sizing fixed station, is fixed while a fixed plate also functions to support
The effect of a hydraulic cylinder on platform；The upper end of a number fixed plate passes through two upper support columns and fixed station the top
Step surface is connected, and the lower end of a fixed plate is connected by two lower support columns with the step surface of fixed station bottom,
A number upper support column and a lower support column play a part of supporting a fixed plate；Each hydraulic pressure on the traveling table
Cylinder is installed in No. two fixed plates, and No. two fixed plates play a part of a hydraulic cylinder on sizing traveling table, while No. two solid
Fixed board also functions to the effect of a hydraulic cylinder on support traveling table；The upper end of No. two fixed plates passes through two No. two upper supports
Post is connected with the step surface of traveling table the top, and No. two fixed plates lower end by two No. two lower support columns and traveling table most
The step surface of lower section is connected, and No. two upper support columns and No. two lower support columns play a part of supporting No. two fixed plates；The fixation
A hydraulic cylinder upper end on a hydraulic cylinder and traveling table on platform is all symmetrically mounted on two flexible band steels, due to installing
A hydraulic cylinder on fixed station and traveling table is stepped so that the flexible band steel being mounted above passes through into bridge arch shape
Number the flexible of hydraulic cylinder can control the degree of crook of flexible band steel, so as to have adjusted the shape of institute's bridge construction arch, the scope of application
Extensively；Four horizontal stripes are symmetrically welded between described two flexible band steels, horizontal stripe plays a part of connection and fixing flexible band steel；Institute
The left and right sides for stating fixed station and traveling table is all symmetrically installed with extension apparatus, the extension apparatus include being welded on fixed station or
An ear mount and No. two ear mounts on traveling table side；No. two hydraulic cylinders are provided with by bolt in a number ear mount；It is described
The outer wall of No. two hydraulic cylinders is fixed on a location-plate；A number location-plate is arranged on fixed station or traveling table by screw
On, the operative orientation of No. two hydraulic cylinders is positioned by a location-plate so that piston rod on No. two hydraulic cylinders can only be along
Specific direction is moved；No. three hydraulic cylinders are provided with by bolt in No. two ear mounts；The outer wall of No. three hydraulic cylinders is fixed
