It is connected, horizontally arranged scalable needle beam is provided with the downside of adjustable curvature template, scalable needle beam is arranged on a left side
On the upper longeron of right both sides, the upper longeron of the left and right sides is symmetricly set on chassis, the upper side rail inner of the left and right sides respectively with
One end connection of horizontal thrust oil cylinder, the other end of horizontal thrust oil cylinder are connected with chassis.
Described scalable needle beam is set to two sections, has been bolted between two sections and has removably widened needle beam,
The outer end of scalable needle beam is connected by hinging pin shaft with adjustable curvature template.
Described chassis lower end, which is provided with, increases seat.
The modular template of adjustable curvature is used at the top of chassis, meet railway list two-wire radius change scope 500mm~
The Varied section construction of 1500mm curature variation, passes through changing for the flexible action chord length for realizing section arc of scalable needle beam
Become, side template rotates the fitting for realizing section variation, and bottom increases seat and adapted to the height adjustment that section variation is brought, bottom
Small arc mould meets the adjustment that the change of section arc length brings arc length, and more traditional template of untiing widens block and multiple positions
Widen the construction method of block, there is larger facility, simultaneously for trumpet-like tunnel front and rear cross section regulation also have be easy to
The characteristics of realizing, big side can be adjusted with side and adjusts small or does not adjust, is had just for the lining construction for changing section repeatedly
The characteristics of profit is safe and reliable.
Traditional one circulation of Varied section chassis installing/dismounting needs the people of model sheetinstallat work 5, and a cycle installation dismounting is pacified again
Filling locating template needs 18 working days.The utility model needs model sheetinstallat using one circulation of modular chassis installing/dismounting
The people of work 2, locating template is installed in a cycle installation dismounting again needs 2 working days.The modular trolley formwork, it is not necessary to change
Installing/dismounting template, construction period is shortened, practical performance is preferable, simple in construction, and stress is clear and definite, and use is also easy.

Embodiment
To make the technical problems to be solved in the utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And specific embodiment is described in detail.
As shown in figure 1, a kind of railway modular Varied section chassis, including chassis 12 in orbit is set, chassis 12 is left
Right both sides are connected by changing long filament rod sleeve 11 with side template 8 respectively, and the bottom of side template 8 is hinged with the small arc mould 10 in bottom, left and right
Two pieces of adjustable curvature templates 1 are connected between the side template 8 of both sides, are connected between two pieces of adjustable curvature templates 1 by connecting plate 2
Fixed, the downside of adjustable curvature template 1 is provided with horizontally arranged scalable needle beam 3, and scalable needle beam 3 is arranged on left and right
On the upper longeron 5 of both sides, the upper longeron 5 of the left and right sides is symmetricly set on chassis 12, and the inner side of upper longeron 5 of the left and right sides is respectively
It is connected with one end of horizontal thrust oil cylinder 6, the other end of horizontal thrust oil cylinder 6 is connected with chassis 12.
Described scalable needle beam 3 is set to two sections, has been bolted between two sections and has removably widened needle beam
7, the outer end of scalable needle beam 3 is connected by hinging pin shaft 4 with adjustable curvature template 1.
The described lower end of chassis 12, which is provided with, increases seat 9.
The generally 10mm plates of adjustable curvature template 1 are externally reinforced, and ［ 20a channel-section steel frames, connecting plate use 12mm plates, adjustable song
The top plate face of rate template 1 is that entirety connecting plate is connected, it is necessary to when changing curvature, unclamps connecting plate, and adjustable curvature template 1
The scalable needle beam 13 of lower section（It is general to use ［ 20a channel-section steels or ［ 25a channel-section steels）, it is hinged between template using hinge pin
（Typically it is considered as Φ 60mm diameter pintles）, the upper longeron of needle beam bottom consolidation, promote template to change by horizontal thrust oil cylinder 6
Variable curvature, increase or reduction chord length, horizontal thrust oil cylinder 6, which promotes scalable needle beam 13 to reach template chord length, needs chord length
When, inserted among scalable needle beam 13 and widen needle beam 7, lock the connecting plate of die head.Then side template is strutted to connect
The nearly theoretical profile for expanding section, error are in the range of 0mm~+20mm, and seat 9 is increased in lifting integral trolley installation, then installs bottom
The small arc mould in portion bottom, finally installation change long filament rod sleeve 11, template are fixed on stand.Chassis detection positioning after stretching over the ground
Screw mandrel, locking screw and anti-sidesway screw mandrel, concrete perfusion, after the completion of, about 24 hours, support screw is unclamped, shrinks side template,
Side template inwardly rotates disengagement concrete, falls chassis, running truck to next station, form coating, positioning, starts next ring
Section construction.After the completion of section construction is expanded, the small arc mould in bottom is first removed, seat 9 is increased in dismounting, and contraction rotates back to side template
Contracting, chassis is fallen, release the fixation post between adjustable curvature template 1 and scalable needle beam 13, unclamp scalable small horizontal stroke
Beam 13 and the connecting bolt for widening needle beam 7, the connecting plate 2 at the top of adjustable curvature template 1 is unclamped, promotes horizontal thrust oil cylinder 6
Stretch out, needle beam 7 is widened in taking-up, withdraws horizontal thrust oil cylinder 6, and scalable needle beam 13 returns to standard section position, checks
Top template section, locking connecting plate, consolidation post and needle beam, carries out the construction of standard section.
Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of principle described in the utility model is not departed from, some improvements and modifications can also be made, these improvement
The scope of protection of the utility model is also should be regarded as with retouching.
