Background technique
Currently, with the development of rail traffic, the design of the routes such as domestic city rail traffic such as light rail, middle low speed magnetic suspension
More and more use monorail transit mode.PC track girder is monorail transit one of the most common type type, PC track continuous beam because
Have many advantages such as that deformation is small, rigidity is big, expansion joint is few, driving is steady comfortable, maintenance is simple, shock resistance is strong and extensive
Applied in Construction of Urban Rail Traffic.PC track continuous beam is the continuous span of variable cross-section (And of Varying Depth), and beam bottom is bent
Line is circular curve or second-degree parabola, and beam body length changes according to the difference of route bridge span, structure is similar but length not
Together.It since PC track girder had not only been subject to the load-carrying members of train load, but also is train driving track and system equipment channel,
Therefore it, which has the stability of template and all more other bridges of required precision, is significantly promoted.
Prefabricated construction, the mode that bed die generallys use are as follows: by bed die template are carried out to the bridge of this variable cross-section, elongated degree
It is divided into the segment of multiple and different length, needs again to split each segment according to beam type shape, rearrange combination, make it
Meet the construction of bridge.This process for splitting and reconfiguring needs to spend a large amount of manpower and material resources, meanwhile, because bed die is vertical
Any variation is needed to position, the fixed form of bed die is also a big difficulty.The current most common dismounting combination is by rising
Heavy equipment lifts to dismount template section by section, and the fixation of bed die is welded admittedly directly between pedestal after manually adjusting in place
Calmly, by weld seam gas cutting or removing when dismounting, repeatedly.Existing structure mode location difficulty, fixed form fall behind, construction efficiency
Low and molding effect is poor.
Utility model content
When fixed the purpose of this utility model is to provide a kind of bed die can multiple degrees of freedom limit, bed die can walk certainly when adjusting

Entirety is detachably connected as by bolt and nut between person, the both ends bottom surface of attachment beam 22 is respectively placed in corresponding side vertical shift track 1
Top surface on.Bed die template 5 is fixed on the top surface of support beam 21, according to template segmental length, can be arranged below bed die template
The assembly parts of more set bearing beams 2, limit assembly 3 and running gear 4.
As shown in figure 5, the two sides of 21 beam body of support beam are respectively connected with connecting rib 211.
As shown in fig. 6, the two sides of 22 beam body of attachment beam are respectively connected with stiffener plate, the both ends of beam body are also connected with end connection
Plate 221.
From figure 3, it can be seen that limit assembly 3 includes limiting clamping plate 31, limited block 32 and caging bolt 33, limited block 32
Outer angle between the upper flange and web of vertical shift track 1, caging bolt 33 is tilted upward to be inserted after limit clamping plate 31
Enter and is limited in limited block 32.
It can be seen that in conjunction with Fig. 3 and Fig. 6 and lead between the upper end of limit clamping plate 31 and the end connecting plate 221 of attachment beam 22
Bolt and nut connection fastening is crossed, lower end is interior folded plate.In order to enhance the intensity of limit clamping plate 31, top setting on the outside is reinforced
Muscle 311.In order to guarantee the intensity after caging bolt 33 connects, the end of reinforcing rib is corresponded on the outside of the interior folded plate of limit clamping plate 31
Place's welding high nut 312, caging bolt 33 are then passed through the interior folded plate for limiting clamping plate after being first screwed into high nut 312.
It can be seen that fluted on the outside inclined-plane of limited block 32, the insertion of caging bolt 33 groove in conjunction with Fig. 3 and Fig. 8
In.It is bonded on the downside of the inside of the present embodiment limited block 32 and the web of vertical shift track 1 and top flange, the innermost insert of limited block 32
There is permanent magnet 321, limited block 32 is adsorbed on vertical shift track 1 by permanent magnet 321.
Can be seen that running gear 4 in conjunction with Fig. 2, Fig. 4 and Fig. 9 includes idler wheel 41, supporting leg 42 and driving device.This implementation
The supporting leg 42 of example has two groups four, and each supporting leg is the L-type body that angle is greater than 90 degree, and there are two hinges arranged up and down in long-armed upper end
Hole is connect, the upper end of every group of two supporting legs is hinged by upper lower bearing pin with the connecting rib 211 of 3 web end side of support beam respectively
After form herringbone structure, supporting leg is only rotated around upper pin.An idler wheel 41 is connected separately at the galianconism of each supporting leg 42.
Two ipsilateral idler wheels of 21 web of support beam are installed in same root shaft 43, and shaft 43 and each supporting leg junction are respectively provided with axis
It holds, mounting hole elastic conjunction or welding on bearing and supporting leg.Other embodiments can also only be arranged two according to the actual situation
Supporting leg.
As shown in Fig. 2, the driving device setting of the present embodiment is a set of, including stepper motor 44, drive sprocket 45, driven chain
Wheel 46 and chain 47, stepper motor 44 are installed between the supporting leg 42 of two sides.Drive sprocket is connected to the output shaft of stepper motor

It can also be V belt translation component or gear-driven assembly.
As shown in Figure 10, when beam body 6 pours, this system is in loaded state.When the state, by each supporting leg upper end and support
Lower bearing pin between beam is extracted, and each supporting leg be freely rotated can around upper pin.Bearing beam is located on vertical shift track, and load passes through
Vertical shift track and pedestal reach ground.Meanwhile the caging bolt of limit assembly holds out against limited block, vertical force component and transverse component
The upper surface and side for making limited block are pressed respectively against on the upper flange and web of vertical shift track, limit bed die transverse direction and vertical position
It moves, and its frictional force generated then limits the length travel of bed die, realizes multiple degrees of freedom limit, so that guarantee beam body pours matter
Amount.
When bed die template need longitudinally adjusted position when, unclamp caging bolt, due to bearing beam connection soffit with
Without being fixedly connected between vertical shift track, bearing beam is jacked to certain height using jack class jacking apparatus, supporting leg is in weight
Lower bearing pin is installed when being swung down to idler wheel contact vertical shift rail top face under power effect, leg location is fixed, then tears open
Except jacking apparatus.Since bearing beam has disengaged from vertical shift track, so the load of bed die template reaches running gear.Control stepping
The rotation of motor work belt turn axis, vertically moves running gear along the movement of vertical shift track with bed die template by idler wheel,
It realizes from traveling.From when traveling, limit assembly plays cross spacing, can prevent traveling from deviateing.
