Specific embodiment
It will be seen from figure 1 that this automatic longitudinal-moving device of box girder inner formwork disclosed in the present embodiment, is installed on beam making bench
Between ZLTZ and internal model storage pedestal CFTZ.
Can be seen that the present apparatus mainly in conjunction with Fig. 1 to Fig. 6 and include conveyor track 1, vertical shift bracket 2 and pre-buried mounting base 3,
Driving device 4, anti-idler wheel 5.Conveyor track 1 is fixed on the width direction median plane of internal mold main girder bottom surface, i.e. conveyor track edge
Beam length direction arrangement.Pre-buried mounting base 3 is set to the ground between beam making bench ZLTZ and internal model storage pedestal CFTZ, vertical shift branch
Frame 2 by pre-buried mounting base 3, detachably fix by installation.Vertical shift bracket 2 is rectangle frame frame body, the width direction at its longitudinal both ends
Driving device 4, longitudinal both ends four corners pair of vertical shift bracket are installed by the support frame 21 being arranged symmetrically respectively on median plane
Claim installation can rotation anti-idler wheel 5.
Conveyor track 1 uses pin tooth rack gear or chain, and the present embodiment uses pin tooth rack gear, correspondingly, the present embodiment drives
The driving wheel 41 of dynamic device uses gear.
The bottom of vertical shift bracket 2 is provided with the supporting leg 22 of adjustment height.Four at vertical shift bracket longitudinal direction both ends of supporting leg 22
Corner is symmetrical arranged four, is screw thread lifting structure, nut 221 and vertical adjustment spiral shell including being welded on 2 bottom of vertical shift bracket
Bar 222, the bottom of vertical adjustment screw rod 222 offer the pin hole of horizontal direction, and the lower end of vertical adjustment screw rod is the ball of evagination
Face.
Pre-buried mounting base 3 includes bottom plate 31, vertical plate 32, cushion block 33 and connecting plate 34, and bottom plate 31 is rectangular slab, and cushion block 33 is solid
Due to the middle position of bottom plate 31, connecting plate 34 is symmetrically rotatably articulated with the length of cushion block 33 by hinged ear mount and pin shaft
Direction two sides are spent, the top surface of cushion block 33 is without departing from ground.When connecting plate fell, pass through vertical plate 32 of floor length direction two sides
Support, after connecting plate fell, upper surface is concordant with ground.The present embodiment corresponds to cushion block 33 in the length direction two sides of bottom plate 31 respectively
Both ends setting vertical plate 32 support connecting plate 34.
Certain other embodiments can also use vertical plate and the isometric setting of bottom plate, hinge of the vertical plate in corresponding cushion block and connecting plate
It connects and opens up groove at position, in order to which the hinged installation of connecting plate and cushion block operates.
The center position of cushion block 33 has and the matched interior concave spherical surface 331 of convex spherical outside 222 lower end of vertical adjustment screw rod.Even
The pin hole location corresponded on vertical adjustment screw rod 222 on fishplate bar 34 has corresponding circular hole.
When pre-buried mounting base 3 is fixed on the ground, it is welded on the built-in fitting of ground by bottom plate 31, while guaranteeing connecting plate
34 when falling, and upper surface is concordant with ground.That is, pre-buried mounting base 3 is not installing preceding top surface and ground with vertical shift bracket 2
Concordantly, the passage of beam field device is not influenced.
The position of pre-buried mounting base 3 and 22 position of supporting leg of vertical shift bracket 2 are corresponding, when vertical shift bracket is installed, supporting leg
222 lower end of vertical adjustment screw rod is placed in the interior concave spherical surface at 33 center of cushion block, then overturns two connecting plates of pre-buried mounting base
Uprightly, two connecting plates 34 lock vertical shift bracket 2 by pin shaft and vertical adjustment screw rod lateral connection.
By mating spherical surfaces between vertical adjustment screw rod 222 and cushion block 33, more conducively the positioning of vertical adjustment screw rod 222 and
Guarantee stability when vertical shift bracket 2 works.
The lower section of vertical shift bracket 2 is also set up there are four universal travelling wheel 23.When vertical shift bracket 2 after hours, be adjusted
The height of vertical adjustment screw rod reduces vertical shift bracket 2, and universal travelling wheel 23 drops down onto walking on ground and is moved to vertical shift bracket 2
Storage position.
When vertical shift bracket 2 designs, crucial place is that the longitudinal direction between the driving wheel 41 of its both ends driving device 4 need to be made
Center is greater than the difference (as shown in Figure 1) of internal model vertical shift primary distance L and conveyor track length A away from B, to guarantee that internal model is round-trip
There is a driving wheel to engage when vertical shift with conveyor track always.In this way regardless of internal model needs which past direction movement real at any time
It is existing.That is, this is to guarantee that a vertical shift bracket can be realized internal model and store between pedestal back and forth in beam making bench and internal model
The key point of vertical shift.
It usually has been arranged symmetrically beam making bench in the two sides of internal model lodging bench seat, internal model storage pedestal is merely illustrated in Fig. 1
The beam making bench of side, that is to say, that pre-buried mounting base is respectively provided in the two sides of internal model lodging bench seat, by internal model vertical shift to side
Beam making bench on carry out prefabricated box -beam when, vertical shift bracket can be removed to the pre-buried peace for being installed to the other side from pre-buried mounting base
It fills on seat, the prefabricated of box beam will be carried out on the beam making bench of internal model vertical shift to the other side.
In order to improve the degree of automation of the present apparatus, limit is installed respectively at a pair of of Angle Position at vertical shift bracket both ends
Switch installs block in internal model end of main beam, and when internal model vertical shift, the block of end and contact, that is, internal model of limit switch are
In place, driving device is automatically stopped work for vertical shift.
In order to avoid vertical shift bracket is covering the internal model vertical shift direction occurred when internal models are used in turn by direction transformation for more
A change-over switch is arranged on vertical shift bracket to control the traffic direction of driving device, change-over switch instruction in the problem of going to the wrong way
Which side is just walked toward which side after internal model starting.
To be detachably connected between the vertical shift bracket and pre-buried mounting base of the present apparatus, and box beam is prefabricated on beam making bench
Time at least needs four days, and internal model vertical shift was once only needed using vertical shift bracket a few minutes, so the vertical shift bracket of the present apparatus
It is used in turn for covering internal model more, need to only be stored in beam making bench and internal model and pre-buried mounting base is set between pedestal, and pre-buried peace
It is concordant with ground when not in use to fill seat, nor affects on the passage of other equipment, very little is changed to the original construction environment in beam field,
The prefabricated efficiency that box beam can be improved, also significantly saves construction cost, the requirement for meeting green construction and economizing on resources.
In addition, vertical shift bracket can be easily moved at position to be installed by the universal wheel of its bottom, with the prior art
Realize that internal model being used in turn between multiple beam making bench is compared by hoist engine, not only portable construction, flexible operation, and
Without substantially increasing the stability and safety of internal model vertical shift process by rope traction.It avoids in work progress
Security risk.
