Abstract
The utility model relates to a piston shoe for pushing a cantilever bridge box girder. The piston shoe comprises a piston shoe body arranged on a sliding track. The piston shoe is characterized in that an adjusting cushion block used for adjusting the bridge type camber is arranged on the upper portion of the piston shoe body, a thrust plate and a lateral limiting plate for preventing a bridge body from longitudinally and transversely fleeing relative to the bridge body during pushing respectively are arranged on the front face and the lateral face of the piston shoe body respectively, a track limiting plate used for limiting the piston shoe body from offsetting relative to the sliding track is arranged on the lower portion of the piston shoe body, and a lug plate and a connecting hinge shaft which are connected with a pushing oil cylinder are arranged on the back lateral face of the piston shoe body. The piston shoe has the advantages that the structure is adopted, the transverse stability of a steel bridge is guaranteed, the bridge type elevation and the camber are adjustable, meanwhile, the piston shoe is effectively prevented from fleeing in the pushing process, the steel bridge cannot offset in the sliding process accordingly, and smooth implementation of the pushing construction is guaranteed.
Description
Technical field
The utility model relates to a kind of bridge box girder construction equipment, and particularly a kind of cantilever bridge case back pushes away and uses piston shoes.
Background technology
The mounting methods that set up falsework that adopt when the existing bridge across obstructions such as intersection or railways is installed more, across railway bridge because train will normally move, just can not install by support jig, can only adopt sliding method to install, common sliding method is all to adopt tractive method to install, and because bridge box section changes, traction point is difficult to arrange, rope for traction is long will cause rope downwarp, and during tractive, walking is not steady.Tractive method will arrange slip support abutment on several interim detached piers, and bridge case beam slides forward by the slide plate constantly importing and exporting on slip support abutment, and slide plate will lean on artificial constantly feeding, the problem of this mount scheme have following some:
1. tractive force cannot be offset voluntarily, will to horizontal force 2. bridge case beam base plates on interim independent support and bridge pier, on the slip support abutment of level altitude, slide along bridge, bridge bottom surface is on-plane surface owing to there being camber, slides slip support abutment in process and can not adapt to the bridge bottom surface that absolute altitude constantly changes.
3. slip support abutment cannot, to pontic lateral Displacement, need additional side direction jack correction.
4. the loss of slide plate is large, and recycling rate of waterused is low, needs artificial constantly feeding.
5. slip support abutment location arrangements is dumb, can not adapt to the installation requirement of variable cross-section bridge case beam.
Above problem causes the speed of slippage slow, and operating expenses is large, bridge type low precision, and bridge case beam is easy deflection in slipping, so shuffle effect is undesirable.
Summary of the invention
The purpose of this utility model is to provide a kind of piston shoes play in pushing tow process that prevented, guarantees
The lateral stability of steel bridge and make bridge type absolute altitude and camber adjustable, and the cantilever bridge case back that can reuse pushes away and uses piston shoes.
The purpose of this utility model is to realize like this.
Cantilever bridge case back of the present utility model pushes away with piston shoes, comprise the piston shoes body arranging on sliding rail, it is characterized in that being provided for adjusting on described piston shoes body top the adjustment cushion block of bridge type camber, thrust plate and the side limiting plate of the relative piston shoes vertical and horizontal of pontic play while being provided for preventing pushing tow are set respectively with side before described piston shoes body, in described piston shoes body bottom, be provided for limiting the railway limit plate of the relative sliding rail skew of piston shoes body, at the trailing flank of piston shoes body, be provided with the otic placode that is connected with pipe bending cylinder and be connected bearing pin.
The utility model has the advantages that:
The utility model, owing to having adopted said structure, has guaranteed the lateral stability of steel bridge and has made bridge
Type absolute altitude and camber are adjustable, have simultaneously also effectively prevented piston shoes play in pushing tow process, thereby make in steel bridge slipping not deflection, guarantee carrying out smoothly of incremental launching construction.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, cantilever bridge case back of the present utility model pushes away with piston shoes, comprise that the piston shoes body 1 arranging on sliding rail is characterized in that being provided for adjusting on described piston shoes body 1 top the adjustment cushion block 3 of bridge type camber, guaranteed the lateral stability of steel bridge and make bridge type absolute altitude and camber adjustable, at described piston shoes body 1, thrust plate 2 and the side limiting plate 4 of the relative piston shoes vertical and horizontal of pontic play while being provided for preventing pushing tow are set respectively above with side, in described piston shoes body 1 bottom, be provided for limiting the railway limit plate 7 of relative sliding rail 6 skews of piston shoes body 1, and form end slipway, at the trailing flank of piston shoes body 1, be provided with the otic placode 9 that is connected with pipe bending cylinder and be connected bearing pin 10.Effectively prevented piston shoes play in pushing tow process, thereby made in steel bridge slipping not deflection, guarantee carrying out smoothly of incremental launching construction, number in the figure 5 be thrusting slip platform, and label 8 is to be placed in the bridge case beam on piston shoes.
