Description
Technical field
The utility model relates to the stretching device technical field of bridge, particularly a kind of central drainage comb-tooth bridge expansion device.
Background technology
Traditional comb-tooth bridge expansion device does not generally design dewatering installation or adopts easy bottom water receiving bucket device, cause between the comb plate of comb-tooth bridge expansion device and the ponding contamination in use appears in bottom, affect the normal use of comb-tooth bridge expansion device; And, adopt easy water container, can make rainwater along the landing of bridge floor lower edge to the girder belly, make beam-ends and bearing corrosion, affect the normal use of bridge and bearing.
Therefore, for the existing behavior in service of comb-tooth bridge expansion device, need to carry out structural improvement to it, to overcome the defect of draining aspect.
The utility model content
Goal of the invention of the present utility model is: a kind of cheap, compact conformation central drainage comb-type telescoping device of environmental protection again is provided, can effectively overcomes the deficiency of traditional stretching device aspect draining.
The technical solution adopted in the utility model is such: a kind of central drainage comb-tooth bridge expansion device, comprise beam body A, fixed head, transverse joint plate, movable comb tooth plate and fixed fingers plate, described fixed fingers plate is bolted on fixed head, fixed head welds or is anchored on beam body A, described movable comb tooth plate one end and fixed fingers plate are flexibly connected, the other end and transverse joint plate one end are hinged, the described transverse joint plate other end is hinged on beam body B, adopt adhesive tape A sealing between described beam body B and transverse joint plate, described transverse joint plate and movable comb tooth plate hinged place adopt adhesive tape B sealing, be provided with watertight shutter between the end of described transverse joint plate and beam body A, form the central drainage zone between fixed head and watertight shutter, both sides, central drainage zone are provided with the central drainage pipe.
As optimal way, described transverse joint plate, by realizing being slidably connected in sliding bearing base and the beam body A end of its bottom longitudinal sliding motion, achieves a fixed connection by fixed bearing base and beam body B end.By sliding bearing base and fixed bearing base are set below transverse joint plate, make transverse joint plate can bear length travel, and be unlikely to occur rigidity, damage.
As optimal way, be provided with some transverse joint plates along bridge lateral, between each piece, with adhesive tape C, seal.
As optimal way, high in the middle of described central drainage zone, both sides are low, and the central drainage pipe is positioned at both sides, central drainage zone lowest part.Sewage and foreign material, under this discrepancy in elevation, can all flow in the central drainage pipe and discharge, and can not residue in the central drainage zone.
As optimal way, in bottom, central drainage zone, beam body A upper surface is laid corrosion resistant plate.Corrosion resistant plate can protect beam body A not to be etched, and has extended the application life of beam body A.When corrosion resistant plate can not continue to use, it is also convenient to change.
As optimal way, hinged by two linkages between described movable comb tooth plate and transverse joint plate.
As the further improvement to described optimal way the last period, between two connecting rods in described two linkages, by bearing pin, connect, bearing pin length is greater than the overall width of two connecting rods, and axial relative displacement can occur two connecting rods on bearing pin.This kind two linkages, can effectively clear up the impact that the bridge three-dimensional motion produces the displacement of movable comb tooth plate.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are: can play effective sealing, prevent that rainwater and foreign material from entering the connecting sewing between each beam body, make rainwater and foreign material flow into the central drainage zone along the gap of fixed fingers plate and movable comb tooth plate, then discharge from the central drainage pipe, guarantee that whole stretching device draining is smooth and easy, environmental protection is clean.
