Description

A kind of central drainage comb-tooth bridge expansion device
Technical field
The present invention 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 ponding contamination in use appears in bottom, affect the normal use of comb-tooth bridge expansion device; Further, adopt easy water container, rainwater can be made along the landing of bridge floor lower edge to 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.
Summary of the invention
Goal of the invention of the present invention is: the central drainage comb-type telescoping device providing the environmental protection again of a kind of cheap, compact conformation, effectively can overcome the deficiency of conventional telescopic device in draining.
The technical solution used in the present invention 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 is flexibly connected with fixed fingers plate, the other end and transverse joint plate one end hinged, the described transverse joint plate other end is hinged on beam body B, adhesive tape A is adopted to seal between described beam body B and transverse joint plate, described transverse joint plate and movable comb tooth plate hinged place adopt adhesive tape B to seal, watertight shutter is provided with between the end of described transverse joint plate and beam body A, central drainage region is formed between fixed head and watertight shutter, both sides, central drainage region are provided with central drainage pipe.
As preferred embodiment, described transverse joint plate, by can the sliding bearing base of longitudinal sliding motion bottom it and beam body A end realize being slidably connected, is achieved a fixed connection by fixed bearing base and beam body B end.By arranging sliding bearing base and fixed bearing base below transverse joint plate, enable transverse joint plate bear length travel, and be unlikely to rigid damage occurs.
As preferred embodiment, be provided with some pieces of transverse joint plates along bridge lateral, with adhesive tape C sealing between each piece.
As preferred embodiment, high in the middle of described central drainage region, both sides are low, and central drainage pipe is positioned at both sides, central drainage region lowest part.Sewage and foreign material, under this discrepancy in elevation, all can flow in central drainage pipe and discharge, can not residue in central drainage region.
As preferred embodiment, at central drainage sections bottom, beam body A upper surface lays corrosion resistant plate.Corrosion resistant plate can protect beam body A not to be etched, and extends the application life of beam body A.When corrosion resistant plate can not continue to use, change and also facilitate.
As preferred embodiment, hinged by two linkages between described movable comb tooth plate and transverse joint plate.
As the further improvement to preferred embodiment described in the last period, by pinned connection between two connecting rods in described two linkages, bearing pin length is greater than the overall width of two connecting rods, and two connecting rods axial relative displacement can occur on bearing pin.This kind two linkage, effectively can clear up the impact that bridge three-dimensional motion produces the displacement of movable comb tooth plate.
In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows: effective sealing can be played, prevent rainwater and foreign material from entering connecting sewing between each beam body, rainwater and foreign material are made to flow into central drainage region along the gap of fixed fingers plate and movable comb tooth plate, then discharge from central drainage pipe, ensure that whole stretching device draining is smooth and easy, environmental protection is clean.
