Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is the B-B sectional view of Fig. 1.
Fig. 4 is the monorail trolley in the utility model constitutes the frictional movement pair with its friction pulley and maintenance track schematic diagram.
The specific embodiment
Technical characterstic of the present utility model is easier to be understood in order to make, below with reference to accompanying drawing and in conjunction with the embodiments the technical solution of the utility model is done to describe in detail:
With reference to Fig. 1, Fig. 2, Fig. 3, packaged type hanger operating platform of the present utility model, comprise the truss chassis 11 that is welded with shaped steel, lateral symmetry is welded with two pairs of vertically connection rod members 4 of symmetry on the described truss chassis 11, be respectively arranged with between every pair of described connection rod member 4 and make its firm crosspiece 8, the upper end of each described connection rod member 4 arranges the monorail trolley 5 that can constitute kinematic pair with the maintenance track 3 that steel truss girder carries respectively, and described monorail trolley 5 is provided with jack 6.
Distance between two couples connection rod member 4 of lateral symmetry welding on the described truss chassis 11 equals the spacing of two the maintenance tracks 3 in bridge floor bottom under the steel truss girder.
In order to be applicable to the needs of bridge floor bottom construction under the multiple steel truss girder, length * wide specification that the utility model arranges described truss chassis 11 is 16.5m * 8m.
In order to prevent falling object from high altitude and convenient construction, the utility model has been laid checkered steel plate 1 at the end face on described truss chassis 11, and with itself and described truss chassis 11 firm welding.
In order to guarantee construction safety, the utility model also is provided with guardrail 10 around 11 end faces of described truss chassis.
