The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Half range opening-closing type moving workbench vehicle as shown in the figure, comprises job platform 1, it is characterized in that: also comprise the spandrel girder 3 of bridge floor flatcar 2 and " L " shape, job platform 1 is hinged by spandrel girder 3 and bridge floor flatcar 2; The rack winch 24 that the counterweight frame 23 that bridge floor flatcar 2 comprises truss 21, the running wheel 22 being connected with the bottom of truss 21, be connected with the sidewall of truss 21 is connected with the top with truss 21; Counterweight frame 23 is provided with balancing weight 25; Spandrel girder 3 is comprised of upper beam 31 and vertical spandrel girder 32; One end of upper beam 31 and truss 21 central upper portion are hinged, and the other end of upper beam 31 is connected with the steel ropes of rack winch 24; The two ends of vertical spandrel girder 32 are connected with job platform 1 with upper beam 31 respectively.
The course of work of the present utility model is as follows: the utility model can be used in the bridge maintenances such as the beam reinforcement, the application of beam body, bearing replacement of simply supported girder bridge.According to design drawing, in conjunction with field condition and construction speed arrangement, determine high pier across and waterbornely across carbon fiber reinforcement construction, adopt half range opening-closing type job platform to construct.According to Design of Construction Organization, unpowered load on job platform, dead load design load is 1KPa, mobile load design load is 3KPa.
1, first according to engineering design, platform distribution beam, platform spandrel girder, vertical spandrel girder 32, upper beam 31 are checked, counterweight is calculated;
2, equipment is assembled: it is assembled that this equipment divides two parts to carry out, be respectively bridge floor flatcar 2 and job platform 1(and comprise upper beam 31, vertical carrier bar 32 and job platform 1 part), on bridge floor by above-mentioned two parts are assembled complete after, fixedly bridge floor flatcar 2, utilize crane to install job platform 1 part.
