Device facilitating rapid installation of steel truss girder bridge support

The utility model discloses a device convenient for rapid installation of a steel truss girder bridge support, which is installed at the positions of a steel truss girder bridge cover beam and a piercap (platform cap) and comprises a slide way, a longitudinal beam, a transverse stiffening beam and a lower support frame mechanism, the slide way is fixed at the upper part of the longitudinal beam,and the top surface of the slide way is flush with a support cushion stone; the two ends of the longitudinal beam are erected on pier caps (platform caps), and the middle of the longitudinal beam is connected with the lower supporting frame. The device for quickly mounting the steel truss girder bridge support can be used as an auxiliary tool for mounting a large-tonnage support in the construction, maintenance and reinforcement of the steel truss girder bridge, overcomes the problem of insufficient space of a support mounting working surface, ensures the mounting precision of the support, islow in manufacturing cost,
