Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-3, a safety support bracket for bridge construction comprises a workbench 1 arranged along the left-right direction, and a supporting plate 2 arranged along the vertical direction; the lower end of the supporting plate 2 is fixedly matched with the left end of the workbench 1; the front side and the rear side of the supporting plate 2, the front side and the rear side of the workbench 1 and the right end of the workbench 1 are all fixed with a protection plate 3; a construction adjusting device is arranged on the right side of the supporting plate 2; the left side of the supporting plate 2, the middle part of the lower side of the workbench 1 and the right part of the lower side of the workbench 1 are all fixed with mounting blocks 4; the lower ends of the mounting blocks 4 are fixed with scaffolds 5; a load stabilizing device is arranged between every two adjacent scaffolds 5; a ladder stand 6 is arranged in front of the workbench 1; a positioning hook 7 is fixed on the rear side of the upper end of the ladder stand 6; the positioning hooks 7 correspond to the protection plates 3 on the work table 1.

The construction adjusting device comprises an escalator 8 arranged at the front side of the supporting plate 2 and a plurality of supporting pedals 9 uniformly distributed at the rear side of the supporting plate 2 from top to bottom; the supporting pedal 9 is arranged along the vertical direction; the lower end of the supporting pedal 9 is hinged with the right side of the supporting plate 2; a plurality of stop blocks 10 are arranged below each supporting pedal 9; the stoppers 10 are distributed along the front and rear direction; the left ends of the stop blocks 10 are fixed with the right side of the supporting plate 2; the lower part of the front side of the supporting pedal 9 is provided with a jack 11 along the front-back direction; a strut 12 is arranged in front of the lower part of each supporting pedal 9; the support post 12 is fixed on the supporting plate 2; the pillars 12 are arranged in the left-right direction; a positioning bolt 13 is connected to the pillar 12 through threads; the positioning bolts 13 are correspondingly inserted into the insertion holes 11 one by one.
