Description

Technical Field:

[0001] The utility model belongs to the technical field of bridge construction equipment design, especially the hanging basket design technology in the cantilever beam construction of bridges, and specifically relates to a hanging basket rear anchor downward pressure reaction frame device. Background Art:

[0002] In road construction, the proportion of bridges is also on the rise. The cantilever sections of long-span bridges generally adopt hanging basket construction. For the traditional hanging basket rear anchor downward pressure, four hand-operated hydraulic core-piercing jacks are required. The construction speed is slow. At the same time, for the rear anchor tie rods made of precision rolled threaded steel, the shear resistance is poor. When using the hand-operated hydraulic core-piercing jacks, the jacking speeds of the two hydraulic core-piercing jacks are often different, resulting in the precision rolled threaded steel being bent, greatly weakening its mechanical properties. Moreover, the lack of edge protection for the hanging basket rear anchor also poses certain potential safety hazards to the operators. Summary of the Invention:
