Abstract
Изобретение относитс к мостостроению , в частности к строительству или реконструкции однопролетных однопутных мостов с металлическими пролетными строени ми (фермами) на стро щихс или действующих транспортных магистрал х. Цель изобретени - сокращение материальных и трудовых затрат, упрощение монтажных работ, повышение производительности труда, сокращение продолжительности монтажных работ Устройство включает сборно-разборную передвижную раму 1, смонтированные на ней сборно-разборные башни 2, спаренные поверху грузовыми ригел ми 3, на которых установлен гидродомкраты 4, причем устройство снабжено установленными на грузовых ригел х 3 фиксаторами-ограничител ми 5 и направл ющими штангами 6. Внутри направл ющих штанг 6 смонтированы шарнирно опертые на головки штоков гидродомкратов 4 верхние подъемные балки 7, шарнирно объединенные штоками 8 е грузовыми, имеющими отверсти , лентами 9, пропущенными через грузовые ригели 3, в которых образованы отверсти 10 под штоки 8. Нижние концы с грузовых лент 9 шарнирно объединены с ниж- ними подъемными балками 11, расположен- tf ными вдоль пролета и пропущенными через -- нижние продольные балки 12, расположен- V- ные поперек пролета. 2 ил.сThe invention relates to bridge construction, in particular, to the construction or reconstruction of single-span single-track bridges with metal spans (trusses) on constructed or existing transport lines. The purpose of the invention is to reduce material and labor costs, simplify installation work, increase labor productivity, reduce the duration of installation work. The device includes a collapsible movable frame 1 mounted on it collapsible towers 2, paired on top of cargo transom 3, which are equipped with hydraulic jacks 4, the device being equipped with 3 locking clamps 5 and guide rods 6 mounted on the cargo gantries 6. Inside the guide rods 6 there are mounted hinged arms and the heads of the rods of the hydraulic jacks 4 upper lifting beams 7, pivotally connected by rods 8 e cargo, having openings, ribbons 9, passed through cargo girders 3, in which holes 10 are formed under the rods 8. lifting beams 11, located tf nymi along the flight and passed through - lower longitudinal beams 12, located V - across the span. 2 Figs
