Abstract
Изобретение относитс к подъемп:- но-транспортному машиностроению. Целью изобретени вл етс расширение зоны обслуживани . Механизм поворота стрелового крана состоит из силового цилиндра 1, шатунов 2, поворотной колонны 3 и направл ющей 4. Шток силового цилиндра 1 соединен посредством пальца с шатунами 2 и составным роликом, которьй расположен в пазу направл ющей 4. Второй конец шатунов -2 соединен пальцем с кривошипом 8, который жестко прикреплен к поворотной колонне.-З. Корпус силового цилиндра 1 установлен шар- нирно на поворотном кронштейне 9, которьй смонтирован на оси стойки 11. Положение кронштейна 9 относительно стойки 11 устанавливаетс фиксатором 12. Работой цилиндра 1 достигаетс увеличение поворота колонны за счет изменени положени гидроцилиндра в 1или II положении. 4 ил. I О)The invention relates to a hoist: - but-transport machinery. The aim of the invention is to expand the service area. The mechanism of rotation of the boom crane consists of a power cylinder 1, connecting rods 2, a rotary column 3 and a guide 4. The rod of the power cylinder 1 is connected with a finger to the connecting rods 2 and an integral roller, which is located in the groove of the guide 4. The second end of the connecting rods -2 is connected with a finger with a crank 8, which is rigidly attached to the rotary column. -W. The body of the power cylinder 1 is hinged on the pivot bracket 9, which is mounted on the axis of the rack 11. The position of the bracket 9 relative to the rack 11 is fixed by the latch 12. By the operation of the cylinder 1, the rotation of the column is increased by changing the position of the hydraulic cylinder in the 1 or II position. 4 il. I O)
