Изобретение относится к машиностроению, в частности к устройствам для сборки и разборки крепежных деталей фланцевых соединений сосудов давления, например главных разъемов химических и атомных реакторов, парогенераторов и тому подобного оборудования. Целью изобретения является упрощение конструкции и, следовательно, повышение надежности работы устройства. Цель достигается тем, что в устройстве для сборки и разборки крепежных деталей фланцевых соединений сосудов давления, содержащих установленные на общей опоре и объединенные гидравлически домкраты, каждый из которых состоит из цилиндра и поршней, в свою очередь каждый цилиндр снабжен упорами для поршней, причем ход поршня до упора больше его рабочего хода. Для уменьшения напряжений в стенках цилиндров ходы последовательно расположенных поршней до соответствующих упоров выполнены увеличивающимися в направлении перемещения поршней. 1 с. 1 з. п. ф-лы, 1 ил.The invention relates to mechanical engineering, in particular to devices for assembling and disassembling fasteners for flanged connections of pressure vessels, for example, the main connectors of chemical and atomic reactors, steam generators and similar equipment. The aim of the invention is to simplify the design and, consequently, increase the reliability of the device. The goal is achieved by the fact that in a device for assembling and disassembling fasteners for flanged connections of pressure vessels containing hydraulically connected jacks, each of which consists of a cylinder and pistons, each cylinder is provided with stops for pistons, until it stops more than its working stroke. To reduce the stresses in the cylinder walls, the strokes of the consecutive pistons to the corresponding stops are made increasing in the direction of movement of the pistons. 1 sec. 1 h. item f-ly, 1 ill.
