Abstract

Изобретение относитс к подъемно-транспортному машиностроению, а именно к способам сборки пролетных секционных балок кранов, преимущественно с посадочными местами под опоры крана. Цель изобретени - снижение трудоемкости. Дл этого на установочную плоскость Б подают секцию 2, приваривают подставки 15, перемещают секцию до упора 13 и до упоров, определ ющих вертикальную плоскость. К секции 1 приваривают подставки 15 и перемещают ее на плоскости Б до упора фланцем 7 в торце секции 2, а затем до упоров, определ ющих вертикальную плоскость. Приваривают фланец 7 к секции 2. Устанавливают на секцию 2 проушину 10, располага ее ось на рассто нии A от упора 13, а оси посадочных мест 12 под опоры крана параллельно плоскости Б и вертикальной плоскости и закрепл ют проушину 10. Затем секции 1 и 2 разбирают по стыку фланцев 6 и 7, секцию 1 убирают, а на ее место перемещают секцию 2 и подают секцию 3 на место секции 2 и т.д. 6 ил.The invention relates to a lifting and transport machinery, and in particular to methods for assembling span sectional beam cranes, mainly with seating for crane supports. The purpose of the invention is to reduce the complexity. To do this, section 2 is fed to the installation plane B, the supports 15 are welded, the section is moved to the stop 13 and to the stops defining the vertical plane. Stands 15 are welded to section 1 and moved on the plane B up to the stop by a flange 7 at the end of section 2, and then up to the stops defining the vertical plane. Flange 7 is welded to section 2. The eyelet 10 is installed on section 2, its axis is located at a distance A from the stop 13, and the axes of the seats 12 for the crane supports are parallel to plane B and the vertical plane and the eyelet 10 is fixed. Then sections 1 and 2 disassemble the junction of the flanges 6 and 7, section 1 is removed, and in its place section 2 is moved and section 3 is fed to section 2, and so on. 6 Il.

Claim

A method of installing support elements on sections of the crane span, according to which the n-th section of the rail is mounted on the mounting support on the construction, construction support, the n + 1 section is fed and installed on the construction support, connect the section flanges to each other another and fix the sections on the rails of the rails, characterized in that, in order to reduce the complexity, before moving the n + 1st section to the mounting pad, they are mounted on its end, the fifth flange is the outer flange of the n + 1st section with the end face n sections and on sections with overlapping joints install the rails, fix them on the site until the junction of the sections, then disconnect the section flanges and the nth section is removed from the installation site, move the n + 1st section to the place of the nth section and place the n + 2nd section on the site pre-installed on its end face of figure 2
