Description
(5) ПРОЛЕТНАЯ БАЛКА КРАНА(5) CRANE FLIGHT BEAM
1one
Изобретение относитс к подъемнотранспортному машиностроению, в частности к пролетным балкам дл кранов мостового типа.The invention relates to lifting and transport engineering, in particular, span beams for bridge-type cranes.
Известна пролетна балка крана, имеюща замкнутое сечение, образованное боковыми листами, между верхними и нижними кромками которых закреплены по сные элементы, причем боковые листы св заны ребрами жесткости 1.A crane crane is known, having a closed section formed by side sheets, between which upper and lower edges are fixed transverse elements, the side sheets being connected by stiffening ribs 1.
Недостатком известной балки вл етс необходимость изготовлени боковых листов желобообразного профил , что требует специального оборудовани , а также необходимость изготовлени большого количества ребер жидкости.A disadvantage of the known beam is the need to manufacture the side sheets of the grooved profile, which requires special equipment, as well as the need to manufacture a large number of liquid fins.
Цель изобретени - упрощение конструкции и снижение трудоемкости изготовлени балки.The purpose of the invention is to simplify the construction and reduce the laboriousness of manufacturing the beam.
Цель достигаетс тем, что боковые листы и ребра образованы из частей цилиндрической трубы, образующие которых параллельны продольной оси балки.The goal is achieved by the fact that the side sheets and ribs are formed from parts of a cylindrical tube, which form parallel to the longitudinal axis of the beam.
Кроме того, с целью повышени .жесткости, ребра дополнительно св заны с по сными элементами.In addition, in order to increase the stiffness, the ribs are additionally connected with tension elements.
На фиг. 1 изображена пролетна балка, общий вид; на фиг. 2 - вариант пролетной балки при соединении по сных элементов с ребрами; на фиг. 3 - вариант пролетной балки FIG. 1 shows the span beam, general view; in fig. 2 - a variant of the passage beam when connecting the belt elements with the ribs; in fig. 3 - version of the flying beam
10 при соединении боковых листов с полкой по сного элемента.10 when connecting the side sheets with the shelf of the slit element.
Пролетна балка образована боко j аыми листами 1 и 2, между верхними и нижними кромками которых закреплены по сные элементы 3 и . Боковые листы 1 и 2 св заны ребрами жесткосТи 5 и 6. Боковые листы 1 и 2 и ребра жесткости 5 и 6 вл ютс част ми The span beam is formed by lateral sheets 1 and 2, between the upper and lower edges of which the fixed elements 3 and are fixed. The side sheets 1 and 2 are connected by stiffeners 5 and 6. The side sheets 1 and 2 and stiffeners 5 and 6 are parts
20 цилиндрической трубы.20 cylindrical tube.
На фиг. 2 и фиг. 3 ребра жесткости 5 и 6 св заны дополнительно с по сными элементами 3 и 4.FIG. 2 and FIG. The 3 stiffeners 5 and 6 are additionally connected to the rim elements 3 and 4.
