Description

Изобретение относитс к подъемно- транспортному машиностроению, а именно к грузоподъемным установкам.FIELD OF THE INVENTION The invention relates to lifting and transport machinery, namely, lifting equipment.

Целъ изобретени - повышение надежности установки.The purpose of the invention is to increase the reliability of the installation.

На фиг.1 схематично изображена грузоподъемна установка, общий вид; на фиг.2 - то же, вид спереди. Грузоподъемна установка содержит пролетную балку 1, на которой установлена грузова тележка 2, выполненна .с полиспастом 3 механизма подъема,;одни из блоков 4 которого смонтированы на грузозахватном органе 5, и с опорными колесами 6, установленными с одной стороньг телеки 2. На балке 1 по обе стороны тележки 2 расположены грузовые каретки 7, соединенные с тележкой 2 посредством т г 8. Балансирна траверса 9 св зана концами с каретками 7. Под балкой 1 расположена опорна балка 10 параллельно ее поперечной оси и выполненной с обратным роликом 11 на конце. Тележка 2 со стороны 6 выполнена с несущей консолъю, а также с удерживающими катками 12, на тележке 2 смонтирован механизм 13 подъема. Траверса 9 расположенаFigure 1 schematically shows a lifting device, a general view; figure 2 - the same, front view. The lifting device contains a flying beam 1, on which the load trolley 2 is installed, is made with a hoist 3 hoist mechanisms, and one of the blocks 4 of which are mounted on a load gripping body 5, and with supporting wheels 6 mounted on one side of tele 2. On beam 1 On both sides of the trolley 2, freight carriages 7 are located, connected to the trolley 2 by means of t g 8. The balance yoke 9 is connected to the carriages 7 by its ends. Under the beam 1 there is a support beam 10 parallel to its transverse axis and made with a return roller 11 and the end. The trolley 2 from side 6 is made with a supporting bracket, as well as with retaining rollers 12, and a lifting mechanism 13 is mounted on the trolley 2. Traverse 9 is located

под консолью теледки 2, св зана Концами с каретками 7 шарнирно и жестко соединена в средней части с концом балки 10. Другие блоки 4 подвешены на балке lO под колесамиunder the cantilever 2 console, connected with the ends with the carriages 7 is hinged and rigidly connected in the middle part with the end of the beam 10. Other blocks 4 are suspended on the beam lO under the wheels

6, а ролик 11 соединен с балкой 1.6, and the roller 11 is connected to the beam 1.

Грузоподъемна установка работает следуюпцим образом.Lifting equipment works in the following way.

Нагрузка от веса груза распредел етс вдоль пролетной балки 1,The load from the weight of the load is distributed along the span beam 1,

при этом одна часть нагрузки передаетс через тележку 2, а друга - через каретки 7. За счет распределени нагрузки вдоль балки 1 увеличиваетс грузоподъемность установки.however, one part of the load is transmitted through the trolley 2, and the other through the carriages 7. Due to the distribution of the load along the beam 1, the load capacity of the installation increases.

Благодар расположению грузозахватного органа 5 и его блоков 4 под колесами 6, а также ролику 11 снижаютс в целом усили на колеса 6 и скручивающие усили , действуквдиеDue to the location of the load-gripping body 5 and its blocks 4 under the wheels 6, as well as the roller 11, the forces on the wheels 6 and the torsion forces are reduced as a whole,
