Изобретение относитс к подъемнотранспортным механизмам и устройствам и предназначено дл применени при строительстве многопролетных промышленных зданий, оборудованных мостовы-ми кранами.The invention relates to lifting transport mechanisms and devices and is intended for use in the construction of multi-span industrial buildings equipped with bridge cranes.
Известен башенный кран, содержащий смонтированную на портале башню, стрелу, противовесную конеоль с контргрузом и трособлочный грузоподъемный механизм 1.The famous tower crane containing a tower mounted on the portal, boom, counterweight trunk with counter-load and cable-block lifting mechanism 1.
Недостатком известных башенных кранов на рельсовом ходу вл етс наличие специальных подкрановых путей , требующих установки и ухода в процессе эксплуатации.A disadvantage of the known rail-mounted tower cranes is the presence of special crane runways that require installation and maintenance during operation.
Специальные подкрановые пути ба ,шенных кранов вл ютс большой помехой при строительстве и реконструкции многопролетных зданий, например прокатных цехов, сталеплавильных корпусов и других, пролеты которых- насыщены сложными подземными и наземными, сооружени ми и оборудованием.The special crane runways of the basement cranes are a great hindrance to the construction and reconstruction of multi-span buildings, such as rolling shops, steel-smelting buildings and others, whose spans are full of complex underground and surface structures and equipment.
Кроме того, башенные краны почти исчерпали свои возможности по высоте подъема и глубине подачи груза, в то врем как высота зданий растет.In addition, the tower cranes are almost exhausted in their lifting height and depth of supply of cargo, while the height of buildings is growing.
Известен способ перестановки башенного крана на пролетное строение мостового крана в многопролетных промышленных здани х посредством полиспастной системы 1.There is a known method of rearranging a tower crane onto a span crane of a bridge crane in multi-span industrial buildings by means of a polyspast system 1.
Недостатком известного способа The disadvantage of this method
10 вл етс его сложность.10 is its complexity.
Цель изобретени - расширение функциональных возможностей крана путем перестановки его на пролетное строение мостового крана и упрощение спо15 соба монтажа и демонтажа крана.The purpose of the invention is to expand the functionality of the crane by rearranging it on the bridge crane span and simplifying the method of mounting and dismounting the crane.
Поставленна цель достигаетс тем, что.в устройстве портал выполнен составным из нижней и верхней частей, соединенных между собой крепежными The goal is achieved by the fact that in the device the portal is made of a composite of the lower and upper parts interconnected by fastening
20 элементами.20 elements.
