Description
Известны подъемные устройства, преимущественно дл монтажа пролетных строений мостов (ферм весом 400-500 т), состо щие из опорной конструкции с направл ющими блоками, захватного органа, св занного гибким элементом с противовесом в виде заполн емого водой бака, систем подачи воды в бак и регулировани скорости подъема груза и опускани захвата.Lifting devices are known, primarily for mounting bridge spans (trusses weighing 400-500 tons), consisting of a support structure with guide blocks, a gripping member connected by a flexible element with a counterweight in the form of a tank filled with water, water supply systems to the tank and adjusting the speed of lifting and lowering the grip.
Однако известные устройства имеют существенные недостатки: мёдленный подъем груза и опускани порожнего захватного органа.However, the known devices have significant drawbacks: the slow lifting of the load and the lowering of the empty gripping body.
Отличительной особенностью описываемого подъемного усгройства вл етс то, что дл обеспечени заданной скорости подъема груза вне зависимости от изменени разности весов груза и противовеса система регулировани скорости выполнена в виде установленного на онорно:-: конструкции дополнительного подъемного механизма, включающего i; себ приводную лебедку и канатный нолиспаст, воспринил1ающий част;, веса поднимаемого груза.A distinctive feature of the described lifting device is that in order to provide a given speed of lifting the load, regardless of the change in the difference between the weights of the load and the counterweight, the speed control system is designed as installed: -: the design of the additional lifting mechanism, including i; the drive winch and the cable nolispast, which receives the part ;, the weight of the lifted load.
. На фиг. 1 изображено описываемое подъемное устройство, в общем виде; на фиг. 2 - кинематическа схема устройства.. FIG. 1 depicts the described lifting device, in general; in fig. 2 - kinematic diagram of the device.
Подъемное устройство в основном состоит из следующих узлов: опорной фермы (башни) 1 с направл ющими блоками 2 дл несущих канатов 3, противовесов 4 с системой 5 дл их балластировки и подъем ных лебедок 6 с полиспастами 7. Противовесы устройства выполнены и виде емкостей-баков.The lifting device mainly consists of the following components: support truss (tower) 1 with guide blocks 2 for supporting ropes 3, counterweights 4 with system 5 for ballasting them and lifting winches 6 with tackle 7. Counterbalances of the device are made in the form of tanks-tanks .
Подъем и погрузка т желовесных блоков пролетных строений 8 осу ществл етс лебедками со сравнительно малым т говым усилием и при малой кратности полиспастов.The lifting and loading of the hawkish blocks of the spans 8 is carried out by winches with a relatively low pulling force and with a small multiplicity of polyspasts.
Лебедками посредством полиспастов порожние противовесы пот,нимают в верхнее положение, строповочные приспособлени 9 закрепл Winches, by means of tackles, empty counterweights, sweat, put them in the upper position, slinging devices 9 secured
