(54) БАШЕННЫЙ КРАН ДЛЯ СТРОИТЕЛБНО-МОНТАЖНЫХ И БЕТОННБ1Х РАБОТ(54) TOWER CRANE FOR CONSTRUCTION AND INSTALLATION AND CONCRETE WORKS
1one
Изобретение относитс к подъемно-транспортному оборудованию, в частности к строительным башенным кранам, и может быть использовано при возведении промышленных и гражданских зданий и сооружений из монолитного железобетона.The invention relates to a lifting and transport equipment, in particular to building tower cranes, and can be used in the construction of industrial and civil buildings and structures of monolithic reinforced concrete.
Известен башенный кран дл строительно-монтажных и бетонных работ, содержгший башню, на оголовке которой смонтирована поворотна стрела, выполненна с консольной частью, несуш,ей противовес, бетоновод, установленный внутри башни вдоль ее продольной, оси, и бетонораспределительную стрелу 1.Known tower crane for construction and concrete works, containing a tower, on the top of which is mounted a swing arm, made with a cantilever part, floor, counterweight to it, a concrete pipe installed inside the tower along its longitudinal axis, and a concrete distribution boom 1.
Недостатком известного устройства вл етс значительна сложность его конструкции , вызванна необходимостью монтажа бетонораспределительной стрелы на башне крана.A disadvantage of the known device is the considerable complexity of its design, caused by the need to install a concrete distribution boom on a crane tower.
Цель изобретени - упрош.ение конструкции устройства за счет использовани бетонораспределительной стрелы в качестве противовеса.The purpose of the invention is to simplify the construction of the device by using the concrete distribution boom as a counterweight.
Указанна целЪ достигаетс тем, что бетонораспределительна стрела смонтирована на консольной части крана.This target is achieved by the fact that the concrete distribution boom is mounted on the cantilever part of the crane.
На фиг. 1 схематически изображен предлагаемый кран со сложенной бетонораспределительной стрелой, выполн юш,ей роль противовеса при работе поворотной грузовой стрелы, общий вид; на фиг. 2 - тоFIG. 1 shows a schematic representation of the proposed crane with a folded concrete distribution boom, fulfilled ush, its role as a counterweight to the operation of a swing boom, general view; in fig. 2 - then
же, с работающей бетонораспределительной стрелой, развернутое положение. however, with a working concrete distribution boom, an unfolded position.
Кран содержит неповоротную башню 1, закрепленную на ходовой раме 2, и оголовок 3 башни, несущий грузовую поворотную стрелу 4 с консольной частью 5, несущей противовес. Внутри башни 1, вдоль ее продольной оси, установлен бетоновод 6, нижний горизонтальный участок которого соединен с бетононасосом (не показан), а верхний, смонтированный на оголовке 3, The crane contains a fixed tower 1, mounted on the chassis frame 2, and the tip 3 of the tower, carrying cargo swing boom 4 with a cantilever part 5, carrying a counterweight. Inside the tower 1, along its longitudinal axis, there is a concrete pipeline 6, the lower horizontal section of which is connected to a concrete pump (not shown), and the upper one mounted on the tip 3,
15 закреплен на бетонораспределительной стреле 7, установленной на консольной части 5 стрелы 4, и соединен с вертикальным участком посредство.м вращающейс муфты (не показана), расположенной строго15 is fixed on the concrete distribution boom 7 mounted on the cantilever part 5 of the boom 4 and connected to the vertical section by means of a rotating coupling (not shown) located strictly
20 по продольной оси башни 1. На конце бетонораспределительной стрелы 7 смонтирован направл ющий хобот 8 дл подачи бетонной смеси непосредственно к месту укладки .20 along the longitudinal axis of the turret 1. At the end of the concrete distribution boom 7, a guide trunk 8 is mounted for feeding the concrete mixture directly to the installation site.
Работа крана заключаетс в следующем.The operation of the crane is as follows.
Выполнение подъемно-транспортных операций при проведении строительно-монтажных работ осуществл етс известным способом с помощью грузовой стрелы 4, поворотной в горизонтальной плоскости, при этом бетонораспределительна стрела 7 находитс в сложенном положении на консольной части 5 и выполн ет роль противовеса при работе с грузом стрелы 4.When performing construction and assembly operations, the lifting and transport operations are carried out in a known manner using a cargo boom 4, which is rotatable in a horizontal plane, while the concrete distribution boom 7 is in the folded position on the cantilever part 5 and acts as a counterweight when working with the boom load .
Дл выполнени бетонных работ бетонораспределитёльную стрелу 7 развертывают в рабочее положение. ПодводЯг хобот 8 стрелы 7 к месту укладки бетона путем поворота стрелы 4 в горизонтальной плоскости и осуществл ют передачу бетонной смеси, нагнетаемой бетононасосом по бетоноводу 6.For concrete work, the distribution boom 7 is deployed to its working position. The supply of the trunk 8 of the boom 7 to the place of laying concrete by turning the boom 4 in the horizontal plane and transferring the concrete mixture pumped by the concrete pump through the concrete pipe 6.
Использование предлагаемого изобретени позвол ет существенно упростить конструкцию крана за счет использовани бетонораспределительной стрелы вместо противовеса , сохранив при этом оптимальную грузовую характеристику крана, а такжеThe use of the invention allows to significantly simplify the design of the crane by using the concrete distribution boom instead of the counterweight, while maintaining the optimum cargo characteristics of the crane, as well as
повысить эффективность его использовани на стройплощадке по сравнению с обычными грузоподъемными кранами, работающими только в подъемно-транспортном режиме.to increase the efficiency of its use on the construction site in comparison with conventional lifting cranes, working only in the lifting-transport mode.
