In a kind of, climb arm tower crane in climb girder steel transporting device
The utility model relates to transporting device, climb in specifically a kind of arm tower crane in climb girder steel transporting device.
Tower crane is as most important vertical transport instrument in Construction of High-rise, what the vertical transport instrument in high-building construction the most often adopted is outer attached self-standing crane, but after exceeding 200m, depth of building because being subject to attached tower crane outside the restriction of standard section of tower crane cannot meet construction needs, considers group impact of tower operation because Core Walls Structure is less simultaneously.Therefore change in Super High construction and climb arm tower crane in employing, the arm tower crane of inside creeping is a kind of tower machine being arranged in interior of building elevator or stair case, can progressively upwards climb with construction progress. except special inside-climbing tower crane, general self-elevating tower crane increases climbing system one, and sets up girder steel.The arm tower crane of inside creeping needs three cover load-bearing girder steels in work progress, and the most lower one girder steel be for load-bearing, and up one girder steel is for the impact of fixed tower and offset by the level of power.Go up most turnover while together needing again to climb and use below building concrete masterplate is constructed tower crane, by the joint that climbs, jacking cylinder, climb band and change step successively to reach the object that tower crane whole is climbed.
Because the most important condition of tower crane climbing is complete for going up most one steel girder erection, therefore that the girder steel work of having bad luck seems is very important.Because the high-level structure construction period is more and more tighter, traditional method is to utilize an other swing arm tower crane to self having bad luck the work of girder steel simultaneously, causes in two problems that tower crane cannot be constructed of tower crane construction simultaneously, has restricted the duration.Also there is minority building site not tight because of the duration, the on-the-spot situation that a tower crane is only installed simultaneously.Above two kinds of situations all wish that inside-climbing tower crane can self have bad luck girder steel in a hurry, but due to the self-defect of swing arm tower crane, even if the large arm elevation angle reaches 87 degree left and right, steel rope vertically puts down still and exceedes about 4-5m from tower body center, and in climb girder steel owing to will bearing the needs of the weight of tower crane own, conventionally heavier, inside climb girder steel and must be close to standard knot and install and place.
