Abstract

The invention discloses a self-climbing tower crane, which comprises a tower body (1), a hoisting arm (2) and a climbing mechanism, wherein the climbing mechanism comprises a main stressed supporting steel beam (4) and a steel structure climbing attached frame (5); the steel structure climbing attached frame (5) is fixedly connected on the main stressed supporting steel beam (4) and is provided with a jacking cylinder (8) and a supporting steel beam (9); and a tower body supporting tread (10) is arranged on a tower body (1), and the bottom of the tower body (1) is provided with a climbing base section (11). The self-climbing tower crane can climb upward along a constructed structure by using the constructed building structure as a support, meet the requirements of superhigh-rise and out-of-code tall buildings on vertical transportation at the whole construction height, contribute to construction efficiency, construction period reduction, steel conservation and energy conservation and create obvious economic and social benefits.

Description

technical field [0001] The invention relates to a tower crane for construction, in particular to a self-climbing tower crane. Background technique [0002] With China's economic development, urban construction is changing with each passing day, and a large number of super high-rise and over-limit high-rise buildings appear, which also put forward different individual requirements for the use of construction tower cranes. At present, the traditional attached tower crane is the most used on the construction site, but the height of this ordinary attached tower crane is limited, and the maximum allowable installation height is only 180 meters. This attached tower crane obviously cannot meet the use requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a self-climbing tower crane. The self-climbing tower crane only uses the height of the tower body of about 30 meters after the ordinary tower crane is refitted...
