The invention relates to the technical field of tower cranes, in particular to an adjustable leveling conversion joint of a tower crane, which comprises a support frame, an upper support leg, a lower support leg and a base plate. The device is reasonable and compact in structure, and when the tower crane pre-embedded supporting leg is flat after being poured or the inclination of the tower crane exceeds a standard value due to differential settlement after the tower crane is installed, the levelness of the supporting frame and the upper supporting leg can be adjusted by changing the number of the base plates or/and the thickness of the base plates, so that the supporting leg can be conveniently adjusted. The inclination degree of the tower crane meets the standard after the tower crane is installed, potential safety hazards during use of the tower crane are reduced, the levelness of the supporting frame and the upper supporting leg is adjusted by changing the number of the base plates or/and the thickness of the base plates, and the adjustment of the upper supporting leg can meet the error phenomenon of the pre-embedded supporting leg; under the condition that an existing foundation is uneven in level, leveling installation and use can be directly conducted, and the advantages of being easy, convenient and fast to use, efficient and low in cost are achieved.

    本申请涉及塔式起重机技术领域,是塔式起重机可调节式调平转换节,包括支撑架、上支腿、下支腿和垫板。本申请结构合理而紧凑,在塔式起重机预埋支腿浇筑后存在平的现象,或者塔式起重机安装完毕后发生不均匀沉降导致塔式起重机的倾斜度超出标准值时,可以通过改变垫板的数量或/和垫板的厚度调节支撑架和上支腿的水平度,使得塔式起重机安装完毕后倾斜度符合标准,降低塔式起重机使用时的安全隐患,通过改变垫板的数量或/和垫板的厚度调节支撑架和上支腿的水平,能够使得上支腿的调节满足预埋支腿出现的误差现象,在现有基础水平出现不平的情况下,可直接进行调平安装使用,具有使用简单、便捷、高效、成本低的优点。
