The invention discloses a tower crane supporting structure which comprises a base, a tower crane standard knot is connected to the upper portion of the base, the tower crane standard knot comprises stand columns vertically fixed to the four corners of the base and stand column tie bars distributed between the adjacent stand columns in a staggered mode, and first hydraulic jacks in one-to-one correspondence with the stand columns are arranged on the bottom face of the base. The four corners of the base are each movably connected with a supporting beam, an inclined supporting rod is arranged between each supporting beam and the corresponding stand column, a hydraulic pin inserting and pulling oil cylinder is arranged at the pin shaft connecting position of each supporting beam, an inserting and pulling head of each hydraulic pin inserting and pulling oil cylinder is connected with the corresponding pin shaft, and a second hydraulic jack is arranged at the end, away from the bottom frame, of each supporting beam. The first hydraulic jacks and the second hydraulic jacks are distributed in a cross shape. The large-tonnage hydraulic jacks are distributed between the base and the bottom surface, so that the base is stable, the height of the base can be finely adjusted, and the tower crane is convenient to load and unload.

    本发明公开了塔式起重机支撑结构,它包括一底座,所述底座上方连接塔吊标准节,所述塔吊标准节包括垂直固定于底座四角处的立柱和交错分布于相邻立柱之间的立柱拉筋,所述底座底面设有与立柱一一对应的第一液压千斤顶,所述底座四角处均活动连接一支撑梁,每个支撑梁与对应的立柱之间设有一斜撑杆,所述支撑梁在销轴连接所在位置设有一液压插拔销油缸,所述液压插拔销油缸的插拔头连接销轴,所述支撑梁远离底架一端设有第二液压千斤顶,所有第一液压千斤顶和第二液压千斤顶呈十字形分布。本发明其底座和底面之间分布有大吨位液压千斤顶,使得底座既稳定,又能进行高度微调,从而方便塔式起重机的装卸。
