The invention provides a tower crane adjustable bracket, and relates to the technical field of brackets. The adjustable bracket comprises a first A-shaped frame and a second A-shaped frame, the outersurface of the first A-shaped frame is rotatably connected with a first block through a bolt, a limiting groove is formed in the side wall of one side of the outer surface of the second A-shaped frame, a second block is slidably connected to the inner wall of the limiting groove, mounting columns are fixedly mounted at the top of the first block and the top of the second block, and mounting platesare fixedly mounted at the ends, away from the first block and the second block, of the two mounting columns. Due to rebound force of a limiting spring, when the second block drives the bracket to beslightly adjusted, moving is more stable; the fixing positions of the first A-frame and the second A-shaped frame relative to the bracket are adjustable, so that the bracket can be moved and adjustedto adapt to the position of an arm root section, the bracket and the arm root section can correctly collide with each other, an anti-collision main chord of the arm root section is effectively impacted, dislocation collision and working condition deterioration caused by stress are avoided, and the practicability of the bracket is improved.

    本发明提供一种塔式起重机可调节支架,涉及支架技术领域,包括一号A字架和二号A字架,一号A字架的外表面通过螺栓转动连接有一号块,二号A字架的外表面一侧侧壁开设有限位槽,限位槽的内壁滑动连接有二号块,一号块和二号块的顶部均固定安装有安装柱,两个安装柱分别远离一号块和二号块的一端固定安装有安装板。本发明,限位弹簧的回弹力,使得二号块带动支架微调时,移动更加平稳,由于一号A字架和二号A字架与支架的固定位置是可调节的,因此,可以进行移动和调节,以适应臂根节的位置,使二者能够正确的碰撞,有效冲击臂根节防碰撞主弦处,避免形成错位碰撞和受力导致的工况恶化等情况发生,提高了该支架的实用性。
