The invention provides an anti-slip heavy tower crane attachment device hinged to a thin-wall circular steel column, which comprises an anti-slip joint assembly and a ring beam assembly, the anti-slip joint assembly and the ring beam assembly are connected through a connecting mechanism, the anti-slip joint assembly is used for connecting a tower crane attachment rod head, a plurality of slots are formed in the ring beam assembly, and the ring beam assembly is connected with the anti-slip joint assembly. And the steel column is wedged and fixed through the matching of the plurality of inserting blocks and the inserting grooves. Therefore, the problems that an existing cylinder is connected by adopting a hoop structure, a hoop steel plate cannot independently resist horizontal axial push/pull force from an attachment rod due to the fact that the bending modulus of the hoop steel plate is very small, and axial pressure acts on the cylinder in a local and one-way load after passing through a hoop arc-shaped plate (a base plate) can be solved; if the column body is a thin-walled/hollow steel structure column body with relatively weak overall strength, the column body is easy to deform under the extrusion of the attachment rod.

    本发明提供了一种铰接于薄壁圆形钢柱的防滑转式重型塔机附着装置,包括防转接头总成和环梁总成,防转接头总成和环梁总成通过连接机构连接,防转接头总成用于连接塔机附着杆杆头,环梁总成上设有若干插槽,钢柱通过若干插块与插槽的配合实现钢柱的楔紧固定。由此,本发明能够解决现有的柱体常采用“抱箍”结构连接,由于抱箍钢板本身抗弯模量很小,不能单独抵抗来自附着杆水平的轴向推/拉力,轴向压力通过抱箍弧形板(垫板作用)后以局部、单向的载荷作用到柱体上,如果是薄壁/空心等整体强度相对较弱的钢结构柱体,则很容易使得柱体在附着杆的挤压下发生变形的技术问题。
