The invention provides a tower body and tower crane section variable cross-section conversion device which comprises a first cross-section standard section and a second cross-section standard section and further comprises a cross beam arranged between the first cross-section standard section and the second cross-section standard section and connected with the first cross-section standard section and the second cross-section standard section through bolts, and the cross beam comprises a first beam and a second beam. The first beam and the second beam intersect in the middle of the cross beam, a guide assembly extending in the length direction of the second beam is arranged in the middle of the first beam, a limiting groove extending in the length direction of the second beam is formed in the position, corresponding to the first beam, of the second beam, and the guide assembly abuts against the limiting groove; according to the tower crane, the maximum independent height of the tower crane can be increased by utilizing the characteristic that the tower body has different cross sectional areas under the condition that an attached wall is inconvenient or cannot be increased, the windward area of the tower body can be reduced, and the stability of the tower crane is improved.
本申请提供一种塔身塔机节变截面转换装置,包括第一截面标准节与第二截面标准节还包括:十字梁,所述十字梁设于所述第一截面标准节与所述第二截面标准节之间,并与其螺栓连接,所述十字梁包括第一梁和第二梁,所述第一梁与所述第二梁在所述十字梁的中部交叉,在所述第一梁的中部设有延所述第二梁长度方向延伸的导向组件,在所述第二梁与所述第一梁相对应的位置开设有沿其长度方向延伸的限位槽,所述导向组件与所述限位槽抵接;本申请中的塔机利用塔身具有不同横截面积的特性可以在不方便或者不能增加附墙的情况下,增加塔机的最大独立高度,还可以减小塔身的迎风面积,提高塔机的稳定性。
