The invention discloses a sliding structure for cooperation between a standard section and a jacking sleeve frame of a tower crane. The sliding structure comprises the standard section and the jackingsleeve frame. The standard section is of a space truss structure composed of four first main limbs and supporting rod pieces, flange plates are fixedly arranged on the upper end face and the lower end face of each first main limb, each flange plate comprises right-angled end sliding blocks, and the right-angled end sliding blocks are located on the outer side of the cross section of each first main limb. Right-angled middle sliding blocks are arranged between the upper end face and the lower end face of each first main limb. The jacking sleeve frame is of a space truss structure composed of four second main limbs and supporting rod frames, sliding ways are fixedly arranged on the inner sides of the lower portions of the second main limbs, the standard section is sleeved with the jacking sleeve frame, and the jacking sleeve frame is matched with the right-angled end sliding blocks and the right-angled middle sliding blocks on the standard section through the sliding ways so as to slideup and down. By the adoption of the above structure, sliding motion between the standard section and the jacking sleeve frame is more reasonable and smooth.
本发明公开了一种塔式起重机标准节与顶升套架之间配合的滑动结构,包括标准节与顶升套架,标准节是由四个第一主肢及支撑杆件构成的空间桁架结构,每个第一主肢上端面和下端面均固定设置有法兰板,法兰板包括端部直角滑块,端部直角滑块位于第一主肢横截面的外侧。在每个第一主肢的上端面与下端面之间设有中部直角滑块。顶升套架是由四个第二主肢及支撑杆架构成的空间桁架结构,第二主肢的下部内侧固定设置有滑道,顶升套架套设于标准节外部,顶升套架通过滑道与标准节上的端部直角滑块及中间滑块的配合,从而实现上下滑动。上述结构使标准节与顶升套架之间的滑动更为合理顺畅。
