According to the derrick mast crane with the stepping type jacking device, a first hoop and a second hoop are locked, fixed and matched with a tower body through pin shafts, the position height of the derrick mast crane can be flexibly adjusted through a jacking oil cylinder according to the site construction requirement, stepping type ascending or descending is conducted, further, the second hoop is in sliding fit with a guide rail cross beam, and therefore the derrick mast crane can be lifted or lowered. The derrick mast crane can be pushed manually or mechanically to move in the horizontal direction, a hydraulic variable-amplitude oil cylinder fixedly connected with the cargo boom is further arranged on the tower cap, the cargo boom does compound motion in the horizontal direction and the vertical direction through the telescopic length of the hydraulic variable-amplitude oil cylinder, and then the working angle of the cargo boom is changed. A slewing bearing is connected between the tower cap and the tower body, the tower cap can rotate by 360 degrees through the slewing bearing, and the construction direction of the cargo boom is controlled.
本发明公开了一种具有步进式顶升装置的扒杆吊,通过销轴将第一抱箍和第二抱箍与塔身锁紧固定配合,根据现场施工需求,利用顶升油缸可灵活调整扒杆吊的位置高度,进行步进式的上升或降低,进一步地,第二抱箍与导轨横梁滑动配合,可以利用人力或机械推动扒杆吊,使扒杆吊在水平方向上进行移动,在塔帽上还设置了与起重臂固定连接的液压变幅油缸,通过液压变幅油杆的伸缩长度以让起重臂在水平和竖直方向上做复合运动,进而改变起重臂的工作角度,塔帽与塔身之间连接有回转支承,塔帽通过回转支承可进行360°的旋转运动,控制起重臂的施工方向。
