The invention discloses a gantry crane with an auxiliary hinge point shaft system and a hinge point maintenance method.The crane comprises a seat frame and a suspension system, the suspension system comprises a large pull rod, an arm frame and a trunk beam, and one end of the large pull rod and one end of the arm frame are hinged to the seat frame; the other end of the large pull rod and the other end of the arm support are respectively hinged with the trunk beam; a first hinge seat is arranged on the side, away from the large pull rod, of the arm support, a second hinge seat is arranged on the side wall of the trunk beam, when the suspension system is adjusted to be in the minimum amplitude state, the connecting portions of the first hinge seat and the second hinge seat coincide, and the minimum amplitude state is the state that the included angle between the side, away from the large pull rod, of the arm support and the trunk beam is the minimum included angle. Maintenance platforms are installed at the hinge point position of the large pull rod and the trunk beam, the hinge point position of the arm support and the trunk beam and the installation positions of the first hinge base and the second hinge base respectively. In the maintenance process, the suspension system does not need to adjust the amplitude, the whole process is in a fixed state, safety is high, and maintenance efficiency is high.
本申请公开了一种具有辅助铰点轴系统的门座起重机及铰点维修方法,起重机包括座架和悬架系统,悬架系统包括大拉杆、臂架以及象鼻梁,大拉杆的一端以及臂架的一端分别与座架铰接,大拉杆的另一端以及臂架的另一端分别与象鼻梁铰接;臂架背离大拉杆的一侧设置有第一绞座,象鼻梁的侧壁设置有第二绞座,当悬架系统调整为最小幅度状态时,第一绞座和第二绞座的连接部位重合,最小幅度状态为臂架背离大拉杆一侧与象鼻梁之间的夹角处于最小夹角时的状态;大拉杆与象鼻梁的铰点位置、臂架与象鼻梁的铰点位置以及第一绞座与第二绞座的安装位置分别安装有维修平台。本申请维修过程中悬架系统无需调整幅度,全程处于固定状态,安全性高且维修效率高。
