The invention discloses a hoisting machine convenient to install and an installation method thereof, relates to the technical field of crane machine installation, and aims to solve the problems that when an existing portal crane is installed, after a main beam is hoisted to a certain height, the time needed for installing a lower supporting structure is long, and the main beam may fall off at any time due to construction errors in the process; and the construction risk is high. The method comprises the steps that firstly, a steel supporting mechanism and a cross beam system are conveyed to a crane installation site through a carrying vehicle; step 2, after reaching a site, the carrying vehicle firstly lowers the two groups of steel supporting mechanisms to hoists at guide rails on the two sides, four groups of hydraulic telescopic rods on the hoists extend out and are fixed with connecting holes in first hoisting connecting blocks and second hoisting connecting blocks on the two sides of the steel supporting mechanisms, and after the connection is finished, the hydraulic telescopic rods of the hoists are driven to drive the steel supporting mechanisms to move up and down; the lifting frame and the steel supporting mechanism are driven to erect, so that the walking mechanism at the bottom of the steel supporting mechanism is positioned with the guide rail.
本发明公开了一种便于安装的起重机械及其安装方法,涉及起重机机械安装技术领域,为解决现有门式起重机安装时,吊运主梁至一定高度后,安装下支撑结构所需时间较长,过程中因施工误差,随时可能出现主梁坠落情况,施工风险大的问题。步骤一:由运载车辆分别将钢支撑机构和横梁系统运送至起重机安装位点;步骤二:到达位点后,运载车辆首先将两组钢支撑机构分别下放至两侧导轨处的起升机,起升机上的四组液压伸缩杆伸出,与钢支撑机构两侧第一起升连接块、第二起升连接块上的连接孔固定,连接完毕后,起升机液压伸缩杆驱动,带动起升架以及钢支撑机构竖起,使钢支撑机构底部的行走机构与导轨定位。
