The invention relates to the technical field of cranes, in particular to a fixed gantry crane. Comprising a crane body; a crane boom is arranged on the crane main body, three groups of steel wire ropes are arranged on the upper end surface of one side, close to the crane main body, of the crane boom through winding shafts, the steel wire ropes positioned on two sides bypass the end part of the crane boom and are connected with a supporting block, the supporting block is of a cylindrical structure with a closed upper end, and a grabbing mechanism is arranged in the supporting block; the steel wire rope located in the middle bypasses a crane boom and is connected with the grabbing mechanism, and a positioning mechanism is arranged on the lower portion of the supporting block. The problems that in the using process of an existing fixed gantry crane, a cable is prone to being damaged when the hollow shaft is fixed through the cable, meanwhile, the hollow shaft is not convenient to put down, safety risks exist, the operation of fixing the hollow shaft through the cable is tedious, and the loading and unloading efficiency of the hollow shaft is affected are mainly solved.
本发明涉及起重机技术领域,特别涉及一种固定式门座起重机;包括起重机主体;所述的起重机主体上设置有起重机臂架,起重机臂架靠近起重机主体的一侧上端面均通过收卷轴设置有三组钢丝绳,位于两侧的钢丝绳绕过起重机臂架端部连接有支撑块,支撑块为上端封闭的筒状结构,支撑块的内部设置有抓取机构,且位于中部的钢丝绳绕过起重机臂架与抓取机构连接,支撑块的下部设置有定位机构;本发明解决了目前的固定式门座起重机在使用过程中主要存在的缆绳固定中空轴容易造成缆绳损坏,同时不便于中空轴的放下,存在安全风险,以及中空轴通过缆绳固定操作繁琐,影响中空轴的装卸效率等问题。
