The invention relates to the technical field of crane beams, in particular to a crane beam for a crane, which comprises a fixed beam and a walking beam, traction mechanisms are mounted at two ends of the fixed beam, walking frames are fixedly connected to two ends of the walking beam, through grooves are formed in the walking frames, rollers are arranged in the through grooves, and the walking frames horizontally move along the fixed beam through the rollers. A through groove is formed in the walking frame, a vertical first limiting groove is formed in the through groove, rotating shafts are fixedly connected to the two sides of the rolling wheel and located in the first limiting groove, a leakage groove matched with the through groove is formed in one end of the fixed beam, and a second limiting groove matched with the first limiting groove is formed in the leakage groove. Compared with the prior art, according to the technical scheme, the lubricating and dismounting efficiency of the roller is simplified, and the maintenance efficiency of the crane beam is greatly improved.
本发明涉及起重机梁技术领域,尤其公开了一种用于起重机的起重机梁,包括固定梁和行走梁,固定梁的两端安装有牵引机构,行走梁的两端固定连接有行走架,行走架开设有贯通槽,贯通槽内设有滚轮,行走架通过滚轮沿着固定梁水平移动,贯通槽内设有竖直的第一限位槽,滚轮的两侧固定连接有转轴,转轴位于第一限位槽内,固定梁的一端设有与贯通槽相匹配的漏槽,漏槽内设有与第一限位槽相匹配的第二限位槽,行走架移动至贯通槽与漏槽对齐时,第一限位槽与第二限位槽对接连通,与传统技术相比,本技术方案简化了滚轮的润滑和拆卸效率,大大提高了起重机梁的维修保养效率。
