The invention relates to the technical field of cranes, and discloses a crane beam for a crane, which comprises an adjusting mechanism, a moving mechanism, a lifting mechanism and a fixing mechanism. The stepping motor operates to drive the bidirectional threaded rod to rotate, the bidirectional threaded rod rotates to enable the two first sliding blocks to move reversely, the first sliding blocks drive the sleeves to move, the sleeves drive the limiting plates to move, the limiting plates drive the sleeve rods to move, the sleeve rods drive the mounting rods to move along the racks, and the mounting rods drive the wire guide wheels to move. The distance between the two wire guide wheels can be adjusted so as to meet the hoisting requirements of goods with different lengths, the goods can shake left and right due to inertia in the goods moving process, the goods drive the hoisting rope to shake, certain oblique force can be applied to the wire guide wheels in the shaking process of the hoisting rope, the wire guide wheels can apply the oblique force to the mounting rod, and the rack can play a supporting role on the mounting rod; the influence of cargo shaking on the first sliding block and the bidirectional threaded rod is reduced, and the service life of the first sliding block and the bidirectional threaded rod is prolonged.
本发明涉及起重机技术领域,且公开了一种用于起重机的起重机梁,包括调节机构、移动机构、升降机构和固定机构。本发明通过步进电机运行带动双向螺纹杆旋转,双向螺纹杆旋转使两个第一滑块反向移动,第一滑块带动套筒移动,套筒带动限位板移动,限位板带动套杆移动,套杆带动安装杆沿着齿条移动,安装杆带动导线轮移动,可以调节两个导线轮之间的距离,以适应不同长度的货物吊装需求,在货物移动过程中因惯性会发生左右晃动,货物带动吊绳晃动,吊绳晃动的过程中会对导线轮施加一定斜向力,导线轮会施加给安装杆,齿条会对安装杆起到支撑作用,减少因货物晃动对第一滑块和双向螺纹杆的影响,提高第一滑块和双向螺纹杆的使用寿命。
