The invention relates to the technical field of cranes, and particularly discloses a double-beam crane which comprises two main beam rails in bilateral symmetry and a lifting unit arranged on the main beam rails, the lifting unit comprises a lifting pulley, a grab bucket unit is arranged at the bottom of the lifting pulley, and a clamping unit and a vibration unit are arranged on the grab bucket unit. The grab bucket unit comprises a grab bucket, a hydraulic cylinder and a moving plate fixedly installed at the output end of the hydraulic cylinder, the telescopic stroke of the output end of the hydraulic cylinder is utilized, the output end of the hydraulic cylinder pushes the moving plate to move downwards, firstly, a pressing rod is driven to move downwards to extrude a second spring telescopic rod, and an adjusting plate drives a semi-cylinder to rotate to release clamping of an extrusion block; the two grab buckets are controlled to be clamped, then the two grab buckets are controlled to be opened, meanwhile, the lower driving piece of the mounting frame is driven to drive the impact plate to continuously and intermittently impact the grab buckets, and therefore the operations of grabbing materials, releasing clamping of the grab buckets and vibrating the grab buckets in the discharging process are completed through single driving.
本发明涉及起重机技术领域,具体公开了一种双梁起重机,包括左右对称的两根主梁轨道和设置在主梁轨道上的起重单元,起重单元包括起重滑轮,起重滑轮底部设置有抓斗单元,抓斗单元上设置有卡接单元和震动单元,抓斗单元包括抓斗、液压缸和固定安装在液压缸输出端的移动板,通过对液压缸输出端伸缩的行程进行利用,液压缸的输出端推动移动板向下移动首先带动压杆向下移动挤压弹簧伸缩杆二,使调节板带动半圆柱旋转解除对挤压块的卡接,以解除对两个抓斗的卡接,然后控制两个抓斗张开,同时带动安装架下驱动件驱动撞击板不断间歇碰撞抓斗,从而实现了单一驱动完成抓料、解除对抓斗的卡接以及下料过程中震动抓斗的操作。
