The invention relates to the technical field of double-beam grab bucket cranes, in particular to an electric double-beam grab bucket crane which comprises a double-beam bridge frame, a walking trolley, a rope unit and a grab bucket unit. A motor I drives a winding drum to rotate in the forward direction and drives a traction rope and a grab bucket to move downwards, and a distance control air cylinder drives the grab bucket to be opened and closed; through cooperation of a material picking frame and a collecting frame, the materials entering the grabbing hopper for the first time are conveyed to dead corners on the two sides of the grabbing hopper, the distance control air cylinder drives the grabbing hopper to grab the materials again, the materials dug for the second time enter the middle of the grabbing hopper, it is guaranteed that the interior of the grabbing hopper is filled with the materials, and the material grabbing amount of the grabbing hopper is increased; and the closed grabbing hopper is limited through the force balancing frame, the situation that the grabbing hopper is opened in the material conveying process, and consequently materials are scattered and leaked is avoided, the materials on a moving path do not need to be collected in the later period, and the use cost of the electric double-beam grab bucket crane is reduced.

    本发明涉及双梁抓斗起重机技术领域,具体为一种电动双梁抓斗起重机,包括双梁桥架、行走小车、绳索单元与抓斗单元,本发明通过电机一带动收卷筒正向转动,带动牵引绳索与抓料斗向下运动,通过控距气缸带动抓料斗张开关闭,对物料进行抓取,通过拾料架与收集架相配合,将第一次进入抓料斗的物料输送至抓料斗两侧死角,通过控距气缸带动抓料斗再次抓取物料,第二次挖取的物料进入抓料斗中部,保证抓料斗内部充满物料,提高抓料斗的抓取物料的量,从而提高起重机的工作效率,通过衡力架对闭合的抓料斗进行限位,防止其在输送那个物料的过程中张开,导致物料撒漏,无需后期对移动路径上的物料进行收集,降低了电动双梁抓斗起重机的使用成本。
