The invention relates to the technical field of gantry crane equipment, and discloses gantry crane equipment based on hydraulic motor driving, which comprises two self-propelled supports, a portal frame is fixedly mounted between the self-propelled supports, a main bearing block capable of moving left and right is movably mounted at the top of an inner cavity of the portal frame, and a cable roller is mounted in an inner cavity of the bottom of the main bearing block in a driving manner; the periphery of the rope roller is fixedly connected with two groups of winding slings, the movable ends of the slings are fixedly connected with the inner wall of the main bearing block, a hook block is movably sleeved between the slings, and the bottom of the hook block is fixedly connected with a lifting hook. The auxiliary bearing block synchronously moves along with the main bearing block, when the rope roller releases the sling to drive the hook block and the lifting hook to move downwards, the auxiliary bearing block is in lap joint with the limiting frame on the hook block, the auxiliary bearing block synchronously moves downwards under the action of gravity, and therefore the hook block is limited to move in multiple directions, and the situation that when the lifting hook hangs goods, the lifting hook easily shakes due to release of the sling is avoided; the use safety is ensured, and the hoisting and transferring efficiency is improved.
本发明涉及龙门吊设备技术领域,且公开了一种基于液压马达驱动的龙门吊设备,包括两个自走支座,所述自走支座之间固定安装有龙门架,所述龙门架内腔顶部活动安装有能左右移动的主承块,所述主承块底部内腔驱动安装有索辊,所述索辊外围固定连接有两组缠绕的吊索,所述吊索活动端固定连接所述主承块内壁,所述吊索之间活动套接有钩块,所述钩块底部固定连接有吊钩。本发明,通过副承块跟随主承块同步移动,在索辊释放吊索带动钩块及吊钩下移时,利用副承块搭接在钩块上的限位框,在重力作用下同步下移,从而对钩块多方向限移,避免了吊钩吊挂货物时,因吊索的释放而容易出现晃动的情况,保证了使用安全,提升了吊装移运的效率。
