The invention belongs to the field of cranes, and particularly relates to a reinforcing device for a crane stand column. The reinforcing device comprises a stand column, a cross beam, a motor hoist, a ring seat, hydraulic cylinders and a chassis. The cross beam is rotatably installed at the top end of the stand column, the motor hoist is slidably installed at the bottom of the cross beam, and an outer ring in the middle of the stand column is fixedly connected with the ring seat; the plurality of hydraulic cylinders are rotatably installed on the outer ring at the bottom of the ring seat, and the bottom ends of piston rods of the hydraulic cylinders are in ball connection with the chassis. The motor hoist lifts a heavy object to move along the cross beam, and meanwhile, the cross beam rotates around the stand column under the driving of the motor, so that the heavy object is lifted and carried. The hydraulic cylinders push the chassis to move downwards, so that the chassis is in contact with and extrudes the ground; the hydraulic cylinders surround the outer ring of the stand column to form a plurality of inclined supporting points, so that the supporting strength of the stand column is enhanced, the supporting strength of gravity center change when the heavy object moves is improved, the probability that a crane topples over is reduced, then the maximum working weight of the crane is improved, and the operation safety of the crane is improved.

    本发明属于起重机领域,具体的说是一种起重机立柱的加固装置,包括立柱、横梁、电葫芦、环座、液压缸和底盘;所述立柱的顶端转动安装横梁,所述横梁的底部滑动安装电葫芦,所述立柱的中部外圈固接环座,所述环座的底部外圈转动安装多个液压缸,所述液压缸的活塞杆底端球接底盘;电葫芦吊起重物沿着横梁移动,同时横梁在电机的驱动下围绕立柱转动,实现了对重物的吊起搬运工作;液压缸推动底盘向下移动,使得底盘接触挤压地面,多个液压缸围绕立柱的外圈形成多个斜向支撑点,加强了立柱的支撑强度,从而提高了对重物移动时重心变化的支撑强度,降低了起重机倾倒的概率,继而提高了起重机的最大工作重量,提高了起重机的运行安全性。
