The invention discloses a stable material lifting device for construction machinery, which comprises a bottom plate, the top end of the bottom plate is fixedly connected with a fixing frame, a servo motor is fixedly mounted in the fixing frame, the output end of the servo motor is provided with a transmission belt, the end, away from the servo motor, of the transmission belt is sleeved with a screw rod, and the screw rod is rotatably connected with the inner wall of the fixing frame. The surface of the screw is in threaded connection with a movable block, the end, away from the screw, of the movable block is fixedly connected with a platform, and the bottom end of the platform is fixedly connected with an electric rod. When the equipment needs to work, the hydraulic rod is started and stretched to drive the positioning plate to move downwards and make contact with the ground, the idler wheels are separated from the ground, and therefore the purpose of improving the stability of the equipment when the equipment works is achieved, and when the equipment needs to move, the hydraulic rod is started and contracted again to drive the positioning plate to move, so that the positioning plate is separated from the ground; and the rollers are in contact with the ground, so that the equipment can move.

    本发明公开了一种稳定型建筑机械用物料升降装置,包括底板,底板的顶端固定连接有固定架,固定架的内部固定安装有伺服电机,伺服电机的输出端设置有传动带,传动带远离伺服电机的一端套接有螺杆,螺杆与固定架的内壁转动连接,螺杆的表面螺纹连接有活动块,活动块远离螺杆的一端固定连接有平台,平台的底端固定连接有电动杆。本发明在设备需要工作时,液压杆启动,伸展并带动定位板向下移动,并与地面接触,使滚轮与地面分离,从而达到在设备工作时,增加设备稳定性的目的,在设备需要移动时,液压杆再次启动,收缩并带动定位板进行移动,使定位板与地面分离,使滚轮与地面接触从而达到使设备可以移动的目的。
