The invention relates to the technical field of sand core hoisting, in particular to a hoisting overturning device. The hoisting overturning device comprises a cross beam, a clamping arm, a transmission mechanism and a self-locking mechanism; the clamping arm is arranged on the cross beam in a sliding manner; the transmission mechanism comprises a main rotating shaft and a clamping positioning block, wherein the clamping positioning block is arranged at the end, away from the cross beam, of the clamping arm, the clamping positioning block is used for being inserted into a positioning hole of asand core, and the clamping positioning block is connected with the main rotating shaft and can rotate along with rotation of the main rotating shaft; and the self-locking mechanism is arranged at the first end of the cross beam and can lock the main rotating shaft to limit rotation of the clamping positioning block. According to the hoisting overturning device, the self-locking mechanism can lock the main rotating shaft and limit rotation of the clamping positioning block after the sand core rotates, so that position change of the sand core in the hoisting process is limited, and the problems of potential safety hazards and low production efficiency of the sand core in the subsequent working process are prevented.
本发明涉及砂芯吊装技术领域,尤其涉及一种吊装翻转装置。其包括:横梁;夹持臂,其能够滑动的设置于所述横梁上;传动机构,其包括主转动轴和夹持定位块,所述夹持定位块设置在所述夹持臂远离所述横梁的一端,所述夹持定位块用于插入砂芯的定位孔内,所述夹持定位块与所述主转动轴连接并能够随主转动轴的转动而转动;自锁机构;设置于所述横梁的第一端,所述自锁机构能够对所述主转动轴进行锁定,限制所述夹持定位块转动。本发明中提供的吊装翻转装置,由于自锁机构能够在砂芯转动后对主转动轴进行锁定,限制夹持定位块转动,因此能够制约砂芯在吊装过程中产生位置改变,防止砂芯在后续工作过程中安全隐患及生产效率低的问题出现。
