The invention discloses a building lifting device with a positioning function. The building lifting device comprises a lifting appliance, wherein a vertically distributed dynamic stabilizing part is fixedly arranged in the middle of the interior of the lifting appliance. According to the building lifting device, the vertically distributed dynamic stabilizing part is arranged in the lifting appliance; inner sliding columns and outer sliding columns located on the two sides of the inner sliding columns are arranged in the dynamic stabilizing part; opposite bending shafts are arranged at one endsof the two outer sliding columns; the bottoms of the inner sliding columns are fixedly connected with the two bending shafts through T-shaped pneumatic three-way elastic pistons; the inner sliding columns are sleeved with counterweight sliding sleeves; the two inner sliding columns are sleeved with unit sliding sleeves; and after pulse high-pressure gas is introduced into the T-shaped pneumatic three-way elastic pistons, the unit sliding sleeves and the counterweight sliding sleeves can be pushed to slide upwards at a high speed at a high pressure, in the process, the inner sliding columns and the outer sliding columns can swing along with the lifting appliance, the direction of the impulse generated by the high-speed movement of the unit sliding sleeves and the counterweight sliding sleeves needs to be changed by external force, and the external force forms the resistance of the swing of the lifting appliance, so that the amplitude and the time length of the swing can be reduced, andthe swing tends to be stable.
本发明公开了一种具有定位功能的建筑起吊装置,包括吊具,所述吊具内的中部固定设置有竖直分布的动态稳定部。本发明中,在吊具内设置竖直分布的动态稳定部,动态稳定部内设置内滑柱和位于内滑柱两侧的外滑柱,两个外滑柱的一端设置对向折弯轴,内滑柱的底部通过T型气动三通弹性活塞和两个折弯轴固定连接,内滑柱上套设有配重滑套,两个内滑柱上均套设有单元滑套,向T型气动三通弹性活塞内通入脉冲高压气体后,可以高压推动单元滑套和配重滑套向上高速滑动,在此过程中内滑柱和外滑柱会跟随吊具摆动,而单元滑套和配重滑套高速运动产生的冲量的方向的改变需要外力,此外力形成吊具摆动的阻力,由此可以降低摆动的幅度和时长并使其趋于稳定。
