Mounting device for prefabricated stairs
The invention relates to the technical field of constructional engineering, and discloses a mounting device of a prefabricated stair, a rotating shaft drives a guide wheel to rotate and wind a steel wire rope at the front and back positions of a moving block, the rotating shaft rotates upwards so as to drive a gear ring to rotate synchronously when the steel wire rope is wound upwards, and a rack is driven to move to adjust hydraulic changes of two hydraulic cavities; the telescopic block shrinks towards the interior of the first hydraulic cavity so as to drive the whole moving block to move towards the middle of the support, the moving block is driven to move when the steel wire rope is wound upwards, it is guaranteed that the steel wire rope is always kept in a vertical state, labor is saved, and the service life of tension pieces such as the steel wire rope is prolonged; and the bottom of the telescopic rod is connected with the abutting head, when one end of the prefabricated stair is lifted, the two arc plates arranged on the abutting head abut against the top face of the step to judge the lifting horizontal condition, the two ends of the stair are tightly abutted when the end reaches the installation horizontal position, and the stability of lifting and moving the prefabricated stair is guaranteed.
本发明涉及建筑工程技术领域，且公开了一种预制楼梯的安装装置，在移动块的前后位置通过转动轴驱动导轮转动收卷钢丝绳，转动轴转动向上从而向上收卷钢丝绳的时候会带动齿环同步转动，并带动齿条移动调节两个液压腔液压变化，使得伸缩块向第一液压腔内部收缩从而带动移动块整体向支架中部处移动，在向上收卷钢丝绳的时候带动移动块移动，保证钢丝绳始终保持竖直状态，省力且提高钢丝绳等拉力件的使用寿命，在移动块的底部设置有收缩杆和伸缩杆，并且伸缩杆的底部连接有抵头，在抬升预制楼梯一端时，利用抵头上设置的两个弧板抵压台阶顶面来判断抬升的水平状况，且达到安装水平位置时抵紧楼梯两端，保证了在吊装移动预制楼梯的稳定性。
