The invention relates to the field of hydraulic ladder stand equipment, and particularly discloses a safety protection structure of a hydraulic ladder stand, comprising: a ladder stand body, the top of which is fixedly provided with a fixed shaft; a guide wheel groove is annularly formed in the middle of the guide wheel body, and the inner walls of the two sides of the guide wheel groove are obliquely arranged. The side pressing wheel is rotationally installed on the outer side of the guide wheel body and presses the suspension steel wire rope. The anti-falling piece is installed on the side face of the guide wheel body. The guide wheel has the beneficial effects that the guide wheel groove is formed in the middle of the guide wheel body, the side wall of the guide wheel groove is obliquely arranged, and the guide sliding groove is formed in the guide wheel body in the radial direction; the friction force between the suspension steel wire rope and the side pressing plates can drive the side pressing plates to slide to the groove bottom of the guide wheel groove, at the moment, the side pressing plates on the two sides of the guide wheel groove get close to each other and clamp the suspension steel wire rope, and the situation that the suspension steel wire rope jumps and is disengaged from an inner cavity of the guide wheel groove is avoided.
本发明涉及液压爬梯设备领域,具体公开了一种液压爬梯的安全防护结构,包括:爬梯本体,爬梯本体的顶部固定设置有固定轴;导轮本体的中部环形开设有导轮凹槽,导轮凹槽的两侧内壁均倾斜设置;侧压轮转动安装于导轮本体的外侧并对悬吊钢丝绳压紧;防坠件安装于导轮本体的侧面;有益效果为:通过在导轮本体的中部开设有导轮凹槽,导轮凹槽的侧壁倾斜设置并沿导轮本体的径向开设有导向滑槽,当悬吊钢丝绳在吊篮的重力作用下卡进导轮凹槽内腔后,悬吊钢丝绳与侧压板之间的摩擦力能够驱动侧压板向导轮凹槽的槽底滑动,此时导轮凹槽两侧的侧压板相互靠近并对悬吊钢丝绳进行夹紧,避免悬吊钢丝绳发生跳动而与导轮凹槽的内腔脱离。
