Adjustable safety maintenance ladder for aviation maintenance
The invention discloses an adjustable safety maintenance ladder for aviation maintenance, and relates to the technical field of elevators. The adjustable safety maintenance ladder for aviation maintenance comprises a rectangular frame, a plurality of inclined supports and a plurality of steps, step plates are fixedly connected with one surfaces of the inclined supports, and the lower end faces of the inclined supports are fixedly connected with the upper surface of the rectangular frame. According to the adjustable safety maintenance ladder for aviation maintenance, a conical part and a screw rod shaft are used, when the screw rod shaft rotates, a platform can ascend and descend along a mounting plate, the height is adjusted, in addition, when the platform ascends and descends, the conical part can rotate to ascend or descend, under the condition of snowing, snow can be accumulated and frozen in a lifting groove, the conical part can play a role in breaking ice, and convenience and practicability are achieved; and rolling wheels, a spring, a matching block and a fixing block are used, when the platform ascends and descends along the mounting plate, a baffle moves along with the platform, the rolling wheels of the baffle can abut against the mounting plate, meanwhile, the rolling wheels can retract into a sliding groove after being pressed, then the rolling wheels can rebound under the action of the spring, the structure plays a buffering role, and the baffle and the mounting plate are prevented from being clamped during relative sliding.
本发明公开了一种航空维修用可调式安全维修梯，涉及升降梯技术领域。本发明包括矩形框架、若干斜支架和若干阶梯，阶梯板与斜支架一表面固定连接，斜支架下端面与矩形框架上表面固定连接。本发明通过使用锥形件和螺杆轴，当螺杆轴转动时平台可以沿安装板升降，调整高度，另外平台在升降时锥形件也会旋转上升或下降，在下雪的情况下，升降槽会积雪结冰，锥形件可以起到碎冰的效果，方便实用；本发明通过使用滚轮、弹簧、配合块和固定块，当平台沿安装板升降时，挡板也随之运动，其中挡板的滚轮可以与安装板相抵，同时滚轮受压后可以收缩进入滑槽，之后可以在弹簧的作用下回弹，该结构起到缓冲作用，避免挡板与安装板相对滑动时被卡住。
