The invention relates to the technical field of wall cranes, and discloses a wall telescopic rotary crane. Guide rails are arranged at the bottom ends of two side walls of a fixing boom, and rollers are arranged in the length direction of the fixing boom through bearing wheel seats; bearing wheel walking rails are arranged on the outer walls of the two sides of a telescopic boom in the length direction of the telescopic boom; the telescopic boom is arranged in the fixing boom in a sliding fit mode through the bearing wheel walking rails arranged on the outer walls of the two sides of the telescopic boom, and bearing wheels arranged on the inner walls of the two sides of the fixing boom, and guide wheels corresponding to the guide rails at the bottom ends of the two side walls of the fixingboom are arranged at the lower end of the telescopic boom; a telescopic boom control motor is arranged on the top of the fixing boom; and the telescopic boom is connected with an output shaft of thetelescopic boom control motor through a transmission mechanism. The telescopic rotary crane can run in a limited space, is low in noise, high in telescopic precision and rotating precision, and reliable in rotary braking, and the position precision of a lifting hook can be known at any time; and the precision is high.

    本发明涉及墙式起重机技术领域,公开了一种墙式伸缩旋转起重机,固定臂架两侧壁底端均设置有导向轨道,滚轮通过支承轮座沿固定臂架长度方向布置,支承轮行走轨道沿伸缩臂架长度方向布置设置于伸缩臂架的两侧外壁上;伸缩臂架通过其两侧外壁上设置支承轮行走轨道与固定臂架两侧内壁上的支承轮滑动配合设置于固定臂架中,伸缩臂架下端设置有与固定臂架两侧壁底端的导向轨道相对应的导向轮,伸缩臂架控制电机设置于固定臂架顶部,伸缩臂架通过传动机构与伸缩臂架控制电机的输出轴连接。本发明能够在受限空间中运行、噪音小,伸缩精度高、旋转精度高、旋转制动可靠,能时刻知道吊钩的位置精度,提供了一种高精度的墙壁式起重机。
