The invention relates to a leveling limiting safety device for a platform elevator. The leveling limiting safety device for the platform elevator comprises a main machine used for driving a manned platform to ascend and descend and further comprises a reading head, a magnetic ruler and a controller; the reading head is mounted on the manned platform, the magnetic ruler is arranged in the length direction of an elevator shaft and is close to the reading head, and the controller is electrically connected with the main machine and the reading head. By only arranging the reading head to be matched with the magnetic ruler to monitor the position and the moving speed of the manned platform and controlling the main machine through the controller, the function of the leveling device is achieved, the occupied space is small, and the leveling limiting safety device for the platform elevator can be suitable for the mounting condition of the platform elevator.
本发明涉及一种平台电梯用平层限位安全装置,包括用于带动载人平台升降的主机,还包括读数头、磁尺以及控制器,读数头安装在载人平台上,磁尺沿电梯井道的长度方向设置,且磁尺靠近读数头设置,控制器与主机以及读数头电性连接。其仅设置读数头与磁尺配合,监测载人平台的位置与移动速度,并通过控制器控制主机,实现平层装置的功能,占用空间较小,可以适用于平台电梯的安装条件。
