The invention relates to the technical field of special equipment, and discloses a moment limiter for a tower crane, which comprises a first mounting plate and a second mounting plate, a plurality of detection screw rods are mounted on the first mounting plate, and a detection head is arranged at one end of each detection screw rod; a plurality of photoelectric sensors are mounted on the second mounting plate, the photoelectric sensors and the detection screws are the same in number and are in one-to-one correspondence, and the photoelectric sensors are used for detecting the distance between the photoelectric sensors and the detection heads. According to the technical scheme, a sensor in the moment limiter is replaced by the photoelectric sensor, and the photoelectric sensor has the advantages of high precision, quick response, non-contact and the like, so that the moment limiter can adapt to some complex environments, the reliability of the moment limiter during working of the tower crane is improved, and the risk of safety accidents is reduced.

    本发明涉及特种设备技术领域,公开了一种用于塔式起重机的力矩限制器,包括第一安装板和第二安装板;所述第一安装板上安装有若干检测螺杆,所述检测螺杆的一端设有检测头;所述第二安装板上安装有若干光电传感器,所述光电传感器与检测螺杆数量相同且一一对应,所述光电传感器用于检测光电传感器与检测头之间的距离。通过采用本申请的技术方案,将力矩限制器中的传感器替换为光电传感器,而光电传感器具有精度高、反应快、非接触等优点,能够适应一些复杂的环境,提升力矩限制器在塔式起重机工作时的可靠性,降低安全事故发生的风险。
